Question 1 of 5
A client receives a prescription for a secondary infusion of IV erythromycin 1 gram in 200 mL dextrose 5% in water (D5W) to be infused in 90 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 133
Rationale: Volume = 200 mL, Time = 90 minutes = 1.5 hours. Infusion rate = 200 mL / 1.5 hours = 133.33 mL/hr, rounded to 133 mL/hr.
Question 2 of 5
A client with a cold is taking the antitussive medication benzonatate. Which assessment information indicates to the nurse that the medication is effective?
Correct Answer: B
Rationale: Benzonatate suppresses cough, and sleeping through the night indicates effective cough control. Denying coughing spells is less specific, expectoration relates to expectorants, and nasal discharge is unrelated to antitussive effects.
Question 3 of 5
Before administering a laxative to a bedfast client, it is most important for the nurse to perform which assessment?
Correct Answer: D
Rationale: Assessing bowel movement frequency and consistency is critical to determine the need for a laxative and monitor its effectiveness. Strength, skin integrity, and urge recognition are less directly related to laxative administration.
Question 4 of 5
During a home visit, the nurse assesses a client with Alzheimer's disease who recently started a new prescription for rivastigmine. The caregiver reports that the client seems to be thinking more clearly but is not sleeping well at night. Which action should the nurse take?
Correct Answer: B
Rationale: Insomnia is a common, often temporary side effect of rivastigmine. Explaining this reassures the caregiver. Rivastigmine is for cognition, not sleep, and withholding or increasing the dose is inappropriate without provider guidance.
Question 5 of 5
Levothyroxine sodium is prescribed for a client with hypothyroidism. The nurse should instruct the client to report which symptom because it indicates that the client is taking too much levothyroxine sodium?
Correct Answer: C
Rationale: Restlessness indicates hyperthyroidism, suggesting excessive levothyroxine. Constipation, decreased appetite, and cold intolerance are hypothyroidism symptoms, not overdose.
