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 condition is most closely associated with a high rate of gastroesophageal reflux disease?

• A. Pregnancy
• B. Anorexia
• C. Hypertension
• D. Diabetes mellitus

Correct answer: A

Rationale: Pregnancy is the correct answer as it is most closely associated with a high rate of gastroesophageal reflux disease (GERD). During pregnancy, the growing fetus exerts pressure on the stomach, leading to the backflow of stomach acid into the esophagus, causing GERD. This physiological change is a common occurrence in pregnant individuals. Conversely, anorexia, hypertension, and diabetes mellitus are not typically linked to a high rate of GERD. While these conditions have their own effects on the body, they do not directly contribute to the mechanisms that cause GERD, unlike the physical changes associated with pregnancy. Therefore, choices B, C, and D are incorrect.

3. What is the primary purpose of dietary fiber in the diet?

• A. Improving digestion
• B. Providing energy
• C. Aiding in the absorption of vitamins
• D. Reducing cholesterol

Correct answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.

4. Which food is a reliable source of B12 for a pregnant vegan client?

• A. Soybeans
• B. Algae
• C. Fortified soy milk
• D. Sea vegetables

Correct answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.

5. The priority nursing diagnosis for a client with major depression is:

• A. Altered nutrition
• B. Altered thought process
• C. Self care deficit
• D. Risk for injury

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
