begins carb digestion in the mouth

ATI RN

ATI Nutrition Practice A

1. Begins carb digestion in the mouth:

A. pepsin
B. salivary amylase
C. CCK
D. secretin

Correct answer: B

Rationale: Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth by breaking down starches into simpler sugars.

2. A nurse is teaching about nutrition to a client who has a new diagnosis of chronic kidney disease. Which of the following recommendations should the nurse include in the teaching?

A. Increase phosphorus intake
B. Limit calcium intake
C. Limit protein intake
D. Increase potassium intake

Correct answer: C

Rationale: The correct recommendation for a client with chronic kidney disease is to limit protein intake. Excessive protein consumption can strain the kidneys as they work to eliminate waste products from protein metabolism. This can worsen kidney function in individuals with chronic kidney disease. Therefore, limiting protein intake is crucial in managing this condition. Choices A, B, and D are incorrect. Increasing phosphorus intake can be harmful in kidney disease as it can lead to mineral imbalances. Limiting calcium intake is not typically necessary unless the client has specific complications. Increasing potassium intake may also be inappropriate as potassium levels can be affected in kidney disease.

3. Which condition is an example of a potential cause of gastritis?

A. bile reflux
B. low salt intake
C. hypophosphatasia
D. gallstones

Correct answer: A

Rationale: Bile reflux is a potential cause of gastritis as it can irritate the stomach lining when bile backs up into the stomach. Choices B, C, and D do not directly cause gastritis. Low salt intake is not a common cause of gastritis. Hypophosphatasia is a rare genetic disorder affecting bone development, not the stomach. Gallstones, while related to the gallbladder, are not a direct cause of gastritis.

4. A nurse is providing teaching to a group of parents of newborns who are planning to formula feed. Which of the following statements by a parent indicates a need for further teaching?

A. "I will give formula to my baby at room temperature."
B. "I will ensure my baby's feeds last 10 to 15 minutes."
C. "I will burp my baby halfway through each feeding."
D. "I will watch for signs my baby is full and stop the feeding."

Correct answer: B

Rationale: The correct answer is, "I will ensure my baby's feeds last 10 to 15 minutes." This statement indicates a need for further teaching because it suggests a strict time limit for feedings, which may not be appropriate for a newborn. Newborns should be allowed to feed as long as they want, typically around 20-30 minutes per breast if breastfeeding, or on-demand with formula. Choices A, C, and D demonstrate proper feeding practices such as feeding at room temperature, burping halfway through each feeding, and watching for signs of fullness to stop the feeding, which are all appropriate responses by a parent of a formula-fed newborn.
