Question 1 of 5
A nurse is reinforcing discharge teaching with the family of a client who has a new diagnosis of Parkinson's disease and a prescription for levodopa/carbidopa. Which of the following statements made by the client's family indicates an understanding of the teaching?
Correct Answer: B
Rationale: Eating a lot of protein can interfere with the absorption of levodopa, so this statement is incorrect. Levodopa/carbidopa can cause dyskinesias or involuntary movements, so monitoring for this is essential. Levodopa does not cure Parkinson's disease or prevent its progression; it helps manage symptoms. While levodopa can improve symptoms, the onset of action is not typically rapid, and it may take some time for optimal effect.
Question 2 of 5
A nurse is reviewing the medication list of a client who has a new prescription for tetracycline. The nurse should instruct the client to take which of the following medications 3 hr before or after taking the tetracycline?
Correct Answer: B
Rationale: No specific timing restrictions with tetracycline. Tetracycline absorption is reduced when taken with antacids, so they should be taken 3 hours before or after tetracycline. No specific timing restrictions with tetracycline. No specific timing restrictions with tetracycline.
Question 3 of 5
A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 1.2
Rationale: 1. Convert weight from pounds to kilograms: Child's weight = 66 lb, Conversion factor: 1 kg = 2.2 lb, 66 lb ÷ 2.2 = 30 kg. 2. Calculate the total weekly dose: Prescribed dose = 0.24 mg/kg/week, 30 kg × 0.24 mg/kg = 7.2 mg/week. 3. Determine the daily dose: The dose is given six times per week, 7.2 mg ÷ 6 = 1.2 mg/day. The nurse should administer 1.2 mg of somatropin per dose subcutaneously to the child.
Question 4 of 5
A nurse is monitoring a client who received naloxone to counteract the effects of an opioid overdose. Which of the following findings should indicate to the nurse that the medication is effective?
Correct Answer: C
Rationale: Naloxone administration may lead to an increase in blood pressure, not a decrease. While pain relief might occur, the primary goal of naloxone is to reverse respiratory depression, not to relieve pain. Naloxone is an opioid antagonist that reverses opioid-induced respiratory depression, so an increased respiratory rate indicates its effectiveness. Naloxone does not typically affect body temperature in a significant way.
Question 5 of 5
A nurse is caring for a client who started taking amitriptyline 6 days ago. The client reports that the medication is not helping. Which of the following responses should the nurse make?
Correct Answer: D
Rationale: It is premature to change medications after only 6 days, as antidepressants may take several weeks to show therapeutic effects. Dose adjustments should be done cautiously, and waiting for the full therapeutic effect is important before making changes. Administration instructions do not significantly impact the speed of therapeutic effects. This is the correct answer because amitriptyline is a tricyclic antidepressant that takes 2 to 4 weeks to reach its full effect.
