Question 1 of 5

Which lab value is critical for monitoring warfarin therapy?

Correct Answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

Question 2 of 5

Nurses caring for four clients. Which of the following client data should the nurse report to the provider?

Correct Answer: D

Rationale: The correct answer is D. The client with chemotherapy and a low neutrophil count is at risk for infection and requires prompt intervention. Reporting this information to the provider is crucial to ensure appropriate monitoring and management to prevent potential complications. Choices A, B, and C do not indicate an immediate risk that requires immediate provider notification. A client reporting pain with pleurisy, a client draining fluid post-surgery, or a client with a heart rate of 98 per minute postoperative are not urgent enough to warrant immediate reporting compared to the client at risk for infection.

Question 3 of 5

A nurse is completing a dietary assessment for a client who is Jewish and observes kosher dietary practices. Which of the following behaviors should the nurse expect to find?

Correct Answer: C

Rationale: The correct answer is C. Kosher dietary laws require the separation of meat and dairy products. Choice A is incorrect because leavened bread is not eaten during Passover in Jewish dietary practices. Choice B is incorrect as shellfish is not considered kosher and is not consumed in Jewish dietary practices. Choice D is incorrect as fasting from meat does not occur during Hanukkah.

Question 4 of 5

A nurse is planning care for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

Correct Answer: A

Rationale: In the context of chronic kidney disease (CKD), a glomerular filtration rate (GFR) of 14 mL/minute indicates severe kidney dysfunction. GFR measures how well the kidneys are filtering waste from the blood. When GFR drops below 15 mL/minute, it indicates end-stage renal disease (ESRD) where dialysis is required to remove waste and excess fluid from the body. This critical level of kidney function necessitates the initiation of hemodialysis to maintain the client's health and prevent complications of uremia. Option B, a blood urea nitrogen (BUN) level of 16 mg/dL, is within the normal range (7-20 mg/dL) and does not directly indicate the need for hemodialysis. Similarly, options C and D, serum magnesium and phosphorus levels within normal ranges, do not serve as indicators for the initiation of hemodialysis in CKD. Educationally, understanding the significance of GFR levels in CKD management is crucial for nurses caring for clients with kidney disease. Recognizing the appropriate indications for hemodialysis helps nurses intervene in a timely manner, ensuring optimal patient outcomes and quality of life. This rationale underscores the importance of clinical judgment based on laboratory values in the comprehensive care of clients with chronic conditions like CKD.

Question 5 of 5

While reviewing the monitor tracing of a client in labor, a nurse notes late decelerations. Which of the following interventions should the nurse perform?

Correct Answer: B

Rationale: Repositioning the client onto her left side is the appropriate intervention when late decelerations are noted on the monitor tracing. This action helps increase uteroplacental blood flow by relieving pressure on the vena cava and aorta, improving fetal oxygenation. Administering oxygen via nasal cannula may be indicated for variable decelerations, not late decelerations. Administering an amnioinfusion is not the primary intervention for late decelerations. Providing reassurance to the client is important but addressing the underlying cause of late decelerations takes precedence.
