Questions and Answers
  • 1. 

    The patients with congestive heart failure may have all of these conditions, except:

    • A.

      Extreme headache

    • B.

      Extreme dyspnea

    • C.

      Hyperventilation

    • D.

      Cyanosis

    Correct Answer
    A. Extreme headache
    Explanation
    Congestive heart failure is a condition where the heart is unable to pump enough blood to meet the body's needs. This can lead to symptoms such as dyspnea (shortness of breath), hyperventilation (rapid breathing), and cyanosis (bluish discoloration of the skin). However, extreme headache is not typically associated with congestive heart failure. Headaches may occur due to other factors such as high blood pressure, but they are not a direct symptom of congestive heart failure.

    • A.

      Teary eyes

    • B.

      Cough

    • C.

      Hemoptysis

    • D.

      Difficulty in breathing

    Correct Answer
    A. Teary eyes
    Explanation
    Congestive heart failure is a condition where the heart is unable to pump blood effectively, leading to fluid buildup in the body. Symptoms commonly associated with congestive heart failure include cough, hemoptysis (coughing up blood), and difficulty in breathing. However, teary eyes are not typically associated with congestive heart failure. This symptom is more commonly seen in conditions such as allergies or eye infections.

    The incorrect preventive measure before the surgical procedure for a patient with congestive heart failure is

    • A.

      Long painless appointments

    • B.

      Written consent from the patient’s cardiologist

    • C.

      Oral premedication

    • D.

      Small amounts of vasoconstrictors in local anesthesia

    Correct Answer
    A. Long painless appointments
    Explanation
    Long painless appointments can be detrimental for a patient with congestive heart failure because they can cause prolonged stress and anxiety, which can worsen the condition. Patients with congestive heart failure may have difficulty sitting or lying down for extended periods of time, and long appointments can lead to fluid buildup in the lungs and increased strain on the heart. Therefore, it is important to minimize the duration of appointments and provide breaks if needed to ensure the patient's comfort and safety.

    Rate this question:

    The preferred position for the patients with congestive heart failure is

    • A.

      Sitting position

    • B.

      Standing position

    • C.

      Sleeping position

    • D.

      Sleeping position with legs raised a bit upward

    Correct Answer
    A. Sitting position
    Explanation
    The preferred position for patients with congestive heart failure is the sitting position. This is because sitting upright helps to reduce the workload on the heart by promoting better blood flow and reducing fluid buildup in the lungs. It also helps to alleviate symptoms such as shortness of breath and swelling in the lower extremities. Additionally, sitting allows for better monitoring of vital signs and easier access for medical interventions if needed.

    The incorrect preventive measure before the surgical procedure for a patient with angina pectoris is

    • A.

      Oral premedication, usually 20-50mg diazepam

    • B.

      Written consent from the patient’s cardiologist

    • C.

      Small amounts of vasoconstrictors in local anesthesia

    • D.

      Dental surgery in hospital

    Correct Answer
    A. Oral premedication, usually 20-50mg diazepam
    Explanation
    The incorrect preventive measure before the surgical procedure for a patient with angina pectoris is oral premedication, usually 20-50mg diazepam. Diazepam is a benzodiazepine medication that is commonly used as a sedative or muscle relaxant. However, it is not recommended for patients with angina pectoris because it can cause respiratory depression and may interact with other medications that the patient is taking for their heart condition. Therefore, it is important to avoid using diazepam as a premedication for these patients to prevent any potential complications during the surgical procedure.

      Coughing

    • B.

      Perspiration

    • C.

      Extreme anxiety

    • D.

      A feeling of imminent death

    Correct Answer
    A. Coughing
    Explanation
    Angina pectoris is a condition characterized by chest pain or discomfort that occurs when the heart muscle doesn't receive enough blood flow. The painful symptoms of angina pectoris are typically triggered by physical exertion or emotional stress. Coughing is not typically associated with angina pectoris, as it is not a direct symptom of reduced blood flow to the heart. On the other hand, perspiration, extreme anxiety, and a feeling of imminent death are commonly reported symptoms of angina pectoris.

    False information about myocardial infarction is

    • A.

      Myocardial infarction has a sudden onset with severe pain anterior to sternum

    • B.

      Myocardial infarction refers to ischemic necrosis of an area of the heart

    • C.

      Pain of myocardial infarction is more severe than that of angina pectoris

    • D.

