A nurse is teaching a client who has angina about sublingual nitroglycerin. Which of the following instructions should the nurse include?
Lie down when taking the mediation.
Chew the medication thoroughly.
Store the medication in the refrigerator.
Check the expiration date on the medication every 6 months.
The Correct Answer is A
A. Lie down when taking the medication: Sublingual nitroglycerin causes vasodilation, which can lower blood pressure and potentially cause dizziness or fainting. The client should lie down or sit in a comfortable position to minimize the risk of falls or injury.
B. Chew the medication thoroughly: Sublingual nitroglycerin should be placed under the tongue and allowed to dissolve completely, not chewed. Chewing may affect the absorption and effectiveness of the medication.
C. Store the medication in the refrigerator: Sublingual nitroglycerin should be stored at room temperature, away from moisture and heat, not in the refrigerator. Cold storage could reduce the medication's effectiveness.
D. Check the expiration date on the medication every 6 months: While it is important to check the expiration date, every 6 months is not sufficient. The client should check the expiration date more frequently (e.g., every 3 months) and replace the medication if expired to ensure it is effective when needed.

Correct Answer is B
Explanation
A. It is important to provide the client with all options available, including risks, benefits, and alternatives to the surgery. Telling the client that the procedure is the only option may limit their autonomy and decision-making ability.
B. The nurse should reinforce the information already provided by the surgeon and clarify any questions the client may have. This ensures that the client is fully informed and can make an educated decision about their care. Encouraging open communication helps the client feel more comfortable with their decision.
C. This response disregards the client’s right to make decisions about their own care. The client must be given the opportunity to express concerns and make an informed choice about their treatment.
D. Persuading the client to undergo surgery is not appropriate. The nurse should support the client’s decision-making process, providing clear and accurate information while respecting their autonomy. Coercion is unethical and does not align with patient-centered care.
Correct Answer is ["30"]
Explanation
Calculation:
- Determine the concentration of the available lidocaine solution in milligrams per milliliter (mg/mL).
Available concentration = Total medication (mg) / Total volume (mL)
= 400 mg / 100 mL
= 4 mg/mL.
- Convert the desired dose from milligrams per minute (mg/min) to milligrams per hour (mg/hr).
1 hr = 60 min
Desired dose in mg/hr = 2 mg/min × 60 min/hr
= 120 mg/hr.
- Calculate the IV pump rate in milliliters per hour (mL/hr).
IV pump rate (mL/hr) = Desired dose (mg/hr) / Available concentration (mg/mL)
= 120 mg/hr / 4 mg/mL
= 30 mL/hr.
