Question

The nurse is preparing to administer levothyroxine to a client. Which laboratory value should the nurse assess before administering the medication?

Answer 1

Correct Answers:

Thyroid-stimulating hormone

Rationale :

🔷 TSH is the primary lab used to evaluate thyroid function and guide levothyroxine dosing in most clients.

🔷 Checking TSH trends helps determine whether the client is under-replaced or over-replaced, improving safe administration decisions.

🔷 Levothyroxine has a narrow therapeutic window, so lab monitoring reduces the risk of iatrogenic hyperthyroidism.

🔷 TSH also helps confirm whether the therapy is achieving the goal of stable euthyroid status.

🔷 In routine hypothyroidism care, TSH is the most sensitive and practical indicator to assess before continuing therapy.

Serum calcium level

🔷 Calcium is not the routine lab used to guide levothyroxine therapy.

🔷 Calcium monitoring is more relevant to parathyroid disorders and certain vitamin D therapies.

Calcitriol

🔷 Calcitriol relates to vitamin D metabolism and is not used to evaluate thyroid replacement dosing.

🔷 It does not indicate the client’s thyroid hormone balance.

Alanine aminotransferase (ALT)

🔷 ALT reflects liver function, not thyroid hormone replacement adequacy.

🔷 It is not the standard lab for levothyroxine safety/response monitoring.

Answer 2

Correct Answers:

To treat vitamin B12 deficiency

Rationale :

💎 Cyanocobalamin is vitamin B12, used to treat B12 deficiency and prevent complications like megaloblastic anemia.

💎 Adequate B12 is essential for DNA synthesis, so deficiency leads to abnormal RBC formation and anemia.

💎 It also supports neurologic function, helping prevent or improve paresthesias, gait changes, and cognitive symptoms.

💎 Treatment can be oral or injectable depending on absorption issues (e.g., pernicious anemia).

💎 Correcting B12 deficiency restores normal hematologic production and protects the nervous system.

To reduce inflammation in autoimmune disorders

💎 Cyanocobalamin is not an anti-inflammatory medication and does not treat autoimmune inflammation directly.

💎 It targets nutritional/absorption-related deficiency, not immune suppression.

To treat iron-deficiency anemia

💎 Iron-deficiency anemia requires iron replacement, not vitamin B12.

💎 B12 corrects macrocytic/megaloblastic anemia, not microcytic iron deficiency.

To improve calcium absorption

💎 Calcium absorption is primarily supported by vitamin D, not vitamin B12.

💎 Cyanocobalamin does not increase intestinal calcium uptake.

Answer 3

Correct Answers:

Administer filgrastim subcutaneously at least 24 hours after chemotherapy.

Rationale :

🌟 Filgrastim (G-CSF) stimulates the bone marrow to produce neutrophils, reducing neutropenia risk.

🌟 It must be given at least 24 hours after chemotherapy to avoid stimulating rapidly dividing marrow cells while chemo is still cytotoxic.

🌟 Timing decreases the risk of worsened myelosuppression and supports effective neutrophil recovery.

🌟 The typical route is subcutaneous, and safe administration relies on correct timing and handling.

🌟 Proper scheduling helps prevent severe infection complications such as febrile neutropenia.

Shake the filgrastim vial gently to mix the solution before drawing it up.

🌟 Filgrastim should not be shaken, because shaking can denature proteins and reduce effectiveness.

🌟 Safe handling requires gentle swirling if needed, not agitation.

Administer filgrastim intravenously immediately before chemotherapy.

🌟 Giving it before chemo increases exposure of stimulated marrow cells to cytotoxic therapy.

🌟 This timing can worsen bone marrow suppression and is not safe practice.

Store filgrastim in the freezer and thaw it just before administration.

🌟 Filgrastim is stored refrigerated, not frozen, because freezing can damage the medication.

🌟 Incorrect storage increases risk of reduced potency and unsafe administration.

Answer 4

Correct Answers:

"You should be taking your levothyroxine on an empty stomach in the morning."

