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.

A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:
- A. Infection
- B. Hypothermia
- C. Anxiety
- D. Dehydration
Correct Answer: D
Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.
The four main concepts common to nursing that appear in each of the current conceptual models are:

During a Romberg test, the patient is asked to assume which position?
- A. Sitting
- B. Standing
- C. Genupectoral
- D. Trendelenburg
Correct Answer: B
Rationale: During a Romberg test, the patient is asked to stand with feet together and arms at the sides. The test evaluates proprioception and vestibular function by assessing the patient's ability to maintain balance with eyes closed. Asking the patient to stand helps to detect any balance issues or disturbances in the absence of visual input.
