A 22-year-old patient is pale, cool, and diaphoretic after a motor vehicle collision. Vital signs are BP 118/76, HR 112, RR 24. What stage of shock is the patient MOST likely experiencing?
Compensated Shock
A patient presents with crackles, dyspnea, and pink frothy sputum. Which side of the heart is most likely failing?
Left Ventricle
Which disease process is characterized by destruction of alveolar walls and reduced surface area for gas exchange
Emphysema
When administered during a suspected myocardial infarction, aspirin primarily works by
Inhibiting Platelet Aggregation
According to AHA BLS guidelines, the recommended compression depth for an adult is?
At least 2 inches, but no more than 2.4 inches
A 68-year-old patient presents with crushing chest pain, BP 80/50, HR 120, and crackles in both lungs. Which type of shock is MOST likely?
Cardiogenic Shock
In the early stages of cardiogenic shock, the body attempts to maintain blood pressure through
Tachycardia and vasoconstriction
A patient with severe bronchospasm is moving very little air despite receiving oxygen. What is the PRIMARY physiologic problem
Poor Ventilation
Nitroglycerin relieves chest pain primarily by
During adult cardiac arrest management, pulse checks should be limited to
A patient with suspected septic shock presents with warm, flushed skin, a heart rate of 118/min, and a blood pressure of 96/60 mmHg. Which finding best explains the patient's low blood pressure?
Widespread vasodilation causing relative hypovolemia
A patient has a heart rate of 100 bpm and a stroke volume of 70 mL. What is the cardiac output?
7L/min
Albuterol improves breathing primarily by
Relaxing bronchial smooth muscle
What are the 5 rights of medication administration?
Patient, medication, route, dose, time
What is the AHA compression fraction goal?
80%
How do you calculate a shock index?
HR/Systolic BP
Which intervention would MOST increase myocardial oxygen demand
Increasing heart rate and contractility
An asthma patient initially presents anxious and tachypneic. Thirty minutes later, respiratory effort decreases, the patient appears exhausted, and respiratory rate drops from 36/min to 12/min. What is the MOST likely explanation
Impending Respiratory Failure
Which medication directly addresses the life-threatening vasodilation and bronchoconstriction associated with anaphylactic shock
Epi
Which team member is primarily responsible for monitoring CPR quality and identifying areas needing improvement during a resuscitation?
Team leader
A loss of sympathetic nervous system tone causing peripheral vasodilation and unopposed parasympathetic activity
Neurogenic shock
A patient presents with wheezing, orthopnea, crackles, and lower extremity edema. What is the MOST likely cause of the wheezing?
Left sided heart failure-Pulmonary edema
occurs when the amount of air reaching the alveoli does not match the amount of blood reaching the alveoli for gas exchange
V/Q Mismatch
Epi and Norepi act on what receptors in the body?
A1, B1, B2
A1, B1
During a resuscitation, the patient's ETCO₂ suddenly rises from 12 mmHg to 38 mmHg. This most likely indicates?
ROSC
