Age greater than 65 years
Genetic factors
History of multiple births
Correct Answer : A,B,C
A. Early menarche increases lifetime exposure to estrogen, raising breast cancer risk.

Correct Answer is D
Explanation
A. Although monitoring hemodynamic parameters is important, this option does not address the immediate issue of low preload, as indicated by the low CVP and PAWP, suggesting hypovolemia.
B. Furosemide is a diuretic and would further decrease intravascular volume, which is inappropriate given the signs of hypovolemia.
C. Decreasing IV fluids would exacerbate the low preload and worsen the client's condition by reducing intravascular volume even further.
D. Administering 0.9% Normal Saline @ 150 mL/hr is the most appropriate intervention. The low CVP and PAWP indicate hypovolemia, and increasing fluid administration will help to increase the preload, thereby improving the client's hemodynamic status.
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.
