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.

Answer and Explanation

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 B

Explanation

Choice B rationale:

Checking the patency of the tubing is the first and most crucial step in addressing the lack of urinary output in this patient. Here's a detailed explanation of why this is the priority action:

Addresses the Most Likely Cause: Obstruction of the urinary catheter tubing is the most common and easily reversible cause of sudden cessation of urinary output in a patient with a continuous bladder irrigation system.

Prevents Complications: A blocked catheter can lead to a number of serious complications, including: Bladder distention, which can cause pain, discomfort, and potential bladder damage.

Urinary retention, which can increase the risk of urinary tract infections (UTIs) and kidney damage. Hematuria, or blood in the urine, due to clot formation in the bladder or catheter.

Non-Invasive Intervention: Checking the tubing is a simple, non-invasive procedure that can quickly identify and resolve the issue without requiring further interventions or delays in care.

Prioritizes Patient Safety: It's essential to promptly address any potential urinary obstruction to prevent the aforementioned complications and ensure patient safety.

Rationale for Other Choices:

Choice A: Administering a prescribed analgesic:

While pain management is important, it does not directly address the lack of urinary output. Pain medication would be appropriate if pain were assessed to be the cause of the decreased output, but it's not the first priority in this situation.

Choice C: Notifying the provider:

Although the provider should be informed of the situation, checking the tubing for patency is a necessary first step to gather more information and potentially resolve the issue quickly without requiring further intervention.

Choice D: Offering oral fluids:

Increasing fluid intake might be helpful in some cases of decreased urinary output, but it's not the priority action in a patient with a continuous bladder irrigation system and a potential catheter obstruction.

A. Recap needles and place them in a wastebasket. B. Do not recap the needle on an ABG specimen. C. Place uncapped needles in a puncture-proof container after use. D. Break needles in half before putting them in the sharps disposal box.

Correct Answer is C

Explanation

Choice A rationale:

Recapping needles is a dangerous practice that significantly increases the risk of needlestick injuries.

The act of recapping involves directing the sharp end of the needle towards one's hand, creating a high likelihood of accidental puncture.

Even experienced healthcare professionals are susceptible to needlestick injuries during recapping.

Wastebaskets are not designed for the safe disposal of sharps and can easily be punctured, leading to potential exposure to bloodborne pathogens.

Choice B rationale:

While it is true that needles should not be recapped on ABG specimens, this option does not address the broader issue of safe needle disposal in general.

Focusing solely on ABG specimens could lead to the misconception that recapping is acceptable for other types of needles.

Choice D rationale:

Breaking needles in half is not recommended as a standard practice for needle disposal.

This action can create sharp fragments that are difficult to handle and can still cause injuries.

Sharps disposal containers are designed to safely contain intact needles and should be used as the primary method of disposal.

Choice C rationale:

Placing uncapped needles directly into a puncture-proof container is the safest and most recommended practice for needle disposal.

These containers are specifically designed to prevent needlestick injuries by shielding the sharps from accidental contact. They are typically made of hard plastic or metal and are clearly labeled for biohazard waste.

Using puncture-proof containers consistently for all needle disposal significantly reduces the risk of needlestick injuries among healthcare workers.
