Correct Answer: C

Rationale: The correct answer is C. Drinking caffeinated beverages can potentially increase blood pressure due to their stimulant effect. Limiting caffeine intake is recommended for patients with hypertension. Statement A is correct as reducing sodium and increasing potassium intake can help lower blood pressure. Statement B is correct as processed foods and fast food are typically high in sodium and unhealthy fats, which can worsen hypertension. Statement D is correct as fruits, vegetables, and whole grains are part of a heart-healthy diet for managing hypertension.

Correct Answer: C

Rationale: Step 1: Hypertension is often worsened by high sodium intake. Step 2: Decreasing sodium intake helps lower blood pressure. Step 3: This dietary change aligns with hypertension management. Step 4: Increasing processed foods (A), saturated fats (D), or potassium intake (B) do not directly address the issue of high sodium intake and may even exacerbate hypertension.

Correct Answer: B

Rationale: The correct assessment is B because providing consistent information indicates reliability. Drug abuse history (A) does not necessarily mean the patient is unreliable. Smiling (C) is not a reliable indicator. Refusal to answer specific questions (D) does not negate overall reliability.

Correct Answer: B

Rationale: The main role of the nursing process in community health care is to provide individualized care frameworks. This involves assessing, diagnosing, planning, implementing, and evaluating care tailored to each patient's unique needs. Nursing interventions are personalized based on the individual's health status, preferences, and community resources. This approach promotes holistic and patient-centered care, leading to better health outcomes. The other choices are incorrect because: A: Implementing standardized treatment plans does not account for individual variations and needs. C: Nurses collaborate with diagnostic physicians but do not solely assist them. D: Establishing clinical guidelines is important but not the primary role of the nursing process in community health care.

Correct Answer: A

Rationale: The correct answer is A: Apply a splint. This is the first step because immobilizing the affected limb helps prevent further injury and reduces pain. Administering fluids (B) and oxygen (C) are important but not the priority in this situation. Elevating the limb (D) can wait until the fracture is stabilized.
