Nursing Elites

1. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

2. Herbal therapy has several indications for use. Primarily, herbal therapy is:

• A. used to treat many common complaints and diseases.
• B. used to promote certain types of low-carb diets.
• C. used as an adjunct to medications.
• D. used to create a diet without salt and carbohydrates.

Correct answer: A

Rationale: The correct answer is A: 'used to treat many common complaints and diseases.' Herbal therapy is commonly used to address a variety of health issues and ailments by utilizing natural remedies derived from plants. Choices B, C, and D are incorrect because herbal therapy's primary purpose is not to promote specific diets, act as an adjunct to medications, or create specific dietary restrictions, but rather to provide alternative treatment options for various health conditions.

3. What is appropriate care for a client with neutropenia?

• A. Avoiding fresh fruits and vegetables.
• B. Having a private room.
• C. Wearing a mask when out of the room.
• D. Practicing routine hand washing.

Correct answer: C

Rationale: When a client has neutropenia, they have low white blood cell levels, which increases the risk of infections due to a weakened immune system. Wearing a mask when out of the room is crucial to reduce the risk of exposure to respiratory infections. Avoiding fresh fruits and vegetables is also necessary as they may contain harmful pathogens. Having a private room helps minimize exposure to pathogens and ensures that visitors are carefully screened for any signs of illness. Routine hand washing is essential to prevent the spread of infections in the healthcare setting, but the most direct measure to protect the client from potential infections is wearing a mask when out of the room.

4. When administering intravenous electrolyte solution, what precaution should the nurse take?

• A. Infuse hypertonic solutions cautiously.
• B. Mix no more than 60 mEq of potassium per liter of fluid.
• C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
• D. Monitor the client's digitalis dosage for adjustments due to IV calcium.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, preventing the infiltration of calcium is crucial to avoid tissue necrosis and sloughing, making choice C the correct answer. Choice A is revised to 'Infuse hypertonic solutions cautiously' because hypertonic solutions should be infused cautiously to prevent adverse effects. Choice B is corrected to 'Mix no more than 60 mEq of potassium per liter of fluid' as exceeding this limit can lead to hyperkalemia. Choice D is modified to 'Monitor the client's digitalis dosage for adjustments due to IV calcium' as it is essential to monitor the digitalis dosage for potential adjustments when IV calcium is administered; however, this choice is incorrect here as it inaccurately suggests adjusting the digitalis dosage due to IV calcium, which could lead to harmful effects.

5. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.
