Nursing Elites

1. 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.

2. Which task should not be performed by the licensed practical nurse?

• A. Inserting a Foley catheter
• B. Discontinuing a nasogastric tube
• C. Obtaining a sputum specimen
• D. Initiating a blood transfusion

Correct answer: D

Rationale: A licensed practical nurse should not initiate a blood transfusion. LPNs can assist with transfusions and verify ID numbers but should not be assigned to initiate the procedure. Inserting Foley catheters, discontinuing nasogastric tubes, and obtaining sputum specimens are within the scope of practice for LPNs. Therefore, options A, B, and C are tasks that LPNs can perform, making them incorrect choices.

3. Support-system enhancement includes all of the following except:

• A. determining the barriers to using support systems.
• B. discussing ways to help others who are concerned.
• C. exploring life problems of the support-team members.
• D. involving spouse, family, and friends in the care and planning.

Correct answer: C

Rationale: Support-system enhancement involves various strategies to strengthen the support system. Determining the barriers to using support systems, discussing ways to help others who are concerned, and involving spouse, family, and friends in the care and planning are all essential aspects of enhancing the support system. However, exploring the life problems of the support-team members is not directly related to enhancing the support system. This approach could potentially invade personal boundaries and may not be necessary for improving the support system, making it the correct answer in this case. Therefore, option C is the correct answer as it does not align with the appropriate methods of support-system enhancement.

4. A twenty-one-year-old man suffered a concussion, and the MD ordered an MRI. The patient asks, 'Will they allow me to sit up during the MRI?' The correct response by the nurse should be:

• A. "I will have to talk to the doctor about letting you sit upright during the test."?
• B. "You will be positioned in the reverse Trendelenburg position to maximize the view of the brain."?
• C. "The radiologist will let you know."?
• D. "You will have to lie down on your back during the test."?

Correct answer: D

Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain. Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test. Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans. Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.

5. Activities of effective supervisors can be task-related or people-related activities. An example of a task-related supervisory activity is:

• A. coaching.
• B. evaluating.
• C. delegating.
• D. facilitating.

Correct answer: C

Rationale: Delegating is the act of assigning work to those capable and competent to do the work, making it a task-related supervisory activity. Coaching, evaluating, and facilitating are people-related supervisory activities. Coaching involves guiding and developing individuals, evaluating entails assessing performance, and facilitating focuses on enabling tasks and processes. These activities are more centered on interacting with and supporting people rather than directly assigning tasks. Therefore, in the context of task-related activities, delegating stands out as the correct choice.
