Nursing Elites

1. 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.

2. A patient is diagnosed with ischemic heart disease. She is prescribed filgrastim (Neupogen). What effect will this medication provide in the treatment of ischemic heart disease?

• A. Increase platelets
• B. Decrease platelets
• C. Promote angiogenesis
• D. Prevent thrombus formation

Correct answer: C

Rationale: Filgrastim (Neupogen) is a medication that promotes the growth of white blood cells. In the context of ischemic heart disease, promoting angiogenesis, the formation of new blood vessels, can improve blood flow to the heart muscle, reducing ischemia and potentially improving cardiac function. Therefore, the correct answer is C. Choices A and B are incorrect because filgrastim does not directly affect platelet levels. Choice D is also incorrect as filgrastim does not prevent thrombus formation.

3. When communicating with a client who has cognitive impairment, which of the following will Nurse Dory use?

• A. Complete explanations with multiple details
• B. Pictures or gestures instead of words
• C. Stimulating words and phrases to capture the client’s attention
• D. Short words and simple sentences

Correct answer: D

Rationale: Nurse Dory will use short words and simple sentences when communicating with a client who has cognitive impairment. This approach is effective because it helps improve understanding and comprehension for individuals with cognitive challenges. Choice A is incorrect because complete explanations with multiple details may overwhelm or confuse clients with cognitive impairment. Choice B is not the most effective option as using pictures or gestures instead of words may not always be practical or necessary. Choice C is also not ideal as stimulating words and phrases may cause distraction rather than enhance communication for clients with cognitive impairment.

4. Which of the following stores electrolytes and acts as an electrolyte pool?

• A. Brain - Kidneys
• B. Bone - Nails
• C. Bone - Liver
• D. Liver - Pancreas

Correct answer: B

Rationale: Bones store electrolytes and act as a reservoir, maintaining a balance of essential minerals like calcium and phosphate. The correct pair in this context is 'Bone - Nails.' Choices A, C, and D are incorrect because the brain, kidneys, liver, and pancreas perform other functions in the body and are not primarily responsible for storing electrolytes.

5. Ivermectin (Stromectol) appears on a list of a patient's recent medications. The nurse who is reviewing the medications is justified in suspecting that the patient may have been receiving treatment for a parasitic infection with

• A. Entamoeba histolytica.
• B. Giardia lamblia.
• C. Strongyloides stercoralis.
• D. Plasmodium falciparum.

Correct answer: C

Rationale: Ivermectin (Stromectol) is commonly used to treat parasitic infections, particularly Strongyloides stercoralis. This parasitic infection is known to respond well to Ivermectin therapy. Entamoeba histolytica causes amoebiasis and is typically treated with antiprotozoal drugs like metronidazole, not Ivermectin. Giardia lamblia is a protozoan parasite causing giardiasis, which is usually treated with medications like metronidazole or tinidazole, not Ivermectin. Plasmodium falciparum is a malaria-causing parasite and is not treated with Ivermectin but with antimalarial medications like chloroquine or artemisinin-based combination therapies.
