1. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

A. CPK-BB
B. CPK-MM
C. CPK-MB
D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

2. What is the appropriate intervention for a client who is restrained?

A. Remove the restraints and provide skin care every hour.
B. Document the condition of the client's skin every 3 hours.
C. Assess the restraint every 30 minutes
D. Tie the restraint to the side rails.

Correct answer: C

Rationale: The correct intervention when a client is restrained is to assess the restraint every 30 minutes. This ensures the safety and well-being of the client by checking for proper fit, circulation, and signs of distress. Removing restraints and providing skin care every hour may not be necessary and could increase the risk of skin breakdown. Documenting the skin condition every 3 hours is important but not the immediate intervention needed when a client is restrained. Tying the restraint to the side rails is unsafe and can cause harm to the client, as restraints should be secured to the bed frame or an immovable part of the bed.

3. What is the role of an incident report in risk management?

A. To provide liability protection.
B. To provide data for analysis by a risk manager to determine how future problems can be avoided.
C. To discipline staff for errors.
D. All of the above.

Correct answer: B

Rationale: The correct answer is B. Incident reports play a crucial role in risk management by providing data for analysis to prevent future problems. They are not primarily for liability protection (A) or disciplining staff (C). Therefore, choice B is the most appropriate answer. Choosing option D is incorrect because incident reports do not solely exist for all the mentioned purposes, but primarily to provide data for analysis and preventive actions.

4. A client with a nasogastric (NG) tube begins vomiting. What action should the nurse take?

A. Retape the NG tube.
B. Clamp the NG tube.
C. Remove the NG tube.
D. Check the NG tube placement.

Correct answer: D

Rationale: When a client with a nasogastric (NG) tube begins vomiting, the nurse should first check the NG tube placement. Vomiting can be a sign of tube displacement, which can lead to serious complications. Retaping the tube (Choice A), clamping it (Choice B), or removing it (Choice C) without first assessing its placement can be harmful or ineffective. Checking the NG tube placement is crucial as it ensures that the tube is in the correct position and prevents potential complications. Retaping the NG tube (Choice A) is incorrect because the priority is to check the placement first. Clamping the NG tube (Choice B) or removing it (Choice C) without verifying the placement can be dangerous if the tube is dislodged. Thus, these actions should not be taken before confirming the tube's position.

5. An LPN is working on the care plan for a client with diabetes mellitus. Which of these outcomes would be the most appropriate?

A. The client will maintain a blood glucose level within the normal range of 70-110 (per facility policy) throughout my shift.
B. The client will maintain a blood glucose level within normal range limits today.
C. The client will maintain a blood glucose level within the normal range of 70-110 (per facility policy) throughout my shift.
D. The client will maintain a blood glucose level within normal limits throughout my shift.

Correct answer: C

Rationale: The correct answer is 'The client will maintain a blood glucose level within the normal range of 70-110 (per facility policy) throughout my shift.' This outcome is specific, measurable, and aligns with the goal of managing diabetes mellitus. Choice A is correct because it provides a clear target range (70-110) and includes adherence to facility policy, making it precise and goal-oriented. Choice B lacks specificity on the timeframe, and Choice D is vague in defining the target blood glucose range. In nursing care plans, outcomes should be well-defined, achievable, and measurable to effectively monitor the client's progress in managing their condition.
