What are the risk factors for developing pneumonia in older adults?

Correct Answer: A

Rationale: The correct answer is A: Immobility and decreased lung function. Older adults with immobility and decreased lung function are at a higher risk of developing pneumonia. Immobility can lead to decreased lung expansion and impaired clearance of secretions, predisposing to pneumonia. While poor hygiene, aspiration, use of respiratory equipment, medications, poor nutritional status, and compromised immune system can also contribute to pneumonia risk, they are not as directly associated with pneumonia in older adults as immobility and decreased lung function.

Correct Answer: A

Rationale: The correct answer is A: Monitor for signs of infection and administer pain relief. In postoperative care for a patient with a hip replacement, it is crucial for the nurse to monitor for signs of infection, such as increased pain, redness, swelling, or drainage from the surgical site. Administering pain relief is also important to ensure the patient's comfort and aid in their recovery. Choices B, C, and D are incorrect as they do not directly relate to the immediate postoperative care needs of a patient with a hip replacement. Ensuring a low-calcium diet, using crutches, or monitoring for deep vein thrombosis are not primary responsibilities in the immediate postoperative period for this type of surgery.

Correct Answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A. Administering glucose or dextrose is a crucial nursing intervention for a patient experiencing hypoglycemia as it helps to quickly raise blood sugar levels. Monitoring blood sugar levels is essential to ensure that the patient's glucose levels normalize. Choice B is incorrect because providing a high-carbohydrate snack may not be sufficient to rapidly raise blood sugar levels in severe hypoglycemia. Choice C is incorrect because while monitoring for sweating and confusion is important in hypoglycemia, it is not a direct nursing intervention. Choice D is incorrect as providing insulin would lower blood sugar levels further, worsening hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A: Monitor electrolyte levels and administer potassium as needed. Patients on diuretic therapy are at risk of electrolyte imbalances, particularly low potassium levels. Monitoring electrolytes and administering potassium as needed are crucial nursing interventions to prevent imbalances. Choice B is incorrect because restricting fluid intake and providing a low-sodium diet are not typically indicated for patients on diuretic therapy. Choice C is incorrect as encouraging oral fluids and increasing dietary potassium can exacerbate electrolyte imbalances in patients on diuretics. Choice D is incorrect as providing high-sodium foods would worsen electrolyte balance issues in patients on diuretic therapy.
