TOPIC 1: CARDIAC ASSESSMENT
10 Questions • 8.6% of Exam • Focuses on the evaluation of cardiac conditions and associated symptoms.
QUESTION 1
Pt has a hx of PE with sudden onset of CP and SOB, what should you do?
Answer: Raise the head of the bed and assess.
Rationale: Sudden chest pain and shortness of breath in a patient with a history of pulmonary embolism (PE) indicate
potential hemodynamic compromise or worsening respiratory status, necessitating immediate assessment and positioning
to optimize ventilation and reduce myocardial workload.
This principle of prioritizing patient assessment and supportive measures aligns with the initial management of acute
respiratory distress.
QUESTION 2
A patient with a spinal curve may have issues lying flat. This is new info what should
you do with a pending surgery.
Answer: Notify the surgical/anesthesia team. Assess the curve. Work with the surgical team on positioning.
Rationale: A spinal curve can significantly alter airway anatomy and respiratory mechanics, necessitating a collaborative
assessment with anesthesia and surgery to determine optimal intraoperative positioning and mitigate risks. This proactive
communication ensures patient safety by addressing potential airway management and ventilation challenges posed by the
deformity.
QUESTION 3
What valvular disorder is associated with pulmonary HTN and hemoptysis?
Answer: Mitral valve stenosis indicative of pulmonary hypertension presenting with fatigue hemoptysis and
SOB.
Rationale: Mitral valve stenosis impedes left atrial outflow, increasing left atrial pressure and subsequently pulmonary
venous pressure, leading to pulmonary hypertension and potential hemoptysis from alveolar capillary rupture. This reflects
the hemodynamic consequences of left-sided valvular obstruction on pulmonary circulation.

QUESTION 4
Arrhythmia associated with mitral stenosis?
Answer: Atrial fibrillation (AFib)
Rationale: Atrial fibrillation is the most common arrhythmia in mitral stenosis due to atrial dilation and increased atrial
pressure, which disrupts normal electrical conduction. This dilation and pressure overload impair the sinoatrial node's
function and create ectopic foci within the atria.
QUESTION 5
Mitral valve stenosis progression s/s?
Answer: Fatigue, hemoptysis, dyspnea, SOB (this is a sign of pulmonary HTN) anxiety, palpitation, can cause
AFIB.
Rationale: Dyspnea, fatigue, and hemoptysis result from increased pulmonary venous pressure and congestion due to
impaired blood flow through the stenotic mitral valve. Palpitations, anxiety, and atrial fibrillation can occur from atrial
enlargement and increased pulmonary hypertension.
QUESTION 6
Bacterial Endocarditis Treatment
Answer: Antibiotic therapy until complete eradication achieved.
Rationale: Bacterial endocarditis requires prolonged antibiotic therapy to ensure complete eradication of the pathogen from
the infected cardiac vegetations. This extended treatment is necessary to prevent recurrent bacteremia and the potential
development of complications such as valvular damage or systemic emboli.
QUESTION 7
Infectious diseases of the heart diagnosis
Answer: Diagnosis is made by patient symptoms and echocardiogram (echos are noninvasive)
Rationale: Infective endocarditis diagnosis relies on clinical manifestations combined with echocardiography, which
visualizes vegetations on heart valves, to confirm the presence and extent of infection
noninvasively. This approach integrates patient presentation with objective imaging findings to establish the diagnosis.
