Which of the following can also be used to treat acetaminophen toxicity?
- A.
Atropine
- B.
Codeine
- C.
Guaifenesin
- D.
Acetylcysteine
Correct Answer
D. AcetylcysteineExplanation
Acetylcysteine can also be used to treat acetaminophen toxicity. Acetaminophen is a commonly used pain reliever, but in overdose, it can cause liver damage. Acetylcysteine helps to prevent or reduce liver damage by replenishing glutathione, a substance that is depleted during acetaminophen overdose. It acts as an antioxidant and helps to neutralize the toxic byproducts of acetaminophen metabolism. Therefore, acetylcysteine is an effective treatment for acetaminophen toxicity.Rate this question:

Which of the following is an Antitussive?
- A.
Yohimbine
- B.
Trimeprazine
- C.
Theophylline
- D.
Albuterol
Correct Answer
B. TrimeprazineExplanation
Trimeprazine is an antitussive, which means it is a medication used to suppress or relieve coughing. It works by blocking the cough reflex in the brain, helping to reduce the frequency and intensity of coughing. Yohimbine is not an antitussive; it is primarily used for erectile dysfunction. Theophylline is a bronchodilator used to treat asthma and other respiratory conditions, while Albuterol is also a bronchodilator commonly used to relieve symptoms of asthma and chronic obstructive pulmonary disease (COPD).Rate this question:

Which of the following is not a type of Bronchodilator?
- A.
Beta-Adrenergic-Agonist
- B.
Anticholinergic
- C.
Antihistamine
- D.
Methylxanthine
Correct Answer
C. AntihistamineExplanation
Antihistamines are not a type of bronchodilator. Bronchodilators are medications that relax and widen the airways in the lungs, making it easier to breathe. Beta-Adrenergic-Agonists, Anticholinergics, and Methylxanthines are all types of bronchodilators commonly used to treat conditions such as asthma and chronic obstructive pulmonary disease (COPD). Antihistamines, on the other hand, are primarily used to relieve allergy symptoms by blocking the effects of histamine, a substance released by the immune system during an allergic reaction. While they may help with symptoms such as sneezing and itching, they do not directly affect the airways and are not considered bronchodilators.Rate this question:

Which of the following drugs block Acetylcholine in order to prevent bronchoconstriction?
- A.
Aminopentamide
- B.
Theobromine
- C.
Naloxone
- D.
Phenylephrine
Correct Answer
A. AminopentamideExplanation
Aminopentamide is the correct answer because it blocks the action of acetylcholine, which is responsible for bronchoconstriction. By inhibiting acetylcholine, aminopentamide helps to prevent the narrowing of the airways in the lungs, thereby relieving symptoms of bronchoconstriction. Theobromine, naloxone, and phenylephrine do not have this specific mechanism of action and therefore would not be effective in preventing bronchoconstriction.Rate this question:

Which of the following drugs is a respiratory stimulant?
- A.
Hydrocodone
- B.
Atropine
- C.
Aminophylline
- D.
Doxapram
Correct Answer
D. DoxapramExplanation
Doxapram is a respiratory stimulant. It acts on the central nervous system to increase the respiratory rate and depth, making it useful in treating respiratory depression caused by drug overdose, anesthesia, or other conditions. Hydrocodone is an opioid analgesic, Atropine is an anticholinergic drug, and Aminophylline is a bronchodilator. None of these drugs have respiratory stimulant properties.Rate this question:

Which of the following suppresses the cough reflex in the brain?
- A.
Theophylline
- B.
Doxapram
- C.
Guaifenesin
- D.
Trimeprazine
Correct Answer
D. TrimeprazineExplanation
Trimeprazine is the correct answer because it is an antitussive medication that suppresses the cough reflex in the brain. It works by blocking the action of certain chemicals in the brain that trigger the cough reflex, thereby reducing coughing. Theophylline is a bronchodilator and does not directly suppress the cough reflex. Doxapram is a respiratory stimulant and Guaifenesin is an expectorant, both of which do not suppress the cough reflex.Rate this question:

Which of the following drugs should you use in an emergency situation with a patient in ANAPHYLACTIC SHOCK?
- A.
Epinephrine
- B.
Atropine
- C.
Diphenhydramine
- D.
Doxapram
Correct Answer
A. EpinephrineExplanation
Epinephrine is the drug of choice in an emergency situation with a patient in anaphylactic shock. Anaphylactic shock is a severe and potentially life-threatening allergic reaction that can cause difficulty in breathing, low blood pressure, and loss of consciousness. Epinephrine works by constricting blood vessels, increasing heart rate, and opening up the airways, which helps to reverse the symptoms of anaphylaxis and improve the patient's condition. Atropine, Diphenhydramine, and Doxapram are not typically used in the treatment of anaphylactic shock.Rate this question:

