effectively."

Metformin for type 2 diabetes. The patient asks why regular kidney function monitoring is

ineffective. The nurse suspects a genetic variation may be responsible. Which pharmacogenomic

explanation should the nurse provide to the patient?

"Some individuals lack the enzyme CYP2D6, which is needed to convert codeine into its

active form, making it ineffective for pain relief."

---

**Case Study 4**

A nurse is providing education to a patient who has recently been prescribed clopidogrel (Plavix)

after experiencing a stroke. The patient expresses concerns about why genetic testing was

suggested before starting the medication. Which explanation by the nurse is appropriate?

"Certain genetic variations can reduce your ability to metabolize clopidogrel effectively,

decreasing its protective effects against blood clots."

**Case Study 5**

A nurse caring for an elderly patient with hypertension notes that the patient has been prescribed

a beta-blocker. The patient reports feeling dizzy and tired. Which explanation by the nurse is

correct regarding beta-blocker pharmacokinetics in older adults?

"Older adults may have a slower metabolism and clearance of beta-blockers, which can cause

the medication to build up and lead to side effects like dizziness and fatigue."

**Case Study 6**

Parents of a 4-year-old child ask why amoxicillin is prescribed instead of a stronger antibiotic for

an ear infection. Which response by the nurse is correct?

likely to lead to antibiotic resistance than stronger antibiotics."

---

numbness and tingling in their extremities. Which question should the nurse ask when taking the

provider prescribes a course of Nitrofurantoin. The patient asks if this medication is safe for her

baby. What is the nurse’s correct response?

3

, "Nitrofurantoin is generally safe during most stages of pregnancy, but it’s usually avoided

near term due to the risk of hemolytic anemia in newborns with certain enzyme deficiencies."

---

**Case Study 9**

A parent asks the nurse why tetracycline is not recommended for children under 8 years old.

What is the nurse’s correct response?

"Tetracycline can bind to calcium in teeth and bones, causing permanent tooth discoloration

A nurse is caring for a patient who has a history of seizures and is prescribed phenytoin. The
