    Propofol is

    • An inhalation anesthetic

    • General anesthetic administered intravenously

    Correct Answer
    A. General anesthetic administered intravenously
  • 4. 

    MAC or Minimum Alveolar Concentration is the minimum concentration in alveolar air that is anesthetic.  HIGH MAC means

    • High potency

    • Low potency

    • Medium potency

    • Fair potency

    Correct Answer
    A. Low potency
    Explanation
    A high MAC indicates a low potency of the anesthetic. This means that a higher concentration of the anesthetic is required in the alveolar air to achieve the desired anesthetic effect. In other words, a high MAC value indicates that the anesthetic is less effective and requires a higher concentration to produce the desired level of anesthesia.

    Rate this question:

  • 5. 

    Thiopental is

    • An intravenous anesthetic

    • An inhalant anesthetic

    Correct Answer
    A. An intravenous anesthetic

    Antiemetics

    • Reduce constipation

    • Reduce abdominal distention

    • Reduce urinary retention

    • Reduce pain

    • Reduce nausea and vomiting

    Correct Answer
    A. Reduce nausea and vomiting
    Explanation
    Antiemetics are medications that are specifically designed to reduce nausea and vomiting. They work by targeting the receptors in the brain that trigger the vomiting reflex, helping to alleviate these symptoms. While antiemetics may have other effects on the body, such as reducing constipation, abdominal distention, urinary retention, and pain, their primary purpose is to reduce nausea and vomiting.

    Surgical Anesthesia Stage. Deep unconsciousness, increased muscle relaxation

    • Stage I

    • Stage II

    • Stage III

    • Stage IV

    Correct Answer
    A. Stage III
    Explanation
    Stage III of surgical anesthesia is characterized by deep unconsciousness and increased muscle relaxation. In this stage, the patient is completely unconscious and has a loss of reflexes. The muscles are relaxed, allowing for easier surgical procedures. This stage is important for maintaining the patient's stability during surgery and ensuring that they do not regain consciousness or experience pain. It is a crucial stage for the success of the surgery and the safety of the patient.

    Rate this question:

  • 10. 

    Local anesthetics do get absorbed from injection site.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Local anesthetics are designed to temporarily block nerve signals in a specific area of the body, providing pain relief during medical procedures or surgeries. When injected, these medications are absorbed into the bloodstream from the injection site. This allows them to reach their target nerves and exert their numbing effects. Therefore, it is correct to say that local anesthetics do get absorbed from the injection site.

    Rate this question:

  • 11. 

    Which of the following is an interoperative medication?

    • Diazepam

    • Midazolam

    • Succinylcholine

    • Atropine

    Correct Answer
    A. Succinylcholine
    Explanation
    Succinylcholine is an interoperative medication because it is a neuromuscular blocking agent that is used during surgery to induce muscle relaxation and facilitate intubation. It works by blocking the action of acetylcholine at the neuromuscular junction, resulting in temporary paralysis of the muscles. This allows for easier insertion of breathing tubes and reduces the risk of injury during surgery. Diazepam, midazolam, and atropine are not interoperative medications as they have different uses and mechanisms of action.

    Rate this question:

  • 12. 

    Spinal or epidural anesthetics

    • Topical

    • Local

    • Regional

    • General

    Correct Answer
    A. Regional
    Explanation
    Regional anesthesia refers to the administration of anesthetic medication to a specific region of the body, such as a limb or a section of the spine. This type of anesthesia blocks the sensation of pain in the targeted area, while allowing the patient to remain awake and alert. Spinal and epidural anesthesia are both examples of regional anesthesia techniques. Spinal anesthesia involves injecting the anesthetic medication into the cerebrospinal fluid surrounding the spinal cord, while epidural anesthesia involves injecting the medication into the epidural space surrounding the spinal cord. Both techniques are commonly used for surgeries involving the lower abdomen, pelvis, and lower extremities.

    Rate this question:

  • 13. 

    Atropine may be used to

    • Relieve anxiety

    • Sedate

    • Reduce saliva

    • Reduce constipation

    Correct Answer
    A. Reduce saliva
    Explanation
    Atropine is a medication that belongs to a class of drugs called anticholinergics. It works by blocking the action of acetylcholine, a neurotransmitter that is responsible for various bodily functions. One of the effects of atropine is to reduce the production of saliva. This can be beneficial in certain medical conditions where excessive salivation is a problem, such as drooling or excessive sweating. By reducing saliva production, atropine can help alleviate these symptoms and improve the patient's comfort.

  • 14. 

    Ducosate and bisacodyl

    • Reduce vomiting

    • Reduce pain

    • Reduce constipation

    • Reduce abdominal distention

    Correct Answer
    A. Reduce constipation
    Explanation
    Ducosate and bisacodyl are medications commonly used to treat constipation. They work by different mechanisms to alleviate constipation symptoms. Ducosate is a stool softener that helps to increase water content in the stool, making it easier to pass. Bisacodyl, on the other hand, is a stimulant laxative that promotes bowel movements by increasing intestinal contractions. Therefore, the correct answer is "reduce constipation" as these medications are specifically indicated for this purpose.

