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 assessing a client with pneumonia who is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client's respiratory rate is 20 breaths per minute.
• B. The client's arterial blood gases show a pH of 7.35.
• C. The client's oxygen saturation is 92%.
• D. The client's breath sounds are clear.

Correct answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

3. 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.

4. The nurse is developing a program to educate parents on the importance of childhood immunizations. Which topic should be prioritized?

• A. the benefits of immunizations
• B. the potential side effects of vaccines
• C. the immunization schedule
• D. ways to comfort children during vaccinations

Correct answer: A

Rationale: The correct answer is A: the benefits of immunizations. Emphasizing the benefits of immunizations helps parents understand the importance of vaccines in protecting their children from preventable diseases. This choice should be prioritized as it focuses on the positive outcomes of immunizations, which can motivate parents to vaccinate their children. Choices B, C, and D are not the top priority because while it's important to address potential side effects, the immunization schedule, and comforting children during vaccinations, the main focus should be on highlighting the benefits to encourage parents to make informed decisions regarding their child's immunizations.

5. A client with a history of coronary artery disease is admitted with chest pain. Which finding requires immediate intervention?

• A. Heart rate of 90 beats per minute.
• B. Blood pressure of 130/80 mm Hg.
• C. Respiratory rate of 20 breaths per minute.
• D. Chest pain radiating to the left arm.

Correct answer: D

Rationale: The correct answer is D. Chest pain radiating to the left arm can be a sign of myocardial infarction (heart attack) and requires immediate intervention. This symptom is known as a classic presentation of a heart attack and warrants urgent medical attention to prevent further cardiac damage. Choices A, B, and C are not directly indicative of an acute cardiac event and may not require immediate intervention in this scenario. While heart rate, blood pressure, and respiratory rate are important vital signs to monitor, they do not specifically indicate the urgency associated with chest pain radiating to the left arm in a patient with a history of coronary artery disease.
