The nurse teaches the patient receiving propranolol (Inderal) at home for management of ventricular arrhythmias to monitor what parameter?
- A. Weekly pulse.
- B. Daily fluid intake.
- C. Daily blood pressure.
- D. Weekly weight.
Correct Answer: C
Rationale: The correct answer is C: Daily blood pressure. Monitoring daily blood pressure is crucial for a patient taking propranolol for ventricular arrhythmias as it helps assess the effectiveness of the medication in controlling the arrhythmias and ensuring the patient's safety. Changes in blood pressure can indicate potential side effects or worsening of the condition. Monitoring pulse alone (choice A) may not provide a comprehensive picture of the cardiac status. Daily fluid intake (choice B) and weekly weight (choice D) are not specific parameters for monitoring the effects of propranolol on ventricular arrhythmias.

When taking a medication history on a patient, why should the nurse ask about complementary or alternative therapies?
- A. Many drug alternative therapy interactions can cause serious problems.
- B. Natural products may be more effective, and the prescribed drugs may not be needed.
- C. Patients starting on new drugs are usually not compliant with medical regimes.
- D. The cost of the drug and the alternative therapy may be too expensive for the patient to handle.
Correct Answer: A
Rationale: The correct answer is A because many complementary or alternative therapies can interact with prescribed medications, leading to serious adverse effects or reduced efficacy. By asking about these therapies, the nurse can identify potential interactions and prevent harm to the patient. Choice B is incorrect because natural products can also have interactions and may not always be more effective. Choice C is irrelevant to the question as it pertains to medication adherence, not interactions. Choice D focuses on cost, which is not directly related to the potential harm from interactions.
The nursing instructor asks the student nurse to explain the action of sumatriptan. What is the student's best response?
- A. Vasodilation of peripheral blood vessels.
- B. Depresses pain response in the central nervous system.
- C. Vasoconstrictive on cranial blood vessels.
- D. Binds to acetylcholine receptors to prevent nerve transmission.
Correct Answer: C
Rationale: The correct answer is C: Vasoconstrictive on cranial blood vessels. Sumatriptan is a medication used to treat migraines by constricting blood vessels in the brain, which helps to reduce inflammation and pain associated with migraines. This action helps to alleviate migraine symptoms. Choices A, B, and D are incorrect because sumatriptan does not cause vasodilation, depress pain response in the central nervous system, or bind to acetylcholine receptors. Sumatriptan specifically targets cranial blood vessels to relieve migraine symptoms.
What is the action of the thiazide diuretic?
- A. Blocks the sodium pump.
- B. Block the chloride pump.
- C. Blocks the carbonic anhydrase pump.
- D. Blocks the potassium pump.
Correct Answer: B
Rationale: The correct answer is B: Blocks the chloride pump. Thiazide diuretics inhibit the sodium-chloride symporter in the distal convoluted tubule of the nephron, leading to increased excretion of sodium and chloride ions, resulting in diuresis. Choice A is incorrect as thiazides do not block the sodium pump. Choice C is incorrect as carbonic anhydrase inhibitors, not thiazides, block the carbonic anhydrase enzyme. Choice D is incorrect as thiazides do not block the potassium pump.
A student asks the pharmacology instructor to explain the action of anticholinergic agents. What would be the instructor's best response?
- A. They compete with serotonin for muscarinic acetylcholine receptor sites.
- B. They increase norepinephrine at the neuromuscular junction.
- C. They block nicotinic receptors.
- D. They act to block the effects of the parasympathetic nervous system.
Correct Answer: D
Rationale: The correct answer is D: They act to block the effects of the parasympathetic nervous system. Anticholinergic agents inhibit the action of acetylcholine, the primary neurotransmitter of the parasympathetic nervous system. By blocking muscarinic acetylcholine receptors, these agents reduce parasympathetic stimulation, leading to effects such as decreased salivation, decreased GI motility, and pupil dilation.
Choice A is incorrect because anticholinergic agents do not compete with serotonin for receptor sites; they primarily target acetylcholine receptors. Choice B is incorrect as anticholinergic agents do not directly affect norepinephrine levels at the neuromuscular junction. Choice C is incorrect because anticholinergic agents primarily target muscarinic receptors, not nicotinic receptors.
The nurse evaluates an improvement in the patient's heart failure (HF) status based on what assessment finding?
- A. Improved mental status.
- B. Using fewer pillows at night.
- C. Increased skin turgor.
- D. Heart rate regular.
Correct Answer: B
Rationale: The correct answer is B: Using fewer pillows at night. This indicates decreased fluid retention, a common symptom of heart failure. Improved mental status (A) may not directly correlate with HF improvement. Increased skin turgor (C) is more related to dehydration. A regular heart rate (D) is a positive sign but not specific to HF improvement.
