1. Which is NOT a characteristic or function of lipids?

A. Involved in energy metabolism and storage
B. Provide insulation and protection
C. Act as hormones that regulate the body
D. Are hydrophilic

Correct answer: D

Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.

2. Weight loss therapies that rely on juicing typically provide increased fiber, vitamins, and minerals. As an added incentive, juices contain a lower concentration of sugar than the whole fruit. Are these statements true or false?

A. Both statements are true
B. Both statements are false
C. The first statement is true; the second is false
D. The first statement is false; the second is true

Correct answer: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

3. Why are LDLs known as the 'bad' type of cholesterol?

A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
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: A

Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

4. Pain medications given to the burn clients are best given via what route?

A. IV C. Oral
B. IM D. SQ
C.
D.

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. The nurse is caring for an infant whose parent reports the infant takes a bottle to go to sleep. What should the nurse instruct to prevent baby bottle tooth decay?

A. Water
B. Milk
C. Iron-fortified formula
D. Unsweetened fruit juice

Correct answer: A

Rationale: The correct answer is A, Water. Water is recommended to prevent baby bottle tooth decay caused by sugary substances present in milk, formula, or fruit juice. Water does not contain sugars that can contribute to tooth decay, unlike the other options. Milk, formula, and unsweetened fruit juice can all lead to tooth decay if the baby falls asleep with them in their mouth, as the sugars can linger on the teeth and cause decay over time. Iron-fortified formula, although beneficial for the infant's nutrition, still contains sugars that can be harmful to the teeth.
