A 74-year-old who takes a beta-blocker and has long-standing high blood pressure fell down a flight of stairs. His heart rate is 76, pressure 104/70, and his skin is cool and pale. How should you interpret these findings?
Answer: A. Possible shock, since his medicine blunts the rate and 104 may be low for him
Analyze cues: a beta-blocker prevents the compensatory tachycardia you rely on, and a systolic of 104 in someone whose usual pressure is high can represent a large drop. Cool, pale skin is the cue that betrays hypoperfusion. Neurogenic shock produces warm, dry skin below the injury, and calling the numbers 'normal' ignores both his medication and his baseline.
A patient is actively bleeding after delivery, with a boggy uterus that firms only briefly with massage. Which medication class would a paramedic anticipate as the targeted therapy?
Answer: A. A uterotonic that stimulates the uterus to contract
Atony is a contraction problem, so the drug that fixes it makes the uterus contract; an antifibrinolytic is often added to protect the clot that forms. A beta-agonist relaxes uterine muscle — the opposite of what is needed — and lowering pressure or volume in a bleeding patient worsens the shock that the hemorrhage is already causing.
A motorcyclist has a GCS of 8, an open femur fracture now controlled with a tourniquet, and a systolic of 84. How should the fluid target differ from that of a patient with torso bleeding alone?
Answer: A. Avoid hypotension, aiming for a higher systolic target
With a significant head injury, preventing hypotension outweighs the concern about rebleeding, so fluid is titrated to a higher pressure than the radial-pulse endpoint used for isolated torso bleeding. Withholding fluid is the tempting 'brain swelling' error, but hypotension kills far more head-injured patients than crystalloid does, and waiting for unequal pupils means waiting for herniation.
A football player is sweating heavily, dizzy and nauseated after practice. He is alert and oriented, with a heart rate of 112 and a core temperature of 38.6°C (101.5°F). What is the most appropriate care?
Answer: A. Move to shade, loosen clothing and give oral fluids if he can drink
Generate solutions: normal mental status and a core temperature below the heat-stroke range define heat exhaustion, which responds to rest, cooling measures and oral fluid in an alert patient. Immersion is reserved for heat stroke. An IV is reasonable if he cannot drink, but routine boluses to a target rate are unnecessary, and gear traps heat.
A 3-year-old with fever since this morning is irritable, and her parents point to small purple spots on her legs that do not fade when pressed. They say her doctor called an earlier rash viral. What is the best approach?
Answer: A. Treat it as possible meningococcal sepsis: mask up, check perfusion, move fast
Fever with a non-blanching purple rash is meningococcal disease until proven otherwise; it can progress to shock within hours, so the crew wears a mask for droplet protection, assesses perfusion closely and transports without delay. An earlier diagnosis for a different rash is diagnostic momentum, and waiting to watch the spots spread wastes the time that matters most.
A 58-year-old with a COPD exacerbation was placed on CPAP. Ten minutes later his breathing is easier, but his blood pressure has fallen from 132/80 to 84/52. The most likely cause is:
Answer: A. Positive pressure is reducing venous return
Positive intrathoracic pressure squeezes the great veins and reduces preload, and a patient who is volume-depleted can drop the pressure sharply — lower or remove the CPAP and reassess. A pneumothorax is possible with positive pressure but would bring worsening, not easier, breathing and unilateral findings. Easier breathing rules out the idea that he has progressed to arrest.
A 76-year-old reports vague abdominal pain that seems out of proportion to a soft, minimally tender abdomen. She has atrial fibrillation. The concern this pattern should raise is:
Answer: A. Mesenteric ischemia from an embolus to the gut
Pain out of proportion to the exam in an older patient with atrial fibrillation is the textbook cue for an embolus blocking blood flow to the bowel, which carries high mortality and is time-critical. Constipation and gastritis are common and tempting, but they explain neither the mismatch nor the embolic risk; older adults with abdominal pain deserve a lower threshold for concern.
