A nurse is teaching about safe handling of formula to a client who is postpartum and chooses to bottle feed her newborn. Which of the following statements by the client indicates an understanding of the teaching?

"I will be sure that all of my bottles contain BPA."

"I can keep a can of concentrated formula in the refrigerator for 3 days after I open it."

"I should boil tap water for 2 minutes and cool it before I mix it with the powdered formula."

"I can dilute the ready-to-feed formula with water when my baby wants more than 4 ounces at a feeding."

Answer and Explanation

The Correct Answer is C

A. BPA (bisphenol A) is harmful, and bottles should be BPA-free.

B. Concentrated formula should be used within 24–48 hours after opening if refrigerated, not 3 days.

C. This is the correct answer. Boiling tap water for 1–2 minutes and cooling it before mixing with powdered formula helps eliminate bacteria, ensuring safe consumption for newborns.

D. Diluting ready-to-feed formula is unsafe and can lead to inadequate nutrition for the baby.

Correct Answer is A

Explanation

A. Placental abruption – This is the correct answer because placental abruption occurs when the placenta detaches prematurely from the uterine wall, leading to severe abdominal pain, vaginal bleeding, uterine rigidity, and signs of hypovolemic shock (low blood pressure). The hallmark sign is a painful, rigid abdomen with contractions.

B. Amniotic fluid embolus – This condition presents with sudden respiratory distress, hypotension, and disseminated intravascular coagulation (DIC), but it does not typically cause uterine rigidity or persistent contractions.

C. Placenta previa – Placenta previa typically presents with painless vaginal bleeding rather than severe abdominal pain and a rigid uterus.

D. Uterine rupture – Uterine rupture is usually associated with a history of uterine surgery (e.g., previous cesarean section). It presents with sudden, severe pain followed by cessation of contractions, not persistent contractions.

A. Potassium level B. Thyroid function tests C. Uric acid level D. Liver function tests

Correct Answer is D

Explanation

A. Potassium level – Valproic acid does not significantly affect potassium levels, so this is not a necessary baseline test.

B. Thyroid function tests – Valproic acid is not known to significantly impact thyroid function, making this an unnecessary test.

C. Uric acid level – Uric acid levels are more relevant for conditions like gout, and valproic acid does not typically cause hyperuricemia.

D. Liver function tests – This is the correct answer because valproic acid is metabolized in the liver and can cause hepatotoxicity. Baseline liver function tests (LFTs) should be reviewed before starting the medication to assess liver health.
