The nurse is caring for a client who has frequent gastric pain and dyspepsia. Which procedure would the nurse expect the health care provider to order to make an accurate diagnosis?
Nuclear medicine scan
Magnetic resonance imaging (MRI)
Esophagogastroduodenoscopy (EGD)
Abdominal arteriogram
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 C
Explanation
A. Using a feminine pad at night instead of a tampon can reduce the risk of TSS, which is correct.

D. Hand hygiene before inserting a tampon is critical for preventing TSS. This statement is correct.
Correct Answer is D
Explanation
A. Hypercalcemia (Calcium > 10.5 mg/dL) can lead to shortened QT intervals, not prolonged ones, and is unlikely to cause Torsades de Pointes.
B. A magnesium level of 3.1 mEq/L is slightly elevated and would not contribute to QT prolongation or Torsades de Pointes. In fact, magnesium supplementation is a treatment for this condition.
C. Hypokalemia (Potassium < 3.5 mEq/L) can prolong the QT interval and contribute to dysrhythmias, but it is less commonly a direct cause of Torsades de Pointes compared to hypomagnesemia. A potassium level of 2.6 mEq/L is low but would not typically result in Torsades without coexisting hypomagnesemia.
D. Hypomagnesemia (Magnesium < 1.5 mEq/L) disrupts the heart's electrical activity, prolonging the QT interval and increasing the risk of polymorphic ventricular tachycardia, like Torsades de Pointes. Magnesium is critical for stabilizing myocardial electrical conduction, and a value of 1.1 mEq/L indicates significant deficiency, consistent with this dysrhythmia.
