Pt is a 67 y.o female as documented in addition to chronic smoking and malnutrition, she initially substained a right intertrochanteric hip fracture which was treated with intranadullary nailing last year. This unfortunately went on to a aseptic nonunion with subsequent screw cut out. Pt than underwent conversion to hemiarthroplasty complicated by distal femur fracture which was treated by ORIF of the distal femur. Pt was discharged to a rehab facility on chronic ceftriaxone with the plan for life long chronic suppression. Altered mental status and hypertension and leukocytesis. UA was suspicious to possible UTI. CT shows no obvious evidence but chronic perioslitis of her proximal femur. Risks for fall, left risk restriction, thrombocytosis, asymptomatic puria, lactic acidosis, chronic back pain, CVA with dysphasia presenting for septic shock, COPD, anxiety, depression, anemia, opioid use, smoking, Encephalopathy. Base the patient nursing report, medications, and labs please do the…

Vitamin D is important for bone development and maintenance because vitamin D ________.   A stimulates cells in the small intestine to absorb calcium   B is the part of the bone matrix that gives bone itÕs hardness   C is required for the osteocytes to convert sodium into calcium   D allows the skin to produce calcium when sunlight is present   E is necessary for calcium synthesis by the bone marrow

How does Parathyroid Hormone elevate blood calcium levels? by increasing the amount of CA2+ removed from the blood by the kidneys by decreasing the amount of CA2+ absorbed from the gut into the blood by increasing the number and activity of osteoclasts by increasing the number and activity of osteoblasts

Which of the following cell(s)/tissue(s) require insulin to absorb glucose? (Select all that apply) O leukocytes skeletal muscle neural tissue O adipose tissue

What will happen if you do not consume enough calcium on a particular day? If an injury occurs, the blood will not appropriately clot.   Blood calcium levels will drop.   Nerve signaling will stop, so the heart cannot beat. Blood calcium levels will remain in the normal range because calcium is released from the bone to the blood.
