1. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

• A. pancreatic amylases, small intestine
• B. brush border enzymes, small intestine
• C. luminal enzymes, large intestine
• D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

2. A patient is being discharged with a vitamin K deficiency. What food should the nurse recommend to the patient to include in their diet?

• A. Oranges
• B. Spinach
• C. Fish
• D. Nuts

Correct answer: B

Rationale: Spinach is an excellent source of vitamin K, which plays a vital role in blood clotting and bone health. Oranges, fish, and nuts do not contain significant amounts of vitamin K, making them less suitable choices to address a vitamin K deficiency. Therefore, the correct recommendation for a patient with a vitamin K deficiency would be to include spinach in their diet to help replenish this essential vitamin.

3. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?

• A. Graciela’s buttocks are resting on the bed.
• B. The traction weights are hanging 10 inches above the floor.
• C. Graciela’s legs are suspended at a 90 degree angle to her trunk.
• D. The traction ropes move freely through the pulley.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?

• A. 5
• B. 5.5
• C. 6
• D. 6.5

Correct answer: B

Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.

5. What symptoms would most likely be associated with a transient ischemic attack?

• A. confusion and difficulty speaking
• B. headache and blurred vision
• C. chest pain and pressure
• D. claudication and peripheral edema

Correct answer: A

Rationale: The correct answer is A: confusion and difficulty speaking. These symptoms are commonly associated with a transient ischemic attack (TIA), which is a temporary blockage of blood flow to the brain. Choice B, headache and blurred vision, are more indicative of other conditions such as migraines or eye problems. Choice C, chest pain and pressure, are more characteristic of cardiac issues like a heart attack. Choice D, claudication and peripheral edema, are typical of peripheral arterial disease and not typically seen in TIAs.
