1. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

2. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

• A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
• B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
• C. The client should lie flat on their back for a specific period following the procedure.
• D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

3. Albert B. is incontinent of urine. He also wears glasses and hearing aids. His ____________lead(s) to his risk for falls.

• A. incontinence and loss of vision
• B. loss of vision
• C. incontinence
• D. loss of hearing

Correct answer: B

Rationale: Albert B. is at risk for falls due to two factors: his incontinence and his loss of vision. Loss of vision significantly impairs one's ability to navigate and avoid obstacles, thereby increasing the risk of falls. While incontinence is a risk factor for falls, the primary concern in this case is the loss of vision since it directly affects balance and safety. Therefore, the correct answer is 'loss of vision.' Choices A, C, and D are incorrect because they do not address the key factor of impaired vision leading to the risk of falls.

4. Which of these statements best describes the characteristics of an effective reward feedback system?

• A. Specific feedback is given as close to the event as possible
• B. Staff is given feedback in equal amounts over time
• C. Positive statements precede negative statements
• D. Performance goals should be higher than what is attainable

Correct answer: A

Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.

5. You are on the unit and overhear another nurse talking on the phone to a patient's friend who wants to see her patient who is comatose and on a ventilator. Since you cared for that patient yesterday, you know that the patient's significant other, who is also the designated healthcare surrogate (HCS) and has power of attorney (POA), has expressly stated that he wants this person on the list for restricted visitors. The nurse whispers that she'll call him to visit as soon as the significant other has gone home. What should your first response be?

• A. Inform the significant other
• B. Report the nurse to the nurse manager
• C. Speak with the nurse directly in private
• D. Call the visitor and tell him he can't visit

Correct answer: C

Rationale: Speaking with the nurse directly and privately is the most constructive manner in which to handle this situation and advocate for the significant other's wishes. Doing so will open communication with a peer and build the relationship, instead of alienating the other nurse by taking action that does not involve her and will cast her in a negative light with others. It is essential to express your concerns regarding honoring the significant other's requests and rights regarding the limitation of visitors. Option A is incorrect because the significant other is not the one trying to visit, and it is more appropriate to address the nurse directly first. Option B is not the best initial response as it may escalate the situation without giving the nurse a chance to correct the issue. Option D is incorrect as it does not address the issue at its source and may create further conflict without resolving the underlying problem.
