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. While assessing a 70-year-old female client with Alzheimer's disease, the nurse notes deep inflamed cracks at the corners of her mouth. What intervention should the nurse include in this client's plan of care?

• A. Apply a moisturizing cream to the affected areas.
• B. Encourage the client to consume foods rich in vitamin B.
• C. Notify the healthcare provider for further evaluation.
• D. Ensure that the client gets adequate B vitamins in foods or supplements.

Correct answer: D

Rationale: Cracks at the corners of the mouth, known as angular cheilitis, can be a sign of vitamin B deficiency, specifically B2 (riboflavin) or B3 (niacin). The nurse should ensure that the client receives adequate B vitamins through foods rich in these nutrients or supplements to address the deficiency, which can help improve the condition of the client's mouth.

3. Which intervention should the nurse implement to enhance the efficacy of the client's asthma medication therapy?

• A. Administer the albuterol inhaler before other inhaled medications.
• B. Provide oxygen via nasal cannula at 2 liters/minute.
• C. Encourage the client to drink three liters of fluids daily.
• D. Keep the client upright during nebulizer therapy.

Correct answer: A

Rationale: Administering a bronchodilator such as albuterol as the first step is crucial to open the airways, allowing better penetration of subsequent inhaled medications and enhancing their overall efficacy in managing asthma symptoms.

4. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

5. The healthcare provider is planning care for a non-potty-trained child with nephrotic syndrome. Which intervention provides the best means of determining fluid retention?

• A. Weigh the child daily.
• B. Observe the lower extremities for pitting edema.
• C. Measure the child's abdominal girth weekly.
• D. Weigh the child's wet diapers.

Correct answer: A

Rationale: Daily weighing is the most accurate method to monitor fluid retention in a child with nephrotic syndrome. Changes in weight can indicate fluid retention or loss, which is crucial in managing nephrotic syndrome. Observing for pitting edema and measuring abdominal girth are also important assessments, but daily weighing provides more immediate and precise information about fluid status.
