Nursing Elites

1. 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.

2. One of the complications of complete bed rest and immobility is which of the following?

• A. Plantar flexion
• B. Dorsiflexion
• C. Extension contractures
• D. Adduction contractures

Correct answer: A

Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.

3. Which of the following is an example of intrapersonal conflict?

• A. A nurse feels guilty when she administers essential medication that causes a client to have nausea and vomiting
• B. A nurse is called to testify in court about a client she cared for three years ago
• C. A nurse feels guilty for working overtime
• D. A nurse faces a conflict with a colleague over patient care decisions

Correct answer: A

Rationale: Intrapersonal conflict involves negative feelings or frustrations within oneself. It may be related to decisions or actions that clash with personal morals or beliefs. Choice A is the correct answer because the nurse is experiencing guilt due to administering medication that causes a client to have negative side effects, which reflects an internal struggle. Choices B, C, and D do not represent intrapersonal conflict. Choice B involves a legal obligation, Choice C is related to external factors like working overtime, and Choice D pertains to a conflict with a colleague.

4. 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.

5. The nurse is speaking at a community meeting about personal responsibility for health promotion. A participant asks about chiropractic treatment for illnesses. What should be the focus of the nurse's response?

• A. Electrical energy fields
• B. Spinal column manipulation
• C. Mind-body balance
• D. Exercise of joints

Correct answer: B

Rationale: The focus of the nurse's response should be on spinal column manipulation when discussing chiropractic treatment for illnesses. Chiropractic theory emphasizes that misalignment of the vertebrae can interfere with the transmission of mental impulses between the brain and body organs, leading to diseases. Manipulation is aimed at reducing such misalignments, known as subluxations. While mind-body balance and exercise of joints are important aspects of holistic health, in the context of chiropractic treatment, the key intervention is spinal column manipulation to address vertebral misalignments. Therefore, choices A, C, and D are incorrect as they do not directly address the primary focus of chiropractic treatment.