Rationale :

🔶 Levothyroxine absorption is best when taken on an empty stomach, usually 30–60 minutes before breakfast.

🔶 Food and certain supplements (especially calcium and iron) can decrease absorption, leading to poor symptom control.

🔶 Consistent timing improves stable hormone levels and more reliable TSH control.

🔶 Teaching the correct administration reduces the risk of undertreatment and fluctuating thyroid levels.

🔶 Morning empty-stomach dosing is the standard routine recommendation for safe, effective therapy.

“You should begin to feel relief of your symptoms within two days of starting the medication.”

🔶 Symptom relief often takes weeks, because thyroid hormone effects build gradually.

🔶 Promising rapid relief can create unsafe expectations and poor adherence.

“If you feel better after a few weeks, you can stop taking the medication”

🔶 Levothyroxine is typically long-term/lifelong in hypothyroidism.

🔶 Stopping abruptly can cause return of hypothyroid symptoms and abnormal labs.

“You should take the levothyroxine at bedtime with a small snack to prevent nausea.”

🔶 Taking it with food can reduce absorption and weaken the medication’s effect.

🔶 If bedtime dosing is used, it should still be empty stomach, not with a snack.

Answer 6

Correct Answers:

"Take glipizide at the same time each day to maintain consistent blood sugar control."

Rationale :

🟢 Glipizide is a sulfonylurea that increases insulin release and works best with consistent daily timing.

🟢 Taking it routinely helps prevent large swings in blood glucose and supports predictable glycemic control.

🟢 Consistency reduces missed doses and improves safe medication habits, lowering the risk of hypoglycemia episodes.

🟢 Safe administration also includes taking it as prescribed with attention to meals to prevent low blood sugar.

🟢 Emphasizing routine timing is a practical way to prevent medication errors and improve adherence.

“Take glipizide with a large glass of water to help with absorption”

🟢 Water does not meaningfully “boost absorption” in a way that prevents errors.

🟢 The bigger safety issue is timing with meals and avoiding hypoglycemia, not water volume.

“If you forget a dose, take two doses at once to make up for the missed one.”

🟢 Double dosing raises the risk of severe hypoglycemia, which can be life-threatening.

🟢 Missed-dose instructions should focus on safe timing, not dose stacking.

“You can safely take glipizide with any other diabetic medication without concern.”

🟢 Combining diabetes medications can increase hypoglycemia risk and requires provider guidance.

🟢 Medication interactions and overlapping effects must be evaluated for safety.

Answer 7

Correct Answers:

Assess the client's thyroid function tests and report the findings to the healthcare provider.

Rationale :

🔴 Palpitations, heat intolerance, and sweating suggest possible excess thyroid hormone (over-replacement).

🔴 The safest nursing action is to assess objective data like TSH and free T4 to evaluate therapy effectiveness and safety.

🔴 Reporting findings supports timely dose adjustment to prevent complications such as dysrhythmias and bone loss.

🔴 Clients should not independently change therapy; levothyroxine dosing must be guided by labs and provider evaluation.

🔴 Prompt assessment and communication protect the client from worsening symptoms of thyrotoxicosis.

Instruct the client to reduce the dose of levothyroxine on her own.

🔴 Dose changes require provider direction and lab correlation to avoid unstable thyroid levels.

🔴 Self-adjustment increases risk of undertreatment or continued over-replacement.

Recommend that the client stop taking the medication immediately and seek emergency care.

🔴 These symptoms warrant evaluation, but immediate stopping and ED care is not always indicated without signs of severe instability.

🔴 The appropriate step is lab assessment and provider notification unless there are emergency red flags.

Reassure the client that these symptoms are a normal side effect and will resolve with time.

🔴 These symptoms are not expected to simply resolve if the dose is too high.

🔴 Reassurance without evaluation can delay care and increase complication risk.

Answer 8

Correct Answers:

Low-grade fever 100.5°F

Rationale :

🟣 A fever can indicate infection, which is high risk because chronic steroids can mask symptoms while suppressing immune response.

