Nursing Elites

1. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.

2. Which of the following types of antipsychotic medications is most likely to produce extrapyramidal effects?

• A. Atypical antipsychotic drugs
• B. First-generation antipsychotic drugs
• C. Third-generation antipsychotic drugs
• D. Dopamine system stabilizers

Correct answer: B

Rationale: The correct answer is first-generation antipsychotic drugs. These drugs are potent antagonists of D2, D3, and D4 receptors, making them effective in treating target symptoms but also leading to numerous extrapyramidal side effects due to the blockade of D2 receptors. Atypical or second-generation antipsychotic drugs, as mentioned in choice A, are relatively weak D2 blockers, which results in a lower incidence of extrapyramidal side effects. Third-generation antipsychotic drugs, as in choice C, and dopamine system stabilizers, as in choice D, are not typically associated with significant extrapyramidal effects compared to first-generation antipsychotics.

3. What is the purpose of performing quality control?

• A. Create a paper trail to show that the laboratory is compliant with OSHA standards for quality control.
• B. Improve the odds that the results reported for any given test are as accurate and reliable as possible.
• C. Be required by law to be part of a quality assurance program.
• D. All of the above

Correct answer: B

Rationale: The primary purpose of performing quality control is to enhance the accuracy and reliability of test results. Quality controls are crucial for ensuring the reliability of each analyte tested. While quality control is not mandated by specific laws, accrediting bodies often require it to maintain accreditation. Creating a paper trail and legal requirements are not the primary objectives of quality control, making choices A and C incorrect. Therefore, the correct answer is to improve the accuracy and reliability of reported test results.

4. 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.

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.
