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. Turn the patient on their side before starting oral care. B. Apply petroleum jelly to the patient’s lips after oral care. C. Use the thumb and index finger to keep the patient’s mouth open. D. Use a stiff toothbrush to clean the patient’s teeth.

Correct Answer is A

Explanation

Choice A rationale
Turning the patient on their side before starting oral care is a recommended practice when caring for an unresponsive patient. This position helps prevent aspiration, which can occur if the patient cannot swallow properly.
Choice B rationale
Applying petroleum jelly to the patient’s lips after oral care can help prevent dryness and cracking. However, it’s not the primary action the nurse should take when performing oral hygiene for an unresponsive patient.
Choice C rationale
Using the thumb and index finger to keep the patient’s mouth open is not recommended. It can cause discomfort and potential injury to the patient.
Choice D rationale
Using a stiff toothbrush to clean the patient’s teeth is not recommended. A soft toothbrush is usually used to clean the teeth of an unresponsive patient to prevent damage to the gums.
