A nurse is calculating fluid input for a client who is receiving a continuous IV infusion of 0.9% sodium chloride at 125 mL/hr and cefazolin 50 mL IV bolus every 4 hr. How many mL did the client receive per IV infusion over the past 24 hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3300"]
Calculation:
- Calculate the total volume from the continuous IV infusion over 24 hours.
Continuous infusion rate = 125 mL/hr
Time = 24 hr
Volume from continuous infusion = 125 mL/hr × 24 hr
= 3000 mL.
- Calculate the total volume from the cefazolin IV bolus over 24 hours.
Cefazolin bolus volume per dose = 50 mL
Frequency = every 4 hr
Number of doses in 24 hr = 24 hr / 4 hr/dose
= 6 doses.
Volume from cefazolin bolus = 50 mL/dose × 6 doses
= 300 mL.
- Calculate the total IV fluid intake over 24 hours.
Total IV fluid intake = Volume from continuous infusion + Volume from cefazolin bolus
= 3000 mL + 300 mL
= 3300 mL.

Correct Answer is A
Explanation
Rationale:
A. Poached egg: A poached egg is a good choice for a client with ulcerative colitis as it is easy to digest and does not irritate the gastrointestinal tract. Eggs provide protein without the fiber that could exacerbate diarrhea.
B. Fresh peaches: Fresh peaches are high in fiber, which can aggravate diarrhea in clients with ulcerative colitis. Clients should avoid high-fiber fruits, especially during flare-ups.
C. Whole grain toast: Whole grain toast contains a high amount of fiber, which may irritate the intestines and worsen diarrhea. A low-fiber diet is typically recommended during flare-ups of ulcerative colitis.
D. Oatmeal: Oatmeal is high in fiber, which can be problematic for clients with ulcerative colitis, especially during episodes of diarrhea. It can irritate the digestive system and increase discomfort.
Correct Answer is A
Explanation
Rationale:
A. "Position the client on a flat surface." Positioning the client on a flat surface is essential for effective defibrillation. A flat surface ensures the chest is stable, allowing the AED to deliver a shock more effectively and improving the chances of a successful resuscitation.
B. "Perform CPR while the AED is analyzing." CPR should be paused while the AED is analyzing to ensure accurate analysis. Performing CPR during analysis can interfere with the AED's ability to correctly assess the heart's rhythm and may delay shock delivery.
C. "Set the AED to 80 joules." Most AEDs are preset to deliver appropriate shock levels, usually between 120-200 joules, and should not be manually adjusted unless specified by the device’s instructions.
D. "Use an AED for a client who has atrial fibrillation." An AED is used to treat life-threatening arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia. Atrial fibrillation does not require defibrillation unless it progresses to a more serious arrhythmia.
