Nursing Elites

1. Richard is a subject of a research lead by his doctor. The nurse knows that all of the following is a correct understanding as his right as a research subject except:

• A. I can withdraw with this research even after the research has been started
• B. My confidentiality will not be compromised in this research
• C. I must choose another doctor if I withdrew from this research
• D. I can withdraw with this research before the research has been started

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. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

• A. Cold compress reduces blood viscosity in the affected area
• B. It is safer to apply than a hot compress
• C. Cold compress prevents edema and reduces pain
• D. It eliminates toxic waste products due to vasodilation

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.

3. Which nutrient is most important for maintaining fluid balance in the body?

• A. Protein
• B. Sodium
• C. Calcium
• D. Vitamin C

Correct answer: B

Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.

4. Starting material for sex hormones:

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: A

Rationale: Cholesterol is a precursor for the synthesis of sex hormones like estrogen and testosterone.

5. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.
