A nurse is caring for a client who has a peripheral IV catheter and a prescription for IV fluid replacement. The nurse should cover the Insertion site with which of the following types of dressing?

A. Limit your sodium intake: While excessive sodium intake may be a concern for individuals with certain health conditions, there is no specific restriction on sodium intake associated with theophylline use. This instruction is not directly relevant to theophylline therapy.
B. Avoid caffeinated beverages (Correct Answer): Caffeine can increase the risk of theophylline toxicity by enhancing its effects. Theophylline is metabolized in the liver, and caffeine can interfere with this process. Therefore, it is advisable for individuals taking theophylline to avoid excessive consumption of caffeinated beverages.
C. Take the medication with meals: Theophylline is often prescribed on an empty stomach because food can decrease its absorption. However, the specific recommendation may vary based on the formulation of the medication. It is important to follow the healthcare provider's instructions regarding when to take theophylline in relation to meals.
D. Restrict milk products: There is no general restriction on milk products associated with theophylline use. However, it's important to note that high-fat meals may affect the absorption of theophylline, so individualized instructions from the healthcare provider should be followed.

A. Cover the medication on the client's skin with a sterile gauze pad:
Nitroglycerin ointment is typically applied directly to the skin, and covering it with a sterile gauze pad is not a common practice. The ointment is absorbed through the skin.
B. Spread the medication over a 12.7 cm (5 in) area of the client's skin:
This is the correct answer. Nitroglycerin ointment is usually applied to a specific area of the skin, and the recommended area is often around 12.7 cm (5 inches). The nurse should spread the ointment evenly over this specified area.
C. Measure the dosage of medication using the applicator paper:
Nitroglycerin ointment is typically measured using a dosing strip or measuring paper provided with the medication. Using the applicator paper to measure the appropriate dosage is a common practice.
D. Apply the medication to the same site for three consecutive days:
Nitroglycerin ointment is often rotated to different sites to prevent local irritation or tolerance. It is not typically applied to the same site for three consecutive days.
