A child weighing 55 lb has been prescribed cefotaxime at a dosage of 150 mg/kg/day, to be administered in divided doses every 6 hours.

How many mg should the nurse administer each day? (Provide a numerical value only.)

Answer and Explanation

The Correct Answer is ["3742"]

Step 1 is: Convert the child’s weight from pounds to kilograms. 1 pound is approximately 0.453592 kilograms, so 55 lb × 0.453592 kg/lb = 24.9476 kg.

Step 2 is: Calculate the total daily dosage. 150 mg/kg/day × 24.9476 kg = 3742.14 mg/day. Therefore, the nurse should administer approximately 3742 mg each day when rounded to the nearest whole number.

Correct Answer is B

Explanation

Choice A rationale

While placing a certified copy of the living will in the patient’s record is important, it is not the immediate next step. The living will should be acknowledged, but the healthcare provider needs to be informed immediately.

Choice B rationale

Informing the healthcare provider of the patient’s wishes is the most appropriate next step. The healthcare provider can then make decisions based on the patient’s expressed wishes.

Choice C rationale

Arranging a family meeting with the palliative care team may be beneficial, but it is not the immediate next step. The healthcare provider needs to be informed first.

Choice D rationale

Notifying the nursing staff of the patient’s do not resuscitate status is important, but it is not the immediate next step. The healthcare provider needs to be informed first.

A. Apply ice, then a warm compress to the IV site. B. Check the medical record for the date of IV insertion. C. Redress the IV site while checking for redness. D. Discontinue the current IV site and insert a new one.

Correct Answer is D

Explanation

Choice A rationale

Applying ice, then a warm compress to the IV site may help with pain or inflammation, but it does not address the potential problem with the IV site itself. If the client is experiencing pain and refuses a flush to assess the site, it could indicate that the IV site is compromised.

Choice B rationale

Checking the medical record for the date of IV insertion could provide useful information about how long the IV has been in place, but it does not directly address the client’s current complaint of pain at the IV site.

Choice C rationale

Redressing the IV site while checking for redness could help identify signs of infection or inflammation, but it does not address the client’s complaint of pain or their refusal to have the site flushed.

Choice D rationale

Discontinuing the current IV site and inserting a new one is the most appropriate action in this situation. If the client is experiencing pain at the IV site and refuses a flush to assess the site, it suggests that the current IV site may be compromised. Inserting a new IV ensures that the client can continue to receive their scheduled IV medication safely.
