HESI Fundamentals Practice Exam

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: B

Rationale: When a private room is not an option, the best choice is to assign the elderly client with influenza to a double room with another client diagnosed with the same condition. This is ideal as droplet precautions would likely already be in place for the other client, reducing the risk of spreading the infection to other clients in the unit. Choice A is not appropriate as impetigo does not require the same precautions as influenza. Choice C is not ideal as orthopedic surgery does not involve respiratory precautions. Choice D is incorrect because chickenpox requires airborne precautions, which could pose a risk to the elderly client with influenza.

Correct Answer: B

Rationale: The correct answer is B. The administration of opioid analgesics can impair balance and increase the risk of falls, justifying the inclusion of 'Risk for falls' in the client's care plan. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk of falls. Choice C, stooped posture with an unsteady gait, may indicate a risk for falls, but the direct influence of opioid analgesics on balance is more immediate. Choice D, expressed feelings of depression, while important, is not a direct indicator of the immediate risk for falls associated with opioid analgesic use.

Correct Answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

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.
