1. During which stage of life is it most critical to build bone mass to prevent osteoporosis?
- A. Infancy
- B. Early childhood
- C. Adolescence
- D. Young adulthood
Correct answer: C
Rationale: Adolescence is the most critical stage for building bone mass, which plays a significant role in preventing osteoporosis in later life. During adolescence, approximately 45% of adult bone mass is formed. Although bone mass can be built during infancy, early childhood, and young adulthood, it is not as significant as during adolescence, making choices A, B, and D incorrect. Therefore, focusing on adequate nutrition and physical activity during adolescence is vital for long-term bone health.
2. You would expect that after an abdominal perineal resection, the type of colostomy that will be use is?
- A. Double barrel colostomy
- B. Temporary colostomy
- C. Permanent colostomy
- D. An Ileostomy
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.
3. What is the term for a condition where one or more members of a household, including children, consistently have little or no food due to lack of money?
- A. Marginal Food Security
- B. Food Desert
- C. Very Low Food Security
- D. Food Insecurity
Correct answer: D
Rationale: The correct answer is 'D: Food Insecurity'. This term specifically describes a situation where household members consistently have inadequate access to food due to financial constraints. 'Marginal Food Security' (Choice A) refers to a situation where the quality or variety of food is reduced, but there is no significant decrease in food intake. A 'Food Desert' (Choice B) is an area with limited access to affordable and nutritious food. 'Very Low Food Security' (Choice C) is a term used to describe a severe level of food insecurity where eating patterns of household members are disrupted and food intake is reduced.
4. What does oliguria lead to in patients with acute kidney injury?
- A. Hypophosphatemia and overgrowth of bone tissue
- B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
- C. Sodium retention and elevated levels of potassium
- D. Edema due to increased urine production
Correct answer: C
Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.
5. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?
- A. No—absorbed compounds show up in urine, not feces
- B. Yes—absorbed compounds show up in feces, not urine
- C.
- D.
Correct answer: A
Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.
