Correct Answer: B

Rationale: In this scenario, the immediate need is to provide passive immunity to the adolescent patient. Gamma globulin contains antibodies against hepatitis B, which can offer immediate protection. The hepatitis B vaccine provides active immunity over time but is not immediate. Fresh frozen plasma and corticosteroids are not indicated for immediate protection against hepatitis B infection.

Correct Answer: A

Rationale: The correct preparation for a paracentesis in a patient with cirrhosis and ascites includes having the patient void immediately before the procedure. This is important to reduce the risk of bladder puncture during the paracentesis. Positioning for a paracentesis is typically upright or semi-Fowler's, not flat in bed. Administering a full liquid diet or encouraging ambulation for 30 minutes are not directly related to preparing a patient for a paracentesis procedure.

Correct Answer: B

Rationale: The partial thromboplastin time (PTT) is the laboratory test that should be monitored to evaluate the effectiveness of heparin therapy in patients with deep vein thrombosis (DVT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding.

Correct Answer: D

Rationale: The nurse's priority action in this situation is to notify the healthcare provider immediately. These symptoms, including severe pain, swelling, warmth, and redness in the leg, are indicative of deep vein thrombosis (DVT), a potentially serious condition. Prompt notification of the healthcare provider is crucial to initiate appropriate diagnostic tests and interventions to prevent complications associated with DVT.

Correct Answer: C

Rationale: The primary reason for administering morphine to a patient with a myocardial infarction (MI) is to reduce cardiac workload. Morphine helps in reducing preload and afterload, which ultimately improves oxygenation to the heart muscle. By decreasing the workload on the heart, morphine can alleviate symptoms and decrease the strain on the heart muscle during an MI.
