Nursing Elites

1. Who may legally give informed consent?

• A. an 86-year-old male with advanced Alzheimer's disease
• B. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• C. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• D. a 6-month-old baby needing bowel surgery

Correct answer: C

Rationale: The correct answer is a 14-year-old girl needing an appendectomy who is not an emancipated minor. Informed consent can be given by individuals who are competent and not minors. Minors are generally unable to provide informed consent unless they are emancipated. Choice A is incorrect because an 86-year-old male with advanced Alzheimer's disease is considered incompetent to make decisions. Choice D is incorrect because a 6-month-old baby is unable to provide consent. Emancipated minors are an exception to the minor rule, as they can provide consent for their own treatment.

2. A client is taking hydrocodone (Vicodin) for chronic back pain. The client has required an increase in the dose and asks whether this means he is addicted to Vicodin. The nurse should base her reply on the knowledge that:

• A. the client's body has developed tolerance, requiring more drug to produce the same effect
• B. the client is preoccupied with getting the drug and is experiencing loss of control, indicating drug dependence
• C. addiction involves psychological behaviors related to substance use, not just physical dependence
• D. the client is coping with chronic back pain and requires adjustments in the medication regimen

Correct answer: A

Rationale: When a client requires an increased dose of a drug, such as in this case with hydrocodone, it suggests that the body has developed tolerance to the medication. Tolerance means that the client needs more of the drug to achieve the same effect as before. This does not inherently indicate addiction, which involves psychological behaviors related to substance use. Choice B describes drug dependence, where the client is preoccupied with obtaining the drug and experiences loss of control, which is not the same as tolerance. Choice C correctly points out that addiction is more than just physical dependence with withdrawal symptoms and tolerance; it includes psychological factors. Choice D is irrelevant as it discusses adjusting the medication for pain management, not addressing the client's concern about addiction.

3. The physician has ordered a culture for the client with suspected gonorrhea. The nurse should obtain which type of culture?

• A. Blood
• B. Nasopharyngeal secretions
• C. Stool
• D. Genital secretions

Correct answer: D

Rationale: A culture for gonorrhea is taken from the genital secretions as gonorrhea primarily affects the genital area. The culture is incubated in a warm environment to promote the growth of Neisseria gonorrhoeae, the bacterium causing gonorrhea. Genital secretions provide a direct sample from the site of infection, increasing the accuracy of diagnosis. Choices A, B, and C are incorrect as they are not suitable specimens for diagnosing gonorrhea. Blood cultures are used to detect bloodstream infections, nasopharyngeal secretions are collected for respiratory infections, and stool cultures are done to identify gastrointestinal infections, none of which are related to gonorrhea.

4. The nurse is making assignments for the day. Which client should be assigned to the nursing assistant?

• A. A client with Alzheimer's disease
• B. A client with pneumonia
• C. A client with appendicitis
• D. A client with thrombophlebitis

Correct answer: A

Rationale: The client with Alzheimer's disease is the most stable among the clients listed and can be appropriately assigned to the nursing assistant. Nursing assistants are capable of providing care such as feeding and assisting with activities of daily living for individuals with Alzheimer's disease. Clients with pneumonia, appendicitis, and thrombophlebitis are less stable and necessitate the expertise of a registered nurse for accurate assessment and interventions. Therefore, the nursing assistant can effectively care for the client with Alzheimer's disease while ensuring that the other clients receive the necessary level of care from a registered nurse.

5. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.
