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 providing teaching to a group of adult athletes about preventing the effects of dehydration on the body. Which of the following manifestations should the nurse include in the teaching?

• A. Impaired motor control
• B. Drop in body temperature during exercise
• C. Increase in appetite
• D. Decreased resting heart rate

Correct answer: A

Rationale: Dehydration can lead to impaired motor control due to electrolyte imbalances affecting muscle function. Choices B, C, and D are incorrect. Dehydration typically causes an increase in body temperature during exercise, not a drop. Dehydration is more likely to suppress appetite, leading to a decrease rather than an increase in appetite. Also, dehydration often results in an increased heart rate rather than a decreased resting heart rate.

3. A patient is admitted to the emergency room and is found to have proteinuria, a low serum albumin level, edema, and elevated blood lipids. Which condition do these symptoms typically associate with?

• A. Nephrotic syndrome
• B. Acute kidney injury
• C. Rejection of a kidney transplant
• D. Renal colic

Correct answer: A

Rationale: The correct answer is A: Nephrotic syndrome. Nephrotic syndrome is characterized by proteinuria (excess protein in urine), hypoalbuminemia (low serum albumin), edema (swelling due to fluid buildup), and hyperlipidemia (elevated blood lipids). These symptoms occur as a result of damage to the kidneys' filtering units. Acute kidney injury, rejection of a kidney transplant, and renal colic do not present with the same combination of symptoms as nephrotic syndrome. Acute kidney injury typically presents with a sudden decrease in kidney function, resulting in a build-up of waste products in the blood. Rejection of a kidney transplant may present with fever, pain at the transplant site, and changes in urine output. Renal colic usually presents with intense pain in the lower back or side, related to kidney stones.

4. Each of the following is a characteristic of fat, except one. Which is the exception?

• A. 95% of ingested fats are absorbed
• B. Hard fats take longer to digest than soft fats
• C. Fats contribute to palatability and flavor of foods
• D. Cooked fats improve the texture of foods

Correct answer: B

Rationale: The correct answer is B. Hard fats take longer to digest than soft fats because hard fats are solid at body temperature, making them more challenging to break down. Choice A is true as the majority of ingested fats are absorbed. Choice C is correct as fats indeed contribute to the palatability and flavor of foods. Choice D is accurate as cooked fats can enhance the texture of foods.

5. In order to establish and maintain successful breastfeeding, which practice should a lactating mother try to follow?

• A. Initiate breastfeeding within 24 hours of birth
• B. Breastfeed on a schedule of every 2 to 3 hours
• C. Give a pacifier to an infant between feedings
• D. Find a breastfeeding support group to troubleshoot problems

Correct answer: D

Rationale: The correct answer is D. Finding a breastfeeding support group is crucial for a lactating mother to establish and maintain successful breastfeeding. This group can offer valuable advice, tips, and encouragement, helping the mother troubleshoot any issues that may arise during breastfeeding. Choices A, B, and C are incorrect because breastfeeding is a natural process that should not be overly scheduled, and giving a pacifier between feedings can interfere with establishing proper breastfeeding techniques.
