What are the key signs of hyperkalemia and how should it be treated?

Correct Answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

Correct Answer: A

Rationale: The correct intervention for a patient with hypokalemia is to administer potassium supplements and monitor the ECG. Potassium supplements help correct the low potassium levels in the body, while ECG monitoring is essential to detect any cardiac arrhythmias associated with hypokalemia. Choice B is incorrect because a high-sodium diet would worsen hypokalemia by further depleting potassium levels. Choice C is incorrect as it only focuses on monitoring symptoms and providing dietary education, but does not address the immediate need to correct potassium levels. Choice D is also incorrect as administering diuretics would exacerbate hypokalemia by increasing potassium loss.

Correct Answer: A

Rationale: Correct answer: The most appropriate management for a patient with congestive heart failure is to administer diuretics to help remove excess fluid and monitor fluid balance. Diuretics help reduce the workload on the heart and alleviate symptoms of fluid overload. Choice B is incorrect because patients with congestive heart failure are usually advised to limit sodium intake and carefully monitor fluid intake. Choice C is incorrect because although oxygen therapy may be necessary in certain cases, it is not the primary management for congestive heart failure. Pain relief is not a primary intervention for this condition. Choice D is incorrect because bronchodilators are not the first-line treatment for congestive heart failure. Encouraging mobility is important, but administering diuretics and monitoring fluid balance take precedence in managing this condition.

Correct Answer: A

Rationale: The correct answer is A: High sodium diet and lack of physical activity. These are established risk factors for developing hypertension as they contribute to elevated blood pressure. Choice B, low potassium intake and excessive alcohol consumption, may also impact blood pressure but are not as strongly associated with hypertension as high sodium intake and lack of physical activity. Choice C, frequent exercise and a low cholesterol diet, are actually beneficial for reducing the risk of hypertension. Choice D, smoking and family history, are more closely linked to other health conditions such as cardiovascular diseases, rather than being primary risk factors for hypertension.

Correct Answer: A

Rationale: The correct answer is A: A history of gastroesophageal reflux disease. Clients with gastroesophageal reflux disease have a higher risk of aspiration during tube feeding due to the potential for reflux of stomach contents into the lungs. This increases the risk of aspiration pneumonia. Choices B, C, and D are incorrect. High osmolarity formulas may cause diarrhea but do not directly increase the risk of aspiration. Sitting in a high-Fowler's position actually reduces the risk of aspiration by promoting proper digestion and reducing the chance of regurgitation. A residual of 65 mL 1 hour postprandial is within an acceptable range and does not directly indicate a risk for aspiration.
