Question 1 of 5
A nurse is collecting data from a client who received diphenhydramine 1 hr ago after developing an allergic reaction to trimethoprim-sulfamethoxazole. Which of the following statements by the client should indicate to the nurse that the medication is effective?
Correct Answer: A
Rationale: A no-longer-hoarse voice indicates diphenhydramine has reduced throat swelling from the allergic reaction, showing effectiveness. Alertness contradicts its sedative effect, and headache or appetite changes are not primary indicators.
Question 2 of 5
A nurse is collecting data from a client who received levalbuterol 30 min ago. Which of the following findings should the nurse identify as a therapeutic effect of the medication?
Correct Answer: A
Rationale: Levalbuterol, a bronchodilator, reduces wheezing by relaxing airway muscles, its primary therapeutic effect. Increased respiratory rate or heart rate are side effects, and it doesn't treat nausea.
Question 3 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 4 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 5 of 5
A nurse is collecting data from a client who is receiving vancomycin for a Clostridium difficile infection. Which of the following findings is the priority for the nurse to report to the provider?
Correct Answer: D
Rationale: Creatinine 3.1 mg/dL indicates kidney damage, a serious vancomycin side effect requiring immediate reporting. Loose stools, slight WBC elevation, and tachycardia are less urgent.
