A nurse provides dietary counseling for a patient newly diagnosed
with type 1 diabetes. Which instruction should be included?
- Correct Answer - "You should use a carbohydrate counting
approach to maintain glycemic control." -
Rationale: The goal in type 1 diabetes is to maintain glycemic
control, which counting carbohydrates will accomplish. Eating any
foods that one desires will lead to hyperglycemia. Eating protein
to promote fat breakdown as well as restricting calories may lead
to ketosis and potential ketoacidosis.
What is the most reliable measure for assessing diabetes control
over the preceding three-month period?
Rationale: Self-monitoring and the patient's own reporting allow
for error and subjectivity in reporting diabetes control. Fasting
,blood glucose is a snapshot in time and does not provide detail
about the past three months. Glycosylated hemoglobin (HgbA1c)
provides a reliable assessment of average blood glucose over the
past three months.
Insulin glargine is prescribed for a hospitalized patient who has
diabetes. When will the nurse expect to administer this drug?
- Correct Answer - Once daily at bedtime -
Rationale: Insulin glargine (Lantus) is a peakless long acting (18-
24 hour) insulin that should be administered once daily at
bedtime.
A patient arrives in the emergency department with a heart rate of
128 beats/minute and a temperature of 105°F. The patient's skin
feels hot and moist. The free T4 level is 4 ng/dL. The free T3 level
is 685 pg/dL, and the TSH level is 0.1 microunits/mL. The nurse
caring for this patient will expect to administer ______________.
- Correct Answer - propylthiouracil (PTU) -
Rationale: This patient is experiencing thyrotoxic crisis, or thyroid
storm. PTU is the preferred medication for treatment of thyroid
storm. Methimazole is preferred in reducing hyperthyroidism in
,stable patients. Iodine-131 is used to treat Graves disease by
destroying a portion of the thyroid gland. IV levothyroxine would
not be appropriate since TSH is depressed and both free T4 and
free T3 are elevated.
A nurse obtaining an admission history on an adult patient notes
that the patient has a heart rate of 62 beats per minute, a blood
pressure of 105/62 mm Hg, and a temperature of 96.2°F. The
patient appears pale and complains of always feeling cold and
tired. The nurse will contact the provider to discuss tests for which
condition?
- Correct Answer - Hypothyroidism -
Rationale: The subjective and objective findings suggest possible
hypothyroidism in an adult. Cretinism is congenital hypothyroidism
and diagnosed at a young age. Graves and Plummer disease
cause hyperthyroidism.
The nurse is caring for a pregnant patient recently diagnosed with
hypothyroidism. The patient tells the nurse she does not want to
take medications while she is pregnant. What will the nurse
explain to this patient?
, - Correct Answer - Neuropsychological deficits in the fetus can
occur if the condition is not treated -
Rationale: The fetus does not produce its own thyroid hormone
until week 20 of development and relies on maternal thyroid
hormone production. The thyroid hormone is needed for neural
and physical development.
The nurse prepares a patient with Graves disease for radioactive
iodine (I131) therapy. Which statement made by the patient best
demonstrates understanding of radioactive iodine (I131) therapy?
- Correct Answer - "This drug will be taken up by the thyroid
gland and will destroy the cells to reduce my hyperthyroidism." -
Rationale: I131 therapy for Graves' disease is achieved in one
dose, ranging from 4-10 millicuries. No isolation from family is
required since the drug only affects the thyroid gland, destroying a
portion of the gland to reduce hyperthyroidism. Cold intolerance
and weight gain are related to hypothyroidism.
A nurse caring for a patient, notes that the patient has a
temperature of 40°C (104°F) and a heart rate of 110 beats per
minute. The patient's skin is warm and moist, and the patient
