Nursing Elites

1. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

2. A client with a history of myocardial infarction (MI) is prescribed nitroglycerin (Nitrostat) for chest pain. Which instruction should the nurse provide?

• A. Take the medication with food.
• B. Swallow the tablet whole.
• C. Take the medication at bedtime.
• D. Place the tablet under your tongue.

Correct answer: D

Rationale: The correct instruction for a client prescribed nitroglycerin (Nitrostat) for chest pain is to place the tablet under the tongue. This route allows for rapid absorption of the medication, providing quick relief for chest pain associated with myocardial infarction.

3. A 65-year-old female client arrives in the emergency department with shortness of breath and chest pain. The nurse accidentally administers 10 mg of morphine sulfate instead of the prescribed 4 mg. Later, the client's respiratory rate is 10 breaths/minute, oxygen saturation is 98%, and she states her pain has subsided. What is the legal status of the nurse?

• A. The nurse is guilty of negligence and will be sued.
• B. The client would not be able to prove malpractice in court.
• C. The nurse is protected by the Good Samaritan Act.
• D. The healthcare provider should have given the morphine sulfate dose.

Correct answer: B

Rationale: The correct answer is B because, in this scenario, the client would not be able to prove malpractice in court. Despite the nurse administering a higher dose of morphine than prescribed, the client's respiratory rate, oxygen saturation, and pain relief indicate that no harm resulted from the error. Therefore, the client would not have legal grounds to pursue a malpractice case against the nurse.

4. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of citrus fruits.
• D. Avoid high-sodium foods.

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

5. The community health nurse is working in a multi-ethnic health center. In what situation should the nurse intervene?

• A. An Asian-American mother reports using cupping to treat an infection, resulting in a pattern of red round marks on her toddler's back.
• B. A Hispanic pregnant client who is often late for appointments arrives late for today's appointment.
• C. A Native-American individual being interviewed will not make direct eye contact when asked about violence in the home.
• D. An African-American infant who is spitting up milk has lost 6 ounces since last week's clinic visit.

Correct answer: D

Rationale: The correct answer is D because losing weight in an infant, especially when combined with spitting up milk, requires immediate intervention to address potential health concerns. Choice A deals with a cultural practice that may not necessarily pose an immediate health risk. Choice B, while important, does not present an immediate health threat. Choice C relates to cultural differences in communication and does not necessarily indicate a need for immediate intervention in terms of health.
