Correct Answer: C

Rationale: The correct answer is C: Dry mucous membranes. Dry mucous membranes are a common sign of dehydration as the body lacks adequate fluid. When a person is dehydrated, there is a decrease in saliva production, leading to dryness in the mouth and throat. This can be easily observed during a physical examination by looking at the patient's lips, tongue, and inside of the mouth. On the other hand, increased urine output (choice A) is a sign of adequate hydration, decreased heart rate (choice B) can be a normal response to dehydration but is not a consistent indicator, and increased blood pressure (choice D) is not typically associated with dehydration. Therefore, dry mucous membranes are the most reliable finding to suggest dehydration in a patient.

Correct Answer: A

Rationale: The correct answer is A: Severe headaches and blurred vision. These symptoms can indicate a hypertensive crisis, a severe complication of hypertension. Headaches and blurred vision are signs of potentially dangerous high blood pressure levels. Weight loss and fatigue (B), increased appetite and tremors (C), and nausea and vomiting (D) are not typical complications of hypertension and do not directly relate to the cardiovascular effects of high blood pressure. Monitoring for severe headaches and blurred vision is crucial for early detection and management of hypertensive crises.

Correct Answer: B

Rationale: The correct answer is B: Decrease intake of saturated fats. Saturated fats can raise cholesterol levels, leading to increased risk of heart disease and hypertension. Decreasing intake of saturated fats can help lower blood pressure. Incorrect choices: A: Increasing intake of foods high in sodium can worsen hypertension by increasing blood pressure. C: Increasing intake of processed foods often leads to higher sodium and saturated fat intake, worsening hypertension. D: Decreasing intake of fiber is not ideal as fiber helps in maintaining a healthy weight and managing blood pressure.
