Question 1 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.
Question 2 of 5
Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?
Correct Answer: D
Rationale: Insulin lispro, rapid-acting, peaks 1-2 hours post-dose, requiring meals shortly after to prevent hypoglycemia. Synchronizing meal timing is critical. Glucose sources, monitoring, and hypoglycemia checks are secondary.
Question 3 of 5
When caring for a client with diabetes insipidus who is receiving an antidiuretic hormone intranasally, which serum laboratory test is most important for the nurse to monitor?
Correct Answer: B
Rationale: Antidiuretic hormone (ADH) regulates water reabsorption, affecting serum osmolality. Monitoring osmolality assesses ADH therapy effectiveness in maintaining fluid balance in diabetes insipidus. Platelets, glucose, and calcium are not directly impacted by ADH or diabetes insipidus management.
Question 4 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 5 of 5
The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client?
Correct Answer: C
Rationale: Adalimumab’s immunosuppression increases infection risk. Avoiding crowds and sick individuals minimizes exposure. Eye exams are more relevant for methotrexate, chest x-rays are not routine, and live vaccines may be contraindicated.
