Correct Answer: A

Rationale: The correct answer is to monitor daily weight. Daily weight monitoring is crucial in assessing fluid balance in patients with heart failure because sudden weight gain can indicate fluid retention. Monitoring input and output (choice B) is important but may not provide a complete picture of fluid balance. Checking for edema (choice C) is a sign of fluid accumulation but may not be as accurate as daily weight monitoring. Monitoring blood pressure (choice D) is important in heart failure management but does not directly assess fluid balance.

Correct Answer: D

Rationale: The correct answer is to determine the pain level first. Assessing the client's pain is crucial before any procedure to ensure their comfort and safety. Applying skin preparation to wound edges (Choice A) may come later in the process after ensuring the client's comfort. Donning sterile gloves (Choice B) is important before directly handling the wound but can follow pain assessment. Normal saline (Choice C) might be used during wound cleansing but is not the initial step in this situation.

Correct Answer: D

Rationale: In a client with a history of angina experiencing chest pain radiating to the left arm, obtaining a 12-lead ECG is the priority action to assess for myocardial infarction. An ECG helps in diagnosing and evaluating the extent of cardiac ischemia or infarction. Administering nitroglycerin, oxygen, or aspirin can follow once the ECG has been performed to confirm the diagnosis and guide further interventions. Administering nitroglycerin sublingually is often appropriate for angina but should not precede the ECG in this urgent scenario. Oxygen therapy and aspirin administration are important interventions but obtaining the ECG takes precedence in assessing for acute cardiac events.

Correct Answer: C

Rationale: The correct answer is C because clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choices A, B, and D are incorrect. Choice A is not specific to metformin but rather a general recommendation for some medications. Choice B is a good practice for medication adherence but does not relate specifically to metformin. Choice D is inaccurate as weight gain is not an expected side effect of metformin.
