A nurse is preparing to administer vitamin K intramuscularly to a newborn. Which of the following muscles should the nurse use for the injection?

Deltoid.

Ventrogluteal.

Dorsogluteal.

Vastus lateralis.

Answer and Explanation

The Correct Answer is D

Choice A rationale
The deltoid muscle is not typically used for injections in newborns. It is not as developed as the vastus lateralis and does not have as much muscle mass.

Choice B rationale
The ventrogluteal muscle is generally not used for injections in newborns. It is not as accessible or as well developed as the vastus lateralis.
Choice C rationale
The dorsogluteal muscle is not recommended for injections in newborns due to the risk of damaging the sciatic nerve.
Choice D rationale
The vastus lateralis muscle is the preferred site for intramuscular injections in newborns. It is the most developed muscle in this age group and is free of major nerves and blood vessels.

Correct Answer is C

Explanation

Step 1 is to calculate the amount of amoxicillin in milliliters. Step 2: We know that 250 mg of amoxicillin is in 5 mL.
Step 3: We need to find out how many mL contain 350 mg of amoxicillin. Step 4: Set up a proportion: 250 mg/5 mL = 350 mg/x mL.
Step 5: Cross-multiply and solve for x: 250x = 1750. Step 6: Divide both sides by 250: x = 7 mL2.

A. Prepare to administer antibiotics. B. Instruct the client to limit fluid intake to less than 2,000 m/day. C. Initiate bedrest in semi-Fowler’s position. D. Repeat the auscultation after asking the client to breathe deeply and cough.

Correct Answer is D

Explanation

Choice A rationale
While antibiotics are used to treat bacterial infections, crackles in the lungs can be a sign of various conditions, not just bacterial infections. Therefore, administering antibiotics is not the appropriate action based solely on the finding of crackles.
Choice B rationale

Limiting fluid intake can be beneficial for clients with certain conditions such as heart failure, but it is not the appropriate action based solely on the finding of crackles.
Choice C rationale
Initiating bedrest in semi-Fowler’s position can help improve lung expansion and ease breathing in clients with certain respiratory conditions. However, it is not the appropriate action based solely on the finding of crackles.
Choice D rationale
Crackles can sometimes be cleared by deep breathing and coughing. Repeating the auscultation after asking the client to breathe deeply and cough can help the nurse determine if the crackles are transient (cleared by coughing) or persistent.
