EMR Patient Treatment & Transport practice questions

Correct answer: B. 15 liters per minute

A bag-valve mask with a reservoir is run at 15 liters per minute and delivers close to 100 percent. Running a device outside its intended range either wastes oxygen or fails to deliver the concentration you intended.

• A. That flow rate belongs to a simple face mask.
• B. This flow rate delivers close to 100 percent through a bag-valve mask with a reservoir.
• C. That flow rate belongs to a venturi mask.
• D. That range suits a nasal cannula, far below what keeps a reservoir filled.

Correct answer: C. respiratory depression from suspected opioid toxicity

Naloxone is an opioid antagonist given for respiratory depression from suspected opioid toxicity. Matching each drug to the single problem it is designed to correct is what keeps administration deliberate rather than reflexive. Local protocol governs when and whether you may give it.

• A. That is the indication for oxygen, which is a therapeutic gas.
• B. That is the indication for nitroglycerin, which is a nitrate vasodilator.
• C. This is the indication naloxone is given for; it acts as an opioid antagonist.
• D. That is the indication for activated charcoal, which is an adsorbent.

Correct answer: A. 4 to 12 liters per minute

A venturi mask is run at 4 to 12 liters per minute and delivers a precisely controlled 24 to 60 percent. Running a device outside its intended range either wastes oxygen or fails to deliver the concentration you intended.

• A. This flow rate delivers a precisely controlled 24 to 60 percent through a venturi mask.
• B. That flow rate belongs to a nasal cannula.
• C. That flow rate belongs to a non-rebreather mask.
• D. That flow rate belongs to a bag-valve mask with a reservoir.

Correct answer: C. 6 to 10 liters per minute

A simple face mask is run at 6 to 10 liters per minute and delivers roughly 35 to 60 percent. Running a device outside its intended range either wastes oxygen or fails to deliver the concentration you intended.

• A. That flow rate belongs to a non-rebreather mask.
• B. That flow rate belongs to a nasal cannula.
• C. This flow rate delivers roughly 35 to 60 percent through a simple face mask.
• D. That flow rate belongs to a bag-valve mask with a reservoir.

Correct answer: C. hypoxia or suspected inadequate tissue oxygenation

Oxygen is a therapeutic gas given for hypoxia or suspected inadequate tissue oxygenation. Matching each drug to the single problem it is designed to correct is what keeps administration deliberate rather than reflexive. Local protocol governs when and whether you may give it.

• A. That is the indication for naloxone, which is an opioid antagonist.
• B. That is the indication for activated charcoal, which is an adsorbent.
• C. This is the indication oxygen is given for; it acts as a therapeutic gas.
• D. That is the indication for an epinephrine auto-injector, which is a sympathomimetic.

Correct answer: D. Therapeutic gas

Oxygen is a therapeutic gas. Knowing a drug's class lets you predict its effects and its likely adverse effects even when the specific agent is unfamiliar.

• A. That class describes an epinephrine auto-injector, which is given for anaphylaxis.
• B. That class describes aspirin, which is given for suspected acute coronary syndrome.
• C. That class describes albuterol, which is given for bronchospasm.
• D. Oxygen is a therapeutic gas, which is why it is used for hypoxia or suspected inadequate tissue oxygenation.

Correct answer: D. Intramuscular, mid-outer thigh

An epinephrine auto-injector is administered intramuscular, mid-outer thigh. Route determines onset, and choosing the wrong one can render an otherwise correct drug useless.

• A. That is the route used for activated charcoal rather than for this drug.
• B. That is the route used for aspirin rather than for this drug.
• C. That is the route used for oral glucose rather than for this drug.
• D. An epinephrine auto-injector is given intramuscular, mid-outer thigh, which suits its onset and the situation it treats.

Correct answer: B. Adsorbent

Activated charcoal is an adsorbent. Knowing a drug's class lets you predict its effects and its likely adverse effects even when the specific agent is unfamiliar.

• A. That class describes oxygen, which is given for hypoxia or suspected inadequate tissue oxygenation.
• B. Activated charcoal is an adsorbent, which is why it is used for selected recent oral ingestions when directed by medical control.
• C. That class describes an epinephrine auto-injector, which is given for anaphylaxis.
• D. That class describes aspirin, which is given for suspected acute coronary syndrome.
