A nurse is caring for a group of patients on an adult medical-surgical unit.
Which patient should the nurse identify as having the highest risk for aspiration?
A patient who has a colostomy
A patient who has an ileostomy
A patient receiving enteral feedings through an NG tube
A patient who has a chest tube following a motor vehicle crash
The Correct Answer is C
Choice A rationale:
A colostomy is a surgical opening in the abdomen that allows stool to pass through the colon and out of the body. While a colostomy may increase the risk of certain complications, such as dehydration and skin irritation, it does not directly increase the risk of aspiration. This is because the colostomy bypasses the upper digestive tract, where aspiration typically occurs.
Choice B rationale:
An ileostomy is a similar surgical opening in the abdomen, but it diverts the small intestine rather than the colon. Like a colostomy, an ileostomy does not directly increase the risk of aspiration. However, it may lead to dehydration and electrolyte imbalances, which could indirectly contribute to aspiration risk.
Choice C rationale:
Enteral feedings through an NG tube are a common way to provide nutrition to patients who cannot eat by mouth. However, these feedings can also increase the risk of aspiration. This is because the NG tube bypasses the normal swallowing mechanisms, which help to protect the airway. If the feeding tube is not properly positioned or if the patient has impaired gastric motility, formula could enter the lungs and cause aspiration pneumonia.
Choice D rationale:
A chest tube is a drainage tube that is inserted into the chest cavity to remove air or fluid. While a chest tube may cause some discomfort and respiratory issues, it does not directly increase the risk of aspiration.

Correct Answer is B
Explanation
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.
Correct Answer is C
Explanation
Choice A rationale:
Irrigating the tubing with sterile normal saline solution is not a routine part of closed-wound drainage system care.
It's usually only done if there's evidence of a blockage or infection, and only under the direction of a healthcare provider. Unnecessary irrigation could introduce bacteria into the system and increase the risk of infection.
It could also disrupt the delicate balance of fluids in the wound and delay healing.
Choice B rationale:
Replacing the drainage plug after releasing hand pressure on the device is not correct. The drainage plug should actually be replaced before releasing hand pressure.
This is to prevent air from entering the system, which could disrupt the vacuum and impair drainage.
Choice D rationale:
Emptying the reservoir once per day is not frequent enough.
The reservoir should be emptied whenever it becomes full, which could be more often than once a day, depending on the amount of drainage.
Allowing the reservoir to become too full could put pressure on the wound and impede healing.
Choice C rationale:
Fully re-collapsing the reservoir after emptying it is essential to maintain the vacuum that promotes drainage. If the reservoir is not fully re-collapsed, the vacuum will be lost, and drainage will slow or stop.
This could lead to fluid accumulation in the wound, which could increase the risk of infection and delay healing.
