A patient presents to the physician with complaints of constipation. Which of the following could be the cause? (Select all that apply.)
Neurogenic disorder of the large intestine, Sedentary lifestyle, Low residue diet, Aging, Use of antacids
Constipation can be caused by neurogenic disorders of the large intestine in which neural pathways or neurotransmitters are altered and colon transit time delayed. A low-residue diet (the habitual consumption of highly refined foods) decreases the volume and number of stools and causes constipation. A sedentary lifestyle and lack of regular exercise are other common causes of constipation. Lack of access to toilet facilities and consistent suppression of the urge to empty the bowel are other causes. Excessive use of antacids containing calcium carbonate or aluminum hydroxide often results in constipation. Opiates, particularly codeine, tend to inhibit bowel motility. Conditions associated with constipation include congenital megacolon, hypothyroidism, pelvic hiatal hernia, multiple sclerosis, spinal cord trauma, cancer, cerebrovascular disease, and irritable bowel syndrome-constipation predominant. Aging may result in changes in neuromuscular function, causing constipation.

A 25-year-old male presents with fatigue, constipation, and sexual dysfunction. Tests reveal all pituitary hormones are normal and no masses are present. The nurse suspects the most likely cause of his symptoms is a dysfunction in the:
Correct Answer: Pituitary stalk
Response Feedback: When pituitary hormones are normal, dysfunction in the action of hypothalamic hormones are most commonly related to interruption of the connection between the hypothalamus and pituitary, the pituitary stalk.
A 15-year-old female presents with breast discharge, dysmenorrhea, and excessive excitability. Tests reveal that all her pituitary hormones are elevated. What does the nurse suspect as the most likely cause for these assessment findings?
Correct Answer: A pituitary adenoma
Response Feedback: Hormonal effects of pituitary adenomas include hypersecretion from the adenoma, itself, and hyposecretion from surrounding pituitary cells; in this case prolactin would be elevated with the manifestation of menstrual irregularities and secretion from the breast.
What common neurologic disturbances should the nurse assess for in a patient with a pituitary adenoma?
Correct Answer: Visual disturbances
Response Feedback: The clinical manifestations of pituitary adenomas are visual changes including visual field impairments (often beginning in one eye and progressing to the other) and temporary blindness.

A 19-year-old female with type 1 DM was admitted to the hospital with altered consciousness and the following lab values: serum glucose 500 mg/dl (high) and serum K+ 2 (low). Her parents state that she has been sick with the "flu" for a week. The diagnosis is hyperosmolar hyperglycemia nonketotic syndrome (HHNKS). What relationship do these values have with her insulin deficiency?
Correct Answer: Decreased insulin causes hyperglycemia and osmotic diuresis.
Response Feedback: Because the amount of insulin required to inhibit fat breakdown is less than that needed for effective glucose transport, insulin levels are sufficient to prevent excessive lipolysis and ketosis.
A nurse is reviewing lab results for glycosylated hemoglobin (hemoglobin A1c) levels. A nurse recalls the purpose of this test is to:
Correct Answer: Monitor long-term serum glucose control.
Response Feedback: Glycosylated hemoglobin refers to the permanent attachment of glucose to hemoglobin molecules and reflects the average plasma glucose exposure over the life of a red blood cell (approximately 120 days).
When a patient asks what causes hyperglycemia in type 2 DM, how should the nurse respond? Hyperglycemia is a result of:
Correct Answer: Hyperinsulinemia
Response Feedback: Type 2 diabetes is due to hyperinsulinemia and insulin resistance.
A 19-year-old female with type 1 DM was admitted to the hospital with the following lab values: serum glucose 500 mg/dl (high), urine glucose and ketones 4+ (high), and arterial pH 7.20 (low). Her parents state that she has been sick with the "flu" for a week. Which of the following statements best explains her acidotic state?
Correct Answer: Insulin deficiency promotes lipid metabolism and ketone formation.
Response Feedback: With insulin deficiency, lipolysis is enhanced, and there is an increase in the amount of nonesterified fatty acids delivered to the liver. The consequence is increased glyconeogenesis contributing to hyperglycemia and production of ketone bodies (acetoacetate, hydroxybutyrate, and acetone) by the mitochondria of the liver at a rate that exceeds peripheral use.
A 13-year-old male who uses insulin to control his type 1 diabetes experiences hunger, lightheadedness, tachycardia, pallor, headache, and confusion during gym class. The most probable cause of these symptoms is:
Correct Answer: Hypoglycemia caused by increased exercise
Response Feedback: The boy is experiencing hypoglycemia due to increased glucose utilization with exercise.
A 55-year-old female is admitted to the medical unit for complications of long-term, poorly controlled type 2 DM. Which of the following would the nurse expect to find in addition to elevated glucose?
Correct Answer: Atherosclerosis
Response Feedback: Macrovascular disease (lesions in large and medium sized arteries) increases morbidity and mortality and increases risk for accelerated atherosclerosis.
When a staff member asks the nurse what causes the chronic complications of DM such as microvascular and macrovascular disease, how should the nurse respond? These complications are primarily related to:
Correct Answer: Hyperglycemia
Response Feedback: The underlying cause of the micro and macro diseases associated with diabetes is due to hyperglycemia
A nurse checks lab results as both Cushing syndrome and Addison disease can manifest with elevated levels of:
Correct Answer: Adrenocorticotropic hormone (ACTH)
Response Feedback: Cushing syndrome and Addison are related to elevated levels of ACTH.
A 35-year-old female took corticosteroid therapy for several months. Which of the following would the nurse expect to find?

A 50-year-old female presents with lightheadedness and overall abnormal feelings. Hyperaldosteronism is diagnosed. Which of the following symptoms would the nurse expect?
Correct Answer: Hypokalemia
Response Feedback: Hypokalemia occurs due to increased renal secretion of potassium.
A 49-year-old female is diagnosed with hypercortisolism. Which of the following would the nurse expect?
Correct Answer: Osteoporosis
Response Feedback: The effects of hypercortisolism in bone cause loss of the protein matrix leading to osteoporosis, with pathologic fractures, vertebral compression fractures, bone and back pain, kyphosis, and reduced height
The body's inability to conserve water and sodium when affected by Addison disease is explained by which of the following conditions?
Correct Answer: Aldosterone deficiency
Response Feedback: The symptoms of Addison disease are primarily a result of hypocortisolism and hypoaldosteronism.
