Question 1 of 5
A nurse working in an urgent care clinic is collecting data from a client who takes montelukast. Which of the following is an expected therapeutic effect of this medication?
Correct Answer: D
Rationale: Montelukast, a leukotriene inhibitor, reduces bronchial inflammation in asthma, its primary therapeutic effect. It doesn't affect vasodilation, WBC count, or gastric acid.
Question 2 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: A
Rationale: 66 lb = 30 kg; 0.24 mg/kg/week = 7.2 mg/week; 7.2 mg / 6 doses = 1.2 mg/dose, rounded to 1.2 mg.
Question 3 of 5
A nurse in an acute care facility is collecting data from a client who has received the meningococcal conjugate vaccine. The nurse should monitor the client for which of the following findings as an adverse effect of the vaccine?
Correct Answer: C
Rationale: Headache is a common adverse effect of the meningococcal conjugate vaccine. Blurred vision, tinnitus, and dry mouth are not typically associated with this vaccine.
Question 4 of 5
A nurse is reinforcing discharge teaching with a client who has a new prescription for rifampin. Which of the following information should the nurse include?
Correct Answer: C
Rationale: Rifampin is best absorbed on an empty stomach, 1 hr before or 2 hr after meals. It may cause orange urine (not blue/green), doesn't typically cause insomnia, and hair growth isn't a side effect.
Question 5 of 5
A nurse is reinforcing teaching with a newly licensed nurse about age-related changes that affect medication administration for older adult clients. Which of the following information should the nurse include?
Correct Answer: A
Rationale: Renal excretion slows with age, increasing drug levels and side effect risks in older adults. Hepatic metabolism slows (not speeds), brain sensitivity varies, and gastric emptying decreases.
