Nursing Elites

1. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

2. A client with a history of diabetes mellitus is admitted with a foot ulcer. The nurse should recognize that which intervention is most critical in promoting healing of the foot ulcer?

• A. Strict control of blood glucose levels.
• B. Regular dressing changes with sterile technique.
• C. Application of antibiotic ointment.
• D. Hydrotherapy treatment daily.

Correct answer: A

Rationale: In diabetic clients with foot ulcers, strict control of blood glucose levels is essential for promoting wound healing. High blood glucose levels can impair circulation and compromise the body's ability to fight infection, delaying the healing process. By maintaining optimal blood glucose levels, the client's overall health and wound healing potential are improved.

3. A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?

• A. With meals
• B. At bedtime
• C. Before meals
• D. After meals

Correct answer: C

Rationale: Omeprazole is best taken before meals for optimal effectiveness in reducing stomach acid production and promoting ulcer healing. Taking it before meals allows the medication to act on the proton pumps before food intake triggers acid production, thereby maximizing its therapeutic benefits. Choices A, B, and D are incorrect because taking omeprazole with meals, at bedtime, or after meals may not align with its mechanism of action, potentially reducing its effectiveness in managing peptic ulcer disease.

4. 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.

5. A client with a history of chronic obstructive pulmonary disease (COPD) presents with increasing shortness of breath. Which assessment finding is most important for the nurse to report to the healthcare provider?

• A. Barrel-shaped chest.
• B. Use of accessory muscles to breathe.
• C. Oxygen saturation of 88%.
• D. Respiratory rate of 22 breaths per minute.

Correct answer: C

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical finding in a client with COPD. Hypoxemia can lead to serious complications and may require immediate intervention, such as adjusting oxygen therapy to improve oxygenation levels and prevent further respiratory distress. Monitoring and maintaining adequate oxygen saturation is crucial in managing COPD exacerbations and preventing respiratory failure.
