4. what are accessory muscles? name three.
5. when should extreme caution be used while inserting a nasal airway?
6. list the four steps in nasal airway insertion.
7. what is the best suction tip for suctioning infants and children? why

Explanation:

1. Normal respiratory rates vary by age. Adults typically have 12 - 20 breaths per minute, children 20 - 30 breaths per minute, and infants 30 - 60 breaths per minute. These are based on physiological development and oxygen - demand differences.
2. To avoid gastric distention during artificial ventilation, use proper ventilation techniques such as delivering slow, gentle breaths at the appropriate rate, ensuring a good mask - to - face seal without over - pressurizing, and using adjuncts like an oropharyngeal or nasopharyngeal airway to maintain airway patency.
3. Signs of inadequate breathing include rapid or slow respiratory rate, shallow breaths, use of accessory muscles (e.g., sternocleidomastoid, scalene, intercostals), nasal flaring, grunting sounds, and cyanosis (bluish discoloration of skin or mucous membranes).
4. Accessory muscles are muscles that assist the primary respiratory muscles (diaphragm and intercostals) during increased respiratory effort. Three examples are the sternocleidomastoid, scalene, and trapezius muscles.
5. Extreme caution should be used when inserting a nasal airway in patients with facial fractures (especially basilar skull fractures), bleeding disorders, nasal polyps, or severe nasal congestion as it can cause further injury, bleeding, or displacement of foreign bodies.
6. The four steps in nasal airway insertion are: 1) Select an appropriate - sized nasal airway. 2) Lubricate the nasal airway. 3) Insert the airway gently into the larger nostril, following the floor of the nose. 4) Advance the airway until the flange rests against the nostril.
7. The best suction tip for suctioning infants and children is a soft, flexible, and appropriately - sized suction catheter. This is because their airways are more delicate, and a soft tip reduces the risk of mucosal injury, while the appropriate size ensures effective suctioning without causing airway obstruction.

Answer:

1. Adults: 12 - 20 breaths per minute; Children: 20 - 30 breaths per minute; Infants: 30 - 60 breaths per minute.
2. Use proper ventilation techniques like slow, gentle breaths, good mask - seal, and airway adjuncts.
3. Rapid/slow rate, shallow breaths, use of accessory muscles, nasal flaring, grunting, cyanosis.
4. Muscles that assist in breathing. Examples: sternocleidomastoid, scalene, trapezius.
5. In patients with facial fractures, bleeding disorders, nasal polyps, or severe congestion.
6. Select size, lubricate, insert into larger nostril, advance until flange rests.
7. Soft, flexible, appropriately - sized suction catheter due to delicate airways.
