Pharmacology #1
This medication used for severe hypoglycemia in an adult may be administered intramuscularly in a dose of 1 mg when IV access is unavailable.
What is glucagon?
This medication treats carbon monoxide poisoning by increasing the amount of oxygen dissolved in plasma under pressure.
What is hyperbaric oxygen therapy?
This ECG interval represents the time required for ventricular depolarization and repolarization.
What is the QT interval?
This type of burn is characterized by blister formation and damage extending into the dermis.
What is a partial-thickness burn?
This cognitive error occurs when a provider's recent experience with a diagnosis makes them more likely to diagnose it again.
What is availability bias?
This medication for symptomatic calcium channel blocker overdose may be administered as an initial dose of 1–3 grams IV in adults.
What is calcium chloride?
This antiarrhythmic suppresses ventricular dysrhythmias by blocking fast sodium channels and shortening the action potential duration.
What is lidocaine?
This chamber of the heart receives oxygenated blood directly from the pulmonary veins.
What is the left atrium?
This trauma finding consists of bruising over the mastoid process and may indicate a basilar skull fracture.
What is Battle's sign?
This respiratory pattern of progressively deeper respirations followed by apnea is commonly associated with severe neurologic injury.
What is Cheyne-Stokes respirations?
This medication used in severe asthma exacerbations may be administered subcutaneously at a dose of 0.3 mg of a 1:1,000 concentration.
What is epinephrine?
This medication used for severe preeclampsia and eclampsia decreases acetylcholine release at the neuromuscular junction and may produce loss of deep tendon reflexes when toxic.
What is magnesium sulfate?
This artery most commonly supplies blood flow to the AV node in a right-dominant circulation.
What is the right coronary artery?
This abdominal organ is the most commonly injured solid organ in blunt trauma.
What is the spleen?
This diagnosis should be strongly considered in an elderly patient with atrial fibrillation who develops sudden, severe abdominal pain that seems out of proportion to the physical examination.
What is mesenteric ischemia?
This medication for organophosphate poisoning may require repeated doses far exceeding those normally used for bradycardia.
What is atropine?
This vasopressor can cause significant tissue necrosis if extravasation occurs during administration.
What is norepinephrine?
This type of shock is characterized by elevated systemic vascular resistance and reduced cardiac output due to pump failure.
What is cardiogenic shock?
This fracture of the cervical spine is commonly associated with axial loading injuries such as diving accidents.
What is a Jefferson fracture?
This response is appropriate when encountering a patient with bedbugs.
What is freak all the way out?
This medication for status epilepticus has a pediatric loading dose of 20 mg/kg IV and is increasingly used as a second-line anticonvulsant.
What is levetiracetam (Keppra)?
This antidote for acetaminophen overdose replenishes glutathione stores in the liver.
What is N-acetylcysteine?
This ECG finding describes an R wave in V1 that is taller than the S wave and may suggest a posterior myocardial infarction.
What is dominant R-wave progression in V1?
This spinal cord syndrome results from damage to the anterior two-thirds of the cord and causes loss of motor function and pain sensation while often preserving proprioception.
What is anterior cord syndrome?
An intubated trauma patient suddenly becomes profoundly hypotensive, develops increasing peak airway pressures, and has absent breath sounds on the left side.
What is a tension pneumothorax?
