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 ["7.5"]
Explanation
To calculate the amount of potassium chloride elixir needed per dose, we can use the following formula:
Amount per dose (mL) = (Desired dose in mEq / Concentration in mEq/mL) * Volume in mL
Given:
Desired dose = 20 mEq/day divided equally every 12 hr = 10 mEq/dose
Concentration = 6.7 mEq/5 mL
Plugging in the values:
Amount per dose (mL) = (10 mEq / 6.7 mEq/5 mL) * 5 mL
Calculating:
Amount per dose (mL) ≈ 7.46 mL
Rounded to the nearest tenth, the nurse should administer approximately 7.5 mL of the potassium chloride elixir per dose.
Correct Answer is D
Explanation
A. "Decrease your daily sodium intake."
Incorrect Explanation: This instruction is appropriate for a client taking lithium carbonate.
Explanation: Lithium is a mood-stabilizing medication commonly prescribed for conditions like bipolar disorder. High levels of sodium can lead to increased lithium retention in the body, potentially raising the risk of toxicity. Advising the client to decrease their daily sodium intake helps prevent this.
B. "Take this medication 2 hours before a meal."
Incorrect Explanation: This instruction is not accurate for lithium carbonate.
Explanation: Lithium carbonate is typically taken with food or milk to help minimize stomach upset. Taking it on an empty stomach might increase the risk of gastrointestinal side effects.
C. "Limit foods containing tyramine."
Incorrect Explanation: This instruction is not directly relevant to lithium carbonate.
Explanation: Tyramine is a compound found in some foods and can interact with certain medications like monoamine oxidase inhibitors (MAOIs), but it is not a primary concern with lithium carbonate.
D. "Report swelling of the feet to your provider."
Correct Explanation: This instruction is appropriate for a client taking lithium carbonate.
Explanation: Lithium can lead to water retention, which might result in swelling, particularly in the feet and ankles. Reporting swelling is important as it can be an early sign of potential side effects or changes in kidney function.
