Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. The nurse is providing discharge teaching to a client with a new diagnosis of diabetes mellitus. Which statement by the client indicates a need for further teaching?

• A. I will need to monitor my blood sugar levels daily.
• B. I will follow a diet low in carbohydrates.
• C. I will rotate the injection sites for my insulin.
• D. I will exercise regularly to help manage my diabetes.

Correct answer: B

Rationale: The correct answer is B. The statement 'I will follow a diet low in carbohydrates' indicates a need for further teaching. In diabetes mellitus, it is essential to follow a balanced diet that includes carbohydrates, proteins, and fats. Carbohydrates are a major source of energy and should be included in moderation to help manage blood sugar levels. Monitoring blood sugar levels daily (A), rotating injection sites for insulin (C), and exercising regularly (D) are all appropriate self-management strategies for individuals with diabetes mellitus.

3. A community health nurse is evaluating the effectiveness of a recent smoking cessation program. Which outcome indicates success?

• A. increased attendance at support group meetings
• B. reduced number of cigarettes smoked per day
• C. higher sales of nicotine replacement products
• D. lower relapse rate among participants

Correct answer: D

Rationale: The correct answer is D: lower relapse rate among participants. A lower relapse rate indicates that participants are successfully quitting smoking and maintaining their cessation, which is the ultimate goal of a smoking cessation program. Increased attendance at support group meetings (choice A) may demonstrate engagement but does not necessarily indicate successful smoking cessation. Similarly, higher sales of nicotine replacement products (choice C) may reflect increased product usage but not necessarily successful smoking cessation. While reducing the number of cigarettes smoked per day (choice B) is a positive change, it does not guarantee successful smoking cessation or long-term abstinence.

4. A client with a history of myocardial infarction is prescribed aspirin therapy. Which instruction should the nurse include in the client's teaching plan?

• A. Take aspirin with food.
• B. Take aspirin at the same time every day.
• C. Avoid taking aspirin with alcohol.
• D. Discontinue aspirin if you experience ringing in your ears.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the client's teaching plan is to avoid taking aspirin with alcohol. Combining aspirin with alcohol can increase the risk of gastrointestinal bleeding and other complications. Taking aspirin with food helps reduce stomach upset, but it is not the most crucial instruction in this scenario. While taking aspirin at the same time every day can help with consistency, it is not as critical as avoiding alcohol. Discontinuing aspirin if experiencing ringing in the ears is important to address potential side effects, but it is not directly related to preventing complications when combining with alcohol.

5. A client with a history of hypertension is admitted with a blood pressure of 200/120 mm Hg. Which medication should the nurse prepare to administer?

• A. Metoprolol (Lopressor).
• B. Furosemide (Lasix).
• C. Lisinopril (Zestril).
• D. Nitroprusside (Nipride).

Correct answer: D

Rationale: The correct answer is D, Nitroprusside (Nipride). In this scenario of severe hypertension (200/120 mm Hg), a hypertensive emergency is present, requiring rapid reduction of blood pressure. Nitroprusside is a vasodilator that acts quickly to lower blood pressure in such emergencies. Options A, B, and C are incorrect: A) Metoprolol is a beta-blocker that lowers blood pressure but is not indicated for hypertensive emergencies requiring rapid reduction. B) Furosemide is a diuretic that helps with fluid retention but does not rapidly lower blood pressure. C) Lisinopril is an ACE inhibitor used for long-term management of hypertension, not for immediate reduction in hypertensive emergencies.
