Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

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

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. A client is receiving IV antibiotic therapy for sepsis. Which assessment finding indicates that the client's condition is improving?

• A. Urine output increases to 25 mL/hour
• B. Client reports feeling less fatigued
• C. Heart rate decreases from 120 to 110 beats per minute
• D. White blood cell count decreases from 15,000 to 9,000/mm3

Correct answer: D

Rationale: The correct answer is D. A decrease in white blood cell count indicates that the infection is responding to treatment, making this the most objective indicator of improvement in a client with sepsis. Choices A, B, and C are subjective indicators and may not always directly correlate with the resolution of the underlying infection. While an increase in urine output, a client reporting feeling less fatigued, and a decrease in heart rate are positive signs, they are not as specific or directly related to the resolution of the infection as a decrease in white blood cell count.

3. A client is admitted with a suspected gastrointestinal bleed. What assessment finding requires immediate intervention?

• A. Bright red blood in the vomit.
• B. Elevated blood pressure and heart rate.
• C. Coffee ground emesis.
• D. Dark, tarry stools.

Correct answer: D

Rationale: Dark, tarry stools indicate the presence of digested blood in the gastrointestinal tract, signifying a higher gastrointestinal bleed. This finding requires immediate intervention due to the potential severity of the bleed. Bright red blood in the vomit may indicate active bleeding but is not as concerning as digested blood. Elevated blood pressure and heart rate are common responses to bleeding but do not provide direct evidence of the source or severity of the bleed. Coffee ground emesis is indicative of partially digested blood and is a concern but not as urgent as dark, tarry stools.

4. A client with hypertension is prescribed a beta-blocker. What teaching should the nurse provide about this medication?

• A. Instruct the client to avoid high-potassium foods.
• B. Monitor the client’s heart rate and report any bradycardia.
• C. Advise the client to rise slowly from a sitting or lying position.
• D. Instruct the client to avoid sudden position changes.

Correct answer: C

Rationale: The correct answer is to advise the client to rise slowly from a sitting or lying position. Beta-blockers can cause bradycardia and hypotension, so clients should be advised to rise slowly to prevent dizziness and falls. Monitoring the client's heart rate and blood pressure regularly is essential. Instructing the client to avoid high-potassium foods (Choice A) is not directly related to beta-blockers. While monitoring the client's heart rate (Choice B) is important, advising the client to rise slowly (Choice C) is more directly related to potential side effects of beta-blockers. Instructing the client to avoid sudden position changes (Choice D) is not as specific or essential as advising them to rise slowly to prevent adverse effects.

5. A client with cirrhosis is prescribed spironolactone to manage ascites. Which serum laboratory value is most important for the nurse to monitor?

• A. Sodium
• B. Calcium
• C. Magnesium
• D. Potassium

Correct answer: D

Rationale: The correct answer is D: Potassium. Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices A, B, and C are incorrect because sodium, calcium, and magnesium levels are not directly affected by spironolactone use for managing ascites in cirrhosis.
