In a post-surgical unit, the nurse cares for many patients experiencing pain. Which situation is likely to lower a patient’s pain threshold?
A patient who is awaiting biopsy results.
A patient who is anxious.
A patient who is having difficulty sleeping in the hospital setting.
It is the same for all patients who have had surgery.
The Correct Answer is B
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.

Correct Answer is A
Explanation
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.
Correct Answer is D
Explanation
Choice A rationale:
It is not necessary to remind a patient to avoid turning from side to side after femoral artery catheterization. Restricting movement in this way could actually increase the risk of complications such as deep vein thrombosis (DVT).
Early ambulation is generally encouraged to promote circulation and prevent blood clots.
Patients are typically allowed to turn and reposition themselves as needed for comfort, unless there are specific contraindications.
Choice B rationale:
Keeping the patient in a high-Fowler's position for 6 hours is not a standard recommendation following femoral artery catheterization.
The patient's position should be based on their individual needs and comfort level.
In some cases, a slight elevation of the head of the bed may be helpful to promote venous return, but prolonged high-Fowler's positioning is not necessary.
Choice C rationale:
Passive range-of-motion exercises are not typically performed on the affected extremity immediately following femoral artery catheterization.
This is because there is a risk of dislodging the catheter or causing bleeding at the puncture site.
Once the catheter has been removed and the puncture site has healed, gentle range-of-motion exercises may be recommended to help maintain joint mobility.
Choice D rationale:
Checking pedal pulses every 15 minutes is essential to assess for adequate circulation to the lower extremities following femoral artery catheterization.
This is because there is a risk of complications such as thrombosis or embolism, which can compromise blood flow to the legs and feet.
If the pedal pulses are weak or absent, it could indicate a serious problem that requires immediate intervention.
