Nursing Elites

1. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?

• A. Wilson's disease
• B. Hemochromatosis
• C. Alpha-1 antitrypsin deficiency
• D. Autoimmune hepatitis

Correct answer: B

Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.

2. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.

3. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?

• A. To lower blood sugar levels
• B. To reduce ammonia levels
• C. To treat liver inflammation
• D. To improve bile flow

Correct answer: B

Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.

4. A patient with bipolar disorder is prescribed lithium. What dietary advice should the nurse provide?

• A. Increase intake of caffeine.
• B. Maintain a consistent salt intake.
• C. Avoid dairy products.
• D. Increase intake of green leafy vegetables.

Correct answer: B

Rationale: The correct answer is B: Maintain a consistent salt intake. Patients prescribed lithium should maintain a consistent salt intake to help stabilize lithium levels. Fluctuations in salt intake can affect the levels of lithium in the body, potentially leading to toxicity or reduced effectiveness of the medication. It is important for patients to be consistent with their salt intake and to avoid sudden increases or decreases. Choices A, C, and D are incorrect. Increasing intake of caffeine is not recommended as it can interfere with the effects of lithium. Avoiding dairy products is not necessary unless there are specific intolerances or interactions with other medications. While green leafy vegetables are generally healthy, there is no specific recommendation to increase their intake in relation to lithium therapy.

5. A patient who is receiving chemotherapy for breast cancer develops thrombocytopenia. What should the nurse include in the care plan?

• A. Encourage light exercise.
• B. Avoid intramuscular injections.
• C. Do not administer aspirin.
• D. Use a soft toothbrush for oral care.

Correct answer: B

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. To minimize this risk, patients with thrombocytopenia should avoid activities that can cause injury or bleeding, such as intramuscular injections. Encouraging light exercise can be beneficial, as it promotes circulation without increasing the risk of trauma. However, avoiding intramuscular injections is crucial to prevent bleeding episodes. Aspirin should be avoided as it can further impair platelet function, exacerbating the condition. Using a soft toothbrush for oral care is recommended to prevent gum bleeding in patients with thrombocytopenia.
