A nurse inadvertently administers 160 mg of valsartan PO to a client who was scheduled to receive 80 mg.

Which of the following actions is the priority for the nurse to take?

The correct answer is choice C. Wear loose-fitting underwear. This is because tight-fitting underwear can trap moisture and create a favorable environment for bacterial growth, which can increase the risk of urinary tract infections (UTIs) . Loose-fitting underwear can allow air circulation and prevent moisture accumulation .

Choice A is wrong because drinking four 240 mL (8 oz) glasses of water each day is not enough to prevent UTIs. The recommended amount of water intake for adults is about 2 to 3 liters per day . Drinking enough water can help flush out bacteria from the urinary tract and prevent them from adhering to the bladder wall .

Choice B is wrong because voiding every 5 to 6 hours during the day is too infrequent and can increase the risk of UTIs. The nurse should advise the client to void every 2 to 3 hours during the day . This can help prevent urinary stasis and bacterial multiplication in the bladder .

Choice D is wrong because taking a bubble bath after intercourse can increase the risk of UTIs. The nurse should instruct the client to avoid bubble baths, vaginal douches, or sprays, as they can irritate the urethra and introduce bacteria into the urinary tract . The nurse should also advise the client to empty the bladder before and after sexual intercourse, as this can help remove bacteria that may have entered the urethra during sexual activity

The correct answer is choice D, spotting.

Placenta previa is a condition where the placenta implants in the lower part of the uterus, partly or completely covering the cervical opening.

This can cause painless, bright red vaginal bleeding, usually in the third trimester.

Spotting is a sign of placenta previa and should be reported to the provider immediately.

Choice A is wrong because nausea is not a specific finding of placenta previa.

Nausea can occur in normal pregnancy or in other conditions such as hyperemesis gravidarum or preeclampsia.

Choice B is wrong because polyhydramnios is not a finding of placenta previa.

Polyhydramnios is a condition where there is too much amniotic fluid in the uterus, which can cause complications such as preterm labor, cord prolapse, or fetal malformations.

Choice C is wrong because uterine tenderness is not a finding of placenta previa.

Uterine tenderness is a sign of abruptio placentae, which is a condition where the placenta separates from the uterine wall before delivery.

This can cause severe abdominal pain, dark red vaginal bleeding, and fetal distress.
