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.

Which of the following patients is at greatest risk for developing pressure ulcers?
- A. An alert chronic arthritic patient treated with steroids and aspirin
- B. An 88-year-old incontinent patient with gastric cancer who is confined to bed at home
- C. An apathetic 63-year-old COPD patient receiving nasal oxygen via cannula
- D. A confused 78-year-old patient with congestive heart failure (CHF) who requires assistance to get out of bed
Correct Answer: B
Rationale: The correct answer is B. An elderly patient who is incontinent, bedridden, and suffering from a serious illness like gastric cancer is at the highest risk for developing pressure ulcers. Being bedridden and incontinent increases the pressure on certain areas of the body, leading to tissue damage and the development of pressure ulcers. Additionally, the patient's age and underlying health condition further contribute to their risk. It is crucial to identify and address such risk factors promptly to prevent the occurrence of pressure ulcers in vulnerable patients.

Which of the following statements about chest X-rays is false?
- A. There are contraindications for this test
- B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
- C. A signed consent is not required
- D. Eating, drinking, and medications are allowed before this test
Correct Answer: A
Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging. While a signed consent is typically not required for a routine chest X-ray, there are specific situations where consent may be necessary. It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.
