What are the signs and symptoms of hyperkalemia and how should it be managed?

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: 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.

Correct Answer: A

Rationale: For a patient with diarrhea, the priority is to manage dehydration by providing oral fluids and monitoring stool consistency. Option B suggesting administering antidiarrheal medications is not recommended as it may prolong the infection by preventing the body from expelling the infectious agent. Option C is incorrect because antibiotics are not routinely indicated for diarrhea unless there is a specific bacterial infection. Option D is not the most appropriate initial intervention for managing diarrhea since a low-fiber diet may not provide adequate nutrition for the patient or help resolve the underlying cause of diarrhea.

Correct Answer: A

Rationale: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.

Correct Answer: A

Rationale: Type 1 diabetes is managed with insulin administration and regular blood glucose monitoring. Choice A is correct because administering insulin is essential in Type 1 diabetes management to help regulate blood glucose levels. Choices B, C, and D are incorrect because Type 1 diabetes requires insulin therapy as the primary treatment, not oral hypoglycemics or dietary modifications like low-carbohydrate or high-protein diets. Monitoring blood glucose levels is crucial in adjusting insulin doses and ensuring optimal management of the condition.
