Question

The nurse is assessing a client who has been receiving warfarin for the treatment of a deep vein thrombosis. Which finding indicates that the medication is effective?

Laboratory Test

Normal Findings (Conventional Units)

International Normalized Ratio

Answer 1

Correct Answers:

The client's international normalized ratio is 2.3.

Rationale :

🟩 CORRECT — INR 2.3

🟩 Warfarin effectiveness is measured by the INR, which shows how long it takes blood to clot.

🟩 For treatment of deep vein thrombosis, the target therapeutic INR is 2.0–3.0.

🟩 An INR of 2.3 means the client is in the correct therapeutic range and warfarin is achieving desired anticoagulation.

🟩 This reduces the risk of clot extension or new clot formation, confirming that treatment is effective.

🟩 INCORRECT — New-onset hematuria

🟩 Hematuria indicates bleeding, a sign of warfarin toxicity, not therapeutic effect.

🟩 This finding suggests the INR may be too high, putting the client at risk for hemorrhage.

🟩 The nurse should notify the provider and assess for bleeding risk.

🟩 This does not indicate effective treatment.

🟩 INCORRECT — Calf pain and swelling

🟩 These are symptoms of an active or worsening DVT, meaning warfarin is not effective.

🟩 Continued clot symptoms suggest inadequate anticoagulation or clot progression.

🟩 This finding requires immediate evaluation.

🟩 It does not indicate therapeutic benefit.

🟩 INCORRECT — Elevated D-dimer

🟩 D-dimer is nonspecific and may remain elevated for weeks after a clot.

🟩 It cannot be used to measure warfarin effectiveness.

🟩 An elevated level does not mean the clot is worsening or improving.

🟩 INR is the only appropriate marker for warfarin effectiveness.

Answer 2

Correct Answers:

Up to 50 days

Rationale :

🟦 Amiodarone has an extremely long half-life, reaching up to 50 days, which is unusual compared to most cardiac medications.

🟦 This prolonged half-life occurs because the drug is highly lipid-soluble, causing it to accumulate in tissues and be released slowly over time.

🟦 Due to this extended duration, therapeutic effects and adverse reactions may continue for weeks or even months after the medication is discontinued.

🟦 Nurses must understand this pharmacokinetic property to teach clients about the need for long-term monitoring, including liver, thyroid, and pulmonary assessments.

🟦 Clients may also experience delayed onset of full effects, reinforcing the importance of consistent follow-up care.

❌ Incorrect Options:

30–60 minutes: Too short; does not match the drug’s known prolonged elimination.

24 hours: Still far shorter than amiodarone’s documented half-life.

50 minutes: Pharmacologically impossible for this medication.

Answer 3

Correct Answers:

Rivaroxaban

Rationale :

🟢 Rivaroxaban is an oral anticoagulant that works as a direct factor Xa inhibitor, making it suitable for outpatient management.

🟢 It is absorbed through the gastrointestinal tract, producing predictable anticoagulation without requiring injections.

🟢 This oral administration increases patient convenience and adherence, important for long-term conditions such as DVT, PE, and atrial fibrillation.

🟢 Rivaroxaban also does not require routine lab monitoring, unlike warfarin or injectable anticoagulants.

🟢 Its reliable absorption and predictable action make it a preferred choice for chronic oral anticoagulation therapy.

❌ Incorrect Options:

Alteplase: A thrombolytic given IV only due to rapid breakdown in the GI tract.

Heparin: Must be given IV or subcutaneously, not orally.

Enoxaparin: A subcutaneous injection only, never oral.

Answer 4

Correct Answers:

I should see that my triglycerides are lower, and my HDL levels are higher

Rationale :

🟣 Gemfibrozil belongs to the class of fibric acid derivatives, which primarily act to lower triglyceride levels by reducing hepatic production of VLDL.

🟣 It also helps increase HDL levels, contributing to improved lipid balance and cardiovascular protection.

🟣 This statement shows the client understands the therapeutic goals of the medication, which confirms effective teaching.

🟣 Gemfibrozil is not focused on LDL reduction, so clarifying the correct lipid targets prevents misunderstandings.

🟣 Nurses should reinforce proper timing—taken 30 minutes before meals—to ensure optimal absorption and therapeutic effect.

❌ Incorrect Options:

“Taking this medication with a fatty meal will increase effects”: Fatty meals increase GI side effects, not benefits.

“This medication targets my LDL levels”: Incorrect—gemfibrozil is not primarily for LDL reduction.

“It doesn’t matter how I take this medication”: Wrong—must be taken before meals for best results.

