Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy.

Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Tetralogy of Fallot is a congenital heart defect that includes four specific heart abnormalities: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy.
Choice B rationale
This choice incorrectly identifies aortic stenosis and atrial septal defect as components of Tetralogy of Fallot. In fact, the condition involves pulmonic stenosis and a ventricular septal defect.
Choice C rationale
This choice incorrectly identifies pulmonary stenosis and aortic hypertrophy as components of Tetralogy of Fallot. In fact, the condition involves pulmonic stenosis and right ventricular hypertrophy.
Choice D rationale
This choice incorrectly identifies aortic stenosis as a component of Tetralogy of Fallot. In fact, the condition involves pulmonic stenosis.

Correct Answer is ["A","B","C","D"]

Explanation

Choice A rationale
Flushing and sweating can be an indication of magnesium sulfate toxicity. Magnesium sulfate is a medication used to prevent seizures in women with severe preeclampsia. However, if the levels of magnesium become too high, it can lead to toxicity15.
Choice B rationale
A decreased level of consciousness can be an indication of magnesium sulfate toxicity. High levels of magnesium can affect the central nervous system, leading to drowsiness, lethargy, and decreased responsiveness15.
Choice C rationale
Urinary output less than 30 mL/hr can be an indication of magnesium sulfate toxicity. Magnesium sulfate can affect kidney function, leading to decreased urine output15.
Choice D rationale
Respirations fewer than 12/min can be an indication of magnesium sulfate toxicity. High levels of magnesium can depress the respiratory system, leading to slow or shallow breathing15.

A. Intravenous fluids (IVF) at maintenance rate B. Meperidine IV for pain C. Ice packs to the affected area for 15 min on/15 min off D. Oxygen 2 L/min via nasal cannula

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"C"},"C":{"answers":"B"},"D":{"answers":"A"}}

Explanation

Choice A rationale
Intravenous fluids (IVF) at maintenance rate is anticipated for the client. Dehydration can increase the viscosity of the blood and promote sickling in clients with sickle cell disease. Therefore, maintaining hydration is crucial in managing sickle cell crises.
Choice B rationale
Meperidine IV for pain is contraindicated for the client. Meperidine has been associated with a higher risk of seizures, especially in clients with kidney dysfunction, which can occur in sickle cell disease due to sickling in the renal vasculature.
Choice C rationale
Ice packs to the affected area for 15 min on/15 min off is nonessential for the client. While cold therapy can help reduce inflammation and numb pain, it can also lead to vasoconstriction, which can potentially exacerbate sickling. Therefore, it’s generally recommended to use warm compresses rather than ice packs in clients with sickle cell disease.
Choice D rationale
Oxygen 2 L/min via nasal cannula is anticipated for the client. Hypoxia can trigger sickling in clients with sickle cell disease, so oxygen therapy is often used to increase oxygen saturation and reduce the risk of sickling.
