Module 6: Endocrine pathophysiology Purpose of Assignment

Using the case study below, prepare a 2-3 page paper. A 21-year old female (A.M.) presents to the urgent care clinic with symptoms of nausea, vomiting, diarrhea, and a fever for 3 days. She states that she has Type I diabetes and has not been managing her blood sugars since she’s been ill and unable to keep any food down. She’s only tolerated sips of water and juices. Since she’s also been unable to eat, she hasn’t taken any insulin as directed. While helping A.M. from the lobby to the examining room you note that she’s unsteady, her skin is warm and flushed, and that she’s drowsy. You also note that she’s breathing rapidly and smell a slight sweet/fruity odor. A.M. has a challenge answering questions but keeps asking for water to drink. You get more information from A.M. and learn the following: She had some readings on her glucometer which were reading ‘high’; she vomits almost every time she takes in fluid; she hasn’t voided for a day but voided a great deal the day before; she’s been sleeping long hours and finally woke up this morning and decided to seek care. Current labs and vital signs:

1. What is the disorder and its pathophysiology that you expect the health care provider to diagnose and treat?

2. Describe the etiology of the disorder A.M. is experiencing.

3. Identify and describe the clinical manifestations of the disorder A.M. is experiencing.

4. Identify and describe the expected treatment options for A.M. based on the disorder and clinical manifestations.

Instructions: Summarize the questions above and formulate what may be happening with A.M. and the expected treatments to improve her condition. Use at least one scholarly source to support your findings. Be sure to cite your sources in-text and on a References page using APA format.

Paper For Above Instructions

Diabetes, particularly Type 1 diabetes (T1D), is characterized by autoimmune destruction of the pancreatic beta cells, leading to an absolute insulin deficiency. In this case study, the 21-year-old female patient, A.M., exhibits classic symptoms of diabetic ketoacidosis (DKA), a severe complication of uncontrolled diabetes. The symptomatology displayed by A.M., including nausea, vomiting, diarrhea, hyperglycemia (elevated glucometer readings), tachycardia, rapid breathing (hyperventilation), and altered consciousness, points towards DKA, which is a life-threatening emergency that requires prompt medical intervention.

1. The disorder expected here is Diabetic Ketoacidosis (DKA), which is often precipitated by illness, infection, or inadequate insulin administration. It occurs when insulin levels are insufficient, resulting in elevated blood glucose levels and the breakdown of fatty acids for energy. This breakdown produces ketone bodies, leading to metabolic acidosis (Manna et al., 2020). Due to her inability to maintain her insulin regimen while ill, A.M. is at risk for severe dehydration, electrolyte imbalances, and ultimately, potential loss of consciousness or even coma without treatment. Therefore, the healthcare provider would likely initiate treatment to restore insulin levels, rehydrate A.M., and correct her electrolyte imbalances.

2. The etiology of DKA can be multifactorial, but A.M.'s case reveals a primary trigger: the interruption of her insulin therapy due to her illness. This interruption may be compounded by her nausea and vomiting, which prevent her from retaining food and fluids, further contributing to dehydration and exacerbating hyperglycemia (Cryer, 2016). Additional contributing factors could include infection, but within this context, it's clear that her uncontrolled diabetes, specifically due to missed insulin doses, is central to the etiology of her current state.

3. Clinical manifestations of DKA include hyperglycemia (blood glucose > 250 mg/dL), acidosis, dehydration, and alterations in mental status. A.M. presents with symptoms of warmth, drowsiness, rapid breathing, and fruity breath odor—the latter being a direct result of elevated ketone production (Umpierrez & Korytkowski, 2016). Her vital signs indicate significant metabolic disturbances, including hypotension (88/46 mmHg) potentially due to dehydration and an increased heart rate (132 bpm), reflecting compensatory mechanisms in response to her critical condition. The absence of urination further clarifies her state of dehydration and renal function impairment.

4. The expected treatment options for A.M. include intravenous (IV) fluid administration to hydrate her and restore electrolyte balance, continuous IV insulin infusion to lower blood glucose and suppress ketogenesis, and monitoring of her electrolytes, particularly potassium, given her lab value of 6.2 mEq/L which indicates hyperkalemia (American Diabetes Association, 2018). Additionally, the underlying cause of her DKA, be it infection or another precipitating factor, should be identified and treated accordingly.

In summary, A.M.’s presentation is indicative of diabetic ketoacidosis, driven largely by her inability to adhere to her insulin regimen during illness. Immediate medical attention through IV fluids and insulin therapy is crucial for stabilization and recovery. Understanding the complexities of pathophysiology in endocrine disorders such as diabetes highlights the importance of consistent management and education for individuals with chronic conditions.
