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.
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 determine how many mL to administer. The client needs 300 mg of amoxicillin and the available medication is 250 mg/5 mL. So, the calculation is (300 mg ÷ 250 mg/mL) × 5 mL.
Step 2 is to perform the calculation. The result is 6 mL.
Correct Answer is B
Explanation
Choice A rationale
While it’s true that a nasal cannula allows the patient to remove it for a while when it gets uncomfortable, this is not the primary reason for using a nasal cannula. The main purpose of a nasal cannula is to deliver oxygen.
Choice B rationale
A nasal cannula delivers the low concentration of oxygen that the patient needs. It is designed to provide a specific amount of oxygen, and the flow rate can be adjusted as needed.
Choice C rationale
While a nasal cannula does deliver a specific concentration of oxygen, it does not do so constantly. The amount of oxygen delivered can vary depending on the patient’s breathing rate and depth.
Choice D rationale
A nasal cannula does not deliver the highest concentration of oxygen possible. Other devices, such as non-rebreather masks, can deliver higher concentrations of oxygen.
