Pharmacology of Drugs Acting on Cardiovascular System Questions
Question 1 of 5
The nurse administers a medication that potentiates the action of GAB Which effect would be expected?
Correct Answer: A
Rationale: The correct answer is A: Reduced anxiety. GABA is an inhibitory neurotransmitter in the brain that helps reduce neuronal excitability. By potentiating its action, the medication would enhance its calming effect, resulting in reduced anxiety. Choice B (Enhanced memory) is incorrect as GABA primarily affects anxiety and not memory. Choice C (Disorganized thinking) is incorrect as GABA's role is not related to cognitive processes. Choice D (Sensory perceptual alterations) is incorrect as GABA modulation does not typically lead to changes in sensory perception.
Question 2 of 5
An 18-year-old basketball player fell and twisted his ankle during a game. The nurse will expect to administer which type of analgesic?
Correct Answer: D
Rationale: The correct answer is D: Nonopioid analgesic, such as indomethacin (Indocin). Given the ankle injury, nonopioid analgesics like indomethacin are appropriate for managing pain as they target inflammation and reduce pain without the risk of opioid-related side effects. Synthetic opioids (A) and opium alkaloids (B) are not typically indicated for mild to moderate pain like an ankle twist. Opioid antagonists (C) like naloxone are used to reverse opioid overdose, not for pain relief. In this case, the nonopioid analgesic is the most suitable choice for managing the player's pain effectively.
Question 3 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 4 of 5
A patient will be discharged on quinidine sulfate (Quinidex) extended-release tablets for the treatment of ventricular ectopy. The nurse will include which information in the teaching plan?
Correct Answer: B
Rationale: The correct answer is B: Signs of cinchonism, such as tinnitus, loss of hearing, or slight blurring of vision, may occur. Cinchonism is a potential side effect of quinidine sulfate, characterized by symptoms like tinnitus, loss of hearing, and blurred vision. It is essential for the nurse to educate the patient about these potential adverse effects to ensure early recognition and prompt reporting to the healthcare provider. This information is crucial for monitoring the patient's response to the medication and preventing further complications. Incorrect choices: A: The medication should not be stopped abruptly, and it is important to complete the prescribed course even if symptoms subside to prevent recurrence. C: While photosensitivity can be a side effect of some medications, it is not specifically associated with quinidine sulfate. It is not a priority teaching point for this medication. D: Seeing the tablet in the stool does not necessarily indicate treatment failure or danger. It is more likely due to the extended
Question 5 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.
