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: 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: The correct answer is D. The nurse should first address the immediate comfort concern of the client, which is the weight of the linen on her legs causing severe joint pain. By draping the sheets over the footboard of the bed rather than tucking them under the mattress, the nurse can alleviate the pressure that the client perceives as the source of her pain. This action is a simple and effective way to provide relief and should be the initial step taken by the nurse. Choices A, B, and C do not directly address the client's immediate discomfort caused by the weight of the linen on her legs, making them less appropriate initial actions.

Correct Answer: D

Rationale: The nurse should carefully monitor serum sodium levels for a client with an NG tube on suction for an extended period due to potential fluid loss and the risk of developing hyponatremia, an electrolyte imbalance. Hyponatremia can occur as a result of continual suctioning leading to fluid loss, making it crucial to monitor sodium levels to prevent complications associated with low sodium levels. Monitoring white blood cell count, albumin, or calcium is not directly related to the impact of NG tube suction on fluid and electrolyte balance, so these values are not the priority in this scenario.

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.
