Nursing Elites

1. The nurse teaching a client about hepatitis and its transmission should explain that one type of hepatitis does not produce a carrier state after its acute phase. Which type is it?

• A. hepatitis A
• B. hepatitis B
• C. hepatitis C
• D. hepatitis D

Correct answer: A

Rationale: The correct answer is hepatitis A. Hepatitis A does not produce a carrier state after its acute phase. It is transmitted via contaminated water or food through the oral-fecal route and is not blood-borne. Hepatitis B, choice B, can lead to a carrier state where the person remains infectious despite being asymptomatic. Hepatitis C, choice C, can also result in a chronic carrier state. Hepatitis D, choice D, is an incomplete virus that requires hepatitis B to replicate; it does not lead to a carrier state on its own.

2. 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.

3. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

4. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

• A. 2 liters/minute
• B. 4 liters/minute
• C. 6 liters/minute
• D. 8 liters/minute

Correct answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

5. When should the biohazard emblem be affixed to containers according to the orientation nurse educator reviewing the biohazard legend with a class of new employees?

• A. when there is presence of blood and body fluids.
• B. when there is the need for droplet precautions.
• C. when there is contact isolation.
• D. when there is the potential for airborne transmission.

Correct answer: A

Rationale: The correct answer is 'when there is presence of blood and body fluids.' When handling body substances like blood and body fluids, the risk of transmission of infections increases. Federal regulations mandate warning labels on containers to alert employees and waste collectors. The biohazard emblem consists of a three-ring symbol overlaying a central concentric ring. Blood, wound drainage, feces, and urine are examples of body fluids that can transmit infections and diseases to others. The other choices, B, C, and D, are incorrect because the presence of the biohazard emblem is specifically linked to the handling of blood and body fluids, not to droplet precautions, contact isolation, or airborne transmission.
