NUR 155 Exam 2
1. A 75-year-old patient asks the nurse why they seem to have more difficulty controlling their
blood sugar than when they were younger. Which age-related change best explains this?
a) The pituitary gland produces too much GH.
b) Metabolism increases significantly after age 70.
c) Tissues become more resistant to insulin.
d) ADH levels decrease, causing fluid loss.
ANS: c) Tissues become more resistant to insulin.
Explanation: As noted in your study guide, BGL (Blood Glucose Levels) rise with age. This is
primarily due to increased insulin resistance, meaning the body's cells don't respond as
effectively to insulin, and the pancreas may not release insulin as quickly. This leads to higher
blood sugar levels.
2. Which of the following hormones is expected to REMAIN at a consistent level throughout the
aging process?
a) Follicle-stimulating hormone (FSH)
b) Thyroid hormone (T3/T4)
c) Growth hormone (GH)
d) Antidiuretic hormone (ADH)
ANS: b) Thyroid hormone (T3/T4)
Explanation: Your notes specify that while many hormones decrease (GH) or increase (FSH,
LH, ADH), Cortisol, Insulin, and Thyroid hormones typically remain unchanged with age.

3. The nurse is educating a patient scheduled for a thyroid scan. Which patient statement
indicates a need for further teaching?
a) "I will need to collect my urine for 24 hours after the scan."
b) "I must remain very still during the 20-minute procedure."
c) "I should avoid eating shellfish and using iodized salt for several weeks before the test."
d) "I can take my usual multivitamin that contains iodine the day before the test."
ANS: d) "I can take my usual multivitamin that contains iodine the day before the test."
Explanation: A thyroid scan requires the patient to avoid iodine before the test because it takes
about 6 weeks to leave the body. Iodine from a multivitamin would saturate the thyroid and
prevent the uptake of the radioactive tracer, making the scan invalid.
4. A patient's thyroid scan reveals a "cold spot." The nurse understands this finding indicates:
a) An area of the thyroid that is overworking.
b) The presence of Graves' disease.
c) An area of the thyroid that is underactive or non-functioning.
d) A normal finding in an aging thyroid.
ANS: c) An area of the thyroid that is underactive or non-functioning.
Explanation: On a thyroid scan, a "cold spot" means that area did not absorb the radioactive
iodine. This indicates hypoactivity (low function) and raises concern for cysts or cancer. A "hot
spot" indicates hyperactivity.
5. A patient presents with an enlarged neck, difficulty swallowing, and difficulty breathing. The
nurse suspects which condition?
, a) Hyperthyroidism
b) Goiter
c) Thyroid storm
d) Exophthalmos
ANS: b) Goiter
Explanation: A goiter is an enlarged thyroid gland. As it grows, it can press against the
esophagus, causing difficulty swallowing (dysphagia) , and against the trachea, causing
difficulty breathing.
6. The most common cause of hyperthyroidism, which is an autoimmune disorder, is:
a) Excessive doses of levothyroxine
b) A pituitary tumor
c) Iodine deficiency
d) Graves' disease
ANS: d) Graves' disease
Explanation: Your notes clearly state that Graves' disease is the most common type of
hyperthyroidism and that it is an autoimmune disorder.
7. A patient with untreated hyperthyroidism is likely to exhibit which set of symptoms?
a) Weight gain, bradycardia, and cold intolerance
b) Diarrhea, tachycardia, and weight loss
c) Constipation, dry skin, and fatigue
d) Lethargy, hypotension, and hypothermia