Which of the following can also be used as a muscle relaxant for horses?
- A.
Codeine
- B.
Guaifenesin
- C.
Atropine
- D.
Doxapram
Correct Answer
B. GuaifenesinExplanation
Guaifenesin can also be used as a muscle relaxant for horses. Guaifenesin is an expectorant commonly used in humans to help loosen and clear mucus from the airways. However, it can also have muscle relaxant properties when used in higher doses. In horses, guaifenesin is sometimes used as a muscle relaxant during surgical procedures or to help alleviate muscle spasms or stiffness. It works by acting on the central nervous system and reducing muscle tone.Rate this question:

Which of the following is used to reverse opioids?
- A.
Naloxone
- B.
Pseudoephedrine
- C.
Aminophylline
- D.
Terbutaline
Correct Answer
A. NaloxoneExplanation
Naloxone is used to reverse opioids. It is an opioid receptor antagonist that works by binding to the same receptors as opioids, blocking their effects and reversing the respiratory depression and sedation caused by opioids. Naloxone is commonly used in emergency situations to treat opioid overdoses and can quickly restore normal breathing and consciousness. It is an important tool in combating the potentially life-threatening effects of opioid overdose.Rate this question:

Which of the following drugs stimulates Beta-2 receptors, causing bronchodilation?
- A.
Acetylcysteine
- B.
Yohimbine
- C.
Chlorpheniramine
- D.
Albuterol
Correct Answer
D. AlbuterolExplanation
Albuterol is the correct answer because it is a drug that specifically stimulates Beta-2 receptors, resulting in bronchodilation. Bronchodilation is the widening of the airways in the lungs, which helps to relieve symptoms of conditions such as asthma and chronic obstructive pulmonary disease (COPD). Acetylcysteine is a mucolytic agent used to break down and thin mucus, Yohimbine is an alpha-2 adrenergic antagonist, and Chlorpheniramine is an antihistamine. None of these drugs have the specific mechanism of action of stimulating Beta-2 receptors to cause bronchodilation.Rate this question:

All of the following are classified as the Upper Respiratory tract except
- A.
Nares
- B.
Alveoli
- C.
Larynx
- D.
Pharynx
Correct Answer
B. AlveoliExplanation
The alveoli are not classified as part of the Upper Respiratory tract because they are located in the lungs, which are part of the Lower Respiratory tract. The Upper Respiratory tract consists of the nares (nostrils), pharynx, and larynx, which are involved in the passage of air from the external environment to the lower respiratory system. The alveoli, on the other hand, are tiny air sacs within the lungs where gas exchange takes place between the air and the bloodstream.Rate this question:

What is the function of Goblet cells?
- A.
Gas exchange
- B.
Secrete mucus to trap foreign body
- C.
Move foreign debris out of the upper respiratory tract
- D.
Tertiary level of the respiratory tree
Correct Answer
B. Secrete mucus to trap foreign bodyExplanation
Goblet cells are specialized cells found in the respiratory tract and other mucous membranes. Their main function is to secrete mucus, a sticky substance that helps to trap and remove foreign particles, such as dust, bacteria, and other pathogens. This mucus acts as a protective barrier, preventing these particles from entering further into the respiratory system and causing harm. Therefore, the function of goblet cells is to secrete mucus to trap foreign bodies and maintain the health of the respiratory system.Rate this question:
-

Ventilation is
- A.
Breathing in a foreign body
- B.
Actual exchange in the gas
- C.
Breathing in fresh air
- D.
Collapse of alveoli
Correct Answer
C. Breathing in fresh airExplanation
Ventilation refers to the process of breathing in fresh air. It involves the inhalation of oxygen-rich air and the exhalation of carbon dioxide. This exchange of gasses is essential for the proper functioning of the respiratory system and the delivery of oxygen to the body's cells. Breathing in fresh air helps to replenish oxygen levels in the body and remove waste gasses.Rate this question:

What is important to note when using Methylxanthines?
- A.
Narrow therapeutic index
- B.
Reverse analgesia
- C.
Contraindicated for hypertension and tachycardia
- D.
Can treat acetaminophen toxicity
Correct Answer
A. Narrow therapeutic indexExplanation
Methylxanthines have a narrow therapeutic index, which means that the difference between a therapeutic dose and a toxic dose is small. This implies that careful monitoring of the drug's concentration in the blood is necessary to avoid toxicity. The other options mentioned, such as reverse analgesia, contraindication for hypertension and tachycardia, and treatment of acetaminophen toxicity, are not directly related to the important note about the narrow therapeutic index of Methylxanthines.Rate this question:

What is important to note when using Phenylephrine?
- A.
Narrow therapeutic index
- B.
Reverse analgesia
- C.
Contraindicated for hypertension and tachycardia
- D.
Can treat acetaminophen toxicity
Correct Answer
C. Contraindicated for hypertension and tachycardiaExplanation
Phenylephrine is a medication commonly used as a decongestant and to raise blood pressure in certain situations. However, it is important to note that it is contraindicated, or not recommended, for use in patients with hypertension (high blood pressure) and tachycardia (rapid heart rate). This is because Phenylephrine can further increase blood pressure and heart rate, potentially worsening these conditions. Therefore, caution should be exercised and alternative medications should be considered in patients with hypertension and tachycardia.Rate this question:
