The patient with tuberculosis is now on isoniazid (INH). Which laboratory test should the nurse monitor?

Liver enzymes/ LFTs

PT and PTT

BUN

CBC

Answer and Explanation

The Correct Answer is A

A. Liver enzymes/ LFTs: Correct. Isoniazid (INH) is hepatotoxic and can cause liver damage. Monitoring liver function tests (LFTs) helps detect hepatotoxicity early.
B. PT and PTT: These tests measure blood clotting and are not directly affected by INH.
C. BUN: Blood Urea Nitrogen (BUN) measures kidney function, and while it is important, INH primarily affects the liver.
D. CBC: Complete Blood Count (CBC) is useful for overall health but not specifically for monitoring INH therapy.

Correct Answer is A

Explanation

A. "I will need to postpone my vacation at the beach until I finish this medication."
Tetracycline can cause photosensitivity, making the skin more susceptible to sunburn. Avoiding sun exposure, such as delaying a beach vacation, is a wise precaution.
B. "I will stop taking this medication as soon as I feel better."
This is incorrect because antibiotics should be taken for the full prescribed duration to ensure the infection is fully treated and to prevent antibiotic resistance.
C. "It is fine for me to become pregnant while taking this medication."
Tetracycline is contraindicated during pregnancy due to the risk of harm to the developing fetus, including potential tooth discoloration and inhibited bone growth.
D. "I am so glad to be leaving today because I have an appointment at the tanning salon."
This is incorrect because exposure to UV rays from tanning salons should be avoided due to the risk of photosensitivity and severe sunburn while taking tetracycline

A. Treat the urinary tract infection with another drug B. Continue with both therapies simultaneously C. Complete the ciprofloxacin therapy and use a backup method of contraception D. Abstain from sexual activity until the end of ciprofloxacin therapy

Correct Answer is C

Explanation

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.
