1. Which enzyme digests fiber in the large intestine?
- A. salivary amylase
- B. pancreatic amylase
- C. cellulase
- D. none of the above
Correct answer: D
Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.
2. What instruction should a nurse include when teaching a client who has recently been prescribed a low-sodium diet?
- A. Avoid foods such as smoked meats and frozen dinners.
- B. Select foods with less than 4g of sodium as indicated on food labels.
- C. Use soy sauce for flavoring foods instead of table salt.
- D. Processed and prepared foods are typically low in sodium.
Correct answer: A
Rationale: The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.
3. Mrs. Pichay who is for thoracentesis is assigned by the nurse to any of the following positions, EXCEPT:
- A. straddling a chair with arms and head resting on the back of the chair
- B. lying on the unaffected side with the bed elevated 30-40 degrees
- C. lying prone with the head of the bed lowered 15-30 degrees
- D. sitting on the edge of the bed with her feet supported and arms and head on a padded overhead table
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. What should be recommended to help prevent early childhood caries (ECC) in infants?
- A. Avoid giving the infant nighttime bottles
- B. Have the infant drink pasteurized skim milk
- C. Feed the infant iron-rich foods
- D. Give the infant fruit juice to drink
Correct answer: A
Rationale: The correct answer is 'A: Avoid giving the infant nighttime bottles' because prolonged exposure to sugars in milk during the night can lead to caries. Options 'B: Have the infant drink pasteurized skim milk' and 'D: Give the infant fruit juice to drink' are not recommended as they contain sugars that can cause cavities, especially in infants. Option 'C: Feed the infant iron-rich foods' is incorrect because while a balanced diet is important, iron-rich foods do not directly prevent caries development.
5. Medication for treating high blood cholesterol levels should not be used for most people unless:
- A. The patient has at least three major risk factors for coronary heart disease
- B. The patient has been experiencing symptoms of coronary heart disease for at least three months
- C. The patient's medical insurance covers prescription drugs
- D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months
Correct answer: D
Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.
