9 MUST KNOW MEDs for Nclex

Preparing for the NCLEX means not only understanding nursing concepts but also being well-versed in key medications that frequently appear in exam questions. This guide highlights nine essential meds you need to know, offering practical tips that reflect real nursing scenarios. Insulin Regular (Humulin R) is the only insulin that can be given intravenously, with an onset of 30-60 minutes. Always check blood sugar levels before administration to avoid hypoglycemia and monitor potassium, as hypokalemia can occur. Furosemide (Lasix) is a loop diuretic known for its rapid fluid removal. Administer it slowly via IV push to prevent ototoxicity. Watch for hypokalemia and dehydration, which are common side effects. Albuterol is your go-to rescue inhaler for bronchospasm relief. Be aware of potential side effects like tachycardia and tremors. It’s often used prior to steroids in respiratory conditions to maximize effectiveness. Morphine, a powerful opioid analgesic, requires careful respiratory monitoring as respiratory depression is a serious risk. If the respiratory rate falls below 12 breaths per minute, withhold the med. Constipation is another common side effect to manage. Levothyroxine treats hypothyroidism and should be taken in the morning on an empty stomach to enhance absorption. Overdosage indications include signs of hyperthyroidism. Metformin is a first-line oral medication for type 2 diabetes but can rarely cause lactic acidosis—a potentially fatal condition. It’s critical to hold Metformin before procedures involving contrast dye to avoid complications. Ondansetron (Zofran) is an effective anti-nausea medication that can prolong the QT interval; therefore, ECG monitoring is advised when given IV. Lisinopril, an ACE inhibitor, is widely used for hypertension and heart failure. Monitor potassium closely to avoid hyperkalemia, and watch for symptoms of cough or angioedema. Note that Lisinopril is contraindicated in pregnancy. Understanding these medications beyond rote memorization—knowing their administration considerations, side effects, and nursing implications—will build your confidence and competence for the NCLEX exam. Integrating this medication knowledge with patient assessment, safety precautions, and effective communication exemplifies the quality care expected of licensed nurses.