    Rate this question:

  • 15. 

    Which of the following is a neuromuscular blockade?

    • Diazepam

    • Atropine

    • Midazolam

    • Succinylcholine

    Correct Answer
    A. Succinylcholine
    Explanation
    Succinylcholine is a neuromuscular blockade because it is a depolarizing muscle relaxant that acts by binding to the nicotinic acetylcholine receptors at the neuromuscular junction. This causes a sustained depolarization of the motor endplate, leading to muscle paralysis. Diazepam, atropine, and midazolam are not neuromuscular blockers, but rather belong to different drug classes. Diazepam is a benzodiazepine used for its sedative and anxiolytic effects, atropine is an anticholinergic agent used for its antispasmodic and anti-bradycardic effects, and midazolam is a short-acting benzodiazepine used for its sedative and amnestic properties.

  • 16. 

    Anethetics commonly used during dental or surgical procedures.

    • Topical

    • Local

    • Regional

    • General

    Correct Answer
    A. Local
    Explanation
    Local anesthetics are commonly used during dental or surgical procedures. These anesthetics are administered in a specific area or region of the body to numb the nerves and block the sensation of pain. Unlike general anesthesia, which affects the entire body and induces unconsciousness, local anesthesia allows the patient to remain awake and aware during the procedure while numbing the targeted area. This type of anesthesia is typically used for minor procedures or surgeries, such as dental fillings or small incisions, where localized pain relief is needed.

    Rate this question:

  • 17. 

    Diazepam, Midazolam, and Atropine are

    • Postoperative medications

    • Intraoperative medications

    • Preanesthetic medications

    • General anesthesia medications

    Correct Answer
    A. Preanesthetic medications
    Explanation
    Diazepam, Midazolam, and Atropine are classified as preanesthetic medications because they are commonly administered before surgery to prepare the patient for anesthesia. These medications help to induce relaxation, reduce anxiety, and prevent certain side effects associated with anesthesia. Preanesthetic medications are an important part of the anesthesia process as they help to ensure a smooth and safe transition into surgery.

    Rate this question:

  • 18. 

    Inhalation anesthetics may be in the form of volatile liquids, an example of which is

    • Halothane

    • Nitrous oxide

    Correct Answer
    A. Halothane
    Explanation
    Halothane is an example of a volatile liquid inhalation anesthetic. Volatile liquids are substances that easily evaporate at room temperature, allowing them to be inhaled as a gas. Halothane is commonly used for general anesthesia as it induces unconsciousness and provides muscle relaxation during surgical procedures. It has a low boiling point, making it easily vaporized and inhaled by the patient. Nitrous oxide, on the other hand, is a gas and not a volatile liquid, so it is not the correct answer in this case.

    Rate this question:

  • 19. 

    Nitrous oxide (laughing gas) has a MAC of 105, which makes it a very potent anesthetic for general surgery.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Nitrous oxide (laughing gas) does not have a MAC (Minimum Alveolar Concentration) of 105. MAC is a measure of the potency of an anesthetic, and a higher MAC value indicates a lower potency. In fact, nitrous oxide has a MAC of 105% and is considered a weak anesthetic. Therefore, the statement that it is a very potent anesthetic for general surgery is false.

    Rate this question:

  • 20. 

    Adverse reactions of local anesthetics include bradycardia, heart block, vasodilation.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Local anesthetics can have adverse reactions that include bradycardia (slow heart rate), heart block (interruption of electrical signals in the heart), and vasodilation (widening of blood vessels). These reactions can occur due to the effects of the anesthetic on the cardiovascular system. Therefore, the statement that adverse reactions of local anesthetics include bradycardia, heart block, and vasodilation is true.

    • Stage I

    • Stage II

    • Stage III

    • Stage IV

    Correct Answer
    A. Stage IV
    Explanation
    Stage IV, also known as Medullary Paralysis Stage, is the correct answer. This stage occurs as a result of an overdose and is characterized by the cessation of spontaneous respiration, depression of vital signs, and the possibility of death due to circulatory collapse.

    Rate this question:

  • 22. 

    There is an ideal anesthetic; that is, one that does everything.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement suggests that there exists an ideal anesthetic that can perform all functions. However, in reality, no single anesthetic can fulfill all requirements, as different patients have varying needs and reactions to anesthesia. Anesthesia is a complex field, and different types of anesthetics are used for different procedures and patients. Therefore, the statement is false.

    Rate this question:

    MAC or Minimum Alveolar Concentration is the minimum concentration in alveolar air that is anesthetic.  LOW MAC means

    • High potency

    • Low potency

    • Medium potency

    • Fair potency

    Correct Answer
    A. High potency
    Explanation
    A low MAC indicates that a small concentration of the anesthetic in the alveolar air is needed to produce anesthesia. This suggests that the anesthetic is highly potent, as even a small amount is effective in inducing anesthesia.

