Nursing Elites

1. Although a balanced diet is essential for tissue healing and repair, which of the following should the dental hygienist identify as the nutrient of highest priority for a patient with gingivitis or periodontal disease?

• A. Carbohydrates
• B. Vitamin C
• C. Vitamin D
• D. Monosaccharides

Correct answer: B

Rationale: Vitamin C is crucial for collagen production and connective tissue repair, making it a key nutrient for healing gingival tissues in patients with gingivitis or periodontal disease. Carbohydrates are a source of energy and not directly related to tissue repair. Vitamin D is important for bone health but is not the highest priority for gingival tissue healing. Monosaccharides are simple sugars and not as essential for tissue repair as Vitamin C.

2. A vegan patient might be at risk for deficiency in which of the following nutrients?

• A. Vitamin B12
• B. Vitamin C
• C. Carbohydrates
• D. Fiber

Correct answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.

3. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

4. To prevent recurrent attacks on client with glomerulonephritis, the nurse instructs the client to:

• A. Take a shower instead of tub baths
• B. Avoid situations that involve physical activity
• C. Continue the same restriction on fluid intake
• D. Seek early treatment for respiratory infection

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.

5. A fire has broken in the unit of DMLM R.N. The best leadership style suited in cases of emergencies like this is:

• A. Autocratic
• B. Participative
• C. Democratic
• D. Laissez Faire

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.
