1. What is a cause of the crystallization within the synovial fluid of the joint affected by gouty arthritis?

• A. Destruction of proteoglycans
• B. Underexcretion of uric acid
• C. Overexcretion of uric acid
• D. Increased absorption of uric acid

Correct answer: B

Rationale: The correct answer is B: Underexcretion of uric acid. Gouty arthritis is primarily caused by the underexcretion of uric acid, leading to its accumulation in joints and subsequent crystallization. Choices A, C, and D are incorrect as they do not directly relate to the pathophysiology of gout. Destruction of proteoglycans, overexcretion of uric acid, and increased absorption of uric acid are not primary causes of gouty arthritis.

2. Which of the following would the nurse see in a client with thrombocytopenia?

• A. A decreased platelet cell count
• B. Decreased white blood cell count
• C. Increased red blood cell count
• D. An increased platelet cell count

Correct answer: A

Rationale: Thrombocytopenia is characterized by a decreased platelet cell count, leading to an increased risk of bleeding. Therefore, the correct answer is A. Choice B, a decreased white blood cell count, is not typically associated with thrombocytopenia. Choice C, an increased red blood cell count, is not a characteristic finding in thrombocytopenia. Choice D, an increased platelet cell count, is the opposite of what is observed in thrombocytopenia.

3. A nursing student having trouble moving her head from side to side is likely experiencing a problem with which type of neurons?

• A. General visceral efferent neurons
• B. Preganglionic neurons
• C. Parasympathetic postganglionic neurons
• D. Pharyngeal efferent neurons

Correct answer: D

Rationale: The correct answer is D: Pharyngeal efferent neurons. Pharyngeal efferent neurons are responsible for controlling head movements, including side-to-side motions. General visceral efferent neurons (Choice A) are involved in innervating smooth muscles and glands in the body's internal organs. Preganglionic neurons (Choice B) are part of the autonomic nervous system and connect the central nervous system to the ganglia. Parasympathetic postganglionic neurons (Choice C) are the second neurons in the parasympathetic nervous system pathway, responsible for innervating target organs. In this case, the issue with moving the head from side to side indicates a problem with the pharyngeal efferent neurons.

4. A male patient receiving androgen therapy is concerned about prostate cancer. What should the nurse explain about the risks associated with this therapy?

• A. Finasteride has been shown to reduce the risk of developing prostate cancer.
• B. Finasteride has no impact on the risk of developing prostate cancer.
• C. Finasteride may increase the risk of developing prostate cancer.
• D. Finasteride has no effect on the risk of prostate cancer.

Correct answer: A

Rationale: The correct answer is A. Finasteride, a type of androgen therapy, has been shown to reduce the risk of developing prostate cancer. It works by shrinking the prostate gland, which can help lower the risk of developing prostate cancer. However, while it may reduce the risk, regular screening is still recommended to monitor for any potential issues. Choice B is incorrect because finasteride does have an impact on reducing the risk of prostate cancer. Choice C is incorrect as finasteride is not known to increase the risk of developing prostate cancer. Choice D is incorrect as finasteride does have an effect on reducing the risk of prostate cancer.

5. 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.
