A nurse is providing discharge dietary teaching to a client who has a new prescription for theophylline. Which of the following instructions should the nurse include?
"Limit your sodium intake."
"Restrict milk products."
"Avoid caffeinated beverages."
"Take the medication with meals."
The Correct Answer is C
Choice A Reason:
"Limit your sodium intake." Is incorrect. Sodium restriction might be appropriate for some cardiovascular or renal conditions, but it is not specifically related to theophylline use.
Choice B Reason:
"Restrict milk products." is incorrect. Restricting milk products is not a necessary dietary consideration for theophylline. However, consuming high-fat dairy products may delay the absorption of theophylline, potentially affecting its effectiveness.
Choice C Reason:
"Avoid caffeinated beverages." Is correct. Theophylline is a bronchodilator used to treat respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD). It belongs to the class of methylxanthine medications and acts similarly to caffeine. Consuming additional caffeine through beverages like coffee, tea, or certain sodas can increase the risk of adverse effects associated with theophylline, such as increased heart rate or nervousness. Hence, avoiding caffeinated beverages is advisable to minimize the risk of exacerbating these effects.
Choice D Reason:
"Take the medication with meals." Taking theophylline with or without meals is typically acceptable, but it's essential to maintain consistency in timing and avoid significant changes in dietary habits that might affect its absorption or metabolism.

Correct Answer is B
Explanation
Choice A Reason:
BUN 15 mg/dL (blood urea nitrogen) is incorrect. An elevated BUN level can indicate kidney dysfunction or dehydration, but it's not typically associated with azathioprine's adverse effects. Azathioprine is known to affect bone marrow, leading to decreased blood cell counts, rather than directly impacting kidney function.
Choice B Reason:
WBC 3,000/mm³ (low white blood cell count) is correct. Azathioprine is an immunosuppressive medication used to treat various conditions, including rheumatoid arthritis. One of its known adverse effects is bone marrow suppression, which can lead to decreased production of blood cells, including white blood cells (WBCs). A low WBC count (leukopenia) can increase the risk of infections due to compromised immune function, making it an important adverse effect to monitor in individuals taking azathioprine.
Choice C Reason:
Hct 45% (hematocrit) is incorrect. A hematocrit of 45% is within the normal range for both men and women. Azathioprine adverse effects usually manifest as blood cell-related issues (such as leukopenia) rather than directly impacting hematocrit levels.
Choice D Reason:
Platelets 250,000/mm³: Platelets within the range of 150,000 to 400,000/mm³ are considered normal. Azathioprine typically affects white blood cells more prominently than platelet counts.
Correct Answer is C
Explanation
Choice A Reason:
Withdrawing the NPH insulin from the vial should come after injecting air into the NPH vial.
Choice B Reason:
Injecting air into the regular insulin vial should occur after withdrawing the NPH insulin from its vial.
Choice C Reason:
Inject air into the NPH vial is correct. The sequence for mixing regular insulin (clear) and NPH insulin (cloudy) in the same syringe typically involves injecting air into the NPH (cloudy) insulin vial first. This step prevents excess pressure buildup when withdrawing the solution, making it easier to draw the correct amount of NPH insulin into the syringe.
Choice D Reason:
Withdrawing the regular insulin from the vial should occur after withdrawing the correct amount of NPH insulin into the syringe.
