Nursing Elites

1. Cushing syndrome is characterized by which disorder?

• A. Hypocortisolism
• B. Exophthalmos
• C. Hypercortisolism
• D. Hyperpigmentation

Correct answer: C

Rationale: Cushing syndrome is characterized by hypercortisolism, which is an excessive amount of cortisol in the body. Choice A, 'Hypocortisolism,' is incorrect as Cushing syndrome is associated with elevated cortisol levels. Choice B, 'Exophthalmos,' refers to bulging eyes and is not a characteristic feature of Cushing syndrome. Hyperpigmentation, as mentioned in choice D, can be present in Cushing syndrome due to increased ACTH levels stimulating melanocytes, but it is not the defining characteristic of the syndrome.

2. 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.

3. A patient is starting on alendronate (Fosamax) for osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

• A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
• B. Take the medication at bedtime to ensure absorption during sleep.
• C. Take the medication with milk to enhance calcium absorption.
• D. Take the medication with food to prevent gastrointestinal upset.

Correct answer: A

Rationale: The correct answer is to take alendronate with a full glass of water and remain upright for at least 30 minutes. This is essential to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because taking alendronate at bedtime can increase the risk of esophageal irritation due to lying down. Choice C is incorrect as taking alendronate with milk can reduce its absorption. Choice D is incorrect because alendronate should be taken on an empty stomach to enhance its effectiveness.

4. An influenza outbreak has spread through a long-term care residence, affecting many of the residents with severe malaise, fever, and nausea and vomiting. In an effort to curb the outbreak, the nurse has liaised with a physician to see if residents may be candidates for treatment with what drug?

• A. Saquinavir mesylate
• B. Oseltamivir phosphate
• C. Lamivudine
• D. Ribavirin

Correct answer: B

Rationale: The correct answer is B: Oseltamivir phosphate. Oseltamivir is an antiviral medication used to treat influenza infections. It works by inhibiting the neuraminidase enzyme of the influenza virus, reducing the spread of the virus in the body. Saquinavir mesylate (choice A) is used in the treatment of HIV, not influenza. Lamivudine (choice C) is also an antiviral medication primarily used in the treatment of HIV and hepatitis B, not influenza. Ribavirin (choice D) is used to treat certain viral infections like hepatitis C, respiratory syncytial virus (RSV), and some viral hemorrhagic fevers, but it is not a first-line treatment for influenza.

5. The canola plant's genome is altered to produce an herbicide-resistant crop. The canola oil produced from this crop is an example of a:

• A. pesticide-free food.
• B. saturated fat food.
• C. genetically modified food.
• D. product that is pure.

Correct answer: C

Rationale: The correct answer is C: genetically modified food. Canola plants with altered genomes to be herbicide-resistant are an example of genetically modified organisms (GMOs). Genetically modified foods have their genetic material modified for various purposes, such as enhancing resistance to pests, herbicides, or improving nutritional content. Choice A, 'pesticide-free food,' is incorrect because genetic modification does not necessarily make the food pesticide-free. Choice B, 'saturated fat food,' is incorrect as it does not relate to the genetic modification of the canola plant. Choice D, 'product that is pure,' is too vague and does not specifically address the genetic modification aspect of the canola plant.
