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 B
Explanation
Choice A rationale:
Reducing the client's interaction with others during the day is not the most appropriate approach in this situation. It may lead to increased social isolation and worsen the client's agitation and delusions. It does not address the client's emotional distress.
Choice B rationale:
Using distraction and therapeutic communication skills is the most suitable approach for a client with dementia who is experiencing agitation and delusional thoughts. Distraction techniques can help redirect the client's focus away from distressing thoughts, and therapeutic communication skills, such as active listening and validation, can help the client feel understood and supported.
Choice C rationale:
Awakening the client earlier for daily morning care may further disrupt the client's sleep patterns and worsen agitation. It does not address the underlying issue of delusional thoughts and the client's emotional distress.
Choice D rationale:
Clarifying reality with the client about delusional thoughts can be counterproductive in dementia care. The client's cognitive impairment may make it challenging for them to understand or accept the clarification, leading to increased frustration and agitation. It is essential to use a more empathetic and therapeutic approach.
Correct Answer is C
Explanation
When assessing an older client with left-sided heart failure (HF), the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. Left-sided heart failure is characterized by the inability of the left ventricle to effectively pump blood, leading to fluid accumulation in the lungs. Auscultating all lung fields allows the PN to assess for the presence of abnormal lung sounds such as crackles, indicating pulmonary congestion.
Let's evaluate the other options:
a) Inspect for sacral edema.
Sacral edema is commonly associated with right-sided heart failure, not left-sided heart failure. While it is important to assess for edema in clients with heart failure, inspecting for sacral edema may not be the most immediate and crucial intervention in this specific case.
b) Measure urinary output.
Measuring urinary output is a valuable assessment in many clinical situations, but it may not be the most vital intervention in the context of left-sided heart failure. Monitoring urinary output is more relevant in assessing kidney function and fluid balance rather than directly assessing the severity of left-sided heart failure.
d) Check mental acuity.
Checking mental acuity is important in assessing the overall condition of the client, but it is not the most crucial intervention specifically related to left-sided heart failure. Mental status evaluation is more useful in identifying signs of altered mental status or potential complications, rather than directly assessing the impact of left-sided heart failure.
In summary, when assessing an older client with left-sided heart failure, the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. This allows for the detection of abnormal lung sounds associated with pulmonary congestion, a hallmark sign of left-sided heart failure.
