1) A nurse is assessing a client who is taking levothyroxine. The nurse should recognize that which of the following
findings is a manifestation of levothyroxine overdose?
a) Insomnia
i) Rationale: Levothyroxine overdose will result in manifestations of hyperthyroidism, which include
Insomnia, tachycardia, and hyperthermia.
b) Constipation
i) Rationale: Constipation is a manifestation of hypothyroidism and indicates an inadequate dose of
levothyroxine.
c) Drowsiness
i) Rationale: Drowsiness is a manifestation of hypothyroidism and indicates an inadequate dose of
levothyroxine.
d) Hypoactive deep-tendon reflexes
i) Rationale: Hypoactive deep-tendon reflexes are manifestations of hypothyroidism and indicate an
inadequate dose of levothyroxine.
2) A nurse is reviewing the medical record of a client who has been on levothyroxine for several months. Which of the
following findings indicates a therapeutic response to the medication?
a) Decrease in level of thyroxine (T4)
i) Rationale: If the dose of this medication has been adequate, the nurse should see an increase in the T4.
b) Increase in weight
i) Rationale: If the dose of this medication has been adequate, the nurse should see a decrease in weight, as
hypothyroidism causes a decrease in metabolism with weight gain.
c) Increase in hr of sleep per night
i) Rationale: If the dose of this medication has been adequate, the nurse should see a decrease in the hr of
sleep per night, as hypothyroidism causes sluggishness with increased hr of sleep.
d) Decrease in level of thyroid stimulating hormone (TSH).
i) Rationale: In hypothyroidism, the nonfunctioning thyroid gland is unable to respond to the TSH, and no
endogenous thyroid hormones are released. This results in an elevation of the TSH level as the anterior
pituitary continues to release the TSH to stimulate the thyroid gland. Administration of exogenous thyroid
hormones, such as levothyroxine, turns off this feedback loop, which results in a decreased level of TSH.
3) A nurse is reviewing the medication list for a client who has a new diagnosis of type 2 diabetes mellitus. The nurse
should recognize which of the following medications can cause glucose intolerance?

i) Rationale: This test is used to monitor warfarin therapy. For a client receiving full anticoagulant
therapy,should typically be approximately two to three times the normal value, depending on the
indication for therapeutic anticoagulation.

hepatic encephalopathy or coma.

K intake but rather should maintain a consistent intake of vitamin K in order to control the
therapeutic effect of the medication.
