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 healthcare professional is assessing a client for signs of anaphylaxis. Which of the following findings should the healthcare professional look for?

• A. Bradycardia
• B. Hypotension
• C. Increased appetite
• D. Decreased respiratory rate

Correct answer: B

Rationale: Hypotension is a critical sign of anaphylaxis. During anaphylaxis, there is a widespread vasodilation leading to a drop in blood pressure, which manifests as hypotension. This can be accompanied by other symptoms such as swelling, difficulty breathing, hives, and itching. Bradycardia (choice A) is not typically associated with anaphylaxis; instead, tachycardia is more common due to the body's response to the allergic reaction. Increased appetite (choice C) is unrelated to anaphylaxis, as individuals experiencing anaphylaxis often feel unwell and may have nausea or vomiting. Decreased respiratory rate (choice D) is also not a typical finding in anaphylaxis; instead, respiratory distress and wheezing are more commonly observed.

3. 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.

4. A postpartum complication a client is at risk for is deep-vein thrombosis. Which of the following factors is strongly associated with this postpartum complication?

• A. Cesarean birth
• B. Vaginal birth
• C. Anemia
• D. Multiparity

Correct answer: A

Rationale: The correct answer is A: Cesarean birth. Cesarean birth doubles the risk for deep-vein thrombosis (DVT) due to immobility and vascular changes associated with surgery. Other risk factors for DVT include smoking, obesity, and a history of thromboembolism. Vaginal birth, anemia, and multiparity are not strongly associated with an increased risk of deep-vein thrombosis postpartum. It is important to educate clients undergoing cesarean birth about the increased risk of DVT and measures to prevent it, such as early ambulation and the use of compression stockings.

5. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following assessment findings requires immediate intervention by the nurse?

• A. Prealbumin level of 20 mg/dL
• B. Weight increase of 2 kg/day
• C. Temperature of 37.6°C
• D. Blood glucose level of 120 mg/dL

Correct answer: B

Rationale: A rapid weight gain of 2 kg/day suggests fluid overload, a possible complication of TPN. This requires immediate intervention to prevent further complications such as pulmonary edema. The other options are not indicative of immediate complications related to TPN. A low prealbumin level may indicate malnutrition but does not require immediate intervention. A slightly elevated temperature and blood glucose level are within normal ranges and do not warrant immediate action.
