1. A client receiving total parenteral nutrition (TPN) through a central line suddenly develops dyspnea, chest pain, and a drop in blood pressure. What should the nurse do first?

Correct answer: C

Rationale: Placing the client in Trendelenburg position should be the initial action as it can help manage a suspected air embolism, a potential complication of TPN administration. This position helps trap air in the apex of the atrium, reducing the risk of air reaching the pulmonary circulation and causing further harm. Once the client is in a safe position, further actions such as stopping the TPN infusion, notifying the healthcare provider, and administering oxygen can be taken as appropriate.

2. The nurse is caring for a client with a history of deep vein thrombosis (DVT) who is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

Correct answer: B

Rationale: Prothrombin time (PT) is monitored to ensure therapeutic levels of warfarin and prevent bleeding complications.

3. When assessing a client with a chest tube connected to suction, which observation indicates that the chest tube is functioning properly?

Correct answer: D

Rationale: Steady bubbling in the suction control chamber is the correct observation that indicates the chest tube is functioning properly. This steady bubbling signifies that the suction is actively maintaining the desired pressure level within the system, ensuring proper drainage and lung re-expansion. Continuous bubbling in the water seal chamber, intermittent bubbling in the suction control chamber, or no fluctuation in the water seal chamber are not indicative of optimal chest tube function and may require further assessment or intervention.

4. A 55-year-old man presents with jaundice, pruritus, and dark urine. Laboratory tests reveal elevated bilirubin and alkaline phosphatase. Imaging shows dilated intrahepatic bile ducts and a normal common bile duct. What is the most likely diagnosis?

Correct answer: A

Rationale: The clinical presentation of jaundice, pruritus, dark urine, elevated bilirubin and alkaline phosphatase, along with imaging findings of dilated intrahepatic bile ducts and a normal common bile duct, are characteristic of primary biliary cirrhosis. Primary biliary cirrhosis is an autoimmune liver disease that leads to destruction of intrahepatic bile ducts, causing cholestasis and liver damage. This condition typically presents in middle-aged women but can also affect men, as seen in this case.

5. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.
