Q4. A nurse is assessing an adult client’s oxygenation status and observes a respiratory rate of 36 with an oxygen saturation of 89 % on room air and mild nasal flaring. The nurse would describe these findings as:

a. Hyperoxygenation

b. Impaired oxygenation in an adult

c. Bradypnea

d. Normal findings in an adult

Answer 1

Q 01 - LUNGS AND ALVEOLI

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Q 02 - ANSWER A ( AREA SARROUNDING THE MOUTH )

The nurse should examine the mouth sarrounding area, along with the conjunctiva and sclera, nailbeds, palms, soles, lips, and tongue to assess for oxygenation in a client with dark skin.

Q 03 - ANSWER C ( PATHOLOGICAL )

The pathological changes in the lungs may cause many of disease like COPD, BRONCHIAL ASTHMA, CHRONIC BRONCHITIS, LUNGS CANCER, COVID-19 etc. And older adult are more susceptible to the disease and they are easy are to infection of disease.

Q 04 - ANSWER B ( IMPAIRED OXYGENATION IN AN ADULT )

It is ventilation without perfusion. Conditions that cause changes or collapse of the alveoli (e.g., atelectasis, pneumonia, pulmonary edema, and acute respiratory distress syndrome) impair ventilation.

Oxygen saturation levels should be between 92% and 98% for an adult without an underlying respiratory condition. Lower than 92% is considered hypoxic. For patients with COPD, oxygen saturation levels may range from 88% to 92%. Lower than 88% is considered hypoxic.
