307: Endocrine Disorders
When collecting data on a child diagnosed with diabetes mellitus, the nurse notes that the child has had weight loss and other symptoms of the disease. The nurse would anticipate which finding in the child's fasting glucose levels?
180 mg/dL Explanation: A fasting glucose greater than or equal to 126 mg/dL or higher on two separate occasions is diagnostic for diabetes when other signs such as polyuria and weight loss, despite polyphagia, are present.
The school nurse notes that a child diagnosed with diabetes mellitus is experiencing an insulin reaction and is unable to eat or drink. Which action would be the most appropriate for the school nurse to take?
Administer subcutaneous glucagon. Explanation: If the child having an insulin reaction cannot take a sugar source orally, glucagon should be administered subcutaneously to bring about a prompt increase in the blood glucose level. This treatment prevents the long delay while waiting for a physician to administer IV glucose or for an ambulance to reach the child.
The parents of a child who was diagnosed with diabetes insipidus ask the nurse, "How does this disorder occur?" When responding to the parents, the nurse integrates knowledge that a deficiency of which hormone is involved?
Antidiuretic hormone Explanation: Diabetes insipidus results from a deficiency in the secretion of antidiuretic hormone (ADH). This hormone, also known as vasopressin, is produced in the hypothalamus and stored in the pituitary gland. Hypopituitarism or dwarfism involves a growth hormone deficiency. Diabetes mellitus involves a disruption in insulin secretion. Thyroxine is a thyroid hormone that if deficient leads to hypothyroidism.
A child with a primary growth hormone deficiency is to receive biosynthetic growth hormone. The nurse would explain to the child and parents that this hormone would be given at which frequency? You Selected:
Daily Explanation: Biosynthetic growth hormone, derived from recombinant DNA, is given by subcutaneous injection. The weekly dosage is 0.2 to 0.3 mg/kg, divided into equal doses given daily for best growth.
The nurse is teaching a 12-year-old girl with diabetes mellitus type 2 and her parents about dietary measures to control her glucose levels. Which comment by the child indicates a need for additional teaching?
"I can eat two small cookies with each meal." Explanation: Cookies, cakes, candy, potato chips, and crackers are high in sugars and fats and should be eaten in moderation as special treats; they would not be included with each meal. An apple or orange makes a good snack. Nonfat milk is a better option than whole milk. Long-acting carbohydrates should be the largest category of foods eaten.
A 10-year-old boy has been diagnosed with type 1 diabetes mellitus. He is curious about what the cause of his disease is and asks the nurse to explain it to him. What explanation is best?
"Special cells in a part of your body called the pancreas can't make a chemical called insulin, which helps control the sugar level in your blood." Explanation: When providing instruction to a child, the nurse must consider the developmental age. Type 1 diabetes is a disorder that involves an absolute or relative deficiency of insulin, in contrast to type 2 where insulin production is only reduced. Insulin is produced by beta islet cells in the pancreas. Diabetes insipidus is caused by the pituitary gland not producing enough ADH and is characterized by extreme thirstiness and polyuria. Insufficient growth hormone is also related to dysfunction of the pituitary gland.
The nurse is teaching a 9-year-old girl with diabetes mellitus type 1 and her parents about blood glucose monitoring. Which comment indicates a need for additional teaching?
"The normal level for her is 70 to 110 mg/dL before meals." Explanation: If the parents state that the normal level for their child is 70 to 110 mg/dL, they need to be reminded that the proper level for a 9-year-old child with type 1 diabetes is 80 to 150 mg/dL. The normal blood glucose level for a 7-year-old child with type 1 diabetes is 90 to 180 mg/dL before meals and 100 to 180 mg/dL before bedtime. The child is correct that she will check her glucose before meals; she should also check it before bedtime snacks. The child is also correct that she will check her glucose level more often when she is sick, during prolonged exercise, after a larger-than-normal meal, and if she suspects nighttime hypoglycemia.
The nurse is caring for a 13-year-old girl with delayed puberty. Based on the nurse's knowledge of this condition, the nurse would include which nursing diagnosis in the child's plan of care?
Deficient knowledge related to the administration of estradiol Explanation: Deficient knowledge related to the administration of estradiol is an appropriate nursing diagnosis for this child. There are oral, transdermal, topical, injectable, and vaginal preparations available. Disabled family coping due to the child's disorder and noncompliance due to long-term therapy are not likely diagnoses because of the simplicity and brevity of the treatment for this disorder. Imbalanced nutrition evidenced by short stature would be appropriate for a child with growth hormone deficiency.
The nurse is preparing a teaching plan for the family and their 6-year-old son who has just been diagnosed with diabetes mellitus. What would the nurse identify as the initial goal for the teaching plan?
