A nurse is assessing a client for hypoxemia during an asthma attack. Which of the following manifestations should the nurse expect?
Nausea
Dysphagia
Agitation
Hypotension
The Correct Answer is C
Agitation is a sign of hypoxemia, as the brain is deprived of oxygen and becomes irritable and restless.
The other options are not correct because:
- Nausea is not a specific manifestation of hypoxemia, as it can have many other causes such as medication side effects, gastrointestinal disorders, or anxiety.
- Dysphagia is difficulty swallowing, which is not related to hypoxemia or asthma. It can be caused by neurological, muscular, or structural problems in the throat or esophagus.
- Hypotension is low blood pressure, which is not a typical manifestation of hypoxemia or asthma. It can be caused by dehydration, blood loss, shock, or heart failure.

Correct Answer is ["A","C","E"]
Explanation
These are important safety and comfort measures for a client who uses home oxygen therapy via a nasal cannula.
The other options are not correct because:
b. Verify the oxygen flow rate every other day. This is not frequent enough, as the flow rate should be checked at least daily and whenever the client feels short of breath or has changes in vital signs.
d. Apply petroleum ointment to nares if they become dry and irritated. 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.
