Nursing Elites

1. When a patient asks the nurse what hypersensitivity is, how should the nurse respond? Hypersensitivity is best defined as:

• A. A reduced immune response found in most pathologic states
• B. A normal immune response to an infectious agent
• C. An excessive or inappropriate response of the immune system to a sensitizing antigen
• D. Antigenic desensitization

Correct answer: C

Rationale: Hypersensitivity is correctly defined as an excessive or inappropriate response of the immune system to a sensitizing antigen. This response leads to tissue damage or other clinical manifestations. Choice A is incorrect as hypersensitivity involves an exaggerated, not a reduced, immune response. Choice B is incorrect because hypersensitivity is not a normal immune response to an infectious agent but rather an exaggerated one. Choice D is incorrect as it refers to desensitization, which is the opposite of hypersensitivity.

2. In nephritic syndrome compared to nephrotic syndrome, there is:

• A. higher amounts of albuminuria.
• B. negligible hematuria or absence of hematuria.
• C. presence of red blood cell casts in the urine.
• D. hypoalbuminemia

Correct answer: C

Rationale: In nephritic syndrome, the presence of red blood cell casts in the urine is a characteristic finding, reflecting glomerular inflammation and damage. This differentiates it from nephrotic syndrome, where red blood cell casts are typically absent. Choice A is incorrect because nephritic syndrome usually presents with less albuminuria compared to nephrotic syndrome. Choice B is incorrect as hematuria is a common feature of nephritic syndrome. Choice D is incorrect as hypoalbuminemia is more commonly associated with nephrotic syndrome.

3. A 75-year-old male presents with chest pain on exertion. The chest pain is most likely due to hypoxic injury secondary to:

• A. Malnutrition
• B. Free radicals
• C. Ischemia
• D. Chemical toxicity

Correct answer: C

Rationale: The correct answer is C: Ischemia. In this scenario, the 75-year-old male experiences chest pain on exertion, which is indicative of angina. Angina is primarily caused by reduced blood flow to the heart muscle, leading to hypoxic injury. This condition is known as ischemia. Options A, B, and D are incorrect. Malnutrition does not typically cause chest pain related to exertion. Free radicals and chemical toxicity are not common causes of chest pain in the context described. Therefore, the most likely cause of chest pain in this case is ischemia due to reduced blood flow.

4. A patient is prescribed acyclovir (Zovirax) for the treatment of genital herpes. What is the expected outcome of this medication?

• A. Decreased testosterone production
• B. Decreased libido
• C. Decreased viral shedding
• D. Decreased bacterial replication

Correct answer: C

Rationale: The expected outcome of acyclovir (Zovirax) for the treatment of genital herpes is decreased viral shedding. Acyclovir is an antiviral medication that works by inhibiting the replication of the herpes virus, thereby reducing viral shedding and helping to control outbreaks. Choice A, decreased testosterone production, and Choice B, decreased libido, are unrelated outcomes of acyclovir treatment for genital herpes. Choice D, decreased bacterial replication, is also incorrect as acyclovir specifically targets viruses and does not affect bacterial replication.

5. When does pain in the lower extremities due to peripheral artery disease usually worsen?

• A. with rest because blood flow decreases.
• B. with elevation of the extremity because blood is diverted away.
• C. when the leg is in a dependent position because blood pools.
• D. when the leg is touched or massaged because cytokines are released.

Correct answer: B

Rationale: Pain in the lower extremities due to peripheral artery disease usually worsens with elevation of the extremity because blood is diverted away from the affected area, leading to decreased perfusion and exacerbation of symptoms. Choices A, C, and D are incorrect because resting, dependent position, and touch/massage do not typically worsen the pain associated with peripheral artery disease.
