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 D

Explanation

Choice A rationale
Tachycardia is not a common adverse effect of oxygen therapy. It is more likely to be associated with conditions such as fever, anemia, or hypoxia.
Choice B rationale
Poor skin turgor is a sign of dehydration, not a typical adverse effect of oxygen therapy. Oxygen therapy does not directly affect the body’s hydration status.
Choice C rationale
Excessive pulmonary secretions are not a direct adverse effect of oxygen therapy. Conditions such as pneumonia or bronchitis often cause increased secretions.

Choice D rationale
Cracks in the oral mucous membranes can occur as a result of oxygen therapy. Oxygen can dry out the mucous membranes, leading to discomfort and potential cracking.

A. Place a 1-inch needle on the syringe. B. Hold the syringe at a 20° angle to the client’s skin. C. Draw up 0.5 mL of purified protein derivative (PPD) from the vial. D. Pinch the skin at the chosen site with the non-dominant hand before inserting the needle.

Correct Answer is C

Explanation

Choice A rationale
Placing a 1-inch needle on the syringe is not appropriate for an intradermal injection such as a tuberculin skin test. Intradermal injections require a much shorter needle, typically 1/4 to 1/2 inch in length.
Choice B rationale
Holding the syringe at a 20° angle to the client’s skin is not correct for an intradermal injection. For an intradermal injection, the syringe should be held at a much shallower angle, typically about 5 to 15 degrees.
Choice C rationale

Drawing up 0.1 mL of purified protein derivative (PPD) from the vial is the correct action when preparing to administer a tuberculin skin test. This is the standard amount of PPD used for a tuberculin skin test.
Choice D rationale
Pinching the skin at the chosen site with the non-dominant hand before inserting the needle is not typically done for an intradermal injection. Instead, the skin is usually stretched taut to provide a flat surface for the injection.
