Question 1 of 5
A child has rickets and is being treated at the clinic. In addition to taking vitamin D as prescribed, what is the best information the nurse can provide?
Correct Answer: C
Rationale: Rickets, from vitamin D deficiency, improves with sunlight-20 minutes boosts D synthesis, per physiology-plus supplements. Dairy aids calcium, not avoided. Brand vs. generic is irrelevant-efficacy equals. Empty stomach isn't needed-fat aids absorption. Sunlight complements, per treatment.
Question 2 of 5
A 17-year-old man is brought to the emergency department with severe right lower quadrant pain that he first felt around his umbilicus. His white blood cell count is 12,000/μL of blood. He is taken to the operating room for emergent laparoscopic appendectomy. About an hour into the surgery, his body temperature spikes and CO2 production rises uncontrollably. What is the next step in the treatment of this patient?
Correct Answer: C
Rationale: Fever and CO2 rise during surgery suggest malignant hyperthermia (MH). Dantrolene , a ryanodine receptor antagonist, halts MH by blocking calcium release. Acetaminophen reduces fever but not MH. Bromocriptine treats neuroleptic syndrome. Diazepam and Naproxen (E) are irrelevant. Dantrolene's specificity saves lives in this surgical emergency.
Question 3 of 5
A 21-year-old male college student presents to the emergency department with hives over his chest and arms. The history and physical exam reveals that he used a new laundry detergent and he was having an allergic reaction. The physician wants to prescribe an antihistamine that will not sedate the patient because he has to study for a test. What is the most appropriate treatment?
Correct Answer: D
Rationale: Allergic hives from detergent need a non-sedating antihistamine. Fexofenadine -blocks H1 receptors without drowsiness, ideal for studying. Chlorpheniramine , dimenhydrinate , and diphenhydramine sedate. Ipratropium (E) is irrelevant. Fexofenadine ensures efficacy and alertness.
Question 4 of 5
The nurse is compiling a drug history for a patient. Which question from the nurse will obtain the most information from the patient?
Correct Answer: C
Rationale: A comprehensive drug history includes information about the patient's current and past medication use, including over-the-counter drugs, herbal supplements, and non-pharmacological pain relief methods. Asking, 'When you have pain, what do you do to relieve it?' provides insight into the patient's self-management strategies and helps identify potential drug interactions or misuse. While questions about sleeping pills, family history, and childhood diseases are relevant, they do not provide as much information about the patient's current medication practices. Therefore, focusing on pain relief methods is the most effective way to gather a detailed drug history.
Question 5 of 5
A patient has had recent mechanical heart valve surgery and is receiving anticoagulant therapy. While monitoring the patient™s laboratory work, the nurse interprets that the patient™s international normalized ratio (INR) level of 3 indicates that:
Correct Answer: B
Rationale: An international normalized ratio (INR) level of 3 indicates that the patient's warfarin dose is within the therapeutic range for anticoagulation. In patients with mechanical heart valves, the target INR range is usually higher (around 2.5 to 3.5) to prevent thrombus formation on the prosthetic valve. An INR of 3 demonstrates that the anticoagulant effect of warfarin is at an appropriate level to reduce the risk of blood clots while minimizing the risk of bleeding complications. If the INR level was subtherapeutic (below the target range), it would indicate that the patient is not receiving enough warfarin to achieve the desired anticoagulant effect.
