Pharmacology of Drugs Acting on Cardiovascular System Questions
Question 1 of 5
The nurse is reviewing the food choices of a patient who is taking a monoamine oxidase inhibitor (MAOI). Which food choice would indicate the need for additional teaching?
Correct Answer: C
Rationale: The correct answer is C: Salami and Swiss cheese sandwich. This is because salami and Swiss cheese are high in tyramine, which can cause a hypertensive crisis in patients taking MAOIs due to their inhibitory effect on monoamine oxidase. Orange juice (A) does not contain tyramine. Fried eggs over-easy (B) and biscuits with honey (D) are also safe choices as they do not contain high levels of tyramine. Therefore, the need for additional teaching is indicated by the selection of foods high in tyramine like salami and Swiss cheese.
Question 2 of 5
The nurse is reviewing the use of antitussive drugs. Antitussive drugs would be most appropriate for which patient?
Correct Answer: D
Rationale: The correct answer is D because antitussive drugs are used to suppress coughing. In the case of a patient who has developed bronchitis 2 days after abdominal surgery, coughing can be painful and may strain the surgical site. Therefore, using antitussive drugs to reduce the coughing can help prevent complications and promote healing post-surgery. A, B, and C are incorrect: A: Antitussive drugs are not appropriate for a patient with pneumonia and productive cough because coughing helps clear the airways of excess mucus. B: Antitussive drugs are not suitable for a patient with a tracheostomy and thick mucus secretions as coughing helps clear the secretions and prevent infections. C: Antitussive drugs are not indicated for a patient with a productive cough for 2 weeks as this may be a sign of an underlying condition that needs to be addressed rather than suppressed.
Question 3 of 5
Parenteral administration:
Correct Answer: C
Rationale: Parenteral administration usually produces a more rapid response than oral administration because the medication bypasses the digestive system and is directly absorbed into the bloodstream. This route includes injections, intravenous infusions, and intramuscular injections, allowing for quicker onset of action. Option A is incorrect as parenteral administration can be used in unconscious patients. Option B is incorrect as parenteral administration can provide more accurate dosages. Option D is incorrect as parenteral administration is actually preferred in emergency situations due to its rapid effects.
Question 4 of 5
Tachyphylaxis is:
Correct Answer: B
Rationale: Tachyphylaxis refers to a rapid decrease in response to a drug upon repeated or continuous administration. The correct answer is B because it specifically mentions "very rapidly developing tolerance," which accurately describes tachyphylaxis. Option A is incorrect because tachyphylaxis is not related to drug interactions. Option C is incorrect because tachyphylaxis is characterized by a quick onset of decreased responsiveness, not taking days or weeks to develop. Option D is incorrect as tachyphylaxis is a recognized phenomenon in pharmacology.
Question 5 of 5
Indicate the local anesthetic, which is mainly used for regional nerve block anesthesia:
Correct Answer: B
Rationale: The correct answer is B: Tetracaine. Tetracaine is a long-acting local anesthetic commonly used for regional nerve block anesthesia due to its duration of action. It provides effective and prolonged pain relief in a specific area by blocking nerve conduction. Procaine (A) is a short-acting local anesthetic, making it less suitable for regional nerve block anesthesia. Bupivacaine (D) is a long-acting local anesthetic like tetracaine, but it is more commonly used for epidural or spinal anesthesia rather than regional nerve blocks. Therefore, tetracaine is the most appropriate choice for regional nerve block anesthesia among the options provided.
