Nursing Elites

1. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?

• A. Neurogenic shock
• B. Cardiogenic shock
• C. Hypovolemic shock
• D. Anaphylactic shock

Correct answer: D

Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.

2. What is the most effective method to prevent infection in the newborn?

• A. Using disposable items
• B. Practicing proper hand hygiene by staff and family
• C. Administering prophylactic antibiotics
• D. Isolating the newborn from others

Correct answer: B

Rationale: The most effective method to prevent infection in newborns is by practicing proper hand hygiene by staff and family. This is crucial as it helps reduce the transmission of infectious agents, protecting vulnerable newborns. Using disposable items may help, but proper hand hygiene is more effective. Administering prophylactic antibiotics without a specific indication can lead to antibiotic resistance and is not recommended. Isolating the newborn from others is not practical and may not be necessary if proper hand hygiene is maintained.

3. Which factor is most likely to cause a "brittle" diabetic state in a child with type 1 diabetes?

• A. Noncompliance with diet
• B. Insulin resistance
• C. Frequent infections
• D. Hypothyroidism

Correct answer: C

Rationale: Frequent infections can destabilize blood sugar levels, leading to a "brittle" diabetic state in children with type 1 diabetes. Infections increase metabolic demands and can result in significant blood glucose fluctuations, requiring careful monitoring and adjustment of insulin therapy. Noncompliance with diet may affect blood sugar control but is not the primary cause of a "brittle" state. Insulin resistance is more common in type 2 diabetes rather than type 1. Hypothyroidism can impact metabolism but is not directly linked to the development of a "brittle" diabetic state in type 1 diabetes.

4. Which laboratory value at the time of diagnosis should the nurse anticipate would determine the worst prognosis for a child with leukemia?

• A. Slow response to chemotherapy
• B. Platelets of 150,000/mcL
• C. Leukocytes less than 10,000/mcL
• D. Leukocytes of 275,000/mcL

Correct answer: D

Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.

5. What organism is a parasite that causes acute diarrhea?

• A. Shigella organisms
• B. Salmonella organisms
• C. Giardia lamblia
• D. Escherichia coli

Correct answer: C

Rationale: Giardia lamblia is a protozoan parasite known to cause acute diarrhea, often through contaminated water or food. Shigella, Salmonella, and E. coli are bacterial pathogens that also cause diarrhea but are not parasites.
