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. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

• A. Semipermeable membranes.
• B. Hydration.
• C. Osmotic pressure.
• D. Perspiration.

Correct answer: C

Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.

3. In PEM, which condition is characterized by symptoms such as muscle weakness, hanging skin, delayed tooth eruption, and changes in saliva?

• A. Marasmus
• B. Kwashiorkor
• C. Anemia
• D. Noma

Correct answer: A

Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.

4. The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.

5. 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.
