Question 1 of 5
A nurse is preparing to administer amikacin 5 mg/kg IM to a client who weighs 110 lb. Available is amikacin injection 250 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if applicable. Do not use a trailing zero.)
Correct Answer: A
Rationale: 110 lb = 50 kg; 5 mg/kg = 250 mg; 250 mg / 250 mg/mL = 1 mL, rounded to 1 mL.
Question 2 of 5
A nurse is caring for a client who is experiencing an acute asthma attack. The nurse should expect to administer which of the following medications?
Correct Answer: A
Rationale: Levalbuterol, a short-acting bronchodilator, provides rapid relief in acute asthma attacks. Cromolyn and budesonide are for prevention, and ipratropium is less commonly the first choice.
Question 3 of 5
A nurse is preparing to administer digoxin to a client. For which of the following findings should the nurse withhold the medication?
Correct Answer: A
Rationale: An apical pulse of 54/min is below the adult threshold of 60 bpm, indicating a risk of bradycardia with digoxin, which slows heart rate. Other findings (normal respiratory rate, hypertension, mild fever) do not warrant withholding the drug.
Question 4 of 5
A nurse is planning to administer medications to a client who has trigeminal neuralgia. Which of the following medications should the nurse plan to administer to manage the client's pain?
Correct Answer: D
Rationale: Carbamazepine, an anticonvulsant, is commonly used to reduce nerve pain in trigeminal neuralgia. Fluoxetine (antidepressant), methylphenidate (stimulant), and lorazepam (anxiolytic) are not indicated for this condition.
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: C
Rationale: Amitriptyline, a tricyclic antidepressant, typically takes several weeks to achieve its full therapeutic effect. Changing the medication or dose after only 6 days is premature, and it doesn't require an empty stomach for efficacy.
