The nurse is providing care to a client with asthma. Which clinical manifestations does the nurse expect to assess? Select one that doesn't apply.

Correct Answer: C

Rationale: Wheezing (A), cough (B), and increased respiratory rate (D) are common in asthma due to airway obstruction and inflammation. Hypotension (C) is not typical.

Correct Answer: D

Rationale: Proper placement of the cannula tips ensures oxygen is delivered effectively to the patient's respiratory system, which is the primary goal of oxygen therapy.

Correct Answer: D

Rationale: Oxygen makes up 21% of the air in the atmosphere, as matched in the document.

Correct Answer: C

Rationale: Close assessment of the patient before, during, and after the procedure is necessary to limit negative effects. Risks include hypoxia, infection, tracheal tissue damage, dysrhythmias, and atelectasis. The nurse should hyperoxygenate the patient before and after suctioning and limit the application of suction to 10 to 20 seconds. The nurse should also take the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. Using an appropriate suction pressure (80 to 150 mm Hg) will help prevent atelectasis related to the use of high negative pressure. (Note: E is 'Use an appropriate suction pressure (80 to 150 mm Hg)' from the provided options.)

Correct Answer: B

Rationale: Tachycardia (2) and irritability (5) are early signs of hypoxemia as the body compensates for low oxygen before later signs like cyanosis or flaring nares appear.
