Nursing Elites

1. 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.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

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: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

3. When providing perineal care to a female client, how should the nurse perform the procedure?

• A. with gloves, washing the perineal area from front to back
• B. without gloves, having the client perform all care
• C. with gloves, washing the perineal area from back to front
• D. without gloves, pouring water from a sterile bottle

Correct answer: A

Rationale: When providing perineal care to a female client, the nurse should wear gloves and wash the perineal area from front to back. This technique helps prevent the introduction of E. coli and other bacteria into the urethra, reducing the risk of urinary tract infections. Washing from back to front can introduce bacteria from the anal area to the urethra, leading to infections. Performing the procedure without gloves or having the client perform all care does not adhere to infection control practices. Pouring water from a sterile bottle alone may not ensure proper cleansing and infection prevention. Therefore, choices B, C, and D are incorrect as they do not follow proper perineal care guidelines.

4. What is a common side effect of Rifampin concerning the client's contact lenses?

• A. The client's urine might turn blue.
• B. The client remains infectious to others for 48 hours.
• C. The client's contact lenses might be stained orange.
• D. The client's skin might take on a crimson glow.

Correct answer: C

Rationale: The correct answer is that the client's contact lenses might be stained orange. Rifampin has the unusual effect of turning body fluids an orange color. Soft contact lenses might become permanently stained, making this an important side effect for the client to be aware of. Choices A, B, and D are incorrect. There is no documented effect of Rifampin causing the client's urine to turn blue, the client remaining infectious for 48 hours, or the client's skin taking on a crimson glow.

5. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.
