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 A
Explanation
Given:
Volume of fluid: 100 mL
Infusion time: 45 minutes
Step 1: Convert infusion time to hours:
Infusion time (hr) = 45 min / 60 min/hr
Infusion time (hr) = 0.75 hr
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = Volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 100 mL / 0.75 hr
Flow rate (mL/hr) = 133.3333333 mL/hr
Step 3: Round to the nearest whole number:
Flow rate (mL/hr) ≈ 133 mL/hr
