Question 1 of 5
A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD), reports about having difficulty sleeping at night. Which assessment is most important for the nurse to obtain?
Correct Answer: A
Rationale: Late dosing of dextroamphetamine-amphetamine, a stimulant, can cause insomnia. Assessing dose timing identifies if earlier administration mitigates sleep issues. Bedtime routines, anxiety, or caffeine are secondary.
Question 2 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 μg/dL (6 to 47 μmol/L)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium in hyperkalemia. A potassium level of 3.8 mEq/L (normal) indicates effectiveness. Ammonia, glucose, and hemoglobin are unaffected.
Question 3 of 5
The nurse is planning the home care of a client who is receiving a mydriatic medication. Which environment is best for this client?
Correct Answer: A
Rationale: Mydriatics dilate pupils, causing photophobia. A dimly lit room reduces discomfort from light sensitivity. Warm temperatures, humid air, or quiet environments do not address this primary issue.
Question 4 of 5
A client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?
Correct Answer: D
Rationale: Metronidazole with alcohol causes a disulfiram-like reaction (flushing, nausea). Avoiding alcohol during and 48 hours post-treatment is critical. Refrigeration, specific water intake, or post-meal dosing are not required.
Question 5 of 5
The nurse administers naloxone to a client with opioid-induced respiratory depression. One hour later, nursing assessment reveals that the client has a respiratory rate of 4 breaths/minute, oxygen saturation of 75%, and is unable to be aroused. Which action should the nurse implement?
Correct Answer: B
Rationale: Persistent respiratory depression (4 breaths/min, 75% saturation) indicates ongoing opioid toxicity. Naloxone’s short half-life may require a second dose to reverse opioid effects. Chest tubes, GCS, or CPR do not address the opioid-related cause.
