A nurse is assessing a patient with a surgical wound healing by secondary intention. Which finding should the nurse report to the charge nurse?

Choice A rationale:

The spinal cord plays a crucial role in pain transmission, but it does not initiate the afferent pathways. It receives pain signals from nociceptors and relays them to the brain for processing.

The spinal cord is also involved in pain modulation, as it can dampen or amplify pain signals depending on various factors. However, it is not the primary trigger for pain sensation. That role belongs to nociceptors.

Choice B rationale:

Nociceptors are specialized sensory receptors that detect potentially damaging stimuli, such as intense heat, pressure, or chemical irritants.

They are located throughout the body, including the skin, muscles, joints, and internal organs.

When nociceptors are activated, they generate electrical signals that travel along nerve fibers to the spinal cord and brain. This process initiates the afferent pathways, which ultimately lead to the conscious perception of pain.

Nociceptors are essential for protecting the body from harm. They alert us to potential dangers and trigger responses that help us avoid injury or further damage.

Choice C rationale:

Endorphins are natural pain-relieving substances produced by the body. They act on receptors in the brain and spinal cord to reduce pain perception.

However, endorphins do not trigger the afferent pathways. They work by modulating pain signals that have already been initiated by nociceptors.

Choice D rationale:

The cortex is the outer layer of the brain that is responsible for higher-level functions, such as thinking, feeling, and decision- making.

It plays a role in the conscious experience of pain, but it does not trigger the afferent pathways.

The cortex receives pain signals from the spinal cord and processes them, leading to the awareness of pain.

Choice A rationale:

Paralytic ileus is a common postoperative complication that occurs when the normal movement of the intestines (peristalsis) is slowed or stopped. This can lead to a buildup of gas and fluids in the intestines, causing abdominal distention, nausea, vomiting, and constipation. The absence of bowel sounds, abdominal distention, and the inability to pass flatus are all classic signs of paralytic ileus.

Here are some of the factors that can contribute to paralytic ileus: Manipulation of the intestines during surgery

Anesthesia

Pain medications, especially opioids Electrolyte imbalances

Dehydration

Underlying medical conditions, such as diabetes or kidney disease Treatment for paralytic ileus typically involves:

Resting the bowel by not eating or drinking anything by mouth

Using a nasogastric (NG) tube to suction out gas and fluids from the stomach Providing intravenous (IV) fluids and electrolytes

Encouraging early ambulation

Using medications to stimulate bowel movement, such as metoclopramide or erythromycin

Choice B rationale:

Incisional infection is an infection of the surgical wound. It would typically present with redness, warmth, swelling, and pain at the incision site. The patient may also have a fever. While incisional infections can occur after abdominal surgery, they are not typically associated with the absence of bowel sounds, abdominal distention, and the inability to pass flatus.

Choice C rationale:

Fecal impaction is a severe form of constipation in which a large, hard mass of stool becomes trapped in the rectum. It can cause abdominal pain, bloating, and difficulty passing stool. However, it is not typically associated with the absence of bowel sounds or abdominal distention.

Choice D rationale:

Health care-associated Clostridium difficile (C. difficile) is a bacterial infection that can cause severe diarrhea, abdominal pain, and cramping. It is often associated with antibiotic use. While C. difficile can occur after abdominal surgery, it is not typically associated with the absence of bowel sounds, abdominal distention, and the inability to pass flatus.
