HESI Fundamentals Practice Test

Correct Answer: B

Rationale: Engaging in moderate exercise for 30 minutes daily is a crucial lifestyle modification for managing hypertension. Regular physical activity helps lower blood pressure, improve cardiovascular health, and overall well-being. It is recommended to engage in activities like brisk walking, cycling, or swimming to achieve these benefits. Choices A, C, and D are incorrect. Limiting sodium intake, avoiding a diet high in saturated fats, and reducing alcohol consumption are also important lifestyle modifications for hypertension management, but engaging in moderate exercise is the most appropriate initial instruction for this client.

Correct Answer: A

Rationale: Performing range-of-motion exercises is essential in preventing contractures, which are common complications of immobility. These exercises help maintain joint flexibility and muscle strength, reducing the risk of contractures that can lead to functional limitations or pain for the client. Choices B, C, and D are incorrect. Decreasing fluid intake does not prevent immobility complications, but it can lead to dehydration. Massaging the client's legs does not directly address the prevention of immobility complications like contractures. Turning the client from side to back every shift is important for preventing pressure ulcers but does not directly address complications of immobility like contractures.

Correct Answer: B

Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.

Correct Answer: B

Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse is the site for auscultation when the blood pressure cuff is applied around the thigh. Auscultating the popliteal pulse with the cuff on the lower leg is incorrect as it may lead to an inaccurate reading. Placing the client in a prone position and wrapping the cuff around the girth of the leg are acceptable practices. A systolic reading that is 20 mm Hg higher in the lower extremity compared to the arm is expected due to the difference in blood pressure between the upper and lower parts of the body.
