A nurse is preparing to administer vitamin
K. Which of the following muscles should the nurse consider for the injection?

Deltoid

Vastus lateralis

Ventrogluteal

Dorsogluteal .

Answer and Explanation

The Correct Answer is B

Choice A rationale
The deltoid muscle is not typically used for intramuscular injections in infants due to its small size.

Choice B rationale
The vastus lateralis muscle is one of the preferred sites for intramuscular injections in infants, including the vitamin K injection. This muscle is large enough to absorb the medication, and injections here carry less risk of hitting a nerve or blood vessel.
Choice C rationale
The ventrogluteal muscle is not typically used for intramuscular injections in infants. This site is often used in older children and adults.
Choice D rationale
The dorsogluteal site is not recommended for intramuscular injections due to the risk of damaging the sciatic nerve.

Correct Answer is D

Explanation

Choice A rationale

Hypomagnesemia is not typically a primary concern for newborns of mothers with diabetes mellitus. While it can occur in newborns, it is not directly related to macrosomia or maternal diabetes.
Choice B rationale
Hypocalcemia can occur in newborns, especially preterm infants, infants of diabetic mothers, and those with perinatal asphyxia. However, it is not the primary concern in this scenario.
Choice C rationale
Hyperbilirubinemia can occur in newborns for a variety of reasons, including prematurity, blood group incompatibility, and other factors. While infants of diabetic mothers may have an increased risk of jaundice, it is not the primary concern in this scenario.
Choice D rationale
Hypoglycemia is the correct answer. Infants of diabetic mothers are at risk for hypoglycemia after birth. During pregnancy, the fetus produces extra insulin in response to the mother’s high blood glucose levels. After birth, the newborn continues to produce extra insulin for a short time until it adjusts to normal glucose-insulin balance. This can lead to hypoglycemia, which is a primary concern and requires immediate attention.

A. Spontaneous rupture of membranes. B. Uteroplacental insufficiency. C. Altered fetal cerebral blood flow. D. Umbilical cord compression.

Correct Answer is A

Explanation

Choice A rationale
Early decelerations in the fetal heart rate (FHR) are caused by compression of the fetus’s head during a uterine contraction. This often happens during later stages of labor as the baby is descending through the birth canal. They may also occur during early labor if the baby is premature or in a breech position. This causes the uterus to squeeze the head during contractions.
Choice B rationale
Uteroplacental insufficiency is a condition where the placenta does not provide enough oxygen and nutrients to the fetus. This condition is typically associated with late decelerations in the FHR, not early decelerations.
Choice C rationale
Altered fetal cerebral blood flow is not typically associated with early decelerations in the FHR34.
Choice D rationale

Umbilical cord compression is typically associated with variable decelerations in the FHR, not early decelerations.
