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. Mr. Freeman has difficulty getting out of bed. The nurse should encourage Mr. Freeman to ______________.

• A. ask for assistance before getting out of bed.
• B. remain in bed because it is safer and he will not fall.
• C. instruct him to stand up quickly from the bed.
• D. lean forward and push up and off the bed.

Correct answer: A

Rationale: The nurse should encourage Mr. Freeman to use his call bell and ask for assistance before getting out of bed. This can prevent him from falling. Patients should not stay in bed; they should be encouraged to get out of bed as much as possible to prevent complications like pressure ulcers and muscle weakness. Instructing a patient to stand up quickly from the bed is unsafe as it can lead to dizziness and falls. Similarly, leaning forward and pushing off the bed can increase the risk of falls and should be avoided. Asking for assistance is the safest and most appropriate option to ensure patient safety and prevent accidents.

3. 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.

4. The clinic nurse teaches a patient with a 42 pack-year history of cigarette smoking about lung disease. Which information will be most important for the nurse to include?

• A. Options for smoking cessation
• B. Reasons for annual sputum cytology testing
• C. Erlotinib (Tarceva) therapy to prevent tumor risk
• D. Computed tomography (CT) screening for lung cancer

Correct answer: A

Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.

5. 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.
