Correct Answer: A

Rationale: When a client in a seclusion room following violent behavior continues to display aggression, it is essential for the nurse to confront the client about this behavior. Confrontation can help set boundaries, address the behavior, and ensure the safety of both the client and the healthcare team. Expressing sympathy (Choice B) may not address the immediate need for behavior management. Speaking assertively (Choice C) can be important but should be coupled with addressing the specific behavior. Standing within close proximity (Choice D) of an aggressive client can escalate the situation and compromise safety, so it is not the appropriate action to take.

Correct Answer: A

Rationale: Generalized petechiae and ecchymoses can indicate a potential issue with platelet function or count. Therefore, the most relevant laboratory test to evaluate this condition would be a platelet count. Platelet count helps assess the number of platelets in the blood, which are crucial for clotting and preventing bleeding. Monitoring platelet levels can provide important information about a client's bleeding risk and overall hematologic health.

Correct Answer: B

Rationale: Dyspnea is a key finding indicating fluid overload in a client receiving packed RBCs. Fluid overload can lead to pulmonary edema, causing difficulty breathing or shortness of breath (dyspnea). Low back pain is not typically associated with fluid overload but can be more related to musculoskeletal issues. Hypotension and thready pulse are more indicative of hypovolemia (low fluid volume), not fluid overload.

Correct Answer: A

Rationale: It is essential for the nurse to store the client's glasses in a labeled case to ensure they are kept safe and protected from damage. Storing them in a case helps prevent scratches, breakage, or misplacement. This practice promotes proper eyewear hygiene and ensures the client has their glasses readily available when needed. Cleaning the glasses with hot water or a paper towel can potentially damage the lenses or frames. Storing the glasses on the bedside table increases the risk of misplacement or damage.

Correct Answer: B

Rationale: During a gastric lavage procedure for upper gastrointestinal bleeding, inserting a large-bore NG tube is essential to effectively remove gastric contents and blood. This tube allows for efficient irrigation and suction, aiding in the removal of harmful substances from the stomach. Instilling a large volume of solution or using a cold irrigation solution can lead to complications such as fluid overload or hypothermia. Instructing the client to lie on their right side is not directly related to the gastric lavage procedure.
