Correct Answer: C

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increasing fiber intake can aid in managing hypertension by promoting heart health and overall well-being. Choices A, B, and D are incorrect. Increased sodium intake is not recommended for hypertension as it can elevate blood pressure. Decreasing potassium intake is also not advised as potassium is essential for regulating blood pressure. Lastly, increasing cholesterol intake is detrimental for hypertension as it can contribute to cardiovascular issues and worsen the condition.

Correct Answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys play a crucial role in regulating potassium levels in the body. In renal failure, the kidneys may not be able to excrete excess potassium effectively, leading to hyperkalemia. Calcium, iron, and zinc are not typically restricted in chronic renal failure unless there are specific individual circumstances, making them incorrect choices.

Correct Answer: D

Rationale: Correct! Anxiety and exercise can significantly alter the character of respirations, increasing the rate and depth. Smoking, while harmful to the respiratory system in the long term, does not directly affect the character of respirations like anxiety and exercise do. Therefore, choices C (Smoking) is incorrect. The correct answer is D (A, B).

Correct Answer: A

Rationale: Obesity is a primary factor that affects blood pressure. Excess body weight, especially when concentrated around the abdomen, can increase the risk of hypertension (high blood pressure) as it puts extra strain on the heart to pump blood around the body. This can lead to various cardiovascular complications and other health issues. Managing weight through a healthy diet and regular physical activity can help control blood pressure levels. Age, stress, and gender can also influence blood pressure, but obesity has a more direct and significant impact on increasing blood pressure levels compared to the other factors listed.

Correct Answer: C

Rationale: In the context of field medical training for mobilization, proficiency in common soldier tasks is essential. This includes skills like first aid, navigation, marksmanship, and other fundamental military tasks. While command and control procedures, communications, and automation are important, common soldier tasks are specifically mentioned in the scenario as critical for achieving readiness and mobilization.
