Certified Foundational Perioperative Nurse (CFPN®) — Questions and Answers

Question 1: In relation to artificial nails worn by perioperative staff, the Joint Commission, the Association of PeriOperative Registered Nurses (AORN), the Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO) hold the following positions:

properly maintained artificial nails harbor fewer microorganisms than natural nails.
artificial nails are safe when worn under double gloves.
artificial nails present no registered concerns.
artificial nails must not be worn in the OR (Correct answer)

Correct answer: artificial nails must not be worn in the OR

Artificial nail use is discouraged by the AORN, CDC, and WHO because it promotes bacterial and fungal colonization of the hands. Even after properly performing a preoperative surgical scrub, perioperative workers with artificial nails still carry Gram-negative bacteria and yeast.

Question 2: According to the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP), which category represents an error that reached the patient and caused death?

Category E
Category G
Category B
Category I (Correct answer)

Correct answer: Category I

NCC MERP Category I represents errors that may have contributed to or resulted in patient death.

Question 3: When a discrepancy is found in controlled substance counts, what is the first step the forensic pharmacy nurse should take?

Resolve the discrepancy internally before reporting
Assume it was a counting error and recount
Document the discrepancy and report it to the supervisor and pharmacy immediately (Correct answer)
Notify the patient whose medication is involved

Correct answer: Document the discrepancy and report it to the supervisor and pharmacy immediately

Prompt documentation and reporting triggers the formal investigation process and preserves chain of accountability.

Question 4: Which analytical method is considered the gold standard for confirming positive immunoassay drug screen results in forensic toxicology?

Enzyme-linked immunosorbent assay (ELISA)
High-performance liquid chromatography (HPLC) alone
Gas chromatography-mass spectrometry (GC-MS) (Correct answer)
Thin-layer chromatography (TLC)

Correct answer: Gas chromatography-mass spectrometry (GC-MS)

GC-MS is the confirmatory gold standard because it identifies drugs by both chromatographic retention time and mass spectral fragmentation pattern, providing definitive identification.

Question 5: All of the following, WITH THE EXCEPTION OF?, are among the important fields of knowledge for the perioperative nurse.

endotracheal tube insertion and internal physical landmarks. (Correct answer)
anatomy.

Correct answer: endotracheal tube insertion and internal physical landmarks.

In addition to other areas of expertise, the perioperative nurse must be knowledgeable with anatomy, surgical techniques, instruments, OR equipment, and perioperative safety. Endotracheal tubes are inserted by the anesthesiologist or nurse anesthetist. While helping with intubation, the perioperative nurse is not responsible for locating internal anatomic markers to guarantee proper tube placement.

Question 6: Which information must be documented when a witness observes a forensic evidence collection?

Only the witness's badge number
Witness name, role, and signature (Correct answer)
Witness's supervisor's name
Witness's personal contact information

Correct answer: Witness name, role, and signature

The witness's identity, professional role, and signature confirm independent observation of the collection process.

Question 7: Which specimen provides the longest detection window for most drugs of abuse in forensic testing?

Urine
Blood
Saliva
Hair (Correct answer)

Correct answer: Hair

Hair retains drug metabolites for months, providing the longest detection window compared to other biological specimens.

Question 8: Which agency requires hospitals to report sentinel events including serious medication errors?

The Joint Commission (TJC) (Correct answer)
The Department of Labor
The Federal Trade Commission
The Drug Enforcement Administration

Correct answer: The Joint Commission (TJC)

The Joint Commission requires accredited facilities to report sentinel events and conduct root cause analyses as part of its accreditation standards.

Question 9: Which of the following sutures is not biodegradable?

Mersilene (polyester). (Correct answer)
Chromic gut.
Plain surgical gut.
Vicryl

Correct answer: Mersilene (polyester).

Mersilene is an unabsorbable polyester fiber. Absorbable sutures include Vicryl, chromic gut, and regular surgical gut.

Question 10: When a forensic pharmacy nurse prepares a written expert opinion for civil litigation, the opinion must be based on:

Only peer-reviewed studies published within the last 2 years
Absolute scientific certainty without any doubt
A reasonable degree of pharmaceutical/pharmacological certainty (Correct answer)
Personal intuition and clinical experience alone

Correct answer: A reasonable degree of pharmaceutical/pharmacological certainty

Expert opinions in civil litigation must be expressed to a 'reasonable degree of pharmaceutical certainty,' meaning more probable than not, based on sound scientific methodology.

Question 11: Graded compression stockings, often known as sequential stockings, significantly lower the prevalence of?

infection
deep vein thrombosis (DVT). (Correct answer)
pressure sores.
electrical injury.

Correct answer: deep vein thrombosis (DVT).

