APHON CHEMO CERTIFICATION EXAM 2025 QUESTIONS
WITH 100% SOLVED ANSWERS!!
Question 1
A pediatric patient receiving chemotherapy develops a fever of 101.5°F
(38.6°C) and neutropenia. What is the most immediate nursing priority?
A) Administer a prescribed antipyretic.
B) Obtain blood cultures and administer ordered broad-spectrum antibiotics.
C) Increase oral fluid intake to prevent dehydration.
D) Assess for signs of mucositis.
E) Provide comfort measures and recheck temperature in 4 hours.
Correct Answer: B) Obtain blood cultures and administer ordered
broad-spectrum antibiotics.
Rationale: Fever in a neutropenic patient is a medical emergency
requiring prompt blood cultures to identify potential pathogens and
immediate administration of broad-spectrum antibiotics to prevent
rapid progression to sepsis and septic shock, which can be life-
threatening in immunocompromised children.
Question 2
When administering a vesicant chemotherapeutic agent peripherally, which
nursing action is crucial to prevent extravasation?
A) Administer the medication as a rapid IV push.
B) Ensure the IV site is in an area of flexion.
C) Assess for blood return every 5-10 mL of drug administered.
D) Use a 24-gauge catheter in a large vein.
E) Apply a warm compress to the site immediately after insertion.
Correct Answer: C) Assess for blood return every 5-10 mL of drug
administered.
Rationale: Continuous vigilant assessment for blood return every 5-
10 mL (or per institutional policy) during a peripheral vesicant
infusion is essential to detect early signs of extravasation.
Extravasation can cause severe tissue damage, and early detection
allows for intervention to minimize harm.
,Question 3
A nurse is preparing to administer a hazardous chemotherapeutic agent.
Which Personal Protective Equipment (PPE) is essential?
A) Standard surgical mask, gloves, and gown.
B) N95 respirator, sterile gloves, and isolation gown.
C) Double gloves, impermeable gown, and eye/face protection.
D) Single gloves, fluid-resistant gown, and surgical mask.
E) Clean gloves and a regular hospital uniform.
Correct Answer: C) Double gloves, impermeable gown, and eye/face
protection.
Rationale: APHON guidelines and OSHA standards require specific
PPE for safe handling of hazardous drugs, including double gloves
(chemotherapy-tested), an impermeable gown, and eye/face
protection (e.g., goggles or face shield) to prevent exposure during
preparation and administration.
Question 4
Which class of chemotherapeutic agents primarily works by interfering with
DNA replication during the S-phase of the cell cycle?
A) Alkylating agents
B) Antimetabolites
C) Anthracyclines
D) Topoisomerase inhibitors
E) Vinca alkaloids
Correct Answer: B) Antimetabolites.
Rationale: Antimetabolites are structurally similar to normal
metabolites and interfere with nucleic acid synthesis (DNA and RNA)
during the S-phase, thus disrupting DNA replication and cell
proliferation.
Question 5
A common and potentially life-threatening toxicity associated with
,methotrexate administration, particularly with high doses, is:
A) Cardiotoxicity
B) Nephrotoxicity
C) Ototoxicity
D) Peripheral neuropathy
E) Pulmonary fibrosis
Correct Answer: B) Nephrotoxicity.
Rationale: Methotrexate can precipitate in the renal tubules, leading
to acute kidney injury. Hydration and alkalinization of urine are
critical to prevent this, and leucovorin rescue is often used to
minimize systemic toxicity.
Question 6
What is the primary rationale for administering multiple chemotherapy
agents in combination therapy?
A) To reduce the total duration of treatment.
B) To target different phases of the cell cycle and overcome drug resistance.
C) To minimize the need for central venous access.
D) To decrease the overall cost of treatment.
E) To allow for easier patient and family scheduling.
Correct Answer: B) To target different phases of the cell cycle and
overcome drug resistance.
Rationale: Combination chemotherapy utilizes agents with different
mechanisms of action, targeting various phases of the cell cycle and
employing non-overlapping toxicities. This strategy aims to
maximize tumor cell kill, minimize resistance, and improve efficacy
compared to single-agent therapy.
Question 7
A child receiving doxorubicin is at risk for which organ-specific long-term
toxicity?
A) Renal dysfunction
, B) Ototoxicity
C) Cardiotoxicity
D) Hepatotoxicity
E) Pulmonary fibrosis
Correct Answer: C) Cardiotoxicity.
Rationale: Doxorubicin is an anthracycline known for its dose-
dependent cardiotoxicity, which can manifest as cardiomyopathy
and heart failure, sometimes many years after treatment.
Question 8
Before administering a new chemotherapy regimen to a pediatric patient,
what is a critical component of the pretreatment assessment by the nurse?
A) Confirming the patient's favorite meal.
B) Verifying recent weight, height, and body surface area (BSA) calculations.
C) Reviewing the patient's social media history.
D) Checking the last dental appointment date.
E) Obtaining a detailed family vacation history.
Correct Answer: B) Verifying recent weight, height, and body surface
area (BSA) calculations.
Rationale: Chemotherapy doses are often calculated based on a
patient's current body surface area (BSA), which requires accurate
weight and height measurements. Verification is essential for safe
and effective dosing in pediatric patients.
Question 9
What is the nadir in chemotherapy treatment?
A) The highest point of white blood cell count after chemotherapy.
B) The period when the patient feels the most energetic.
C) The lowest point of blood cell counts (WBCs, platelets, RBCs) following
chemotherapy.
D) The time of maximum tumor shrinkage.
E) The final stage of treatment.
