MULTIPLE CHOICE

 

1. A client presents with elevations in triiodothyronine (T₃) and thyroxine (T₄) and with normal thyroid-stimulating hormone (TSH) levels. Which is the nurse’s priority intervention?

a.	Administer levothyroxine (Synthroid).
b.	Administer propranolol (Inderal).
c.	Monitor the apical pulse.
d.	Assess for Trousseau’s sign.

 

 

ANS:  C

The client’s laboratory findings suggest that the client is experiencing hyperthyroidism. The increased metabolic rate can cause an increase in the client’s heart rate, and the client should be monitored for the development of dysrhythmias. Placing the client on a telemetry monitor might also be a precaution. Synthroid is given for hypothyroidism. Propranolol is a beta blocker often used to lower sympathetic nervous system activity in hyperthyroidism. Trousseau’s sign is a test for hypocalcemia.

2. Which is the best instruction for the nurse to give a client scheduled for a thyroid scan?

a.	“You will have external beam radiation.”
b.	“No radiation is used for this scan.”
c.	“No special radiation precautions are needed.”
d.	“Your thyroid will be radioactive for weeks.”

 

 

ANS:  C

The radioactive iodine used in thyroid scans is of low intensity and has such a short half-life that the client is not considered to be a radiation hazard. Thus, no radiation precautions are necessary. The other statements are inaccurate.

3. Which dietary modification does the nurse provide for a client with hyperthyroidism?

a.	Decreased calories and proteins and increased carbohydrates
b.	Elimination of carbohydrates and increased proteins and fats
c.	Increased calories, proteins, and carbohydrates
d.	Supplemental vitamins and reduction of calories

 

 

ANS:  C

The client is hypermetabolic and has an increased need for calories, carbohydrates, and proteins. Proteins are especially important because the client is at risk for a negative nitrogen balance. The other modifications are inappropriate for a client with hyperthyroidism.

4. A client with hyperthyroidism is taking lithium carbonate. Which finding indicates that the client is having side effects of this therapy?

a.	Blurred vision
b.	Increased thirst and urination
c.	Increased sweating and diarrhea
d.	Decreased attention span and insomnia

 

 

ANS:  B

Lithium antagonizes antidiuretic hormone and can cause symptoms of diabetes insipidus. The other choices are not specific to lithium.

5. A client scheduled for a partial thyroidectomy asks the nurse why she is being given an iodine preparation before surgery. Which is the nurse’s best response?

a.	“Iodine will help make the internal surgical environment sterile.”
b.	“It is given to stimulate the storage of excess thyroid hormones.”
c.	“This will replace the hormones you will lose after your operation.”
d.	“It will prevent excessive bleeding during surgery.”

 

 

ANS:  D

Iodine preparations decrease the size and vascularity of the thyroid gland, reducing the risk for hemorrhage and the potential for thyroid storm during surgery. The other answers are not accurate.
