Nursing Elites

1. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.

2. A client with chronic renal failure is receiving peritoneal dialysis. The nurse notes that the client's dialysate output is less than the input and that the client's abdomen is distended. What action should the nurse take first?

• A. Turn the client from side to side
• B. Increase the dwell time of the dialysis
• C. Reposition the client
• D. Milk the catheter

Correct answer: A

Rationale: The correct first action for the nurse to take is turning the client from side to side. This helps to facilitate drainage in peritoneal dialysis. Turning the client can aid in redistributing the dialysate and promoting better drainage. Increasing the dwell time of the dialysis (choice B) may not address the immediate issue of inadequate drainage. Repositioning the client (choice C) might not be as effective as turning the client from side to side. Milking the catheter (choice D) is not recommended as it can lead to complications. In this situation, the priority is to facilitate drainage to address the distended abdomen.

3. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

4. A 14-year-old girl with asthma complains of feeling nervous and jittery after a respiratory therapy bronchodilator treatment. What explanation is best for the nurse to provide to this adolescent?

• A. Nervousness should disappear when hypoxia is relieved after several bronchodilator treatments
• B. Tremors result from the rapid dilation of the bronchioles and an increased heart rate
• C. A fast heart rate and jitteriness are side effects of the bronchodilator treatment containing albuterol
• D. Excessive coughing, which causes tachypnea and anxiety, result from the use of bronchodilators

Correct answer: C

Rationale: The correct answer is C because a fast heart rate and jitteriness are common side effects of bronchodilators like albuterol. Choice A is incorrect as nervousness is more likely a side effect of the medication than solely related to hypoxia. Choice B is incorrect as it provides a partial explanation focusing only on tremors and heart rate, not mentioning jitteriness. Choice D is incorrect because excessive coughing and tachypnea are not typically associated with bronchodilator use; instead, they may indicate inadequate relief or other issues.

5. A college student who is diagnosed with a vaginal infection and vulva irritation describes the vaginal discharge as having a 'cottage cheese' appearance. Which prescription should the nurse implement first?

• A. Cleanse the perineum with warm soapy water 3 times per day
• B. Instill the first dose of nystatin (Mycostatin) vaginally per applicator
• C. Perform a glucose measurement using a capillary blood sample
• D. Obtain a blood specimen for sexually transmitted diseases (STDs)

Correct answer: B

Rationale: The correct answer is to instill the first dose of nystatin vaginally per applicator. Nystatin is an antifungal medication used to treat yeast infections, which are characterized by 'cottage cheese' discharge. Cleansing the perineum with warm soapy water may help with hygiene but does not address the underlying infection. Performing a glucose measurement is not relevant to the diagnosis of a vaginal infection. Obtaining a blood specimen for STDs is not the priority in this scenario as the symptoms described are indicative of a yeast infection.
