A nurse is assisting with a pelvic examination of a client during their first prenatal visit. Which of the following actions should the nurse take?
Ensure the client has a full bladder before the procedure.
Instruct the client to bear down when the speculum is inserted.
Encourage the client to take rapid, shallow breaths during the procedure.
Apply povidone-iodine to the provider's fingers prior to bimanual examination.
The Correct Answer is B
Choice A rationale
Ensuring the client has a full bladder before the procedure is incorrect. A full bladder can cause discomfort during the pelvic examination and may obscure the pelvic organs, making the examination more challenging for the provider.
Choice B rationale
Instructing the client to bear down when the speculum is inserted is correct. Bearing down helps relax the pelvic muscles, making it easier to insert the speculum and perform the examination with minimal discomfort.
Choice C rationale
Encouraging the client to take rapid, shallow breaths during the procedure is incorrect. This can increase anxiety and tension in the pelvic muscles, making the examination more uncomfortable.
Choice D rationale
Applying povidone-iodine to the provider's fingers prior to bimanual examination is incorrect. The standard procedure involves using gloves and lubricant to prevent infection and ensure patient comfort, not povidone-iodine.

Correct Answer is A
Explanation
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 A
Explanation
Choice A rationale
Positioning the newborn's car seat at a 45° angle helps to maintain an open airway and reduces the risk of the baby's head falling forward, which can obstruct breathing.
Choice B rationale
Placing the car seat in a forward-facing position is incorrect for a newborn. Newborns and infants should always be placed in a rear-facing car seat to protect their head, neck, and spine in the event of a crash.
Choice C rationale
Placing a rolled blanket behind the newborn's neck is not recommended as it can alter the position of the head and neck, potentially compromising the airway. Proper positioning is crucial to ensure safety and comfort.
Choice D rationale
The retainer clip should be positioned at the level of the newborn's armpits, not the umbilicus. Proper placement of the retainer clip ensures that the harness is secure and reduces the risk of injury in a collision.
