Module 8 Case Study

Question 1

Jeff is a 57-year-old male with a long history of type 1 diabetes. He takes insulin to manage his diabetes, but has been having trouble maintaining steady blood glucose levels over the last two weeks. Jeff suffered a week-long case of influenza last month, but is otherwise healthy. This morning, he began vomiting upon waking. This was followed by extreme abdominal pain and extreme thirst. He called his endocrinologist, who told him that he needs to seek emergency care.

Given Jeff’s history of type 1 diabetes, which of the following conditions is he most likely experiencing?

Question 2

Diabetic ketoacidosis is a type of respiratory acidosis.

Question 3

If Jeff has diabetic ketoacidosis, which of the following symptoms may he also be experiencing?

Question 4

To diagnosis his condition, a blood osmolality test is ordered. An abnormally high result could point to all of the following conditions EXCEPT:

Question 5

If Jeff has an acidic condition related to his diabetes, which of the following signs are likely to be present?

Question 6

Briefly explain why Jeff has a feeling of extreme thirst.

Response Feedback: [None Given]

Question 7

Metabolic acidosis results is low blood pH levels and high bicarbonate ion concentration.

Question 8

If Jeff’s condition goes untreated, his body may begin to hyperventilate to compensate for the change in his blood pH levels.

Question 9

Treatment for Jeff’s acidic condition may include all of the following EXCEPT:

Question 10

Kidney failure, cardiac arrest, and cerebral edema are all possible complications if Jeff’s condition is not treated.

Question 11

Hiro is a 46-year-old male who has recently acquired severe food poisoning, which caused 72 hours of frequent vomiting and diarrhea. The third day after his symptoms began, Hiro experienced heart palpitations and confusion. He had trouble answering simple questions and felt disoriented. His care team was concerned about these new symptoms and decided to perform a urinalysis and several blood tests to determine the cause. These are Hiro’s results:

Blood Calcium Level: 4.6 mEq/L

Blood Sodium Level: 140 mEq/L

Blood Potassium Level: 2.9 mEq/L

Urine Specific Gravity: 1.020

Which of the following conditions is Hiro experiencing?

Question 12

Briefly explain why Hiro’s food poisoning led to an electrolyte imbalance.

Response Feedback: [None Given]

Question 13

In addition to what Hiro has already experienced, which of the following symptoms may be related to Hiro’s condition? (Select all that apply.)

Question 14

In Hiro’s case, how is stomach acid related to the loss of potassium?

Response Feedback: [None Given]

Question 15

How is Hiro’s specific gravity level related to his level of hydration?

Response Feedback: [None Given]

Question 16

Hiro’s electrolyte imbalance is caused by vomiting and diarrhea. Which of the following could also cause his condition? (Select all that apply.)

Question 17

Explain how Hiro’s kidneys will help return his potassium levels to normal.

Response Feedback: [None Given]

Question 18

Most of the body’s potassium is found in the:

Question 19

Why do potassium levels have such a strong effect on muscle function?

Question 20

Which of the following treatments would be most appropriate for Hiro?
