Correct Answer: B

Rationale: The correct lifestyle change that should be emphasized for a client with hypertension is to reduce caffeine and sodium intake. Caffeine can temporarily raise blood pressure, and high sodium intake is linked to increased blood pressure levels. Therefore, reducing these two components can help manage blood pressure in individuals with hypertension. Choices A, C, and D are incorrect because increasing intake of dairy products, consuming carbohydrate-rich meals, and limiting intake of leafy green vegetables do not specifically address the factors that contribute to high blood pressure in hypertension.

Correct Answer: A

Rationale: The correct answer is A: Clean the perineal area with soap and water. This step is essential in preventing infection and promoting hygiene. Using antiseptic wipes (choice B) is not a standard practice for perineal care; soap and water are preferred. While patting the area dry after cleaning (choice C) is important, the initial step of cleaning with soap and water is crucial. Using gloves (choice D) is a good practice to prevent the spread of infection, but it is not the initial step in providing perineal care.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with hypertension involve monitoring blood pressure and educating the patient about lifestyle changes. These interventions help in managing hypertension by keeping track of the patient's blood pressure readings and empowering them with knowledge to make lifestyle modifications such as adopting a healthy diet, regular exercise, stress management, and avoiding smoking and excessive alcohol consumption. Administering antihypertensive medications (choice B) is typically done by a healthcare provider rather than a nurse. While regular monitoring of blood pressure (choice C) is important, administering diuretics is a specific medical intervention that should be prescribed by a healthcare provider. Monitoring blood glucose (choice D) is more relevant for patients with diabetes rather than hypertension.

Correct Answer: B

Rationale: The correct answer is to investigate the client's recent medication changes. In a client with dementia who frequently becomes agitated, medication changes can often be a significant factor contributing to their behavior. Checking recent medication changes can help identify if any specific medication is causing or exacerbating the agitation. Choice A about fluid and electrolyte balance is less likely to be the priority unless there are specific indications in the medical record. Choice C, investigating recent changes in cognitive functioning, may be important but addressing the agitation first is a more immediate concern. Choice D, investigating the client's psychosocial environment, is also important but may not directly address the immediate cause of the agitation as medication changes could.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Hypokalemia is an adverse effect of digoxin. Digoxin can cause hypokalemia, which increases the risk of toxicity. Monitoring potassium levels is crucial when a client is taking digoxin. Choices B, C, and D are incorrect as hypernatremia, hypertension, and tachycardia are not directly associated with digoxin use.
