Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is providing discharge teaching to a client following a cholecystectomy. Which of the following instructions should the nurse include?

• A. I should avoid lifting objects heavier than 5 pounds for 1 week.
• B. I can resume my usual activities after 2 weeks.
• C. I should expect to have pain in my right shoulder.
• D. I should follow a low-protein diet for 1 week.

Correct answer: C

Rationale: The correct answer is C. Pain in the right shoulder after a cholecystectomy is common due to residual gas from the procedure. Choices A, B, and D are incorrect. It is important to avoid heavy lifting for a longer period than just 1 week to prevent complications. Resuming usual activities after 2 weeks may not be appropriate depending on the individual's recovery. Following a low-protein diet is not a standard recommendation post-cholecystectomy.

3. A nurse is providing teaching about folic acid to a client who is primigravida. Which of the following information should the nurse include in the teaching?

• A. You should take folic acid to prevent neural tube defects in your baby.
• B. You should consume at least 400 micrograms of folic acid daily.
• C. You can increase your dietary intake of folic acid by consuming cereals and citrus fruits.
• D. You should expect improved energy levels when taking folic acid supplements.

Correct answer: C

Rationale: The correct answer is C. Folic acid helps prevent neural tube defects, and dietary sources like cereals and citrus fruits are good options to increase folic acid intake. Choice A is incorrect because folic acid is primarily recommended to prevent neural tube defects, not to prevent infections. Choice B is incorrect because the recommended daily intake of folic acid for pregnant women is at least 400 micrograms, not 300. Choice D is incorrect because folic acid is not typically associated with improving energy levels.

4. A nurse is caring for a client who has septic shock. Which of the following findings should the nurse report to the provider?

• A. Temperature of 38°C (100.4°F).
• B. Urinary output of 40 mL/hr.
• C. Heart rate of 92/min.
• D. Capillary refill time of 2 seconds.

Correct answer: B

Rationale: The correct answer is B. A urinary output of 40 mL/hr is below the expected range and should be reported to the provider as it may indicate impaired kidney function, which is crucial to monitor in a client with septic shock. Choices A, C, and D are within acceptable ranges for a client with septic shock and do not indicate immediate concerns. A temperature of 38°C (100.4°F) is slightly elevated but can be expected in septic shock. A heart rate of 92/min is within the normal range for an adult. A capillary refill time of 2 seconds is also normal, indicating adequate peripheral perfusion.

5. A nurse is planning care for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the therapy?

• A. Serum calcium level
• B. Platelet count
• C. INR
• D. WBC count

Correct answer: C

Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.
