Correct Answer is B

Explanation

Choice A rationale

Genetic predisposition to gain weight. Genetics do play a significant role in obesity, but they are only one part of a multifactorial condition that involves numerous other factors, including environment and lifestyle.

Choice B rationale

Many complex physiologic and psychosociocultural factors. Obesity results from a complex interplay of genetic, metabolic, behavioral, and environmental factors. It includes influences from diet, physical activity, cultural attitudes, and psychological factors, making it a multifaceted condition.

Choice C rationale

Energy intake exceeding energy output. While an imbalance between energy intake and expenditure is a fundamental aspect of weight gain, it alone does not account for the complexity of obesity, which also involves hormonal, genetic, and psychosocial factors.

Choice D rationale

Fat cells being able to increase their size indefinitely. While fat cells can expand to store more fat, this explanation is too simplistic to account for the multifaceted nature of obesity, which includes genetic, metabolic, behavioral, and environmental factors.

A. Offer cups of fruit juices at frequent intervals. B. Irrigate and reposition the NGT frequently. C. Remind the client that PCA use may slow the return of bowel function. D. Have the client splint the surgical site while deep breathing and coughing.

Correct Answer is D

Explanation

Choice A rationale

Offering cups of fruit juices at frequent intervals is not recommended immediately postoperatively due to the risk of nausea and vomiting. The client should start with clear liquids and gradually progress.

Choice B rationale

Irrigating and repositioning the nasogastric tube frequently is not recommended as it can cause discomfort and dislodge the tube. Proper fixation and periodic checking are preferred.

Choice C rationale

Reminding the client that PCA use may slow the return of bowel function is not accurate. While opioids can slow bowel motility, PCA use is for pain management and should be monitored, not discouraged.

Choice D rationale

Having the client splint the surgical site while deep breathing and coughing helps prevent atelectasis and promotes lung expansion. It also reduces pain and protects the surgical incision during respiratory exercises. .
