Question

A patient diagnosed with breast cancer will have radiation therapy and then begin chemotherapy. Drug therapy will consist of a combination of doxorubicin, cyclophosphamide, and paclitaxel. What should the nurse include in the patient's teaching plan concerning the drug therapy? Select TWO (2) that apply.

Answer 1

Correct Answers:

Avoid large crowds and public places whenever possible
Take special care when shaving or brushing their teeth

Rationale :

🦠These chemotherapy agents can cause myelosuppression and neutropenia, which increase susceptibility to infection; avoiding crowds and people who are ill is an appropriate protective strategy during periods of reduced neutrophil counts.

🩸Thrombocytopenia can also occur during cytotoxic chemotherapy, increasing the patient's risk for bruising and bleeding.

🪥Clients at increased bleeding risk should use a soft toothbrush and exercise special care with oral hygiene to avoid traumatizing the gums.

🪒Using an electric shaver rather than a blade razor is also recommended when platelet suppression increases the risk of bleeding from minor cuts.

📌Core Message:

Chemotherapy-associated neutropenia and thrombocytopenia make infection avoidance and careful bleeding precautions essential patient teaching.

Answer 2

Correct Answers:

Monitoring the patient's urine output for signs of hematuria

Rationale :

🛡️Mesna is a cytoprotective medication specifically used to reduce the incidence of ifosfamide-induced hemorrhagic cystitis.

🩸Ifosfamide metabolites can injure the urinary bladder, producing hemorrhagic cystitis and hematuria.

🚽The absence or reduction of blood in the urine provides evidence that mesna is achieving its intended uroprotective effect.

💧Monitoring urinary findings is therefore more directly related to mesna effectiveness than gastrointestinal symptoms or pain assessment.

📌Core Message:

Mesna protects the urinary bladder from ifosfamide-induced hemorrhagic cystitis, so monitoring for hematuria evaluates its therapeutic effectiveness.

Answer 3

Correct Answers:

Probenecid

Rationale :

💊IV cidofovir must be administered with probenecid according to its prescribing information.

🛡️Probenecid reduces renal tubular exposure to cidofovir, helping decrease the substantial risk of cidofovir-associated nephrotoxicity.

💧Cidofovir therapy also requires intravenous saline prehydration as an additional nephroprotective measure.

🧪Because renal toxicity is a major dose-limiting concern with cidofovir, these protective interventions are integral to safe administration.

📌Core Message:

IV cidofovir is administered with probenecid and saline hydration to reduce the risk of serious nephrotoxicity.

Answer 4

Correct Answers:

Digoxin

Rationale :

💊This is a legacy pharmacology test-bank item whose expected answer is digoxin because older nursing references describe systemic azole antifungals as capable of increasing serum concentrations of interacting medications, including digoxin.

⚠️The intended teaching concept is that fluconazole inhibits drug-metabolizing pathways and therefore requires medication-interaction review when used with drugs having narrow therapeutic ranges.

📋Current fluconazole labeling documents numerous clinically important drug interactions, although digoxin is not prominently listed as a specific major interaction in the current label.

💧Current labeling also notes that hydrochlorothiazide increases fluconazole concentrations by about 40%, but specifically states that this magnitude does not normally require a fluconazole dosage change.

📌Core Message:

The exam-expected answer is digoxin, reflecting the broader principle that systemic azoles require careful review for clinically significant drug interactions.

Answer 5

Correct Answers:

Consult a drug guide to check for interactions

Rationale :

💊When multiple medications are scheduled together, the nurse should first determine whether there are clinically significant drug-drug interactions or compatibility concerns before administration.

🔍Medication safety requires nurses to assess for interactions, allergies, contraindications, and relevant clinical findings before giving the drugs.

🛡️Identifying an important interaction before medication preparation or administration can prevent avoidable adverse drug events.

📚A reliable drug reference therefore provides essential safety information before proceeding with the remaining medication-administration steps when several drugs are due simultaneously.

📌Core Message:

When several medications are due together, first verify drug interactions and compatibility before proceeding with administration.

Answer 6

Correct Answers:

1

Rationale :

💊The prescribed methylphenidate dose is 5 mg, and each available scored tablet contains 5 mg.

🧮The required calculation is 5 mg ÷ 5 mg/tablet, which produces 1 tablet.

✅Because the available tablet contains the exact prescribed dose, no tablet splitting is necessary.

📋The nurse should therefore administer 1 tablet for the ordered 5-mg dose.

📌Core Message:

When the prescribed and available strengths are both 5 mg, the correct dose is one tablet.

Answer 7

Correct Answers:

Unusual bruising and bleeding

Rationale :

🩸Unusual bruising or bleeding can indicate a serious systemic adverse reaction and warrants prompt healthcare-provider evaluation in a patient receiving systemic antifungal therapy.

🧪Systemic antifungal medications can produce significant hepatic or hematologic toxicity, depending on the specific agent, making unexpected bleeding clinically important.

🚨The exam item specifically uses unexplained bruising and bleeding as a warning manifestation requiring immediate reporting rather than routine monitoring.

🩺Prompt reporting allows assessment of liver function, coagulation status, and blood counts when clinically indicated.

📌Core Message:

Unexpected bruising or bleeding during systemic antifungal therapy requires prompt evaluation for potentially serious toxicity.

Answer 8

Correct Answers:

Take the medication on an empty stomach

Rationale :

💊Oral tetracycline absorption is reduced by food and certain dairy products, so administration away from meals improves absorption.

🥛Calcium-containing dairy products can bind tetracycline and interfere with gastrointestinal absorption.

💧Tetracycline capsules should also be taken with an adequate amount of water to reduce the risk of esophageal irritation and ulceration.

⏰Therefore, taking tetracycline on an empty stomach with sufficient water is the best instruction among the choices.

📌Core Message:

Oral tetracycline should be taken on an empty stomach with adequate water, while dairy products should be separated because they impair drug absorption.

Answer 9

Correct Answers:

245

Rationale :

🧮First determine the required volume using 671 mg ÷ 486 mg × 68 mL, which gives approximately 93.88 mL.

⏱️The prescribed infusion duration is 23 minutes, which must be converted when determining an hourly pump rate.

💧The rate calculation is 93.88 mL ÷ 23 minutes × 60 minutes/hour, which produces approximately 244.92 mL/hr.

✅Rounding to the nearest whole number gives 245 mL/hr.

📌Core Message:

The prescribed penicillin dose requires approximately 93.88 mL over 23 minutes, producing an IV pump setting of 245 mL/hr.

Answer 10

Correct Answers:

Monitor the urinalysis result

Rationale :

🚽Cyclophosphamide can cause hemorrhagic cystitis, hematuria, and other urinary-tract toxicity, making urinary assessment a major safety priority.

🩸Current prescribing information recommends regular examination of urinary sediment for erythrocytes and other evidence of urotoxicity.

💧Adequate hydration, frequent bladder emptying, and forced diuresis when appropriate can help decrease the frequency and severity of bladder toxicity.

🚨Because hemorrhagic cystitis can become severe or even fatal, monitoring urinalysis takes priority among the listed interventions.

📌Core Message:

Cyclophosphamide can cause hemorrhagic cystitis, making urinalysis monitoring for hematuria and urinary toxicity a priority nursing intervention.
