Correct Answer: B

Rationale: The correct answer is lack of sleep (choice B). In acute mania, lack of sleep can exacerbate symptoms, lead to exhaustion, and pose serious risks to the client's well-being. Addressing the client's sleep deprivation is a priority as it can impact their overall health and recovery. Increased speech (choice A) and agitation (choice C) are common in acute mania but do not pose immediate physical risks like lack of sleep. Poor concentration (choice D) is also a symptom of acute mania but addressing sleep deprivation takes precedence due to its severe consequences.

Correct Answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.

Correct Answer: B

Rationale: The correct answer is to reduce caffeine and alcohol intake for a client with hypertension. Caffeine and alcohol can increase blood pressure, so reducing their intake can help manage hypertension. Increasing sodium intake (Choice A) is not recommended for hypertension as it can lead to fluid retention and increased blood pressure. Eating carbohydrate-rich meals (Choice C) is also not ideal as excessive carbohydrates can contribute to weight gain, which can worsen hypertension. Similarly, increasing protein intake (Choice D) is not a primary focus for managing hypertension unless a specific protein deficiency is present.

Correct Answer: B

Rationale: The correct intervention for a client with a chest tube connected to a closed drainage system is to maintain the drainage below the level of the chest. This position allows proper drainage of fluids and helps prevent complications such as backflow of blood or fluids into the chest cavity. Clamping the chest tube (Choice A) is incorrect as it can lead to a tension pneumothorax. Elevating the chest tube above chest level (Choice C) is also incorrect because it can impede proper drainage. Avoiding frequent dressing changes (Choice D) is important to prevent introducing infection, but it is not directly related to the position of the drainage system.

Correct Answer: B

Rationale: The most appropriate response when a client with chronic kidney disease asks about fluid restrictions is to inform them that limiting fluid intake may be necessary to prevent fluid overload. This is crucial in managing the condition and preventing complications such as edema and electrolyte imbalances. Choice A is incorrect as fluid restrictions are commonly advised for clients with chronic kidney disease. Choice C is partially correct as fluid restrictions are indeed based on lab results and daily weights, but the primary goal is to prevent fluid overload. Choice D is incorrect because fluid restrictions are not limited to just during dialysis; they are often recommended throughout the day to manage the condition.
