Extract:
Question 1 of 5
A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
Correct Answer: 125
Rationale:
To calculate the infusion rate, divide the total volume (1000 mL) by the infusion time (8 hours): 1000 ÷ 8 = 125 mL/hr.
Question 2 of 5
A hospice nurse is caring for a client who has terminal cancer and takes PO morphine for pain relief. The client reports that he had to increase the dose of morphine this week to obtain pain relief. Which of the following scenarios should the nurse document as the explanation for this situation?
Correct Answer: A
Rationale:
Tolerance to opioids like morphine requires higher doses over time for the same pain relief, common in terminal cancer pain management. Confusion, improper use, or addiction are less likely explanations.
Question 3 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: D
Rationale: Codeine can cause dizziness or orthostatic hypotension, so changing positions slowly prevents falls. It causes constipation, not diarrhea, should not be combined with alcohol, and is better taken with food.
Question 4 of 5
A nurse is assessing a client who has schizophrenia and is taking risperidone. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Weight gain is a common side effect of risperidone due to its effects on metabolism and appetite. Bradycardia, dependent edema, and nightmares are not typically associated with risperidone.
Question 5 of 5
A nurse is preparing to administer phenytoin 50 mg IV bolus to a client who has a seizure disorder. The medication is supplied as a 50 mg/mL vial. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Administering phenytoin over at least 1 minute reduces complications like hypotension. It should be diluted with saline, not sterile water, and not injected if crystallized.
