Question 1
Regular
What is the pattern of inheritance for most inborn errors of metabolism?
Correct!
Incorrect
The correct answer is: A
Rationale
Most inborn errors of metabolism follow an autosomal recessive pattern of inheritance. This means that two copies of the mutated gene, one from each parent, are required for the disorder to manifest, making it more prevalent in certain populations.
B: Autosomal dominant In this inheritance pattern, only one mutated copy of the gene is sufficient to cause the disorder, which is not typical for inborn errors of metabolism.
C: X-linked recessive This pattern involves genes located on the X chromosome, affecting primarily males. Inborn errors of metabolism do not predominantly follow this type of inheritance.
D: Multifactorial This pattern involves multiple genes and environmental factors contributing to the disorder, which does not represent the genetic basis of most inborn errors of metabolism.

Question 2
Regular
What occurs as a result of an inadequate secretion of insulin?
Correct!
Incorrect
The correct answer is: B
Rationale
Inadequate secretion of insulin leads to increased fat breakdown, resulting in ketonemia. This occurs because insufficient insulin prevents glucose uptake, forcing the body to utilize fat for energy, producing ketones as byproducts.
A: Protein synthesis is increased. Insulin typically promotes protein synthesis; insufficient insulin would hinder this process, not enhance it, leading to muscle breakdown instead.
C: Serum glucose levels are markedly decreased. Without adequate insulin, glucose levels rise, not fall, as the hormone's primary role is to facilitate glucose uptake into cells.
D: More rapid conversion and storage of carbohydrates to glucose occurs. Insufficient insulin would impair carbohydrate storage and conversion, leading to elevated glucose levels rather than efficient processing.

Question 3
Regular
On what understanding does the nurse plan the care of a child with a new diagnosis of type 1 diabetes mellitus?
Correct!
Incorrect
The correct answer is: A
Rationale
There is an absolute deficiency of insulin. This understanding is crucial for planning care in a child with type 1 diabetes, as it directly informs insulin administration, dietary management, and monitoring strategies necessary to maintain blood glucose levels within a safe range.
B: Insufficient quantities of insulin are produced by the pancreas. This option misrepresents type 1 diabetes, where the pancreas produces little to no insulin due to autoimmune destruction of beta cells.
C: Oral hypoglycemic agents can control it. Oral medications are not effective for type 1 diabetes, as the condition necessitates insulin therapy due to the total lack of endogenous insulin production.
D: Insulin deficiency is caused by another disease affecting the pancreas. This choice incorrectly attributes type 1 diabetes to an external disease process rather than the autoimmune destruction of insulin-producing cells, which is its fundamental cause.

Question 4
Regular
A child receives a combination of regular and NPH insulin at 8:00 AM. At 8:45 AM the breakfast trays have not yet arrived from the kitchen. What is the best action by the nurse?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Give the patient a snack of graham crackers and milk.
Providing a snack is essential to prevent hypoglycemia after administering insulin, especially when breakfast is delayed. This action helps maintain the child's blood glucose levels and ensures safety.
A: Notify the charge nurse.
While communication is important, notifying the charge nurse does not address the immediate need for food, leaving the child vulnerable to low blood sugar levels.
C: Ambulate the patient in the hall for a short time.
Ambulation may increase insulin sensitivity and potentially lower blood glucose levels, which could exacerbate the risk of hypoglycemia when food is not yet available.
D: Give the patient more insulin according to the sliding scale.
Administering additional insulin could lead to an unsafe drop in blood glucose levels, particularly since the child has not yet consumed any food after receiving the initial insulin dose.

Question 5
Regular
Although the child with type 1 diabetes had her prescribed insulin at 7:30 AM, the child is complaining of hunger and thirst and is drowsy at 10:30 AM. What should the nurse do first?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Give her a cup of orange juice. Administering orange juice provides quick carbohydrates to address potential hypoglycemia, which is crucial when a child with type 1 diabetes exhibits signs of hunger and drowsiness.
A: Walk the patient in the hall for 10 minutes. Physical activity may exacerbate symptoms of hypoglycemia, potentially worsening the child’s condition rather than addressing immediate hunger and thirst.
B: Allow the patient a short nap. Sleeping does not resolve the symptoms of hunger and thirst, which may indicate low blood sugar levels needing prompt intervention rather than rest.
D: Test her blood with a glucometer and give insulin according to the sliding scale. Insulin administration without addressing possible hypoglycemia could further endanger the child’s health, making immediate glucose intake more appropriate.

Question 8
Regular
Which general dietary measure should the nurse include in a teaching plan for the child with type 1 diabetes mellitus?
Correct!
Incorrect
The correct answer is: B
Rationale
Focus on complex carbohydrates and eat foods high in fiber. This approach helps stabilize blood sugar levels, allows for better glycemic control, and supports overall nutritional needs essential for children with type 1 diabetes mellitus.
A: Control intake of carbohydrates and consume fewer calories. While carbohydrate management is crucial, merely reducing calorie intake without considering the quality of carbohydrates may not effectively support blood sugar regulation.
C: Obtain most calories from proteins and fats. Prioritizing proteins and fats can lead to inadequate carbohydrate intake, which is vital for energy and proper metabolic function in children with diabetes.
D: Eat a diet low in fat and low in complex carbohydrates. Limiting complex carbohydrates undermines the ability to maintain stable glucose levels, which is essential for effective diabetes management in children.

The nurse discussed treatment of hypoglycemia with an adolescent. Which statement by the adolescent leads the nurse to determine the patient understood the instructions?
Correct!
Incorrect
The correct answer is: A
Rationale
When my blood glucose is low or if I begin to feel hungry and weak, I will eat six LifeSavers. This response indicates a clear understanding of treating hypoglycemia by consuming a quick source of sugar, which is critical for rapidly elevating blood glucose levels and alleviating symptoms associated with low blood sugar.
B: When my blood glucose is low or if I begin to feel hungry and weak, I will give myself Lispro insulin. Administering insulin would exacerbate hypoglycemia rather than alleviate it, as it lowers blood glucose levels instead of raising them.
C: When my blood glucose is low or if I begin to feel hungry and weak, I will have a slice of cheese. Cheese lacks sufficient carbohydrates needed for immediate treatment of hypoglycemia, which requires a fast-acting sugar source to restore glucose levels quickly.
D: When my blood glucose is low or if I begin to feel hungry and weak, I will drink a diet soda. Diet soda contains no sugar, thus failing to provide the necessary glucose to effectively counteract low blood sugar symptoms during hypoglycemic episodes.
