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 B

Explanation

A. Increase calcium in the diet: While calcium is important, it's not the most critical aspect in managing hypertension compared to weight management.

B. Monitor weight on a weekly basis: Weight management is crucial for clients with hypertension, as fluctuations can indicate changes in fluid retention or overall health. Regular monitoring can help in managing blood pressure.

C. Obtain blood pressure checks twice a year: This is insufficient for monitoring hypertension; more frequent checks are generally recommended.

D. Have yearly eye examinations: While important for overall health, it’s not as directly related to the management of hypertension as monitoring weight.

A. Furosemide 40 mg PO daily for a client whose blood pressure is 123986. B. Nitroglycerin 0.4 mg SL PRN for a client complaining of chest C. Metoprolol 25 mg PO bid for a client whose heart rate is 55 beats D. Diltiazem 30 mg PO tid for a client whose heart rate is 90 beats/min

Correct Answer is B

Explanation

A) Furosemide 40 mg PO daily for a client whose blood pressure is 123/86: While furosemide is important for managing fluid status, the client's blood pressure is within a normal range, and this medication does not address any acute concerns.

B) Nitroglycerin 0.4 mg SL PRN for a client complaining of chest pain: This prescription should be implemented first because it addresses an immediate and potentially life-threatening symptom. Chest pain can indicate angina or myocardial infarction, making it critical to relieve this symptom promptly.

C) Metoprolol 25 mg PO bid for a client whose heart rate is 55 beats: While metoprolol is important for managing heart rate and hypertension, a heart rate of 55 beats/minute is on the lower end and could warrant caution. The priority would be to assess the need for medication before administering it.

D) Diltiazem 30 mg PO tid for a client whose heart rate is 90 beats/min: This medication is also important for managing heart rate and hypertension but is not the priority over addressing acute chest pain. The client’s heart rate is within a normal range, so this does not require immediate action compared to the nitroglycerin for chest pain.
