Nursing Elites

1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

• A. The body can produce sufficient amounts of vitamin D from sunlight.
• B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
• C. Sunscreen blocks the formation of vitamin D3.
• D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

2. The nurse understands that one of these factors contributes to constipation:

• A. excessive exercise
• B. high fiber diet
• C. no regular time for defecation daily
• D. prolonged use of laxatives

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. What characterizes Obsessive Compulsive Disorder?

• A. Uncontrollable impulse to perform an act or ritual repeatedly
• B. Persistent thoughts and behavior
• C. Recurring unwanted and disturbing thoughts
• D. Pathological persistence of unwilled thoughts

Correct answer: A

Rationale: Obsessive Compulsive Disorder (OCD) is characterized by the uncontrollable impulse to perform an act or ritual repeatedly (Choice A). This is driven by recurring unwanted and disturbing thoughts (Choice C), but the distinguishing factor is the compulsive behavior, making choice A the most accurate. While choice B can be seen as true, it lacks the specific detail of the compulsive behavior that makes A a better answer. Choice D is not incorrect, but it uses terminology that is less precise and less commonly used to describe OCD, making it a less accurate choice than A. The provided rationale is not relevant to the question.

4. Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:

• A. they must be supplied by the diet
• B. they can be produced by a process called dehydrogenation
• C. they are anti-inflammatory
• D. they are all polyunsaturated fatty acids

Correct answer: A

Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.

5. Why does Anita stand in front of the mirror while performing a Breast Self-Examination (BSE)?

• A. To check for unusual discharges from the breast
• B. To check for any obvious malignancy
• C. To observe the size and contour of the breast
• D. To check for thickness and lumps in the breast

Correct answer: C

Rationale: When performing a Breast Self-Examination (BSE), one of the reasons for standing in front of a mirror is to observe the size and contour of the breast (Choice C). This helps in identifying any visible changes or abnormalities such as dimpling, puckering, or changes in the size and shape of the breasts. While unusual discharges (Choice A) and thickness or lumps (Choice D) can be part of the changes a person might notice during a BSE, these are typically identified by palpation or by squeezing the nipple for discharge, not by just looking in the mirror. Choice B, checking for obvious malignancy, is too vague and not specific enough as malignancy is often not visible to the naked eye.
