UPDATED test questions and CORRECT
Answers
A nurse is providing teaching for a client who has a new prescription for an incentive spirometer.
Which of the following instructions should the nurse include?
A. "Exhale into the incentive spirometer"
B. "Use the incentive spirometer every hour while awake"
C. "Hold your breath for 10 secs. when using the incentive spirometer"
D. Use the incentive spirometer two times each session - CORRECT ANSWERS B
***The nurse should instruct the client to use the incentive spirometer every hour while awake to
promote lung expansion and mobilize secretions.
A nurse is providing teaching for a client who has a new prescription for a continuous positive airway
pressure (CPAP) machine to treat obstructive sleep apnea. Which of the following statements should
the nurse include?
A. Use the CPAP mask during the daytime
B. Cover your nose with the CPAP mask
C. Medications to assist with breathing can be administered through the CPAP machine
D. You will need supplemental oxygen to use the CPAP machine - CORRECT ANSWERS B.
***The nurse should instruct the client to cover their nose with the CPAP mask to create a seal to
treat obstructive sleep apnea. CPAP is used for obstructive sleep apnea to keep the upper airway
open and increase a client's oxygenation.
A nurse is reviewing the medical history of a client who has heart disease and a narrowed valve.
Which of the following findings should the nurse expect?
A. Regurgitation
B. Stenosis
C. Muscle Atrophy
D. Hypotension - CORRECT ANSWERS B.
, ***The nurse should expect a client who has heart disease and a narrowed valve to have stenosis.
Stenosis is a narrowing or stiffening of the heart valve that causes backflow of the blood.
A nurse is assessing a client who is being discharged. The nurse notes the client has regular and quiet
breathing. The nurse should identify this breathing pattern as which of the following?
A. Normal breathing
B. Kussmaul breathing
C. Cheyne-Stokes breathing

A nurse is caring for a client who has a history of asthma and is wheezing. Which of the following
actions should the nurse take first?
A. Auscultate the lung sounds.
B. Document the respiratory rate
C. Obtain the oxygen saturation.
D. Check the capillary refill - CORRECT ANSWERS C.
***The greatest risk to this client is injury from hypoxia; therefore, the first action the nurse should
take is to obtain the client's oxygen saturation. Obtaining the client's oxygen saturation will assist
the nurse in determining the next intervention.
A nurse is caring for a client who has atelectasis. The nurse should identify that which of the
following substance is required to keep the client's alveoli from collapsing and causing atelectasis?
A. Lymphatic fluid
B. Oxygenated blood,
C. Synovial fluid
D. Surfactant - CORRECT ANSWERS D.
*** The nurse should identify that surfactant is a lubricant required to keep alveoli in the lungs from
collapsing during exhalation. A lack of surfactant can result in atelectasis.
