Correct Answer: A

Rationale: The correct answer is A. Doxazosin can cause first-dose orthostatic hypotension, which may lead to dizziness or fainting when the client stands up too quickly. The nurse should advise the client to change positions slowly and lie down if dizziness occurs to prevent falls and other injuries. Choice B is incorrect because while the client can continue normal activities, caution should be taken with position changes. Choice C is incorrect as doxazosin does not interact with dairy products. Choice D is incorrect as there is no need to avoid green leafy vegetables specifically while taking doxazosin.

Correct Answer: A

Rationale: The correct answer is A: Third trimester of pregnancy. Salicylic acid is contraindicated during the third trimester of pregnancy due to the risk of complications for both the mother and the fetus. Thrombocytopenia (choice B) is not a contraindication to salicylic acid therapy. Coronary artery disease (choice C) is not a specific contraindication to salicylic acid therapy. However, caution should be exercised in patients with coronary artery disease due to the antiplatelet effects of salicylic acid. Adolescents with chickenpox (choice D) should not be given salicylic acid due to the risk of Reye Syndrome, a rare but serious illness.

Correct Answer: D

Rationale: Monitoring blood pressure, weight, and heart rhythm is crucial in clients with a history of heart disease as these parameters can indicate changes in the cardiovascular status. Changes in blood pressure can signify heart strain, weight fluctuations can be related to fluid retention or heart failure, and irregular heart rhythm can indicate arrhythmias or other cardiac issues. Monitoring all these parameters comprehensively allows for early detection of potential complications and timely intervention. Therefore, selecting 'All of the above' is the correct choice as it encompasses all the essential parameters for monitoring in clients with heart disease. Choices A, B, and C are incorrect as monitoring only one or two of these parameters may lead to missing important changes in the client's condition.

Correct Answer: A

Rationale: Corrected Rationale: Metformin should be taken with food to minimize gastrointestinal side effects. Choice A is the correct answer as taking metformin with meals can help reduce the likelihood of experiencing gastrointestinal side effects like diarrhea and nausea, which are common side effects of metformin. Choice B is incorrect because metformin actually helps lower blood sugar levels and does not cause hyperglycemia. Choice C is incorrect as metformin is usually taken twice or even three times a day, not just once daily. Choice D is incorrect because metformin is an oral medication, not an injectable one.

Correct Answer: C

Rationale: The correct answer is C: Administer insulin glargine once daily at bedtime. Insulin glargine is a long-acting insulin that provides a basal level of insulin throughout the day. It should be given at the same time each day, usually at bedtime, to maintain a consistent blood sugar level. Choices A, B, and D are incorrect. Injecting insulin glargine before a meal (Choice A) is not necessary as it is a long-acting insulin. Shaking the insulin vial (Choice B) is not recommended as it may cause bubbles to form, affecting the accuracy of the dose. Taking insulin glargine with short-acting insulin (Choice D) is not a typical practice as insulin glargine is used for basal insulin coverage.
