1. While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. INR
- C. aPTT
- D. Platelet count
Correct answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation. Choices A, B, and D are incorrect. PT (Prothrombin Time) and INR (International Normalized Ratio) are used to monitor Warfarin therapy, not Heparin. Platelet count is important in assessing for thrombocytopenia but is not a specific indicator of Heparin therapy effectiveness.
2. 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.
3. A client has a new prescription for Nevirapine, an NNRTI. Which of the following statements should the nurse include in teaching the client?
- A. Take this medication on an empty stomach.
- B. Take this medication with food to increase absorption.
- C. Avoid alcohol while taking this medication.
- D. Take this medication at the same time every day.
Correct answer: B
Rationale: The correct statement that the nurse should include in teaching the client about Nevirapine, an NNRTI, is to take the medication with food to improve gastrointestinal tolerance and prevent nausea. While absorption is not significantly affected by food, taking it with meals can help reduce adverse gastrointestinal effects. Choice A is incorrect because Nevirapine should not be taken on an empty stomach. Choice C is generally true for most medications but is not specific to Nevirapine. Choice D is a good practice for medication adherence but is not specific to the administration requirements of Nevirapine.
4. A client is receiving discharge instructions for long-term use of Prednisone. Which of the following instructions should be included?
- A. Stop taking the medication if you experience swelling.
- B. The provider will monitor your weight regularly.
- C. Take the medication on an empty stomach.
- D. You may notice decreased appetite while on this medication.
Correct answer: B
Rationale: The correct answer is B because long-term use of Prednisone can lead to weight gain, necessitating regular weight monitoring by the healthcare provider to manage any potential complications. Prednisone often causes fluid retention, leading to weight gain, hence the need for weight monitoring. Options A, C, and D are incorrect because swelling is not a typical reason to stop Prednisone, taking it on an empty stomach is not usually required, and Prednisone commonly increases appetite rather than decreases it.
5. While reviewing a client's medical history, a healthcare professional notes a prescription for Digoxin. Which of the following findings is a manifestation of Digoxin toxicity?
- A. Elevated blood pressure
- B. Bradycardia
- C. Yellow-tinged vision
- D. Ringing in the ears
Correct answer: C
Rationale: Yellow-tinged vision is a visual disturbance associated with Digoxin toxicity, often accompanied by other symptoms like nausea, vomiting, and confusion. Bradycardia is a common therapeutic effect of Digoxin, while elevated blood pressure and ringing in the ears are not typically associated with Digoxin toxicity. Therefore, the correct answer is yellow-tinged vision as a manifestation of Digoxin toxicity.