Answer 5

Correct Answers:

Lisinopril 20mg po every day at 0900

Rationale :

💊 Lisinopril is an ACE inhibitor, a drug class known to be teratogenic in pregnancy, especially in the second and third trimesters.

💊 ACE inhibitors can cause fetal renal dysgenesis, oligohydramnios, skull hypoplasia, and neonatal renal failure, which makes them contraindicated once pregnancy is identified.

💊 Because this client now has a positive pregnancy test, the nurse must question the provider about continuing lisinopril and anticipate a safer alternative antihypertensive (such as labetalol or nifedipine).

💊 Recognizing medications that can harm fetal development is a critical aspect of safe medication management in pregnancy and demonstrates appropriate advocacy for maternal–fetal safety.

❌ Azithromycin 250 mg PO daily

💊 Azithromycin is a macrolide antibiotic that is generally considered relatively safe in pregnancy when clearly indicated.

💊 It is often used to treat respiratory, skin, or certain sexually transmitted infections in pregnant clients when benefits outweigh risks.

💊 While all medications in pregnancy should be evaluated carefully, azithromycin does not carry the specific, well-documented teratogenic renal risks associated with ACE inhibitors.

💊 Therefore, this medication would not be the first one the nurse needs to question based solely on a positive pregnancy test.

❌ Ascorbic acid 75 mg PO every day at 0900

💊 Ascorbic acid is vitamin C, and 75 mg is a standard daily supplemental dose that is generally safe in pregnancy.

💊 Vitamin C plays a role in collagen formation, immune function, and tissue repair, all of which are useful during pregnancy.

💊 At this dose, there is no evidence of harm to the fetus, and it may even support maternal nutritional status.

💊 As a result, this prescription would not typically be questioned after a positive pregnancy test.

❌ Acetaminophen 325 mg PO for pain

💊 Acetaminophen is considered the preferred analgesic/antipyretic in pregnancy when used at recommended doses.

💊 It does not carry the same teratogenic or fetal renal toxicity risks as NSAIDs or ACE inhibitors.

💊 Short-term use for pain or fever is generally accepted as safe for both mother and fetus, although prolonged or high-dose use should still be monitored.

💊 Therefore, acetaminophen is not the priority medication to question in response to a new pregnancy finding.

Answer 6

Correct Answers:

Lower LDL

Rationale :

🟢 Low-density lipoprotein (LDL) is often called the “bad cholesterol” because elevated levels are strongly associated with atherosclerosis and cardiovascular disease.

🟢 The primary goal of most lipid-lowering pharmacotherapy (e.g., statins) is to reduce LDL levels to decrease plaque buildup in arteries.

🟢 Lowering LDL helps reduce the risk of myocardial infarction, stroke, and peripheral arterial disease.

🟢 Therefore, the central therapeutic target in high cholesterol treatment is lowering LDL, while also considering other lipid components as secondary goals.

❌ Lower HDL

🔴 High-density lipoprotein (HDL) is known as “good cholesterol” because it helps transport cholesterol away from arteries to the liver for excretion.

🔴 A higher HDL level is protective, lowering the risk of cardiovascular events.

🔴 Lowering HDL would increase risk, which is the opposite of the treatment goal.

🔴 Therefore, this option does not align with the desired outcome of therapy.

❌ Increase fatty acid stores

🔴 Increasing fatty acid stores would indicate more lipid accumulation, which can worsen metabolic and cardiovascular risks.

🔴 Pharmacologic therapy aims to reduce harmful lipids, not store more of them.

🔴 This is not an evidence-based goal of cholesterol treatment.

🔴 Thus, it conflicts with the primary purpose of dyslipidemia management.

❌ Increase triglycerides

🔴 Elevated triglycerides are associated with pancreatitis and cardiovascular disease.

🔴 Many medications (like fibrates and some statins) specifically aim to lower triglycerides, not increase them.

🔴 Raising triglycerides would worsen the client’s lipid profile and risk.

🔴 Therefore, this is not an appropriate treatment goal.

Answer 7

Correct Answers:

Monitor serum potassium

Rationale :

🟣 Furosemide is a loop diuretic that promotes excretion of sodium, water, and potassium in the loop of Henle.

🟣 A major risk is hypokalemia, which can lead to cardiac arrhythmias, muscle weakness, and ECG changes.

🟣 Because of this, monitoring serum potassium levels is a critical safety measure, especially in clients on cardiac medications such as digoxin.

🟣 Identifying and correcting low potassium early helps prevent life-threatening complications related to electrolyte imbalance.

