A nurse is caring for a client who is postpartum, has a deep-vein thrombosis, and is receiving heparin therapy via subcutaneous injections. Which of the following actions should the nurse take?

Choice A rationale:

Petroleum jelly is a common recommendation to apply during diaper changes for circumcised newborns. It acts as a barrier between the diaper and the healing penis, reducing friction and preventing the diaper from sticking to the sensitive area. This can help promote better healing and prevent discomfort for the newborn.

Choice B rationale:

Pre-moistened towelettes are not typically recommended for application on the penis of a circumcised newborn during diaper changes. These towelettes may contain chemicals or irritants that could potentially irritate the delicate skin of the healing area.

Choice C rationale:

Povidone-iodine is an antiseptic solution often used to disinfect the skin before procedures or surgeries. However, it is not recommended for routine use on the penis of a circumcised newborn during diaper changes as it may be too harsh for the healing skin.

Choice D rationale:

Silver sulfadiazine is a topical antimicrobial agent used for treating burns and certain infections. However, it is not indicated for use on a circumcised newborn's penis during diaper changes. The healing process after circumcision does not usually involve infections that require this type of treatment.

Choice A rationale:

Administering oxytocin to the client via intravenous infusion is not appropriate when the nurse notes an umbilical cord protruding through the cervix. The priority is to relieve pressure on the cord to prevent fetal compromise, and administering oxytocin could worsen the situation.

Choice B rationale:

Applying oxygen at 2 L/min via nasal cannula is not the priority when an umbilical cord prolapse is detected. The focus should be on relieving pressure on the cord and changing the client's position to alleviate the compression.

Choice C rationale:

Preparing for insertion of an intrauterine pressure catheter is not appropriate when there is an umbilical cord prolapse. The immediate concern is the potential compromise of fetal blood flow, and addressing the cord prolapse takes precedence over any other interventions.

Choice D rationale:

Assisting the client into the knee-chest position is the correct action when an umbilical cord prolapse is observed during a vaginal exam. This position helps to alleviate pressure on the cord by moving the presenting part of the fetus off the cord and can prevent further fetal distress until more definitive interventions can be performed.
