Out of the following choices, which depicts a patient who is breathing adequately?
Answer(s): A
A regular respiratory rate and equal chest rise are signs of sufficient breathing patterns. Shallow respirations, cyanosis and unusually fast or slow breathing, are all signs of inadequate breathing.
You have been dispatched to the local incarceration facility. You now have a patient who was found unresponsive in her jail cell. Her airway is clear, but her respirations are rapid and slow. The pulse oximeter (SaO2) reads 90%. What should your primary action be?
Answer(s): C
This patient is breathing inadequately, and has a low pulse oximeter and a decreased LOC; therefore, she requires artificial ventilations. These ventilations should be administered before assessing her blood glucose levels, her blood pressure or before initiating her transport.
The patient you are caring for is a child. He is having spontaneous respirations. What does this mean?
Answer(s): D
When your patient is taking unassisted breaths, this is also known as spontaneous breaths. Spontaneous breaths may occur at any rate or tidal volume and with or without difficulty.
CPAP, also known as continuous positive airway pressure, can reduce a patient’s respiratory distress by:
CPAP aids in keeping the alveoli open. It is also a treatment for sleep apnea and can also help to avoid intubation. CPAP does not relieve FBAO.
Why is carbon monoxide exposure dangerous?
Carbon monoxide binds with hemoglobin, more easily than with oxygen. This process prevents sufficient delivery of oxygen to the body.
Which is the primary intervention that should be performed when you are faced with an unresponsive patient with a suspected spinal cord injury?
When you are faced with a patient who has a suspected spinal injury, the head-tilt, chin-lift is contraindicated. The jaw thrust maneuver is an example of an airway technique that should be performed before inserting a mechanical airway adjunct.
Which symptom would indicate partial obstruction of the upper airway?
Stridor occurs in the upper airway. Rales, rhonchi and wheezes all occur in the lower airway.
