QUESTIONS AND 100% VERIFIED SOLUTIONS,
ELABORATED & DETAILED CORRECT ANSWERS
# of Lobes in each Lung - CORRECT ANSWER: Right lung- 3, Left lung- 2.
20 Seconds or Less - CORRECT ANSWER: *A single pediatric intubation should not exceed
more than 20 seconds. If intubation cannot be performed at this time, abort the attempt and
resume bag-mask ventilations.
3-3-2 RULE - CORRECT ANSWER: The first 3 refers to mouth opening, ideally a pt's mouth
should open at least 3 fingerwidths (5cm). The second 3 refers to the length of the mandible, at
least 3 fingerwidths is optimal. The 2 part refers to the distance from the hyoid bone to the
thyroid notch; it should be at least 2 fingers wide.
Accessory Muscles - CORRECT ANSWER: Secondary muscles of breathing, and include the
sternocleidomastoid and trapezius muscles of the neck.
Acetylcholine (ACh) - CORRECT ANSWER: Paralytic medications function at the
neromuscular junction and relax the muscle by impeding the action of ACh.
Adventitious Respirations - CORRECT ANSWER: Abnormal airway sounds.
Aerobic Metabolism - CORRECT ANSWER: In the presence of oxygen, the cells convert
glucose into energy through this process.
Alveoli - CORRECT ANSWER: Balloon-like clusters of single-layer air sacs, and serve as the
functional site for the exchange of oxygen and CO2. This exchange occurs by simple diffusion
over the pulmonary capillaries.
, Anaerobic Metabolism - CORRECT ANSWER: Without adequate O2, the cells do not
completely convert glucose into energy and lactic acid and other toxins accumulate into the cell.
If this is not corrected (with adequate perfusion and ventilation) the cells will die.
Apnuestic Breathing - CORRECT ANSWER: Prologned, gasping inhalation followed by
extremely short, ineffective exhalation; associated with brainstem insult.
Asthma - CORRECT ANSWER: *Worst thing with asthma is when you hear absent breath
sounds, that means no air is moving! Wheezing with asthma means that bronchoconstriction is
happening, but at least air is moving.
Bag Valve Mask - CORRECT ANSWER: Whenever possible, you and your partner should work
together to provide ventilation's with the BVM, to ensure the artificial ventilations are adequate,
you must look for CHEST RISE AND FALL, make sure the RATE IS NOT TOO FAST or
SLOW, and make sure the PULSE RATE IMPROVES.
Barbiturates - CORRECT ANSWER: Sedative-hypnotic medications that have a long history of
use. Barbiturates can cause significant respiratory depression and a drop in BP of approx 10% in
normovolemic pt's. The drop in BP can be profound and potentially irreversible in hypovolemic
pt's.
Benzodiazepines - CORRECT ANSWER: Sedative-hypnotic drugs. Diazepam (Valium), and
midazolam (Versed), provide muscle relaxation and mild sedation and are used for anxiety and
antiseizure medications. They also provide anterograde amnesia, which is beneficial for invasive
and uncomfortable procedures; the pt will not likely recall the event. Resp depression and
hypotension are potential side effects.
Beta-2 Adrenergic Receptors - CORRECT ANSWER: Stimulate bronchodilation.
Bronchioles - CORRECT ANSWER: Made of smooth muscle & lined with beta-2 receptors,
which can dilate and constrict based on stimuli.
