The nurse is teaching a patient about rifampin. Which statement by the patient indicates understanding of the teaching?
- A. I should not wear soft contact lenses while taking rifampin
- B. I will need regular eye examinations while taking this drug
- C. I will report orange urine to my provider immediately
- D. I understand that renal toxicity is a common adverse effect
Correct Answer: A
Rationale: Rifampin stains fluids red-orange, risking soft lens damage; eye exams are for ethambutol, and urine color is benign. Patients taking rifampin should be warned that urine, feces, saliva, sputum, sweat, and tears may turn a harmless red-orange color.

Which one of the following is a fundamental difference between competitive and noncompetitive antagonist?
- A. Competitive and non competitive work on different receptors
- B. Competitive antagonist reduces agonist potency (increase EC50) and non competitive antagonist reduces agonist efficacy (decrease E max)
- C. There is no difference between them, they are exactly the same
- D. Non competitive antagonist causes an upward shift of the E max while competitive antagonist does the opposite
Correct Answer: B
Rationale: Competitive antagonists shift potency (EC50), while noncompetitive reduce efficacy (Emax), a key pharmacological distinction.
A patient has come to the clinic and been diagnosed with Lyme disease. The physician has ordered oral tetracycline. What is important for the nurse to include in the teaching plan about tetracycline? (Select all that apply.)
- A. Do not take the drug with anything high in sodium content to keep from producing a state of hypernatremia in the body.
- B. Do not take the drug with foods or other drugs that contain calcium.
- C. Avoid eating bananas at the same time you take this drug as the potassium content of the tetracycline can produce hyperkalemia in the body.
- D. Avoid exposure to the sun when taking this drug as it can turn your skin purple.
Correct Answer: B
Rationale: The antibiotic tetracycline is not absorbed from the gastrointestinal (GI) tract if calcium or calcium products (e.g., milk) are present in the stomach. It cannot be taken with iron products because a chemical reaction occurs preventing absorption. Although tetracycline can increase sun sensitivity, it does not turn the skin purple. Patients who take tetracycline do not need to avoid eating bananas or foods that are high in potassium.
Drugs that are prone to cause adverse drug effects include:
- A. Diuretics
- B. Inhaled anticholinergics

Correct Answer: D
Rationale: Stimulants frequently cause ADRs (e.g., tachycardia), though diuretics and insulins also have risks; anticholinergics are less broad.
