An older woman who was recently diagnosed with end stage metastatic breast cancer is admitted because she is experiencing shortness of breath and confusion. The client refuses to eat and continuously asks to go home. Arterial blood gas results indicate hypoxia. Which intervention is most important for the nurse to implement?

A. The combination of cognitive impairment, physical injury, and restraints poses a high risk for complications such as infection, skin breakdown, and falls. Close monitoring and nursing interventions are critical to ensure safety, comfort, and appropriate care in this patient.

B. While this client may need some care for the electrolyte imbalance and nausea, this situation is more stable compared to the elderly client with Alzheimer's. The RN's role here would focus on managing the electrolyte disturbance and providing symptom relief.

C. Although this client is postoperative and may need some care, the RN's focus would primarily be on pain management and monitoring for infection or complications. However, the client’s condition is relatively stable compared to the elderly client with multiple risks.

D. This client is also stable and may require some ongoing monitoring for respiratory issues. However, the level of care needed is less intensive compared to a client with cognitive issues, restraints, and a recent fracture.

Rationale for Correct Choices:

• Bowel obstruction: The client's symptoms are classic signs of a bowel obstruction. Additionally, the lab results showing elevated sodium (165 mEq/L), low potassium (3.2 mEq/L), and low bicarbonate (20 mEq/L) suggest an electrolyte imbalance often seen in bowel obstructions due to fluid loss and impaired bowel function.
• Insert nasogastric tube: A nasogastric tube is commonly used in bowel obstruction to decompress the stomach, relieve vomiting, and prevent aspiration. It helps reduce abdominal distention and allows for drainage of the stomach contents.
• Maintain NPO status: Maintaining NPO status is essential in bowel obstruction to prevent further complications such as aspiration, vomiting, or perforation. It also helps to prepare the client for possible surgery if needed and allows the bowel to rest.
• Signs and symptoms of sepsis: Given the possibility of bowel perforation or ischemia in a bowel obstruction, monitoring for signs and symptoms of sepsis is crucial. Fever, tachycardia, and hypotension could indicate the onset of systemic infection due to bowel perforation or necrosis.
• Strict intake and output: Monitoring strict intake and output is vital to assess for dehydration or fluid imbalance, which can occur due to vomiting, diarrhea, or poor oral intake in bowel obstructions. Accurate monitoring helps guide treatment and fluid resuscitation.

Rationale for Incorrect Choices:

• Pancreatitis: Pancreatitis presents with severe upper abdominal pain that may radiate to the back, nausea, vomiting, and sometimes jaundice. There are no signs like elevated lipase or amylase levels to suggest pancreatitis.
• Food poisoning: Food poisoning can cause nausea, vomiting, and diarrhea, but it usually has an acute onset and resolves within a short period (usually a day or two). This child's symptoms have persisted for two days, and there is no mention of fever or diarrhea.
• Ruptured gallbladder: A ruptured gallbladder would present with severe right upper quadrant pain, fever, and jaundice due to bile leakage or infection. There is no indication of right upper quadrant pain or jaundice in this child.

• Culture emesis: While culturing emesis may be useful in diagnosing foodborne illnesses or infection, it is not necessary in a case of bowel obstruction. The primary intervention in bowel obstruction is relieving the obstruction and monitoring for complications.
• Prep for immediate gallbladder removal: Cholecystectomy is not indicated in this case. The client’s symptoms are not characteristic of gallbladder issues like cholecystitis or gallstone complications. The focus should be on diagnosing and managing the bowel obstruction.
• Administer oxygen via face mask: Oxygen administration is typically indicated in cases of respiratory distress or shock. While this client is experiencing discomfort, she is not showing signs of hypoxia or severe circulatory issues. Spo2 is 97% indicating adequate saturation.

• Bilirubin levels: Bilirubin levels are typically monitored when jaundice or liver dysfunction is suspected. This client does not show signs of jaundice or liver disease, and her symptoms are more consistent with a bowel obstruction.
• Rebound tenderness: Rebound tenderness is useful in cases of peritonitis or bowel perforation. However, the absence of guarding and the fact that the child is not exhibiting acute peritonitis symptoms makes rebound tenderness less relevant.
• Arterial blood gas (ABG): ABG measurements are typically used to assess respiratory and metabolic function. While the electrolyte imbalances seen in this patient (e.g., low bicarbonate) could suggest mild acidosis, ABG testing is not immediately necessary unless the client shows signs of severe metabolic disturbance or shock.
