1. Signs of impaired breathing in infants and children include all of the following except:

A) nasal flaring.
B) grunting.
C) seesaw breathing.
D) quivering lips.



2. Which of the following observations is most important when assessing a client - s breathing?

A) presence of breathing and pulse rate
B) breathing pattern and adequacy of breathing
C) presence of breathing and adequacy of breathing
D) patient position and adequacy of breathing



3. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min per nasal cannula.The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?

A) COPD clients are stimulated to breathe by hypoxia.
B) COPD clients depend on a low carbon dioxide level.
C) COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
D) COPD clients thrive on a high oxygen level.



4. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO263mmHg, HCO3 23, and oxygenation saturation ( SaO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

A) tuberculosis (TB)
B) pneumonia
C) pleural effusion
D) hypoxia



5. The nurse is teaching a client about erythema infectiosum. Which of the following factors are not correct?

A) There is no rash.
B) The disorder is uncommon in adults.
C) There is no fever.
D) There is sometimes a 'slapped face' appearance.



1. Right Answer: D
Explanation: Lip quivering is a distracter. Signs of impaired breathing in infants and children include all the other options. Physiological Adaptation

2. Right Answer: C
Explanation: It is not enough to simply make sure the client is breathing. The client must be breathing adequately. Physiological Adaptation

3. Right Answer: A
Explanation: COPD clients are compensating for low oxygen and high carbon dioxide levels. Hypoxia is the main stimulus to breathe in persons with chronic hypercapnia.Increasing the level of oxygen decreases the stimulus to breathe. Physiological Adaptation

4. Right Answer: D
Explanation: A combined low PO2 and lowSaO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion.Depending on the degree of the pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation. Physiological Adaptation

5. Right Answer: B
Explanation: Fifths disease, erythema infectiosum, is uncommon in adults. All the other statements are correct. Safety and Infection Control
