Nursing Elites

1. After studying about fungi, which information indicates a correct understanding of fungi? Fungi causing deep or systemic infections:

• A. Are easily treated with penicillin
• B. Are extremely rare
• C. Never occur with other infections
• D. Are commonly opportunistic

Correct answer: D

Rationale: The correct answer is D: 'Are commonly opportunistic.' Fungi causing deep or systemic infections are commonly opportunistic, particularly in individuals with compromised immune systems. Choice A is incorrect because fungi infections are not easily treated with penicillin. Choice B is incorrect as deep or systemic fungal infections are not extremely rare. Choice C is incorrect as fungal infections can co-occur with other infections.

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. What is a common cause of a pulmonary embolism?

• A. An autoimmune disorder
• B. A venous blood clot from the lower extremity
• C. An increase in intracranial pressure
• D. Hypotension

Correct answer: B

Rationale: A pulmonary embolism is commonly caused by a blood clot that originates in the venous system of the lower extremity and travels to the lungs, blocking blood flow. This clot is known as a venous thromboembolism. An autoimmune disorder (Choice A) is not typically associated with pulmonary embolism. Intracranial pressure (Choice C) refers to pressure inside the skull and is unrelated to pulmonary embolism. Hypotension (Choice D) is low blood pressure and is not a common cause of pulmonary embolism.

4. A nurse is caring for a client with a newly inserted pacemaker. What is the most important nursing action post-procedure?

• A. Monitor the insertion site for signs of infection.
• B. Educate the client about activity restrictions.
• C. Monitor the client's heart rate and rhythm.
• D. Assess the client's lung sounds for signs of fluid overload.

Correct answer: A

Rationale: Post-procedure, monitoring the insertion site for signs of infection is crucial because it helps in early detection of any potential complications such as infection. While educating the client about activity restrictions, monitoring the client's heart rate and rhythm, and assessing lung sounds for signs of fluid overload are important aspects of care, the immediate priority post-procedure is to prevent infection at the insertion site, which could lead to serious complications.

5. During an assessment of a male client suspected of having a disorder of motor function, which finding would suggest a possible upper motor neuron (UMN) lesion?

• A. Hypotonia
• B. Hyperreflexia
• C. Muscle atrophy
• D. Fasciculations

Correct answer: B

Rationale: Hyperreflexia, or exaggerated reflexes, is a common sign of an upper motor neuron (UMN) lesion. An UMN lesion indicates damage to the central nervous system pathways that control movement. Hypotonia (choice A) refers to reduced muscle tone, which is more indicative of lower motor neuron lesions. Muscle atrophy (choice C) suggests long-standing denervation or disuse of muscles. Fasciculations (choice D) are involuntary muscle contractions that can be seen in lower motor neuron lesions, like in amyotrophic lateral sclerosis (ALS), rather than UMN lesions.
