Free FP-C Medical Emergencies Questions and Answers — Questions and Answers
Question 1: A 65-year-old patient presents with sudden onset of chest pain, shortness of breath, and diaphoresis. <br>Which of the following conditions is most likely?
- Myocardial infarction (Correct answer)
- Pulmonary embolism
- Tension pneumothorax
- Aortic dissection
Correct answer: Myocardial infarction
The sudden onset of chest pain, shortness of breath, and diaphoresis (sweating) in an older adult are classic and highly concerning symptoms indicative of a myocardial infarction (heart attack). These symptoms arise from a blockage in the coronary arteries, leading to ischemia and damage to the heart muscle.
Question 2: What is the first-line treatment for a patient experiencing status epilepticus in a pre-hospital setting?
- Phenobarbital
- Phenytoin
- Lorazepam (Correct answer)
- Levetiracetam
Correct answer: Lorazepam
Lorazepam, a benzodiazepine, is the first-line treatment for status epilepticus in the pre-hospital setting due to its rapid onset of action and high efficacy in terminating prolonged seizures. It works by enhancing the inhibitory effects of GABA in the brain, thereby suppressing abnormal neuronal activity.
Question 3: A 45-year-old diabetic patient is found unconscious with a blood glucose level of 30 mg/dL. What is the most appropriate initial treatment?
- Administer 1 mg of glucagon intramuscularly
- Administer 50% dextrose intravenously (Correct answer)
- Administer insulin subcutaneously
- Provide oral glucose if the patient regains consciousness
Correct answer: Administer 50% dextrose intravenously
For an unconscious diabetic patient with severe hypoglycemia (blood glucose 30 mg/dL), intravenous 50% dextrose provides an immediate and concentrated source of glucose directly to the bloodstream. This rapidly raises blood sugar levels, reversing the neurological effects of hypoglycemia and restoring brain function.
Question 4: In the case of suspected opioid overdose with respiratory depression, what is the most appropriate initial action?
- Place the patient in a recovery position
- Provide oxygen via nasal cannula
- Start CPR immediately
- Administer naloxone (Correct answer)
Correct answer: Administer naloxone
In cases of suspected opioid overdose with respiratory depression, administering naloxone is the most appropriate initial action. Naloxone is an opioid antagonist that rapidly reverses the life-threatening respiratory depression caused by opioids, restoring spontaneous breathing and preventing further hypoxia and brain injury.
Question 5: A patient presents with confusion, headache, and vomiting after being found in a running car in a closed garage. What is the most likely diagnosis?
- Heatstroke
- Carbon monoxide poisoning (Correct answer)
- Hypoglycemia
- Drug overdose
Correct answer: Carbon monoxide poisoning
The scenario of a running car in a closed garage strongly indicates exposure to carbon monoxide (CO). CO is an odorless, colorless gas produced by incomplete combustion, and its poisoning causes symptoms like confusion, headache, and vomiting by binding to hemoglobin and preventing oxygen transport to tissues.
