C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.

D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.

Correct Answer is A,C,B

Explanation

Here’s the correct sequence for administering ceftriaxone using the Z-track technique: 1. Use the nondominant hand to pull the skin and subcutaneous tissue 2.5 cm (1 in) laterally. 2. Aspirate by pulling back on the plunger and inject the medication. 3. Remove the needle and release the tissue. This method helps to prevent the medication from leaking into the subcutaneous tissue, reducing irritation and discomfort.

A. Have an assistive personnel feed the client. B. Apply foam handles to the client's eating utensils. C. Obtain a referral for physical therapy. D. Ask the provider for a prescription for a pureed diet.

Correct Answer is B

Explanation

Apply foam handles to the client's eating utensils. This intervention can help the client grip the utensils better and improve their ability to eat.

Reasons why the other options are not answers:

Option A: Having an assistive personnel feed the client may decrease the client's autonomy.

Option C: Obtaining a referral for physical therapy may be helpful but does not address the immediate issue of difficulty with eating.

Option D: Asking the provider for a prescription for a pureed diet may not be necessary or desirable at this time.
