A charge nurse is providing teaching to a newly licensed nurse who is caring for a client who has postpartum hemorrhagic shock.
Which of the following statements should the charge nurse make?
Manifestations of shock might not appear until a client loses 20% of their blood volume.
Hemorrhagic shock will cause an increase in a client's serum pH.
The most accurate indication of organ perfusion is a client's urine output.
An infusion of 1 mL of lactated Ringers is given for each 1 mL of blood loss.
The Correct Answer is A
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 A
Explanation
Choice A rationale
Rear-facing car seats are safer for infants and toddlers because they provide better support for their head, neck, and spine in the event of a collision. The American Academy of Pediatrics recommends keeping children in rear-facing seats until they are at least 2 years old or until they reach the highest weight or height allowed by the manufacturer.
Choice B rationale
A four-point harness is not sufficient for securing a baby in a car seat. A five-point harness, which includes two shoulder straps, two hip straps, and one crotch strap, provides more secure and effective restraint for infants.
Choice C rationale
The shoulder harness should be positioned in the slots at or below the baby's shoulders, not above, to ensure proper fit and restraint. Placing the harness above the shoulders can result in improper restraint and increased risk of injury in an accident.
Choice D rationale
The correct angle for a rear-facing car seat is typically 45 degrees, not 30 degrees. A 45-degree angle ensures the baby's airway remains open, preventing the head from falling forward and potentially causing breathing difficulties.
Correct Answer is C
Explanation
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.
