HESI Fundamentals Practice Exam

Correct Answer: B

Rationale: Active ROM exercises are preferred over passive ROM to restore strength. Performing them on both arms and legs two or three times a day is effective in promoting muscle strength and mobility without the need for external assistance. Choice A is incorrect as passive ROM exercises may not help in restoring strength. Choice C is not recommended as using weights may be too strenuous for a weak client. Choice D is incorrect as passive ROM exercises to the point of resistance and slightly beyond may cause discomfort or injury to the weak client.

Correct Answer: D

Rationale: When a client becomes angry while waiting for a supervised break, it is essential to address their concerns effectively. Reviewing the schedule of outdoor breaks with the client provides concrete information, helps manage the client's expectations, and may alleviate their frustration. This intervention promotes transparency and empowers the client by clarifying the timing of their desired break, fostering a therapeutic and collaborative nurse-client relationship. Encouraging the client to use a nicotine patch (Choice A) does not address the client's immediate frustration with the break schedule. Reassuring the client about another break (Choice B) may temporarily placate them but does not address the underlying issue. Having the client leave the unit with another staff member (Choice C) may not be feasible or appropriate at that moment and does not address the client's concerns.

Correct Answer: B

Rationale: The statement 'I should avoid using my inhaler unless I am having an asthma attack' (B) indicates a need for further teaching. It is important for clients to use their inhaler as prescribed, which may include regular use to prevent asthma attacks. Choice A is correct because using the inhaler when feeling short of breath can help manage asthma symptoms. Choice C is also correct as using the inhaler before exercise can prevent exercise-induced symptoms. Choice D is correct as rinsing the mouth after using the inhaler helps prevent oral thrush, a potential side effect of inhaled corticosteroids. Therefore, option B is the most concerning statement that needs clarification.

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: 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.
