Nursing Elites

1. A 20-year-old male shoots his hand with a nail gun while replacing roofing shingles. Which of the following cell types would be the first to aid in killing bacteria to prevent infection in his hand?

• A. Eosinophils
• B. Neutrophils
• C. Leukotrienes
• D. Monocytes

Correct answer: B

Rationale: Neutrophils are the first responders to bacterial infections. When there is a breach in the skin like in this scenario, neutrophils are quickly recruited to the site of injury to phagocytize and kill bacteria. Eosinophils are primarily involved in parasitic infections and allergic reactions, making choice A incorrect. Leukotrienes are lipid mediators involved in inflammation but are not cells, so choice C is incorrect. Monocytes are precursors to macrophages and play a role in immune response, but they are not the first cells to arrive at the site of a bacterial infection, making choice D incorrect.

2. A patient is hospitalized with active tuberculosis. The patient is receiving antitubercular drug therapy and is not responding to the medications. What do you suspect the patient is suffering from?

• A. Human immunodeficiency virus
• B. Drug-resistant tuberculosis
• C. Methicillin-resistant Staphylococcus aureus
• D. Vancomycin-resistant Staphylococcus aureus

Correct answer: B

Rationale: When a patient with active tuberculosis is not responding to antitubercular drug therapy, drug-resistant tuberculosis should be suspected. Drug-resistant tuberculosis occurs when the bacteria causing tuberculosis become resistant to the medications being used. Choices A, C, and D are incorrect because the scenario described does not align with HIV infection, methicillin-resistant Staphylococcus aureus, or vancomycin-resistant Staphylococcus aureus.

3. In nephritic syndrome compared to nephrotic syndrome, there is:

• A. higher amounts of albuminuria.
• B. negligible hematuria or absence of hematuria.
• C. presence of red blood cell casts in the urine.
• D. hypoalbuminemia

Correct answer: C

Rationale: In nephritic syndrome, the presence of red blood cell casts in the urine is a characteristic finding, reflecting glomerular inflammation and damage. This differentiates it from nephrotic syndrome, where red blood cell casts are typically absent. Choice A is incorrect because nephritic syndrome usually presents with less albuminuria compared to nephrotic syndrome. Choice B is incorrect as hematuria is a common feature of nephritic syndrome. Choice D is incorrect as hypoalbuminemia is more commonly associated with nephrotic syndrome.

4. An immunology nurse is caring for a patient. While planning care, which principle will the nurse remember? The primary role of IgA1 is to prevent infections in the:

• A. Blood
• B. Kidneys
• C. Lungs
• D. Mucous membranes

Correct answer: A

Rationale: The correct answer is A: Blood. IgA1 is mainly found in the blood and plays a crucial role in preventing infections by neutralizing pathogens. While IgA1 can be present in other body areas, its primary function is associated with preventing infections in the blood. Choices B, C, and D are incorrect as IgA1 is not primarily associated with the kidneys, lungs, or mucous membranes.

5. When discussing the risks associated with hormone replacement therapy (HRT) with a patient who has a history of coronary artery disease, what should the nurse emphasize?

• A. HRT may increase the risk of cardiovascular events such as heart attack and stroke.
• B. HRT may increase the risk of osteoporosis.
• C. HRT may decrease the risk of venous thromboembolism.
• D. HRT may increase the risk of breast cancer.

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, such as heart attack and stroke, especially in patients with a history of coronary artery disease. Choice B is incorrect because HRT is actually known to decrease the risk of osteoporosis. Choice C is incorrect as HRT is associated with an increased risk of venous thromboembolism. Choice D is also incorrect as HRT may slightly increase the risk of breast cancer.
