Approved A+ Solutions
Section 1: Pharmaceutics (25 Questions)
Question 1 (Multiple-Choice)
A nurse is preparing to administer a medication via the intramuscular route. What is the
maximum volume for an adult deltoid injection?
A) 5 mL
B) 1 mL
C) 3 mL
D) 10 mL
Rationale: The deltoid muscle can safely accommodate up to 1 mL to prevent tissue damage,
per 2025 pharmacology guidelines.
Question 2 (Multiple-Choice)
Which administration route provides the fastest onset of action?
A) Oral
B) Subcutaneous
C) Intravenous
D) Intramuscular
Rationale: Intravenous administration delivers drugs directly into the bloodstream, per Portage
Learning pharmacology standards.
Question 3 (Multiple-Choice)
A nurse is administering a transdermal patch. What is a key teaching point?
, 2
A) Apply to broken skin
B) Rotate application sites
C) Leave on for 24 hours regardless of drug
D) Apply multiple patches at once
Rationale: Rotating sites prevents skin irritation, per 2025 nursing guidelines.
Question 4 (NGN: Case Study)
Case Study: A client is prescribed a fentanyl transdermal patch for chronic pain. The nurse notes
the previous patch is still in place. What is the priority action?
A) Apply the new patch next to the old one
B) Remove the old patch
C) Leave both patches in place
D) Increase the dose
Rationale: Removing the old patch prevents overdose, per 2025 pharmacology standards.
Question 5 (Multiple-Choice)
What is the purpose of enteric-coated tablets?
A) Increase gastric irritation
B) Protect the stomach
C) Speed up absorption
D) Reduce drug potency
Rationale: Enteric coatings prevent gastric irritation and drug breakdown, per Portage Learning
guidelines.
Question 6 (Multiple-Choice)
A nurse is administering an IV medication. What prevents infiltration?
A) Check IV site for patency
B) Administer rapidly
C) Ignore site redness
D) Use a small-gauge needle
Rationale: Checking patency ensures proper IV function, per 2025 pharmacology guidelines.
Question 7 (Multiple-Choice)
Which route is most affected by first-pass metabolism?
, 3
A) Oral
B) Intravenous
C) Subcutaneous
D) Transdermal
Rationale: Oral drugs undergo first-pass metabolism in the liver, per Portage Learning
standards.
Question 8 (Multiple-Choice)
A nurse is preparing a subcutaneous injection. What is the maximum volume for an adult?
A) 0.5 mL
B) 1 mL
C) 3 mL
D) 5 mL
Rationale: Subcutaneous injections are limited to 1 mL to prevent tissue damage, per 2025
guidelines.
Question 9 (Multiple-Choice)
What is a key consideration when administering eye drops?
A) Apply to the cornea directly
B) Press the nasolacrimal duct
C) Use multiple drops at once
D) Store at room temperature
Rationale: Pressing the nasolacrimal duct prevents systemic absorption, per pharmacology
standards.
Question 10 (NGN: Select-All-That-Apply)
Which actions ensure safe IV medication administration? (Select all that apply.)
A) Verify compatibility
B) Use two patient identifiers
C) Administer without checking rate
D) Monitor for adverse reactions
E) Reuse syringes
Answer: A, B, D
Rationale: Verifying compatibility, using identifiers, and monitoring reactions ensure safety, per
2025 guidelines.
