A nurse is assessing a client who has postoperative atelectasis and is hypoxic. Which of the following manifestations should the nurse expect?
Lethargy
Bradycardia
Intercostal retractions
Bradypnea
The Correct Answer is C
Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.
a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.

Correct Answer is B
Explanation
A humidifier bottle adds moisture to the oxygen, which prevents drying and irritation of the nasal mucosa
and enhances gas exchange.
a. Remove the nasal cannula while the client eats. This is not advisable, as the client may become hypoxic during eating, especially if they have pneumonia and impaired lung function. The nurse should monitor the client's oxygen saturation and respiratory status during meals and adjust the oxygen delivery device as needed.
c. Secure the oxygen tubing to the bed sheet near the client's head. This is not safe, as it can cause entanglement, dislodgement, or kinking of the tubing, which can compromise oxygen delivery and cause injury to the client.
d. Apply petroleum jelly to the nares as needed to soothe mucous membranes. This is not recommended, as petroleum products can ignite in the presence of oxygen and cause burns or fire. A water-based lubricant should be used instead.
Correct Answer is B
Explanation
Suctioning is the priority observation in the client's care, as it prevents airway obstruction and respiratory distress caused by blood, mucus, or secretions. The client has a permanent tracheostomy and cannot cough
or clear the airway effectively. The nurse should assess the need for suctioning frequently and perform it as needed, using sterile technique and maintaining oxygenation.
a) Patency of the intravenous line is important, but not the priority observation in the client's care. The intravenous line provides fluids, electrolytes, and medications to the client, but it does not affect the airway patency or oxygenation.
c) Integrity of the dressing is important, but not the priority observation in the client's care. The dressing protects the surgical site from infection and bleeding, but it does not affect the airway patency or oxygenation.
d) Level of pain is important, but not the priority observation in the client's care. The pain can be managed with analgesics and nonpharmacological measures, but it does not affect the airway patency or oxygenation.
