Nursing Elites

1. Which of the following provides the least amount of potassium?

• A. broccoli
• B. potatoes
• C. bananas
• D. cheese

Correct answer: D

Rationale: Cheese provides less potassium compared to broccoli, potatoes, and bananas, which are all rich in this essential mineral.

2. 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.

3. A client with diabetes is being taught by a nurse about the dietary source that should provide the greatest percentage of calories. Which of the following statements indicates the client understands the teaching?

• A. "Most of my calories each day should be from fats."?
• B. "I should eat more calories from complex carbohydrates than anything else."?
• C. "Simple sugars are needed more than other calorie sources."?
• D. "Protein should be my main source of calories."?

Correct answer: B

Rationale: The correct answer is '"I should eat more calories from complex carbohydrates than anything else."?' Clients with diabetes should focus on complex carbohydrates as their primary calorie source because they have a lower impact on blood sugar levels compared to simple sugars or fats. Choice A is incorrect because a high intake of fats can lead to various health issues. Choice C is incorrect because simple sugars can cause rapid spikes in blood sugar levels. Choice D is incorrect as while protein is important, it should not be the main source of calories for someone with diabetes.

4. After bronchoscopy, the nurse's priority is to check which of the following before feeding?

• A. Gag reflex
• B. Wearing off of anesthesia
• C. Swallowing reflex
• D. Peristalsis

Correct answer: A

Rationale: After a bronchoscopy procedure, the nurse's priority is to check the patient's gag reflex before allowing them to eat to prevent aspiration. The gag reflex helps protect the airway by triggering a cough or gag response if something touches the back of the throat. This is crucial to ensure that the patient can protect their airway and prevent food or fluids from entering the lungs, especially when the throat may be sensitive or compromised post-bronchoscopy. Checking for the wearing off of anesthesia, swallowing reflex, or peristalsis are important assessments but not the immediate priority before feeding in this context.

5. Which of the following is a form of primary prevention?

• A. Regular Check-ups
• B. Regular Screening
• C. Self-Medication
• D. Immunization

Correct answer: D

Rationale: The correct answer is D, 'Immunization.' Primary prevention aims to prevent disease before it occurs by preventing exposure to risk factors. Immunization is a classic example of primary prevention as it helps prevent the development of infectious diseases. Choice A, 'Regular Check-ups,' is more related to secondary prevention by detecting diseases early. Choice B, 'Regular Screening,' is also more aligned with secondary prevention as it involves early detection of diseases. Choice C, 'Self-Medication,' is not a form of primary prevention but rather a risky practice that can lead to adverse outcomes.
