Nursing Elites

1. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

• A. Gram stain
• B. Culture
• C. Sensitivity
• D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.

2. When caring for a client prescribed warfarin, which laboratory test should the nurse monitor to evaluate the therapeutic effect of the medication?

• A. aPTT
• B. Platelet count
• C. BUN
• D. PT/INR

Correct answer: D

Rationale: The correct laboratory test to monitor the therapeutic effect of warfarin is the PT/INR. Warfarin affects blood clotting, and the PT/INR levels indicate the effectiveness of the medication in preventing clot formation. Therefore, monitoring PT/INR levels helps ensure that the client is within the therapeutic range and is protected from potential complications related to clotting. Choice A (aPTT) is incorrect because while it measures the clotting time, it is not the preferred test for monitoring warfarin therapy. Choice B (Platelet count) is incorrect as it assesses the number of platelets and not the medication's therapeutic effect. Choice C (BUN) is unrelated to monitoring the effects of warfarin therapy and is primarily used to assess kidney function.

3. A client presents in the Emergency Department with a suspected MI. Which medication should NOT be given as soon as possible?

• A. Clopidogrel (Plavix)
• B. Morphine
• C. Aspirin (ASA)
• D. Metoprolol (Lopressor)

Correct answer: A

Rationale: In the setting of a suspected myocardial infarction (MI), the priority medications to administer as soon as possible include aspirin (ASA) and possibly morphine to manage pain and anxiety. Clopidogrel (Plavix) is not typically administered immediately in the emergency setting for MI management. Metoprolol (Lopressor) is indicated after aspirin administration and stabilization of the patient. Therefore, in this scenario, clopidogrel should NOT be given as a first-line medication for a suspected MI.

4. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?

• A. Apply the patch to a different site each day.
• B. Remove the patch at bedtime each day.
• C. Apply the patch over an area with little or no hair.
• D. Keep the patch on for 24 hours at a time.

Correct answer: B

Rationale: The correct instruction for a client using a Nitroglycerin transdermal patch is to remove the patch each day, usually at bedtime, to prevent tolerance. This practice allows for a nitrate-free interval, reducing the risk of developing tolerance to the medication. Applying the patch to a different site each day (choice A) is not necessary as long as the skin is clean and rotated to avoid skin irritation. Applying the patch over an area with little or no hair (choice C) does not impact the effectiveness of the medication. Keeping the patch on for 24 hours at a time (choice D) can lead to tolerance, which is why the patch should be removed daily.

5. A client in an outpatient facility is taking Acarbose for type 2 Diabetes Mellitus. Which of the following laboratory tests should the nurse plan to monitor?

• A. WBC
• B. Serum potassium
• C. Platelet count
• D. Liver function test

Correct answer: D

Rationale: The correct answer is D: Liver function test. Acarbose, used for type 2 Diabetes Mellitus, can lead to liver toxicity with long-term use. Monitoring liver function tests periodically is crucial to detect any signs of liver dysfunction early and prevent complications. Choices A, B, and C are incorrect as Acarbose does not directly affect WBC, serum potassium, or platelet count levels.
