Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. What are the key interventions for managing a patient with asthma?

• A. Administer bronchodilators and monitor oxygen levels
• B. Encourage deep breathing exercises
• C. Provide corticosteroids and monitor for respiratory distress
• D. Provide antihistamines and monitor blood pressure

Correct answer: A

Rationale: The correct answer is A: Administer bronchodilators and monitor oxygen levels. Asthma management involves using bronchodilators to help open the airways and improve breathing. Monitoring oxygen levels is essential to ensure the patient is getting enough oxygen. Choice B, encouraging deep breathing exercises, can be helpful for some respiratory conditions but is not a key intervention for managing an acute asthma attack. Choice C, providing corticosteroids and monitoring for respiratory distress, is important for long-term asthma management and severe exacerbations but is not the immediate key intervention during an acute attack. Choice D, providing antihistamines and monitoring blood pressure, is not typically indicated for asthma management as asthma is primarily an airway disease, not a histamine-mediated condition.

3. What are early indicators of dehydration?

• A. Dry mouth
• B. Increased thirst
• C. Decreased urine output
• D. Dizziness

Correct answer: A

Rationale: The correct answer is A, dry mouth, and B, increased thirst are early indicators of dehydration. Dry mouth occurs when the body is dehydrated, and increased thirst is the body's way of trying to increase fluid intake to combat dehydration. Choices C and D, decreased urine output and dizziness, can be signs of severe dehydration but are not typically considered early indicators.

4. A nurse is caring for a client who has dementia. Which of the following interventions should the nurse take to minimize the risk of injury for this client?

• A. Use a bed exit alarm system
• B. Raise all four side rails while the client is in bed
• C. Apply one soft wrist restraint
• D. Dim the lights in the client's room

Correct answer: A

Rationale: Using a bed exit alarm system is crucial in minimizing the risk of injury for a client with dementia. This intervention helps alert staff when the client is attempting to leave the bed, reducing the chances of falls. Raising all four side rails while the client is in bed (Choice B) can lead to restraint-related issues and is not recommended unless necessary for safety reasons. Applying a soft wrist restraint (Choice C) is generally not the first choice in managing clients with dementia due to the risk of complications and loss of mobility. Dimming the lights in the client's room (Choice D) may not directly address the risk of injury associated with dementia and may even increase the risk of falls due to poor visibility.

5. A nurse at a long-term care facility is transcribing new prescriptions for four clients. Which of the following prescriptions is accurately transcribed by the nurse?

• A. KCl 10 mEq PO once daily
• B. KCl 20 mEq PO once daily
• C. Potassium gluconate PO
• D. Potassium chloride 20 mEq PO every morning

Correct answer: D

Rationale: The correct answer is D because it accurately transcribes the prescription by specifying the medication (Potassium chloride), the dose (20 mEq), the route (PO for by mouth), and the frequency (every morning). Choice A is incorrect as it specifies a lower dose compared to the correct prescription. Choice B is incorrect due to an inaccurate dose. Choice C is incorrect as it lacks specificity regarding the type of potassium prescribed and the dose.