      Pain of myocardial infarction lasts longer than 15 minutes

    Correct Answer
    A. Myocardial infarction has a sudden onset with severe pain anterior to sternum
    Explanation
    Myocardial infarction typically has a sudden onset with severe pain anterior to the sternum. This is because myocardial infarction refers to the ischemic necrosis of an area of the heart, which occurs when blood flow to the heart muscle is blocked. The pain experienced during a myocardial infarction is usually more severe than that of angina pectoris, which is chest pain caused by reduced blood flow to the heart. Additionally, the pain of a myocardial infarction typically lasts longer than 15 minutes, as it is a serious and potentially life-threatening condition.

    Rate this question:

  • 10.

      Lip

    • B.

      Neck

    • C.

      Mandible

    • D.

      Right arm

    Correct Answer
    A. Lip
    Explanation
    The pain of myocardial infarction can radiate to various regions of the body due to the shared nerve pathways. However, the lip is not innervated by the same nerves that transmit pain signals from the heart. Therefore, pain from a myocardial infarction would not typically be felt in the lip.

    Rate this question:

  • 11. 

    All are characteristics of myocardial infarction, except

    • A.

      Pain lasting from 5 to 10 minutes

    • B.

    • C.

      Extreme tightness

    • D.

      Pressure

    Correct Answer
    A. Pain lasting from 5 to 10 minutes
    Explanation
    Myocardial infarction, also known as a heart attack, is characterized by symptoms such as burning sensation, extreme tightness, and pressure in the chest. These symptoms typically last for a longer duration, usually more than 10 minutes. Therefore, the exception in this case is pain lasting from 5 to 10 minutes, as it is not a typical characteristic of a myocardial infarction.

    Rate this question:

  • 12. 

    The pain of myocardial infarction may be associated with all, except

    • A.

      Dilation of pupils

    • B.

      Nausea

    • C.

      Vomiting

    • D.

      Perspiration

    Correct Answer
    A. Dilation of pupils
    Explanation
    During a myocardial infarction (heart attack), the heart muscle is deprived of oxygen-rich blood, leading to severe chest pain. This pain is typically associated with symptoms like nausea, vomiting, and perspiration due to the activation of the sympathetic nervous system. However, dilation of pupils is not a common symptom of myocardial infarction. Pupil dilation is more commonly associated with other conditions like drug use, neurological disorders, or eye injuries.

    Angina Pectoris

    • A.

      Is characterized by the temporary ischemia in part of or all of the myocardium.

    • B.

      Is the inability of the myocardium to pump enough blood to satisfy the body.

    • C.

      Is the ischemic necrosis of an area of the heart.

    • D.

      Is any periodic variation in the normal rhythm of heart.

    Correct Answer
    A. Is characterized by the temporary ischemia in part of or all of the myocardium.
    Explanation
    Angina Pectoris is characterized by the temporary ischemia in part of or all of the myocardium. This means that during an episode of angina, there is a temporary reduction in blood flow to the heart muscle, leading to chest pain or discomfort. The reduced blood flow is usually caused by the narrowing or blockage of the coronary arteries, which supply oxygen-rich blood to the heart. This temporary ischemia can result in symptoms such as chest pain, shortness of breath, and a feeling of tightness or pressure in the chest.

    • D.

      Is any periodic variation in the normal rhythm of heart.

    Correct Answer
    A. Is the inability of the myocardium to pump enough blood to satisfy the body.
    Explanation
    Congestive heart failure is a condition where the myocardium, which is the heart muscle, is unable to pump an adequate amount of blood to meet the needs of the body. This means that the heart is not able to effectively circulate blood, leading to symptoms such as fatigue, shortness of breath, and fluid retention. It is a chronic and progressive condition that can be caused by various factors, including damage to the heart muscle from conditions like coronary artery disease or high blood pressure. Treatment for congestive heart failure aims to improve heart function and manage symptoms.

    Myocardial infarction

    • A.

      Is the ischemic necrosis of an area of the heart.

    • B.

      Is characterized by the temporary ischemia in part of or all of the myocardium.

    • C.

      Is the inability of the myocardium to pump enough blood to satisfy the body.

    • D.

      Is any periodic variation in the normal rhythm of heart.

