NUR 210 EXAM 1 MODULES 1-3 QUESTIONS COMPLETE WITH 100% VERIFIED ANSWERS 1. A nurse is preparing to administer a medication. Which of the following represents the correct order of the "3 checks" of drug administration? A) Bedside, MAR, pulling medication B) Pulling medication, MAR, bedside C) MAR, bedside, pulling medication D) Bedside, pulling medication, MAR Correct Answer: B) Pulling medication, MAR, bedside Rationale: The 3 checks of drug administration must be performed in this specific order: (1) when pulling the medication from the drawer or shelf, (2) when comparing the medication to the MAR (medication administration record), and (3) at the bedside before administering to the client. This systematic approach helps prevent medication errors. ________________________________________ 2. A client is prescribed a medication that is highly protein bound. Which laboratory value should the nurse monitor closely? A) Hemoglobin B) Platelet count C) Albumin D) White blood cell count Correct Answer: C) Albumin Rationale: Albumin is the primary protein in blood that binds to medications. When albumin levels are decreased, there are fewer protein-binding sites available, meaning more free (unbound) drug is circulated. This can lead to drug toxicity, especially with highly protein-bound medications. Older adults, malnourished individuals, and those with liver or kidney disease commonly have low albumin levels. ________________________________________ 3. A client is receiving an intravenous (IV) medication. How long does it typically take for an IV medication to be absorbed? A) 1-2 hours B) 30-60 minutes C) 2-4 hours D) 4-6 hours Correct Answer: B) 30-60 minutes Rationale: IV medications are administered directly into the bloodstream, bypassing the GI tract and first-pass effect through the liver. This route provides the fastest absorption, typically occurring within 30-60 minutes. Oral medications take longer (2-4 hours) because they must pass through the GI system, and IM injections take 1-2 hours. ________________________________________ 4. The nurse is teaching a client about oral medication administration. Which statement by the client indicates a need for further teaching? A) "I should take my enteric-coated aspirin with food to prevent stomach upset." B) "Liquid medications are absorbed faster than solid medications." C) "Food can interfere with the absorption of some medications." D) "Extended-release medications should not be crushed." Correct Answer: A) "I should take my enteric-coated aspirin with food to prevent stomach upset." Rationale: Enteric-coated medications are designed to resist disintegration until they reach the small intestine. They should NOT be crushed, and while they may be taken with food, the client's statement implies they understand enteric coating is for stomach protection. Actually, enteric coating prevents the medication from dissolving in the stomach to protect the stomach lining, not to be taken with food to prevent upset. The other statements are correct. ________________________________________ 5. Which medication classification is the only COX-2 inhibitor that does not produce GI bleeding? A) Ibuprofen B) Aspirin C) Celecoxib D) Morphine Correct Answer: C) Celecoxib Rationale: Celecoxib is a COX-2 selective inhibitor that works specifically on COX-2 enzymes (responsible for pain and inflammation) without affecting COX-1 enzymes (which protect the stomach lining and regulate platelets). This means it does not cause the GI bleeding and ulcers associated with non-selective NSAIDs. However, it carries an increased risk of heart attack and stroke, so it must be used cautiously in patients with cardiac conditions. ________________________________________ 6. A client is prescribed an opioid analgesic. Which adverse effect should the nurse monitor for as a priority? A) Hypertension B) Diarrhea C) Respiratory depression D) Tachycardia Correct Answer: C) Respiratory depression Rationale: Respiratory depression is the most serious adverse effect of opioid analgesics and is the priority concern. Opioids act on the CNS to decrease the respiratory rate and depth. Other adverse effects include constipation, orthostatic hypotension, sedation, and urinary retention. The nurse should always monitor respiratory rate before and after administering opioids. ________________________________________ 7. The nurse is administering an IM injection. How long does it typically take for an intramuscular medication to be absorbed? A) 30-60 minutes B) 1-2 hours C) 2-4 hours D) 4-6 hours Correct Answer: B) 1-2 hours
