A practical nurse is caring for a client who was admitted with
community-acquired pneumonia. Four hours after admission, the client
becomes restless and confused. Assessment findings include a
respiratory rate of 34/min, oxygen saturation of 86% on room air, heart
rate of 118/min, and crackles throughout both lung fields. Which action
should the nurse take first?
A. Notify the provider of the client's condition.
B. Encourage the client to cough and deep breathe.
C. Apply supplemental oxygen as prescribed.
D. Obtain a sputum specimen.
Answer: C. Apply supplemental oxygen as prescribed.
Rationale: Using the ABC priority framework, impaired oxygenation is
the highest priority. Administering oxygen immediately helps improve
, tissue oxygenation while further interventions are arranged. Notifying
the provider is appropriate after stabilizing the client's airway and
breathing. Coughing and deep breathing are helpful but will not rapidly
correct severe hypoxemia. A sputum specimen can be obtained after
the client's respiratory status is stabilized.
A nurse is caring for a client 12 hours after a total hip arthroplasty.
While assisting the client to reposition in bed, the client suddenly
reports severe hip pain, and the affected leg appears shortened and
internally rotated. Which action should the nurse take?
A. Reposition the affected leg into alignment.
B. Continue turning the client onto the operative side.
C. Immobilize the leg and notify the provider immediately.
D. Encourage the client to perform range-of-motion exercises.
Answer: C. Immobilize the leg and notify the provider immediately.
Rationale: Shortening and internal rotation strongly suggest hip
dislocation, a surgical emergency. The nurse should avoid manipulating
the joint, maintain the current position, and notify the provider
immediately. Attempting to realign the extremity could worsen the
injury.
