Nursing Elites

1. 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.

2. A client with pre-dialysis end-stage kidney disease is being taught about diet. Which of the following instructions should the nurse include?

• A. Increase intake of dietary phosphorus.
• B. Eliminate foods high in protein from your diet.
• C. Reduce intake of foods high in potassium.
• D. Increase intake of sodium-containing foods.

Correct answer: C

Rationale: In pre-dialysis end-stage kidney disease, reducing intake of foods high in potassium is crucial as impaired kidney function can lead to potassium buildup in the blood, which can be dangerous. High potassium levels can cause irregular heartbeats and even cardiac arrest. Therefore, advising the client to reduce potassium-rich foods is essential to prevent complications. Choices A, B, and D are incorrect. Increasing dietary phosphorus, eliminating foods high in protein, or increasing sodium-containing foods are not appropriate recommendations for a client with pre-dialysis end-stage kidney disease as they can exacerbate the condition.

3. A healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?

• A. Measure the tube length.
• B. Obtain an abdominal x-ray.
• C. Flush the tube with 20 mL of water.
• D. Auscultate the client’s lungs.

Correct answer: B

Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.

4. In approximately what percentage of cases is the prevalence seen?

• A. Type 1 Diabetes
• B. Type 2 Diabetes
• C. N/A
• D. N/A

Correct answer: A

Rationale: The correct answer is A, Type 1 Diabetes. The prevalence of Type 1 Diabetes is seen in approximately 5% to 10% of cases. This statement highlights a key epidemiological characteristic of Type 1 Diabetes. Choice B, Type 2 Diabetes, is incorrect because the prevalence mentioned does not align with Type 2 Diabetes, which has a much higher prevalence in the general population. Choices C and D are not relevant to the question and can be disregarded.

5. What is the role of fat in digestion?

• A. Digest fats in the stomach
• B. Emulsify fats in the small intestine
• C. Transport fats through the circulatory system
• D. Split fats into smaller components

Correct answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.
