Nursing Elites

1. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

2. The physician orders the administration of high-humidity oxygen by face mask and placement of the patient in a high Fowler’s position. After assessing Mrs. Paul, the nurse writes the following nursing diagnosis: Impaired gas exchange related to increased secretions. Which of the following nursing interventions has the greatest potential for improving this situation?

• A. Encourage the patient to increase her fluid intake to 200 ml every 2 hours
• B. Place a humidifier in the patient’s room
• C. Continue administering oxygen by high humidity face mask
• D. Perform chest physiotherapy on a regular schedule

Correct answer: D

Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.

3. A patient presents with an exacerbation of chronic obstructive pulmonary disease (COPD) characterized by shortness of breath, orthopnea, thick, tenacious secretions, and a dry hacking cough. An appropriate nursing diagnosis would be:

• A. Ineffective airway clearance related to thick, tenacious secretions.
• B. Ineffective airway clearance related to dry, hacking cough.
• C. Ineffective individual coping with COPD.
• D. Pain related to immobilization of affected leg.

Correct answer: A

Rationale: The patient's symptoms of shortness of breath, orthopnea, thick, tenacious secretions, and a dry hacking cough all point towards a potential airway clearance issue. This makes option A, 'Ineffective airway clearance related to thick, tenacious secretions,' the most appropriate nursing diagnosis. It directly addresses the thick secretions and suggests a potential cause of the breathing difficulty the patient is experiencing.

4. A client is receiving vecuronium for acute respiratory distress syndrome. Which of the following medications should the nurse anticipate administering with this medication?

• A. Fentanyl
• B. Furosemide
• C. Famotidine
• D. Dexamethasone

Correct answer: A

Rationale: Vecuronium is a neuromuscular blocking agent used for muscle relaxation during mechanical ventilation. When administering vecuronium, it is common to also give an opioid analgesic, such as fentanyl, to manage pain and ensure the patient's comfort. Fentanyl is often used in combination with neuromuscular blocking agents to provide balanced anesthesia, making it the appropriate medication to anticipate administering in this scenario.

5. When is sterile technique used?

• A. During strict isolation procedures
• B. After terminal disinfection is performed
• C. For invasive procedures
• D. When protective isolation is necessary

Correct answer: C

Rationale: Sterile technique is utilized during invasive procedures to prevent the introduction of pathogens, minimizing the risk of infections. This strict approach ensures that the procedure is performed in a sterile environment, reducing the chances of contamination and subsequent complications.
