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. The mechanism behind most CKD in patients without diabetes is mediated by:

• A. enzyme systems
• B. immune systems
• C. catabolic systems
• D. hormonal systems

Correct answer: B

Rationale: In non-diabetic patients, CKD is often mediated by immune system responses. Chronic inflammation triggered by immune system dysfunction can contribute to progressive kidney damage. Therefore, the correct answer is 'immune systems.' Choices A, C, and D are incorrect because CKD in non-diabetic patients is primarily associated with immune system abnormalities rather than enzyme, catabolic, or hormonal systems.

3. Which type of assessment evaluates a person's risk of malnutrition by ranking key variables from the medical history and physical examination?

• A. Katz index
• B. integrated assessment
• C. subjective global assessment
• D. nutrition care plan

Correct answer: C

Rationale: The Subjective Global Assessment (SGA) is the correct choice. SGA is a comprehensive tool used to assess an individual's risk of malnutrition by integrating key variables from the medical history, physical examination, and other relevant factors. The Katz index is used to assess activities of daily living, not malnutrition risk. An integrated assessment refers to the overall evaluation process involving multiple assessments. A nutrition care plan is a personalized plan developed based on assessment findings, not the assessment itself.

4. The counting of sponges is done by the Surgeon together with the:

• A. Circulating nurse
• B. Scrub nurse
• C. Assistant surgeon
• D. Nurse supervisor

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

5. Which of the following is a common sign of vitamin D deficiency?

• A. Brittle nails
• B. Muscle weakness
• C. Night blindness
• D. Hair loss

Correct answer: B

Rationale: Muscle weakness is a common sign of vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to muscle weakness. Brittle nails (Choice A) are not typically associated with vitamin D deficiency. Night blindness (Choice C) is related to vitamin A deficiency, not vitamin D deficiency. Hair loss (Choice D) can be linked to various factors, but it is not a common sign of vitamin D deficiency.