🟣 Clients with Addison disease often need stress-dose steroids during illness to prevent adrenal crisis.

🟣 Even a low-grade fever may signal a physiologic stressor requiring prompt provider evaluation and dose adjustment.

🟣 Untreated infection or inadequate steroid coverage can lead to hypotension, shock, and severe electrolyte imbalance.

🟣 Reporting fever early supports timely intervention to maintain hemodynamic stability and prevent crisis.

Weight gain of 6 pounds in 4 months

🟣 Mild weight gain can occur with steroids and is usually monitored over time unless severe or rapid.

🟣 This finding is typically less urgent than signs of infection or crisis risk.

Mild increase in fasting glucose

🟣 Steroids can raise glucose, and mild elevation is commonly monitored and managed with diet/med adjustments.

🟣 It is not as immediately concerning as fever in an adrenal-insufficient client.

Blood pressure 132/88 mmHg

🟣 This BP is mildly elevated and may reflect baseline trends rather than acute danger.

🟣 Addison-related emergencies are more associated with hypotension, especially during illness or missed steroids.

Answer 9

Correct Answers:

You should monitor for signs of dehydration and dry mouth
You may experience weight loss and increased urination, but these effects are expected

Rationale :

You should monitor for signs of dehydration and dry mouth

🔹 Dapagliflozin (an SGLT2 inhibitor) increases glucose excretion in urine, which also pulls water with it (osmotic diuresis).

🔹 This raises the risk for dehydration, especially in older adults or those on diuretics.

🔹 Early dehydration signs include dry mouth, dizziness, thirst, dark urine, and reduced urine output.

🔹 Teaching hydration and symptom monitoring reduces risk of hypotension and acute kidney injury.

🔹 Monitoring for dehydration is a key safety point because fluid loss can happen even when glucose improves.

You may experience weight loss and increased urination, but these effects are expected

🔹 SGLT2 inhibitors can cause mild weight loss due to loss of glucose calories in urine.

🔹 Increased urination is expected because of osmotic diuresis from glucose in the filtrate.

🔹 Clients should be taught to expect this and to maintain adequate fluids unless restricted.

🔹 Understanding expected effects improves adherence and decreases unnecessary discontinuation.

🔹 This teaching supports safe use while the nurse also screens for concerning symptoms (e.g., dehydration).

Dapagliflozin is not recommended for people with history of light prese

🔹 This statement is unclear/incomplete and is not a standard patient-teaching rule as written.

🔹 Dapagliflozin is mainly avoided/cautioned in significant renal impairment and situations that raise dehydration/ketoacidosis risk.

If you experience dizziness or nausea, stop the medication immediately

🔹 Dizziness or nausea should be reported, but stopping immediately without guidance can cause uncontrolled glucose.

🔹 The safer teaching is to assess hydration, check glucose/ketones if indicated, and contact the provider for direction.

Answer 10

Correct Answers:

Weight gain

Rationale :

💎 Hyperthyroidism increases metabolic rate and commonly causes weight loss, heat intolerance, and tachycardia.

💎 Methimazole reduces thyroid hormone production, so improvement toward euthyroid status often includes stabilizing weight and sometimes weight gain.

💎 Weight gain reflects reduced hypermetabolic state and improved nutrient utilization.

💎 It is a clinical sign that thyroid activity is moving toward normal levels, especially if other symptoms also improve.

💎 The nurse should still confirm normalization with TSH and free T4 trends, but weight gain is a supportive assessment cue.

Tachycardia

💎 Tachycardia is a classic sign of continued hyperthyroidism or thyroid storm risk.

💎 Normalization should show a decrease in heart rate, not persistent tachycardia.

Insomnia

💎 Insomnia reflects ongoing sympathetic stimulation seen in hyperthyroidism.

💎 With improvement, sleep patterns typically stabilize, not worsen.

Increased anxiety

💎 Anxiety is linked to excess thyroid hormone increasing adrenergic activity.

💎 Returning to euthyroid status should reduce anxiety rather than increase it.
