Question

The nurse clarifies that the condition in which there is a decreased amount of oxygen in the blood is:

Answer 1

Correct Answers:

hypoxemia

Rationale :

🟠 Hypoxemia is defined as a decreased amount of oxygen in the blood, specifically in the arterial blood.

🟠 It differs from hypoxia, which refers to insufficient oxygen in the tissues despite adequate blood flow.

🟠 Hypercapnia is an increased level of carbon dioxide in the blood, not oxygen deficiency.

🟠 Dyspnea describes the subjective experience of breathing difficulty or shortness of breath.

🟠 Recognizing hypoxemia early is critical for preventing complications such as tissue damage or organ dysfunction.

Answer 2

Correct Answers:

Store oxygen tanks upright.

Rationale :

▶️ Oxygen tanks must be stored upright to prevent damage to the valve and to ensure safe gas flow.

▶️ Keeping oxygen tanks away from heat sources (not necessarily 4 feet, but at a safe distance) is important to prevent fire hazards.

▶️ Wool blankets are a fire risk and should not be used near oxygen.

▶️ Petroleum-based ointments are flammable and contraindicated with oxygen use.

▶️ Proper storage and safety precautions reduce risks associated with home oxygen therapy.

Answer 3

Correct Answers:

pharyngeal airway

Rationale :

⚫ A pharyngeal airway is used to prevent the tongue from falling back and obstructing the airway in patients who can breathe independently but have airway obstruction risk.

⚫ An endotracheal tube is invasive and generally used when the patient cannot maintain an airway or requires mechanical ventilation.

⚫ A partial rebreather mask delivers oxygen but does not address airway obstruction caused by the tongue.

⚫ A tracheostomy is a surgical airway and reserved for long-term airway management.

⚫ The pharyngeal airway is a less invasive device appropriate for this clinical situation.

Answer 4

Correct Answers:

taping all connections within the system

Rationale :

🟤 Taping all connections in a disposable chest drainage system ensures there are no accidental disconnections, preventing air leaks and maintaining the system's integrity.

🟤 The suction should be set as prescribed and is not always 35 cm; too high suction can cause tissue damage.

🟤 The drainage system must be kept below the patient’s chest level to allow gravity drainage, not at chest level.

🟤 Looping tubing can cause kinks and obstruct drainage; it should be kept free of loops and dependent on gravity.

🟤 Securing tubing connections optimizes drainage and patient safety

Answer 5

Correct Answers:

A nonrebreather mask should fit snugly over a client's face.

Rationale :

🟢 A snug fit prevents air leaks and ensures delivery of high concentrations of oxygen.

🟢 The reservoir bag should not collapse completely during inhalation; if it does, oxygen flow needs adjustment.

🟢 Nonrebreather masks can cause drying of mucous membranes, so humidification may be necessary.

🟢 They deliver high-flow oxygen, not low-flow.

🟢 Proper use ensures effective oxygen delivery and patient comfort.

Answer 6

Correct Answers:

"Hold your breath for 5 seconds."

Rationale :

🔶 Coughing and deep breathing exercises promote alveolar expansion and help mobilize secretions after surgery.

🔶 Instructing the client to hold their breath for 5 seconds allows air to reach all lung areas, increasing alveolar inflation and oxygenation.

🔶 This technique is essential in preventing postoperative atelectasis and pneumonia.

🔶 The client should take a deep breath in, hold it, and then exhale forcefully to maximize lung expansion.

Answer 7

Correct Answers:

Tripod

Rationale :

🟢 The tripod position (sitting and leaning forward with hands on knees or an overbed table) facilitates maximum lung expansion.

🟢 This posture optimizes diaphragm movement and reduces the work of breathing in respiratory distress.

🟢 It helps in improving oxygenation and is often instinctively assumed by clients with dyspnea.

🟢 It also promotes effective use of accessory muscles of respiration.

Answer 8

Correct Answers:

midaxillary line on the rib cage

Rationale :

🔵 Chest physiotherapy with percussion targets areas where mucus accumulates, typically the posterior and lateral lobes of the lungs.

🔵 The midaxillary line on the rib cage gives direct access to the lower lobes, a common site for mucus pooling.

🔵 Avoiding bony prominences like the sternum or spine prevents injury and enhances therapeutic effectiveness.

🔵 Percussion over this area loosens secretions, promoting easier coughing and expectoration.

Answer 9

Correct Answers:

Set the vacuum pressure at 120 mmHg for suctioning.

Rationale :

🟤 For pediatric tracheostomy suctioning, vacuum pressure should be 80–120 mmHg to prevent mucosal damage.

🟤 Excessive suction duration or pressure can cause hypoxia, bradycardia, and tissue trauma.

🟤 Using appropriate pressure ensures effective suctioning while minimizing risks.

🟤 Only normal saline or sterile water—not hydrogen peroxide—should be used near the airway.

Answer 10

Correct Answers:

Cleanse the mask or collar with soapy water every other day.
Post "no smoking" warning signs at home in a prominent location.
Make sure the straps on the mask are secure but not too tight.
Check the tops of his ears regularly for skin breakdown.

Rationale :

❇️ Cleanse the mask or collar with soapy water every other day.

🔸 Regular cleaning prevents the accumulation of bacteria, dirt, and mucus, which can obstruct airflow and harbor pathogens.

🔸 Using mild soap and water ensures the oxygen equipment remains sanitary and safe for respiratory use.

🔸 Allowing the mask to air-dry completely before reuse also helps prevent skin irritation or mold growth.

❇️ Post "no smoking" warning signs at home in a prominent location.

🔸 Oxygen is a highly flammable gas, and even a small spark can lead to fire in oxygen-enriched environments.

🔸 Posting “no smoking” signs clearly communicates the danger to all visitors and household members.

🔸 This is a critical safety measure that aligns with home oxygen therapy protocols and promotes injury prevention.

❇️ Make sure the straps on the mask are secure but not too tight.

🔸 The mask must be snug to ensure effective oxygen delivery, but not so tight that it causes pressure sores or skin irritation.

🔸 Straps that are too loose may result in oxygen leakage, reducing therapeutic effectiveness.

🔸 Teaching the client and family how to assess fit ensures comfort and continuous oxygen benefit.

❇️ Check the tops of his ears regularly for skin breakdown.

🔸 Oxygen tubing can rub against the ears, especially when worn continuously, leading to skin breakdown or ulceration.

🔸 Regular inspection helps catch early signs of redness or pressure damage, allowing for prompt intervention.

🔸 Padding or repositioning the tubing can be used to relieve pressure and maintain skin integrity.
