Nuclear medicine scan

Magnetic resonance imaging (MRI)

Esophagogastroduodenoscopy (EGD)

Abdominal arteriogram

Answer and Explanation

The Correct Answer is C

A. Nuclear medicine scan is less commonly used for diagnosing gastric pain and dyspepsia.

B. Magnetic resonance imaging (MRI) is not the first choice for gastrointestinal issues.

C. Esophagogastroduodenoscopy (EGD) allows direct visualization of the upper GI tract, making it the most accurate diagnostic tool.

D. Abdominal arteriogram is typically used for vascular issues, not for diagnosing dyspepsia or gastric pain.

Correct Answer is B

Explanation

A. Adenosine 6 mg IV push: Adenosine is used for certain supraventricular tachycardias, but immediate cardioversion is the first priority for a client with atrial flutter and chest pain.

B. Immediate cardioversion: This is the correct answer. Immediate cardioversion is indicated for atrial flutter with signs of hemodynamic instability, such as chest pain and shortness of breath.

C. Adenosine 12 mg IV push: Adenosine may be used after the first dose of 6 mg if the initial dose was ineffective, but cardioversion takes precedence for unstable patients.

D. Amiodarone 150 mg bolus followed by a 24-hour drip: Amiodarone is an antiarrhythmic used for rate control or rhythm conversion but is not the first step for hemodynamically unstable clients with atrial flutter.

A. Na + 134 B. K+ 6.1 C. K+ 2.1 D. Mg+ 18

Correct Answer is C

Explanation

A. Mild hyponatremia (Sodium < 135 mEq/L) typically does not produce distinctive ECG changes. This value is unlikely to correlate with the presence of U waves.

B. Hyperkalemia (Potassium > 5.0 mEq/L) is associated with peaked T waves, widened QRS complexes, and flattened or absent P waves, not U waves.

C. Hypokalemia (Potassium < 3.5 mEq/L) is the primary cause of U waves. A potassium level of 2.1 mEq/L is significantly low and can result in ECG changes, including U waves, ST segment depression, and prolonged QT intervals. These changes reflect altered ventricular repolarization.

D. Hypermagnesemia (Magnesium > 2.5 mEq/L) can cause ECG changes such as prolonged PR and QRS intervals, bradycardia, and heart block. However, such an extreme magnesium level of 18 mEq/L would cause severe toxicity and is not associated with U waves.
