1. 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.

2. What is the most common cause of dementia among elderly persons?

• A. Parkinson’s disease
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis (Lou Gehrig’s disease)
• D. Alzheimer’s disease

Correct answer: D

Rationale: Alzheimer’s disease is the most common cause of dementia among elderly persons. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. While Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis are serious conditions, they are not typically associated with dementia in the same way Alzheimer’s disease is. Therefore, the correct answer is D.

3. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?

• A. 4,500/mm³
• B. 7,000/mm³
• C. 10,000/mm³
• D. 25,000/mm³

Correct answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.

4. 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.

5. A healthcare professional is preparing to administer an autologous blood product to a client. Which of the following actions should the professional take to identify the client?

• A. Match the client's blood type with the type and cross-match specimens
• B. Confirm the provider's prescription matches the number on the blood component
• C. Ask the client to state their blood type and the date of their last blood donation
• D. Ensure that the client's identification band matches the number on the blood unit

Correct answer: A

Rationale: When preparing to administer an autologous blood product, it is crucial to correctly identify the client to prevent errors. Matching the client's blood type with the type and cross-match specimens ensures that the blood product is intended for the correct recipient. This step helps in verifying the patient's identity and avoiding any transfusion-related complications. Confirming the blood type through type and cross-matching is a standard practice to ensure patient safety during blood transfusions.
