A nurse is evaluating a client who had a left-sided cardiac catheterization with an upper extremity insertion site.
Which of the following actions should the nurse take?

Choice A rationale

Administering packed RBCs is important but is not the highest priority. Stabilizing the client’s hemodynamic status is critical first.

Choice B rationale

Elevating the client's feet can help with blood circulation but does not address the immediate need to stabilize blood pressure and fluid volume.

Choice C rationale

Initiating a dopamine IV infusion can help with hypotension, but it is not the first action. Stabilizing the client with fluids is a higher priority.

Choice D rationale

Increasing the client's IV fluid rate is the highest priority to address hypotension and ensure adequate blood volume before administering blood products or other medications. .

Choice A rationale

Alcoholism is a common cause of hypomagnesemia due to poor dietary intake, increased renal excretion, and gastrointestinal losses. Chronic alcohol consumption leads to malnutrition and loss of magnesium through the urine, contributing to low magnesium levels.

Choice B rationale

Dehydration typically leads to hemoconcentration, which can elevate, rather than decrease, magnesium levels. Thus, it is not usually associated with low magnesium levels.

Choice C rationale

Kidney failure generally causes hypermagnesemia, not hypomagnesemia, because the kidneys cannot efficiently excrete magnesium, leading to its accumulation in the blood.

Choice D rationale

Excessive magnesium intake would result in hypermagnesemia, not hypomagnesemia, as the body accumulates more magnesium than it can excrete.