❌ Monitor blood glucose

🟠 While some diuretics can have mild effects on glucose tolerance, this is not the primary or most immediate concern with furosemide.

🟠 Blood glucose monitoring is more crucial with medications like corticosteroids or some antipsychotics.

🟠 It may be appropriate in diabetic clients but is not the key priority related to furosemide’s main adverse effect.

🟠 Therefore, it is secondary to serum potassium monitoring.

❌ High protein diet

🟠 A high-protein diet is not directly required for clients taking furosemide.

🟠 Nutritional needs depend on the client’s overall condition, such as renal or hepatic status.

🟠 Furosemide’s primary concerns relate to fluid and electrolyte balance, not protein intake.

🟠 Thus, this is not the most important nursing action specific to this medication.

❌ Restrict fluid intake

🟠 Furosemide is prescribed to promote diuresis in conditions like heart failure or edema, but routine strict fluid restriction is not automatically indicated.

🟠 Fluid restriction decisions depend on the provider’s orders and the client’s volume status and lab results.

🟠 Inappropriately restricting fluids can cause dehydration and further electrolyte disturbances.

🟠 Therefore, it is not the primary standard action tied to furosemide use.

Answer 8

Correct Answers:

Increased risk of liver damage

Rationale :

💛 Statins (HMG-CoA reductase inhibitors) can cause hepatotoxicity, making liver damage a key safety concern.

💛 Clients on statins require baseline and periodic liver function tests (LFTs) to monitor for elevations in AST and ALT.

💛 Symptoms such as fatigue, right upper quadrant pain, or dark urine may signal liver injury and must be reported promptly.

💛 Recognizing the increased risk of liver damage guides the nurse to provide proper teaching and monitor lab values closely.

❌ Increased risk of gastrointestinal bleeding

🟡 Statins can cause GI upset (e.g., nausea, dyspepsia) but are not primarily associated with GI bleeding.

🟡 GI bleeding risk is more commonly linked to medications like NSAIDs or anticoagulants.

🟡 While any new GI symptom deserves assessment, it is not the classic “alert” specific to statins.

🟡 Thus, this is not the best answer.

❌ Decreased monitoring of labs

🟡 The opposite is true—statins require ongoing lab monitoring, especially LFTs and sometimes lipid panels.

🟡 Decreasing lab monitoring could cause missed detection of hepatotoxicity or myopathy.

🟡 Safe administration involves increased vigilance, not relaxation of monitoring.

🟡 Therefore, this option contradicts good practice.

❌ Decreased risk of muscle pain

🟡 Statins carry a risk of myalgia, myopathy, and rarely rhabdomyolysis, so they do not decrease the risk of muscle pain.

🟡 Clients must be taught to report unexplained muscle pain, tenderness, or weakness.

🟡 Muscle-related side effects are a key reason some clients discontinue statin therapy.

🟡 Hence, this statement is inaccurate as a safety alert.

Answer 9

Correct Answers:

Administer the medication at a slow rate to prevent hearing loss.

Rationale :

💙 Furosemide given IV too rapidly can cause ototoxicity, leading to tinnitus or hearing loss.

💙 To reduce this risk, the medication must be administered slowly, typically not exceeding recommended rates (e.g., 20 mg/min depending on protocol).

💙 This precaution is especially important in clients receiving high doses or with renal impairment.

💙 Slow administration protects the cochlear hair cells and supports safe IV diuretic therapy.

❌ Perform a hearing screen before and after

🔵 While assessing for hearing changes is reasonable, formal pre- and post-hearing screens are not standard for routine IV doses.

🔵 The key safety step is controlling the infusion rate, not mandatory audiologic testing.

🔵 Nurses should monitor for subjective complaints of ringing or hearing changes but do not typically schedule structured hearing screens around each dose.

🔵 Therefore, this is not the primary recommended precaution.

❌ Monitor blood glucose closely

🔵 Furosemide is not primarily known for causing significant acute changes in blood glucose during IV administration.

🔵 Glucose concerns are more clinically relevant for medications like insulin, steroids, or some antipsychotics.

🔵 While overall metabolic status should be considered, it is not the main safety focus when giving IV furosemide.

🔵 Thus, this is not the best answer.

❌ Increase the dosage with other ototoxic drugs

🔵 Combining furosemide with other ototoxic medications (e.g., aminoglycosides) can increase the risk of hearing damage.

🔵 In such cases, providers usually avoid high doses or adjust therapy rather than increase it.

🔵 Increasing the dose would likely worsen ototoxic risk, contradicting safe practice.

🔵 Therefore, this option is incorrect and unsafe.
