Question 1 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 2 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.
Question 3 of 5
The nurse is planning to administer the antiulcer gastrointestinal (GI) agent sucralfate to a client with peptic ulcer disease. Which action should the nurse include in this client's plan of care?
Correct Answer: A
Rationale: Sucralfate forms a protective barrier over ulcers and should be given on an empty stomach (
A), 1 hour before meals or at bedtime (matches 55-Q10). Candida infection (
B) and electrolyte imbalances (
D) are not associated. Once-daily dosing (
C) is incorrect; it’s typically 4 times daily.
Question 4 of 5
A female client who is a vegetarian has a new prescription for warfarin. The client states she eats leafy green vegetables every day. How should the nurse respond?
Correct Answer: C
Rationale: Leafy greens, high in vitamin K, reduce warfarin’s anticoagulant effect (
C) (matches 55-Q46). Informing the provider ensures dose adjustment. Substituting vegetables (
A) is unnecessary. Praising (
B) or claiming enhanced efficacy (
D) ignores the interaction.
Question 5 of 5
Prior to administering the evening dose of carbamazepine, the nurse notes that the client's morning carbamazepine level was 8.4 mg/L (35.6 mcmol/L). Which action should the nurse take?
Correct Answer: B
Rationale: Carbamazepine’s therapeutic range is 4-12 mg/L; 8.4 mg/L (
B) is therapeutic, so administer as prescribed (matches 55-Q23, but 55-Q23 had 84 mg/L, likely a typo). Notifying (
A) or withholding (
D) is unnecessary. Assessing side effects (
C) is routine but not specific.
