Q1 Question 1 of 75
A 68-year-old client with chronic kidney disease is prescribed a medication that is
primarily eliminated by the kidneys. The nurse reviews the client's most recent
creatinine clearance of 35 mL/min. What is the nurse's priority action before
administering the dose?
A. Consult the provider to discuss a possible dose reduction.
B. Administer the medication with a full glass of water.
C. Hold the medication until renal function improves.
D. Give the medication with food to enhance absorption.
Correct Answer: A
Rationale:
In chronic kidney disease, reduced creatinine clearance impairs drug elimination, increasing the risk of
toxicity. The nurse should consult the provider to discuss dose adjustment. Holding the medication
entirely may interrupt necessary therapy, and giving with food or water does not address the renal
clearance issue.

, Q2 Question 2 of 75
A nurse is caring for a client receiving a new antibiotic. The client asks why the
nurse checks their wristband and asks for their name and date of birth before
every dose. What is the best response by the nurse?
A. It is a hospital policy to verify identity before all medications.
B. Checking identity ensures the right client receives the right medication at the right
time.
C. The pharmacy requires two identifiers for every medication administration.
D. It helps prevent allergic reactions to new medications.
Correct Answer: B
Rationale:
The five rights of medication administration include the right client, right drug, right dose, right route, and
right time. Using two identifiers directly supports the right client. While policy and pharmacy
requirements may exist, the best explanation focuses on client safety and the five rights.
Q3 Question 3 of 75
A client with a history of peptic ulcer disease is prescribed an enteric-coated
tablet. The client tells the nurse they have difficulty swallowing pills and asks if
they can crush the tablet. What is the nurse's best response?
A. Crushing the tablet is acceptable if mixed with applesauce.
B. Enteric-coated tablets should not be crushed because it destroys the protective
coating.
C. You may dissolve the tablet in warm water before drinking it.
D. Crushing is fine as long as you take it with a full meal.
Correct Answer: B
Rationale:
Enteric coatings protect the drug from gastric acid and prevent gastric irritation. Crushing destroys this
coating, potentially causing drug degradation and gastric mucosal damage. The nurse should contact
the provider to request an alternative formulation.

, Q4 Question 4 of 75
A nurse is reviewing a client's medication list and notes that the client takes both
warfarin and a daily multivitamin containing vitamin K. What is the most important
nursing implication regarding this combination?
A. The multivitamin will enhance the anticoagulant effect of warfarin.
B. Vitamin K can antagonize the therapeutic effect of warfarin and alter INR values.
C. The combination increases the risk of gastrointestinal bleeding.
D. Warfarin absorption is reduced when taken with multivitamins.
Correct Answer: B
Rationale:
Warfarin works by inhibiting vitamin K-dependent clotting factors. Supplemental vitamin K can
counteract warfarin's effect, leading to subtherapeutic anticoagulation. The nurse should educate the
client to maintain consistent vitamin K intake and monitor INR closely.
Q5 Question 5 of 75
A 42-year-old client with asthma is prescribed a medication that acts as a beta-2
adrenergic agonist. The nurse understands that the primary therapeutic effect of
this drug class is to:
A. Reduce airway inflammation by suppressing the immune response.
B. Dilate bronchial smooth muscle by stimulating beta-2 receptors.
C. Block histamine release from mast cells in the lungs.
D. Thin mucus secretions to improve airway clearance.
Correct Answer: B
Rationale:
Beta-2 adrenergic agonists such as albuterol bind to beta-2 receptors on bronchial smooth muscle,
causing relaxation and bronchodilation. This is the primary mechanism for relieving acute
bronchospasm. Anti-inflammatory effects are achieved by corticosteroids, not beta-2 agonists.
