Nursing Elites

1. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture.
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

2. Which of the following lab values is elevated first after a client has a myocardial infarction?

• A. LDH
• B. troponin
• C. CPK
• D. SGOT

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

3. Which of the following tasks are appropriate for an LPN to perform?

• A. Adjusting the cervical traction device of a 68-year-old client as instructed by the charge nurse.
• B. performing operation on a woman in labour
• C. Assessing a 36-year-old man newly admitted for chest pain.
• D. Obtaining an occult blood sample from a 16-year-old client with ulcerative colitis.

Correct answer: D

Rationale: Tasks appropriate for an LPN to perform include teaching, obtaining samples, and documenting. LPNs can educate clients on care practices, such as teaching a new mother how to care for her baby. Obtaining samples, like an occult blood sample, falls within the scope of an LPN's responsibilities. Assessments, especially initial assessments, should be conducted by a registered nurse or physician, making option C incorrect. Adjusting devices like a cervical traction device should be done based on direct orders from prescribing providers, not charge nurses, making option A inappropriate for an LPN's role.

4. In a community hospital, a nurse is employed as a staff nurse and is supervised by a nurse manager. The nurse understands that in this position, the term authority most appropriately refers to which description?

• A. Accepting responsibility for the actions of others
• B. The official power to ensure that an organizational decision is enforced
• C. Bearing the legal responsibility for others' performance of tasks
• D. Taking responsibility for what staff members do

Correct answer: B

Rationale: The term authority refers to the official power of an individual to approve or command an action or to ensure that a decision is enforced. In the context of the nurse's position supervised by a nurse manager, having authority means having the official power to ensure that organizational decisions are carried out. Choice A, accepting responsibility for the actions of others, is more related to accountability rather than authority. Choice C, bearing the legal responsibility for others' performance of tasks, is more about legal liability rather than authority. Choice D, taking responsibility for what staff members do, is similar to choice A and is more about accountability rather than having the official power to enforce decisions. Therefore, the correct answer is B as it directly relates to the concept of authority in the context described.

5. The client has a new prosthetic hip, and the nurse is repositioning them. Which position should be avoided to prevent injury to the new prosthetic hip?

• A. abduction of the hip
• B. adduction of the hip
• C. flexing the hip at 80� flexion
• D. flexing the hip at 90�

Correct answer: B

Rationale: The correct answer is 'adduction of the hip.' When a client has a new prosthetic hip, adduction (movement of the leg toward the midline of the body) should be avoided to prevent injury to the new prosthetic hip. Abduction (movement of the leg away from the midline) is typically allowed and may even be encouraged. Flexing the hip at certain degrees is acceptable, but adduction should be avoided to prevent complications or dislocation of the prosthetic hip. Therefore, options A, C, and D are incorrect because they do not pose a direct risk to the new prosthetic hip compared to adduction.
