Blood test, or any test performed in the emergency department depend entirely on the patient’s presenting symptom and the physician’s interpretation of what the source may be of the patient’s condition. If your father has a history of migraines and his headache was identical or quite similar to previous headaches, the physician may not have run any tests and simply have treated the headache. If there was a concern that infection was the source he would have run a panel of labs and if he was concerned that some type of structural problem (mass, bleeding) may be the source of the problem, he would have ordered various types of imaging depending on what he was looking for.

Since all of these test have associated costs, physicians attempt to appropriately order test when they believe there is a true likelihood of a given disease process or a disease process that cannot be sorted out without testing. Migraine headaches are often diagnosed by clinical presentations, history and physical exam alone.

Your symptoms are concerning for a serious abdominal issue and you should present to you should call your regular doctor or go to the emergency room. There are many things that could possibly be causing your symptoms: from simple irritations of your intestines all the way to a ruptured appendix. Abdominal complaints that progress and get worse beyond 12-24 hours should be evaluated by a physician and are notoriously difficult to diagnose without an actual physician’s examination and possibly lab tests and medical imagine as determined by that physician.

The very first step is to call 911. You want to initiate getting trained medical professionals to that person as quickly as possible and then having those professionals transport that person to an emergency department. Our EMS professionals, Fire - EMS - Police are trained and drill in critical life saving steps needed top provide the most life sustaining outcomes.
Personally, the greatest thing you could do now is to take a CPR course offered by the American Red Cross ( https://www.redcross.org/take-a-class/cpr ) or from the American Heart Association (http://cpr.heart.org/AHAECC/CPRAndECC/FindACourse/UCM_473162_Find-A-Course.jsp ). These are excellent, state of the art courses that will provide the tools needed to provide the best care possible out-side-of-a-hospital for an individual suffering from a heart attack.
Finally, in general, until help arrives: place the person in a safe comfortable place, work on getting them to calm down and to breath comfortable and easily. Loosen any tight restrictive clothing and if they have medication for their heart that they are supposed to take (generally a small nitroglycerin pill that goes under their tongue) help them take that medication. They're likley to vomit so only a sip of water at best and otherwise nothing to eat or drink. Thats about the best you can do without CPR training, which is the next thing you should do now to increase the odds of a good outcome, if necessary, in the future.

Being hit in the head absolutely can cause a seizure. If the person has a pre-existing seizure disorder the trauma may cause a seizure through the concussive forces. If the person does not have a pre-existing seizure disorder a seizure indicates a severe disruption of the neural process and the individual should be evaluated by a physician rapidly, generally in the emergency room. Cerebral bleeding (bleeding in the space where the brain rests) is the most threatening concern for head trauma that results in seizure like activity. The concern is that the brain sits in a closed space (the bony skull) with no way to accommodate the expansion caused by the extra blood. This is a life threateneing process with the brain being compressed and needs emergent neurological intervention (they need surgery to decompress the pressure on the brain and then on going pressure monitoring in an ICU setting). Evan if bleeding has not occurred, a seizure after trauma to the head indicates severe injury to the brain (a Concussion or Traumatic Brain Injury) and MUST have on going medical care to assure the best recovery from the injury.

It's excellent that you are proactively preparing yourself to be ready if anyone should ever need help. Here would be the critical first steps:

First, get the person out of the water -

Throw them a rescue buoy, ring, float, or life vest to allow the person to remain on top of the surface. If the person is close by, use a pole, rope, etc., that could be used to pull the person to land or the side of the pool. Importantly, if you do not know how to swim AND the water is over your head, do NOT enter the water yourself as struggling drowning individuals frequently drown the rescuer who is not trained in swimming water rescue. If you are not trained in swimming water rescue, seek the closest help available. Rest assured, if your children are in lessons, they will be well protected.

Second, drowning resuscitation -

This follows CPR guidelines that can be found on line in the American Red Cross (www.redcross.org/take-a-class/cpr/cpr-training) or the American Heart Association (http://cpr.heart.org/AHAECC/CPRAndECC/FindACourse/UCM_473162_Find-A-Course.jsp).
Here is the basic CPR link from the ARC website which is well written and clearly stated. As you will see, the keys are opening the airway, generally by using a jaw thrust. Rescue breathing using mouth-to-mouth breaths, and, if needed, CPR with chest compressions (https://www.redcross.org/take-a-class/cpr/performing-cpr/cpr-steps).

In summary, 1. use the tools available on site to remove the individual from the water; 2. follow the basic CPR steps.
For you, I see the next critical step is taking a basic CPR course as outlined above.
