Hyperkalemia occurs when the body contains an excessive amount of potassium. In severe circumstances, hyperkalemia can lead to abnormal heart rhythms. Lowering potassium levels is essential to treating those who suffer from hyperkalemia. However, patients with severe hyperkalemia are initially given an injection of calcium, even though calcium does not lower the body’s potassium levels. Instead, the calcium protects the heart from the negative effects of excess potassium. Patients are then given doses of a medicine, such as insulin or albuterol, that help reduce potassium levels.
The information given, if true, most strongly supports which of the following?
(A) If an injection of calcium is not given first, medicines such as insulin or albuterol could exacerbate the conditions of severe hyperkalemia.
(B) Patients with mild to moderate hyperkalemia are not given calcium to protect their heart.
(C) Patients given calcium injections cannot be given insulin until the calcium has provided its full effect.
(D) Not all treatments for hyperkalemia are intended to address the root cause of the condition.
(E) Patients cannot reduce their potassium levels without a sufficient intake of calcium.

Hey, So I will give it a try -
We know -
- Hyperkalemia is a result of excess potassium
- It can lead to abnormal heart rhythms; it's essential to lower the potassium levels.
- However, doctors give Calcium injection to start with, even though it doesn't help with Potassium levels
- It's meant to protect the heart
- Insulin injections help reduce the potassium levels
Let's look at D first
Quote:
This is a reasonable inference, since we know that Calcium injections don't reduce the Potassium levels, given that IT IS the root cause of hyperkalemia.
So - essentially hyperkalemia would not be treated just with Calcium injections.
Lets look at A
Quote:
So, we know Calcium is meant to protect the Heart from the negative effects of excess potassium, but we can't surely infer that insulin/albuterol can excerabate the hyperkalemia condition. What if there is an alternate side effect of Potassium + Insulin?
In the absence of D, A could definitely be inferred. But in the presence of D, A goes slightly beyond the scope.
Hope that helps.
