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 ["2 ."]

Explanation

Step 1: Identify the prescribed dose and the available dose. The prescribed dose is 500 mg and the available dose is 250 mg per tablet.

Step 2: Use the formula for calculating the number of tablets: (Prescribed dose ÷ Available dose) = Number of tablets.
Step 3: Substitute the values into the formula: (500 mg ÷ 250 mg/tablet) = 2 tablets. So, the nurse should administer 2 tablets.

A. Request a prescription for the insertion of an indwelling urinary catheter. B. Apply a moisture barrier ointment to the skin. C. Clean the skin and perineum with hot water after each episode of incontinence. D. Check the client’s skin every 8 hours for signs of breakdown. E. Check the client’s skin every 8 hours for signs of breakdown.

Correct Answer is B

Explanation

Choice A rationale
Requesting a prescription for the insertion of an indwelling urinary catheter is not the best option to prevent skin breakdown in a client with urinary incontinence. Catheters can increase the risk of urinary tract infections and should be used as a last resort.
Choice B rationale

Applying a moisture barrier ointment to the skin can help protect the skin from the damaging effects of urine. This can help prevent skin breakdown and is a common practice in the care of clients with urinary incontinence.
Choice C rationale
Cleaning the skin and perineum with hot water after each episode of incontinence is not recommended. Hot water can dry out the skin and cause irritation. It’s better to use warm water and a gentle cleanser.
Choice D rationale
Checking the client’s skin every 8 hours for signs of breakdown is important, but it’s not the only action the nurse should take. The nurse should also take proactive measures to protect the skin, such as applying a moisture barrier ointment.
