Question

A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?

Answer 1

Correct Answers:

Use an additional form of contraception.

Rationale :

💊Erythromycin can interact with oral contraceptives, potentially reducing their effectiveness due to changes in hepatic enzyme activity.

🔄This interaction increases the risk of unintended pregnancy, making additional contraception necessary during concurrent use.

📢Simply spacing the medications or discontinuing the contraceptive does not prevent the risk of pregnancy and could cause hormonal imbalance.

🛡️The safest and most effective nursing instruction is to use a backup form of contraception, such as condoms, while taking erythromycin.

📌Core Message

Always advise clients on oral contraceptives to use additional protection when prescribed enzyme-affecting antibiotics like erythromycin.

Answer 2

Correct Answers:

Explain that the client should not use the discus more than twice daily.

Rationale :

📅The fluticasone-salmeterol discus is a maintenance inhaler, designed to be used twice daily, about 12 hours apart.

💨Using it more often can increase the risk of side effects such as oral thrush or systemic steroid effects.

⛔It is not meant for acute relief, and overuse does not enhance effectiveness but poses potential harm.

📚Educating caregivers about correct frequency helps ensure safe and effective asthma management.

📌Core Message

Combination inhalers like fluticasone-salmeterol should be used twice daily for chronic asthma control, not more frequently or during attacks.

Answer 3

Correct Answers:

Antiretroviral medication prevents the transmission of the virus.

Rationale :

💉Antiretroviral therapy (ART) reduces viral load, which decreases the risk of transmission but does not eliminate it entirely.

📉While achieving an undetectable viral load significantly lowers the likelihood of sexual transmission, it does not guarantee total prevention.

🧪Clients must understand that ART is not a cure, and safe practices, such as condom use, are still recommended.

🗣️This statement reflects a misunderstanding and needs further clarification from the nurse.

📌Core Message

ART can make HIV undetectable but does not guarantee non-transmission—educating on safe practices remains essential.

Answer 4

Correct Answers:

Rapid weight gain.

Rationale :

📈Gabapentin can cause fluid retention, and rapid weight gain may signal worsening edema or cardiovascular compromise.

🚩This side effect requires immediate reporting, especially in clients with underlying heart or kidney issues.

🧍Other common side effects like dizziness and sedation are expected and not as urgent.

🛑Monitoring weight changes ensures the early detection of serious complications related to gabapentin.

📌Core Message

Report rapid weight gain with gabapentin use, as it may signal fluid overload or systemic complications.

Answer 5

Correct Answers:

Double the dose if a dose is missed.

Rationale :

⏱️Doubling a dose of allopurinol can increase toxicity risk and should be strictly avoided.

💊Clients should be instructed to take the missed dose if remembered soon, or skip it if the next dose is near.

⚠️Allopurinol is used to prevent gout attacks, not for immediate relief, so strict dosing is crucial.

📘Clear guidance ensures medication safety and proper disease management.

📌Core Message

Never double allopurinol doses; reinforce safe medication routines to avoid toxicity.

Answer 6

Correct Answers:

Chronic alcoholism.

Rationale :

🍺Alcohol combined with diclofenac increases the risk of gastric bleeding and liver damage.

🧪Diclofenac is hepatotoxic and ulcerogenic, especially when taken with alcohol.

🔍Clients with a history of chronic alcoholism are at greater risk for serious NSAID-related adverse effects.

📋This history should alter prescribing decisions and guide the nurse in close monitoring.

📌Core Message

Chronic alcohol use significantly increases the risk of NSAID complications, especially with diclofenac.

Answer 7

Correct Answers:

Determine presence of abdominal pain.

Rationale :

⚠️Long-term ibuprofen use is associated with peptic ulcers and GI bleeding, with abdominal pain as an early sign.

🧪NSAIDs inhibit prostaglandins, which protect the gastric lining, making this a high-risk medication.

👂Early assessment for GI symptoms helps prevent severe bleeding or perforation.

🔍This is a priority assessment over pulse or pain scoring, which may not reflect internal damage.

📌Core Message

Abdominal pain is an important red flag for NSAID-induced GI complications.

Answer 8

Correct Answers:

Potassium level of 3.2 mEq/L (3.2 mmol/L).

Rationale :

⚡Low potassium increases the risk of digoxin toxicity, which can lead to life-threatening arrhythmias.

🔬Digoxin and potassium compete for the same binding sites; low K+ enhances digoxin's effect.

🚨This value is critically low and needs urgent correction and provider notification.

📋All other lab values fall within or near the normal range, making potassium the immediate concern.

📌Core Message

Hypokalemia is a key trigger for digoxin toxicity, requiring immediate intervention.

Answer 9

Correct Answers:

Hypertension.

Rationale :

🧬Phenylephrine is a vasoconstrictor, which can raise blood pressure.

📈For hypertensive patients, this effect may cause dangerous elevations in BP.

🛑This makes hypertension a contraindication or cautionary condition requiring provider review.

💬The nurse should withhold the drug and consult the provider before administration.

📌Core Message

Phenylephrine should be used cautiously in hypertensive clients due to vasoconstrictive effects.

Answer 10

Correct Answers:

Body mass index (BMI).

Rationale :

⚖️BMI is a reliable measure to track weight changes over time in response to orlistat.

🔄Orlistat works by blocking fat absorption, and BMI reflects how well it supports weight loss goals.

📏It is an objective, measurable outcome and more directly correlates with medication efficacy than mood or labs.

🧾Tracking BMI over weeks allows the nurse to evaluate treatment effectiveness clearly.

📌Core Message

BMI is the best indicator to assess orlistat's effectiveness in promoting weight loss.
