  1. A patient taking phenytoin (Dilantin) for seizures should be taught to report which finding to the provider?

    Answer: Gingival hyperplasia (gum overgrowth)

    Gingival hyperplasia is a well-known side effect of phenytoin that requires regular dental care and should be reported to the provider.

  2. A patient is prescribed albuterol (ProAir) and fluticasone (Flovent) inhalers. In what order should they be administered?

    Answer: Albuterol first, then fluticasone 5 minutes later

    Albuterol (bronchodilator) is given first to open the airways, allowing the inhaled corticosteroid (fluticasone) to reach deeper into the lungs.

  3. A patient is ordered morphine 2-4 mg IV PRN for pain rated 7/10. The last dose was 3 hours ago. Which action is appropriate?

    Answer: Administer 4 mg IV since the pain is severe

    With a pain rating of 7/10 and a PRN order for 2-4 mg, administering the higher end of the range is appropriate for severe pain.

  4. Which laboratory value indicates that a patient's INR therapeutic goal is being met for atrial fibrillation management with warfarin?

    Answer: INR 2.5

    The therapeutic INR range for atrial fibrillation is 2.0–3.0, and an INR of 2.5 falls within this therapeutic window.

  5. A patient prescribed lithium for bipolar disorder should be taught to maintain adequate intake of which substance to prevent toxicity?

    Answer: Sodium

    Sodium depletion causes the kidneys to reabsorb lithium instead of sodium, leading to lithium toxicity; adequate sodium intake is essential.

  6. A patient receiving chemotherapy is prescribed ondansetron. What is the primary purpose of this medication?

    Answer: To prevent chemotherapy-induced nausea and vomiting

    Ondansetron is a 5-HT3 receptor antagonist used as an antiemetic to prevent nausea and vomiting associated with chemotherapy.

  7. Which sign or symptom is most indicative of acetaminophen overdose in the later stages?

    Answer: Jaundice and right upper quadrant pain

    Acetaminophen overdose causes hepatotoxicity, manifesting as jaundice and right upper quadrant pain due to liver damage in later stages.
