A nurse is preparing to administer vitamin K IM to a newborn. Into which of the following muscles should the nurse inject the medication?

Deltoid.

Dorsogluteal.

Ventrogluteal.

Vastus lateralis.

Answer and Explanation

The Correct Answer is D

The correct answer is choice d. Vastus lateralis.

Choice A rationale:

The deltoid muscle is not typically used for newborn injections because it is too small and underdeveloped, making it an inappropriate site for intramuscular injections in this age group.

Choice B rationale:

The dorsogluteal muscle is also not recommended for newborns due to the risk of injury to the sciatic nerve and the muscle’s underdevelopment.

Choice C rationale:

The ventrogluteal muscle, while a good site for older children and adults, is not commonly used for newborns because it is not as easily accessible and developed as the vastus lateralis.

Choice D rationale:

The vastus lateralis muscle, located on the anterolateral aspect of the thigh, is the preferred site for intramuscular injections in newborns. It is well-developed and provides a large muscle mass, making it the safest and most effective site for administering vitamin K.

Correct Answer is C

Explanation

Choice A rationale:

Preterm labor. Performing a pelvic examination in a client with placenta previa can potentially trigger uterine contractions, leading to preterm labor. Manipulating the cervix during the examination may stimulate the release of hormones that could initiate labor, putting both the mother and the baby at risk.

Choice B rationale:

Infection. While infection is a valid concern in any medical procedure, it is not the primary rationale for avoiding a pelvic examination in a client with placenta previa. The primary concern is the risk of severe bleeding caused by the disruption of the placenta's attachment to the uterine wall.

Choice C rationale:

Profound bleeding. The primary rationale to avoid a pelvic examination in a client with placenta previa is the risk of profound bleeding. Placenta previa occurs when the placenta covers part or all of the cervix, and it is at risk of being damaged or detached during a pelvic exam. This can lead to life-threatening hemorrhage for both the mother and the baby.

Choice D rationale:

Rupture of the fetal membranes. While this complication is possible during a pelvic examination, it is not the primary rationale to avoid the procedure in a client with placenta previa. The main concern, as mentioned before, is the risk of severe bleeding that can occur due to placental disruption.

A. The client is Rh positive and the newborn is Rh negative. B. The client is Rh negative and the newborn is Rh positive. C. The client is Rh negative and the newborn is Rh negative. D. The client is Rh positive and the newborn is Rh positive.

Correct Answer is B

Explanation

Choice A rationale:

If the client is Rh positive and the newborn is Rh negative, there is no indication for administering Rho(D) immune globulin. Rho(D) immune globulin is only given when the Rh-negative mother gives birth to an Rh-positive baby.

Choice B rationale:

This is the correct choice for administering Rho(D) immune globulin. When the mother is Rh negative and the newborn is Rh positive, there is a risk of Rh incompatibility. If the fetal blood enters the mother's circulation during delivery, her immune system may produce antibodies against Rh-positive blood cells, which can be harmful to future Rh-positive pregnancies. To prevent this, Rho(D) immune globulin is administered to the Rh-negative mother shortly after delivery.

Choice C rationale:

If both the mother and the newborn are Rh-negative, there is no risk of Rh incompatibility. Rho(D) immune globulin is not required in this situation.

Choice D rationale:

If both the mother and the newborn are Rh-positive, there is no risk of Rh incompatibility. Rho(D) immune globulin is not indicated in this case.
