Strategy Session: Client Need 4

Pharmacological and Parenteral Therapies Subcategory

Question Type: Analysis
Strategy Used: Determine Effects

Consider this example:

A 45-year old homeless man is hospitalized with tuberculosis. The physician's orders include isoniazid (INH) and pyridoxine (vitamin B₆). The patient asks why he is receiving pyridoxine. The nurse's response should be based on the knowledge that pyridoxine:

(1)		increases INH absorption.

(2)		prevents the development of tolerance to INH.

(3)		decreases the severity of INH side effects.

(4)		prevents INH-associated neuritis.

Applying the strategy: First, reword the question in your own words. Why is vitamin B₆ given to a patient together with INH? Next, determine the effects of each response. Answer choice 1: there is no effect. Answer choice 2: tolerance does not develop. Answer choice 3: there is no effect. Answer choice 4: most common untoward effect, frequently seen in malnourished infants, alcoholics, and diabetic patients. What response actually positions vitamin B₆ as having an effect response? The correct answer is (4).
