Nursing Elites

1. Which task would be appropriate for the LPN to perform?

• A. Changing a colostomy bag.
• B. Hanging a new bag of TPN.
• C. Drawing a peak antibiotic blood level from a central line.
• D. Administering IV pain medication to a two-day post-op client.

Correct answer: A

Rationale: The correct answer is changing a colostomy bag. This task falls within the LPN's scope of practice. LPNs are trained to provide basic nursing care, including assisting with activities of daily living and certain medical procedures like changing ostomy bags. Hanging a new bag of TPN and drawing a peak antibiotic blood level from a central line are tasks that require a higher level of training and are typically performed by RNs due to their complexity and potential risks. Administering IV pain medication to a two-day post-op client is usually the responsibility of an RN as it involves close monitoring, assessment of the client's condition, and the administration of potent medications that require a higher level of clinical judgment and expertise.

2. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:

• A. a maintenance dose.
• B. a loading dose.
• C. a medication with no first-pass effect.
• D. the medication to be given intravenously.

Correct answer: B

Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.

3. The client diagnosed with end-stage liver disease has completed an advance directive and a do-not-resuscitate (DNR) document and wishes to receive palliative care. Which of the following would correspond to the client's wish for comfort care?

• A. Positioning frequently to prevent skin breakdown and providing pain management and other comfort measures
• B. Carrying out vigorous resuscitation efforts if the client were to stop breathing, but no resuscitation if the heart stops beating
• C. Providing intravenous fluids when the client becomes dehydrated
• D. Providing total parenteral nutrition (TPN) if the client is not able to eat

Correct answer: A

Rationale: Palliative care includes measures to prevent skin breakdown, pain management, and management of other symptoms that cause discomfort, as well as encouraging contact with family and friends. A DNR request precludes all resuscitative efforts related to respiratory or cardiac arrest, making choice B incorrect. Dehydration is a natural part of the dying process, so providing intravenous fluids as in choice C would not align with the client's wish for comfort care. Total parenteral nutrition (TPN) as in choice D is an invasive procedure meant to prolong life and is not part of palliative care, which focuses on improving quality of life rather than extending it.

4. Which statement best describes electrolytes in intracellular and extracellular fluid?

• A. There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid
• B. There is an equal concentration of sodium and potassium in extracellular fluid
• C. There is a greater concentration of potassium in extracellular fluid and sodium in intracellular fluid
• D. There is an equal concentration of sodium and potassium between intracellular and extracellular fluid

Correct answer: A

Rationale: Electrolytes are distributed unequally between intracellular and extracellular fluids. Sodium concentration is higher in extracellular fluid, while potassium concentration is higher in intracellular fluid. Therefore, the correct answer is 'There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid.' Choices B, C, and D are incorrect because they do not accurately describe the typical distribution of sodium and potassium between intracellular and extracellular fluid.

5. Which reported symptom would indicate a client with Addison's disease has received too much fludrocortisone (Florinef) replacement?

• A. Oily skin and hair
• B. Weight gain of 6 pounds in one week
• C. Loss of muscle mass in arms and legs
• D. Increased blood glucose level

Correct answer: B

Rationale: Fludrocortisone (Florinef) replacement in Addison's disease involves mimicking aldosterone to retain sodium and water. This retention can lead to weight gain due to increased fluid retention. Rapid weight gain, such as 6 pounds in one week, is a concerning sign of excessive fluid retention, indicating a potential overdose of fludrocortisone. Choices A, C, and D are incorrect because oily skin and hair, loss of muscle mass, and increased blood glucose levels are not specific symptoms of excessive fludrocortisone replacement in Addison's disease.
