Nursing Elites

1. 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.

2. The client is being taught about the use of Rifampin for prophylaxis following exposure to meningitis. What change in bodily functions should the client be informed about?

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

Correct answer: C

Rationale: Rifampin has the unusual effect of turning body fluids an orange color. Soft contact lenses might become permanently stained. Clients should be taught about these side effects to avoid unnecessary concern. Option A is incorrect as Rifampin does not cause the urine to turn blue. Option B is incorrect as the client is not infectious to others due to taking Rifampin for prophylaxis. Option D is incorrect as Rifampin does not cause the skin to take on a crimson glow.

3. After receiving a recent tattoo, someone should be screened for:

• A. tuberculosis.
• B. herpes.
• C. hepatitis.
• D. syphilis.

Correct answer: C

Rationale: After receiving a recent tattoo, screening for hepatitis is crucial due to the risk of blood-borne hepatitis B or C if strict sterile procedures are not followed during the tattooing process. Tuberculosis is an airborne pathogen and is not directly related to receiving a tattoo. Herpes and syphilis are infections spread through direct contact, such as sexual contact, and are not typically associated with tattooing.

4. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

5. During a hospital program about in vitro fertilization, a television crew arrives to film for a series on hospital services. What action should the nurse conducting the program take?

• A. Ask the television crew to interview the individuals attending the program individually.
• B. Allow the television crew to videotape the program as long as they do not publicize that the program is about in vitro fertilization.
• C. Explain to the television crew that videotaping is not allowed.
• D. Allow the television crew to videotape the program.

Correct answer: C

Rationale: Privacy is a client's right to be free from unwanted intrusion into their private affairs. Videotaping constitutes an invasion of a client's privacy, and written permission is required from the client for actions such as photographing or videotaping. Therefore, the nurse must explain to the television crew that videotaping is not allowed to protect the attendees' privacy. Option A is incorrect as it still involves recording the individuals, breaching their privacy. Option B is incorrect because allowing videotaping without consent violates privacy rights. Option D is incorrect as it disregards the need for consent and privacy protection.
