A nurse is caring for a patient who is postoperative following a total knee replacement. What action should the nurse take to prevent deep vein thrombophlebitis?

Choice A rationale:

A colostomy is a surgical procedure that creates an opening in the colon (large intestine) to divert stool through the abdomen. While a colostomy can affect bowel function, it does not directly increase the risk of aspiration. This is because the colon is located further down the digestive tract and does not directly involve the airway.

Choice B rationale:

An ileostomy is a surgical procedure that creates an opening in the ileum (small intestine) to divert stool through the abdomen. Similar to a colostomy, an ileostomy does not directly increase the risk of aspiration because the ileum is also located further down the digestive tract and does not involve the airway.

Choice C rationale:

Enteral feedings, also known as tube feedings, involve delivering nutrients directly into the stomach or small intestine through a tube. Patients receiving enteral feedings through a nasogastric (NG) tube are at a significantly higher risk of aspiration for several reasons:

Impaired swallowing mechanisms: Many patients who require enteral feedings have impaired swallowing mechanisms, which can increase the risk of food or liquid entering the airway instead of the esophagus.

Tube placement: The NG tube itself can potentially irritate the esophagus or interfere with the normal closure of the upper esophageal sphincter, which can increase the risk of reflux and aspiration.

Feeding formula: Enteral feeding formulas are often thin and liquid-like, which can make them easier to aspirate than thicker liquids or solid foods.

Positioning: Patients receiving enteral feedings are often in a reclined position, which can make it easier for fluids to travel back up the esophagus and into the airway.

Choice D rationale:

A chest tube is a drainage tube inserted into the chest cavity to remove air or fluid. While a chest tube can affect respiratory function, it does not directly increase the risk of aspiration. This is because the chest tube drains fluid from the pleural space, which surrounds the lungs, and does not directly involve the airway or digestive tract.

Choice A rationale:

Chronic pain can manifest in various behavioral and physical symptoms, including restlessness, pacing, grimacing, and other facial expressions of pain. These behaviors are often unconscious attempts to cope with or distract from the pain.

They may also reflect the emotional distress that often accompanies chronic pain. Patients may feel frustrated, anxious, or even depressed due to the persistent nature of their pain and its impact on their lives.

It's crucial for nurses to recognize these behavioral signs of pain, as patients may not always readily report their pain verbally. By observing these behaviors, nurses can assess the patient's pain level more accurately and provide appropriate interventions.

Choice B rationale:

Chronic pain is defined as pain that persists for longer than three months, often for much longer. It is not limited and short in duration.

This distinguishes it from acute pain, which is typically associated with an injury or illness and resolves within a few days or weeks.

Choice C rationale:

While some patients with chronic pain may have physical signs of tissue injury, this is not always the case. Chronic pain can also be caused by nerve damage, inflammation, or changes in the central nervous system.

In some cases, the underlying cause of chronic pain may be unknown.

Choice D rationale:

Although chronic pain may not always cause a significant change in vital signs, it can still be a very real and debilitating experience for patients.

Vital signs, such as heart rate, blood pressure, and respiratory rate, are often more sensitive to acute pain.

Nurses should not rely solely on vital signs to assess chronic pain. Instead, they should consider the patient's self-report of pain, behavioral cues, and other factors.
