A nurse is planning to obtain a blood specimen from a newborn via a heel stick.
Which of the following actions should the nurse take?
Cool the newborn's heel prior to the procedure.
Puncture the center of the newborn's heel.
Cleanse the puncture site with alcohol gauze prior to the procedure.
Administer vitamin K 30 minutes prior to each blood draw.
The Correct Answer is C
Choice A rationale
Cooling the newborn’s heel would constrict blood vessels and make it more difficult to obtain a blood sample. Warming the heel is the preferred method to increase blood flow.
Choice B rationale
Puncturing the center of the newborn’s heel is not recommended as it could cause more pain and potential injury to the bone. The puncture should be done on the outer edges of the heel.
Choice C rationale
Cleansing the puncture site with alcohol gauze is essential to reduce the risk of infection and ensure that the sample is not contaminated.
Choice D rationale
Administering vitamin K before each blood draw is unnecessary. Vitamin K is typically given as a one-time dose to prevent bleeding issues, not related to blood draw procedures.

Correct Answer is A
Explanation
Choice A rationale
Manifestations of shock might not appear until a client loses 20% of their blood volume. This is because the body compensates for blood loss by increasing heart rate and
vasoconstriction, maintaining blood pressure until a significant amount of blood is lost.
Choice B rationale
Hemorrhagic shock will cause a decrease, not an increase, in a client's serum pH due to the accumulation of lactic acid from anaerobic metabolism, leading to metabolic acidosis.
Choice C rationale
The most accurate indication of organ perfusion is a client's urine output. Adequate urine output reflects sufficient renal blood flow and overall perfusion, making it a reliable indicator
of organ perfusion.
Choice D rationale
An infusion of 1 mL of lactated Ringers for each 1 mL of blood loss is not accurate. The typical fluid replacement ratio is 3:, meaning 3 mL of crystalloid solution (like lactated Ringers) is given for each 1 mL of blood loss to account for fluid distribution in the body.
Correct Answer is B
Explanation
Choice A rationale
Cesarean birth is not necessarily required for GBS-positive clients as long as IV antibiotic prophylaxis is administered during labor to prevent transmission to the newborn.
Choice B rationale
IV antibiotic prophylaxis, typically with penicillin or ampicillin, is given to GBS-positive clients during labor to prevent neonatal GBS infection.
Choice C rationale
Obtaining a vaginal culture at 39 weeks of gestation is not necessary if the client was already screened and found positive for GBS at 36 weeks.
Choice D rationale
Metronidazole is used to treat bacterial vaginosis or trichomoniasis, not GBS infection; thus, it is not appropriate for this scenario. .
