A nurse is applying cold therapy to a client's face following oral surgery. The nurse should identify that which of the following is a therapeutic effect of cold therapy?
Increased tissue metabolism
Reduced blood coagulation
Decreased edema formation
Improved blood flow
The Correct Answer is C
A. Increased tissue metabolism: Cold therapy slows tissue metabolism by reducing enzymatic activity and cellular function, which helps minimize inflammation and tissue damage, not increase metabolism.
B. Reduced blood coagulation: Cold therapy typically promotes vasoconstriction, which supports blood clotting rather than reducing coagulation. This effect can help control minor bleeding after surgery.
C. Decreased edema formation: Cold therapy causes vasoconstriction, which limits fluid accumulation in tissues and reduces capillary permeability, leading to less swelling and edema formation at the surgical site.
D. Improved blood flow: Cold causes vasoconstriction, which decreases blood flow temporarily. This helps limit inflammation and edema but does not enhance circulation during application.

Correct Answer is A
Explanation
A. Brittle hair: Malnutrition often leads to protein and micronutrient deficiencies, which impair hair growth and texture, resulting in dry, brittle, or thinning hair. This is a common visible sign in clients with poor nutritional status.
B. Yellow conjunctivae: Yellowing of the conjunctivae typically indicates jaundice due to liver dysfunction or hemolysis, not malnutrition from inflammatory bowel disease. It reflects bilirubin accumulation rather than nutrient deficiency.
C. Bradycardia: While bradycardia may occur in severe starvation or electrolyte imbalance, it is not a consistent or early indicator of malnutrition from inflammatory bowel disease. It requires further context to be clinically relevant.
D. Clubbing of the fingernails: Clubbing is associated with chronic hypoxia or pulmonary/cardiac conditions. It is not commonly linked to malnutrition or inflammatory bowel disease unless there are severe complications such as chronic anemia or hypoxia.
Correct Answer is C
Explanation
A. Wheelchair is on the left side, which is the postoperative knee, risking strain or injury to the healing limb during transfer. Not ideal for maximizing client safety and independence in mobility.
B: Wheelchair is placed at the head of the bed, making it impractical and unsafe for transfer. No clear pivot point, and body mechanics would be compromised for both the nurse and the client.
C. The wheelchair is positioned on the client's right side, which is the unaffected leg, allowing the client to pivot and transfer using their stronger limb. This placement minimizes strain on the left surgical knee, which reduces pain and risk of injury.
