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. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?
- A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
- B. Circulatory overload due to hypervolemia
- C. Respiratory excitement
- D. Inhibition of the respiratory hypoxic stimulus
Correct answer: D
Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.
3. A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?
- A. Your urine can turn a dark orange.
- B. Watch for a change in the sclera of your eyes.
- C. Watch for any changes in vision.
- D. Take vitamin B6 daily.
Correct answer: C
Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.
4. What is the appropriate needle gauge for intradermal injection?
- A. 20G
- B. 22G
- C. 25G
- D. 26G
Correct answer: D
Rationale: Intradermal injections require a very fine needle to be used to deliver the medication into the dermis layer of the skin. A 26G needle is typically used for intradermal injections as it is thin enough to penetrate the skin's surface and deposit the medication accurately.
5. A 38-year-old patient’s vital signs at 8 a.m. are axillary temperature 99.6°F (37.6°C); pulse rate 88; respiratory rate 30. Which findings should be reported?
- A. Respiratory rate only
- B. Temperature only
- C. Pulse rate and temperature
- D. Temperature and respiratory rate
Correct answer: D
Rationale: Both an elevated temperature and an increased respiratory rate are abnormal vital signs that could indicate an underlying health issue. Reporting both of these findings is crucial to ensure appropriate evaluation and intervention if needed.
