Question 1

The healthcare provider wants an SvO₂level on a patient with a pulmonary artery catheter. The nurse collects this sample from which port of the catheter?

Accepted Answer

The SvO2 (mixed venous oxygen saturation) level is measured from blood drawn from the distal lumen port of a pulmonary artery catheter, which reflects the oxygen saturation of blood returning to the heart from the body, indicating the balance between oxygen delivery and consumption.

Question 2

A patient is being evaluated for chest pain in the emergency department. Which laboratory test is the best to determine if this patient has experienced an acute myocardial infarction?

Accepted Answer

Troponin is the most specific and sensitive marker for myocardial infarction, making it the best choice for evaluating a patient for an acute myocardial infarction.

Question 3

The nurse correlates damage to which area of the heart in patients who experience an inferior wall myocardial infarction (MI)?

Accepted Answer

A

Question 4

The nurse correlates damage to which area of the heart in the patient who has complete occlusion of the left anterior descending (LAD) artery?

Accepted Answer

The left anterior descending (LAD) artery supplies blood to the anterior wall of the heart, so occlusion of the LAD artery would primarily affect the anterior wall.

Question 5

The nurse provides care to a patient with an arterial line. Which is the priority nursing action when providing care to this patient?

Accepted Answer

Labeling the line "No IV medications" is crucial because arterial lines are not meant for administering medications, and doing so could lead to serious complications.

Question 6

In setting up hemodynamic monitoring equipment, the nurse correlates which action as the rationale for zeroing the transducer?

Accepted Answer

Zeroing the transducer to atmospheric pressure is essential to ensure that the readings reflect the true intravascular pressure without being influenced by external atmospheric pressure. This calibration step offsets any atmospheric pressure that could alter the accuracy of the hemodynamic measurements.

Question 7

The nurse correlates which measurement as an indirect measurement of cardiac contractility?

Accepted Answer

The Left Ventricular Stroke Work Index (LVSWI) is an indirect measurement of cardiac contractility because it assesses the amount of work the left ventricle performs with each contraction, adjusted for body surface area. This provides insight into the heart's efficiency and strength in pumping blood.

Question 8

The nurse recognizes which clinical manifestation in the patient with right-sided heart failure?

Accepted Answer

Increased central venous pressure is a clinical manifestation of right-sided heart failure, as the heart struggles to pump blood effectively to the lungs, leading to a backup of blood in the venous system.

Question 9

The nurse conducts an Allen test for a patient who requires the placement of an arterial line. Which finding indicates a positive test?

Accepted Answer

A positive Allen test is indicated when normal color returns to the hand within 5 to 10 seconds, suggesting adequate collateral circulation.

Question 10

In administering an angiotensin-converting enzyme inhibitor to a patient with cardiomyopathy, the nurse correlates which rationale for this medication?

Accepted Answer

Angiotensin-converting enzyme (ACE) inhibitors are primarily used in patients with cardiomyopathy to reduce afterload. By inhibiting the conversion of angiotensin I to angiotensin II, ACE inhibitors decrease systemic vascular resistance, thereby reducing the pressure against which the heart must pump (afterload). This helps to improve cardiac output and reduce the workload on the heart.

Question 11

The nurse provides instructions to a patient who is being discharged after treatment for a myocardial infarction. Which patient statement indicates a need for additional teaching?

Accepted Answer

Sublingual nitroglycerin is used to treat episodes of angina (chest pain), not as a daily preventative measure. It is taken at the onset of chest pain symptoms, not on a daily routine to prevent them.

Question 12

The nurse instructs a patient recovering from an acute myocardial infarction on the Life's Simple 7 actions. Which patient statement indicates that additional teaching is required?

Accepted Answer

Life's Simple 7 recommends at least 150 minutes of moderate-intensity exercise per week, which is more than walking 30 minutes three times a week.

Question 13

The nurse correlates which arterial blood gas results to compensated metabolic acidosis in the patient with cardiogenic shock?

Accepted Answer

Compensated metabolic acidosis is indicated by a normal pH (7.35-7.45) with decreased bicarbonate (HCO3-) and a compensatory decrease in PaCO2 (indicating respiratory compensation). Choice B shows a normal pH (7.38), decreased HCO3- (20 mEq/L), and decreased PaCO2 (32 mm Hg), which are consistent with compensated metabolic acidosis.

Question 14

The nurse monitors for which hemodynamic parameter in the patient with cardiogenic shock?

Accepted Answer

Cardiogenic shock is characterized by the heart's inability to pump blood effectively, leading to decreased cardiac output. This results in increased afterload as the body attempts to compensate by constricting blood vessels to maintain blood pressure, making it harder for the heart to pump blood.

Question 15

The nurse is preparing to obtain a pulmonary artery occlusive pressure (PAOP) on a patient and implements which action to ensure the patient's safety?

Accepted Answer

Inflating the balloon with 1.5 mL of air is the correct action to ensure the patient's safety when obtaining a PAOP, as overinflation can cause damage to the pulmonary artery.

Question 16

The nurse is caring for a patient experiencing cardiogenic shock. Which medication should the nurse expect to be prescribed to improve this patient's cardiac output?

Accepted Answer

Dobutamine hydrochloride (Dobutamine) is a medication that directly stimulates the heart to increase cardiac output, making it an appropriate choice for treating cardiogenic shock by improving heart function.

Question 17

The nurse is reviewing medications prescribed for a patient with hypertrophic cardiomyopathy. Which medication does the nurse question as a primary treatment for this condition?

Accepted Answer

Digoxin is primarily used for heart failure and atrial fibrillation, not as a first-line treatment for hypertrophic cardiomyopathy. In hypertrophic cardiomyopathy, the main treatment goals are to relieve symptoms and prevent sudden cardiac death, for which beta blockers are commonly used to manage heart rate and contractility. Digoxin, by increasing the force of cardiac contractions, could potentially worsen outflow obstruction in hypertrophic cardiomyopathy.

Question 18

The nurse correlates electrocardiogram (ECG) lead changes in leads II, III, and aVF to which type of myocardial infarction?

Accepted Answer

Leads II, III, and aVF are known as the inferior leads on an electrocardiogram (ECG). Changes in these leads typically indicate an inferior wall myocardial infarction.

Question 19

The nurse is preparing medications for a patient experiencing an acute myocardial infarction. Which medication will dilate the patient's coronary blood vessels?

Accepted Answer

Nitroglycerin is used to dilate blood vessels, including coronary arteries, which can help increase blood flow to the heart muscle during an acute myocardial infarction.

Question 20

The nurse correlates which rationale to the administration of positive inotropic medications to a patient in cardiogenic shock?

Accepted Answer

Positive inotropic medications increase cardiac contractility, which helps the heart pump more effectively, improving cardiac output and tissue perfusion in patients with cardiogenic shock.
