Correct Answer: B

Rationale: The correct answer is B: Cerebral edema. Hypernatremia is an elevated sodium level in the blood, which can lead to osmotic shifts causing water to move out of cells, including brain cells. This can result in cerebral edema, potentially leading to neurological complications. Incorrect choices: A: Red blood cell crenation - This occurs in hypertonic solutions, not hypernatremia. C: Red blood cell hydrolysis - Hypernatremia doesn't directly cause red blood cell hydrolysis. D: Renal shutdown - Hypernatremia can stress the kidneys, but it doesn't typically lead to renal shutdown.

Incorrect choices: A: Nurse’s concerns - This is not the primary focus during a nursing health history. The nurse should prioritize understanding the patient's perspective. C: Current treatment orders - While important, this is typically addressed during the assessment phase, not specifically in the nursing health history. D: Nurse’s goals for the patient - The nurse's goals should align with the patient's goals, making understanding the patient's expectations crucial.

Correct Answer: D

Rationale: The correct answer is D: Shallow breathing and increasing lethargy. This finding could indicate a potential respiratory complication such as atelectasis or pneumonia, which are common postoperative complications. Shallow breathing can lead to inadequate oxygenation and ventilation, causing lethargy due to decreased oxygen delivery to tissues. It is crucial to assess and address respiratory issues promptly to prevent further complications. A: Abdominal pain is expected postoperatively and can be managed with pain medications. B: Serous drainage from the incision is a normal finding after surgery and indicates the wound is healing properly. C: Hypoactive bowel sounds are common after surgery due to decreased peristalsis and can be managed with interventions such as early ambulation and medications.

Rationale: The correct answer is B: 45-year old woman who has never been pregnant. This client has the highest risk of ovarian cancer due to nulliparity, which is a known risk factor. Women who have never been pregnant have a higher risk of developing ovarian cancer compared to those who have had children. Other choices are incorrect because contraceptives actually reduce the risk of ovarian cancer, having children can slightly decrease the risk, and having a child at a young age does not increase the risk significantly.
