. A nurse is discussing management of hypertension with a patient. Which patient statement indicates that additional teaching about the relationship between hypertension and acute coronary syndrome (ACS) is needed?

A.

"Controlling my blood pressure will decrease my risk of having a heart attack to some degree."

B.

"Because I'm over 80, even a 20 mm Hg drop in my blood pressure can reduce my risk."

C.

"High blood pressure will increase my body's need for oxygen and increase my heart's workload."

D.

"My high blood pressure has no relationship to the severity of heart disease or its outcomes."

Answer and Explanation

The Correct Answer is D

A. "Controlling my blood pressure will decrease my risk of having a heart attack to some degree." This statement is accurate. Controlling blood pressure reduces the risk of developing ACS.

B. "Because I'm over 80, even a 20 mm Hg drop in my blood pressure can reduce my risk." Research indicates that even modest reductions in blood pressure can significantly lower the risk of cardiovascular events, especially in older adults.

C. "High blood pressure will increase my body's need for oxygen and increase my heart's workload." High blood pressure increases myocardial oxygen demand and can lead to ischemia, which is a precursor to ACS.

D. "My high blood pressure has no relationship to the severity of heart disease or its outcomes." This statement is false. High blood pressure is a major risk factor for heart disease, including ACS, and it directly affects the severity and outcomes of heart disease.

Correct Answer is B

Explanation

A. Inability of the liver to manufacture bile: This does not directly cause esophageal varices or bleeding.

B. A scarred liver results in Portal Hypertension: Cirrhosis leads to scarring of the liver, which increases resistance to blood flow and causes portal hypertension. This elevated pressure in the portal venous system leads to the development of esophageal varices, which can rupture and bleed.

C. An elevated level of copper: Elevated copper levels are associated with Wilson's disease, not the cause of esophageal variceal bleeding in cirrhosis.

D. Inability of the liver to convert NH3 to urea: This causes hepatic encephalopathy but is not related to variceal bleeding.

Correct Answer is B

Explanation

A. Respiratory acidosis: Respiratory acidosis would present with a low pH (below 7.35) and a high PaCO2 (above 45 mmHg).

B. Respiratory alkalosis: This ABG shows a high pH (7.51), low PaCO2 (32 mmHg), and normal HCO3- (26 mEq/L), indicating respiratory alkalosis, typically due to hyperventilation.

C. Metabolic acidosis: Metabolic acidosis would present with a low pH and low HCO3-, but in this case, the HCO3- is normal.

D. Metabolic alkalosis: Metabolic alkalosis would show a high pH and high HCO3-, but the HCO3- in this ABG is normal.
