The patient is a 65-year-old male admitted to the medical surgical unit after a total cholecystectomy.
He has a past medical history of hypertension, heart failure, type 1 diabetes mellitus, cholelithiasis, and cholangitis. Which physician orders would the nurse anticipate being prescribed after reporting findings? Select all that apply.
Stat ventilation/perfusion (V/Q) of chest.
Place patient on oxygen 2 to 4 liters and maintain oxygen saturation at or above 95%.
Stat 2 views chest x-ray.
Send sputum for culture & sensitivity stat.
Complete blood count (CBC), basic metabolic panel (BMP), and blood cultures.
Start the patient on antibiotic therapy.
Correct Answer : B,C,E,F
B. Place patient on oxygen 2 to 4 liters and maintain oxygen saturation at or above 95%.
Rationale:
Hypoxemia: Patients who have undergone cholecystectomy are at risk for developing hypoxemia due to various factors, including:
Atelectasis: Collapsed lung tissue can impair gas exchange, leading to low oxygen levels in the blood.
Pneumonia: A potential post-operative complication that can cause inflammation and fluid buildup in the lungs, hindering oxygen uptake.
Pain: Post-surgical pain can inhibit deep breathing and coughing, which are essential for maintaining adequate lung function.
Oxygen Therapy: Supplementing oxygen helps to increase oxygen saturation and improve overall tissue oxygenation, reducing the strain on the heart and other organs.
Oxygen Saturation Goal: Maintaining oxygen saturation at or above 95% ensures that the patient's tissues are receiving sufficient oxygen to meet their metabolic needs.
C. Stat 2 views chest x-ray.
Rationale:
Chest X-ray: A valuable diagnostic tool that can visualize the lungs and surrounding structures, aiding in the assessment of: Atelectasis: Appears as areas of increased density on the x-ray, indicating collapsed lung tissue.
Pneumonia: May present as consolidation (solid white areas) or infiltrates (patchy areas of increased density) on the x-ray. Pleural effusion: Fluid accumulation in the pleural space, which can impair lung expansion and gas exchange.
Pneumothorax: Presence of air in the pleural space, which can cause lung collapse and respiratory distress.
Early Detection: Prompt identification of respiratory complications through chest x-ray allows for timely interventions and prevents further deterioration of the patient's condition.
E. Complete blood count (CBC), basic metabolic panel (BMP), and blood cultures.
Rationale:
CBC: Assesses for signs of infection or inflammation, including:
Elevated white blood cell count (leukocytosis) Increased neutrophils (neutrophilia)
Anemia (low red blood cell count)
BMP: Evaluates electrolyte and kidney function, which can be affected by infections and post-operative complications.
Blood Cultures: Determines the presence of bacteria in the bloodstream, allowing for identification of the causative organism and guiding appropriate antibiotic therapy.
F. Start the patient on antibiotic therapy.
Rationale:
Infection Risk: The patient's history of cholangitis and recent surgery increase the risk of infection. Prophylactic Antibiotics: Often administered after cholecystectomy to prevent post-operative infections.
Early Intervention: Prompt initiation of antibiotic therapy is crucial in managing infections and preventing serious complications such as sepsis.

Correct Answer is A
Explanation
Rationale for Choice A:
Direct (sliding) hiatal hernias: These are the most common type of hiatal hernia. They occur when the upper part of the stomach slides upward through the diaphragm into the chest cavity. This displacement disrupts the normal function of the lower esophageal sphincter (LES), which is a ring of muscle that acts as a valve between the esophagus and stomach. The LES is responsible for preventing stomach contents from refluxing back into the esophagus.
Esophageal reflux: When the LES is weakened or impaired, stomach acid, pepsin, and bile can flow back into the esophagus, causing a burning sensation known as heartburn, regurgitation of food or sour liquid, and irritation of the esophageal lining.
Prevention of esophageal reflux: Nursing actions aimed at preventing esophageal reflux are crucial in the management of hiatal hernias. These actions include:
Elevate the head of the bed: This helps to keep stomach contents below the level of the esophagus, reducing the risk of reflux. Avoid eating large meals: Large meals put more pressure on the stomach, which can increase the likelihood of reflux.
Avoid lying down after eating: Lying down can allow stomach contents to flow back into the esophagus more easily. Avoid foods that trigger reflux: Common triggers include fatty foods, spicy foods, acidic foods, caffeine, and alcohol.
Maintain a healthy weight: Excess weight can increase abdominal pressure and contribute to reflux.
Consider medications: If lifestyle changes are not enough to control reflux, medications such as antacids, H2 blockers, or proton pump inhibitors may be prescribed.
Rationale for Choice B:
Maintaining intact oral mucosa: This is not a primary goal in the care of a client with a hiatal hernia. While oral hygiene is important for overall health, it does not directly address the issue of esophageal reflux.
Rationale for Choice C:
Increasing intestinal peristalsis: This is not a relevant goal for a hiatal hernia. Hiatal hernias primarily affect the upper digestive tract, not the intestines.
Rationale for Choice D:
Promoting effective swallowing: This is not the most important goal in the care of a client with a hiatal hernia. While swallowing difficulties can occur in some cases, they are not the primary concern. The priority is to prevent esophageal reflux and its associated complications.
Correct Answer is A
Explanation
Choice A rationale:
Lactulose directly addresses the primary cause of hepatic encephalopathy, which is the accumulation of ammonia in the blood. Ammonia is a neurotoxin that can impair brain function, leading to confusion, lethargy, and even coma. Lactulose works by trapping ammonia in the colon, where it can be safely excreted in the stool. This decrease in ammonia levels in the blood allows for the improvement of mental status.
Studies have consistently shown that lactulose therapy can significantly improve mental function in patients with hepatic encephalopathy. This improvement is often seen within a few days of starting treatment.
The nurse should assess the client's mental status regularly to monitor for improvement. This assessment should include evaluating the client's level of consciousness, orientation, attention, memory, and speech.
Improved mental status is a critical therapeutic goal in the treatment of hepatic encephalopathy. It allows patients to regain their independence and participate more fully in their care.
Choice B rationale:
While lactulose can cause diarrhea, which may lead to a slight increase in urine output, this is not the primary therapeutic response that the nurse should expect.
The increase in urine output is typically secondary to the diarrhea and does not directly reflect a reduction in ammonia levels or improvement in mental status.
Choice C rationale:
Lactulose does cause diarrhea, which is a common side effect of the medication.
However, the goal of lactulose therapy is not to reduce the number of liquid stools but rather to trap ammonia in the colon and promote its excretion.
The nurse should monitor the client's stool frequency and consistency to ensure that they are not experiencing excessive diarrhea, which could lead to dehydration and electrolyte imbalances.
Choice D rationale:
While improved mental status may eventually lead to improved mobility, it is not the most immediate or direct therapeutic response that the nurse should expect from lactulose therapy.
The ability to ambulate independently is more likely to be a long-term goal of treatment, rather than an immediate response to lactulose.
