Question

A female client with mild depression reports to the nurse recently starting St. John's wort. Which information provided by the client requires further instruction?

Answer 1

Correct Answers:

Another form of contraception is not needed.

Rationale :

⭐ St. John’s Wort is known to interact with hormonal contraceptives, including birth control pills, by inducing CYP450 enzymes, which reduces their effectiveness.

⭐ This can lead to unintended pregnancies, making it essential for clients to use a backup form of contraception.

⭐ The nurse should provide additional teaching when the client assumes no other contraceptive method is necessary.

⭐ This is a critical safety issue requiring immediate clarification.

Answer 2

Correct Answers:

Toasted wheat bread and jelly.

Rationale :

✴ Tetracyclines should be taken with non-dairy, low-calcium foods to minimize gastrointestinal upset while preserving absorption.

✴ Dairy products like milk, cheese, or yogurt bind with tetracycline and reduce its effectiveness.

✴ Toasted bread and jelly provide a low-fat, non-dairy option that reduces GI irritation without compromising drug absorption.

✴ This food pairing supports therapeutic action and tolerability.

Answer 3

Correct Answers:

Platelet count of 100,000/mm³ (100 x 10^9/L).

Rationale :

💫 Enoxaparin, a low molecular weight heparin, can cause heparin-induced thrombocytopenia (HIT), which is a serious adverse effect.

💫 A platelet count of 100,000/mm³ is below the normal reference range and suggests a potential complication.

💫 The nurse must report this finding immediately to prevent bleeding risks or thrombotic complications.

💫 The other labs are within normal limits and don’t indicate urgent concern.

Answer 4

Correct Answers:

Feverfew may interact with aspirin or non-steroidal anti- inflammatory drugs.

Rationale :

✨ Feverfew has antiplatelet properties and can potentiate bleeding when combined with aspirin or NSAIDs.

✨ Clients should be warned about the increased risk of gastrointestinal or internal bleeding with concurrent use.

✨ This interaction is clinically significant and must be included in patient education.

✨ Clients using herbal remedies need to be monitored for drug-herb interactions.

Answer 5

Correct Answers:

Body mass index.

Rationale :

🎯 Orlistat works by inhibiting fat absorption and is prescribed for weight loss in overweight individuals.

🎯 The best way to monitor effectiveness is by tracking body mass index (BMI) over time.

🎯 BMI reflects changes in weight relative to height and shows whether the drug is helping achieve weight goals.

🎯 Calorie tracking is helpful but does not replace objective outcome measurement like BMI.

Answer 6

Correct Answers:

Pepperoni pizza.

Rationale :

🌟 Phenelzine is a monoamine oxidase inhibitor (MAOI), and clients must avoid tyramine-rich foods to prevent hypertensive crisis.

🌟 Aged meats, like pepperoni, are high in tyramine and are strictly contraindicated.

🌟 Consumption of such foods can lead to severe hypertension, headache, and stroke.

🌟 The nurse should educate the client thoroughly on MAOI dietary restrictions.

Answer 7

Correct Answers:

Apical pulse rate of 50 beats/minute.

Rationale :

🟢 Digoxin slows the heart rate by increasing vagal tone and is held if the apical pulse is <60 bpm.

🟢 A pulse rate of 50 bpm is bradycardic and may lead to cardiac compromise or toxicity.

🟢 The nurse should withhold the dose and notify the provider.

🟢 Monitoring the apical pulse is standard practice before digoxin administration.

Answer 8

Correct Answers:

Avoid hazardous activities until symptoms subside.

Rationale :

💥 Baclofen can cause sedation, dizziness, and fatigue, particularly during initiation of therapy.

💥 Clients should be instructed to avoid driving, operating machinery, or engaging in risky tasks until they know how the medication affects them.

💥 These side effects typically diminish over time as the body adjusts.

💥 Safety is the priority until side effects are better tolerated.

Answer 9

Correct Answers:

Denies having coughing spells.

Rationale :

🎇 Benzonatate is a non-opioid antitussive that suppresses the cough reflex by anesthetizing stretch receptors in the respiratory tract.

🎇 If the client no longer experiences coughing spells, the drug is considered effective.

🎇 This is the intended outcome for a symptom-focused medication like benzonatate.

🎇 Other effects like sleep or mucus clearance are secondary or unrelated.

Answer 10

Correct Answers:

Eliminate use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Rationale :

🎆 Lithium has a narrow therapeutic index, and its serum level can be increased by NSAIDs, leading to toxicity.

🎆 NSAIDs reduce renal clearance of lithium, which can cause neurologic symptoms, tremors, confusion, and even seizures.

🎆 Clients must be taught to avoid OTC NSAIDs and consult their provider before taking new medications.

🎆 This is a key point in lithium safety education.
