Nursing Elites

1. What are the early signs of compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized redness and swelling
• C. Fever and infection
• D. Loss of sensation in the affected area

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. These signs are typical early indicators of compartment syndrome, suggesting compromised circulation. Choice B, localized redness and swelling, can be seen in conditions like cellulitis but are not specific to compartment syndrome. Choice C, fever and infection, are not characteristic early signs of compartment syndrome. Choice D, loss of sensation in the affected area, is more indicative of nerve damage rather than being one of the early signs of compartment syndrome.

2. A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?

• A. It delivers a preset amount of inspiratory pressure throughout the breathing cycle
• B. It has a continuous adjustment feature that changes the airway pressure throughout the cycle
• C. It delivers a preset amount of airway pressure throughout the breathing cycle
• D. It delivers positive pressure at the end of each breath

Correct answer: C

Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

3. A nurse is caring for a client who has dehydration. The client has a peripheral IV and a prescription for an infusion of 0.9% sodium chloride 1,000 mL with 40 mEq potassium chloride to infuse over 1 hr. Which of the following actions should the nurse take first?

• A. Teach the client to report findings of IV extravasation
• B. Evaluate the patency of the IV
• C. Consult with the pharmacist about the prescription
• D. Verify the prescription with the provider

Correct answer: D

Rationale: The nurse's priority action should be to verify the prescription with the provider. This is crucial to prevent injury from fluid volume overload and rapid potassium infusion. Verifying the prescription ensures that the correct solution, rate, and additives are ordered according to the client's condition. While evaluating the patency of the IV is important, verifying the prescription takes precedence to ensure patient safety. Consulting with the pharmacist can be beneficial, but confirming the prescription with the provider is the immediate priority. Teaching the client about IV extravasation is important but is not the first action the nurse should take in this scenario.

4. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

5. A client scheduled for electromyography (EMG) will have small needle electrodes inserted into the muscles. What should the nurse include in the teaching?

• A. You will receive a fixed dose of radioisotope 2 hours before the procedure.
• B. Momentary flushing will occur at the beginning of the procedure.
• C. You should inform your provider if you are claustrophobic.
• D. You should expect insertion of small needle electrodes into the muscles.

Correct answer: D

Rationale: The correct answer is D. During an electromyography (EMG) procedure, small needle electrodes are inserted into the muscles to assess muscle weakness and nerve responses. Choices A, B, and C are incorrect because radioisotope is not used in EMG, flushing is not a typical occurrence, and claustrophobia is more relevant for imaging procedures like MRI or CT scans, not EMG.
