Correct Answer: A

Rationale: The correct next step for the nurse is to assess the client for confusion and reteach the procedure. This is crucial to ensure that the older adult male understands the process correctly, reducing the likelihood of errors in collecting the 24-hour urine specimen for creatinine clearance. Checking the urine for color and texture (Choice B) is not the immediate next step as the focus should be on patient understanding first. Emptying the urinal contents into the 24-hour collection container (Choice C) assumes prior knowledge on the client's part and skips the critical step of ensuring comprehension. Discarding the contents of the urinal (Choice D) is incorrect and wasteful since the urine is necessary for the 24-hour collection process.

Correct Answer: B

Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.

Correct Answer: B

Rationale: Repositioning the client every 2 hours is the most appropriate action to prevent further skin breakdown in a client with a pressure ulcer on the sacrum. This practice helps relieve pressure on the affected area, promoting circulation and reducing the risk of tissue damage. Applying a hydrocolloid dressing (Choice A) may be beneficial for wound healing but is not the initial preventive measure. Using a donut-shaped cushion (Choice C) can actually increase pressure on the sacrum and worsen the condition. Massaging the area around the ulcer (Choice D) can further damage delicate skin and tissues, leading to more harm instead of prevention.

Correct Answer: D

Rationale: When admitting a client to a medical-surgical unit, documenting the admission date and time is crucial as it establishes the timeline for the client's care. This information ensures accurate tracking of interventions and facilitates communication among the healthcare team. While assessment, history of present illness, and plan of care are important components of the admission process, documenting the admission date and time takes priority to establish a baseline for care delivery. Without the admission date and time, the continuity of care and coordination among healthcare providers may be compromised.

Correct Answer: D

Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a potential side effect of long-term antipsychotic use, characterized by involuntary movements like lip smacking and repetitive, purposeless movements. Choice A, dystonia, presents with sustained or repetitive muscle contractions. Choice B, akathisia, involves motor restlessness and a compelling need to be in constant motion. Choice C, bradykinesia, refers to slowness of movement typically seen in Parkinson's disease, not lip smacking and teeth grinding, which are indicative of tardive dyskinesia.
