Correct Answer: A

Rationale: The correct intervention for a patient with hypokalemia is to administer potassium supplements and monitor the ECG. Potassium supplements help correct the low potassium levels in the body, while ECG monitoring is essential to detect any cardiac arrhythmias associated with hypokalemia. Choice B is incorrect because a high-sodium diet would worsen hypokalemia by further depleting potassium levels. Choice C is incorrect as it only focuses on monitoring symptoms and providing dietary education, but does not address the immediate need to correct potassium levels. Choice D is also incorrect as administering diuretics would exacerbate hypokalemia by increasing potassium loss.

Correct Answer: B

Rationale: The correct instruction for a client learning to use a cane is to maintain two points of support on the ground at all times. This ensures better stability and reduces the risk of falls. Choice A is incorrect because advancing the cane and the weaker leg simultaneously may lead to imbalance. Choice C is incorrect because the cane should be used on the stronger side to provide support. Choice D is incorrect because there is no specific measurement for advancing the cane with each step, and the focus should be on maintaining stability.

Correct Answer: B

Rationale: Administering insulin before meals as prescribed is crucial for a client with diabetes being discharged because it ensures proper blood sugar control. Choice A is incorrect because insulin should not be taken only when feeling unwell; it should be taken as prescribed. Choice C is incorrect as monitoring blood sugar levels weekly may not provide timely adjustments to insulin doses. Choice D is incorrect as checking blood sugar only once in the morning is not sufficient for proper diabetes management.

Correct Answer: B

Rationale: The correct answer is B: Hypervigilance. Individuals with PTSD often experience hypervigilance, which involves being overly alert, easily startled, and constantly scanning their environment for potential threats. This heightened state of awareness is a common response to the trauma experienced. Choices A, C, and D are incorrect. Hyperactivity is not typically a primary manifestation of PTSD; restlessness may occur but is not as characteristic as hypervigilance, and although avoidance of social situations can be a symptom of PTSD, hypervigilance is more directly associated with the disorder.

Correct Answer: A

Rationale: The correct answer is A: Crush medications and mix with food. When administering oral medications to a patient with dysphagia, crushing the medications and mixing them with food is a common method to aid in swallowing. Choice B is incorrect because using a straw could pose a choking hazard for patients with dysphagia. Choice C is incorrect as thickened liquids may not always be suitable for all medications. Choice D is incorrect because having the patient lie flat can increase the risk of aspiration, which is not recommended for patients with dysphagia.
