Question 1 of 5
A client is receiving oxygen therapy via a nasal cannula. What is the appropriate flow rate for this client?
Correct Answer: B
Rationale: A flow rate of 4-6 liters per minute (B) is appropriate for nasal cannula oxygen therapy, delivering 36-44% oxygen, suitable for moderate hypoxemia. 1-2 L/min (A) (24-28%) suits mild cases or rest. 8-10 L/min (C) exceeds nasal cannula capacity, causing discomfort. 12-15 L/min (D) is for high-flow systems, not cannulas. This range balances efficacy and tolerance, per respiratory care standards, ensuring adequate oxygenation without nasal irritation.
Question 2 of 5
The nurse is caring for a client receiving oxygen therapy via a simple face mask. Which nursing intervention is important to prevent skin breakdown?
Correct Answer: C
Rationale: Padding pressure points with soft material (C) prevents skin breakdown from a simple face mask by reducing friction and pressure on the face. Repositioning q2h (A) helps but isn't enough alone. Barrier cream (B) is for moisture, not pressure. Intermittent removal (D) disrupts therapy. Padding, per skin integrity standards, is proactive.
Question 3 of 5
The nurse is caring for a client receiving oxygen therapy via a nasal cannula. Which action by the nurse is appropriate when providing oral care to the client?
Correct Answer: A
Rationale: Removing the nasal cannula during oral care (A) allows thorough hygiene without interference, briefly tolerable given short duration. Increasing flow (B) is unnecessary. Petroleum jelly (C) isn't for oral care. Mouth breathing (D) isn't needed if removed. Removal, per nursing practice, ensures effective care.
Question 4 of 5
Which of the following findings is associated with right-sided heart failure?
Correct Answer: B
Rationale: Nocturnal polyuria is linked to right-sided heart failure, where fluid shifts from edematous tissues to the bloodstream at night, increasing urine output as the heart struggles to pump against venous congestion. Shortness of breath and crackles typify left-sided failure, while daytime oliguria isn't specific. Nurses monitor this to assess heart function, guiding fluid management and diuretic use effectively.
Question 5 of 5
An 8-year-old admitted with an upper-respiratory infection has an order for O2 saturation via pulse oximeter. To ensure an accurate reading, the nurse should:
Correct Answer: D
Rationale: Placing the pulse oximeter probe on the finger ensures an accurate oxygen saturation reading in an 8-year-old, as peripheral sites like fingers provide reliable arterial pulsation data. The abdomen isn't suitable, recalibration isn't routine, and waiting 15 minutes delays care unnecessarily. Nurses use this technique for quick, precise monitoring, critical in respiratory infections to guide oxygen therapy.
