1. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

2. Located in the middle of the brain, what organ is responsible for satiety and hunger?

• A. Medulla Oblongata
• B. Pituitary Gland
• C. Hypothalamus
• D. Parathyroid

Correct answer: C

Rationale: The hypothalamus, located in the middle of the brain, plays a crucial role in regulating hunger and satiety. It contains specific regions that control appetite and feeding behavior. The Medulla Oblongata (Choice A) is responsible for regulating vital functions like heartbeat and breathing, not hunger. The Pituitary Gland (Choice B) is an endocrine gland that secretes hormones but is not primarily involved in hunger regulation. The Parathyroid (Choice D) is responsible for regulating calcium levels in the body and not related to hunger or satiety.

3. Each statement is true of water-soluble vitamins, except one. Which is it?

• A. Act as coenzymes
• B. Deficiencies develop rapidly
• C. Daily intake is necessary
• D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.

4. A client receiving continuous enteral tube feeding reports cramping and abdominal distention. Which of the following actions should the nurse take?

• A. Check for gastric residual.
• B. Apply low intermittent suction.
• C. Increase the rate of the feeding.
• D. Request a higher-fat formula.

Correct answer: A

Rationale: When a client on continuous enteral tube feeding experiences cramping and abdominal distention, the nurse should check for gastric residual. This assessment helps determine if the client is tolerating the feeding well or if there is a potential issue such as feeding intolerance. Applying low intermittent suction, increasing the feeding rate, or requesting a higher-fat formula are not appropriate actions for addressing the reported symptoms and may exacerbate the client's discomfort or lead to further complications.

5. A guideline that is utilized in determining priorities is to assess the status of the following, EXCEPT:

• A. perfusion
• B. locomotion
• C. respiration
• D. mentation

Correct answer: D

Rationale: When determining priorities in patient care, assessing perfusion, respiration, and locomotion are crucial. However, assessing mentation is also important but not typically included in the ABCs of emergency care. Monitoring mentation is essential for neurological assessment and detecting changes in mental status, but it is not part of the immediate priorities in life-threatening situations.
