Nursing Elites

1. Which vitamin is primarily obtained from sunlight exposure?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is synthesized in the skin when it is exposed to sunlight. This process allows the body to produce Vitamin D naturally. Vitamin A (Choice A) is found in foods like liver and carrots and is not primarily obtained from sunlight. Vitamin C (Choice B) is commonly found in fruits and vegetables. Vitamin E (Choice D) is present in foods like nuts and seeds and is not primarily obtained from sunlight.

2. Before and after the operation, the operating suite is managed by the:

• A. Surgeon C. Nurse Manager
• B. Nurse Supervisor D. Chief Nurse
• C.
• D.

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. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.

4. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:

• A. Set and turn on the alarm of the oximeter
• B. Do nothing since there is no identified problem
• C. Cover the fingertip sensor with a towel or bedsheet
• D. Change the location of the sensor every four hours

Correct answer: B

Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.

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.
