Which of the following conditions is caused by the body’s immune system attacking its own insulin producing pancreatic cells?
Answer(s): A
Type 1 diabetes is characterized by the body’s immune system attacking its own insulin-producing pancreatic cells. Type 2 diabetes is when the pancreas produces insulin but the body can’t effectively utilize it, and it isn’t an autoimmune disease like Type 1 diabetes. A hyperglycemic crisis can be caused by either Type 1 or Type 2, and a myxedema coma has nothing to do with diabetes.
You arrive on scene to find a patient with an altered mental status. You quickly scan the scene. Which of the following items will help to point you in the right direction in finding a cause of the altered mental status?
Answer(s): B
The scene survey can lead to some very important clues to what might be going on with your patient. Medications for specific medical conditions can lead you in the correct direction. Not only does it give you the patient’s past medical history, but it tells where to start your assessment and investigation of the patient’s signs and symptoms while an unkempt house and smells can tell you about the patient’s lifestyle and ability to care for themselves.
A 2-month-old patient is drowsy following generalized tonic-clonic activity. The baby has no medical history and feels warm to the touch. There is a petechial rash on the baby's trunk and extremities. The vital signs are BP 76/50 mmHg, P 120/min, R 24/min, and SpO2 99% on room air. The temperature is 103.1°F (39.5°C). Is the patient more likely experiencing febrile seizure or meningitis, and why?
Answer(s): C
Simple febrile seizures typically occur in children between 6 months and 5 years of age. A 2-month-old is too young for a simple febrile seizure, making a serious infection such as meningitis more likely.
An infectious disease spread by the fecal-oral route that is considered an acute infection with a currently available vaccine is:
Hepatitis A is transmitted via the fecal-oral route and presents as an acute infection. A vaccine is available and commonly used for prevention.
A patient has facial drooping, left side paralysis, and slurred speech. The vital signs are BP 160/100, P 100, R 20, and SpO2 96% on room air. Which of the following interventions is appropriate for this patient?
Stroke patients with unilateral weakness are at risk of injury to the affected extremity, so protecting the paralyzed arm during transport helps prevent further harm.
When assessing an unresponsive diabetic patient, a finding that is most helpful to differentiate between hyperglycemia and hypoglycemia is:
Hyperglycemia often presents with deep, rapid respirations (Kussmaul breathing) as the body attempts to correct acidosis, whereas hypoglycemia typically does not produce this breathing pattern, making respiratory rate and depth a key differentiator.
A 70-year-old patient has a sudden onset of difficulty breathing with throat and chest tightness after working outside. The EMT auscultates bilateral wheezes. The vital signs are BP 60/44, P 128, R 28, and SpO2 90% on room air. Which of the following treatments should the EMT administer?
The patient shows signs of anaphylaxis with respiratory distress, wheezing, and severe hypotension. Epinephrine is the first-line treatment because it reverses airway constriction and improves blood pressure through vasoconstriction.
Heat exhaustion is most frequently associated with:
Heat exhaustion results from excessive fluid and electrolyte loss through sweating, leading to decreased circulating volume and hypovolemia.
