Extract:
Question 1 of 5
A nurse is reinforcing teaching with a client who is to start therapy with insulin lispro and insulin glargine. Which of the following should the nurse include in the teaching?
Correct Answer: D
Rationale: Insulin lispro, a rapid-acting insulin, is taken right before meals to control postprandial glucose spikes. Lispro and glargine shouldn't be mixed, glargine is once daily, and shaking vials risks inaccurate dosing.
Question 2 of 5
A nurse is preparing to administer a levothyroxine 50 mcg tablet PO to a client who is receiving an enteral feeding through an NG tube. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Dissolving levothyroxine in 30 mL of water ensures it's suitable for NG tube administration and prevents clogging. Supine positioning risks aspiration, mixing with formula can reduce efficacy, and 5 mL is insufficient to clear the tube (15-30 mL is standard).
Question 3 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.
Question 4 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 5 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.
