Correct Answer: C

Rationale: The correct answer is C: Auscultate lung sounds. By auscultating lung sounds, the nurse can assess for changes in breath sounds which can indicate improvement or deterioration in the patient's condition. This helps monitor the effectiveness of therapy for a pneumothorax and chest-drainage system. Palpating for crepitus (A) is not directly related to monitoring therapy effectiveness. Documenting sputum color and amount (B) is important but does not specifically monitor therapy effectiveness. Monitoring suction level (D) is crucial but does not directly assess the patient's response to therapy.

Correct Answer: B

Rationale: The correct answer is B, Widening pulse pressure. This indicates increasing intracranial pressure (ICP) as it signifies a significant difference between systolic and diastolic blood pressure. A widening pulse pressure is a key sign of impending herniation and requires immediate intervention. A: Gradual increase does not provide a clear indication of acute changes in ICP. C: Rapid drop followed by gradual increase may suggest other conditions and is not specific to increasing ICP. D: Rapid fluctuations may occur in various scenarios and do not specifically point to increasing ICP. In summary, a widening pulse pressure is the most critical and specific indicator of increasing ICP among the choices provided.

Correct Answer: A

Rationale: The correct answer is A: Shrimp and tomatoes. Shrimp is a good source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Tomatoes are rich in Vitamin C, which helps enhance iron absorption. Cheese, bananas, lobster, squash, lamb, and peaches do not provide significant amounts of iron essential for an anemic client. The combination of shrimp and tomatoes offers a balanced approach to increase iron levels effectively.

Correct Answer: C

Rationale: The correct answer is C because priming the tubing of the blood administration set with 0.9% NS solution ensures that there are no air bubbles in the tubing, preventing air embolism when the blood transfusion starts. This step also ensures that the blood flows smoothly and prevents clotting in the tubing. Choice A is incorrect because adding IV medication in the blood bag can lead to incompatibility issues and should not be done without proper verification and approval. Choice B is incorrect because leaving the blood bag at room temperature for an hour can lead to bacterial growth in the blood, increasing the risk of infection when transfused. Choice D is unrelated to setting up supplies for a blood transfusion and does not address the immediate nursing intervention required in this situation.

Correct Answer: D

Rationale: The correct answer is D because a class V Pap test finding indicates severe abnormalities, such as high-grade dysplasia or carcinoma in situ. Therefore, the nurse should instruct the client to undergo a biopsy as soon as possible to confirm the diagnosis and initiate appropriate treatment promptly. Choices A, B, and C are incorrect because a class V result is not normal and requires immediate follow-up, rather than waiting or repeating the Pap test at a later time.
