A nurse is caring for a patient with a goiter and possible hyperthyroidism. Which action by the nurse has the potential for patient harm? a. The nurse checks the blood pressure in both arms. b. The nurse palpates the neck to assess thyroid size. c. The nurse orders saline eye drops to lubricate the patient's bulging eyes. d. The nurse lowers the thermostat to decrease the temperature in the room.

b. The nurse palpates the neck to assess thyroid size.

The nurse is caring for a patient during a water deprivation test. Which finding is most important for the nurse to communicate to the health care provider? a. The patient reports intense thirst. b. The patient has a 5-lb (2.3-kg) weight loss. c. The patient feels dizzy when sitting on the bed. d. The patient's urine osmolality does not increase.

b. The patient has a 5-lb (2.3-kg) weight loss.

Which additional information would the nurse consider when reviewing the laboratory results for a patient's total calcium level? a. The blood glucose b. The serum albumin c. The phosphate level d. The magnesium level

b. The serum albumin

A patient is scheduled in the outpatient clinic for blood cortisol testing. Which instruction would the nurse provide? a. "Avoid adding any salt to your foods for 24 hours before the test." b. "You will need to lie down for 30 minutes before the blood is drawn." c. "Come to the laboratory to have the blood drawn early in the morning." d.

"I get up several times at night to urinate." c. "I feel a lump in my throat when I swallow." d. "I notice my breasts are always tender lately."

c. "I feel a lump in my throat when I swallow."

In preparation for which test would the nurse teach the patient to minimize physical and emotional stress? a. A water deprivation test b. A test for serum T3 and T4 levels c. A 24-hour urine test for free cortisol d. A radioactive iodine (I-131) uptake test

A patient is taking a drug that blocks the action of aldosterone. Which additional effect of the medication would the nurse monitor? a. Increased serum sodium b. Decreased urinary output c. Elevated serum potassium d. Evidence of fluid overload

c. Elevated serum potassium >Because aldosterone increases the excretion of potassium, a medication that blocks aldosterone will tend to cause hyperkalemia. Aldosterone also promotes the reabsorption of sodium and water in the renal tubules, so spironolactone will tend to cause increased urine output, a decreased or normal serum sodium level, and signs of dehydration

c. Ionized calcium

Which laboratory value would the nurse review to determine whether a patient's hypothyroidism is caused by a problem with the anterior pituitary gland? a. Thyroxine (T4) level b. Triiodothyronine (T3) level c. Thyroid-stimulating hormone (TSH) level d. Thyrotropin-releasing hormone (TRH) level

c. Thyroid-stimulating hormone (TSH) level

An 18-yr-old male patient with small stature is scheduled for a growth hormone stimulation test. Which item would the nurse obtain in preparation for the test? a. Ice in a basin b. Glargine insulin c. A cardiac monitor d. 50% dextrose solution
