Which of the following statements about Group B Streptococcus (GBS) in pregnancy is true?

A.

GBS can only be transmitted to the baby during cesarean delivery.

B.

GBS is a common bacterium found in the vaginal flora of women and is harmless in all cases.

C.

Screening for GBS is typically performed at the first prenatal visit.

D.

Intravenous antibiotics during labor are recommended for GBS-positive mothers to prevent neonatal infection.

Answer and Explanation

The Correct Answer is D

Choice A rationale

GBS can be transmitted to the baby during both vaginal and cesarean deliveries if the mother is colonized with the bacteria. It is not limited to cesarean sections, hence why appropriate screening and treatment are essential.

 

Choice B rationale

GBS, although often harmless in the general population, can cause severe infections in newborns. This bacterium can be a source of severe neonatal infections like sepsis, pneumonia, and meningitis, necessitating preventive measures during pregnancy and delivery.

 

Choice C rationale

Screening for GBS is typically performed between 35 and 37 weeks of gestation, not at the first prenatal visit. This timing ensures accurate detection of the bacteria closer to the time of delivery.

 

Choice D rationale

Intravenous antibiotics during labor are recommended for mothers who test positive for GBS to prevent transmission to the baby. This intervention significantly reduces the risk of neonatal GBS infection.

Explanation

Choice A rationale

Postpartum blues typically resolve within the first two weeks postpartum and involve mild symptoms like mood swings and irritability. In contrast, postpartum depression can persist

longer and requires treatment.

Choice B rationale

Symptoms of postpartum blues usually disappear without medical intervention, whereas postpartum depression often needs professional treatment to manage the more severe and

persistent symptoms.

Choice C rationale

Postpartum depression can impair a mother's ability to care for herself and her baby safely, requiring intervention to prevent harm. Postpartum blues do not typically cause such severe

functional impairment.

Choice D rationale

Postpartum depression may require antidepressants for treatment due to its severity. Postpartum blues generally do not necessitate such interventions and are managed through

support and reassurance.

Choice E rationale

Postpartum depression can occur at any time within the first 12 months after delivery, while postpartum blues are usually confined to the initial two weeks postpartum.

Correct Answer is A

Explanation

Choice A rationale

Methylergonovine (Methergine) is contraindicated in clients with hypertension because it can cause severe hypertension by increasing vascular resistance, leading to potential complications such as stroke.

Choice B rationale

Oxytocin (Pitocin) is used to induce labor and control postpartum hemorrhage and does not significantly increase blood pressure, making it safe for use in hypertensive patients.

Choice C rationale

Carboprost (Hemabate) is used to control severe postpartum hemorrhage and does not have significant effects on blood pressure. It is generally safe for hypertensive patients.

Choice D rationale

Misoprostol (Cytotec) is used for postpartum hemorrhage management and does not significantly affect blood pressure, making it safe for hypertensive patients.
