A primigravida with a history of no prenatal care delivers a normal neonate by sterile vaginal delivery with no complications. The practical nurse (PN) enters the room with an injection of Rho immune globulin and explains the rationale for the injection.
Which situation warrants this injection?
The mother is Rh negative and the baby is Rh positive.
The mother is Rh positive and the baby is Rh negative.
The mother is Rh negative and the baby is Rh negative.
The mother is Rh positive and the father is Rh negative.
The Correct Answer is A
Choice A rationale
Rho immune globulin (RhoGAM) is administered to Rh-negative mothers who have given birth to an Rh-positive baby. This injection prevents the mother's immune system from developing antibodies against Rh-positive red blood cells, which could otherwise harm future Rh-positive fetuses in subsequent pregnancies through hemolytic disease of the newborn.
Choice B rationale
If the mother is Rh positive and the baby is Rh negative, there is no risk of Rh incompatibility. The Rh-positive mother's immune system will not produce antibodies against the Rh-negative fetal red blood cells, as she already possesses the Rh antigen. Therefore, Rho immune globulin is not indicated in this scenario, as there is no sensitization risk.
Choice C rationale
When both the mother and the baby are Rh negative, there is no Rh incompatibility. Since neither the mother nor the baby has the Rh antigen, the mother's immune system will not be stimulated to produce anti-Rh antibodies. Consequently, Rho immune globulin administration is unnecessary in this situation, as no immune response will be triggered.
Choice D rationale
The Rh status of the father is relevant in determining the potential for Rh incompatibility, but it does not directly dictate the need for Rho immune globulin. The critical factor is the Rh status of the mother and the baby. If the mother is Rh positive, regardless of the father's Rh status, she will not produce Rh antibodies, and RhoGAM is not indicated.

Correct Answer is B
Explanation
Choice A rationale
A visit summary documenting the report of abuse may be legally required for documentation but does not directly provide the client with immediate safety resources. The priority is to empower the client with actionable steps to ensure her safety and well-being in an abusive situation.
Choice B rationale
Contact information for a women's shelter provides a crucial immediate resource for safety and support. These shelters offer a safe haven, counseling, and assistance with legal and social services, empowering the client to escape the abusive environment and access necessary resources for herself and potentially her children.
Choice C rationale
Paperwork needed to file a restraining order is a legal step that the client may choose to pursue later. However, in an immediate confiding situation, providing a direct safety resource like shelter information is more paramount, as filing a restraining order requires time and legal processes that may not offer immediate protection.
Choice D rationale
A safety plan to keep in a purse at all times is a valuable tool for future use but does not address the immediate need for a safe place or resources. While important for long-term safety, the initial intervention should focus on providing immediate pathways to escape the abusive situation.
Correct Answer is C
Explanation
Choice A rationale
Assessing elimination hygiene habits is important for preventing recurrent UTIs, but it does not directly address the immediate goal of minimizing complications of vesicoureteral reflux (VUR) in an acute febrile UTI. While good hygiene reduces bacterial entry, VUR involves retrograde urine flow.
Choice B rationale
Completing post-void bladder scans helps assess bladder emptying and residual urine, which are risk factors for UTIs. However, in the context of VUR and a febrile UTI, it's a diagnostic tool rather than a primary intervention to actively minimize the reflux itself during the infection.
Choice C rationale
Implementing a frequent voiding schedule minimizes the volume of urine in the bladder and reduces the duration of bladder distention. This decreases the likelihood of vesicoureteral reflux and helps to flush out bacteria, thus minimizing the risk of renal parenchymal damage during a febrile UTI.
Choice D rationale
Encouraging adequate oral fluid intake helps flush bacteria from the urinary tract and prevents dehydration, which is beneficial for overall health and UTI management. However, while important, it does not directly impact the mechanics of vesicoureteral reflux as effectively as frequent bladder emptying.
