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 A
Explanation
Choice A Reason:
Visual disturbances is the correct findings. In individuals taking digoxin, visual disturbances such as blurred or yellow-tinted vision can indicate early signs of medication toxicity. This symptom often requires prompt medical attention, as it can precede more severe complications.
Choice B Reason:
Sudden weight gain is not correct. While weight gain can be a symptom of worsening heart failure, it's not typically associated specifically with digoxin toxicity. It's more commonly related to fluid retention in heart failure.
Choice C Reason:
Potassium 4.4 mEq/L is not correct. This potassium level is within the normal range. Digoxin toxicity can be exacerbated by low potassium levels, but a normal potassium level doesn't directly indicate digoxin toxicity.
Choice D Reason:
Insomnia is not a typical early sign of digoxin toxicity. It's more commonly associated with issues like difficulty sleeping rather than being a direct symptom of digoxin toxicity.
Correct Answer is C
Explanation
Choice A Reason:
Increase in serum glucose is incorrect. Desmopressin, which is a synthetic form of vasopressin, primarily affects water reabsorption in the kidneys and doesn't directly impact glucose levels. Therefore, an increase in serum glucose wouldn't be an expected therapeutic response to desmopressin for diabetes insipidus.
Choice B Reason:
Decrease in blood pressure is incorrect. Desmopressin is primarily used for its antidiuretic effect, concentrating urine by increasing water reabsorption in the kidneys. It typically doesn't have a significant impact on blood pressure. Therefore, a decrease in blood pressure wouldn't typically be an anticipated therapeutic response to desmopressin in this context.
Choice C Reason:
Decrease in urine output is correct. Desmopressin is a synthetic form of vasopressin (antidiuretic hormone) used to treat diabetes insipidus, a condition characterized by excessive urination and extreme thirst due to the inability to concentrate urine. The primary goal of desmopressin is to reduce urine output by increasing water reabsorption in the kidneys, thereby decreasing excessive urination. Therefore, a decrease in urine output would indicate a therapeutic response to the medication in this context.
Choice D Reason:
Increase in WBC count is incorrect. Desmopressin's action is centered on affecting kidney function by regulating water reabsorption and does not involve changes in white blood cell count. Consequently, an increase in WBC count wouldn't be an expected therapeutic response to desmopressin for diabetes insipidus.
