A nurse is collecting data from a client who is receiving oxygen therapy. The nurse should identify that
which of the following findings can indicate oxygen toxicity? - Answer 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 is receiving supplemental oxygen for hypoxia. The nurse should identify
that which of the following can cause hypoxia? - Answer Smoke inhalation
Rationale: The nurse should identify that smoke inhalation 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 nurse should identify that which of the following
substances is required to keep the client's alveoli from collapsing and causing atelectasis? - Answer
Surfactant

from collapsing during exhalation. A lack of surfactant can result in atelectasis.
A nurse is reinforcing teaching with a newly licensed nurse about pulmonary function tests. The nurse
should include that which of the following is the vital capacity? - Answer The maximum volume of air
that is expired after a maximum inspiration.

A nurse is reinforcing teaching with 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? - Answer "Cover your nose with the CPAP mask."
Rationale: 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 explaining the sequence of electrical conduction in the heart to a newly licensed nurse. What
should the nurse include as the correct sequence of the transmission of electrical impulses? (Move the
steps into the box on the right, placing them in the selected order of performance. Use all the steps.) -
Answer SA node is the first step.
AV node is the second step.
Bundle of His is the third step.
Right and left bundle branches is the fourth step.
Purkinje fibers is the fifth step.
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 open system. Which of the following actions
