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. Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?

• A. Contractures.
• B. Constipation.
• C. Calcium loss.
• D. Catabolism.

Correct answer: C

Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.

3. A patient with bipolar disorder asks the nurse, "Why did I get this illness? I don't want to be sick."? The nurse would best respond with:

• A. People who develop mental illnesses often had a very traumatic childhood experience.
• B. There is some evidence that contracting a virus during childhood can lead to mental disorders.
• C. Sometimes people with mental illness have an overactive immune system.
• D. We don't fully understand the cause, but mental illnesses do seem to run in the family.

Correct answer: D

Rationale: The correct response is, 'We don't fully understand the cause, but mental illnesses do seem to run in the family.' Current research suggests that while genetics play a role in the development of mental illnesses like bipolar disorder, it is not the sole factor. Environmental influences, life experiences, and other non-genetic factors also contribute significantly to the manifestation of mental disorders. Choices A, B, and C provide incorrect information that is not supported by current research. Traumatic childhood experiences, contracting a virus during childhood, and an overactive immune system are not established causes of bipolar disorder or mental illnesses in general.

4. The key to the prevention of a pandemic influenza is:

• A. Early detection
• B. Early antibiotic treatment
• C. Vaccination of at-risk populations
• D. Isolation of suspected cases

Correct answer: A

Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.

5. Which of the following is an example of libel?

• A. A client overhears a nurse telling her assistant that he is 'too high maintenance.'
• B. A client reads disparaging remarks that a nurse has written about him in his chart.
• C. A nurse fails to notify a physician when a client's hemoglobin level is 8.1 gm/dL.
• D. A nurse administers narcotic pain medication to a client in pain but does not have an order.

Correct answer: B

Rationale: Libel involves making defamatory statements against another person in written form. These statements can harm the person's reputation or feelings. In this scenario, the correct answer is when a client reads disparaging remarks that a nurse has written about him in his chart. This constitutes libel because the negative remarks are written down and can potentially damage the client's reputation. Choices A, C, and D do not involve libel. Choice A describes a verbal statement, not written, so it does not constitute libel. Choice C involves a failure to notify a physician, which is a different issue unrelated to libel. Choice D pertains to administering medication without an order, which is a matter of improper practice rather than libel.