Deep vein thrombosis is avoided with graduated compression stockings (sometimes called sequential stockings). Proper posture prevents pressure sores from developing. Infections can be avoided with proper sanitary technique. Electrical damage can be prevented by using the right grounding methods and receiving proper instruction on how to use OR equipment. Due to the possibility of causing a pulmonary embolism, sequential stockings should not be used on the leg that is not affected by a DVT.

Question 12: What is a 'near miss' in medication safety terminology?

A medication error that caused minor harm
A prescribing error discovered after patient discharge
An error that was caught and corrected before reaching the patient (Correct answer)
An incorrect medication that was returned to the pharmacy

Correct answer: An error that was caught and corrected before reaching the patient

Near misses are caught errors that never reach the patient; they are valuable learning opportunities for system improvement.

Question 13: What is the best way to define "surgical gut"?

suture derived from the collagen of the submucosal layer of sheep, cattle, or hog intestine. (Correct answer)
suture made from nylon.
suture made from the intestines of a cat.
type of nonabsorbable suture.

Correct answer: suture derived from the collagen of the submucosal layer of sheep, cattle, or hog intestine.

The term "surgical gut" refers to suture made from submucosal layer collagen of sheep, cattle, or hog intestines. Nylon suture is non-absorbable, and the term "catgut" is a misnomer that may derive from the Arabic word kit, which meaning "dancing master's fiddle."

Question 14: Which federal statute prohibits the dispensing of prescription drugs without a valid prescription and establishes the framework distinguishing prescription from over-the-counter medications?

Controlled Substances Act of 1970
Durham-Humphrey Amendment of 1951 to the Federal Food, Drug, and Cosmetic Act (Correct answer)
OBRA '90
Drug Quality and Security Act of 2013

Correct answer: Durham-Humphrey Amendment of 1951 to the Federal Food, Drug, and Cosmetic Act

The Durham-Humphrey Amendment of 1951 established the legal distinction between prescription and OTC drugs and required a valid prescription for dispensing legend drugs.

Question 15: Which drug is commonly used as a 'date rape' drug and is associated with drug-facilitated sexual assault investigations?

Temazepam
Chlordiazepoxide
Lorazepam
Flunitrazepam (Rohypnol) (Correct answer)

Correct answer: Flunitrazepam (Rohypnol)

Flunitrazepam (Rohypnol) is notorious for use in drug-facilitated sexual assault due to its potency, amnestic effects, and rapid onset.

Question 16: A forensic pharmacy nurse is investigating a case where unusually high doses of morphine were documented but patients reported undertreated pain. Which diversion method does this suggest?

Theft of sealed unit-dose packages
Forging prescriptions for personal use
Complete substitution with saline
Skimming (removing part of the dose before administration) (Correct answer)

Correct answer: Skimming (removing part of the dose before administration)

Skimming involves administering less than the documented dose and keeping the remainder, resulting in under-controlled pain despite charted full doses.

Question 17: A forensic pharmacy nurse is reviewing a case involving a nurse anesthetist suspected of diverting propofol. What makes propofol diversion particularly dangerous and challenging to detect?

Propofol diversion always leaves clear electronic health record evidence
Propofol is water-soluble and rapidly excreted, with no standard urine test (Correct answer)
Propofol is a Schedule II controlled substance with strict DEA tracking
Propofol causes a distinctive odor easily detected in the work environment

Correct answer: Propofol is water-soluble and rapidly excreted, with no standard urine test

Propofol is not a DEA-scheduled drug, has no standard urine immunoassay test, and is rapidly metabolized, making both detection and regulatory oversight difficult.

Question 18: When is it appropriate for a forensic pharmacy nurse to release evidence directly to a patient's family member?

When the attending physician approves
When the patient gives verbal consent
When the family member presents a photo ID
Never without proper legal authorization (Correct answer)

Correct answer: Never without proper legal authorization

Forensic evidence can only be released to authorized parties such as law enforcement or legal representatives with proper documentation.

Question 19: In forensic investigation of a fatal medication error, which principle guides the analysis toward system failures rather than individual blame?

Res ipsa loquitur
Respondeat superior doctrine
Just Culture philosophy (Correct answer)
Zero tolerance policy

Correct answer: Just Culture philosophy

Just Culture distinguishes between human error, at-risk behavior, and reckless behavior to promote learning and appropriate accountability.

Question 20: Benzodiazepines are typically detectable in urine for how long after therapeutic use?

3–7 days for short-acting; up to 6 weeks for long-acting (Correct answer)
1–3 days for all types
12–24 hours for all types
1–3 months for all types

Correct answer: 3–7 days for short-acting; up to 6 weeks for long-acting

Detection windows vary significantly between short-acting and long-acting benzodiazepines based on their metabolites and half-lives.

Question 21: The main channels by which bacteria in the OR are spread are as follows:

sneezing, coughing, and talking.
blood and dirty equipment.
droplet, airborne, and contact. (Correct answer)
body fluids, purulent material, and blood.

Correct answer: droplet, airborne, and contact.

