A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?
3000 mg.
3300 mg.
3600 mg.
3750 mg.
The Correct Answer is D
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).
Step 2 is to calculate the total daily dosage. The prescription is for 150 mg/kg/day. So, the total daily dosage is 150 mg/kg/day × 25 kg = 3750 mg/day.
So, the correct answer is, after analysing all choices, the nurse should administer 3750 mg of cefotaxime each day.

Correct Answer is A
Explanation
Choice A rationale:
Observing for signs of depression is the most important intervention for the nurse to include in the client's plan of care. This patient has a history of struggling with weight management, diabetes mellitus, and hypertension, and is now approved for gastroplasty. Weight management surgery can have significant psychological implications, and patients may experience depression or other emotional issues. Identifying signs of depression and providing appropriate support and resources is crucial for the client's overall well-being and successful outcomes.
Choice B rationale:
Monitoring for urinary incontinence is not the top priority in this case. While it's important to assess and address urinary incontinence when necessary, it is not the most critical concern for a client undergoing gastroplasty. Depression and post-surgical complications related to weight management surgery take precedence.
Choice C rationale:
Providing a wide variety of meal choices is not the most important intervention at this stage. After gastroplasty, dietary choices are typically restricted, and the focus is on a controlled and healthy diet. The priority is addressing the psychological and emotional aspects of the client's care, as well as monitoring for surgical complications.
Choice D rationale:
Applying sequential compression stockings is not the most crucial intervention in this situation. While prophylaxis against deep vein thrombosis (DVT) is important, it is not the top priority compared to addressing potential depression and emotional well-being in a client who has struggled with weight management for years.
Correct Answer is C
Explanation
Choice A rationale:
Ketonuria is not a common complication of diabetes insipidus. Ketonuria is associated with diabetes mellitus, a different condition that results in the accumulation of ketones in the urine due to insufficient insulin.
Choice B rationale:
Peripheral edema is also an unlikely complication of diabetes insipidus. Diabetes insipidus is characterized by excessive thirst and urination, not fluid retention or peripheral edema.
