Question 1

You are performing abdominal thrust on a patient who becomes unresponsive. The very first thing you should do is:

Accepted Answer

activate the emergency response system.

Answer

If a patient receiving abdominal thrusts for a foreign body airway obstruction becomes unresponsive, the very first action is to activate the emergency response system (e.g., call 911/EMS). This is because the patient's condition has worsened significantly, indicating a medical emergency requiring advanced care. After activating EMS, the rescuer should then begin CPR, starting with chest compressions.

Question 2

Gastric inflation can cause all of the following conditions, except:

Accepted Answer

emphysema.

Answer

Gastric inflation, which occurs when air enters the stomach during ventilations, can lead to several complications like aspiration (inhaling stomach contents), vomiting, and even pneumonia if aspiration occurs. However, emphysema is a chronic lung disease characterized by damage to the alveoli, and it is not a direct consequence or condition caused by acute gastric inflation during resuscitation efforts.

Question 3

You are on the scene of a 77-year-old female who is not breathing. This condition is best described as:

Accepted Answer

apnea.

Answer

Apnea is the medical term used to describe the absence of breathing. In the scenario of a 77-year-old female who is not breathing, "apnea" accurately and precisely describes her condition. Other options like anemia (lack of red blood cells), aphasia (difficulty with speech), and anoxia (absence of oxygen) do not describe the cessation of breathing itself.

Question 4

The structure that prevents food or liquid from entering the larynx is called the:

Accepted Answer

epiglottis

Answer

The epiglottis is a leaf-shaped flap of cartilage located at the base of the tongue, which covers the opening of the larynx (voice box) during swallowing. Its primary function is to prevent food or liquid from entering the trachea (windpipe) and lungs, directing it instead into the esophagus. This protective mechanism is crucial for preventing aspiration into the respiratory tract.

Question 5

All of the following are upper airway structures, except the:

Accepted Answer

alveoli

Answer

The upper airway structures include the nasopharynx, oropharynx, larynx, and epiglottis, all of which are involved in conducting air to the lungs. The alveoli, however, are tiny air sacs located deep within the lungs, specifically in the lower respiratory tract. Their primary function is gas exchange, making them a part of the lower airway, not the upper airway.
