| # | Front | Back | Hint |
|---|---|---|---|
| 1 | Why should NSAIDs be used cautiously in patients with a history of peptic ulcer disease? | NSAIDs inhibit cyclooxygenase enzymes, reducing protective prostaglandins in the gastric mucosa, which increases the risk of gastrointestinal ulcers and bleeding, especially in susceptible individuals. | Think of prostaglandins as gastric protectors—NSAIDs block them. |
| 2 | What is a major contraindication for prescribing NSAIDs in patients with chronic kidney disease? | NSAIDs can impair renal blood flow by inhibiting prostaglandin synthesis, potentially worsening renal function and leading to acute kidney injury in patients with existing kidney impairment. | NSAIDs can 'dehydrate' the kidneys' blood supply. |
| 3 | Which drug class can increase the risk of bleeding when combined with NSAIDs? | Anticoagulants (e.g., warfarin) and antiplatelet agents (e.g., aspirin) increase bleeding risk when used concomitantly with NSAIDs due to additive effects on platelet function and coagulation pathways. | Think 'bleeding' with 'blood thinners' + NSAIDs. |
| 4 | Why are corticosteroids contraindicated in systemic fungal infections? | Corticosteroids suppress immune responses, which can exacerbate fungal infections and hinder the body's ability to combat the pathogen, making the infection worse. | Steroids suppress immunity—bad in infections. |
| 5 | What caution should be taken when prescribing NSAIDs to elderly patients? | Elderly patients have increased susceptibility to gastrointestinal bleeding, renal impairment, and cardiovascular risks from NSAIDs; dose adjustments and careful monitoring are essential. | Elderly = higher risk, lower dose. |
| 6 | Which medications can increase the plasma levels of corticosteroids, potentially leading to toxicity? | CYP3A4 inhibitors, such as ketoconazole and ritonavir, can decrease corticosteroid metabolism, increasing plasma levels and risk of systemic side effects like osteoporosis or hyperglycemia. | Inhibit breakdown, increase effects. |
| 7 | Why should NSAIDs be avoided in patients taking ACE inhibitors or diuretics? | NSAIDs can reduce the antihypertensive effects of ACE inhibitors and diuretics and may precipitate acute kidney injury by decreasing renal perfusion through prostaglandin inhibition. | NSAIDs + blood pressure meds = kidney risk. |
| 8 | What is the primary concern when prescribing steroids to diabetic patients? | Steroids can induce hyperglycemia by increasing gluconeogenesis and insulin resistance, complicating diabetes management. | Steroids raise blood sugar—monitor closely. |
| 9 | How does concurrent use of NSAIDs and lithium increase the risk of lithium toxicity? | NSAIDs decrease renal clearance of lithium by reducing prostaglandin-mediated renal perfusion, leading to increased lithium levels and potential toxicity. | NSAIDs + lithium = kidney retention. |
| 10 | What are the risks of using corticosteroids in patients with active infections? | Corticosteroids suppress immune responses, which can worsen infections, delay healing, and increase susceptibility to secondary infections. | Steroids can 'hide' infections but worsen them. |
| 11 | Why is it important to taper corticosteroids rather than abruptly stopping them? | Tapering prevents adrenal suppression by allowing the HPA axis to recover and produce endogenous cortisol, avoiding adrenal insufficiency. | Gradually reduce to let your adrenal glands wake up. |
| 12 | Which drug interaction can lead to increased cardiovascular risk when combining NSAIDs with certain antihypertensives? | NSAIDs can diminish the cardioprotective effects of antihypertensives like beta-blockers and ACE inhibitors, and increase the risk of hypertension and cardiovascular events. | NSAIDs may counteract blood pressure meds. |
| 13 | What is a key contraindication for using systemic corticosteroids in patients with live vaccines? | Corticosteroids suppress immune responses, reducing vaccine efficacy and increasing the risk of vaccine-derived infection, so live vaccines are contraindicated during systemic steroid therapy. | Steroids weaken immune defenses—no live vaccines. |
| 14 | Which NSAID is preferred in patients with cardiovascular risk factors, and why? | Naproxen is preferred because it has a comparatively lower cardiovascular risk profile among NSAIDs, but caution is still advised. | Choose 'Naproxen' for fewer heart risks. |
| 15 | What is the significance of monitoring renal function in patients on long-term NSAID therapy? | Prolonged NSAID use can impair renal function, so regular monitoring of serum creatinine and estimated glomerular filtration rate (eGFR) is essential to detect early kidney impairment. | Check kidneys regularly with NSAIDs. |
| 16 | Why should corticosteroids be used cautiously in patients with osteoporosis? | Chronic corticosteroid use decreases bone mineral density, increasing fracture risk; calcium and vitamin D supplementation and bone health monitoring are recommended. | Steroids weaken bones. |
| 17 | Which anti-inflammatory agent is contraindicated in patients with hypersensitivity to aspirin? | Other NSAIDs that are chemically related to aspirin, such as ibuprofen or naproxen, are contraindicated due to cross-reactivity and risk of allergic reactions. | Aspirin allergy? Avoid related NSAIDs. |
| 18 | What should be considered when prescribing corticosteroids to pregnant women? | Corticosteroids cross the placenta; they should be used cautiously, at the lowest effective dose, and only if benefits outweigh risks, as they may affect fetal development. | Use with caution during pregnancy. |
| 19 | How can concomitant use of NSAIDs and steroids increase gastrointestinal risk? | Both drugs independently increase gastrointestinal ulceration and bleeding risk; their combination amplifies this risk, necessitating gastroprotective strategies if used together. | NSAIDs + steroids = GI caution. |
| 20 | What is the role of proton pump inhibitors (PPIs) in patients taking NSAIDs? | PPIs reduce gastric acid secretion, decreasing the risk of NSAID-induced gastric ulcers and bleeding in high-risk patients. | PPIs protect stomach during NSAID therapy. |
