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. An example of a process standard on a med-surg unit is:

A. a procedure for changing IV tubing.
B. a policy for staffing.
C. the job description of the CEO (chief executive officer).
D. a procedure for checking waveforms on a client being treated with an intra-aortic balloon pump.

Correct answer: D

Rationale: Process standards define the actions and behaviors required by staff to provide care on a med-surg unit. A procedure for changing IV tubing is a critical psychomotor skill necessary for safe and effective patient care in this setting. Choice B, a policy for staffing, pertains more to organizational management rather than specific care processes on the unit. Choice C, the job description of the CEO, delineates the responsibilities of the organization's top executive and is not a process standard for frontline staff. Choice D, a procedure for checking waveforms on a client with an intra-aortic balloon pump, is more specific to a cardiac care unit and not typically performed on a med-surg unit.

3. What spinal change occurring with pregnancy alters mobility?

A. Scoliosis.
B. Kyphosis.
C. Lordosis.
D. Ankylosing spondylitis.

Correct answer: C

Rationale: The correct answer is 'Lordosis.' During pregnancy, the enlarging uterus places increased weight on the spine, causing an exaggerated inward curvature known as lordosis. This change alters mobility by shifting the center of gravity forward, leading to a compensatory change in posture. Scoliosis (choice A) is a sideways curvature of the spine, not typically associated with pregnancy. Kyphosis (choice B) is an exaggerated outward curvature of the spine, while ankylosing spondylitis (choice D) is a chronic inflammatory condition affecting the spine, neither of which are directly related to the spinal changes seen in pregnancy.

4. A licensed practical nurse (LPN) works on an adult medical/surgical unit and has been pulled to work on the burn unit, which cares for clients of all ages. What should the LPN do?

A. The LPN should take the assignment, but make it clear they will only care for adult clients.
B. The LPN should take the assignment, but explain the situation to the charge nurse and ask for a quick orientation before starting.
C. The LPN should refuse to take the assignment, as caring for the infant and child population is not within their scope of practice.
D. The LPN should take the assignment, but ask to be paired with a more experienced LPN.

Correct answer: B

Rationale: In this scenario, it is crucial for the LPN to demonstrate flexibility and a willingness to adapt to the new assignment that involves caring for clients of all ages. While the LPN may have expertise in a specific nursing area, it is essential to be able to provide care to diverse client populations. Accepting the assignment reflects a commitment to teamwork and patient care. However, to ensure safe and competent care, the LPN should communicate with the charge nurse about the situation. Requesting a quick orientation will help the LPN familiarize themselves with the burn unit's specific requirements, equipment, and protocols. This proactive approach allows the LPN to address any concerns, ask questions, and seek necessary support, ultimately ensuring the best care for all clients in the burn unit. Choice A is incorrect because limiting care to only adult clients may not be feasible in a unit that cares for clients of all ages. Choice C is incorrect as refusing the assignment outright may not be the best approach without considering alternatives. Choice D is not the most effective option as asking to be paired with a more experienced LPN does not address the need for a quick orientation to the new unit.

5. A nurse working the 7 a.m. to 3 p.m. shift is reviewing the records of the assigned clients. Which client should the nurse assess first?

A. A client scheduled for hemodialysis at 10 a.m.
B. A client scheduled for contrast computed tomography (CT) at noon.
C. A client scheduled for a nuclear scanning procedure at 10 a.m.
D. A client scheduled for hydrotherapy for the treatment of a burn injury at 10:30 a.m.

Correct answer: A

Rationale: The correct answer is the client scheduled for hemodialysis at 10 a.m. This client needs immediate assessment before the procedure, which may take up to 5 hours. The nurse should ensure the client is physically and emotionally prepared, check for fluid overload by assessing weight and lung sounds, review vital signs, and laboratory test results. The other clients described in the options have needs that are not as urgent. The client scheduled for a nuclear scanning procedure at 10 a.m. may require information reinforcement and increased fluid intake before the procedure. The client scheduled for hydrotherapy for the treatment of a burn injury at 10:30 a.m. may need pain medication administered 30 minutes prior to the therapy. The client scheduled for a contrast CT at noon may need procedure information reinforcement and a special contrast preparation just before the procedure.
