Question 1
A patient with acute decompensated heart failure is receiving dobutamine. Which
assessment finding indicates the medication is having the desired therapeutic
effect?
A. Decreased urine output
B. Increased cardiac output with improved peripheral perfusion
C. Decreased blood pressure
D. Increased pulmonary capillary wedge pressure (PCWP)
,,,answer,,,,: B. Increased cardiac output with improved peripheral perfusion
Rationale: Dobutamine is a beta-1 adrenergic agonist that increases cardiac
contractility and stroke volume, leading to increased cardiac output and improved
tissue perfusion. The desired effect is improved peripheral perfusion (warm, pink
extremities, adequate urine output) and hemodynamic improvement (increased
cardiac output, decreased PCWP). Decreased urine output and decreased blood
pressure would indicate inadequate response or adverse effects.
Question 2
A patient with an acute myocardial infarction (AMI) develops a new systolic
,murmur heard best at the apex, along with hypotension and pulmonary edema.
These findings are most consistent with which complication?
A. Ventricular septal rupture
B. Papillary muscle rupture
C. Left ventricular free wall rupture
D. Pericarditis
,,,answer,,,,: B. Papillary muscle rupture
Rationale: Acute papillary muscle rupture is a life-threatening complication of
myocardial infarction that causes acute mitral regurgitation. The murmur is heard
best at the apex and radiates to the axilla (holosystolic murmur). The abrupt onset
of severe mitral regurgitation causes acute pulmonary edema and cardiogenic
shock. Ventricular septal rupture causes a harsh holosystolic murmur heard best at
the left lower sternal border.
Question 3
A patient is 2 days post-cardiac catheterization via the femoral approach. The
medical assistant notes a 2-cm pulsatile mass with a bruit in the right groin. What is
the most appropriate initial nursing action?
A. Apply a warm compress to the area
B. Apply firm manual pressure above the site
C. Notify the healthcare provider immediately
D. Continue to monitor the site
,,,answer,,,,: C. Notify the healthcare provider immediately
Rationale: This patient has developed a femoral artery pseudoaneurysm,
characterized by a pulsatile mass with a bruit. This is a serious complication
,requiring immediate notification of the healthcare provider. The provider will likely
order a duplex ultrasound to confirm the diagnosis and determine the need for
ultrasound-guided compression, thrombin injection, or surgical repair.
Question 4
A patient with a history of heart failure is prescribed digoxin. Which laboratory value
should be monitored closely due to the risk of digoxin toxicity?
A. Sodium
B. Potassium
C. Magnesium
D. Calcium
,,,answer,,,,: B. Potassium
Rationale: Digoxin toxicity is more likely to occur in patients with hypokalemia, as
low serum potassium increases the binding of digoxin to cardiac sodium-
potassium ATPase pumps. Therapeutic digoxin level is 0.8-2.0 ng/mL. Signs of
toxicity include nausea, vomiting, visual disturbances (yellow-green halos), and
cardiac arrhythmias (bradycardia, heart block, ventricular tachycardia).
Question 5
A patient is being evaluated for Takotsubo cardiomyopathy (stress-induced
cardiomyopathy). Which of the following clinical features would be most
consistent with this diagnosis?
A. ST-segment elevation in multiple coronary distributions on ECG
B. Presence of significant coronary artery obstruction on angiography
, C. Decreased left ventricular ejection fraction with apical ballooning
D. History of typical angina with exercise
,,,answer,,,,: C. Decreased left ventricular ejection fraction with apical
ballooning
Rationale: Takotsubo cardiomyopathy is a transient left ventricular dysfunction
triggered by emotional or physical stress. The hallmark is apical ballooning with
basal hyperkinesis on echocardiography or ventriculography, with the left ventricle
resembling a Japanese takotsubo pot. Coronary angiography typically shows no
significant obstructive coronary artery disease . Patients present with chest pain,
ECG changes, and elevated cardiac biomarkers mimicking acute coronary
syndrome.
Question 6
A patient with a history of hypertension presents with a sudden, severe chest or
back pain described as "ripping" or "tearing." The pain is worst at onset and does
not change with position. Which diagnosis should be suspected?
A. Pulmonary embolism
B. Acute coronary syndrome
C. Aortic dissection
D. Pericarditis
,,,answer,,,,: C. Aortic dissection
Rationale: Aortic dissection is a life-threatening emergency characterized by
sudden, severe, "ripping" or "tearing" chest or back pain. The pain is typically
maximal at onset. It is often associated with a history of hypertension and may
involve the ascending aorta (Stanford Type A) or descending aorta (Stanford Type
