Jennifer takes birth control pills. Recently she was diagnosed with a urinary tract infection and is taking ciprofloxacin (Cipro). To maximize the therapeutic effects of both types of drugs, what should the nurse tell Jennifer?
Treat the urinary tract infection with another drug
Continue with both therapies simultaneously
Complete the ciprofloxacin therapy and use a backup method of contraception
Abstain from sexual activity until the end of ciprofloxacin therapy
The Correct Answer is C
A. Treat the urinary tract infection with another drug: This might be necessary if ciprofloxacin interacts significantly with birth control pills, but it's not the first line of action.
B. Continue with both therapies simultaneously: Some antibiotics can decrease the effectiveness of birth control pills. It's important to advise using a backup method during and for a short time after ciprofloxacin therapy.
C. Complete the ciprofloxacin therapy and use a backup method of contraception: This is the most appropriate advice. Jennifer should finish the antibiotic to treat the infection, but a backup method (like condoms) is needed to prevent pregnancy because ciprofloxacin might decrease the effectiveness of birth control pills.
D. Abstain from sexual activity until the end of ciprofloxacin therapy: While this would be completely effective, it might not be realistic for everyone. Using a backup method offers protection while still allowing sexual activity.

Correct Answer is C
Explanation
A. She enjoys an alcoholic beverage twice a week: While alcohol can affect kidney function, occasional moderate intake might not be a major concern for vancomycin.
B. She remains outdoors for long periods of time: Sun exposure is not a major concern for vancomycin.
C. She only has one functioning kidney: This is the most significant factor. Vancomycin is primarily excreted by the kidneys. With only one functioning kidney, there's an increased risk of drug accumulation and potential toxicity if the dose is not adjusted for renal function.
D. She has hypertension: Hypertension itself might not significantly affect vancomycin use, although some medications for hypertension can interact with other drugs.
Correct Answer is ["0.5"]
Explanation
To determine the correct volume to administer, we use the formula for calculating the dose:
Volume to administer=Prescribed dose ÷ Available concentration
Given:
● Prescribed dose: 1 mg
● Available concentration: 1 mg per 0.5 mL
Plugging in the values:
Volume to administer=1 mg÷ 1 mg/0.5 ml
Perform the division:
Volume to administer=0.5 mL
So, the nurse should administer 0.5 mL per dose.
Since the question specifies rounding to the nearest tenth and to use a leading zero if it applies (and not to use a trailing zero), the final answer is: 0.5 mL