    Correct Answer
    A. Is the ischemic necrosis of an area of the heart.
    Explanation
    Myocardial infarction refers to the ischemic necrosis of an area of the heart. This means that there is a lack of blood supply to a specific part of the heart, leading to tissue death. This condition is commonly known as a heart attack and is caused by a blockage in the coronary arteries that supply blood to the heart muscle. The lack of blood flow results in oxygen deprivation, leading to cell death in the affected area of the heart. Prompt medical intervention is crucial to prevent further damage and improve the chances of survival.

    Chronic renal failure is

    • A.

      Clinical syndrome characterized by permanent damage of kidney

    • B.

      Clinical syndrome characterized by temporary kidney damage

    • C.

      Characterized by acute, diffused inflammation of the glomeruli.

    • D.

      Syndrome characterized by the alteration of metabolism of carbohydrates

    Correct Answer
    A. Clinical syndrome characterized by permanent damage of kidney
    Explanation
    Chronic renal failure is a clinical syndrome characterized by permanent damage of the kidney. This means that the kidneys have sustained irreversible damage, leading to a decrease in their ability to function properly. This can result in a variety of symptoms and complications, such as fluid retention, electrolyte imbalances, and the buildup of waste products in the body. Treatment options for chronic renal failure may include dialysis or a kidney transplant.

    Most common causes of chronic renal failure are all, except

    • A.

      Hypotensive nephrosclerosis

    • B.

      Nephrotoxin

    • C.

      Diabetes mellitus

    • D.

      Glomerulonephritis

    Correct Answer
    A. Hypotensive nephrosclerosis
    Explanation
    Chronic renal failure is a condition where the kidneys gradually lose their ability to function properly over time. The most common causes of chronic renal failure include nephrotoxins (substances that are toxic to the kidneys), diabetes mellitus (a chronic condition characterized by high blood sugar levels), and glomerulonephritis (inflammation of the kidney's filtering units). However, hypotensive nephrosclerosis, which refers to kidney damage caused by chronic low blood pressure, is not a common cause of chronic renal failure.

  • 38. 

    All are necessary preventive measures for the surgical procedure on patients with chronic renal failure, except

    • A.

      Dental procedure on the day of hemodialysis

    • B.

      Consultation with the patients’ nephrologist

    • C.

      Use of minimal amounts of vasoconstrictors

    • D.

      Use of minimal amounts of local anesthetics

    Correct Answer
    A. Dental procedure on the day of hemodialysis
    Explanation
    Dental procedure on the day of hemodialysis is not a necessary preventive measure for surgical procedures on patients with chronic renal failure. Hemodialysis is a procedure that removes waste and excess fluid from the blood, and it is important to avoid any additional procedures on the same day to minimize stress on the patient's body. Therefore, it is not recommended to perform dental procedures on the day of hemodialysis.

    Stenosis of ducts of small bronchi and bronchioles in the patient of asthma is due to all, except

    • A.

      Vascular hemorrhage

    • B.

      Edema of mucosa

    • C.

      Viscous mucosa production

    • D.

      Bronchoconstriction

    Correct Answer
    A. Vascular hemorrhage
    Explanation
    The correct answer is vascular hemorrhage. Stenosis of ducts of small bronchi and bronchioles in asthma patients is caused by edema of the mucosa, viscous mucosa production, and bronchoconstriction. Vascular hemorrhage is not a contributing factor to the narrowing of the airways in asthma.

    When asthma attacks, all are correct about the patient, except

    • A.

      The patient wants to vomit

    • B.

      The patient’s expression is anxious

    • C.

      The patient’s face is pale

    • D.

      The patient’s limbs are cold

    Correct Answer
    A. The patient wants to vomit
    Explanation
    During an asthma attack, the airways become inflamed and narrowed, making it difficult for the patient to breathe. Symptoms of an asthma attack include wheezing, coughing, shortness of breath, and chest tightness. Nausea or the desire to vomit is not typically associated with asthma attacks. Therefore, the statement "The patient wants to vomit" is incorrect in relation to the symptoms of an asthma attack.

    The incorrect preventive measure for patients with asthma is

    • A.

      Long appointments with little pain

    • B.

      Taking detailed medical history

    • C.

      Control of pain

    • D.

