Correct Answer: A

Rationale: Muscle weakness is a characteristic finding in hyperkalemia. High levels of potassium can affect the normal function of muscles, leading to weakness. Nausea and increased thirst are not typically associated with hyperkalemia. Restlessness is more commonly seen in conditions such as hypoxia or anxiety, not specifically in hyperkalemia.

Correct Answer: D

Rationale: Administering analgesics on a scheduled basis for the first 24 hours is crucial to ensure adequate pain control in the immediate postoperative period. Choice A is incorrect because clear liquids are typically initiated gradually and advanced as tolerated but not specifically at 6 hours post-surgery. Choice B is incorrect as cromolyn nebulizer solution is not indicated for postoperative pain management in this scenario. Choice C is incorrect as applying a warm compress may not be appropriate for the operative site after appendicitis surgery and can potentially increase the risk of infection.

Correct Answer: C

Rationale: Regaining orientation to time and place is a realistic short-term goal for clients with delirium. It helps the individual become aware of their surroundings and current situation, aiding in reducing confusion and disorientation. Choice A is incorrect because the goal is focused on the client's understanding, not on explaining the experience of delirium. Choice B, resuming a normal sleep-wake cycle, may take longer than 2 to 3 days to achieve and is not directly related to regaining orientation. Choice D, establishing normal bowel and bladder function, is important but may not be a short-term goal specifically related to delirium.

Correct Answer: B

Rationale: The correct answer is B: 'Limit fluid intake to 1-2 liters per day.' For clients with heart failure, fluid restriction is essential to prevent fluid overload. Restricting fluid intake to 1-2 liters per day helps maintain fluid balance and prevents exacerbation of heart failure symptoms. Choices A, C, and D are incorrect because consuming 3 liters, 4 liters, or limiting water intake to 1 liter per day, respectively, can lead to fluid overload in clients with heart failure.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with chest pain because it helps relieve chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Assessing pain level, monitoring vital signs, and providing oxygen therapy are important interventions as well, but administering nitroglycerin takes precedence in addressing the immediate symptom of chest pain and potential cardiac ischemia.
