Question 1 of 4
A client has been diagnosed with tuberculosis. How long does the nurse anticipate this client will require treatment?
Correct Answer: B
Rationale: The correct answer is B: 6-12 months. Tuberculosis treatment typically involves a combination of antibiotics taken for an extended period to ensure complete eradication of the bacteria. The standard treatment duration for TB is around 6-12 months to prevent relapse and drug resistance. Shorter durations like 2-4 weeks (
C) or 7-10 days (
D) are insufficient to effectively treat TB, leading to treatment failure. A duration of 36 months (
A) is too long and unnecessary for uncomplicated cases, potentially causing patient non-compliance. In summary, the correct answer of 6-12 months is based on the standard treatment guidelines for tuberculosis, providing adequate time for complete recovery and reducing the risk of recurrence.
Question 2 of 4
Which of the following can be determined using culture and sensitivity tests?
Correct Answer: B
Rationale: The correct answer is B: Microbial susceptibility to an anti-infective. Culture and sensitivity tests help identify the specific microorganism causing an infection and determine which antibiotics it is susceptible to. This information guides healthcare providers in choosing the most effective treatment, ensuring targeted therapy.
A, C, and D are incorrect because culture and sensitivity tests do not directly determine the decision to administer a bactericidal or bacteriostatic drug, the duration of antibacterial therapy, or whether to administer empiric therapy. These decisions are based on clinical judgment, patient factors, and guidelines rather than test results.
Question 3 of 4
A client has been prescribed isoniazid (INI) for tuberculosis. Which foods should the client avoid while taking this medication, as they are high in tyramine? (Select All that Apply.)
Correct Answer: A,B,C,E
Rationale: The correct answer is A, B, C, and E. Tyramine-rich foods can interact with isoniazid, leading to a hypertensive crisis. A. Chocolate, B. Aged cheese, C. Bananas, and E. White wine are high in tyramine, which can cause this dangerous reaction. D. Red meat is not high in tyramine, so it does not need to be avoided.
Question 4 of 4
A nurse instructs the patient that if ciprofloxacin (Cipro) is taken with antacids, absorption is
Correct Answer: D
Rationale: The correct answer is D: Decreased. Ciprofloxacin forms chelates with multivalent cations in antacids, reducing its absorption. This occurs due to the binding of chelates, making the drug unavailable for absorption in the gastrointestinal tract.
Therefore, taking ciprofloxacin with antacids decreases its absorption, potentially reducing its effectiveness.
Choices A, B, and C are incorrect because the presence of antacids interferes with ciprofloxacin absorption, leading to decreased bioavailability.
Question 5 of 4
Mrs. Oza, age 69, has hypertension and has one functioning kidney. She loves chocolates and enjoys an alcoholic beverage twice a week. Her hobby is gardening and she goes for long walks despite having arthritis. Which one of the following pieces of information is likely to have the greatest significance if she is prescribed vancomycin?
Correct Answer: A
Rationale: The correct answer is A: She only has one functioning kidney. Vancomycin is primarily eliminated by the kidneys, and in patients with reduced kidney function, there is a higher risk of vancomycin accumulation leading to toxicity. Mrs. Oza's hypertension (
C) and alcohol consumption (
D) may affect her overall health but are not directly related to vancomycin metabolism. Her outdoor activities (
B) and hobbies are relevant for overall well-being but do not impact vancomycin clearance.
Therefore, the fact that she only has one functioning kidney is the most significant piece of information when prescribing vancomycin to ensure proper dosing and monitoring to prevent adverse effects.
