Nursing Elites

1. As the head nurse in the OR, how can you improve the effectiveness of clinical alarm systems?

• A. Limit suppliers to a few so that quality is maintained
• B. Implement a regular inventory of supplies and equipment
• C. Adherence to manufacturer’s recommendation
• D. Implement a regular maintenance and testing of alarm systems

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. Why are LDLs known as the 'bad' type of cholesterol?

• A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

3. A nurse is assessing the nutritional status of an infant who is 6 months old. The infant weighed 2.7 kg at birth. Which of the following indicates to the nurse that the infant is within the expected range?

• A. 5.5 kg
• B. 6.4 kg
• C. 4.5 kg
• D. 3.6 kg

Correct answer: B

Rationale: The correct answer is B, 6.4 kg. An infant's weight should approximately double by 6 months. In this case, starting from a birth weight of 2.7 kg, a weight of 6.4 kg at 6 months indicates normal growth. Choice A (5.5 kg) is below the expected range for a 6-month-old infant. Choices C (4.5 kg) and D (3.6 kg) are also below the expected weight gain, indicating inadequate growth.

4. Which of the following are examples of mechanical digestion? Select all that apply.

• A. Heat
• B. Segmentation
• C. Option B and D
• D. Peristalsis

Correct answer: C

Rationale: Mechanical digestion involves physical movements that break down food in the digestive tract. Segmentation (choice B) and peristalsis (choice D), which are both movements of the muscles in the digestive tract, are examples of this type of digestion. Heat (choice A), on the other hand, is related to chemical digestion, not mechanical digestion. Therefore, choice C (Option B and D) is the correct answer as it includes both examples of mechanical digestion provided in the choices. Choices A and D are incorrect because heat (choice A) is not a mechanical digestion process, and peristalsis (choice D) is a movement that helps propel food along the digestive tract but is not directly involved in breaking down food physically.

5. A 52-year-old male patient recently required surgery for the removal of a large calcium oxalate stone. To prevent further stone formation, the nurse advises against drinking?

• A. apple juice
• B. tea
• C. orange juice
• D. coffee

Correct answer: B

Rationale: Tea contains oxalates, which can contribute to the formation of calcium oxalate stones; therefore, patients prone to kidney stones should avoid excessive tea consumption.
