Nursing Elites

1. 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.

2. When providing dietary instructions to a client with cirrhosis, which dietary restriction is important for the nurse to emphasize?

• A. Low-protein diet
• B. Low-sodium diet
• C. High-fiber diet
• D. High-calcium diet

Correct answer: B

Rationale: A low-sodium diet is crucial for clients with cirrhosis to manage fluid retention and ascites. Excessive sodium intake can worsen fluid accumulation in the body, leading to complications. By restricting sodium intake, the client can help reduce fluid retention and maintain better overall health. Therefore, emphasizing a low-sodium diet is essential in the dietary management of cirrhosis. Choices A, C, and D are not the primary focus for cirrhosis management. While protein restriction may be necessary in advanced stages of liver disease, it is not the main dietary concern in cirrhosis. High-fiber and high-calcium diets are generally beneficial for overall health but are not specifically emphasized in cirrhosis management.

3. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

4. The healthcare provider is assessing a client with Raynaud's phenomenon. Which finding should the healthcare provider expect?

• A. Thickened and hardened skin.
• B. Painless ulcers on the fingertips.
• C. Episodes of cyanosis and pallor in the fingers.
• D. Red, scaly patches on the hands.

Correct answer: C

Rationale: Raynaud's phenomenon is characterized by vasospasm, leading to episodes of cyanosis (bluish discoloration) and pallor (pale color) in the fingers or toes, often triggered by cold temperatures or stress. This occurs due to the reduced blood flow during vasospastic episodes, causing the discoloration. Choices A, B, and D are incorrect findings associated with other conditions and are not typical of Raynaud's phenomenon.

5. A client is scheduled for a colonoscopy. Which instruction should the nurse provide?

• A. Eat a light breakfast on the day of the procedure.
• B. You will need to drink a bowel preparation solution before the procedure.
• C. Avoid all liquids for 24 hours before the procedure.
• D. You can continue taking your blood thinners until the day of the procedure.

Correct answer: B

Rationale: The correct instruction for a client scheduled for a colonoscopy is to drink a bowel preparation solution before the procedure. This solution helps cleanse the colon, ensuring clear visualization during the colonoscopy procedure. Choice A is incorrect because a light breakfast is usually recommended the day before the procedure, not on the day of the colonoscopy. Choice C is incorrect as it is important to stay hydrated and follow specific instructions regarding liquid intake. Choice D is incorrect as blood thinners may need to be adjusted or stopped before the colonoscopy to reduce the risk of bleeding during the procedure.
