During the diuretic phase of ATN, the nurse should closely monitor the patient for which of the following complications?
Hypervolemia
Hyperkalemia
Hypernatremia
Hypertension
The Correct Answer is C
A. Hypervolemia: This is unlikely during the diuretic phase, as the patient is typically losing large volumes of fluid.
B. Hyperkalemia: Hyperkalemia is more common in the oliguric phase of ATN, not the diuretic phase, when potassium levels usually decrease due to fluid loss.
C. Hypernatremia: During the diuretic phase of ATN, the kidneys start to recover but may not be able to concentrate urine effectively, leading to large volumes of dilute urine. This can result in fluid and electrolyte imbalances, particularly hypernatremia (high sodium levels) due to excessive fluid loss.
D. Hypertension: Hypotension is more likely due to excessive fluid loss during the diuretic phase, not hypertension.

Correct Answer is C
Explanation
A. Dehydration: While dehydration is a possible complication in ulcerative colitis, it does not explain the symptoms of fatigue and pallor.
B. Hyperkalemia: Hyperkalemia is not typically associated with chronic blood loss and would present with symptoms like muscle weakness or arrhythmias.
C. Iron-deficiency anemia: Chronic blood loss from frequent diarrhea and ulceration of the colon in ulcerative colitis can lead to iron-deficiency anemia, causing symptoms like fatigue, dizziness, and pallor.
D. Electrolyte imbalance: While electrolyte imbalances may occur with ulcerative colitis, they do not directly cause fatigue, dizziness, and pallor related to chronic blood loss.
Correct Answer is D
Explanation
A. Apply a heating pad to the abdomen: This is incorrect and potentially harmful, as applying heat to the abdomen can increase blood flow and worsen inflammation or risk rupture of the appendix.
B. Administer a cleansing enema: Enemas should not be administered for suspected appendicitis as they may cause irritation and increase the risk of perforation.
C. Administer oral analgesics as needed: Oral analgesics are contraindicated since the patient should be NPO, and strong pain relief might mask the symptoms of a ruptured appendix.
D. Place the patient on NPO status: The highest priority preoperative intervention is to place the patient on NPO (nothing by mouth) status to prevent aspiration during anesthesia, a standard preoperative practice, especially for abdominal surgeries.
