1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). The nurse should monitor the client for which of the following laboratory values?
- A. Prothrombin time (PT)
- B. Serum potassium
- C. Blood urea nitrogen (BUN)
- D. White blood cell count (WBC)
Correct answer: A
Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.
2. A healthcare professional is providing care to a client who has a tracheostomy. Which of the following actions should the professional take to prevent complications?
- A. Clean around the stoma with povidone-iodine.
- B. Maintain sterile technique when performing tracheostomy care.
- C. Use clean technique when suctioning the tracheostomy.
- D. Change tracheostomy ties weekly.
Correct answer: B
Rationale: Maintaining sterile technique when performing tracheostomy care is essential in preventing infections and complications. Option A is incorrect because povidone-iodine may be too harsh for cleaning around the stoma and can lead to skin irritation. Option C is incorrect because suctioning a tracheostomy should be done using sterile technique to minimize the risk of introducing pathogens. Option D is incorrect as tracheostomy ties need to be changed more frequently, usually every 1-2 days, to prevent skin breakdown and infection.
3. The nurse is caring for an infant with candidal diaper rash. Which topical agent would the nurse expect the healthcare provider to order?
- A. Corticosteroids.
- B. Antifungals.
- C. Antibiotics.
- D. Retinoids.
Correct answer: B
Rationale: Antifungal agents are the appropriate treatment for candidal diaper rash as it is a fungal infection. Corticosteroids, antibiotics, and retinoids are not indicated for this condition. Corticosteroids may worsen fungal infections, antibiotics are used for bacterial infections, and retinoids are typically used for acne and skin conditions unrelated to candidal diaper rash.
4. Which type of isolation is required for a patient with measles?
- A. Contact isolation
- B. Airborne isolation
- C. Droplet isolation
- D. Reverse isolation
Correct answer: B
Rationale: The correct answer is B: Airborne isolation. Measles is highly contagious and can be transmitted through airborne particles, so airborne isolation is necessary to prevent its spread. Choice A, Contact isolation, is incorrect because measles is not primarily transmitted through direct contact. Choice C, Droplet isolation, is also incorrect as measles is not transmitted through large droplets but through smaller airborne particles. Choice D, Reverse isolation, is used to protect a patient from outside infections, not to prevent the spread of a contagious disease like measles.
5. During a routine prenatal visit, a nurse measures a client’s fundal height at 26 weeks gestation. What should the fundal height be?
- A. Approximately 26 cm
- B. Between 24 to 28 cm
- C. Above the umbilicus by two finger widths
- D. Below the xiphoid process
Correct answer: B
Rationale: The correct answer is B: 'Between 24 to 28 cm.' Fundal height is expected to be approximately equal to the weeks of gestation, so at 26 weeks, the fundal height should typically range between 24 to 28 cm. Choice A is incorrect because fundal height is not an exact measurement of gestational age in centimeters. Choice C is incorrect as it provides a general description above the umbilicus, which is not specific to 26 weeks gestation. Choice D is incorrect as the fundal height would not reach below the xiphoid process at 26 weeks gestation.
