Nursing Elites

1. A client prescribed warfarin is being taught about dietary modifications by a nurse. Which statement by the client indicates understanding of the teaching?

• A. ''I need to avoid foods high in vitamin C.''
• B. ''I should eat a consistent amount of vitamin K each day.''
• C. ''I can eat as many leafy greens as I want.''
• D. ''I should not worry about any changes in my diet.''

Correct answer: B

Rationale: The correct answer is B. Consistency in vitamin K intake is crucial for clients on warfarin to maintain stable anticoagulation levels. Option A is incorrect as vitamin C does not directly interact with warfarin. Option C is incorrect because although leafy greens are high in vitamin K, excessive consumption can affect warfarin's effectiveness. Option D is incorrect as any changes in diet, particularly in vitamin K intake, can impact the efficacy of warfarin.

2. A client in the intensive care unit is being mechanically ventilated, has an indwelling urinary catheter in place, and is exhibiting signs of restlessness. Which action should the nurse take first?

• A. Review the heart rhythm on cardiac monitors
• B. Check urinary catheter for obstruction
• C. Auscultate bilateral breath sounds
• D. Give PRN dose of lorazepam (Ativan)

Correct answer: B

Rationale: When a client in the intensive care unit is mechanically ventilated, has an indwelling urinary catheter, and is restless, the priority action is to check the urinary catheter for obstruction. Restlessness in this context could be due to a blocked catheter causing discomfort or urinary retention, which needs immediate attention to prevent complications. Reviewing the heart rhythm on cardiac monitors can be important but is not the priority in this scenario. Auscultating bilateral breath sounds is also important in a ventilated client but addressing the potential immediate issue of a blocked catheter takes precedence. Giving a PRN dose of lorazepam should not be the first action without addressing the underlying cause of restlessness.

3. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?

• A. 18
• B. 27
• C. 36
• D. 45

Correct answer: D

Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.

4. The client demonstrates an understanding of sliding scale insulin administration instructions by performing the procedure in which order?

• A. Obtain blood glucose level
• B. Verify the insulin prescription
• C. Draw insulin into insulin syringe
• D. Cleanse the selected site

Correct answer: A

Rationale: The correct order for the client to perform the procedure is to first obtain the blood glucose level. This step is crucial as it helps determine the appropriate dose of insulin based on the sliding scale. Verifying the insulin prescription, drawing insulin into the syringe, and cleansing the selected site are important steps in the process but should follow after obtaining the blood glucose level. Therefore, options B, C, and D are incorrect in terms of the initial steps required for sliding scale insulin administration.

5. The parents of a child who had surgical repair of a myelomeningocele are being taught how to change an occlusive dressing on the child’s back. Which statement by the parents indicates that they understand this procedure?

• A. When changing the dressing, the tape should be removed slowly to prevent trauma to the skin
• B. To prevent infection, the dressing should be kept dry to avoid excess moisture
• C. The skin incision should be kept moist to promote healing and prevent dryness
• D. The incision should be protected from fecal contamination by an intact dressing

Correct answer: D

Rationale: The correct answer is D because protecting the incision from fecal contamination is essential to prevent infection and promote healing in a child with a myelomeningocele. This is crucial as fecal matter can introduce harmful bacteria to the wound. Choice A is incorrect as removing the tape slowly to prevent trauma to the skin is a general guideline but not specific to preventing infection. Choice B is incorrect because keeping the dressing dry can lead to complications as the wound needs a moist environment to heal properly. Choice C is incorrect as keeping the skin incision moist may promote infection and delay healing, making it an incorrect statement for postoperative care.
