Nursing Elites

1. What clinical manifestations would the nurse expect to find in a client who is experiencing anaphylaxis?

• A. Dilated bronchioles, constriction of peripheral blood vessels, decreased capillary permeability
• B. Asthma, deep vein thrombosis, hepatic encephalopathy
• C. Narrowing of the bronchioles, dilation of the peripheral blood vessels, increased capillary permeability
• D. Left-sided heart failure, pulmonary embolism, urinary tract infection

Correct answer: C

Rationale: In anaphylaxis, the client would present with narrowing of the bronchioles, dilation of the peripheral blood vessels, and increased capillary permeability. These manifestations lead to symptoms such as difficulty breathing, low blood pressure, and swelling. Choices A, B, and D are incorrect because they do not describe the typical clinical manifestations of anaphylaxis.

2. In Guillain-Barre syndrome, what pathophysiologic process underlies the deficits that accompany the degeneration of myelin in the peripheral nervous system (PNS)?

• A. The destruction of myelin results in a reduction in Schwann cell production in the client's PNS.
• B. The lack of myelin surrounding nerve cells compromises the axonal transport system.
• C. Without remyelination, the axon will eventually die.
• D. A deficit of myelin makes the client more susceptible to infection by potential pathogens.

Correct answer: C

Rationale: In Guillain-Barre syndrome, the destruction of myelin leads to axonal damage. If remyelination does not occur, the axon will eventually degenerate and die, impacting nerve function. Choice A is incorrect because the destruction of myelin does not affect Schwann cell production. Choice B is incorrect as the lack of myelin directly affects the conduction of nerve impulses, not the axonal transport system. Choice D is incorrect as a deficit of myelin does not predispose the client to infections by potential pathogens.

3. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). What is a critical point the nurse should include in the patient education?

• A. Tamoxifen may increase the risk of venous thromboembolism.
• B. Tamoxifen may decrease the risk of osteoporosis.
• C. Tamoxifen may cause hot flashes and other menopausal symptoms.
• D. Tamoxifen may cause weight gain and fluid retention.

Correct answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots. Choice B is incorrect because tamoxifen does not decrease the risk of osteoporosis. Choice C is incorrect as tamoxifen may cause hot flashes and other menopausal symptoms but this is not the critical point for patient education. Choice D is incorrect as tamoxifen may cause weight gain and fluid retention, but it is not the critical point that the nurse should focus on in patient education.

4. When assessing a 7-year-old child's pain after an emergency appendectomy, what is the most appropriate tool for the nurse to use?

• A. Use a visual analog scale (VAS) to assess the pain.
• B. Ask the child to rate their pain on a scale of 0 to 10.
• C. Use the Wong-Baker FACES scale to assess the pain.
• D. Ask the parents to describe the child's pain behavior.

Correct answer: C

Rationale: The correct answer is to use the Wong-Baker FACES scale to assess the child's pain. This scale is specifically designed for children and uses facial expressions of varying intensities to help them communicate their pain levels effectively. Choices A and B may not be as suitable for a young child who may have difficulty understanding or using a numerical scale. Choice D involving parents may not provide an accurate reflection of the child's pain experience, as it is essential to assess the child's self-reporting.

5. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strange and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:

• A. Alzheimer's disease.
• B. Vascular dementia.
• C. Dementia with Lewy bodies.
• D. Frontotemporal dementia.

Correct answer: C

Rationale: The symptoms described in the scenario, such as visual hallucinations, fluctuations in cognition, and parkinsonism (bradykinesia and limb rigidity), are classic features of dementia with Lewy bodies (DLB). DLB is characterized by the presence of Lewy bodies in the brain, which are abnormal protein deposits. Alzheimer's disease (Choice A) typically presents with memory loss as a predominant symptom, which is not a major concern in this case. Vascular dementia (Choice B) is associated with a history of cerebrovascular disease and is not supported by the symptoms described. Frontotemporal dementia (Choice D) usually presents with changes in behavior and personality, rather than the symptoms described in the scenario.
