1. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

2. A nurse is reinforcing teaching about food choices with the mother of an 8-month-old infant. Which of the following statements by the mother indicates a need for further teaching?

• A. I will give my child strained carrots and mashed egg yolks.
• B. I will give my child rice cereal and crackers.
• C. I will give my child pureed liver and strained pears.
• D. I will give my child applesauce and green peas.

Correct answer: B

Rationale: Choice B, 'I will give my child rice cereal and crackers,' indicates a need for further teaching. Infants should not be given crackers at 8 months of age due to the risk of choking. Rice cereal is appropriate for infants, but it should be introduced carefully to avoid digestive issues. Choices A, C, and D are appropriate food choices for an 8-month-old infant, providing a variety of nutrients and textures suitable for their age and developmental stage.

3. Can fluid retention cause lab values to be deceptively high, whereas dehydration may cause the values to be deceptively low?

• A. TRUE
• B. FALSE
• C. Not always
• D. Sometimes

Correct answer: B

Rationale: The statement is incorrect. Fluid retention generally results in lab values appearing deceptively low, not high, because the excess fluid dilutes the concentration of substances in the blood. Conversely, dehydration can make lab values appear deceptively high as the reduced fluid volume in the body means substances in the blood are less diluted. Choices 'C: Not always' and 'D: Sometimes' are not specific and do not directly address the statement in the question, hence they are incorrect.

4. A healthcare professional is preparing an education program for a group of parents of adolescents. Which of the following should be included as indicators of nutritional risk among adolescents? (Select one that does not apply.)

• A. Skipping more than three meals per week
• B. Eating fast food once weekly
• C. Eating without family supervision frequently
• D. Frequently skipping breakfast

Correct answer: B

Rationale: Among the indicators of nutritional risk among adolescents, skipping meals, eating without family supervision, and frequently skipping breakfast are commonly associated with poor nutrition. However, eating fast food once weekly may not necessarily indicate a significant nutritional risk, as occasional consumption of fast food in moderation is not uncommon among adolescents. This choice is the correct answer because it does not strongly correlate with nutritional risk compared to the other options provided.

5. A nurse is providing teaching to a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

• A. Albumin in my urine is an indication of normal kidney function.
• B. I will keep my HbA1c at five percent.
• C. I will have ketones in my urine if my blood glucose is maintained at 190 milligrams per deciliter.
• D. I will keep my blood glucose levels between 200 and 212 milligrams per deciliter.

Correct answer: B

Rationale: The correct answer is B. Maintaining an HbA1c level of 5 percent indicates good long-term blood glucose control and understanding of diabetes management. Choice A is incorrect because the presence of albumin in the urine (albuminuria) is actually an indication of kidney damage in diabetes. Choice C is incorrect as ketones in the urine are a sign of inadequate insulin and can occur when blood glucose levels are high, not at a specific level like 190 mg/dL. Choice D is also incorrect as the client should aim to keep blood glucose levels within a tighter range for better control, typically between 80-130 mg/dL before meals and less than 180 mg/dL after meals.
