A nurse is planning to administer Rh(D) immune globulin to a client who is postpartum.Which of the following actions should the nurse take?
Verify that the newborn is Rh-negative.
Verify that the client’s Coombs test is positive.
Administer the medication within 72 hours after birth.
Administer the medication into the client’s abdomen.
The Correct Answer is C
Choice A rationale
Verifying that the newborn is Rh-negative is not necessary for administering Rh(D) immune globulin. The medication is given to Rh-negative mothers to prevent Rh sensitization, regardless of the newborn’s Rh status.
Choice B rationale
A positive Coombs test indicates that the mother has already been sensitized to Rh-positive blood cells, making Rh(D) immune globulin ineffective in preventing sensitization.
Choice C rationale
Administering Rh(D) immune globulin within 72 hours after birth is crucial to prevent Rh sensitization in future pregnancies. This timing ensures that the mother’s immune system does not produce antibodies against Rh-positive blood cells.
Choice D rationale
Rh(D) immune globulin is typically administered intramuscularly, not into the abdomen. The preferred sites are the deltoid muscle or the anterolateral aspect of the thigh.

Correct Answer is A
Explanation
Choice A rationale
Placing the retainer clip at the level of the baby’s armpits is the correct position for the clip. This ensures that the harness straps are positioned correctly over the baby’s shoulders, providing optimal protection in the event of a crash.
Choice B rationale
Placing the baby in the car seat at a 90-degree angle is incorrect. Newborns should be placed in a rear-facing car seat at an angle of approximately 45 degrees to ensure their airway remains open and to provide proper support for their head and neck.
Choice C rationale
Turning the car seat to face forward when the baby weighs 15 pounds is not recommended. Babies should remain in a rear-facing car seat until they reach the maximum weight or height limit specified by the car seat manufacturer, typically around 2 years of age.
Choice D rationale
Placing a thick, soft pad behind the baby’s back is not recommended. Additional padding can interfere with the proper fit of the harness and reduce the effectiveness of the car seat in protecting the baby during a crash.
Correct Answer is D
Explanation
Choice A rationale
Serum bilirubin is not the priority test for hyperemesis gravidarum. It is more relevant for assessing liver function and jaundice.
Choice B rationale
Liver enzymes may be elevated in hyperemesis gravidarum, but they are not the priority test. The primary concern is dehydration and electrolyte imbalance.
Choice C rationale
A CBC can provide information on the client’s overall health, but it is not the priority test for hyperemesis gravidarum. The focus should be on assessing hydration status.
Choice D rationale
Urinalysis for ketones is the priority test because it helps assess the severity of dehydration and malnutrition. The presence of ketones indicates that the body is breaking down fat for energy, which is a sign of inadequate caloric intake.
