1. Which of the following HDL cholesterol levels might warrant regular testing?

A. 70 or higher
B. 60
C. 50
D. 40

Correct answer: A

Rationale: An HDL cholesterol level of 70 or higher is considered high and beneficial for heart health. Individuals with high HDL levels are usually at lower risk of heart disease. Therefore, a level of 70 or above would warrant regular testing to monitor and maintain heart health. Choices B, C, and D are lower levels of HDL cholesterol, which are not typically considered high enough to warrant regular testing as they may not provide the same level of heart health benefits.

2. When evaluating the reliability of a patient's responses, which of these statements would be correct? The patient:

A. has a history of drug abuse and therefore is not reliable.
B. provided consistent information and therefore is reliable.
C. smiled throughout the interview and therefore is assumed reliable.
D. would not answer questions concerning stress and therefore is not reliable.

Correct answer: B

Rationale: In evaluating the reliability of a patient's responses, consistency in the information provided by the patient is crucial. When a patient provides consistent information, it indicates that their responses are trustworthy and reliable. In this scenario, the nurse can consider the patient as reliable based on the consistency of the information provided. Other factors such as a history of drug abuse, smiling behavior, or refusal to answer certain questions may not necessarily determine the reliability of the patient's responses. Therefore, the correct choice is B as consistency in responses is a more reliable indicator of trustworthiness than other factors mentioned in the choices.

3. What is the name of the outermost layer of the skin?

A. dermis
B. epidermis
C. subcutaneous tissue
D. hypodermis

Correct answer: B

Rationale: The epidermis is the correct answer as it is the outermost layer of the skin. It acts as a protective barrier against environmental factors and helps in regulating moisture balance. The epidermis is also where new skin cells are continuously formed and contains melanocytes responsible for skin pigmentation. Choices A, C, and D are incorrect. The dermis is the layer beneath the epidermis, the subcutaneous tissue is the deepest layer of the skin, and the hypodermis lies below the dermis.

4. What does 'Deficit' mean?

A. An excess of something
B. A deficiency or lack of something
C. An abundance of something
D. A stable amount

Correct answer: B

Rationale: The correct answer is B: 'A deficiency or lack of something.' The term 'deficit' refers to a shortage or inadequacy of something. Choice A is incorrect because a surplus means an excess, which is the opposite of a deficit. Choice C is incorrect as an abundance signifies a large quantity or more than enough of something. Choice D is incorrect as a stable amount does not convey the concept of a deficit.
