Nursing Elites

1. An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that normal changes associated with aging include:

• A. Improved blood flow
• B. Slowed metabolic rate
• C. Increased brain weight
• D. Improved nerve fiber conduction

Correct answer: B

Rationale: Normal changes associated with aging include a slowed metabolic rate and decreased brain weight. Option A, 'Improved blood flow,' is incorrect as aging is generally associated with reduced vascular health rather than improved blood flow. Option D, 'Improved nerve fiber conduction,' is incorrect as aging typically leads to a decline in nerve function rather than improvement.

2. The early stages of atheroma development are characterized by:

• A. macrophages full of oxidized low-density lipoprotein (LDL; i.e., foam cells) in the intima
• B. accumulation of lipids in the intima (i.e., fatty streak)
• C. accumulation of proteins such as collagen and elastin (i.e., fibrous cap)
• D. development of calcium and a necrotic lipid core

Correct answer: A

Rationale: The correct answer is A. In the early stages of atheroma development, macrophages accumulate oxidized low-density lipoprotein (LDL) and transform into foam cells, leading to the formation of fatty streaks in the intima of blood vessels. This process is a hallmark of the initial stages of atherosclerosis. Choice B is incorrect as it describes the accumulation of lipids in the intima, which is a later event following foam cell formation. Choice C is also incorrect as it refers to the accumulation of proteins forming the fibrous cap, which occurs at a later stage to stabilize the atheroma. Choice D is incorrect as it describes the development of calcium and a necrotic lipid core, typically seen in advanced atherosclerosis rather than the early stages.

3. A public health nurse is responsible for the administration of numerous immunizations. Which of the following guidelines regarding anaphylaxis should the nurse adhere to?

• A. The patient should be observed for anaphylaxis for 1 minute after administration.
• B. The patient should be observed for anaphylaxis for 5 minutes after administration.
• C. The patient should be observed for anaphylaxis for 30 minutes after administration.
• D. The patient should be observed for anaphylaxis for 90 minutes after administration.

Correct answer: C

Rationale: The correct answer is C: 'The patient should be observed for anaphylaxis for 30 minutes after administration.' This is because anaphylaxis can occur within minutes of administration of an immunization. By observing the patient for 30 minutes, the nurse can promptly identify and manage any signs of anaphylaxis. Choices A, B, and D are incorrect as they suggest shorter or longer observation periods, which may not be sufficient to detect and respond to anaphylaxis in a timely manner.

4. A hemoglobin electrophoresis is done to evaluate for sickle cell disease. The report reveals the person has HbAS, which means the person:

• A. is normal with no sickle cell disease.
• B. is a sickle cell carrier.
• C. has sickle cell anemia.
• D. has thalassemia.

Correct answer: B

Rationale: HbAS indicates sickle cell trait, not full-blown sickle cell anemia. Choice A is incorrect because HbAS indicates the presence of the sickle cell trait. Choice C is incorrect as sickle cell anemia is characterized by HbSS, not HbAS. Choice D is incorrect as thalassemia is a different type of hemoglobin disorder not indicated by HbAS.

5. Which of the following is a common cause of mechanical small intestine obstruction?

• A. Infection
• B. Postoperative adhesions
• C. Tumors
• D. Foreign body

Correct answer: B

Rationale: Postoperative adhesions are a common cause of mechanical small intestine obstruction. Adhesions can form after abdominal surgery, causing bands of scar tissue that may twist or pull the intestines, leading to obstruction. This is a more common cause compared to infection, tumors, or foreign bodies. Infection may lead to inflammation but is not a typical cause of mechanical obstruction. Tumors and foreign bodies can cause blockages but are less common than postoperative adhesions.
