Corrected entry: Tony could not have the head band control on the boat to control the mark 42, he did not have anything when he got to the Mandarin's place.
Corrected entry: Pepper is in hospital with an IV line in her arm. A nurse comes in and injects a drug into the line. The problem is: The nurse doesn't kink the line above where she injects, which means the drug can go up the line and into the IV bag as well as going down the line. When a drug is ordered IV, the doctor who ordered the drug wants it to go in quickly, not slowly from the bag or upper tubing.
Correction: IV lines have reflux valves. You never have to "kink" the line for the medication to go only to the patient. Secondly she's not in a hospital, she's imprisoned at a ship yard, so there isn't a doctor or a nurse. Just a guy in a collared shirt and pants. Lastly "the doctor" doesn't want you to bolus (push in quickly) all medications, eg. Adenosine should be pushed over 6 min. If you bolus adenosine it will stop your heart. Pain medications are pushed in over 2 min, and usually bolused in to the IV line port (which again does not need to be kinked) The dripping IV fluid will push it in slowly, preventing that head rush junkies love.
Correction: The control unit is stored in the helmet, which flew to him with the rest of the suit.
Absolutely wrong there is no room inside the helmet for the control.
The Mark XLII Telepresence Headset is quite small. There is absolutely enough room within the helmet of the Mark XLII armour for it to be stored.
With the shots that we get from inside the helmet we can see that there is a small space around his head. This would be to aid in the cushioning of gunshots to the head. There would be enough space for this to headset to fit as it is most likely the device that projects his HUD to the inside of the helmet every time that he uses one of his suits. So would need to be present in most if not all of them.
