Which of the following statements accurately reflects the relationship between obesity and surgical risk?
Obesity only affects the risk of surgical complications in certain surgical procedures.
Obesity has no impact on surgical risk.
Obesity decreases the risk of surgical complications.
Obesity increases the risk of surgical complications.
The Correct Answer is D
A. Obesity does not selectively affect only certain types of surgical procedures; rather, it generally increases the risk of complications across a wide range of surgical interventions. This includes both elective and emergency surgeries.
B. Obesity significantly impacts surgical risk. It is associated with a higher likelihood of complications such as wound infections, delayed wound healing, respiratory problems, and cardiovascular issues. The presence of excess body fat affects multiple physiological systems and can complicate both the surgical procedure and recovery.
C. Obesity does not decrease the risk of surgical complications; rather, it increases it. The excess body fat associated with obesity can lead to problems such as impaired wound healing, increased risk of infection, cardiovascular strain, and respiratory issues, which all contribute to a higher risk of complications during and after surgery.
D. This statement accurately reflects the relationship between obesity and surgical risk. Obesity is associated with an increased risk of a variety of surgical complications.

Correct Answer is B
Explanation
A. While a slightly elevated hematocrit can be associated with dehydration, it's not as specific as urine specific gravity.
B. This indicates concentrated urine, which is a classic sign of dehydration. Normal urine specific gravity is typically between 1.005 and 1.030.
C. This is a normal creatinine level and does not indicate dehydration.
D. This is within the normal range for sodium.
Correct Answer is B
Explanation
A. Increasing sodium intake would exacerbate hypernatremia, not correct it. Hypernatremia is characterized by an excess of sodium in the blood, so the goal of treatment is to lower sodium levels, not increase them.
B. Infusing hypotonic IV fluids, such as 0.45% NaCl or D5W (5% dextrose in water), helps to dilute the high sodium concentration in the blood and can assist in correcting hypernatremia. Hypotonic fluids move water into cells and help balance the sodium levels by promoting hydration and lowering the sodium concentration.
C. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia (elevated potassium levels), not hypernatremia. It works by exchanging potassium for sodium in the gastrointestinal tract and would not address hypernatremia.
D. Implementing a fluid restriction is generally not the best approach for treating hypernatremia. In fact, fluid restriction could worsen hypernatremia by limiting the client's fluid intake and not addressing the sodium imbalance. The primary goal in hypernatremia is usually to rehydrate the patient with appropriate fluids.
