Discussion: Alterations in Cellular Processes
At its core, pathology is the study of disease. Diseases occur for many reasons. But some, such as cystic fibrosis and Parkinson’s Disease, occur because of alterations that prevent cells from functioning normally.
Understanding of signals and symptoms of alterations in cellular processes is a critical step in diagnosis and treatment of many diseases. For the Advanced Practice Registered Nurse (APRN), this understanding can also help educate patients and guide them through their treatment plans.
For this Discussion, you examine a case study and explain the disease that is suggested. You examine the symptoms reported and explain the cells that are involved and potential alterations and impacts.
To prepare:
- By Day 1 of this week, you will be assigned to a specific scenario for this Discussion. Please see the “Course Announcements” section of the classroom for your assignment from your Instructor.
Scenario: 27-year-old patient with a history of substance abuse is found unresponsive by emergency medical services (EMS) after being called by the patient’s roommate. The roommate states that he does not know how long the patient had been lying there. Patient received naloxone in the field and has become responsive. He complains of burning pain over his left hip and forearm. Evaluation in the ED revealed a large amount of necrotic tissue over the greater trochanter as well as the forearm. EKG demonstrated prolonged PR interval and peaked T waves. Serum potassium level 6.9 mEq/L.
By Day 3 of Week 1
Post an explanation of the disease highlighted in the scenario you were provided. Include the following in your explanation:
- The role genetics plays in the disease.
- Why the patient is presenting with the specific symptoms described.
- The physiologic response to the stimulus presented in the scenario and why you think this response occurred.
- The cells that are involved in this process.
- How another characteristic (e.g., gender, genetics) would change your response.

Expert Answer and Explanation
Alterations in Cellular Process
Role of Genes in the Disease
Genes play a significant role in substance use and addiction. McCance and Huether (2019) argue that certain genes can lead to substance use to substance addiction. The authors note that genetic factors account for 40% to 60% of vulnerability to addiction. One of the genes that often impact substance addiction is PSD-95 (Muro, 2019). The author argues that this gene is known for connecting addiction, memory, and learning. Muro (2019) conducted with mice to find the impact of PSD-95 on addiction. The authors found that the mice with a low rate of PSD-95 could not get out of the maze; instead, they went where cocaine was placed. The study concluded that mice with a higher rate of PSD-95 were highly sensitive to heroin, alcohol, cocaine, nicotine, and morphine. It can be concluded that the patient in the case scenario has a low number of PSD-95 genes making him more sensitive to hard drugs.
Reasons for Presenting Described Symptoms
The 27-year-old may have abused opioids and thus experienced unresponsiveness. According to Zhang (2019), opioid overdose can cause blue skin due to poor blood circulation, slow breathing, lessened alertness, respiratory failure, small pupils, loss of consciousness, and confusion. The authors also note that a person who has been unresponsive from taking opioids can be made conscious by giving them naloxone medication. The medication can neutralize the life-threatening depression of the central nervous and respiratory systems to regain normal breathing. The argument is evident because the patient was given naloxone and became responsive. The medication works only on people with opioid overdose. The burning pain experienced by the patient is a side effect of the naloxone. The patient fell after being unconscious, and thus he developed necrotic tissue on the greater trochanter and forearm. Serum potassium level 6.9 mEq/L shows that the patient has moderate hyperkalemia.
Physiologic Response
A physiological response can be defined as the body’s response to stimuli when in a stressful situation. Flight and fight are some of the examples of physiological response. The responses can manifest through the dry mouth, shaking, sweating, heart palpitations, panic attacks, and after breathing (Murach, Dungan, Peterson & McCarthy, 2019). The serum potassium level 6.9 mEq/L shows the effects of the opioid on the kidney. Opioids can affect the kidney by increasing the rate of potassium in the kidney. To respond to these stimuli, the patient’s body reacted by impacting his respiratory and circulatory system. Therefore, the patient lost consciousness and became unresponsive. The burning sensation was the body’s physiological response to naloxone.
Cells Involved
Clear, dark, and myoepithelial sweat cells are involved in sweat response. When the patient wants to abuse opioids, the brain will send the message to the above cells, which will then trigger sweating. The skin is also involved in a burning sensation (Murach et al., 2019). The brain’s response to naloxone often sends a message to the nerves in the skill; hence resulting in a burning sensation. Other cells involved in physiological response include brown adipose tissue (BAT) and thermogenesis.
How another Factor can Influence the Response
Genes can change the physiological response to the above stimuli. For instance, individuals with PSD-95 will be less sensitive to opioids and other hard drugs than people with a high number of PSD-95. Also, a patient without the DARPP-32 gene may not respond to opioid addiction (Abbasian, Lockington, Megharajm & Naidu, 2016).
