1. Which type of lipid is solid at room temperature?
- A. Cholesterol
- B. Phospholipid
- C. Saturated fat
- D. Trans fat
Correct answer: C
Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.
2. Which dietary recommendation is most appropriate for a patient with gout?
- A. Increase protein intake
- B. Reduce carbohydrate intake
- C. Avoid purine-rich foods
- D. Increase calcium intake
Correct answer: C
Rationale: The most appropriate dietary recommendation for a patient with gout is to avoid purine-rich foods. Purine-rich foods such as red meat and shellfish can lead to increased uric acid levels in the body, triggering gout flare-ups. Increasing protein intake (Choice A) is not recommended as some high-protein foods are also high in purines. Reducing carbohydrate intake (Choice B) and increasing calcium intake (Choice D) are not directly related to managing gout symptoms.
3. Electrolytes create _____, which is caused by water following electrolytes within or between cells.
- A. energy
- B. active transport
- C. passive diffusion
- D. osmotic pressure
Correct answer: D
Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.
4. All of the following are seen in a child with measles. Which one is not?
- A. Reddened eyes
- B. Coryza
- C. Pustule
- D. Cough
Correct answer: C
Rationale: Measles typically presents with symptoms like reddened eyes, coryza (inflammation of the mucous membrane in the nose), and cough. However, pustules are not a common symptom of measles. Pustules are more characteristic of conditions like chickenpox rather than measles. Understanding these distinctions is crucial for accurate diagnosis and appropriate treatment.
5. Thiamin
- A. Vitamin B1
- B. Vitamin B2
- C. Vitamin B3
- D. Vitamin B12
Correct answer: A
Rationale: Thiamin, or Vitamin B1, plays a crucial role in energy metabolism and the proper functioning of the nervous system.
