HESI Fundamentals Practice Exam

Correct Answer: A

Rationale: To calculate the total daily dose of furosemide needed, 40 mg BID (twice a day) is 80 mg/day. Since each tablet is 20 mg, the client should receive a total of 4 tablets per day (80 mg � 20 mg per tablet = 4 tablets). Therefore, the correct answer is 4 tablets. Choice B (3 tablets) is incorrect because it does not provide the correct total daily dose. Choice C (2 tablets) is incorrect as it would not meet the required dose of 80 mg/day. Choice D (1 tablet) is incorrect as it would be insufficient to achieve the prescribed daily dose.

Correct Answer: B

Rationale: Hinge joints, like the elbow, primarily allow movement in one direction, in this case, bending the arm. The correct action to exercise hinge joints is to bend the arm by flexing the ulnar to the humerus. This movement specifically targets the hinge joint and promotes its range of motion. Choices A, C, and D involve movements that do not specifically target hinge joints. Tilt the pelvis involves the ball-and-socket joints of the hip, turning the head involves the pivot joint of the neck, and extending the arm and rotating it in circles involve multiple joints including ball-and-socket and pivot joints.

Correct Answer: D

Rationale: When a client begins to cough and gag during the insertion of a nasogastric tube, withdrawing the tube slightly and pausing is the appropriate action. This technique helps prevent further irritation, gives the client a moment to recover, and allows for a smoother continuation of the insertion process. Choice A is incorrect because allowing the client to rest without adjusting the tube position might not address the issue. Choice B is incorrect as removing the tube without addressing the cause of coughing and gagging may lead to repeated discomfort. Choice C is incorrect as continuing to insert the tube while the client is experiencing difficulties can increase discomfort and potential complications.

Correct Answer: D

Rationale: Restricting dietary sodium intake (D) is the most critical intervention for a client with fluid volume excess to prevent further fluid retention. Encouraging increased fluid intake (A) would exacerbate the issue by adding more fluid to the body. Placing the client in a high Fowler's position (B) is more relevant for respiratory issues than fluid volume excess. While measuring intake and output (C) is important for assessing fluid balance, restricting sodium intake is the priority as it helps manage fluid levels more effectively by reducing fluid retention.

Correct Answer: D

Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.
