How should a healthcare professional respond to a patient with hypokalemia?

Correct Answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.

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: A

Rationale: In sepsis, it is crucial to monitor vital signs to assess the patient's condition and administer fluids to maintain circulation. This approach helps in stabilizing blood pressure and perfusion. While monitoring for fever and administering antibiotics (choice B) is important in managing sepsis, the initial priority lies in assessing and stabilizing the patient's hemodynamic status. Checking for tachycardia and elevated white blood cell count (choice C) can be part of the assessment but does not encompass the immediate intervention needed in sepsis. Administering fluids and providing nutritional support (choice D) are essential in managing sepsis, but the primary step should be to assess the patient's condition through vital sign monitoring.

Correct Answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

Correct Answer: A

Rationale: The correct answer is A: Obesity, sedentary lifestyle, and poor diet are established risk factors for developing Type 2 diabetes. Obesity puts extra pressure on the body's ability to properly control blood sugar levels. A sedentary lifestyle contributes to weight gain and insulin resistance. Poor diet, especially one high in processed foods and sugary beverages, can also increase the risk of developing Type 2 diabetes. Choices B, C, and D are incorrect because age, gender, family history, smoking, alcohol consumption, and hypertension can impact overall health but are not the primary risk factors for Type 2 diabetes.
