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 planning care for a client with severe acute respiratory distress syndrome (SARS), which of the following actions should not be included in the care plan?
- A. Administer antibiotics
- B. Provide supplemental oxygen
- C. Administer antiviral medications
- D. Administer bronchodilators
Correct answer: A
Rationale: Severe acute respiratory distress syndrome (SARS) is caused by a virus, not bacteria, and antibiotics are ineffective against viral infections. Therefore, administering antibiotics would not be appropriate in the care plan for a client with SARS. The priority interventions for SARS include providing supplemental oxygen to improve oxygenation, administering antiviral medications to target the viral infection, and using bronchodilators to help with bronchospasm or airway constriction. Antibiotics are not indicated unless there is a secondary bacterial infection present.
3. A client requests the creation of a living will. Which of the following actions should the nurse take?
- A. Schedule a meeting between the hospital ethics committee and the client.
- B. Evaluate the client's understanding of life-sustaining measures.
- C. Determine the client's preferences about post-mortem care.
- D. Request a conference with the client's family
Correct answer: B
Rationale: When a client requests the creation of a living will, the nurse's priority is to evaluate the client's understanding of life-sustaining measures. This involves ensuring that the client comprehends the implications of various life-sustaining interventions and can make informed decisions about their care preferences in the event they are unable to communicate them later. It is crucial for the nurse to assess the client's comprehension to ensure that the living will accurately reflects the client's wishes and values.
4. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: B
Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.
5. Which of the following is the correct meaning of CBR?
- A. Cardiac Board Room
- B. Complete Bathroom
- C. Complete Bed Rest
- D. Complete Board Room
Correct answer: C
Rationale: In medical terminology, 'CBR' stands for Complete Bed Rest. This term indicates the necessity for a patient to remain in bed without engaging in any physical activities beyond what is essential for daily living, to aid in the recovery process or to prevent further health complications. Choices A, B, and D are incorrect as they do not reflect the medical meaning of CBR.
