Nursing Elites

1. A client with deep vein thrombosis receiving heparin therapy needs monitoring. Which test should the nurse use to regulate the medication dosage?

• A. Prothrombin time (PT)
• B. International Normalized Ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Fibrinogen levels

Correct answer: C

Rationale: The correct answer is C: Activated partial thromboplastin time (aPTT). aPTT is specifically used to monitor and regulate heparin therapy as it assesses the intrinsic pathway of coagulation, which heparin affects. Options A and B, Prothrombin time (PT) and International Normalized Ratio (INR), are used to monitor warfarin therapy, not heparin. Option D, Fibrinogen levels, is not the primary test used to monitor heparin therapy.

2. A healthcare provider is assessing a client who has heart failure and is taking digoxin. Which of the following findings should the healthcare provider identify as an indication of digoxin toxicity?

• A. Bradycardia.
• B. Yellow-tinged vision.
• C. Constipation.
• D. Hypertension.

Correct answer: B

Rationale: Yellow-tinged vision is a classic sign of digoxin toxicity due to its effect on the eyes. It can cause a yellow or green visual halo around objects. Bradycardia, constipation, and hypertension are not typical signs of digoxin toxicity. Bradycardia may be a sign of digoxin's therapeutic effect in heart failure, while constipation and hypertension are not commonly associated with digoxin toxicity.

3. A nurse is assessing a client who has pericarditis. Which of the following findings is the priority?

• A. Paradoxical pulse
• B. Dependent edema
• C. Pericardial friction rub
• D. Substernal chest pain

Correct answer: A

Rationale: In a client with pericarditis, the priority finding is a paradoxical pulse. This is a crucial sign of cardiac tamponade, a life-threatening complication of pericarditis where fluid accumulates in the pericardial sac, causing compression of the heart. A paradoxical pulse is an exaggerated decrease in systolic blood pressure (>10 mmHg) during inspiration. Prompt recognition and intervention are essential to prevent hemodynamic instability and cardiac arrest. Dependent edema (choice B) is not typically associated with pericarditis. Pericardial friction rub (choice C) is a common finding in pericarditis but does not indicate the urgency of intervention as a paradoxical pulse. Substernal chest pain (choice D) is a classic symptom of pericarditis but is not as critical as a paradoxical pulse in the context of assessing for complications.

4. A client with type 2 diabetes mellitus is scheduled for an arteriogram. Which of the following medications should the nurse instruct the client to discontinue 48 hours prior to the procedure?

• A. Atorvastatin
• B. Digoxin
• C. Nifedipine
• D. Metformin

Correct answer: D

Rationale: The correct answer is D, Metformin. Metformin should be discontinued 48 hours before an arteriogram due to the risk of lactic acidosis. Atorvastatin (Choice A) is a statin used to lower cholesterol levels and is not typically contraindicated before an arteriogram. Digoxin (Choice B) is a medication used for heart conditions and does not need to be discontinued before an arteriogram. Nifedipine (Choice C) is a calcium channel blocker used to treat high blood pressure and angina, and it is not necessary to discontinue before the procedure.

5. A client who is at 12 weeks of gestation and has hyperemesis gravidarum is being cared for by a nurse. Which of the following laboratory values should the nurse report to the provider?

• A. Sodium 140 mEq/L
• B. Potassium 3.8 mEq/L
• C. Blood glucose 90 mg/dL
• D. Urine ketones present

Correct answer: D

Rationale: The correct answer is D: Urine ketones present. The presence of urine ketones indicates dehydration and inadequate glucose control in clients with hyperemesis gravidarum. Reporting this finding to the provider is crucial for prompt intervention to prevent further complications. Choices A, B, and C are within normal ranges and do not directly correlate with the condition of hyperemesis gravidarum. Therefore, they are not the priority values to report in this scenario.
