A nurse is teaching a client who has a new prescription for nitroglycerin sublingual tablets for treating angina. Which of the following instructions should the nurse include in the teaching?

A) Lactated Ringer's: Lactated Ringer's solution is not app’opriate in this si’uation because it does not provide the necessary nutrients found in TPN. It is primarily used for fluid replacement and maintenance and does not contain the essential macronutrients required for TPN.

B) Dextrose 10% in water: This is the correct fluid to administer when the current bag of TPN has finished infusing and the next bag is not yet available. Dextrose 10% in water provides a source of glucose, which can help prevent hypoglycemia in clients dependent on TPN. While it does not provide the full spectrum of nutrients found in TPN, it can temporarily meet the client's caloric needs until the next bag of TP’ becomes available.

C) 0.45% sodium chloride: This solution, also known as half-normal saline, is hypotonic and primarily used for hydration and maintenance fluids. It does not provide adequate nutrition and is not a suitable substitute for TPN.

D) 0.9% sodium chloride: This solution, also known as normal saline, is isotonic and used for fluid resuscitation, maintenance, and replacement. Like 0.45% sodium chloride, it does not contain the necessary nutrients for TPN and is not appropriate as a substitute.

A) Ask another nurse if they are aware of potential interactions: Relying solely on another nurse's awareness of potential interactions is’not a comprehensive or reliable approach. Nurses may have varying levels of knowledge about medication interactions, and it's important to consult verified sources ’or accurate information.

B) Check the client's medical record for medication and food’interactions: While the client's medical record may contain information’about their current medications, it may not provide detailed information about potential interactions with specific foods or other medications. Additionally, relying solely on the medical record may not capture recent changes in medication or dietary intake.

C) Consult a drug reference guide for possible interactions: This is the correct action. Drug reference guides provide comprehensive information about medications, including potential interactions with other drugs and food. Nurses can access reliable drug reference guides to ensure they have accurate information before administering medications.

D) Have the client take the medication on an empty stomach to avoid interactions: Instructing the client to take medication on an empty stomach without knowledge of specific interactions could be inappropriate and potentially harmful. Some medications require administration with food to enhance absorption or reduce gastrointestinal side effects. It's essential to consult reliable sources ’o determine the appropriate administration instructions for each medication.
