A client can describe how to brush teeth but is unable to carry out the motor actions on command despite adequate strength. The motor actions appear awkward and clumsy. This presentation is MOST consistent with:

A nurse is caring for a 42-year-old client with a history of Addison’s disease who presents to the emergency department with vomiting and diarrhea for 2 days. The client reports extreme weakness and dizziness. Assessment findings: Blood pressure: 78/46 mm Hg Heart rate: 124/min Respiratory rate: 22/min Temperature: 99.1°F Skin cool and pale Capillary refill: 4 seconds Increasing confusion and lethargy Which action should the nurse take first?

Magnesium has three naturally occurring isotopes: Mg-24 (p=78.99%, m=23.985 amu) Mg-25 (p=10.00%, m=24.986 amu) Mg-26 (p=11.01%, m=25.983 amu) Calculate the average atomic mass of magnesium.  *Give numerical answer in correct significant figures.   Avg amu= [(m1p1) + (m2p2) + (m3p3) ] / 100

A male client, with a history of bipolar disorder, reports to the clinic today for a medication adjustment follow up. The client’s laboratory results reveal a blood lithium level of 1.1 mEq/L (0.6-1.2mEq/L).  The client asks the nurse, “Is that number good or bad for me?” What is the most appropriate response by the nurse:
