Subsection 1: Respiratory Physiology and Assessment
Question 1
A nurse is assessing a child's respiratory pattern and notes that the heart rate increases during
inspiration and decreases during expiration. Which of the following best describes this finding?
A) Cheyne-Stokes respiration
B) Kussmaul respiration
C) Sinus dysrhythmia
D) Biot's respiration
Answer: C) Sinus dysrhythmia
Explanation: Sinus dysrhythmia is a normal physiological variation in children characterized by
an irregular heartbeat that accelerates with inspiration and decelerates with expiration. This
pattern is associated with vagal tone variations and is considered benign in pediatric populations.
Question 2
During a physical assessment, a student nurse prepares to palpate the carotid pulses on a patient.
Which action should the nurse avoid to prevent potential complications?
A) Palpating one carotid artery at a time
B) Assessing the carotid pulse for no more than 5-10 seconds
C) Palpating both carotid arteries simultaneously
D) Using light pressure during palpation
Answer: C) Palpating both carotid arteries simultaneously
Explanation: Simultaneous carotid pulse palpation is contraindicated because excessive
pressure on both carotid sinuses can occlude cerebral blood flow, potentially leading to cerebral
ischemia, syncope, or a vagal response resulting in bradycardia and hypotension.
,Question 3
A postoperative patient reports experiencing shortness of breath and fatigue during ambulation.
The nurse documents a nursing diagnosis of Activity Intolerance. Which clinical findings
support this diagnosis?
A) Increased appetite and weight gain
B) Abnormal heart rate response to activity and exertional dyspnea
C) Decreased respiratory rate and normal blood pressure
D) Improved exercise tolerance and stable vital signs
Answer: B) Abnormal heart rate response to activity and exertional dyspnea
Explanation: Activity Intolerance is characterized by physiological responses that indicate
insufficient physiological or psychological energy to complete daily activities. Key diagnostic
findings include abnormal heart rate or blood pressure responses to activity, exertional dyspnea,
and patient reports of fatigue or weakness.
Question 4
Which of the following represents the three fundamental processes of respiration?
A) Inhalation, exhalation, and gas exchange
B) Ventilation, diffusion, and perfusion
C) Oxygenation, circulation, and elimination
D) Inspiration, expiration, and respiration
Answer: B) Ventilation, diffusion, and perfusion
Explanation: Respiration comprises three essential processes: ventilation (movement of air into
and out of the lungs), diffusion (exchange of oxygen and carbon dioxide between alveoli and
pulmonary capillaries), and perfusion (blood flow through pulmonary circulation to facilitate gas
exchange).
Question 5
The most significant chemical stimulus for regulating ventilation is:
A) Decreased oxygen levels in arterial blood
B) Increased carbon dioxide levels in arterial blood
C) Decreased blood pH levels
D) Increased bicarbonate concentrations
, Answer: B) Increased carbon dioxide levels in arterial blood
Explanation: Arterial carbon dioxide concentration serves as the primary regulator of
ventilation. Elevated CO₂ levels stimulate the respiratory center in the medulla oblongata to
increase the rate and depth of respirations. While decreased oxygen and altered pH also influence
respiration, CO₂ levels exert the most powerful control mechanism.
Question 6
A client participating in a cardiac rehabilitation program asks the nurse why their breathing rate
increases during exercise. Which physiological response should the nurse explain?
A) The body needs to eliminate excess water through respiration
B) The body requires additional oxygen and needs to eliminate accumulated carbon dioxide
C) Exercise causes bronchodilation that automatically increases respiratory rate
D) The respiratory muscles become fatigued during physical activity
Answer: B) The body requires additional oxygen and needs to eliminate accumulated carbon
dioxide
Explanation: During exercise, skeletal muscles increase their metabolic activity, consuming
more oxygen and producing more carbon dioxide. The respiratory system responds by increasing
both rate and depth of breathing to meet these increased demands for oxygen uptake and carbon
dioxide elimination.
Question 7
A patient experiencing acute postoperative pain exhibits rapid, shallow breathing. What is the
primary reason for this respiratory pattern change?
A) Pain causes bronchodilation
B) Pain alters respiratory rate and rhythm, causing shallow breathing and limited chest wall
movement
C) Pain increases lung compliance
D) Pain stimulates the cough reflex
Answer: B) Pain alters respiratory rate and rhythm, causing shallow breathing and limited chest
wall movement
Explanation: Acute pain stimulates the sympathetic nervous system and causes muscle
splinting, which limits chest wall expansion. Patients often breathe shallowly to minimize pain
