Isosorbide mononitrate modified release formula is structured to provide a nitrate free period. The nurse understands that the rationale for this period is to:

decrease allergic reactions

decrease tolerance to effects

prevent reflex tachycardia

increase absorption

Answer and Explanation

The Correct Answer is B

A. Decrease allergic reactions: Nitrate-free periods are not primarily designed to address allergic reactions.

B. Decrease tolerance to effects: Nitrates, including isosorbide mononitrate, can lead to the development of tolerance when used continuously. The nitrate-free period helps to minimize this tolerance, allowing the medication to remain effective over time.

C. Prevent reflex tachycardia: While nitrate use can sometimes cause reflex tachycardia, the nitrate-free interval is not specifically aimed at preventing this.

D. Increase absorption: The nitrate-free period does not influence the absorption of the medication itself.

Correct Answer is C

Explanation

A. "I will remove the tablets from the bottle and keep in a plastic bag in my handbag." This statement is incorrect because nitroglycerin tablets should be kept in their original amber bottle to protect them from light and moisture. Storing them in a plastic bag can compromise their effectiveness.

B. "I will obtain a new prescription every two months so it doesn't expire." While it is important to replace expired medication, nitroglycerin tablets typically have a shelf life of 6 months to 1 year, depending on the formulation. The client should be educated on checking expiration dates rather than just obtaining a new prescription regularly.

C. "I will call 911 if I get chest pain that doesn't go away after taking one tablet." This statement indicates understanding of the importance of seeking emergency help if chest pain persists after taking nitroglycerin, as it may signify a more serious condition requiring immediate medical attention.

D. "I will leave my bottle of nitroglycerin at home in the medicine cabinet." This is inappropriate because nitroglycerin should be easily accessible, ideally kept with the client at all times, especially when they might experience chest pain.

A. 47-year-old male construction foreman who takes atenolol. B. 43-year-old female with Crohn's disease C. 58-year-old male who smokes one pack of cigarettes per day. D. 23-year-old female who drinks a glass of wine with dinner.

Correct Answer is B

Explanation

A. 47-year-old male construction foreman who takes atenolol: Atenolol is a beta-blocker used for hypertension and does not typically contribute to folic acid deficiency. This client’s occupation and medication are not directly associated with folate deficiency.

B. 43-year-old female with Crohn's disease: This client is at high risk for folic acid deficiency due to the malabsorption issues commonly associated with Crohn's disease. Inflammatory bowel diseases can impair the absorption of nutrients, including folate, making this client the most likely candidate for folic acid deficiency.

C. 58-year-old male who smokes one pack of cigarettes per day: Smoking is associated with various health risks, but it does not directly correlate with folic acid deficiency. This client may face other health issues, but folate deficiency is not specifically indicated.

D. 23-year-old female who drinks a glass of wine with dinner: Moderate alcohol consumption may affect folate metabolism, but a single glass of wine is unlikely to cause a significant deficiency. Other factors would need to be considered for a diagnosis of folate deficiency.
