Question 1 of 5
An allergic reaction is classified as what type of pharmacological effect?
Correct Answer: C
Rationale: An allergic reaction is considered an adverse effect, as it is unintended and requires treatment. A side effect is also undesired but is somewhat expected, and a side effect does not require intervention.
Question 2 of 5
The LPN is caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?
Correct Answer: D
Rationale: Grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to breakdown the drug, which leads to excessive amounts of the drug in the body.

Question 5 of 5
The nurse notes from the child's MAR illustrated that the child is to receive the first dose of a newly prescribed medication at 0800 hours. The drug reference book recommends an initial pediatric dose of lamotrigine of 0.6 mg/kg/day in two divided doses for the first 2 weeks. Which action by the nurse is most appropriate?
Correct Answer: B
Rationale: A: Although the medication is written on the MAR, an error still exists in the dose, and the medication should not be administered. B: The nurse should notify the HCP. The child weighs 30 kg; the recommended initial daily dose of lamotrigine (Lamictal) for this child would be 18 mg (0.6 x 30 = 18 mg). If given 18 mg bid, the child would receive a daily dose of 36 mg, twice the recommended initial pediatric dose. C: The child has a new-onset seizure disorder; it is unlikely that the child was taking this medication prior to hospitalization. D: Consulting the pharmacist is unnecessary; the nurse still needs to seek clarification from the HCP.
