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. 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.

3. An advance directive is written and notarized according to law in the state of Colorado. This document is legal and binding:

• A. internationally.
• B. in the state of Colorado only.
• C. in the continental United States.
• D. in the county of origination only.

Correct answer: B

Rationale: The correct answer is 'in the state of Colorado only.' Advance directive protocols and documents are specific to each state's laws and regulations. Choice A is incorrect as advance directives are not universally recognized internationally. Choice C is incorrect as the legal validity of an advance directive is limited to the state in which it was created. Choice D is incorrect as the legal reach of an advance directive typically extends throughout the state of origination, not just the county.

4. A client with cancer is transported to the radiology department for a bone scan to determine whether the cancer has metastasized to bone. While the client is in the radiology department, the client's wife arrives for a visit and asks what test is being performed on the client. What should the nurse tell the wife?

• A. A bone scan is being performed.
• B. She can read the client's medical record to determine what the health care provider prescribed.
• C. The radiology department is not clear as to which test has been prescribed.
• D. She will have to discuss the prescribed test with the client.

Correct answer: D

Rationale: In healthcare, confidentiality is crucial. Without the client's consent, nurses cannot disclose confidential information to anyone else, even to family members. Therefore, the appropriate response is to inform the client's wife that she will have to discuss the test with the client directly. It is not appropriate to disclose sensitive medical information without the client's permission. Offering the wife to read the medical record is a violation of privacy and confidentiality. Indicating that the radiology department is unclear about the prescribed test is inaccurate and does not uphold confidentiality. Moreover, it is not the responsibility of another department to disclose medical information; it is the duty of the healthcare provider and the client to discuss such matters.

5. Following a recent tattoo, someone should be screened for:

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

Correct answer: C

Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.
