Nursing Elites

1. What ECG changes are seen with hyperkalemia?

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

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

2. What is the expected ECG finding in a patient with hypokalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Widened QRS complexes
• D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

3. A nurse is caring for a client who has increased intracranial pressure (ICP). Which of the following interventions should the nurse implement?

• A. Place several pillows behind the client's head
• B. Place the client in a Sim's position
• C. Keep the client's neck in a midline position
• D. Maintain flexion of the client's hips at a 90° angle

Correct answer: C

Rationale: Keeping the client's neck in a midline position is crucial for managing increased intracranial pressure. This position helps optimize blood flow and minimizes the risk of further increasing ICP. Placing several pillows behind the client's head (Choice A) may inadvertently elevate the head, potentially worsening ICP. Placing the client in a Sim's position (Choice B) or maintaining flexion of the client's hips at a 90° angle (Choice D) are not directly related to managing increased ICP.

4. What is the first action a healthcare provider should take for a patient with possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the initial priority action for a patient with possible acute coronary syndrome. Nitroglycerin helps dilate blood vessels, reduce chest pain, and improve blood flow to the heart muscle. This helps in relieving symptoms and preventing further damage to the heart. Establishing IV access, auscultating heart sounds, and obtaining cardiac enzymes are important steps in the assessment and management of acute coronary syndrome but are not the first actions to be taken. IV access may be needed for administering medications or fluids, auscultating heart sounds helps in assessing the heart's function, and obtaining cardiac enzymes aids in diagnosing a heart attack.

5. What should the nurse do when a patient experiences abdominal cramping during enema administration?

• A. Lower the height of the enema solution container
• B. Stop the procedure and remove the tubing
• C. Continue the enema at a slower rate
• D. Increase the flow of the enema solution

Correct answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the nurse should lower the height of the enema solution container. Lowering the height helps relieve cramping by slowing down the flow of the enema, reducing discomfort for the patient. Choice B, stopping the procedure and removing the tubing, is incorrect as it does not directly address the cramping issue. Choice C, continuing the enema at a slower rate, could potentially worsen the cramping by prolonging the discomfort. Choice D, increasing the flow of the enema solution, is also incorrect as it may intensify the cramping and cause more discomfort to the patient.
