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 D
Explanation
The correct answer is choice d. Auscultate lung fields.
Choice A rationale:
Cupping hands and tapping on the patient’s chest is part of the chest percussion technique, which helps to loosen mucus. However, it is not the first step. Before performing any physical intervention, the nurse must assess the patient’s current respiratory status.
Choice B rationale:
Positioning the patient so that the lung area to be drained is above the trachea is part of postural drainage. This step is crucial but should be done after assessing the patient’s lung fields to determine the areas that need drainage.
Choice C rationale:
Providing mouth care is important for overall hygiene and to prevent infection, especially in patients with respiratory conditions. However, it is not directly related to the immediate assessment and intervention for chest physiotherapy.
Choice D rationale:
Auscultating lung fields is the first step because it allows the nurse to assess the patient’s respiratory status and identify areas with abnormal breath sounds, which will guide the subsequent interventions like chest percussion, vibration, and postural drainage. This assessment ensures that the interventions are targeted and effective.
Correct Answer is C
Explanation
Choice A rationale:
Avoiding crossing legs at the knees is a correct practice for people with PVD. It helps to prevent constriction of blood flow in the legs. When legs are crossed, pressure is applied to the veins in the lower leg, which can impede blood flow. This can lead to several problems, including:
Increased risk of blood clots Worsening of swelling in the legs Increased pain and discomfort Potential skin damage
Reinforcing this practice with the client is important.
Choice B rationale:
Not going barefoot is also a correct practice for people with PVD. It helps to protect the feet from injuries and infections. People with PVD may have reduced sensation in their feet, making them more susceptible to injuries they may not notice. Additionally, PVD can impair wound healing, so even minor injuries can become serious problems.
Reinforcing this practice with the client is important.
Choice C rationale:
Using a thermometer to check bath water temperature is not directly relevant to PVD management. While it's generally a good safety practice to avoid excessively hot water, which can burn the skin, it's not specifically related to the blood flow issues associated with PVD.
This statement indicates a need for further teaching to focus on PVD-specific self-care measures.
Choice D rationale:
Wearing stockings with elastic tops is generally recommended for people with PVD. These stockings, often referred to as compression stockings, help to improve blood flow in the legs by applying gentle pressure. This can help to reduce swelling, pain, and the risk of blood clots.
Reinforcing this practice with the client is important.
