1. In which order will the nurse take these steps to prepare NPH 20 units and regular insulin 2 units using the same syringe? (Put a comma and a space between each answer choice [A, B, C, D, E]).

• A. Rotate NPH vial, Inject 20 units of air into NPH vial, Withdraw regular insulin, Inject 2 units of air into regular insulin vial, Withdraw 20 units of NPH.
• B. Rotate NPH vial, Inject 20 units of air into NPH vial, Withdraw regular insulin, Inject 2 units of air into regular insulin vial, Withdraw 20 units of NPH.
• C. Rotate NPH vial, Inject 20 units of air into NPH vial, Inject 2 units of air into regular insulin vial, Withdraw regular insulin, Withdraw 20 units of NPH.
• D. Rotate NPH vial, Inject 20 units of air into NPH vial, Withdraw 20 units of NPH, Inject 2 units of air into regular insulin vial, Withdraw regular insulin.

Correct answer: C

Rationale: The correct order to prepare NPH 20 units and regular insulin 2 units using the same syringe is to start by rotating the NPH vial, then injecting 20 units of air into the NPH vial. Next, inject 2 units of air into the regular insulin vial, followed by withdrawing the regular insulin. Finally, withdraw 20 units of NPH. This sequence ensures proper mixing and preparation of the insulin doses. Choices A, B, and D have incorrect sequences that may lead to incorrect dosages or inadequate mixing of the insulins.

2. The staff nurse delegates AM care for two patients to the UAP (Unlicensed Assistive Person). What principle of delegation is the nurse following?

• A. Delegation requires a situation with clearly defined superiors.
• B. Delegation can only exist with a subordinate.
• C. Delegation is a tool used by various healthcare professionals.
• D. You can delegate only those tasks.

Correct answer: D

Rationale: The correct answer is D: 'You can delegate only those tasks.' Delegation in nursing involves transferring responsibility for the performance of a task while retaining accountability for the outcome. The principle of delegation does not require a situation with clearly defined superiors (choice A). Delegation can exist not only with a subordinate but also with colleagues or other healthcare team members (choice B). Delegation is not exclusive to nurses and is a tool used by various healthcare professionals (choice C). Therefore, the best choice is D as it accurately reflects the principle of delegation in nursing.

3. A staff nurse is working with a patient who is on a critical pathway for education in preparation for home care. Which one of the following responsibilities would the nurse address first?

• A. Taking vital signs
• B. Answering the client's questions
• C. Evaluating client teaching
• D. Reviewing the information with the client and family

Correct answer: D

Rationale: The correct answer is D. Reviewing the information with the client and family should be addressed first. This step involves ensuring that the client and family fully understand the information provided, which is crucial before proceeding with any other responsibilities. Taking vital signs (choice A) is important but not the priority in this scenario. Answering the client's questions (choice B) and evaluating client teaching (choice C) can come after reviewing the information to ensure effective communication and understanding.

4. Which of the following theories best describes current health care delivery systems?

• A. Open system theory
• B. Closed system theory
• C. Chaos theory
• D. Contingency theory

Correct answer: D

Rationale: The contingency theory best describes the current health care delivery systems. Contingency theory emphasizes that there is no one best way to organize or manage, and the effectiveness of an organization is contingent upon internal and external factors. In healthcare, the delivery systems must often adapt and be flexible in response to various factors like patient needs, technological advancements, and regulatory changes. Open system theory focuses on the interaction between a system and its environment, but it does not capture the dynamic and adaptive nature of current healthcare systems. Closed system theory suggests systems are self-contained and do not interact with the environment, which is not accurate for healthcare systems that constantly interact with patients, providers, and external factors. Chaos theory deals with complex systems and unpredictability, which while relevant to some aspects of healthcare, does not provide a comprehensive framework for understanding healthcare delivery systems.

5. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?

• A. Position the client in a side-lying position.
• B. Perform the irrigation using a 20-mL syringe.
• C. Instill 15 mL of irrigation fluid into the catheter with each flush.
• D. Measure and record the amount of irrigant used.

Correct answer: B

Rationale: When irrigating an indwelling urinary catheter, the nurse should use a 20-mL syringe for the procedure. This syringe size helps to provide adequate pressure for effective irrigation. Placing the client in a side-lying position is not necessary for this procedure. Instilling a specific amount of irrigation fluid into the catheter is not mentioned in the scenario. Subtracting the amount of irrigant used from the client's urine output is not a standard practice in catheter irrigation.
