Correct Answer: A

Rationale: The correct next action for the nurse to take is to check for orthostatic hypotension. This step is crucial as it ensures the client's safety during the transfer process. Orthostatic hypotension is a drop in blood pressure that can occur when a person moves from a lying down position to a sitting or standing position. By checking for orthostatic hypotension before transferring the client, the nurse can prevent potential complications such as dizziness, lightheadedness, or falls. Choices B, C, and D are incorrect in this scenario as they do not address the immediate safety concern of assessing for orthostatic hypotension.

Correct Answer: A

Rationale: The correct answer is A: Potassium level. Hypokalemia increases the risk of digoxin toxicity. Digoxin can potentiate the effects of low potassium levels, leading to life-threatening arrhythmias. Therefore, it is essential to review the patient's potassium level before administering digoxin. Choices B, C, and D are incorrect because calcium level, hemoglobin level, and white blood cell count are not directly related to the risk of digoxin toxicity.

Correct Answer: C

Rationale: The correct answer is C. When using brimonidine to treat open-angle glaucoma, patients may experience temporary irritation in the eyes. Choice A is incorrect because vision improvement from brimonidine is not immediate. Choice B is incorrect as brimonidine should be used as prescribed, not just when eyes are irritated. Choice D is important but does not directly indicate an understanding of the medication's use.

Correct Answer: B

Rationale: The essential question during screening for alcohol use disorder is asking about blackouts or loss of consciousness, which can be indicative of excessive drinking and related to alcohol use disorder. Choices A, C, and D are not as directly related to screening for alcohol use disorder. Employment status (Choice A) is not a primary question in alcohol use disorder screening. Sleep quality (Choice C) and family history of substance use (Choice D) may be relevant but are not as crucial as inquiring about blackouts or loss of consciousness.

Correct Answer: A

Rationale: The correct answer is A: Increased shortness of breath. In COPD, worsening symptoms often include increased shortness of breath due to impaired lung function. This indicates a decline in respiratory status and the need for prompt intervention. Choice B, decreased wheezing, is not indicative of worsening COPD as it could suggest better airflow. Choice C, productive cough with green sputum, may indicate an infection but not necessarily worsening COPD. Choice D, a slight increase in fatigue, is non-specific and may not directly correlate with the worsening of COPD.
