Question 1 of 5
A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 31
Rationale: Calculate: (500 mL ÷ 240 min) × 15 gtt/mL = 31.25 gtt/min, rounded to 31 gtt/min. This ensures the correct infusion rate for the dextrose solution.
Question 2 of 5
A client is receiving morphine sulfate via a patient-controlled analgesic (PCA) pump postoperatively. Which assessment finding should prompt the nurse to administer a prescribed PRN dose of naloxone?
Correct Answer: B
Rationale: A respiratory rate of 7 breaths/min indicates opioid-induced respiratory depression, warranting naloxone to reverse effects. Subjective distress, wheezing, or low oxygen saturation are less specific.
Question 3 of 5
A client who is newly diagnosed with diabetes insipidus is receiving a synthetic vasopressin intravenously. Which side effect of vasopressin reported by the client should the nurse report to the healthcare provider?
Correct Answer: A
Rationale: Worsening headache may indicate vasopressin-induced vasoconstriction or water intoxication, requiring immediate reporting. Polyuria, polydipsia, and low urine specific gravity are diabetes insipidus symptoms, not vasopressin side effects.
Question 4 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.
Question 5 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.
