QUESTIONS AND CORRECT ANSWERS
A nurse is collecting data from a client who is receiving Ringing in the ears
oxygen therapy. The nurse should identify that which of Rationale: The nurse should identify that ringing in the ears, as well as headache,
the following findings can indicate oxygen toxicity? disorientation, and muscle twitching, can indicate oxygen toxicity.
A nurse is caring for a client who is receiving Smoke inhalation
supplemental oxygen for hypoxia. The nurse should Rationale: The nurse should identify that smoke inhalation can cause hypoxia.
identify that which of the following can cause hypoxia? Smoke inhalation can cause a client to become hypoxic due to a lack of oxygen
and ventilation.
A nurse is caring for a client who has atelectasis. The Surfactant
nurse should identify that which of the following Rationale: The nurse should identify that surfactant is a lubricant required to keep
substances is required to keep the client's alveoli from alveoli in the lungs from collapsing during exhalation. A lack of surfactant can
collapsing and causing atelectasis? result in atelectasis.
A nurse is reinforcing teaching with a newly licensed The maximum volume of air that is expired after a maximum inspiration.
nurse about pulmonary function tests. The nurse should Rationale: The vital capacity is the amount of air that is forcibly expelled after a
include that which of the following is the vital capacity? maximal inspiration.
, A nurse is reinforcing teaching with a client who has a "Cover your nose with the CPAP mask."
new prescription for a continuous positive airway Rationale: The nurse should instruct the client to cover their nose with the CPAP
pressure (CPAP) machine to treat obstructive sleep mask to create a seal to treat obstructive sleep apnea. CPAP is used for
apnea. Which of the following statements should the obstructive sleep apnea to keep the upper airway open and increase a client's
nurse include? oxygenation.
A nurse is explaining the sequence of electrical SA node is the first step.
conduction in the heart to a newly licensed nurse. What AV node is the second step.

of performance. Use all the steps.) Rationale: SA node is the first step. The electrical impulses of the heart move from
the SA node, then to the AV node, then to the bundle of His, then to the right and
left bundle branches, and finally to the Purkinje fibers, to produce a heartbeat.
AV node is the second step. The electrical impulses of the heart move from the SA
node, then to the AV node, then to the bundle of His, then to the right and left
bundle branches, and finally to the Purkinje fibers, to produce a heartbeat.
Bundle of His is the third step. The electrical impulses of the heart move from the
SA node, then to the AV node, then to the bundle of His, then to the right and left
bundle branches, and finally to the Purkinje fibers, to produce a heartbeat.
Right and left bundle branches is the fourth step. The electrical impulses of the
heart move from the SA node, then to the AV node, then to the bundle of His, then
to the right and left bundle branches, and finally to the Purkinje fibers, to produce
a heartbeat.
Purkinje fibers is the fifth step. The electrical impulses of the heart move from the
SA node, then to the AV node, then to the bundle of His, then to the right and left
bundle branches, and finally to the Purkinje fibers, to produce a heartbeat.
A nurse is suctioning a client's tracheostomy using an Administer 100% oxygen before the procedure.
open system. Which of the following actions should the Rationale: The nurse should administer 100% oxygen to the client before the
nurse take? procedure to reduce the risk for hypoxia.
A nurse is assisting with planning to measure the cardiac Stroke volume
output of a client who had a myocardial infarction. Which Rationale: The nurse should use stroke volume to calculate the client's cardiac
of the following data should the nurse use to calculate output. Cardiac output is a measurement of the volume of blood pumped by the
the client's cardiac output? left ventricle in 1 min. Cardiac output is calculated by multiplying the client's heart
rate by the client's stroke volume.
