What is the relationship between Calcium and Phosphorus? -CORRECTANSWER They
have an inverse relationship.
What is the relationship between Magnesium and Phosphorus? -CORRECTANSWER
They have an inverse relationship.
What is the relationship between Calcium and Vitamin D? -CORRECTANSWER They
have a similar relationship.
What is the relationship between Magnesium and Calcium? -CORRECTANSWER They

,What does the suffix -olol indicate in pharmacology? -CORRECTANSWER It indicates
a beta-blocker medication.
What does the suffix -pril indicate in pharmacology? -CORRECTANSWER It indicates
an ACE inhibitor medication.
What is the mnemonic for the stages of pharmacokinetics? -CORRECTANSWER
ADME: Absorption, Distribution, Metabolism, and Excretion.
What is the first-pass effect? -CORRECTANSWER The process where the liver
metabolizes oral medications before they reach systemic circulation, reducing their
bioavailability.
Which route of drug administration is the fastest? -CORRECTANSWER Intravenous
(IV) administration, as it delivers the drug directly into the bloodstream.
What is the significance of protein-binding in drug distribution? -CORRECTANSWER
Highly protein-bound drugs stay in circulation longer and may interact with other protein-
bound medications.
Where does the majority of drug metabolism occur? -CORRECTANSWER In the liver,
primarily via CYP450 enzymes.
,What is the primary organ responsible for drug excretion? -CORRECTANSWER The
kidneys; therefore, BUN and creatinine levels should be monitored to assess function.
What is a drug agonist? -CORRECTANSWER A substance that binds to and activates
cell receptors to trigger a physiological response.
What is a drug antagonist? -CORRECTANSWER A substance that binds to cell
receptors and blocks them, preventing a physiological response.
What is the therapeutic index? -CORRECTANSWER The safety margin of a drug,
representing the range between a therapeutic dose and a toxic dose.
What is a drug's half-life? -CORRECTANSWER The time required for half of the drug's
concentration to be eliminated from the body.
What is bioavailability? -CORRECTANSWER The proportion of an administered drug
that successfully reaches systemic circulation and is available for action.
What is the mnemonic for beta-blocker effects? -CORRECTANSWER LOL: Lower heart
rate, Open airways cautiously, Lowers blood pressure.
, What is the mnemonic for ACE inhibitor effects? -CORRECTANSWER PRIL: Please
Remember It Lowers blood pressure.
What is a common safety alert for loop diuretics? -CORRECTANSWER Risk of
hypokalemia.
What is a common safety alert for Clozapine? -CORRECTANSWER Risk of
agranulocytosis.
What must a nurse check before administering Digoxin? -CORRECTANSWER The
patient's apical pulse.
What is the consequence of slow drug metabolism in the liver? -CORRECTANSWER
The drug may accumulate in the body, leading to an increased risk of toxicity.
What is the primary use of ACE inhibitors (suffix -pril)? -CORRECTANSWER Treatment
of hypertension and heart failure.
What is the primary use of Beta-blockers (suffix -lol)? -CORRECTANSWER Treatment
of hypertension and arrhythmias.
What is the primary use of ARBs (suffix -sartan)? -CORRECTANSWER Treatment of
hypertension.
