The nurse is reviewing laboratory results for a patient scheduled for a cholecystectomy. Which result is most important for the nurse to report to the surgeon?
Blood glucose level of 90 mg/dL (5 mmol/L).
Serum creatinine level of 5 mg/dL (442 µmol/L).
Hemoglobin level of 13 g/dL (130 g/L).
Potassium level of 4 mEq/L (4 mmol/L).
The Correct Answer is B
Choice A rationale
A blood glucose level of 90 mg/dL (5 mmol/L) is within the normal range and would not need to be reported to the surgeon.
Choice B rationale
A serum creatinine level of 5 mg/dL (442 µmol/L) is significantly elevated, indicating impaired kidney function. This is a critical lab value that should be reported to the surgeon immediately, as it could impact the patient’s ability to safely undergo surgery and recover postoperatively.
Choice C rationale
A hemoglobin level of 13 g/dL (130 g/L) is within the normal range and would not need to be reported to the surgeon.
Choice D rationale
A potassium level of 4 mEq/L (4 mmol/L) is within the normal range and would not need to be reported to the surgeon.

Correct Answer is A
Explanation
The correct answer is Choice A
Choice A rationale: Crohn’s disease involves transmural inflammation of the gastrointestinal tract, often leading to hypermotility and increased peristalsis. Activity restriction reduces sympathetic stimulation, thereby minimizing intestinal motility and mechanical stress on inflamed mucosa. This helps prevent exacerbation of symptoms and promotes mucosal rest. By limiting physical exertion, the body can redirect energy toward immune modulation and tissue repair. Normal bowel motility varies, but excessive activity worsens inflammation and nutrient malabsorption in Crohn’s pathology.
Choice B rationale: While diarrhea is a common symptom in Crohn’s disease, activity restriction does not directly modulate stool frequency or water reabsorption. Diarrhea results from mucosal damage, cytokine-mediated secretion, and impaired absorption, not physical activity. Management typically involves anti-inflammatory agents, antidiarrheals, and dietary modifications. Restricting movement may indirectly reduce diarrhea by decreasing intestinal stimulation, but it is not the primary mechanism. Stool water content normally ranges from 60–85%, and inflammation disrupts this balance.
Choice C rationale: Healing in Crohn’s disease is multifactorial, involving immunosuppression, mucosal regeneration, and nutritional support. While rest contributes to systemic recovery, it is not the primary driver of mucosal healing. Healing requires suppression of TNF-alpha, IL-6, and other pro-inflammatory mediators. Activity restriction may support healing indirectly by reducing metabolic demand and stress hormone release, but pharmacologic and nutritional interventions are more central. Normal mucosal turnover occurs every 3–5 days, but inflammation delays this process.
Choice D rationale: Abdominal pain in Crohn’s disease arises from transmural inflammation, bowel distension, and neural sensitization. Although rest may reduce visceral stimulation, pain control is better achieved through anti-inflammatory therapy, bowel rest, and analgesics. Activity restriction does not directly modulate nociceptive pathways or cytokine levels. Pain perception involves complex neuroimmune interactions, and physical rest alone cannot address the underlying pathology. Normal visceral pain thresholds are altered in Crohn’s due to chronic inflammation and fibrosis.
Correct Answer is A
Explanation
Choice A rationale
Administering oxygen via a face mask is the first intervention the nurse should do. This is because the decrease in fetal heart rate after the last four contractions indicates possible fetal distress, which can be caused by insufficient oxygen. Administering oxygen to the mother can increase the amount of oxygen available to the fetus, potentially alleviating the distress.
Choice B rationale
Applying an internal fetal heart monitor can provide more accurate and continuous data about the fetal heart rate and contractions. However, this is usually not the first intervention because it is invasive and can only be done if the cervix is sufficiently dilated and the membranes have ruptured.
Choice C rationale
Using a vibroacoustic stimulator is a method used to wake a sleeping baby in the womb during a non-stress test. It is not typically used in response to signs of fetal distress during labor.
Choice D rationale
Notifying the healthcare provider is important when there are signs of fetal distress. However, the nurse has interventions, such as administering oxygen, that they can and should do immediately while the healthcare provider is being notified.
