The atp solution that you used in your muscle contraction procedure contains magnesium ions, which increase the strength of contraction in glycerinated muscle. in living muscle cells, magnesium ions compete with calcium ions for binding sites on troponin molecules. in the condition of hypermagnesemia—a high concentration of magnesium ions in the blood—magnesium ions can prevent calcium ions from binding troponin. would this strengthen, weaken, or have no effect on the muscle contraction? explain.

After entering a client's room and introducing yourself, you review the client's medical record. the client's name is elizabeth jones, the same name as a client you took care of yesterday. what step should you take to ensure the patient you are treating is the same elizabeth jones referenced in the client's medical record? a. confirm the client's identity with a fellow home health aide. b. ask the client to repeat her name a minimum of two more times. c. call the client's daughter to confirm the client's name is actually elizabeth jones. d. check the client's wrist for a wristband with a patient number and/or bar code that corresponds with the client's medical record.
