1. Which of the following conditions may necessitate fluid restriction?

• A. Fever
• B. Chronic Obstructive Pulmonary Disease
• C. Renal Failure
• D. Dehydration

Correct answer: C

Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.

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. Examples of patients suffering from impaired awareness include all of the following except:

• A. A semiconscious or overfatigued patient
• B. A disoriented or confused patient
• C. A patient who cannot care for themselves at home
• D. A patient demonstrating symptoms of drug or alcohol withdrawal

Correct answer: C

Rationale: Patients with impaired awareness may exhibit symptoms such as being semiconscious, overfatigued, disoriented, confused, or demonstrating symptoms of drug or alcohol withdrawal. A patient who cannot care for themselves at home does not necessarily indicate impaired awareness, as this could be due to physical limitations or lack of support, rather than a cognitive deficit.

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. What is the appropriate needle size for insulin injection?

• A. 18G, 1 ½” long
• B. 22G, 1” long
• C. 22G, 1 ½” long
• D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.
