From where does the left side of the human heart receive oxygenated blood?
Answer(s): A
The pulmonary veins are the source of oxygenated blood to the left side of the heart. The right side of the heart receives deoxygenated blood from the venae cavae. Deoxygenated blood exits the right heart by way of the pulmonary arteries.
Your patient is in respiratory distress. His medical history shows that he has had multiple myocardial infarctions. His lung sounds show signs of pulmonary edema. You make a note that your patient does not have any JVD or pedal edema. What is your patient most likely experiencing?
Answer(s): C
Pedal enema and JVD are usually indications of right heart failure. Pulmonary edema is usually an indication of left heart failure. The patient’s signs and symptoms are not consistent with angina or asthma.
An EMT cannot find a pulse on a responsive patient. Which of the following should the EMT do next?
A responsive patient is, by definition, conscious and has adequate perfusion. Failure to palpate a pulse in this situation is likely due to assessment error, so the EMT should continue the primary assessment and reassess rather than initiating cardiac arrest interventions.
A patient is having a stroke. Which of the following details are most important to report to the receiving hospital? (Choose two.)
Answer(s): D
The exact time of onset of stroke symptoms is critical because it determines eligibility for time-sensitive treatments such as thrombolytics.
A 67-year-old patient reports crushing chest pressure. The vital signs are BP 156/98, P 64, R 14, and SpO2 94%. What treatments should the EMT provide first? (Choose two.)
Answer(s): A,E
Crushing chest pressure suggests acute coronary syndrome. Early administration of aspirin helps inhibit platelet aggregation, and assisting with nitroglycerin helps relieve myocardial ischemia by improving coronary blood flow.
An unresponsive 79-year-old female has agonal respirations. You should:
Agonal respirations are not adequate breathing and may occur in cardiac arrest. The next step is to assess for a pulse to determine if cardiac arrest is present and guide immediate treatment.
Which of the following pathophysiological responses causes a patient with neurogenic shock to become hypotensive?
Neurogenic shock occurs when disruption of the sympathetic nervous system leads to loss of vascular tone, causing widespread vasodilation and hypotension.
You have achieved ROSC in a 77-year-old female. She remains unresponsive and her vital signs are BP 94/58, P 82, and R 18. In what position should she be placed?
Answer(s): B
An unresponsive patient with a pulse should be placed in the recovery position to help maintain a clear airway and reduce the risk of aspiration.
