MULTIPLE CHOICE
| a. | adrenal insufficiency. |
| b. | diabetic ketoacidosis. |
| c. | hyperosmolar, hyperglycemic state. |
| d. | hypoglycemia. |
ANS: B
If the insulin pump fails, the patient with type 1 diabetes will have a complete interruption of insulin delivery; diabetic ketoacidosis will occur. Adrenal insufficiency would not result from insulin pump failure. Hyperosmolar, hyperglycemic state is a hyperglycemic complication associated with type 2 diabetes; this patient has type 1 diabetes. Interruption of insulin delivery in type 1 diabetes would result in hyperglycemia, not hypoglycemia.

MSC: NCLEX Client Needs Category: Physiological Integrity
| a. | An 18-year-old college student with type 1 diabetes who exercises excessively |
| b. | A 45-year-old woman with type 1 diabetes who forgets to take her insulin in the morning |
| c. | A 75-year-old man with type 2 diabetes and coronary artery disease who has recently started on insulin injections |
| d. | An 83-year-old, long-term care resident with type 2 diabetes and advanced Alzheimer’s disease who recently developed influenza |
ANS: D
Hyperosmolar hyperglycemic syndrome is more common in type 2 diabetes; influenza is a stressor that would result in further increases in blood sugar. Some individuals with advanced Alzheimer’s disease cannot communicate thirst needs and may be incontinent, making hypertonic fluid loss more difficult to estimate. Uncontrolled type 1 diabetes is associated with diabetic ketoacidosis. Interruption of insulin delivery related to a missed insulin dose in type 1 diabetes creates a situation of absolute insulin deficiency and is associated with diabetic ketoacidosis. A patient with type 2 diabetes who is new to insulin is at risk for hypoglycemia.
DIF: Cognitive Level: Analyze/Analysis REF: p. 524
OBJ: Describe the pathophysiology and systemic manifestations of disorders resulting from alterations in hormones secreted by the pancreas, adrenal, thyroid, and posterior pituitary glands. TOP: Nursing Process Step: Assessment
MSC: NCLEX Client Needs Category: Physiological Integrity
| a. | Blood glucose >1000 mg/dL |
| b. | Negative ketones in the urine |
| c. | Normal anion gap |
| d. | pH 7.24 |
ANS: D
A pH of 7.24 is indicative of an acidotic state that may accompany diabetic ketoacidosis.
Glucose values of more than 1000 mg/dL are more commonly associated with hyperosmolar hyperglycemic syndrome. Diabetic ketoacidosis is associated with positive urine ketones and an increased anion gap.
DIF: Cognitive Level: Understand/Comprehension
REF: p. 526 | Figure 19-3
OBJ: Describe the methods for assessing the endocrine system, including physical assessment, and interpretation of laboratory and other diagnostic tests.
TOP: Nursing Process Step: Assessment
MSC: NCLEX Client Needs Category: Physiological Integrity
| a. | Activity intolerance |
| b. | Fluid volume deficient |
| c. | Hyperthermia |
| d. | Impaired nutrition, more than body requirements |
ANS: B
Both diabetic ketoacidosis and hyperosmolar hyperglycemic syndrome result in dehydration and hypovolemia; therefore, fluid volume deficit is a priority nursing diagnosis. Even though activity intolerance is a potential nursing diagnosis related to the fatigue associated with metabolic changes in hyperglycemic conditions, it is not a first priority. Hyperthermia is associated with thyroid crisis. Although overweight and obesity are risk factors for type 2 diabetes, during metabolic crisis, the patient has inadequate energy available to tissues because of limited availability and poor utilization of insulin.
