A nurse is teaching a client who has angina about a new prescription for sublingual nitroglycerin tablets. Which of the following instructions should the nurse include in the teaching?
"Keep the tablets at room temperature in their original glass bottle."
"Discard any tablets you do not use every 6 months."
"Take one tablet each morning 30 minutes prior to eating."
"Place the tablet between your cheek and gum to dissolve
The Correct Answer is D
A. "Keep the tablets at room temperature in their original glass bottle." This is a correct storage instruction. Nitroglycerin tablets are sensitive to heat and light, so they should be stored in their original container, protected from light, and kept at room temperature.
B. "Discard any tablets you do not use every 6 months." This is not an accurate instruction. Nitroglycerin tablets usually have an expiration date printed on the label, and they should be discarded after that date.
C. "Take one tablet each morning 30 minutes prior to eating." This is not an accurate instruction. Sublingual nitroglycerin is taken as needed to relieve angina symptoms, not on a regular schedule like a daily medication.
D. "Place the tablet between your cheek and gum to dissolve."
Sublingual nitroglycerin tablets are used to relieve angina symptoms by causing vasodilation, which increases blood flow to the heart muscle. To take sublingual nitroglycerin tablets effectively, the client should be instructed to place the tablet between the cheek and gum to dissolve. This allows the medication to be absorbed through the mucous membranes in the mouth and enter the bloodstream quickly, providing rapid relief from angina symptoms.

Correct Answer is B
Explanation
A. Pedal edema
Explanation: Pedal edema (swelling of the feet) is not a typical sign of an acute infusion reaction to IV amphotericin B.
B. Fever
Explanation: Fever is a common sign of an acute infusion reaction, indicating an inflammatory response to the medication.
An acute infusion reaction to IV amphotericin B is most commonly characterized by fever and chills, as well as other flu-like symptoms such as headache, muscle or joint pain, and sometimes a dry cough. Fever is a key indicator of an acute reaction to amphotericin B, and the presence of fever during or after administration should raise concern and prompt the nurse to take appropriate action, including notifying the healthcare provider and discontinuing the infusion.
Pedal edema and hyperglycemia are not typically associated with acute infusion reactions to amphotericin B and are not common manifestations of this type of reaction.
C. Hyperglycemia
Explanation: Hyperglycemia (high blood sugar) is not typically associated with an acute infusion reaction to IV amphotericin B.
D. Dry cough
Explanation: A dry cough can be a symptom of an acute infusion reaction, potentially indicating irritation or inflammation of the respiratory tract.
Correct Answer is D
Explanation
A. Another formulation of potassium should be given IV: The type of potassium formulation isn't the issue in this scenario.
B. Potassium chloride should be diluted in dextrose 5% in water: While potassium chloride can be administered in different solutions, the primary concern here is the infusion rate, not the specific diluent.
C. The client should be treated by giving potassium by IV bolus: The concern here is the rate of administration, not the route. Potassium is commonly administered through an IV infusion rather than a bolus due to the risk of cardiac arrhythmias associated with rapid administration.
D. A nurse is caring for a client who is to receive potassium replacement. The nurse should clarify the prescription with the provider because the potassium infusion rate is too rapid.
The prescription indicates that the client should receive potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 minutes. This rate of administration is too fast for potassium replacement and could lead to potentially serious complications, such as hyperkalemia or cardiac arrhythmias. The typical recommended rate for potassium replacement is 10-20 mEq/hour, and this prescription exceeds that range.
