Nursing Elites

1. What is the function of villi and microvilli in the GI tract?

• A. produce bile
• B. kill bacteria
• C. produce vitamin K
• D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

2. A nurse is caring for a client who is to receive a mechanically altered diet. Which of the following client food choices necessitates intervention by the nurse?

• A. Scrambled eggs
• B. Cottage cheese
• C. Piece of wheat toast
• D. Sliced banana

Correct answer: D

Rationale: The correct answer is 'Sliced banana.' A mechanically altered diet is designed for clients who have difficulty chewing or swallowing. Sliced bananas, due to their texture and potential choking hazard for clients with swallowing difficulties, would necessitate intervention by the nurse. Scrambled eggs, cottage cheese, and a piece of wheat toast are softer and safer options for clients on a mechanically altered diet, making them appropriate choices.

3. A client is being taught how to follow a low-purine diet for gout management. Which statement indicates the client understands the teaching?

• A. "I will need to limit the number of fruit servings each day."?
• B. "I should avoid eating liver and other organ meats."?
• C. "I can drink only white wine."?
• D. "I should choose red meat instead of poultry."?

Correct answer: B

Rationale: The correct answer is B. Organ meats like liver are high in purines, which can exacerbate gout symptoms. Choosing to avoid such foods is essential in following a low-purine diet. Option A is incorrect because fruits are generally low in purines and are not usually restricted in a low-purine diet. Option C is incorrect as white wine, just like other types of alcohol, should be consumed in moderation or avoided due to its purine content. Option D is incorrect because red meat, including beef and lamb, is high in purines and should be limited in a low-purine diet.

4. Match amylase with its digestive action:

• A. breaks down carbs
• B. breaks down proteins
• C. breaks down lipids
• D. helps fat digestion

Correct answer: A

Rationale: The correct answer is A: 'breaks down carbs.' Amylase is an enzyme that specifically targets carbohydrates, breaking them down into simpler sugars like maltose. This process aids in the digestion of carbohydrates in the human body. Choices B, C, and D are incorrect because amylase does not break down proteins, lipids, or directly aid fat digestion. Proteins are broken down by proteases, lipids are broken down by lipases, and fat digestion is primarily assisted by bile salts and lipases in the small intestine.

5. A nurse is providing teaching to a client with gastroesophageal reflux. Which of the following statements by the client indicates a need for further teaching?

• A. I should elevate the head of my bed while sleeping.
• B. I drink no more than 4 cups of coffee a day.
• C. I take my time when I am eating.
• D. I avoid foods and drinks made with chocolate.

Correct answer: B

Rationale: The correct answer is B: 'I drink no more than 4 cups of coffee a day.' Excessive coffee consumption can aggravate gastroesophageal reflux due to its acidic nature. Choices A, C, and D are all appropriate self-care measures for managing gastroesophageal reflux. Elevating the head of the bed while sleeping helps prevent acid reflux, eating slowly can reduce reflux episodes, and avoiding trigger foods like chocolate can help alleviate symptoms.
