Nursing Elites

1. Salome was fitted a hearing aid. She understood the proper use and wear of this device when she says that the battery should be functional, the device is turned on and adjusted to a:

• A. therapeutic level
• B. comfortable level
• C. prescribed level
• D. audible level

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

2. Which mineral-containing amino acids help to form the shape of proteins?

• A. phosphorus
• B. sulfur
• C. selenium
• D. iron

Correct answer: B

Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.

3. A client with diabetes is being taught by a nurse about the dietary source that should provide the greatest percentage of calories. Which of the following statements indicates the client understands the teaching?

• A. "Most of my calories each day should be from fats."?
• B. "I should eat more calories from complex carbohydrates than anything else."?
• C. "Simple sugars are needed more than other calorie sources."?
• D. "Protein should be my main source of calories."?

Correct answer: B

Rationale: The correct answer is '"I should eat more calories from complex carbohydrates than anything else."?' Clients with diabetes should focus on complex carbohydrates as their primary calorie source because they have a lower impact on blood sugar levels compared to simple sugars or fats. Choice A is incorrect because a high intake of fats can lead to various health issues. Choice C is incorrect because simple sugars can cause rapid spikes in blood sugar levels. Choice D is incorrect as while protein is important, it should not be the main source of calories for someone with diabetes.

4. Worldwide, what is the most common nutrient deficiency?

• A. magnesium deficiency
• B. iron deficiency
• C. selenium deficiency
• D. zinc deficiency

Correct answer: B

Rationale: Iron deficiency is the most common nutrient deficiency globally. It leads to anemia and affects many populations, especially women and children. Magnesium, selenium, and zinc deficiencies are important, but they are not as prevalent as iron deficiency on a global scale.

5. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
