Medical Surgical Pneumonia #4


During the admission assessment, a hospitalized client with pneumonia is questioning the health care provider’s order for bedrest. Which statement by the nurse best explains the reason for the bedrest order?


  1. “Bedrest will reduce the demand for oxygen.”
    • Rationale:

      This answer is correct because the acute phase of pneumonia requires an effort to reduce oxygen demands on a cellular level which is already compromised by mucous and exudate interfering with gas exchange. Bedrest helps reduce the demand.

  2. “Bedrest will help you cough and deep breathe better.”
    • Rationale:

      This answer is not correct because, although reducing the demand for oxygen may allow for better exchange for adequate coughing and deep breathing, it will not be the reason for coughing and deep breathing.

  3. “Bedrest will help ease pain during coughing.”
    • Rationale:

      This answer is not correct because bedrest has no effect on pain experienced during coughing episodes. Teaching the client techniques such as using a pillow to splint during coughing will decrease pain.

  4. “Bedrest will give you a needed break from work and family.”
    • Rationale:

      This answer is not correct because a prescription for bedrest while hospitalized is not the cause for separation from family members or work. Family members will still be allowed to visit the client while on bedrest and the hospitalization prevents the client from attending work.


The focus of this question is providing the best rationale for a prescription for bedrest for a client with pneumonia. Pneumonia can lead to hypoxemia and decreased activity tolerance.


Learning Outcomes

Pneumonia is an inflammatory condition that affects the alveoli. The alveoli become inflamed and filled with fluids which decreases the effectiveness of gas exchange. Decreased gas exchange causes hypoxemia whis is exacerbated with activity. Bedrest decreases the client’s oxygen demand, therefore bedrest is prescribed.

Test Taking Tip

Think about the patho of the disease process that the question is addressing. Pneumonia is a lower respiratory disorder that causes hypoxemia and increased activity increases oxygen demand. So the BEST answer addresses the clients need for decreased oxygen demand.
