The nurse is teaching a health promotion class for adults about the effects of sun exposure on skin. Which statement about the function of collagen is correct?

Rationale:

1. Calculate total fat calories for each day:
   • Day 1: 24×38=91224 \times 38 = 912 kJ
   • Day 2: 22×38=83622 \times 38 = 836 kJ
   • Day 3: 23×38=87423 \times 38 = 874 kJ
2. Convert total daily calories to kJ:
   • Day 1: 3,200×4.184=13,388.83,200 \times 4.184 = 13,388.8 kJ
   • Day 2: 2,980×4.184=12,471.32,980 \times 4.184 = 12,471.3 kJ
   • Day 3: 3,310×4.184=13,841.03,310 \times 4.184 = 13,841.0 kJ
3. Calculate fat percentage:
   • Day 1: (912/13388.8)×100=18.2%
   • Day 2: (836/12471.3)×100=17.1%
   • Day 3: (874/13841.0)×100=17.3%

Average fat percentage: (18.2+17.1+17.3)/3=17.5%

1. Interpretation:
   • The recommended fat intake range is 20-35% of total calories.
   • The client's fat intake is 14-19%, which is below the recommended range.
   • The client should increase his fat intake to meet nutritional needs.

A. Auscultate for bowel sounds. While monitoring for postoperative ileus is important, it is not the priority intervention in a patient who is suddenly confused and lethargic after hip surgery. Avascular complications, fat embolism, or deep vein thrombosis (DVT) are more immediate concerns.
B. Compare pedal pulses bilaterally. A sudden change in mental status after hip arthroplasty could indicate a fat embolism or deep vein thrombosis (DVT) leading to pulmonary embolism. Comparing bilateral pedal pulses helps assess for signs of vascular impairment or embolic complications, which are serious postoperative risks. Fat embolism syndrome (FES) can cause confusion, lethargy, and respiratory distress, requiring immediate intervention.
C. Observe the surgical incision. While assessing for infection or bleeding is important, these complications do not typically cause sudden confusion and lethargy. Systemic embolic events or impaired circulation are more critical to assess first.
D. Assess mobility of the right leg. Evaluating mobility is part of routine post-arthroplasty care, but it does not directly address the sudden mental status changes seen in this patient. Assessing circulation and embolic risk takes priority.
