Correct Answer: C

Rationale: In the scenario where a newborn's mother is positive for hepatitis B surface antigen, the infant should receive both hepatitis B immune globulin and hepatitis B vaccine within 12 hours of birth. This is crucial to provide passive and active immunity against the Hepatitis B virus. Hepatitis B immune globulin provides immediate protection by giving passive immunity, while the vaccine stimulates active immunity in the infant. Administering both within 12 hours of birth is important to prevent vertical transmission of the virus.

Correct Answer: B

Rationale: A respiratory rate of 16/min within the normal range is an essential parameter to monitor when administering magnesium sulfate, as respiratory depression is a potential adverse effect. Diminished deep-tendon reflexes may indicate magnesium toxicity, warranting immediate intervention. A urine output of 50 mL in 4 hours is below the expected amount, suggesting decreased kidney perfusion, which can be exacerbated by magnesium sulfate. A heart rate of 56/min is bradycardic and may indicate magnesium toxicity, requiring assessment and possible discontinuation of the infusion.

Correct Answer: B

Rationale: Offering the client the option to view products of conception after an inevitable abortion can provide closure and support the grieving process. It allows the client to have a visual confirmation of the pregnancy loss, which can aid in emotional healing. Administering oxygen is not a priority in this scenario as there is no indication of respiratory distress. Instructing the client to increase potassium-rich foods is not directly related to managing an inevitable abortion. Bed rest may be recommended, but offering the option to view products of conception is a more appropriate intervention at this time.

Correct Answer: D

Rationale: Placenta previa is a condition where the placenta partially or completely covers the cervix, leading to potential bleeding. When admitting a client with placenta previa, the priority is to assess the fetal well-being. Applying an external fetal monitor helps in continuous monitoring of the fetal heart rate and ensures timely detection of any distress or changes in the fetal status, which is crucial in managing this condition. While monitoring vaginal bleeding is important, identifying fetal well-being takes precedence in this situation.

Correct Answer: A

Rationale: Delegating the task of providing a sitz bath to a client with a fourth-degree laceration and who is 2 days postpartum to the assistive personnel (AP) is appropriate. This task involves assisting the client with personal hygiene and comfort measures that can be safely performed by the AP under the supervision and direction of the nurse. Tasks like observing redness on the breast, monitoring vital signs during admission for gestational hypertension, and changing perineal pads may require a higher level of assessment and nursing judgment, making them more appropriate for the nurse to perform.