A woman at 30 weeks was the restrained driver in a moderate-speed crash. She is calm, her heart rate is 104 and her pressure is 108/70. The reason to treat her as possibly in shock is that:
Answer: A. Pregnancy can hide significant blood loss in the mother
Pregnancy expands blood volume, so a mother can lose a large share of it before her pressure falls, and the fetus is often the first to suffer because blood is diverted away from the uterus. A mild tachycardia is expected in pregnancy, so it is not proof of bleeding by itself — but it cannot be used to reassure you either. Belt injury raises abruption risk; it does not guarantee one.
A 22-year-old with asthma could speak only two words at a time. After a bronchodilator treatment her wheezing is louder, she speaks in full sentences and her accessory muscle use has eased. The best interpretation is:
Answer: A. She is improving because more air is now moving
Louder wheezing after treatment usually means airflow has increased through airways that are still narrowed — the sound needs air to be heard. Longer sentences and less accessory work confirm real improvement. Reading the louder wheeze as deterioration is the classic trap; the dangerous direction is a wheeze that fades while speech and alertness decline.
A 38-year-old injected a large amount of her long-acting insulin in a suicide attempt. After IV dextrose she is awake, her glucose is 96 mg/dL and she says she wants to be left alone. What is the most appropriate action?
Answer: A. Keep her in care with repeat glucose checks during transport
Take action: long-acting insulin keeps lowering the glucose for many hours, so a normal reading now will not last, and a patient who has just tried to harm herself cannot simply be released. Honoring the refusal is tempting because she is now alert, but her safety risk and her recurring hypoglycemia both require transport with frequent glucose checks, following your system's procedures for patients at risk of self-harm.
The first crew hands off 'a panic attack' in a 28-year-old on oral contraceptives who is short of breath with clear lungs, a rate of 118 and an oxygen saturation of 91%. Your best reasoning is:
Answer: A. The findings fit a pulmonary embolism, not anxiety
Accepting a label because someone else applied it is diagnostic momentum. Hypoxia is not a feature of panic, and estrogen use, tachycardia and clear lungs point to a pulmonary embolism. Having her rebreathe into a bag in a hypoxic state is dangerous, and clear lungs are expected in PE — they exclude nothing.
A severe asthmatic has received maximal bronchodilator therapy. He is now exhausted, confused and his capnography is climbing. Which finding marks the point at which intubation becomes indicated?
Answer: A. Fatigue and altered mental status despite treatment
Intubating an asthmatic is high risk and reserved for failing ventilation — exhaustion, a falling level of consciousness and rising CO2 despite maximal therapy. Persistent wheeze after one dose means therapy should continue, tachycardia is expected with beta agonists, and a saturation of 93% on oxygen does not by itself indicate ventilatory failure.
A patient has full-thickness burns encircling the chest. As you ventilate with a bag-mask the chest rises less with each breath despite a clear airway. What is the cause?
Answer: A. Stiff burned skin limiting chest wall expansion
Analyze cues: full-thickness burned skin becomes rigid eschar, and when it encircles the chest it acts like a tight band that prevents expansion — a surgical release at the hospital is the fix, so transport priority rises. Airway swelling would impede flow at the airway itself, which is clear. Bronchospasm causes wheezing and prolonged expiration rather than a stiff chest wall.
An 88-year-old on a beta-blocker 'just feels weak.' Her heart rate is 72, respiratory rate 26, temperature 99.3 °F and blood pressure 104/62. Her record shows a usual pressure near 165/90. Which interpretation fits best?
Answer: A. Relative hypotension that suggests early shock
A drop of about 60 mmHg from her baseline is hypotension for her, even though 104 looks normal, and with a fast respiratory rate it points to sepsis or another shock state; the beta-blocker explains the missing tachycardia. Calling it normal or 'well controlled' is the anchoring trap, and blaming the medication ignores the tachypnea and the change from baseline.
After two unsuccessful intubation attempts on a patient in respiratory failure, the saturation is falling through 86% and BVM ventilation is getting harder. The best next action is:
Answer: A. Stop attempts and place a supraglottic airway
Repeated attempts in a desaturating patient waste oxygen reserve, swell the tissues and make the next attempt worse. A supraglottic airway is the rescue device when intubation fails and mask ventilation is becoming difficult. A surgical airway is reserved for the patient who cannot be oxygenated by any of those means — that point has not been reached yet.
