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. A client with Crohn's disease is being cared for by a nurse. Which of the following food choices aligns with the recommended diet for clients with Crohn's disease?

• A. Vanilla milkshake
• B. Buttered popcorn
• C. Tossed green salad
• D. Toast with jelly

Correct answer: C

Rationale: The correct answer is a 'Tossed green salad.' Clients with Crohn's disease often benefit from a low-residue diet, which includes easily digestible foods like leafy green vegetables found in a tossed green salad. This type of diet helps minimize gastrointestinal symptoms. Choices A, B, and D are not ideal for clients with Crohn's disease. Vanilla milkshake, buttered popcorn, and toast with jelly may exacerbate symptoms due to their high fat, fiber, or sugar content, which can be harder to digest.

3. Is the statement 'The metabolic rate is the highest after a few hours of sleep' true or false?

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: The statement is false. The metabolic rate is actually lowest during sleep and increases upon waking. During sleep, the body conserves energy, leading to a lower metabolic rate. As the body wakes up and becomes active, the metabolic rate increases to support the body's functions and energy needs. Therefore, the metabolic rate is not the highest after a few hours of sleep, making the statement false.

4. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

5. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
