Nursing Elites

1. Which cells in the islet of the pancreas are responsible for synthesizing insulin?

• A. Alpha cells
• B. Beta cells
• C. Gamma cells
• D. Delta cells

Correct answer: B

Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.

2. Medication for treating high blood cholesterol levels should not be used for most people unless:

• A. The patient has at least three major risk factors for coronary heart disease
• B. The patient has been experiencing symptoms of coronary heart disease for at least three months
• C. The patient's medical insurance covers prescription drugs
• D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months

Correct answer: D

Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.

3. What percentage of body weight as fat does a woman with a healthy body composition typically average?

• A. 5%
• B. 15%
• C. 25%
• D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

4. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:

• A. First degree burn C. Third degree burn
• B. Second degree burn D. Partial thickness burn
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. During nutritional counseling, what is the most important step to take?

• A. Consult the patient's family
• B. Formulate a sample diet plan before presenting it to the patient
• C. Include members of the dental team in the dietary formulation
• D. Include the patient in the formulation of the dietary plan

Correct answer: D

Rationale: During nutritional counseling, the most important step is to include the patient in the formulation of the dietary plan. This ensures their active involvement, understanding, and commitment to the plan, leading to better compliance and success in achieving nutritional goals. Consulting the patient's family (Choice A) may be helpful but should not replace involving the patient directly. Formulating a sample diet plan before presenting it to the patient (Choice B) may not align with the patient's preferences or needs. Including members of the dental team in the dietary formulation (Choice C) may not be necessary unless specific dental concerns need to be addressed.
