1. 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.

2. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

A. energy
B. active transport
C. passive diffusion
D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

3. A client is receiving education from a nurse regarding the dietary changes needed for weight loss. Which of the following actions should the nurse perform first?

A. Educate the client about daily caloric requirements.
B. Determine the client’s daily caloric intake.
C. Provide the client with meal planning information.
D. Show the client how to identify the fat content of packaged foods.

Correct answer: B

Rationale: The correct answer is to determine the client’s daily caloric intake first. This step is crucial in understanding the client's current dietary habits and establishing a baseline for creating an effective weight loss plan. Educating the client about daily caloric requirements (Choice A) can only be done effectively after knowing the client's current intake. Providing meal planning information (Choice C) and teaching the client how to identify fat content in foods (Choice D) come after determining the baseline caloric intake to tailor the plan accordingly.

4. 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.

5. Earliest sign of skin reaction to radiation therapy is:

A. desquamation
B. erythema
C. atrophy
D. pigmentation

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.
