Extract:
Question 1 of 5
A nurse caring for a client receiving doxycycline for the treatment of Lyme's Disease. Which statement below should be included in the client's teaching plan?
Correct Answer: D
Rationale: Doxycycline should be taken without dairy products, as calcium in dairy can bind to the drug and reduce absorption. Sun exposure increases photosensitivity risk, water is needed to prevent esophageal irritation, and antacids interfere with absorption.
Question 2 of 5
A nurse caring for a client receiving doxycycline for the treatment of Lyme's Disease. Which statement below should be included in the client's teaching plan?
Correct Answer: D
Rationale: Doxycycline should be taken without dairy products, as calcium in dairy can bind to the drug and reduce absorption. Sun exposure increases photosensitivity risk, water is needed to prevent esophageal irritation, and antacids interfere with absorption.
Question 3 of 5
A client exposed to anthrax has presented to the healthcare setting. Which of the following medications below is the treatment for this biological exposure?
Correct Answer: C
Rationale: Ciprofloxacin, a fluoroquinolone, is the recommended first-line antibiotic for treating anthrax exposure due to its efficacy against Bacillus anthracis, the bacteria causing anthrax. Amoxicillin/clavulanate is a broad-spectrum antibiotic but not preferred for anthrax. Nystatin is an antifungal and ineffective against bacterial infections. Tamoxifen is used for breast cancer and has no role in treating anthrax.
Question 4 of 5
A nurse is teaching a client who is beginning highly active antiretroviral therapy (HAART) for HIV which includes zidovudine. The nurse should include teaching regarding which black box warning associated with this medication?
Correct Answer: A
Rationale: Zidovudine carries a black box warning for lactic acidosis, a rare but serious complication. Clients should be educated on symptoms like muscle pain and weakness. It is not associated with uterine cancer, oral candidiasis (though common in HIV), or thromboembolic events.
Question 5 of 5
A client diagnosed with strep throat requires antibiotics for treatment. With an allergy to penicillin, the nurse understands which medication should be avoided due to cross-sensitivity with penicillin medications?
Correct Answer: D
Rationale: Cephalosporins have a beta-lactam structure similar to penicillins, which can cause cross-reactivity in clients with a penicillin allergy, though the risk is lower with newer generations. Macrolides (e.g., azithromycin) are often used as alternatives for penicillin-allergic patients. Antiretrovirals and antimalarials are unrelated to penicillin and do not pose cross-sensitivity risks.
