Nursing Elites

1. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

2. Which of the following ethical principles refers to the duty to do good?

• A. Beneficence
• B. Fidelity
• C. Veracity
• D. Nonmaleficence

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. After consuming a meal high in fat, the _____ releases _______ to aid in digestion.

• A. stomach, acid
• B. liver, bile
• C. pancreas, bicarbonate
• D. gallbladder, bile

Correct answer: D

Rationale: The gallbladder releases bile into the small intestine to help digest fats. Bile emulsifies fats, breaking them down into smaller droplets for easier digestion. The stomach primarily releases gastric acid, the liver produces bile but stores it in the gallbladder, and the pancreas secretes bicarbonate to neutralize stomach acid in the small intestine. Therefore, choices A, B, and C are incorrect.

4. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?

• A. TRUE
• B. FALSE
• C. Not applicable
• D. Not applicable

Correct answer: A

Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.

5. Which type of drug is most likely to cause unintentional weight gain?

• A. Antiemetics
• B. Sedatives
• C. Corticosteroids
• D. Antibiotics

Correct answer: C

Rationale: Corticosteroids are most likely to cause unintentional weight gain. They influence the metabolism and fat distribution in the body, leading to weight gain. On the other hand, antiemetics are drugs that are used to prevent nausea and vomiting, and they do not typically cause weight gain. Sedatives, while they can cause drowsiness and may lead to less physical activity, are not directly associated with weight gain. Lastly, antibiotics are used to fight bacteria and while they can cause temporary digestive issues, they do not typically result in long-term weight gain.
