A polysomnogram was ordered for a client. The nurse will instruct the client that it requires an overnight stay in a sleep lab. Which of the following explanations about the test does the nurse give to the client?

1. Records several physiologic parameters during sleep
2. Occurs 2 hours after awakening from the overnight sleep study
3. Consists of five 20-minute nap trials
4. Requires a 24-hour interval of sleep deprivation

Question 2

The nurse is preparing a plan of care for a newly admitted client with chronic obstructive pulmonary disease (COPD). The client currently is receiving oxygen at 4 liters per nasal cannula.

Her oxygen saturation is 82, respiratory rate is 32, heart rate is 98, and blood pressure is 102/68. Which of the following is the highest-priority nursing diagnosis for this client? 1. Activity Intolerance
2. Ineffective Tissue Perfusion
3. Ineffective Airway Clearance
4. Ineffective Management of Therapeutic Regimen

Answer to Question 1

1. Records several physiologic parameters during sleep

Rationale:
The polysomnogram records physiologic parameters such as brain waves and eye movements during sleep. The multiple sleep latency test (MSLT) occurs 2 hours after awakening from the overnight sleep study. Nap trials are part of the MSLT. The polysomnogram does not require a 24-hour sleep deprivation.

Answer to Question 2

2. Ineffective Tissue Perfusion

Rationale:
Ineffective tissue perfusion is a priority nursing diagnosis for a client with hypoxemia. Without the adequate perfusion of tissues with oxygen, the client will not be able to tolerate activity or manage the therapeutic regimen. The assessment findings do not state that the client has a productive cough, so ineffective airway clearance may or may not be appropriate at this time.
