1. Which of the following is a process of heat loss that involves the transfer of heat from one surface to another?

• A. Radiation
• B. Conduction
• C. Convection
• D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Radiation (Choice A) is the transfer of heat through electromagnetic waves, while convection (Choice C) is the transfer of heat through the movement of fluids. Evaporation (Choice D) is a cooling process that involves the phase change of a liquid into a gas.

2. Why are hospital patients at greater risk for drug-nutrient interactions than they used to be?

• A. Hospitalized patients are more acutely ill
• B. Hospital routines interfere with the correct timing of medications
• C. Drugs used today are more toxic and have more side effects
• D. Responsibility for monitoring this is shared by various members of the healthcare team

Correct answer: A

Rationale: The correct answer is A. Hospitalized patients are at greater risk for drug-nutrient interactions because they are more acutely ill, often having multiple conditions and treatments that increase the risk of such interactions. Choice B is incorrect as hospital routines interfering with medication timing are not directly related to drug-nutrient interactions. Choice C is incorrect as the toxicity and side effects of drugs do not necessarily relate to interactions with nutrients. Choice D is incorrect as shared responsibility for monitoring does not directly contribute to the increased risk of drug-nutrient interactions in hospitalized patients.

3. A patient with a history of gout should avoid which type of food?

• A. Red meat
• B. Chicken
• C. Fish
• D. Dairy

Correct answer: A

Rationale: A patient with a history of gout should avoid foods high in purines, which can exacerbate gout attacks. Red meat is particularly high in purines, so it is the type of food that should be avoided. Chicken and fish are lower in purines compared to red meat, making them better choices for individuals with gout. Dairy products are generally not associated with triggering gout attacks, so they can be consumed in moderation by patients with gout.

4. What causes hepatic encephalopathy?

• A. Buildup of ammonia in the body
• B. Buildup of urea in the body
• C. Fatty infiltration of the liver
• D. Jaundice

Correct answer: A

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body. Ammonia, a byproduct of protein metabolism, normally gets converted to urea in the liver for excretion. However, in liver dysfunction, such as cirrhosis, the liver cannot effectively convert ammonia to urea, leading to its accumulation in the body and subsequently causing hepatic encephalopathy. Choices B, C, and D are incorrect as they do not directly relate to the pathophysiology of hepatic encephalopathy.

5. A patient with a history of peptic ulcer disease should avoid which medication?

• A. Acetaminophen
• B. Antacids
• C. Nonsteroidal anti-inflammatory drugs
• D. Antihistamines

Correct answer: C

Rationale: Patients with a history of peptic ulcer disease should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers. NSAIDs inhibit the production of prostaglandins, which help protect the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in patients with peptic ulcers. Antacids (Choice B) can actually help in symptom relief by neutralizing stomach acid. Antihistamines (Choice D) are not known to worsen peptic ulcers and are generally safe for use in patients with this condition.