Developing management and decision-making skills Explanation: Developing basic management and decision-making skills related to the diabetes is the initial goal of the teaching plan for this child and family. The nurse would have provided a basic description of the disorder after it was diagnosed. Development of a detailed monthly meal plan would come later, perhaps after consulting with a nutritionist. It is too soon to expect the boy to administer his own insulin.
After hospital discharge, the mother of a child newly diagnosed with type 1 diabetes mellitus telephones the nurse because her daughter is acting confused and very sleepy. Which emergency measure would the nurse suggest the mother carry out before she brings the child to see her doctor?
Give her a glass of orange juice. Explanation: These are typical symptoms of hypoglycemia. Administering a form of glucose would help relieve them. Insulin cannot be absorbed when taken orally.
The nurse is interviewing the caregivers of a child admitted with a diagnosis of type 1 diabetes mellitus. The caregiver states, "The teacher tells us that our child has to use the restroom many more times a day than other students do." The caregiver's statement indicates the child most likely has:
Polyuria Explanation: Symptoms of type 1 diabetes mellitus include polyuria (dramatic increase in urinary output, probably with enuresis), polydipsia (increased thirst), and polyphagia (increased hunger and food consumption). Pica is eating nonfood substances.
A child with growth hormone deficiency is receiving growth hormone. What result would the nurse interpret as indicating effectiveness of this therapy?
Height increase of 4 inches Explanation: Effectiveness of growth hormone therapy is indicated by at least a 3- to 5-inch increase in linear growth in the first year of treatment. Rapid weight gain and headaches are adverse reactions of this therapy. The drug is stopped when the epiphyseal growth plates close.
The nurse is caring for a 10-year-old boy with growth hormone deficiency. Which therapy would you anticipate will be prescribed for him?
Injections of growth hormone Explanation: Growth hormone deficiency occurs when the pituitary is unable to produce enough hormone for usual growth. Administering subcutaneous growth hormone supplements this.
The nurse is caring for a 3-year-old diagnosed with diabetes mellitus. The child's eating patterns are unpredictable. One day the child will eat almost nothing, the next day the child eats everything on her tray. The nurse recognizes that this type of insulin would most likely be used in treating this child?
Rapid-acting insulin Explanation: The introduction of rapid-acting insulin, such as lispro, has greatly changed insulin administration in children. The onset of action of rapid-acting insulin is less than 15 minutes. Rapid-acting insulin can even be used after a meal in children with unpredictable eating habits. Regular, intermediate, and long-acting insulin all have a longer onset, peak, and duration than rapid acting insulin, and are more difficult to regulate in the child with unpredictable eating patterns.
A child who has type 1 diabetes mellitus is brought to the emergency department and diagnosed with diabetic ketoacidosis. What treatment would the nurse expect to administer?
Regular insulin Explanation: Insulin for diabetic ketoacidosis is given intravenously. Only regular insulin can be administered by this route.
A nurse is providing education to a woman at 28 weeks' gestation who has tested positive for gestational diabetes mellitus (GDM). What would be important for the nurse to include in the client teaching?
She is at increased risk for type 2 diabetes mellitus after her baby is born. Explanation: The woman who develops GDM is at increased risk for developing type 2 diabetes mellitus after pregnancy.
A 14-year-old girl visits her gynecologist and is found to have vaginal candidiasis. She is obese, claims to not be sexually active, and is not on an oral contraceptive. Which intervention should be considered for this client?
Test her urine for glucose to rule out diabetes mellitus Explanation: Candidiasis is a vaginal infection spread by the fungus Candida, an organism which thrives on glycogen. Because oral contraceptives produce a pseudopregnancy state, adolescents using oral contraceptives tend to have frequent vaginal candidal infections. If being treated with an antibiotic for another infection (which destroys normal vaginal flora and lets fungal organisms grow more readily), they are also particularly susceptible to this infection. Thus, neither prescription of an oral contraceptive or prescription of an antibiotic would be appropriate in this case. Incidence is also strongly associated with immune suppression and diabetes mellitus, because hyperglycemia provides the perfect glucose-rich environment for candidal growth. If a girl has frequent candidal infections, her urine should be tested for glucose to rule out diabetes mellitus. Teach women to insert antifungal tablets or creams at bedtime, not in the morning, so the drug does not drain from the vagina immediately afterward.
Which factors are known to contribute to vaginal yeast infections? Select all that apply.
poorly controlled diabetes recent antibiotic therapy use of oral contraceptives High hormone levels during pregnancy Explanation: Reported risk factors for the overgrowth of C. albicans include recent antibiotic therapy, which suppresses the normal protective bacterial flora; high hormone levels owing to pregnancy or the use of oral contraceptives, which cause an increase in vaginal glycogen stores; and uncontrolled diabetes mellitus or HIV infection because they compromise the immune system. Exercise and glandular inflammation are not noted risk factors for yeast infections.
