A nurse is providing dietary teaching to a client who is at 29 weeks of gestation and has phenylketonuria.
Which of the following food suggestions should the nurse include?
Peanut butter sandwich.
Sliced apples.
Glass of skim milk.
Scrambled egg.
The Correct Answer is B
Choice A rationale
Peanut butter contains high phenylalanine levels, contraindicated in phenylketonuria. This amino acid accumulates in individuals lacking phenylalanine hydroxylase, causing neurotoxicity and developmental delay.
Choice B rationale
Apples are low in phenylalanine, making them a safe option for individuals with phenylketonuria. They provide essential nutrients without contributing to phenylalanine accumulation.
Choice C rationale
Skim milk is rich in phenylalanine due to its high protein content. Consumption in phenylketonuria leads to amino acid buildup and potential neurological harm.
Choice D rationale
Eggs are protein-dense and therefore contain significant phenylalanine levels. This amino acid must be restricted in phenylketonuria to prevent its toxic effects on the brain. .

Correct Answer is A
Explanation
Choice A rationale
Ibuprofen can interact with various over-the-counter medications, including anticoagulants and corticosteroids, which may increase risks of side effects like gastrointestinal bleeding or reduced efficacy, necessitating careful assessment of concurrent drug use.
Choice B rationale
Ibuprofen use is contraindicated in individuals with gastric issues, such as peptic ulcers, as it inhibits prostaglandins, reducing mucosal protection and increasing risks of gastrointestinal perforation and bleeding.
Choice C rationale
Assessing contraception use is irrelevant to ibuprofen administration because ibuprofen lacks teratogenic effects or interference with hormonal contraception and poses no pregnancy-related risks at therapeutic doses.
Choice D rationale
While ibuprofen can elevate blood pressure via prostaglandin inhibition, this is secondary and less clinically significant compared to immediate concerns like drug interactions or gastric side effects.
Correct Answer is A
Explanation
Choice A rationale
Abruptio placentae involves premature placental separation, linked to cocaine use, which increases vasoconstriction and hypertension. Symptoms include pain, vaginal bleeding, and fetal distress due to impaired placental function.
Choice B rationale
Hydatidiform mole causes abnormal trophoblastic growth with no association with cocaine use. Signs include significantly elevated HCG and uterine enlargement unrelated to gestational age.
Choice C rationale
Preterm labor may follow substance use but lacks the hallmark signs of pain and bleeding characteristic of abruptio placentae. Preterm labor focuses on uterine contractions and cervical changes.
Choice D rationale
Placenta previa presents with painless vaginal bleeding and no abdominal pain. Cocaine use does not heighten placenta previa risk directly but may cause other obstetric complications.
