1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. Pulling is easier than pushing. So pulling a client rather than pushing them has which of the following advantages?

• A. reduces workload
• B. decreases opposition from gravity
• C. maintains stability
• D. prevents muscle strain

Correct answer: A

Rationale: When pulling a client, you work with the gravitational force instead of opposing it, which reduces the workload on your muscles. Choosing to pull a client minimizes the effort required compared to pushing. Choice B is incorrect because the force of gravity remains constant regardless of pushing or pulling. Choice C is irrelevant as stability is not directly related to the advantage of pulling over pushing. Choice D is inaccurate because pulling can still strain muscles if not executed correctly, but it generally reduces the overall workload in comparison to pushing.

3. What information does the healthcare provider remember regarding do-not-resuscitate (DNR) orders in this scenario?

• A. That a DNR order may be written by a healthcare provider
• B. That everything possible must be done if the client stops breathing
• C. That medications only may be given to the client if the client stops breathing
• D. That life support measures will have to be implemented if the client stops breathing

Correct answer: A

Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.

4. The client has a new prosthetic hip, and the nurse is repositioning them. Which position should be avoided to prevent injury to the new prosthetic hip?

• A. abduction of the hip
• B. adduction of the hip
• C. flexing the hip at 80� flexion
• D. flexing the hip at 90�

Correct answer: B

Rationale: The correct answer is 'adduction of the hip.' When a client has a new prosthetic hip, adduction (movement of the leg toward the midline of the body) should be avoided to prevent injury to the new prosthetic hip. Abduction (movement of the leg away from the midline) is typically allowed and may even be encouraged. Flexing the hip at certain degrees is acceptable, but adduction should be avoided to prevent complications or dislocation of the prosthetic hip. Therefore, options A, C, and D are incorrect because they do not pose a direct risk to the new prosthetic hip compared to adduction.

5. A safety measure to implement when transferring a client with hemiparesis from a bed to a wheelchair is:

• A. standing the client and walking him or her to the wheelchair.
• B. moving the wheelchair close to the client's bed and standing and pivoting the client on his unaffected extremity to the wheelchair.
• C. moving the wheelchair close to the client's bed and standing and pivoting the client on his affected extremity to the wheelchair.
• D. having the client stand and push his body to the wheelchair.

Correct answer: B

Rationale: When transferring a client with hemiparesis from a bed to a wheelchair, it is crucial to ensure their safety. The correct safety measure involves moving the wheelchair close to the client's bed and having the client stand and pivot on his unaffected extremity to the wheelchair. This method provides support with the unaffected limb, reducing the risk of falls and promoting a safer transfer. Choice A is incorrect because walking the client is unsafe and not recommended. Choice C is incorrect as pivoting the client on his affected extremity can lead to injury or falls due to weakness or lack of control. Choice D is incorrect as it puts the client at risk by requiring them to push their body, which may not be feasible or safe for someone with hemiparesis.
