1. Fat-soluble vitamins are different from water-soluble vitamins because the body is able to store only small amounts of fat-soluble vitamins.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: C

Rationale: The statement is correct, but the reason is not correct. A major difference between fat-soluble and water-soluble vitamins is that the body is able to store larger amounts of fat-soluble vitamins. Vitamins A and D are stored for long periods; therefore, minor shortages might not be identified until drastic depletion has occurred. Observable signs and symptoms of a dietary deficiency are often not identified until they are in an advanced state. Water-soluble vitamins, on the other hand, are not stored in the body and are excreted in the urine if taken in excess, making it harder to reach toxic levels.

2. What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?

• A. conserving calcium stores
• B. contracting the uterus
• C. protecting against future hypertension
• D. speeding the resumption of ovulation

Correct answer: B

Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.

3. You are to measure the client's initial blood pressure reading by doing all of the following EXCEPT:

• A. Take the blood pressure reading on both arms for comparison
• B. Listen to and identify the phases of Korotkoff sounds
• C. Pump the cuff to around 50 mmHg above the point where the pulse is obliterated
• D. Observe procedures for infection control

Correct answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.

4. Low levels of high-density lipoproteins (HDL) are?

• A. associated with being underweight
• B. more prevalent in males
• C. highly predictive of CHD risk
• D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

5. Which individual would be at the greatest risk for deficiencies in water-soluble vitamins?

• A. An individual who regularly consumes fruits and vegetables.
• B. An individual with a high intake of dairy products.
• C. An individual who consumes a diet high in processed foods.
• D. An individual who frequently eats organ meats.

Correct answer: C

Rationale: The correct answer is 'An individual who consumes a diet high in processed foods.' Processed foods are often deficient in water-soluble vitamins such as vitamin C and B vitamins, which can lead to deficiencies. On the other hand, fruits, vegetables, and organ meats are rich sources of these vitamins, so individuals who consume these regularly are less likely to develop deficiencies. While dairy products do contain some water-soluble vitamins, they are not depleted as quickly as they are in a diet high in processed foods, making a deficiency less likely.
