1. The nurse is caring for a patient with chronic obstructive pulmonary disease (COPD). The patient has been receiving high-flow oxygen therapy for an extended time. What symptoms should the nurse anticipate if the patient were experiencing oxygen toxicity?
A) Bradycardia and frontal headache
B) Dyspnea and substernal pain
C) Peripheral cyanosis and restlessness
D) Hypotension and tachycardia
Ans: B
Feedback:
Oxygen toxicity can occur when patients receive too high a concentration of oxygen for an extended period. Symptoms of oxygen toxicity include dyspnea, substernal pain, restlessness, fatigue, and progressive respiratory difficulty. Bradycardia, frontal headache, cyanosis, hypotension, and tachycardia are not symptoms of oxygen toxicity.
2. The nurse caring for a patient with an endotracheal tube recognizes several disadvantages of an endotracheal tube. What would the nurse recognize as a disadvantage of endotracheal tubes?
A) Cognition is decreased.
B) Daily arterial blood gases (ABGs) are necessary.
C) Slight tracheal bleeding is anticipated.
D) The cough reflex is depressed.
Ans: D
Feedback:
There are several disadvantages of an endotracheal tube. Disadvantages include suppression of the patient's cough reflex, thickening of secretions, and depressed swallowing reflexes. Ulceration and stricture of the larynx or trachea may develop, but bleeding is not an expected finding. The tube should not influence cognition and daily ABGs are not always required.
