ATI ENGAGE FUNDAMENTALS: RN GAS
EXCHANGE AND OXYGENATION
ASSESSMENT 2.0. EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS
A nurse is assessing a client who is receiving oxygen therapy. The nurse should identify that
which of the following findings can indicate oxygen toxicity? - ANS Ringing in the ears
Rationale: The nurse should identify that ringing in the ears, as well as headache,
disorientation, and muscle twitching, can indicate oxygen toxicity.
A nurse is caring for a client who has atelectasis. The nurse should identify that which of the
following substances is require to keep the client's alveoli from collapsing and causing
atelectasis? - ANS Surfactant
Rationale: 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.
A nurse is auscultating a client's heart sound and hears a low-pitched whooshing or blowing
sound over the apex of the heart. The nurse should identify that this indicates which of the

, A nurse is planning to measure the cardiac output of a client who has had a myocardial
infarction. Which of the following data should the nurse use to calculate the client's cardiac
output? - ANS Stroke volume
Rationale: The nurse should use stroke volume to calculate the client's cardiac output. Cardiac
output is a measurement of the volume of blood pumped by the left ventricle in 1 min. Cardiac
output is calculated by multiplying the client's heart rate by the client's stroke volume.
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? - ANS Obtain the oxygen saturation
Rationale: 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 assessing a client who has COPD. The nurse should identify that which of the
following is an expected finding? - ANS Clubbing of the fingers
Rationale: The nurse should identify that clubbing of the fingers is an expected finding for a
client who has a chronic pulmonary disease, such as COPD.
A nurse is caring for a client who has left-sided heart failure. Which of the following findings
should the nurse expect? - ANS Crackles in the lungs
Rationale: The nurse should expect the client who has left-sided heart failure to have crackles in
the lungs. Left-sided heart failure causes the blood to back up into the pulmonary circulation,
causing crackles in the lungs.
A nurse is planning care for a group of clients on a cardiopulmonary unit. Which of the following
clients should the nurse plan to see first? - ANS A client who reports dyspnea when walking
to the bathroom
