A nurse is planning to monitor a client for dehydration following several episodes of vomiting and an increase in the client’s temperature.
Which of the following findings should the nurse identify as an indication that the client is dehydrated?

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.

Choice A rationale:

Awaiting biopsy results can certainly cause anxiety and stress, but it doesn't directly impact the physiological mechanisms that modulate pain perception.

While a patient awaiting biopsy results may be more attentive to their bodily sensations, including pain, the anxiety itself is not the primary driver of a lowered pain threshold.

It's important to address the patient's concerns and provide emotional support, but this alone may not be sufficient to manage pain effectively if anxiety is not the primary factor.

Choice B rationale:

Anxiety activates the sympathetic nervous system, which triggers the "fight-or-flight" response. This cascade of physiological changes includes:

Increased heart rate and blood pressure Muscle tension

Dilated pupils

Heightened awareness of bodily sensations

These physiological changes can amplify pain signals and lower the pain threshold, meaning that a person who is anxious may perceive pain more intensely than someone who is calm and relaxed.

This is because anxiety can reduce the effectiveness of the body's natural pain-inhibiting mechanisms, such as the release of endorphins and serotonin.

Choice C rationale:

Difficulty sleeping can also contribute to pain, but its effect on pain threshold is less direct than that of anxiety. Sleep deprivation can lead to:

Increased irritability Decreased pain tolerance Impaired cognitive function

These factors can make it more difficult to cope with pain, but they don't directly lower the threshold at which pain signals are perceived.

Choice D rationale:

Pain threshold varies among individuals due to a variety of factors, including: Genetics

Past experiences with pain Psychological factors Cultural beliefs

Coping mechanisms

It is incorrect to assume that all patients who have had surgery will have the same pain threshold.
