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. A healthcare professional in an emergency department is assessing a newly admitted client who is experiencing drooling and hoarseness following a burn injury. Which of the following actions should the healthcare professional take first?

• A. Obtain a baseline ECG.
• B. Obtain a blood specimen for ABG analysis.
• C. Insert an 18-gauge IV catheter.
• D. Administer 100% humidified oxygen.

Correct answer: D

Rationale: In a client experiencing drooling and hoarseness following a burn injury, airway compromise is a critical concern. Administering 100% humidified oxygen is the priority to ensure adequate oxygenation. This intervention takes precedence over obtaining baseline ECG, obtaining blood specimens, or inserting an IV catheter, as airway management and oxygenation are fundamental in the initial assessment and management of a client with potential airway compromise.

3. A healthcare professional is monitoring a group of clients for increased risk of developing pneumonia. Which of the following clients should the healthcare professional NOT expect to be at risk?

• A. Client who has dysphagia
• B. Client who has AIDS
• C. Client who was vaccinated for pneumococcus and influenza 6 months ago
• D. Client who has a closed head injury and is receiving ventilation

Correct answer: C

Rationale: A client who was vaccinated for pneumococcus and influenza 6 months ago would have a reduced risk of developing pneumonia compared to those who have not been vaccinated. Vaccination helps protect individuals from specific pathogens, thereby lowering the risk of infection. Clients with dysphagia, AIDS, or a closed head injury and receiving ventilation are at higher risk for pneumonia due to compromised immunity, respiratory function, or protective airway reflexes, respectively.

4. A client is being instructed on how to perform pursed-lip breathing. Which of the following should be included in the plan of care?

• A. Take quick breaths upon inhalation.
• B. Place your hand over your stomach.
• C. Take a deep breath in through your nose.
• D. Puff your cheeks upon exhalation.

Correct answer: C

Rationale: Pursed-lip breathing is a breathing technique that involves inhaling slowly through the nose and exhaling gently through pursed lips. This technique helps improve breathing efficiency and can be beneficial for individuals with respiratory conditions. Instructing the client to take a deep breath in through the nose is essential for proper execution of pursed-lip breathing, making choice C the correct answer.

5. Parenteral penicillin can be administered as an:

• A. IM injection or an IV solution
• B. IV or an intradermal injection
• C. Intradermal or subcutaneous injection
• D. IM or a subcutaneous injection

Correct answer: A

Rationale: Penicillin can be administered intramuscularly or intravenously.
