A nurse is looking after a patient who is 12 hours postoperative following a transurethral resection of the prostate (TURP) and has a 3-way urinary catheter with continuous irrigation.
The nurse observes that there has been no urinary output in the last hour. What should the nurse do first?

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.

Choice A rationale:

Painful urination (dysuria) can be a sign of several conditions that could potentially affect the client's IVP or indicate a need for further assessment. These conditions include:

Urinary tract infection (UTI): UTIs are common in clients with recurrent kidney stones, and they can cause inflammation and pain in the urinary tract. If a client has a UTI, it's important to treat it before the IVP to reduce the risk of spreading the infection to the kidneys.

Kidney stone passage: The client's history of kidney stones makes it possible that the pain could be due to the passage of a stone. This would be important information for the healthcare team to know, as it could affect the interpretation of the IVP results.

Other urological conditions: There are other urological conditions, such as bladder or urethral strictures, that can also cause painful urination. These conditions might also need to be considered and assessed for.

It's important for the nurse to collect more data about the client's painful urination to determine the underlying cause and whether it could impact the IVP. This might include asking questions about:

The severity and duration of the pain

Any other associated symptoms, such as fever, urgency, or frequency The client's history of UTIs or kidney stones

Any recent changes in urinary habits

Based on this additional information, the nurse can then collaborate with the healthcare team to determine the best course of action, which might include:

Further assessment, such as a urinalysis or urine culture Treatment for a UTI, if present

Pain management

Rescheduling the IVP, if necessary
