A client in the third stage of labor has experienced placental separation and expulsion.
Why is it necessary for a nurse to massage the woman's uterus briefly until it is firm?.

The correct answer is choice D.

Choice A rationale:

While a urinary tract infection can cause frequent urination, it’s usually accompanied by other symptoms such as pain or burning during urination.

Choice B rationale:

Trauma to pelvic muscles can cause urinary incontinence, not necessarily increased frequency.

Choice C rationale:

Urinary overflow is a condition where the bladder is always full and can lead to frequent leakage of urine.

Choice D rationale:

Postpartum diuresis is the body’s way of getting rid of excess fluid accumulated during pregnancy, leading to increased urine production and frequency.

The correct answer is choice B.

Choice A rationale:

Vitamin K is given to newborns to prevent bleeding disorders, not eye conditions.

Choice B rationale:

Erythromycin ophthalmic ointment is commonly used for prophylaxis of neonatal conjunctivitis (pink eye) caused by Neisseria gonorrhoeae and Chlamydia trachomatis.

Choice C rationale:

Gentamicin ophthalmic ointment can be used to treat bacterial infections of the eye, but it is not typically used for prophylaxis of neonatal eye conditions.

Choice D rationale:

Silver nitrate solution was once used for prophylaxis of neonatal eye conditions, but it is no longer commonly used due to the risk of chemical conjunctivitis.
