A nurse is assessing a client who is taking levothyroxine. The nurse should recognize that
which of the following findings is a manifestation of
... [Show More] 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?
a) Ranitidine
i) Serum creatinine levels
b) Guafenesin
i) Drowsiness and dizziness
c) Prednisone
i) Glucose intolerance and hyperglycemia, patient might require increased
dosage of hypoglycemic med.
d) Atorvastatin
i) Thyroid function tests.
4) A nurse is caring for a client receiving mydriatic eye drops. Which of the following clinical
manifestations indicates to the nurse that the client has developed a systemic
anticholinergic effect?
a) Seizures
b) Tachypnea
c) Constipation
i) Mydriatic eye drops can cause systemic anticholinergic effects such as
constipation, dry mouth, photophobia, and tachycardia.
d) Hypothermia
5) A nurse is caring for a client who has heart failure and is receiving IV furosemide. The
nurse should monitor the client for which of the following electrolyte imbalances?
a) Hypernatremia
i) Rationale: The nurse should monitor the client who is receiving IV furosemide for
hyponatremia.
b) Hyperuricemia
i) Rationale: The nurse should monitor the client who is receiving IV furosemide for
hyperuricemia. The nurse should instruct the client to notify the provider for any
tenderness or swelling of the joints.
c) Hypercalcemia
i) Rationale: The nurse should monitor the client who is receiving IV furosemide for
hypocalcemia.
d) Hyperchloremia
i) Rationale: The nurse should monitor the client who is receiving IV furosemide for
hypochloremia.
6) A nurse is talking to a client who is taking a calcium supplement for osteoporosis. The
client tells the nurse she is experiencing flank pain. Which of the following adverse effects
should the nurse suspect?
a) Renal stones
7) A nurse is caring for a client who is prescribed warfarin therapy for an artificial heart valve.
Which of the following laboratory values should the nurse monitor for a therapeutic effect
of warfarin?
a) Hemoglobin
b) Prothrombin time (PT)
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.
c) Bleeding time
d) Activated partial thromboplastin time (aPTT)
8) A nurse is preparing to administer a dose of lactulose to a client who has cirrhosis. The
client states, "I don't need this medication. I am not constipated." The nurse should explain
that in clients who have cirrhosis, lactulose is used to decrease levels of which of the
following components in the bloodstream?
a) Glucose
b) Ammonia
i) Rationale: Lactulose, a disaccharide, is a sugar that works as an osmotic
diuretic. It prevents absorption of ammonia in the colon. Accumulation
of ammonia in the bloodstream, which occurs in pathologic conditions of
the liver, such as cirrhosis, may affect the central nervous system,
causing hepatic encephalopathy or coma.
c) Potassium
d) Bicarbonate
9) A nurse is educating a group of clients about the contraindications of warfarin therapy.
Which of the following statements should the nurse include in the teaching?
a) "Clients who have glaucoma should not take warfarin."
b) "Clients who have rheumatoid arthritis should not take warfarin."
c) "Clients who are pregnant should not take warfarin."
i) Rationale: Warfarin therapy is contraindicated in the pregnant client
because it crosses the placenta and places the fetus at risk for bleeding.
d) "Clients who have hyperthyroidism should not take warfarin."
10) A nurse is teaching a client who takes warfarin daily. Which of the following statements
by the client indicates a need for further teaching?
a) "I have started taking ginger root to treat my joint stiffness."

b) "I take this medication at the same time each day."
i) Rationale: The client should take warfarin at the same time each day to maintain a
stable blood level.
c) "I eat a green salad every night with dinner."
i) Rationale: Green leafy vegetables are a good source of vitamin K, which can
interfere with the clotting effects of warfarin. Clients who are taking warfarin do not
need to restrict dietary vitamin K intake but rather should maintain a consistent
intake of vitamin K in order to control the therapeutic effect of the medication.
d) "I had my INR checked three weeks ago.
i) " Rationale: Clients who have been taking warfarin for more than 3 months should
have their INR level checked every 2 to 4 weeks.
11)A patient is starting warfarin (Coumadin) therapy as part of treatment for atrial fibrillation.
The nurse will follow which principles of warfarin therapy? (Select all that apply.)
a) Teach proper subcutaneous administration
b) Administer the oral dose at the same time every day
c) Assess carefully for excessive bruising or unusual bleeding
d)Monitor laboratory results for a target INR of 2 to 3
e) Monitor laboratory results for a therapeutic aPTT value of 1.5 to 2.5 times the control
value
12) Atorvastatin can elevate LFT
a) Baseline total cholesterol, LDL and HDL level, triglycerides, and liver and renal function
test obtained and then monitored periodically throughout treatment
