A nurse is preparing to administer cefacior to a preschooler who weighs 20 kg. The child is to receive cefacior 30 mg/kg/day to divide equally every 8 hr. Available is cefaclor suspension 125 mg/5 mL. How many mL should the nurse administer for one dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8"]
To calculate the dose;
Weight= 20kg
Dose = 30mg/kg/day 8 hourly
Dose per day = 2030= 600mg
8hourly dose= 600/3= 200mg
Volume to give
125mg= 5ml
200mg = 2005/125
= 8ml

Correct Answer is D
Explanation
A. Client's healthcare power of attorney - This is important legal information but not the most immediate concern for the healthcare provider.
B. Currently prescribed medications - While important, this information does not represent an immediate change in the client's condition.
C. Fall at home as reason for admission - This is background information and, although important, is not the most pressing issue if the client's condition is worsening.
D. Increasing confusion of the client - The increasing confusion could indicate a change in the client's baseline mental status, which could be a sign of a serious condition such as a subdural hematoma or infection and should be communicated immediately.
Correct Answer is B
Explanation
A. Remove the catheter and palpate the client's bladder for residual distention:
This is not the next appropriate action. Palpating the bladder does not address the immediate need to relieve the remaining urine or monitor for signs of overdistension.
B. Allow the bladder to empty completely or up to 1,000 mL of urine:
Gradual emptying is recommended to prevent bladder spasms and circulatory compromise due to rapid decompression of a distended bladder. It is safe to continue draining the urine up to 1,000 mL in a controlled manner before considering clamping the catheter temporarily if needed.
C. Clamp the catheter for thirty minutes and then resume draining:
Clamping after draining only 500 mL is unnecessary. The bladder should be allowed to empty up to 1,000 mL first, as gradual decompression is generally safe and therapeutic. Clamping prematurely might cause unnecessary discomfort or delay effective bladder emptying.
D. Remove the catheter and replace with an indwelling catheter:
Replacing the catheter is not required unless there is a clinical indication, such as repeated urinary retention or prolonged voiding difficulties. A straight catheter is appropriate for one-time use unless otherwise specified.
