A nurse is reviewing a client's laboratory results and sees that their hemoglobin A1C is 9%. Which of the following statements from the nurse is appropriate?
"Your blood sugar is very unstable."
"Your blood sugar is too high after meals."
"Your average blood sugar is high."
"You have many dangerously low blood sugar levels."
The Correct Answer is C
A. "Your blood sugar is very unstable." While high HbA1C levels can indicate poor glucose control, they do not specifically indicate instability in blood sugar levels (i.e., frequent fluctuations between high and low levels). HbA1C does not capture short-term variations in blood glucose; it only provides an average over a few months.
B. "Your blood sugar is too high after meals." Although postprandial (after-meal) glucose levels contribute to overall blood glucose levels, HbA1C measures the average blood glucose level over several months and is not specific to postprandial glucose levels. A high HbA1C suggests elevated glucose levels overall, not just after meals.
C. "Your average blood sugar is high." HbA1C measures the average blood sugar level over an extended period, typically 2-3 months. A result of 9% indicates that the client's average blood glucose levels have been consistently high, suggesting poor long-term glucose control. This is a precise and appropriate statement reflecting the meaning of the HbA1C result.
D. "You have many dangerously low blood sugar levels." A high HbA1C indicates elevated blood glucose levels over time, not low levels. Low blood sugar levels (hypoglycemia) would not contribute to a high HbA1C. In fact, frequent hypoglycemia would more likely result in a lower HbA1C, not a higher one.

Correct Answer is D
Explanation
A. Anti-inflammatory: While aspirin does have anti-inflammatory properties, it is not given for this purpose in the context of preventing heart attacks. The anti-inflammatory action is more relevant in conditions like arthritis.
B. Analgesic: Aspirin is an analgesic and can relieve pain, but this is not the primary reason for its use in clients with a history of myocardial infarction.
C. Antipyretic: Aspirin has antipyretic properties, meaning it can reduce fever, but this is not the reason it is prescribed following a myocardial infarction.
D. Antiplatelet aggregate: Aspirin is used in clients with a history of myocardial infarction for its antiplatelet properties. It helps to prevent the aggregation of platelets, thereby reducing the risk of blood clots that can lead to another heart attack.
Correct Answer is A
Explanation
A. Carvedilol: Carvedilol is a beta-blocker that can worsen asthma symptoms because it can cause bronchoconstriction. Non-selective beta-blockers like carvedilol can exacerbate respiratory conditions and should be used with caution in asthmatic patients.
B. Isosorbide dinitrate: Isosorbide dinitrate is a vasodilator used to reduce the workload on the heart by dilating blood vessels. It does not affect respiratory function and is safe for use in clients with asthma.
C. Fluticasone: Fluticasone is a corticosteroid used to manage asthma by reducing inflammation in the airways. It is beneficial for clients with asthma and does not require clarification.
D. Captopril: Captopril is an ACE inhibitor used to treat heart failure. It does not directly affect asthma and is generally safe for use in clients with respiratory conditions.
