The nurse enters a client's room with a pulse oximetry machine and tells the client that the health care provider (HCP) has prescribed continuous oxygen saturation readings. The client's facial expression changes to one of apprehension. The nurse can alleviate the client's anxiety by providing which information about pulse oximetry?
It causes only mild discomfort at the site the probe is placed.
It requires insertion of only a small catheter in one nostril.
It is painless and safe.
It has an alarm to signal dangerous drops in oxygen levels.
The Correct Answer is C
A. It causes only mild discomfort at the site the probe is placed: Pulse oximetry is noninvasive and typically does not cause any discomfort unless the probe is left on too long or applied too tightly.
B. It requires insertion of only a small catheter in one nostril: This refers to oxygen delivery via nasal cannula, not pulse oximetry. Mentioning catheter insertion may increase the client’s apprehension, as it implies an invasive procedure, which pulse oximetry is not.
C. It is painless and safe: Pulse oximetry is a noninvasive method that uses light to measure oxygen saturation through a fingertip or earlobe, making it both painless and very safe for continuous monitoring.
D. It has an alarm to signal dangerous drops in oxygen levels: While accurate, focusing on alarms may heighten the client’s anxiety by implying that dangerous events are expected. This information is more relevant after the client is reassured about the procedure’s safety.

Correct Answer is ["2450"]
Explanation
Calculation:
- Jevity at 50 mL/hr from 2000 to 0600 (10 hours):
50 mL/hr × 10 hr = 500 mL
- Free water flush at 0615:
= 50 mL
- Red blood cells (2 units of 250 mL) from 2100–0215:
250 mL × 2 = 500 mL
- IV saline flushes:
0115: 20 mL
0400: 10 mL
Total = 30 mL
- Zosyn IV at 0300:
= 50 mL
- Continuous fluids:
Heparin: 10 mL/hr × 12 hr = 120 mL
Normal Saline: 100 mL/hr × 12 hr = 1,200 mL
Total = 1,320 mL
Total Intake Calculation:
- Jevity: 500 mL
- Water flush: 50 mL
- RBCs: 500 mL
- Saline flushes: 30 mL
- Zosyn: 50 mL
- Continuous fluids: 1,320 mL
Total intake = 500 + 50 + 500 + 30 + 50 + 1,320 = 2,450 mL
Final Answer: 2,450 mL intake from 7 p.m. to 7 a.m.
Correct Answer is D
Explanation
A. A venturi mask: The Venturi mask is often used in patients with COPD. However, it may cause dryness and irritation in the nasal passages and sinuses due to non-humidified, high-flow delivery, which could aggravate existing sinus conditions.
B. A nasal cannula: While nasal cannulas are less drying than masks and suitable for low-flow oxygen delivery, they can still cause mucosal dryness when used without humidification, particularly in patients with sinus issues.
C. High-flow oxygen via nasal cannula: High-flow nasal cannula therapy provides warmed, humidified oxygen, but at higher rates than needed for most patients starting oxygen therapy. It is more appropriate for acute respiratory failure than for routine use in sinus conditions.
D. Adding humidification to the oxygen setup: Humidifying oxygen helps prevent nasal and sinus mucosal dryness and irritation, making it beneficial for patients with sinus disorders. Moisture improves comfort and protects the integrity of the upper airway mucosa during oxygen therapy.
