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?

A. Increase in protein requirements: Protein needs may slightly increase with age to maintain muscle mass, but this does not directly cause weight gain. Instead, inadequate protein may contribute to muscle loss.

B. Increase in fluid requirements: Older adults typically have decreased thirst sensation, not increased fluid needs. Weight gain is not directly linked to hydration needs but more to energy balance.

C. Decrease in vitamin intake: While older adults may have reduced vitamin intake due to dietary changes, this affects micronutrient status rather than causing significant weight gain.

D. Decrease in muscle mass: Sarcopenia, the loss of muscle mass with aging, lowers basal metabolic rate. This decreases calorie expenditure, making it easier to gain weight even with unchanged food intake.

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.
