A 44-year-old patient is unresponsive, and an EMT checks for a pulse prior to applying an AED. Which of the following shockable rhythms, ventricular fibrillation or ventricular tachycardia, if either, may still produce a pulse in this patient?
Answer(s): B
Ventricular tachycardia can sometimes produce a pulse if cardiac output is maintained, whereas ventricular fibrillation does not produce any effective cardiac output and therefore has no pulse.
A patient who is 30 weeks pregnant is in cardiac arrest after being hit by a car. How should the EMT proceed? (Choose two.)
Answer(s): A,E
Left uterine displacement relieves pressure on the inferior vena cava to improve circulation during resuscitation, and standard compression depth is maintained to ensure adequate perfusion during CPR.
An 80-year-old female who has diabetes complains of generalized weakness, nausea, vomiting, and fatigue that began 1 hour ago. She has equal hand grasp and her face is symmetrical. Her blood glucose level is 130 mg/dL. What is the most likely cause of her symptoms?
In older patients, myocardial infarction often presents with atypical symptoms such as generalized weakness, nausea, vomiting, and fatigue rather than classic chest pain, especially with a normal glucose level ruling out hypoglycemia.
Which of the following is associated with neurogenic shock?
Answer(s): D
Neurogenic shock results from loss of sympathetic tone, causing widespread peripheral vasodilation and resulting hypotension.
An 86-year-old patient is found unresponsive in the snow. The patient was reported missing the night before from an assisted living facility. How long should the EMT assess the patient's pulse?
In cases of suspected hypothermia, pulse checks should be performed for up to 60 seconds because severe bradycardia can make pulses difficult to detect.
Which of the following findings are consistent with congestive heart failure? (Choose two.)
Answer(s): B,E
Congestive heart failure leads to fluid accumulation in the lungs causing crackles, and fluid retention in the extremities resulting in dependent edema.
A 60-year-old patient has crushing, midsternal chest pain that began about 5 minutes ago with exercise. The patient has no prescription medications. The vital signs are BP 142/102 mmHg, P 90/min, R 16/min, and SpO2 95% on room air. What treatments should the EMT provide? (Choose two.)
Answer(s): A,D
The patient is experiencing acute coronary syndrome. Aspirin should be administered to reduce platelet aggregation, and nitroglycerin can be given to relieve chest pain by improving coronary blood flow.
A 68-year-old patient is anxious with shortness of breath and crackles in their basal lungs. The patient’s skin is pale and clammy. The vital signs are BP 180/100, P 100, and R 22 and shallow. Which of the following positions would be the most appropriate for transport?
Sitting upright in Fowler position improves lung expansion, reduces venous return to the heart, and helps relieve pulmonary congestion in patients with signs of pulmonary edema.
