NURS 317 Unit 3 Chapter 37 Pharm Point Questions Flashcards
A client has been admitted with signs and symptoms of hypothyroidism. When planning this client’s care, what nursing diagnosis should the nurse include?
A) Risk for falls related to hypotension
B) Anxiety related to sympathetic nervous stimulation
C) Functional urinary incontinence related to detrusor stimulation
D) Chronic confusion related to central nervous system depression
A) Risk for falls related to hypotension
Rationale:Hypothyroidism is associated with hypotension, which creates a risk for falls. Apathy and depression may occur, but chronic confusion is atypical. Urinary effects are rare, and anxiety is more closely associated with hyperthyroidism.
A positive Chvostek sign suggests hypercalcemia.
A) FALSE
B) TRUE
A) FALSE
Rationale:Hypocalcemia is indicated by a positive Chvostek sign.
Thyroid hormones can be measured as protein-bound iodine.
A) FALSE
B) TRUE
B) TRUE
Rationale:When thyroid hormone is needed in the body, the stored thyroid hormone molecule is absorbed into the thyroid cells, where the T3 and T4 are broken off and released into circulation. These hormones are carried on plasma proteins, which can be measured as protein-bound iodine (PBI) levels.
A client has been diagnosed with low bone density and daily intranasal administration of calcitonin salmon has been prescribed. When reviewing the client’s medication record, the nurse notices that the client also takes a beta-adrenergic blocker and a loop diuretic for the treatment of hypertension. What is the nurse’s best action?
A) Administer each of the client’s medications as prescribed.
B) Contact the care provider to question the use of calcitonin in this client.
C) Ensure that the calcitonin is given at least 30 minutes before the beta-blocker and diuretic.
D) Contact the care provider to determine whether the diuretic should be put on hold.
A) Administer each of the client’s medications as prescribed.
Rationale:There have been no clinically important drug–drug interactions reported with the use of calcitonin. There is no clear reason to question this order, and the drugs do not have to be separated by time.
The nurse is caring for a client newly diagnosed with hypothyroidism who is prescribed levothyroxine. What drug teaching will the nurse provide this client? Select all that apply.
A) “Take the tablet on a full stomach.”
B) “You will need to take this drug every day for the rest of your life.”
C) “Initially you will need to have thyroid levels drawn daily.”
D) “Take the tablet at the same time every day.”
E) “Take the medication with a full glass of water.”
B) “You will need to take this drug every day for the rest of your life.”
D) “Take the tablet at the same time every day.”
Rationale:Adults who require thyroid replacement therapy need to understand that this will be a lifelong replacement need. An established routine of taking the tablet first thing in the morning may help the client to comply with the drug regimen. These drugs should always be taken with a full glass of water to decrease the risk of esophageal atresia. Thyroid levels are generally drawn every few weeks to months initially because introduction of the exogenous hormone causes a period of hormonal adjustment that does not stabilize immediately. The drug should be taken on an empty stomach to promote absorption.E) “Take the medication with a full glass of water.
What would the nurse expect to assess if a client was receiving too much methimazole?
A) Nervousness
B) Decreased appetite
C) Flushed warm skin
D) Tachycardia
B) Decreased appetite
Rationale:Decreased appetite is associated with hypothyroidism, suggesting that the client is receiving too much methimazole, an antithyroid drug. Nervousness, flushed skin, and tachycardia would indicate hyperthyroidism, suggesting that the client is not receiving enough methimazole rather than too much.
Calcitonin balances the effects of parathyroid hormone.
A) FALSE
B) TRUE
B) TRUE
Rationale:The thyroid gland is made up of cells arranged in circular follicles. The center of each follicle is composed of colloid tissue, in which the thyroid hormones produced by the gland are stored. These cells produce the hormone calcitonin, which affects calcium levels and acts to balance the effects of the parathyroid hormone parathormone.
The nurse is assessing a client receiving strong iodide solution. What would alert the nurse to the possible development of iodism? Select all that apply.
A) Salivary gland swelling
B) Sore teeth
C) Throat burning
D) Constipation
E) Metallic taste
B) Sore teeth
C) Throat burning
E) Metallic taste
Rationale:Signs of iodism include a metallic taste, burning mouth and throat, sore teeth and gums, head cold symptoms, stomach upset, and diarrhea. Salivary gland swelling is an adverse effect of strong iodide solution but not an indication of iodism.
The care team is planning the medication regimen for a client with hypothyroidism. What assessment best addresses the possible adverse effects of using liotrix?
A) “Do you have any allergies to shellfish or contrast solution?”
B) “Do you do shift work or have significant disruptions in your sleep cycle.”
C) “Do you have any history of heart disease?”
D) “Are you currently taking any vitamin supplements?”
C) “Do you have any history of heart disease?”
Rationale:Liotrix is contraindicated in clients with heart disease. Client variables related to sleep patterns, vitamins, or allergies would not necessary contraindicate its use.
A client is receiving calcitonin by IM injection. The nurse would expect the drug to exert its peak action within which time frame?
A) 1 to 2 hours
B) 3 to 4 hours
C) ½ to 1 hour
D) 2 to 3 hours
B) 3 to 4 hours
Rationale:Calcitonin by IM injection peaks in 3 to 4 hours.
Graves disease is the most common cause of hyperthyroidism.
A) FALSE
B) TRUE
B) TRUE
Rationale:Graves disease, a poorly understood condition that is thought to be an autoimmune problem, is the most common cause of hyperthyroidism.
An 85-year-old long-term care resident with a diagnosis of osteoarthritis has been taking alendronate for several years. The client’s most recent laboratory testing reveals a serum calcium level of 6.1 mg/dL. What is the nurse’s best action?
A) Administer the alendronate with a calcium supplement.
B) Recognize this finding as evidence of therapeutic effect.
C) Assess the client for signs and symptoms of hypercalcemia.
D) Contact the provider to check whether the alendronate should be withheld.
D) Contact the provider to check whether the alendronate should be withheld.
Rationale:A bisphosphonate could exacerbate the client’s hypocalcemia. The nurse should consequently collaborate with the care provider. Hypocalcemia is a not a desired effect of the drug. Alendronate should not be taken with other supplements, which would not be beneficial.
What does the nurse identify as being stored in the follicular cells of the thyroid? Select all that apply.
A) Calcitonin
B) T4
C) Iodine
D) Parathormone
E) T3
B) T4
E) T3
Rationale:T3 and T4 are produced by the thyroid gland and stored in the follicular cells. The parafollicular cells of the thyroid produce calcitonin. Parathormone is produced by the parathyroid glands. Iodine is supplied by the diet.
The nurse receives an order to administer 15 mcg/kg/day of levothyroxine to a 4-year-old child who weighs 23 kg. How many micrograms of medication will the nurse administer?
_____________ mcg
345mg
Rationale:Calculate the proper dosage by multiplying weight in kilograms by micrograms per kilogram to administer. 15 × 23 = 345 mcg.
The nurse is describing the normal physiology of the thyroid gland to a client. What should the nurse teach the client?
A) “T3 is less common, but more physiologically active, than T4.”
B) “More T3 is released into circulation than T4.”
C) “T3 and T4 are attached to glucose for transport throughout the body.”
D) “Thyroid hormone is released as T3 and then subsequently converted into T4.”
A) “T3 is less common, but more physiologically active, than T4.”
Rationale:T3 is approximately four times more active than T4, though it exists in smaller quantities. Most T4 is converted into T3. T3 and T4 are carried on plasma proteins, not glucose.