Droplet, airborne, and touch are the three methods of transmission for bacteria in the OR. The three mechanisms of transmission—sneezing, coughing, talking, and unclean equipment—include body fluids, purulent material, blood, as well as other potential sources of contamination.

Question 22: A DEA registration number for a physician begins with the letter 'A' or 'B'. What does the first letter of a DEA number typically signify?

The schedules of controlled substances authorized
The state where the physician is licensed
The year the DEA registration was issued
The type of DEA registrant (e.g., practitioner, hospital) (Correct answer)

Correct answer: The type of DEA registrant (e.g., practitioner, hospital)

The first letter of a DEA registration number indicates the type of registrant, such as 'A' or 'B' for practitioners, 'M' for mid-level practitioners, and 'P' or 'R' for distributors.

Question 23: What does 'wasting' a controlled substance mean in the hospital context, and why is it forensically significant?

Discarding unused medication with a witness, significant because fraudulent wasting is a primary diversion method (Correct answer)
Disposing of expired medications, significant for environmental compliance
Administering only part of a dose, significant for dosing accuracy
Returning unused medications to pharmacy, significant for cost savings

Correct answer: Discarding unused medication with a witness, significant because fraudulent wasting is a primary diversion method

Wasting is the witnessed disposal of unused controlled substance; falsifying waste records is a common method of concealing diversion.

Question 24: Under the Drug Supply Chain Security Act (DSCSA), which key requirement helps prevent counterfeit medications from entering the pharmaceutical supply chain?

Track-and-trace serialization of prescription drug products (Correct answer)
Random FDA inspections of retail and hospital pharmacies
Mandatory DEA drug testing of all pharmacy personnel
Mandatory electronic prescribing for all controlled substances

Correct answer: Track-and-trace serialization of prescription drug products

The DSCSA requires serialization and track-and-trace systems to verify the integrity of prescription drugs at each point in the supply chain from manufacturer to patient.

Question 25: An emergency oral prescription for a Schedule II controlled substance may be dispensed in what quantity?

Up to a 15-day supply
Only enough to cover the emergency period, typically a 72-hour supply (Correct answer)
Up to a 7-day supply
Up to a 30-day supply

Correct answer: Only enough to cover the emergency period, typically a 72-hour supply

Emergency oral prescriptions for Schedule II controlled substances may only be dispensed in a quantity sufficient for the emergency period, generally limited to a 72-hour supply.

Question 26: What is the most professionally appropriate way for a forensic pharmacy nurse to respond to a question she does not know the answer to during testimony?

Reference what a colleague would likely say
Defer to the attorneys to provide the answer
State 'I don't know' or 'I don't recall' clearly and honestly (Correct answer)
Provide her best guess to avoid appearing uninformed

Correct answer: State 'I don't know' or 'I don't recall' clearly and honestly

Honesty about the limits of knowledge is essential; guessing or speculating undermines credibility and the integrity of testimony.

Question 27: A patient who ingested a large quantity of acetaminophen 6 hours ago has a serum acetaminophen level. Which tool is used to predict hepatotoxicity risk and guide N-acetylcysteine therapy?

CIWA-Ar scale
Rumack-Matthew nomogram (Correct answer)
Naranjo algorithm
REMS nomogram

Correct answer: Rumack-Matthew nomogram

The Rumack-Matthew nomogram plots serum acetaminophen concentration against time post-ingestion to predict hepatotoxicity risk and determine NAC treatment thresholds.

Question 28: The perioperative nursing assessment on a breast biopsy patient reveals that she is crying, hence the following nursing diagnosis is most likely:

fear of medical personnel.
fear of anaphylactic reaction.
fear of missing work.
fear of body image change, pain, or death. (Correct answer)

Correct answer: fear of body image change, pain, or death.

In addition to more typical worries related to surgery and anesthesia, the preoperative patient facing a breast biopsy also faces the anxiety of a change in body image (disfigurement). Anesthesia and surgical procedures can cause anxiety due to a variety of factors, including but not limited to potential surgical outcomes, lifestyle implications, loss of control, pain, and even death.

Question 29: Which of the following is a common behavioral red flag indicating possible drug diversion by a healthcare employee?

Frequent requests to work night shifts alone near the medication room (Correct answer)
Taking scheduled breaks at regular times
Requesting reassignment to a different unit
Consistently documenting medication waste

Correct answer: Frequent requests to work night shifts alone near the medication room

Seeking unsupervised access to medication storage is a significant behavioral indicator of potential diversion.

Question 30: In a forensic medication error investigation, what does 'failure mode and effects analysis' (FMEA) proactively identify?

Documentation gaps in the medical record
The cause of a specific error that already happened
Potential failure points in a medication process before errors occur (Correct answer)
Individual staff members responsible for an error

Correct answer: Potential failure points in a medication process before errors occur

FMEA is a prospective tool that systematically identifies where a process could fail and the potential consequences before harm occurs.
