Nursing Elites

1. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A nurse is caring for a client who is 36 weeks pregnant and reports leaking fluid. Which of the following tests should the nurse use to confirm that the client's membranes have ruptured?

• A. Nonstress test
• B. Biophysical profile
• C. Fern test
• D. Amniocentesis

Correct answer: C

Rationale: The correct answer is the Fern test. The Fern test is specifically used to confirm the rupture of membranes. A sample of vaginal fluid is examined under a microscope, and the presence of a fern-like pattern indicates the presence of amniotic fluid. The Nonstress test (Choice A) is used to monitor fetal heart rate and movement, not to confirm ruptured membranes. The Biophysical profile (Choice B) is a prenatal ultrasound evaluation to assess fetal well-being, not to confirm ruptured membranes. Amniocentesis (Choice D) involves the aspiration of amniotic fluid for various diagnostic purposes, not specifically to confirm ruptured membranes.

3. A nurse is caring for a client who is receiving oxytocin to augment labor. The client has an intrauterine pressure catheter and an internal fetal scalp electrode for monitoring. Which of the following is an indication that the nurse should discontinue the infusion?

• A. Contraction frequency every 3 minutes
• B. Contraction duration of 100 seconds
• C. Fetal heart rate with moderate variability
• D. Fetal heart rate of 118/min

Correct answer: B

Rationale: A contraction duration of 100 seconds indicates potential uterine hyperstimulation, which can lead to fetal distress and decreased uterine perfusion. Prolonged contractions may reduce oxygen supply to the fetus, putting it at risk. Discontinuing the oxytocin infusion is crucial to prevent adverse effects on both the mother and the fetus. The other options do not raise immediate concerns that would necessitate discontinuing the oxytocin infusion. Contraction frequency every 3 minutes is within a normal range. Fetal heart rate with moderate variability and a rate of 118/min are both reassuring signs of fetal well-being.

4. A nurse is reviewing the guidelines for reporting nationally notifiable infectious diseases. What disease should the nurse report to the CDC?

• A. Measles
• B. Hepatitis A
• C. Lyme disease
• D. Zika

Correct answer: C

Rationale: The correct answer is Lyme disease. Lyme disease must be reported to the CDC as it is a nationally notifiable infectious disease. It is spread by ticks and can lead to significant health issues if not monitored. Measles, Hepatitis A, and Zika are also important infectious diseases, but in this case, Lyme disease is the appropriate choice based on the information provided.

5. A healthcare professional is assessing a client with hepatic encephalopathy. Which of the following foods indicates understanding of dietary teaching?

• A. Cottage cheese
• B. Tuna salad
• C. Rice with black beans
• D. Three-egg omelet

Correct answer: C

Rationale: The correct answer is C: 'Rice with black beans.' Plant-based proteins such as beans are recommended for clients with hepatic encephalopathy to reduce ammonia production from animal proteins. Cottage cheese (choice A), tuna salad (choice B), and a three-egg omelet (choice D) are high in animal proteins, which can contribute to increased ammonia levels in hepatic encephalopathy, making them less suitable dietary choices for these clients.