    Rate this question:

  • 24. 

    Diazepam may be used as

    • Relief of anxiety

    • Sedation

    • Reduction of saliva

    • Reduce constipation

    Correct Answer
    A. Relief of anxiety
    Explanation
    Diazepam is a medication that belongs to the class of benzodiazepines, which are commonly used to treat anxiety disorders. It works by enhancing the effects of a neurotransmitter called GABA in the brain, which helps to reduce feelings of anxiety and promote relaxation. Therefore, diazepam can be used to provide relief from anxiety symptoms.

    Rate this question:

  • 25. 

    Delirium Stage. Begins with loss of consciousness, irregular respiration occurs, vomiting, fecal and urinary incontinence may be some of the common adverse reactions

    • Stage I

    • Stage II

    • Stage III

    • Stage IV

    Correct Answer
    A. Stage II
    Explanation
    Stage II is the correct answer because it is the stage that follows the Delirium Stage. In this stage, the person has lost consciousness and may experience irregular respiration, vomiting, and loss of control over bowel and bladder function. This suggests that the adverse reactions mentioned in the question occur during Stage II.

    Rate this question:

  • 26. 

    Midazolam may be used as

    • Relief of anxiety

    • Sedation

    • Reduction of saliva

    • Reduction of constipation

    Correct Answer
    A. Sedation
    Explanation
    Midazolam is a benzodiazepine medication that is commonly used as a sedative. It works by enhancing the effects of a natural chemical in the body to promote relaxation and reduce anxiety. Sedation is the primary purpose of using midazolam, as it helps to induce sleepiness and calmness in patients. It is often used before medical procedures or surgeries to help patients relax and reduce any discomfort or anxiety they may experience. Therefore, the correct answer is sedation.

    First local anesthetic discovered in 1884

    • Amides

    • Esters

    • Procaine

    • Cocaine

    Correct Answer
    A. Cocaine
    Explanation
    Cocaine was the first local anesthetic discovered in 1884. It was initially used for its anesthetic properties, but its addictive nature and harmful side effects led to its replacement by safer alternatives. Cocaine is classified as an ester local anesthetic, which means it is derived from an ester compound. Despite its historical significance, cocaine is no longer used as a local anesthetic due to its potential for abuse and addiction.

    On Blood:Gas (Air in Lungs) Partition Coefficient.  Low coefficient indicates drug prefers

    • Blood

    • Gas

    Correct Answer
    A. Gas
    Explanation
    A low blood:gas partition coefficient indicates that the drug prefers the gas phase over the blood phase. This means that the drug has a higher solubility in the gas phase (such as in the lungs) compared to the blood. Therefore, it is more likely to stay in the gas phase and be eliminated through exhalation rather than getting absorbed into the bloodstream.

    Ketamine is

    • A general anesthetic agent

    • An intravenous anesthetic agent

    • An inhalant anesthetic

    • A dissociative anesthetic agent

    Correct Answer
    A. A dissociative anesthetic agent
    Explanation
    Ketamine is classified as a dissociative anesthetic agent. This means that it induces a state of dissociation, where the patient may feel detached from their surroundings and experience a sense of dissociation from their body. Ketamine is often used for its anesthetic properties during surgical procedures, as it can provide pain relief and induce a trance-like state. It is administered through various routes, including intravenous and inhalation, depending on the specific procedure and patient's needs.

    Cholinergics

    • Reduce nausea and vomiting

    • Reduce pain

    • Reduce abdominal distention

    • Reduce constipation

    Correct Answer
    A. Reduce abdominal distention
    Explanation
    Cholinergics are a type of medication that act on the cholinergic receptors in the body. These receptors are involved in various bodily functions, including the regulation of smooth muscle contractions in the gastrointestinal tract. By stimulating these receptors, cholinergics can help to enhance the movement of the intestines and reduce abdominal distention. This can be particularly beneficial for individuals who experience bloating or discomfort due to conditions such as irritable bowel syndrome or constipation. Therefore, the correct answer is that cholinergics reduce abdominal distention.

    Rate this question:

  • 35. 

    Which is not considered a neuroleptanalgetic agent?

    • Ketamine

    • Droperidol

    • Fentanyl

    Correct Answer
    A. Ketamine
    Explanation
    Ketamine is not considered a neuroleptanalgetic agent because it is primarily classified as a dissociative anesthetic. While it does have analgesic properties, it does not possess the typical neuroleptic effects seen in drugs like droperidol and fentanyl. Neuroleptanalgesia refers to the combination of a neuroleptic (antipsychotic) and an analgesic (painkiller), which produces sedation, pain relief, and amnesia. Ketamine, on the other hand, works by blocking NMDA receptors and inducing a dissociative state, making it unsuitable for neuroleptanalgesia.
