Q1Which of the following ECG leads are correctly correlated with the area of the heart they represent? Select the two answer options which are correct.
Show answer
✓ Correct answer: Lead I - lateral wall of left ventricle
Leads II, III and aVF represent the inferior wall of the left ventricle. Leads V1 and V2 represent the septum. Leads V3 and V4 represent the anterior wall of the left ventricle. Leads I, aVL, V5, and V6 represent the lateral wall of the left ventricle. Lead aVR obtains information from the upper right side of the heart, and is only used for reciprocal changes in 12-lead ECG.
Q2You are evaluating a patient with known heart history who presents with chest pain. Which of the following conditions might mask the signs of a pulmonary embolism on a CT scan and complicate diagnosis?
Show answer
✓ Correct answer: Chronic obstructive pulmonary disease (COPD)
Answer: Chronic obstructive pulmonary disease (COPD) COPD can cause changes in the pulmonary vasculature and airways, potentially obscuring signs of a pulmonary embolism on imaging studies. It is crucial to consider COPD in patients with a history of smoking or other risk factors. Diabetes, hypertension, and asthma are less likely to interfere with CT findings for pulmonary embolism. While they may present with other complications, they do not typically mask the radiographic appearance of a PE.
Q3Which part of the EKG waveform is primarily influenced by left atrial enlargement?
Show answer
✓ Correct answer: P wave
Answer: P wave Left atrial enlargement can be identified by specific changes in the P wave. It typically leads to a broad, notched P wave in the EKG tracing.
Q4A pregnant woman at 38 weeks gestation presents to the emergency department with a certain medication overdose. Which of the following symptoms are classic signs of magnesium sulfate overdose? Select the three answer options which are correct.
Show answer
✓ Correct answer: Respiratory depression
Magnesium sulfate is often used in obstetric management for conditions like preeclampsia. Overdose of magnesium sulfate can lead to bradycardia, hyporeflexia, and respiratory depression. Tachycardia and seizures are not typical symptoms of magnesium sulfate toxicity.
Q5Using the six-second method to estimate heart rate from an EKG strip, identify the correct heart rate based on the number of QRS complexes. QRS Complexes Heart Rate (bpm) 10 100 8 80 6 60 4 40
Show answer
✓ Correct answer: 10 QRS complexes correspond to a heart rate of 100 bpm
Answer: 10 QRS complexes correspond to a heart rate of 100 bpm. To use the six-second strip method, count the number of QRS complexes within a 6-second interval and multiply that number by 10 to calculate the heart rate in beats per minute (bpm). For example, if there are 10 QRS complexes in six seconds: $$10 \times 10 = 100$$ bpm.
Q6Which type of traumatic injury does not primarily require large-volume intravenous fluid replacement in the pre-hospital setting?
Show answer
✓ Correct answer: head trauma with increased intracranial pressure (ICP)
Answer: head trauma with increased intracranial pressure (ICP) Head trauma resulting in increased intracranial pressure does not typically require aggressive fluid resuscitation. In fact, excessive fluid administration could worsen cerebral edema, leading to more rapid deterioration. Burn injuries, spinal injuries with neurogenic shock, and severe dehydration all require the administration of large amounts of IV fluids to stabilize the patient and correct hypovolemia.
Q7If the sinoatrial node and the AV node both fail to initiate an impulse, the Purkinje fibers take over as the heart's pacemaker. How will this appear on the EKG strip?
Show answer
✓ Correct answer: There are wide and bizarre QRS complexes
Answer: There are wide and bizarre QRS complexes The Purkinje fibers initiating the impulse results in a ventricular rhythm. This leads to wide and bizarre QRS complexes on the EKG, as the impulse is not following the usual pathway through the AV node and Bundle of His.
Q8Which characteristic of the cardiac cells allows them to respond to electrical impulses?
Show answer
✓ Correct answer: Excitability
Answer: Excitability Excitability is the cell's ability to respond to electrical impulses by depolarization. Automaticity is the cell's ability to create impulses without any outside stimulation. Contractility is the ability to contract the cardiac muscle. Conductivity is the ability to pass electrical impulses along neighboring cells.
Q9Identify the key characteristic of ventricular fibrillation as observed in an EKG reading.
Show answer
✓ Correct answer: Chaotic and disorganized ventricular activity
Ventricular fibrillation is typified by disorganized electrical activity in the ventricles leading to chaotic and erratic EKG patterns. The heart's pumping action becomes ineffective, which is a life-threatening medical emergency.
Q10Which of the following is a beta blocker medication for the treatment of an adult patient with acute myocardial infarction (AMI), particularly for reducing myocardial oxygen demand?
Show answer
✓ Correct answer: Metoprolol
Answer: Metoprolol Metoprolol is a beta-blocker (class II) often used in the treatment of acute myocardial infarction (AMI) for reducing myocardial oxygen demand by decreasing heart rate and contractility. This helps in reducing the overall workload on the heart. Aspirin is an antiplatelet agent and is used to prevent further clot formation but is not a beta-blocker. Nitroglycerin is a nitrate used for vasodilation to relieve chest pain, not a beta-blocker. Atropine is an anticholinergic used to treat bradycardia, not a beta-blocker.
