Prioritization Question

[MiaGirl]

I need some sunshine or guidance. I seem to always be stuck on two choices when i get prioritization questions that have "INITIAL ACTION" or "MOST" or "IMMEDIATE"

for example question in Uworld asking (and this is an over simplification of the question)

Pt is Hyperkalemic (K =7) with an ST Elevation + Peaked T wave

what is the IMMEDIATE Action (I'm paraphrasing)

Choices I as stuck on were

Calcium Gluconate,

Insulin IV with Dextrose

answer: Calcium Gluconate

I understand the rationale: everything can be given to the patient because his potassium is high however calcium gluconate would be most appropriate because of it would address the cardiac issue and "hold" them until you can then admin meds that would reduce the amt of K in him.

my issue is that in a question constructed in this manner when it says Immediate, i always get stuck between two answers.

Another question in LACharity

pt is complaining of chronic pain and Complains to the charge nurse the nurses don't respond to his requests for pain. what is the nurses INITIAL Action

Choices I'm stuck on

perform complete pain assessment as well pain history

have conference with the staff nurses to assess their care

answer: have conference

What I'm getting at is: DOES ANYONE have a short hand on how to address these once you have been able to narrow it down to two choices. and I don't mean content wise.

i mean a strategy to share. pleaseeeeee
