Nursing Elites

1. Which factor has been shown to increase the risk of development of atherosclerosis?

• A. Menopause
• B. Age older than 35
• C. Increased levels of arachidonic acid
• D. Elevated HDL cholesterol

Correct answer: A

Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.

2. Given that orthodontic patients are frequently adolescents, their nutrition and oral self-care are often subpar. A dental hygienist may successfully motivate these noncompliant patients by emphasizing that optimal nutrition and oral self-care can enhance their appearance. Is this true or false?

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are indeed true. Many adolescents undergoing orthodontic treatment often neglect proper nutrition and oral hygiene, leading to subpar practices in these areas. It's common for them to be less attentive to these aspects due to various factors. A dental hygienist's role includes motivating these patients towards better self-care practices. One effective approach is by emphasizing that good nutrition and oral hygiene can significantly enhance their appearance. This approach is particularly effective for adolescents as they are often highly conscious about their looks. The other choices are incorrect because they suggest that one or both of the statements are false, which is not the case.

3. Mrs. Pichay who is for thoracentesis is assigned by the nurse to any of the following positions, EXCEPT:

• A. straddling a chair with arms and head resting on the back of the chair
• B. lying on the unaffected side with the bed elevated 30-40 degrees
• C. lying prone with the head of the bed lowered 15-30 degrees
• D. sitting on the edge of the bed with her feet supported and arms and head on a padded overhead table

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.

4. Each statement is true of swallowing and processing food, except one. Which is the exception?

• A. The swallowing reflex moves a bolus into the esophagus
• B. A bolus is a mass of food
• C. The bolus is transported to the stomach by osmosis and gravity
• D. The bolus penetrates the diaphragm through the esophageal hiatus

Correct answer: C

Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.

5. Fatty acids may differ from one another:

• A. in chain length
• B. in degree of saturation
• C. in number of calories
• D.

Correct answer: D

Rationale: Fatty acids vary in chain length and degree of saturation, affecting their physical properties and health effects.
