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. What kind of preventive measures is MOST likely to be used to prevent Mary Eden from falling due to her muscular frailty?

• A. Physical therapy for muscle strengthening exercises
• B. Physical therapy for range of motion exercises
• C. Occupational therapy to help her with confusion
• D. Medications to help her sleep more

Correct answer: A

Rationale: Mary Eden, due to her muscular frailty, is at risk of falling. The most effective preventive measure in this case would be physical therapy focusing on muscle strengthening exercises. Strengthening exercises can help improve her muscle tone and stability, reducing the risk of falls. While range of motion exercises may be beneficial, they may not directly address her muscular frailty and stability concerns as effectively as muscle strengthening exercises. Occupational therapy aims to help individuals with activities of daily living and functional tasks, not confusion. Medications to induce more sleep can actually increase the risk of falls due to potential side effects like dizziness or disorientation, rather than preventing falls.

3. While planning care for a toddler, the nurse teaches the parents about the expected developmental changes for this age. Which statement by the mother shows that she understands the child's developmental needs?

• A. "I want to protect my child from any falls."?
• B. "I will set limits on exploring the house."?
• C. "I understand the need to use those new skills."?
• D. "I intend to keep control over our child."?

Correct answer: C

Rationale: The correct answer is: "I understand the need to use those new skills."? This response indicates that the mother recognizes the importance of allowing the toddler to practice and develop new skills, supporting autonomy and exploration. Setting limits, protecting from falls, and intending to keep control go against the toddler's developmental needs. Toddlers at this stage require opportunities to explore, practice new skills, and gain independence to foster healthy development.

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. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?

• A. The Programmed Longevity Theory
• B. The Immunological Theory of Aging
• C. The Endocrine Theory
• D. The Rate of Living Theory

Correct answer: B

Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.