The nursing diagnosis most applicable to a child with growth hormone deficiency would be:
risk for situational low self-esteem related to short stature. Explanation: Children who are short in stature can develop low self-esteem from their altered appearance.
The most common mixture of insulin used with children with type 1 diabetes mellitus is a combination of an intermediate-acting insulin and a regular insulin, usually in a 2:1 ratio or 0.75 units of the intermediate-acting insulin to 0.33 units regular insulin, and given in the same syringe.
True
The nurse is assessing a 13-year-old boy with type 2 diabetes mellitus. What would the nurse correlate with disorder?
The parents report that their son "can't drink enough water." Explanation: Unquenchable thirst (polydipsia) is a common finding associated with diabetes mellitus, type 1 and 2. However, reports of flu-like illness and Kussmaul breathing are more commonly associated with type 1 diabetes. Blood pressure is normal with type 1 diabetes and elevated with type 2 diabetes.
A 15-year-old girl is brought to the clinic by her mother because the girl has been experiencing irregular and sporadic menstrual periods and excessive body hair growth. Polycystic ovary syndrome is suspected. Which additional assessment finding would help to support this suspicion?
Darkened pigmentation around the neck area Explanation: Acanthosis nigricans (darkened, thickened pigmentation, particularly around the neck or in the axillary region) is associated with polycystic ovary syndrome. Serum levels of free testosterone typically are elevated with polycystic ovary syndrome. With polycystic ovary syndrome, body mass index indicates overweight or obesity. Short stature typically is associated with growth hormone deficiency.
The nurse is interviewing the caregivers of a child admitted with a diagnosis of type 1 diabetes mellitus. The caregiver states, "She is hungry all the time and eats everything, but she is losing weight." The caregiver's statement indicates the child most likely has:
Polyphagia Explanation: Symptoms of type 1 diabetes mellitus include polyphagia (increased hunger and food consumption), polyuria (dramatic increase in urinary output, probably with enuresis) and polydipsia (increased thirst). Pica is eating nonfood substances.
A nurse is teaching a child with type 1 diabetes mellitus how to self-inject insulin. Which method should she recommend to the child for regular doses?
Subcutaneously in the outer thigh Explanation: Insulin is always injected SC except in emergencies, when half the required dose may be given IV. SC tissue injection sites used most frequently in children include those of the upper outer arms and the outer aspects of the thighs. The abdominal SC tissue injection sites commonly used in adults can be adequate sites but most children dislike this site as abdominal skin is tender.
The nurse working with the child diagnosed with type 2 diabetes mellitus recognizes that most often the disorder can be managed by:
Taking oral hypoglycemic agents Explanation: If the child presents with diabetic ketoacidosis, initial treatment is insulin administration, but then oral hypoglycemic agents such as metformin are often effective for controlling blood glucose levels. Lifestyle changes such as weight loss and increased exercise are important aspects of treatment for the child.
The nurse is assessing a 5-year-old boy whose mother says he has been vomiting lately, has no appetite and has had an extreme thirst. Labwork for diabetes mellitis is being completed. Which symptom would differentiate between diabetes mellitus type 1 over diabetes mellitus type 2?
The child has lost weight recently. Explanation: Weight loss is unique to diabetes mellitus type 1, whereas weight gain is associated with type 2. Hypertension is consistent with diabetes mellitus type 2. The sweet-smelling breath is common to both type 1 and type 2 diabetes and is a sign of ketoacidosis, a medical emergency, which is frequently how children present on initial evaluation. The rapid, deep Kussmaul breathing is common to both type 1 and type 2 diabetes and is a sign of ketoacidosis, a medical emergency, which is frequently how children present on initial evaluation.
The nurse is caring for a child with type 1 diabetes mellitus. The nurse notes that the child is drowsy, has flushed cheeks and red lips, a fruity smell to the breath, and there has been an increase in the rate and depth of the child's respirations. The nurse recognizes that these symptoms indicate the child has:
diabetic ketoacidosis. Explanation: Diabetic ketoacidosis is characterized by drowsiness, dry skin, flushed cheeks and cherry-red lips, acetone breath with a fruity smell, and Kussmaul breathing (abnormal increase in the depth and rate of the respiratory movements).
The nurse is teaching a child with type 1 diabetes mellitus to administer her own insulin. The child is receiving a combination of short-acting and long-acting insulin. The nurse knows that the child has appropriately learned the technique when she:
draws up the short-acting insulin into the syringe first. Explanation: Drawing up the short-acting insulin first prevents mixing a long-acting form into the vial of short-acting insulin. This maintains the short-acting insulin for an emergency. Insulin is given subcutaneously.
