Nursing Elites

1. What physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

2. Clients with type 2 diabetes are most likely to achieve metabolic control if they:

• A. lose weight
• B. use self-monitoring of blood glucose
• C. eliminate all dietary sugars
• D. eat three regular meals daily

Correct answer: A

Rationale: Weight loss improves insulin sensitivity and glycemic control, making it a key strategy in managing type 2 diabetes.

3. The following are appropriate nursing interventions during colostomy irrigation, EXCEPT:

• A. Increase the irrigating solution flow rate when abdominal cramps is felt
• B. Insert 2-4 inches of an adequately lubricated catheter to the stoma
• C. Position client in semi-Fowler
• D. Hang the solution 18 inches above the stoma

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.

4. What is the most significant dietary influence on the development of dental caries?

• A. Carbohydrates
• B. Vitamins
• C. Minerals
• D. Fats

Correct answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

5. A client who has dumping syndrome following a hemi-colectomy should avoid which of the following foods when receiving nutritional teaching from a nurse?

• A. Rice
• B. Poached eggs
• C. Fresh apples
• D. White bread

Correct answer: C

Rationale: Fresh apples should be avoided by a client with dumping syndrome following a hemi-colectomy because they are high in fiber and can exacerbate gastrointestinal symptoms such as diarrhea and bloating. Rice and poached eggs are good options as they are easily digestible and less likely to trigger dumping syndrome symptoms. White bread is also preferable over whole grain bread due to its lower fiber content, making it a better choice for individuals with dumping syndrome.
