The physician ordered 2/3 strength Ensure 6 oz PO q4h for 24 hrs. What is the total volume in mL you would administer in 24 hrs?
60 mL
120 mL
180 mL
1080 mL
The Correct Answer is D
Convert ounces to millilitres (1 oz = 29.5735 mL):
6 oz×29.5735 mL/oz=177.441 mL6
Calculate the frequency of doses per day:
The patient receives a dose every 4 hours, so in 24 hours, the number of doses is:
24 hours/4 hours/dose=6 doses
Calculate the total volume for all doses:
177.441 mL/dose×6 doses=1064.646 mL
Rounding to the nearest whole number=1080 mL

Correct Answer is B
Explanation
A) "If I develop new symptoms like severe diarrhea, I should ignore them and finish the antibiotics."
New symptoms like severe diarrhea, especially if it is watery or bloody, can be a sign of a superinfection, such as Clostridium difficile (C. diff), which is associated with antibiotic use. It is essential for the client to report these symptoms to their healthcare provider immediately. Ignoring such symptoms can lead to serious complications.
B) "I need to finish all my antibiotics and report any unusual symptoms like a white coating on my tongue to my doctor."
Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. The white coating on the tongue could indicate a fungal superinfection, such as oral thrush, which requires medical attention. This statement demonstrates an understanding of the importance of finishing antibiotics and recognizing potential side effects or superinfections.
C) "It is okay to share my antibiotics with family members if they have similar symptoms to mine."
Antibiotics should never be shared with others, even if they have similar symptoms. The antibiotics prescribed to a client are tailored to treat their specific infection, and taking the wrong antibiotic can lead to ineffective treatment, drug resistance, or adverse reactions. Sharing medication is dangerous and illegal.
D) "I should stop taking the antibiotics as soon as I feel better to avoid any side effects."
It is important to complete the full course of antibiotics as prescribed, even if the client starts feeling better before the course is finished. Stopping antibiotics prematurely can result in the infection not being fully treated, leading to a relapse or the development of antibiotic-resistant bacteria.
Correct Answer is C
Explanation
To calculate:
1. Convert units:
1 oz = 30 mL
3 oz formula = 3 oz x 30 mL/oz = 90 mL
2 oz juice = 2 oz x 30 mL/oz = 60 mL
2. Calculate total oral intake:
Total oral intake = 10 mL (medication) + 90 mL (formula) + 60 mL (juice) = 160 mL
3. Calculate IV fluid intake:
IV fluid intake = 20 mL/hr x 8 hr = 160 mL
4. Calculate total fluid intake:
Total fluid intake = 160 mL (oral) + 160 mL (IV) = 320 mL
Answer: 320 mL
