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. When caring for a client on pressure support ventilation (PSV), which statement by the nurse indicates an understanding of PSV?
- A. It keeps the alveoli open and prevents atelectasis.
- B. It allows preset pressure delivered during spontaneous ventilation.
- C. It guarantees minimal minute ventilator.
- D. It delivers a preset ventilatory rate and tidal volume to the client.
Correct answer: B
Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.
3. A healthcare professional is planning care for a client following the insertion of a chest tube and drainage system. Which of the following should NOT be included in the plan of care?
- A. Encourage the client to cough every 2 hours.
- B. Check for continuous bubbling in the suction chamber.
- C. Strip the drainage tubing every 4 hours.
- D. Obtain a chest x-ray
Correct answer: C
Rationale: Stripping the drainage tubing is an outdated practice and can cause complications. Encouraging the client to cough helps with lung expansion, checking for continuous bubbling ensures proper functioning of the chest tube system, and obtaining a chest x-ray helps to assess the position of the chest tube and re-expansion of the lung. Therefore, stripping the drainage tubing every 4 hours should not be included in the plan of care.
4. A nurse manager is reviewing documentation with a newly licensed nurse. Which of the following notations by the newly licensed nurse indicates an understanding of the teaching?
- A. ''OOB with assistance for breakfast''
- B. ''Given 2 mg MSO4 IM for report of pain''
- C. ''Dressing changed qd''
- D. ''Administered 8 units of regular insulin subcutaneously''
Correct answer: D
Rationale: The correct answer demonstrates proper documentation by specifying the action taken ('Administered'), the dose ('8 units'), the medication ('regular insulin'), and the route of administration ('subcutaneously'). This notation ensures clarity and accuracy in recording the nursing intervention, aligning with best practices in documentation.
5. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?
- A. Confusion
- B. Pale skin
- C. Bradycardia
- D. Hypotension
Correct answer: B
Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.
