Correct Answer: C

Rationale: Pinching the skin before inserting the needle is essential in elevating the subcutaneous tissue away from the muscle. This technique ensures that the medication is administered into the correct tissue layer, promoting proper absorption and decreasing the risk of injecting into muscle tissue.

Correct Answer: C

Rationale: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.

Correct Answer: B

Rationale: The correct answer is to put bed rails up on the side of the bed opposite from the nurse. This action is essential to prevent the client from falling out of bed during the turning process. Since the nurse can only stand on one side of the bed, having the bed rails up on the opposite side provides an additional safety measure. Securing the client's arm and leg or lowering the head of the bed would not prevent the client from falling and may pose a risk of injury. Using a turn sheet correctly can be helpful, but ensuring the bed rails are up is a more direct safety measure in this situation.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid foods high in iodine.' Clients with hyperthyroidism should avoid foods high in iodine to prevent exacerbation of their condition. Iodine is an essential component in thyroid hormone production, and excessive iodine intake can worsen hyperthyroidism symptoms. Taking medication with meals (B) can interfere with the absorption of certain thyroid medications. Monitoring weight daily (C) is more relevant for conditions that may lead to weight changes like hypothyroidism. Decreasing fluid intake (D) is not a standard recommendation for hyperthyroidism unless specifically indicated by the healthcare provider.

Correct Answer: C

Rationale: To ensure accurate creatinine clearance results, it is crucial to collect all urine within the 24-hour period. The process should begin with discarding the first specimen and then collecting all subsequent urine in the designated 24-hour collection container. This ensures that the sample is complete and accurate for the creatinine clearance calculation.
