1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. Which of the following foods might a client with hypercholesterolemia need to decrease intake of?

• A. broiled catfish
• B. hamburgers
• C. wheat bread
• D. fresh apples

Correct answer: B

Rationale: A client with hypercholesterolemia should decrease their intake of foods high in cholesterol. Hamburgers, being red meat, have a high cholesterol content, hence should be decreased in the diet. Broiled catfish, wheat bread, and fresh apples are not high in cholesterol, so there is no need to decrease their intake. Broiled catfish is a lean source of protein, wheat bread is a complex carbohydrate, and fresh apples are a good source of fiber and vitamins. Therefore, hamburgers are the correct choice to decrease intake for a client with hypercholesterolemia.

3. What is the 24-hour day-night cycle known as?

• A. circadian rhythm
• B. infradian rhythm
• C. ultradian rhythm
• D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

4. During an emergency procedure, is the surgical timeout a requirement?

• A. The surgical timeout should be performed by the surgical team unless it would cause a delay leading to injury or death.
• B. No, the timeout is not necessary during an emergency procedure.
• C. No, the surgical timeout is not required in emergency procedures.
• D. Yes, the surgical timeout must be performed in all cases.

Correct answer: A

Rationale: During an emergency procedure, the surgical timeout should be performed unless doing so would cause a delay leading to injury or death. This is because the primary goal during an emergency is to swiftly address the critical situation. Choice B is incorrect as it implies that the timeout is not necessary, which is not accurate. Choice C is also incorrect as it suggests that the timeout is not required in emergency procedures, disregarding safety protocols. Choice D is incorrect as it wrongly states that the timeout must be performed in all cases without considering the potential risks associated with delays during emergencies.

5. As part of the teaching plan for a client with type I diabetes mellitus, the nurse should include that carbohydrate needs might increase when:

• A. an infection is present.
• B. there is an emotional upset.
• C. a large meal is eaten.
• D. active exercise is performed.

Correct answer: D

Rationale: During active exercise, insulin sensitivity increases, leading to lower blood glucose levels. To balance the effect of increased insulin sensitivity, additional carbohydrates might be needed. The other choices are incorrect because: A) an infection typically raises blood glucose levels rather than increasing the need for carbohydrates; B) emotional upset can impact blood glucose but does not directly affect carbohydrate needs; C) while a large meal can raise blood glucose levels, it does not necessarily mean an increase in carbohydrate needs.
