Crartiboonnalme ofonroxthideenduerstec’stoarcstiaorne?required by law in the home. Carbon monoxide tightly binds to hemoglobin, causing hypoxia. b. Carbon monoxide signals the cerebral cortex to cease ventilations. Carbon monoxide combines with oxygen in the body and produces a c. deadly toxin. 9.

Keep the air entrainment ports clean and unobstructed. c. Give a high enough flow rate to keep the bag from collapsing. d. Drain moisture condensation from the corrugated tubing 2.

Schedule the procedure 1 hour after the patient eats. b. Maintain the patient in the lateral position for 20 minutes. c. Give the prescribed albuterol (Ventolin HFA) before the therapy. d.

Limit exercise to activities of daily living (ADLs). d. Walk 15 to 20 minutes a day at least 3 times/week. 5 3. A patient with severe chronic obstructive pulmonary disease (COPD) tells the nurse, “I wish I were dead! I’m just a burden on everybody.” Based on this information, which nursing diagnosis is most appropriate? a. Complicated grieving related to expectation of death b. Chronic low self-esteem related to physical dependence c. Ineffective coping related to unknown outcome of illness d. Deficient knowledge related to lack of education about 4.

Have the patient rest in bed with the head elevated to 15 to 20 degrees. b. Encourage the patient to sit up at the bedside in a chair and lean forward. c. Ask the patient to rest in bed in a high-Fowler’s position with the knees flexed. d. Place the patient in the Trendelenburg position with pillows behind the head. A 55-yr-old patient with increasing dyspnea is being evaluated for a possible diagnosis of chronic obstructive pulmonary disease (COPD).
