NURSING MSN 571 KEY CONCEPTS AND
CLINICAL APPLICATIONS GUIDE 2026
◉ A patient is found to have a genetic deficiency in the biomarker
CYP2C19. The provider recognizes that prescribing clopidogrel will
increase the patient's risk for developing what serious conditions?
Answer: Myocardial infarction, Stroke
◉ A provider speaking to a class or a group of pregnant patients
correctly teaches that the highest risk of teratogen-induced gross
malformations exists during which time period Answer: During the
first trimester
◉ A pregnant patient asks her provider about the safe use of
medications during the third trimester. What will the provider tell
her about drugs taken at this stage? Answer: "They may need to be
given in higher doses if they undergo renal clearance."
◉ A woman who breastfeeds her infant must take a prescription
medication for 2 weeks. The medication is safe, but the patient
wants to make sure her baby receives as little of the drug as
possible. What instructions will the prescriber give the patient to
best address her concerns? Answer: "Take the medication
immediately after breastfeeding your baby."
,◉ Which type of medication prescribed to a pregnant patient is
more likely to have effects on her fetus? Answer: Lipid-soluble drugs
◉ A pregnant woman asks why more is not known about the
teratogenic effects of maternal medication ingestion during
pregnancy. Which response will the provider offer to address the
patient's concern? Answer: "Clinical trials to determine teratogenic
effects would put the fetus at risk."
◉ An infant developed a pruritic rash following exposure to an
allergen. The infant's parents ask the provider about using a topical
antihistamine. What information should the provider use to address
the parents' question? Answer: Applying an antihistamine to the
skin can cause toxicity in this age group.

minimize risk to the infant? Answer: Prescribe a dose that is
relatively lower than an adult dose when adjusted for body surface
area
◉ A pediatric provider is teaching nursing students to calculate
medication doses for children using a formula based on body surface
area. Which statement by a nursing student indicates understanding
of the teaching? Answer: "This formula helps approximate the first
dose; other doses should be based on clinical observations."
◉ A child attending daycare is prescribed 750 mg of an antibiotic for
10 days. The drug may be dosed in several ways and is available in
two concentrations. Which dosing regimen will the provider
consider to best assure drug adherence? Answer: 375 mg of a 500
