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 C
Explanation
Choice A Reason:
Oxygen saturation within this range is generally considered adequate and might not directly correlate with the administration of albumin.
Choice B Reason:
Decrease in protein is incorrect. Albumin infusions are meant to supplement protein levels in the blood, so a decrease in protein wouldn't be an expected finding.
Choice C Reason:
Increase in blood pressure is correct. Albumin infusions can potentially help increase blood volume, leading to an increase in blood pressure. In shock, where there's a significant decrease in blood pressure due to reduced circulating volume, administering albumin or other intravenous fluids can help restore blood volume and consequently raise blood pressure towards a more stable range.
Choice D Reason:
PaCO2 of 30 mm Hg is incorrect. PaCO2 levels are related to respiratory function and the amount of carbon dioxide in the blood. While shock can impact various physiological parameters, a PaCO2 level of 30 mm Hg alone might not be directly tied to the administration of albumin in shock.
Correct Answer is A
Explanation
Choice A Reason:
"I should notify my provider if my stools turn black." This is the appropriate statement. Ferrous gluconate is an iron supplement commonly prescribed to treat or prevent iron deficiency anemia. When taking iron supplements, it's common for stools to become darker or even black in color. This change in stool color is due to the iron and is generally harmless. However, it's essential to inform the healthcare provider about this change because it can also indicate bleeding in the gastrointestinal tract, which requires evaluation.
Choice B Reason:
Taking an antacid with iron supplements can interfere with iron absorption. Antacids may decrease the absorption of iron in the stomach, so it's not recommended to take them together.
Choice C Reason:
While staying upright after taking certain medications can help prevent esophageal irritation or reflux, it's not specifically required with ferrous gluconate.
Choice D Reason:
Taking iron supplements with milk is also not recommended as milk and calcium-containing products can inhibit the absorption of iron. It's generally best to take iron supplements on an empty stomach or with vitamin C to enhance absorption, unless otherwise instructed by the healthcare provider.
