Question 1 of 5
A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 4 hr as needed. The amount available is diphenhydramine elixir 12.5 mg/5 mL. How many mL 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: Calculation: 25 mg / (12.5 mg/5 mL) = 25 * 5 / 12.5 = 10 mL. The nurse should administer 10 mL per dose.

Question 3 of 5
Patient teaching regarding expectorants should instruct the patient to perform which action?
Correct Answer: A
Rationale: Expectorants like guaifenesin thin mucus, making it easier to cough up. Increasing fluid intake helps keep mucus less viscous, aiding expectoration. Restricting fluids thickens mucus, and constipation is not a common issue with expectorants.
Question 4 of 5
A client with diabetes mellitus is being admitted to the hospital for surgery. The client has been taking Glucocorticoids (Prednisone) long-term for uncontrolled COPD. Which of the following must the nurse consider when she is obtaining a health history?
Correct Answer: A,C,D
Rationale: Long-term glucocorticoids suppress adrenal function, requiring gradual tapering to avoid insufficiency. They increase infection risk by suppressing immunity and can elevate blood glucose by causing insulin resistance. Low blood pressure and increased pain are not typical concerns.
Question 5 of 5
A nurse is teaching a client who has a new prescription for codeine. Which of the following instructions should the nurse include in the teaching?
Correct Answer: B
Rationale: Codeine, an opioid, can cause dizziness and orthostatic hypotension. Changing positions slowly reduces fall risk. Diarrhea is not typical, alcohol should be avoided entirely, and taking with food may reduce nausea.