      Administration of sedative medication

    Correct Answer
    A. Long appointments with little pain
    Explanation
    Long appointments with little pain is an incorrect preventive measure for patients with asthma because it does not address the specific needs and challenges of asthma management. Asthma requires regular monitoring, medication adherence, and proper education on triggers and self-management techniques. Long appointments with little pain may not provide enough time for thorough assessment, education, and personalized treatment plans. It is important to focus on taking a detailed medical history, controlling pain, and administering appropriate medication to effectively manage asthma symptoms and prevent exacerbations.

    All are infectious diseases, except

    • A.

      Diabetes

    • B.

      Hepatitis B

    • C.

      Hepatitis C

    • D.

      AIDS

    Correct Answer
    A. Diabetes
    Explanation
    Diabetes is not an infectious disease, but a metabolic disorder characterized by high blood sugar levels. It is caused by a combination of genetic and environmental factors, and it is not transmitted from person to person like infectious diseases such as Hepatitis B, Hepatitis C, and AIDS. Diabetes is primarily a result of the body's inability to produce or effectively use insulin, a hormone that regulates blood sugar levels.

    All are correct about what to do with active tuberculosis patients, except

    • A.

      The appointment should be set in early morning at the dental office

    • B.

      The emergency dental treatment should be done in a hospital

    • C.

      The dentists and staff should take additional protection measures

    • D.

      Dental treatment should be postponed till it is confirmed that there is no danger of transmitting disease

    Correct Answer
    A. The appointment should be set in early morning at the dental office
    Explanation
    The appointment should not be set in early morning at the dental office because active tuberculosis patients are more likely to cough in the morning and potentially spread the disease to others. Therefore, it is important to schedule their appointments later in the day when the risk of transmission is lower.

    Incorrect sign or symptom of patients with tuberculosis is

    • A.

      Abdominal pain

    • B.

      Fever

    • C.

      Lassitude

    • D.

      Weight loss

    Correct Answer
    A. Abdominal pain
    Explanation
    Patients with tuberculosis typically do not experience abdominal pain as a sign or symptom. Tuberculosis primarily affects the lungs, causing symptoms such as cough, fever, and weight loss. Abdominal pain is more commonly associated with other conditions such as gastrointestinal issues or appendicitis. Therefore, abdominal pain would be an incorrect sign or symptom of tuberculosis.

    Incorrect preventive measure for dentists when a patient with infectious disease comes into the clinic is

    • A.

      Using a pair of sterilized glove

    • B.

      Programming the procedure as the last of the day

    • C.

      Good care of disposable needles

    • D.

      Discarding of surgical blades

    Correct Answer
    A. Using a pair of sterilized glove
    Explanation
    Using a pair of sterilized gloves is not an incorrect preventive measure for dentists when a patient with an infectious disease comes into the clinic. Sterilized gloves are essential for protecting both the dentist and the patient from potential infections. They create a barrier between the dentist's hands and the patient's oral cavity, preventing the transmission of pathogens. Therefore, using sterilized gloves is a necessary precautionary measure in dental clinics.

    All are true about epilepsy, except

    • A.

      Epilepsy can lead to sensory activity and altered states of consciousness

    • B.

      Epilepsy is a clinical manifestation of abnormal electrical activity of the brain

    • C.

      Epileptic patients may present with epileptic seizures under certain circumstances

    • D.

      Certain epileptic patients may present with status epilepticus

    Correct Answer
    A. Epilepsy can lead to sensory activity and altered states of consciousness
    Explanation
    Epilepsy is indeed a clinical manifestation of abnormal electrical activity in the brain. Epileptic patients may present with epileptic seizures under certain circumstances, and certain patients may also experience status epilepticus, which is a prolonged seizure or a series of seizures without full recovery in between. However, epilepsy does not necessarily lead to sensory activity and altered states of consciousness. While seizures can cause changes in consciousness, not all individuals with epilepsy experience this symptom.

      Severe pain

    • C.

      Alcoholic drinks

    • D.

      Severe stress

    Correct Answer
    A. Hyperglycemia
    Explanation
    Hyperglycemia is not a precipitating factor of epilepsy. Epilepsy is a neurological disorder characterized by recurrent seizures, which are caused by abnormal electrical activity in the brain. While severe pain, alcoholic drinks, and severe stress can trigger seizures in individuals with epilepsy, hyperglycemia, or high blood sugar levels, is not known to be a precipitating factor. Hyperglycemia is more commonly associated with diabetes and can lead to various complications, but it is not directly linked to the onset of epilepsy.
