Question 1 of 5
The healthcare provider prescribes the antibiotic tetracycline HCl for an adult client that arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?
Correct Answer: A
Rationale: Tetracycline causes photosensitivity, increasing sunburn risk, so sun protection (
A) is essential (matches 55-Q9/22). Orange juice (
B) contains calcium, impairing absorption. Weekly drug level checks (
C) are not required. Milk/antacids (
D) reduce absorption by chelating tetracycline.
Question 2 of 5
The nurse prepares to administer a scheduled dose of labetalol by mouth to a client with hypertension. The client's vital signs are temperature 99°F (37.22°C), heart rate 48 beats/minute, respirations 16 breaths/minute, and blood pressure (B/P) 150/90 mm Hg. Which action should the nurse take?
Correct Answer: D
Rationale: Labetalol, a beta-blocker, can worsen bradycardia (48 bpm). Withholding the dose and notifying the provider (
D) is safest (matches 55-Q41). Administering (
B) risks exacerbating bradycardia. Orthostatic hypotension (
A) and telemetry (
C) are secondary.
Question 3 of 5
While assessing a client who takes acetaminophen for chronic pain, the nurse observes that the client's skin looks yellow in color. Which action should the nurse take in response to this finding?
Correct Answer: C
Rationale: Yellow skin (jaundice) suggests liver damage, a serious acetaminophen side effect (
C) (matches 55-Q47). Reporting to the provider is critical. Glucose (
A) and oxygen saturation (
D) are unrelated. Reducing dosage (
B) without consultation is unsafe.
Question 4 of 5
The nurse receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter Calculation(ans only)al value only.)
Correct Answer: 200
Rationale: Infusion rate: 200 mL / 1 hr = 200 mL/hr (matches 55-Q55). The pump should deliver 200 mL/hr for correct ciprofloxacin administration.
Question 5 of 5
An older adult with iron deficiency anemia is being discharged with a prescription for ferrous sulfate enteric-coated tablets. To promote best absorption of the medication, which information should the nurse include in the discharge instructions?
Correct Answer: A
Rationale: Ferrous sulfate is best absorbed on an empty stomach, 2 hours after meals (
A) (matches 55-Q13). Bedtime dosing (
B) isn’t specific. Multivitamins (
C) may reduce absorption. Crushing enteric-coated tablets (
D) disrupts their coating.
