NREMT: AEMT Level › Cardiac Assessment and Monitoring
A 69-year-old female with CHF reports worsening dyspnea and cannot lie flat. She has pitting edema and a productive cough with pink frothy sputum. She is anxious and tachypneic. Lung sounds reveal diffuse crackles. Initial vitals: HR 116, BP 172/104, RR 36, SpO₂ 80% on room air. ECG shows sinus tachycardia. You apply ECG monitoring and sit her upright. What is the next step in managing this patient's care?
Apply CPAP and titrate oxygen while reassessing mental status and blood pressure frequently
Treat for asthma with bronchodilator only and discontinue cardiac monitoring
Administer nitroglycerin only after giving a 1-liter fluid bolus to prevent hypotension
Delay respiratory support until arrival because oxygen saturation may improve spontaneously
Explanation
This question tests AEMT-level skills in cardiac assessment and monitoring, specifically the ability to interpret clinical findings and apply appropriate interventions. Understanding cardiac symptoms and vital signs is crucial for diagnosing conditions such as myocardial infarction or heart failure. In this scenario, the patient's symptoms and ECG findings indicate acute decompensated heart failure with pulmonary edema, requiring CPAP for respiratory support. Choice A is correct because it accurately addresses the patient's condition by improving oxygenation and monitoring vital signs. Choice B is incorrect because it overlooks key symptoms indicating hypertension, where fluids could worsen the condition. To assist students, emphasize the importance of recognizing cardiac signs and tailoring interventions to specific conditions. Practice scenarios where students identify symptoms and choose interventions within AEMT scope.
A 72-year-old male with CHF presents with worsening dyspnea and orthopnea over two days. He reports needing three pillows to sleep and notes increased leg swelling. On exam he is tachypneic with accessory muscle use and can only speak 2–3 words at a time. Lung sounds reveal diffuse crackles; mild cyanosis is present around the lips. JVD is visible; pitting edema 3+ at ankles. Initial vitals: HR 104, BP 188/110, RR 32, SpO₂ 84% on room air. ECG shows sinus tachycardia. You apply ECG monitoring and prepare airway equipment.

A 70-year-old female with long-standing HTN and prior MI calls for worsening shortness of breath. She reports orthopnea, sleeping upright in a chair, and waking at night gasping for air. She notes bilateral ankle swelling and a 6-lb weight gain this week. On exam she is tachypneic with accessory muscle use; skin is warm, mildly diaphoretic. Lung auscultation reveals bilateral crackles halfway up; mild wheezing is present. Jugular venous distention is noted at 45°. Pitting edema 2+ to mid-shin. Initial vitals: HR 110, BP 176/102, RR 30, SpO₂ 88% on room air. ECG shows sinus tachycardia without ST elevation. You place her on continuous ECG and pulse oximetry. Which intervention is most appropriate for the patient's condition?
Administer a large normal saline bolus to treat presumed dehydration and tachycardia
Treat as anxiety-related dyspnea and coach slow breathing without monitoring
Withhold respiratory support and observe for improvement during transport only
Apply CPAP and titrate oxygen to improve SpO₂ while monitoring blood pressure
Explanation
This question tests AEMT-level skills in cardiac assessment and monitoring, specifically the ability to interpret clinical findings and apply appropriate interventions. Understanding cardiac symptoms and vital signs is crucial for diagnosing conditions such as myocardial infarction or heart failure. In this scenario, the patient's symptoms and ECG findings indicate acute decompensated heart failure with pulmonary edema, requiring non-invasive positive pressure ventilation to improve oxygenation. Choice A is correct because it accurately addresses the patient's condition by using CPAP to reduce work of breathing and enhance gas exchange while monitoring for hemodynamic changes. Choice B is incorrect because it overlooks key symptoms indicating fluid overload rather than dehydration, which could worsen pulmonary edema. To assist students, emphasize the importance of recognizing cardiac signs and tailoring interventions to specific conditions. Practice scenarios where students identify symptoms and choose interventions within AEMT scope.
A 71-year-old male with CHF presents with dyspnea and orthopnea. He reports sleeping upright and has increasing leg swelling. On exam he is tachypneic; lung sounds reveal crackles at the bases. JVD is present; pitting edema 2+. Initial vitals: HR 102, BP 184/108, RR 28, SpO₂ 90% on room air. ECG shows sinus tachycardia. Continuous ECG monitoring is in place. Based on the scenario, what is the most likely cardiac condition?
Atrial fibrillation causing irregularly irregular tachycardia without crackles or edema
Acute decompensated congestive heart failure causing pulmonary congestion and peripheral edema
Inferior STEMI causing ST elevation and hypotension with clear lung sounds
Cardiogenic shock causing severe hypotension, bradycardia, and altered mental status
Explanation
This question tests AEMT-level skills in cardiac assessment and monitoring, specifically the ability to interpret clinical findings and apply appropriate interventions. Understanding cardiac symptoms and vital signs is crucial for diagnosing conditions such as myocardial infarction or heart failure. In this scenario, the patient's symptoms and ECG findings indicate acute decompensated congestive heart failure, requiring ventilatory support and preload reduction. Choice A is correct because it accurately addresses the patient's condition by recognizing pulmonary congestion and edema. Choice B is incorrect because it overlooks key symptoms indicating crackles and hypertension, not consistent with inferior STEMI's clear lungs.
