A client who is having gastrointestinal (GI) difficulties is undergoing diagnostic procedures.

The client asks the nurse about the difference between ulcerative colitis and Crohn's disease.

Which information should the nurse offer?

A) Incorrect- Reviewing transcutaneous bilirubin levels is unrelated to the presence of an enlarged clitoris. Bilirubin levels are typically assessed to monitor jaundice in newborns.
B) Incorrect- Observing and palpating breast tissue for enlargement is not relevant to the condition of salt-wasting congenital adrenal hyperplasia. Breast tissue enlargement would not be associated with this hormonal disorder.
C) Incorrect- Assessing for signs of fluid retention and bilateral pedal edema is important for monitoring for other conditions, but it is not relevant to the enlarged clitoris seen in this specific scenario.
D) Correct- Salt-wasting congenital adrenal hyperplasia is a genetic disorder that results in a deficiency of certain enzymes required for cortisol and aldosterone production. This deficiency leads to an overproduction of androgens, which can cause virilization of female external genitalia. The enlarged clitoris is a result of increased androgen levels. Explaining this finding to the mother provides her with accurate information about the condition and its effects on the infant's anatomy.

The correct answer is Choice D

Choice A rationale: Splinting with a pillow may reduce discomfort during movement or coughing by stabilizing the incision site, but it does not address acute postoperative pain with sympathetic overdrive. The elevated heart rate, respiratory rate, and blood pressure suggest a stress response mediated by catecholamines. Without analgesia, nociceptive signals continue to activate the hypothalamic-pituitary-adrenal axis. While splinting is supportive, it lacks the pharmacologic efficacy needed to blunt nociceptive transmission at the spinal or supraspinal level.

Choice B rationale: Assessing IV patency is a procedural prerequisite for medication administration but not a therapeutic intervention in itself. It does not directly address the pathophysiology of acute pain or the sympathetic surge evidenced by tachycardia and hypertension. Pain activates ascending pathways via A-delta and C fibers, requiring pharmacologic blockade. IV access assessment is necessary but secondary to the urgent need for analgesia to prevent complications like hypoxia, hyperventilation, or delayed recovery.

Choice C rationale: High Fowler positioning may improve diaphragmatic excursion and reduce pulmonary complications, but it does not mitigate visceral or incisional pain. In fact, increased intra-abdominal pressure from upright posture may exacerbate pain at the surgical site. Pain perception involves central sensitization and peripheral nociceptor activation, which are unaffected by positioning. The client’s pale skin and elevated vitals indicate systemic distress requiring analgesic intervention, not postural adjustment. Thus, this choice lacks direct analgesic benefit.

Choice D rationale: IV analgesics act rapidly to inhibit nociceptive transmission at the spinal cord and brainstem levels. Opioids bind to mu receptors, reducing neurotransmitter release and hyperpolarizing neurons, thereby dampening pain signals. This intervention directly targets the physiologic cause of elevated heart rate, respiratory rate, and blood pressure. Normal heart rate is 60–100 bpm, respiratory rate 12–20 breaths/min, and BP <120/80 mmHg. Prompt analgesia prevents complications like hypoxia, delayed healing, and neuroendocrine stress
