An older adult patient is taking phenobarbital (Luminal) for seizure control. What is most important for the nurse to assess in the patient?

1. Fluid intake
2. Electrolyte balance
3. Respiratory function
4. Nutritional status

Question 2

The nurse is conducting an education class about myocardial blood supply for patients with coronary artery disease (CAD). The nurse determines that learning has occurred when the patients make which statements.

1. The heart has right and left arteries that arise from the aorta.
2. The coronary arteries carry blood away from the heart to the right atrium.
3. The heart receives its oxygen through the blood that fills it.
4. Coronary arteries primarily carry blood to the left ventricle.
5. The right and left arteries have smaller branches that go around the heart.

Answer to Question 1

3
Rationale 1: Fluid intake is often decreased in older adults but is not a side effect of barbiturates.
Rationale 2: Barbiturates do not affect electrolyte balance.
Rationale 3: Older adults are at risk for cumulative effects of barbiturates due to diminished hepatic and renal function. Central nervous system (CNS) depression can lead to suppression of respiratory function.
Rationale 4: Nutritional status is important with older adult patients but is not the primary concern.
Global Rationale: Older adults are at risk for cumulative effects of barbiturates due to diminished hepatic and renal function. Central nervous system (CNS) depression can lead to suppression of respiratory function. Nutritional status is important with older adults but is not the primary concern. Fluid intake is often decreased in older adults but is not a side effect of barbiturates. Barbiturates do not affect electrolyte balance.

Answer to Question 2

1,5
Rationale 1: The myocardium receives blood from the right and left coronary arteries that arise from aortic sinuses at the base of the aorta.
Rationale 2: The coronary veins, not arteries, carry blood to the right atrium.
Rationale 3: Although the heart is filled with blood, this is not its source of oxygen.
Rationale 4: The coronary arteries supply blood to all areas of the heart, not primarily the left ventricle.
Rationale 5: The right and left coronary arteries diverge into smaller branches that encircle the heart.
Global Rationale: The myocardium receives blood from the right and left coronary arteries that arise from aortic sinuses at the base of the aorta. These diverge into smaller branches that encircle the heart. The coronary veins, not arteries, carry blood to the right atrium. The coronary arteries supply blood to all areas of the heart, not primarily the left ventricle. Although the heart is filled with blood, this is not its source of oxygen.
