Question 1 of 5
A client with chronic stable angina is prescribed nitroglycerin (Nitrostat) for chest pain. The nurse should include which instruction when teaching the client about this medication?
Correct Answer: A
Rationale: The correct instruction when teaching a client about nitroglycerin (Nitrostat) is to take it at the first sign of chest pain. Nitroglycerin works rapidly to dilate blood vessels, improving blood flow to the heart muscle. Taking it promptly can help alleviate symptoms quickly and prevent the condition from worsening. Choice B is incorrect because nitroglycerin is usually taken sublingually (under the tongue) and not swallowed. Choice C is incorrect because nitroglycerin is not typically taken with meals. Choice D is incorrect because nitroglycerin should be stored in its original container away from heat and light.
Question 2 of 5
A client with hypertension is prescribed a thiazide diuretic. What instruction should the nurse reinforce to the client?
Correct Answer: C
Rationale: The correct answer is to weigh oneself daily. This instruction is important as daily weights help monitor fluid loss and are crucial for detecting early signs of fluid imbalance when taking a diuretic. Weighing daily allows for timely adjustments in treatment and helps prevent complications associated with fluid imbalance. Choice A is not directly related to the client's need for monitoring fluid balance. Choice B, although important for some diuretics, is not specific to thiazide diuretics. Choice D is not appropriate as limiting fluid intake without proper monitoring can lead to dehydration, especially when taking diuretics.
Question 3 of 5
The client with chronic stable angina is prescribed a beta blocker. The nurse is reinforcing instructions. What instruction should the nurse include?
Correct Answer: B
Rationale: The correct instruction for the nurse to include is to advise the client to report a pulse rate below 60 beats per minute. Beta blockers are known to lower heart rate, and a pulse rate below 60 beats per minute may indicate bradycardia, a condition that requires medical attention. Option A, 'Take the medication with a meal,' is incorrect because beta blockers don't necessarily need to be taken with food. Option C, 'Discontinue the medication if dizziness occurs,' is incorrect because abrupt cessation of beta blockers can lead to rebound hypertension and other adverse effects. Option D, 'Avoid drinking grapefruit juice,' is unrelated to beta blockers' mechanism of action or side effects.
Question 4 of 5
The healthcare provider is reinforcing teaching for a client who is starting statin therapy. Which dietary advice should the healthcare provider give?
Correct Answer: C
Rationale: The correct answer is C: Avoid grapefruit and grapefruit juice. Grapefruit and grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. It is crucial for clients on statin therapy to avoid grapefruit products to ensure the medication's effectiveness and safety. Choices A, B, and D are incorrect because they do not directly impact the metabolism or effectiveness of statin therapy.
Question 5 of 5
The client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?
Correct Answer: B
Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor the effectiveness of anticoagulant therapy, especially with heparin. A prolonged aPTT indicates effective anticoagulation, reducing the risk of further clot formation in the client with deep vein thrombosis (DVT). The other options, such as complete blood count (CBC), serum electrolytes, and liver function tests, do not directly assess the therapeutic effectiveness of anticoagulant therapy. Therefore, the correct answer is B.
