Nursing Elites

1. What are the characteristics of the inflammatory process?

• A. Loss of function, coolness
• B. Pain, redness
• C. Heat, pallor
• D. Swelling, pallor

Correct answer: B

Rationale: The correct answer is B: Pain, redness. Inflammation is characterized by pain and redness as part of the body's response to tissue injury. Choice A, loss of function and coolness, are not primary characteristics of inflammation. Choice C, heat and pallor, may be present in some cases but are not as consistently associated with inflammation as pain and redness. Choice D, swelling and pallor, includes swelling which is common in inflammation but pallor is not a typical characteristic.

2. Thrombocytopenia is which disorder below?

• A. Increased blood coagulation
• B. Increased platelet production
• C. Increased number of infections
• D. Decreased platelet production

Correct answer: D

Rationale: Thrombocytopenia is a disorder characterized by a decreased platelet count or decreased platelet production, which affects blood clotting. Choice A, 'Increased blood coagulation,' is incorrect as thrombocytopenia is associated with decreased platelets, leading to impaired clotting. Choice B, 'Increased platelet production,' is incorrect as thrombocytopenia is characterized by a decrease in platelet production. Choice C, 'Increased number of infections,' is unrelated to thrombocytopenia, which primarily involves low platelet levels.

3. What are the signs of thyroid crisis resulting from Graves' disease?

• A. Constipation with gastric distension.
• B. Bradycardia and bradypnea.
• C. Hyperthermia and tachycardia.
• D. Constipation and lethargy.

Correct answer: C

Rationale: In a thyroid crisis resulting from Graves' disease, the patient typically experiences symptoms such as hyperthermia (elevated body temperature) and tachycardia (rapid heart rate). These symptoms are indicative of the hypermetabolic state seen in thyroid storm. Choices A and D are incorrect as constipation and lethargy are not typical signs of a thyroid crisis; instead, patients with hyperthyroidism often experience diarrhea and agitation. Choice B is incorrect because bradycardia (slow heart rate) and bradypnea (slow breathing rate) are more commonly associated with hypothyroidism rather than a thyroid crisis in Graves' disease.

4. Innate resistance or immunity:

• A. Involves 'memory'
• B. Is a development of an individual's later years
• C. Is a relatively slow and specific process
• D. Depends on physical, mechanical, and biochemical barriers

Correct answer: D

Rationale: Innate resistance or immunity relies on the body's natural defenses like physical, mechanical, and biochemical barriers. These barriers act as the first line of defense against pathogens and do not involve memory (choice A). Innate immunity is present from birth and does not develop over an individual's later years (choice B). Additionally, innate immunity is a rapid and nonspecific process, not a slow and specific one (choice C). Therefore, the correct answer is D.

5. A client with multiple sclerosis (MS) is frustrated by tremors associated with the disease. How should the nurse explain why these tremors occur? Due to the demyelination of neurons that occurs in MS:

• A. there is an imbalance in acetylcholine and dopamine, leading to tremors.
• B. there is a disruption in nerve impulse conduction, causing tremors.
• C. muscles are unable to receive impulses, resulting in tremors.
• D. the reflex arc is disrupted, leading to muscle tremors.

Correct answer: B

Rationale: In multiple sclerosis (MS), demyelination of neurons disrupts nerve impulse conduction. This disruption in nerve impulses can lead to tremors, explaining why the client experiences tremors in MS. Choice A is incorrect because tremors in MS are primarily due to nerve conduction issues, not an imbalance in acetylcholine and dopamine. Choice C is incorrect as it oversimplifies the process; the issue lies in nerve impulses, not the muscle's ability to receive them. Choice D is incorrect as the primary cause of tremors in MS is the disruption in nerve impulse conduction, not the reflex arc being disrupted.
