A man is unresponsive after overdosing on heroin. He is apneic and his pulse is slow. Which of the following is the most critical intervention?

Bag-mask ventilation

Which of the following techniques should you use to dislodge a foreign body airway obstruction in a patient who is in an advanced stage of pregnancy or who is very obese?

Chest thrusts

Which of the following is considered an obvious sign of death and would not require the initiation of CPR?

Dependent blood pooling

Which of the following injuries or conditions would have the lowest treatment priority during the primary survey?

Impressive amount of dried blood in the hair but no active bleeding

Which of the following statements regarding clinical decision making is correct?

Irrelevant or extraneous data can skew your interpretation of a patient's condition, potentially leading to inappropriate care.

Which of the following maneuvers should be used to open a patient's airway when a spinal injury is suspected?

Jaw-thrust

A 70-year-old male presents with an acute onset of difficulty breathing that woke him from his sleep. He has a history of hypertension, atrial fibrillation, and several heart attacks. During your assessment, you note dried blood around his mouth. The patient tells you that he cannot lie down because he will "smother." What additional assessment findings will you most likely discover?

Pulmonary rales

A 40-year-old female complains of a sudden onset of chest pressure. When assessing the history of her present illness, which of the following patient responses would identify a palliating factor?

Relief of pain when limiting movement or exercise

Which of the following statements most accurately describes asthma?

Reversible obstruction caused by bronchospasm, mucus production, and edema

Most prehospital cardiac arrests occur as the result of:

a cardiac dysrhythmia.

Definitive treatment to reduce acute respiratory distress in a patient with a pleural effusion involves:

a fluid thoracentesis.

Ventricular tachycardia is:

a rapid contraction of the ventricles that does not allow for normal filling of the heart.

Appropriate treatment for a patient with a mild upper airway obstruction includes:

administering oxygen and transporting immediately.

Ascites is defined as:

an accumulation of fluid in the peritoneal space.

If ventilation becomes difficult due to gastric distention, the patient will require:

an orogastric or nasogastric tube

A patient with congenital anisocoria would be expected to have pupils that:

are unequal in size.

A 63-year-old male is being transported to the hospital for an acute exacerbation of his emphysema. He is on oxygen via nasal cannula at 4 L/min. During your reassessment, you note that his mental status has deteriorated and his respirations have become markedly slow and shallow. You should:

assist his ventilations with a bag-mask device.

After establishing that an adult patient is unresponsive and not breathing, you should:

check for a carotid pulse.

A 61-year-old female called EMS after suddenly being awakened in the middle of the night with a feeling that she was "smothering." You arrive to find the patient, very apprehensive and restless, sitting on the living room couch in obvious respiratory distress. Her BP is 160/90 mm Hg, pulse is 110 beats/min and irregular, and respirations are 24 breaths/min and labored. Auscultation of her lungs reveals diffuse rhonchi in all fields. Treatment for this patient should include:

continuous positive airway pressure and an IV line set to keep the vein open.

In a responsive patient, capnography is used to:

determine the amount of carbon dioxide produced by aerobic metabolism.

You arrive at the scene of a motor-vehicle crash where a small car has struck a tree head-on. You see one patient sitting in the driver's seat with the door open. Prior to exiting the ambulance, you should:

don the appropriate protective equipment.

The movement and utilization of oxygen in the body is dependent on all of the following, except:

effective alveolar-capillary osmosis.

During your rapid trauma assessment (rapid body scan) of a man who sustained a gunshot wound to the chest, you note the presence of air under the skin. This clinical finding is referred to as subcutaneous:

emphysema.

is a disease outbreak that occurs on a global scale.

You are dispatched to a shopping mall for a female patient who is "sick." When you arrive, you find the patient, who appears confused, sitting on a bench in the middle of the mall. There is a small amount of blood in her hair. As you introduce yourself to the patient, you should direct your partner to:

manually stabilize her head in a neutral position.

Indicators to the patient that you are actively listening to him or her include:

periodically repeating back important points to the patient.

You are assessing the pupils of a patient who was struck in the back of the head. You note that his pupils differ in size by slightly less than 1 mm. The patient is conscious, alert, and oriented to person, place, time, and event. You should suspect:
