Question 1 of 5
A client is prescribed methotrexate (Rheumatrex) for rheumatoid arthritis. Which teaching point should the nurse emphasize?
Correct Answer: A
Rationale: Methotrexate, a DMARD, treats RA but risks renal toxicity from crystal formation. Drinking plenty of water ensures excretion, reducing this risk, a critical teaching point. Milk doesn't help'absorption is unaffected. Green leafy vegetables increase folate, which methotrexate depletes, but supplementation is controlled. Stopping if better risks flare-ups. Hydration aligns with methotrexate's pharmacokinetics, vital in RA where long-term safety matters, making A the priority to emphasize for renal protection.
Question 2 of 5
What patient history would the nurse recognize as a contraindication for beginning Niacin therapy?
Correct Answer: B
Rationale: Gout is a contraindication for beginning Niacin therapy due to its potential to exacerbate gout symptoms. Niacin can lead to hyperuricemia, which is increased uric acid levels in the blood, and that can trigger a gout attack. Patients with a history of gout should avoid Niacin therapy to prevent worsening of their condition.
Question 3 of 5
The nurse completes medication education for the client receiving antihistamines. The nurse evaluates that learning has occurred when the client makes which statement?
Correct Answer: D
Rationale: First-generation antihistamines cause sedation. 'This medication could make me very sleepy' shows understanding, indicating effective education. Alcohol worsens sedation. Fluids aren't key. OTC doesn't mean safe. D ensures safety awareness, making it the best statement.
Question 4 of 5
How would you teach a patient how to prep an inhaler?
Correct Answer: B
Rationale: Teaching a patient how to prepare an inhaler is an important step in proper medication administration. Shaking the inhaler for about 5 seconds before use helps to ensure that the medication is properly mixed and dispersed. This is especially important for metered-dose inhalers where the medication is dispersed as a fine spray. Priming the inhaler by shaking it helps ensure that the patient receives the correct dose of medication with each use.
Question 5 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.
