A nurse is reinforcing teaching with a client who is at 38 weeks of gestation and has a positive group B streptococcus B-hemolytic screening.
Which of the following medications should the nurse discuss as the prophylaxis treatment during labor for this client?
Penicillin.
Cefazolin.
Erythromycin.
Vancomycin.
The Correct Answer is A
Choice A rationale
Penicillin is the recommended prophylactic treatment for a client at 38 weeks of gestation with a positive group B streptococcus B-hemolytic screening. It is highly effective in preventing the transmission of group B strep from mother to baby during labor and delivery. Administering Penicillin reduces the risk of neonatal sepsis, pneumonia, and meningitis caused by group B strep.
Choice B rationale
Cefazolin is an alternative antibiotic for clients allergic to penicillin. It is less preferred compared to penicillin due to its broader spectrum of activity and potential for resistance. Cefazolin can be used if the client has a non-severe penicillin allergy.
Choice C rationale
Erythromycin is not recommended for group B strep prophylaxis during labor due to its lower efficacy compared to penicillin and cefazolin. It is less effective in preventing neonatal group B strep infections and is used less frequently.
Choice D rationale
Vancomycin is used for clients with a severe penicillin allergy or for those with resistant strains of group B strep. It is a last-resort antibiotic due to its potent effect and potential side effects. It is only used when absolutely necessary.

Correct Answer is D
Explanation
Choice A rationale
An apical pulse of 66/min is within the normal range and not indicative of postpartum hemorrhage, which would typically cause an elevated heart rate due to blood loss.
Choice B rationale
A temperature of 38.3°C (101°F) could indicate infection or inflammation but is not a direct sign of postpartum hemorrhage, which primarily involves significant blood loss.
Choice C rationale
Blood pressure of 156/80 mm Hg is elevated but not directly indicative of postpartum hemorrhage, which would typically result in a drop in blood pressure due to loss of blood volume.
Choice D rationale
A respiratory rate of 32/min is significantly elevated and can be a compensatory response to hypovolemia from postpartum hemorrhage. This response occurs as the body tries to increase oxygen delivery due to blood loss.
Correct Answer is D
Explanation
Choice A rationale
Instructing the client to apply anesthetic spray to the site three to four times a day is incorrect. While anesthetic sprays can help with pain relief, it's more important to manage swelling and discomfort with a combination of methods, including ice packs and perineal care.
Choice B rationale
Encouraging the client to change perineal pads at least three times a day is insufficient. Pads should be changed more frequently to maintain hygiene and prevent infection.
Choice C rationale
Assisting the client to fill the squeeze bottle with cold water to perform perineal care is incorrect. While perineal care is important, cold water is not typically recommended as it may not provide comfort and might even cause discomfort.
Choice D rationale
Alternating warm and ice packs to the site every 2 hours for the first 24 hours postpartum is correct. This method helps manage pain and swelling effectively, promoting healing and comfort for the client.
