North American Pharmacist Licensure Examination (NAPLEX) Pharmacy Practice, Law, and Patient Care flashcards — 59 questions with answers
What is the normal reference range for serum potassium, and what ECG change signals dangerous hyperkalemia?
Normal serum potassium is $3.5\text{–}5.0\ \text{mEq/L}$. Hyperkalemia ($>5.0$) classically produces peaked T waves and can progress to widened QRS and arrhythmia.
What is the normal serum sodium range, and what defines hyponatremia vs hypernatremia?
Normal serum sodium is $135\text{–}145\ \text{mEq/L}$. Hyponatremia is $<135\ \text{mEq/L}$; hypernatremia is $>145\ \text{mEq/L}$.
How is the corrected calcium calculated for hypoalbuminemia?
$$\text{Corrected Ca} = \text{measured Ca} + 0.8 \times (4.0 - \text{albumin})$$ where albumin is in g/dL and calcium in mg/dL. Add $0.8\ \text{mg/dL}$ per $1\ \text{g/dL}$ albumin below $4$.
What is the Cockcroft-Gault equation for estimating creatinine clearance?
$$CrCl = \frac{(140 - \text{age}) \times \text{weight (kg)}}{72 \times S_{cr}} \times (0.85\ \text{if female})$$ with $S_{cr}$ in mg/dL; result in mL/min.
What HbA1c value defines diabetes, and what is the approximate estimated average glucose for an $\text{HbA1c}$ of 7%?
Diabetes is diagnosed at $\text{HbA1c} \geq 6.5\%$. An $\text{HbA1c}$ of $7\%$ corresponds to an estimated average glucose of about $154\ \text{mg/dL}$ (each $1\%$ rise $\approx 28\text{–}29\ \text{mg/dL}$).
Which lab values are used to assess hepatic synthetic function versus hepatocellular injury?
Synthetic function: albumin, INR/PT, and bilirubin. Hepatocellular injury: ALT and AST (transaminases). Cholestasis: alkaline phosphatase and GGT.
What INR range is therapeutic for most warfarin indications, and what range applies to mechanical mitral valves?
Most indications (AFib, VTE) target $\text{INR}\ 2.0\text{–}3.0$. Mechanical mitral valves target a higher $\text{INR}\ 2.5\text{–}3.5$.
List the components of a normal adult vital sign set (temperature, HR, RR, BP, $\text{SpO}_2$).
Temperature $\approx 37^{\circ}\text{C}$ ($98.6^{\circ}\text{F}$); heart rate $60\text{–}100\ \text{bpm}$; respiratory rate $12\text{–}20/\text{min}$; blood pressure $<120/80\ \text{mmHg}$; $\text{SpO}_2 \geq 95\%$.
How do the 2017 ACC/AHA guidelines define Stage 1 and Stage 2 hypertension?
Stage 1: systolic $130\text{–}139$ or diastolic $80\text{–}89\ \text{mmHg}$. Stage 2: systolic $\geq 140$ or diastolic $\geq 90\ \text{mmHg}$.
What are the classic signs and symptoms of digoxin toxicity?
Nausea, vomiting, anorexia, confusion, visual disturbances (yellow-green halos/xanthopsia), bradycardia, and arrhythmias. Risk increases with hypokalemia and renal impairment.
What are the key elements obtained during medication reconciliation?
A complete list of all current medications (prescription, OTC, herbals, supplements) with drug name, dose, route, frequency, and indication, then comparing against new orders to resolve discrepancies (omissions, duplications, interactions) at transitions of care.
During medication history taking, what does the mnemonic 'best possible medication history' (BPMH) require beyond the med list?
It requires verifying actual use (adherence vs prescribed), last dose taken, allergies and reactions, and using two or more reliable sources (patient interview plus pharmacy records or pill bottles).
What are the four prime questions used in patient counseling (Indian Health Service method)?
1) What did the doctor tell you the medication is for? 2) How did the doctor tell you to take it? 3) What did the doctor tell you to expect? Plus the 'show-and-tell' final verification check (teach-back).
What is the 'teach-back' method and why is it used in counseling?
Teach-back asks the patient to restate or demonstrate instructions in their own words to confirm understanding. It verifies comprehension rather than simply asking 'Do you understand?' and reduces errors and improves adherence.
How is medication adherence quantified by the Proportion of Days Covered (PDC), and what threshold is generally considered adherent?
$$PDC = \frac{\text{days covered by medication supply}}{\text{days in measurement period}} \times 100\%$$ A $PDC \geq 80\%$ is generally considered adherent.
Name evidence-based strategies to improve medication adherence.
Simplifying regimens (once-daily dosing, fixed-dose combinations), using pillboxes/blister packs, reminder systems, motivational interviewing, addressing cost/access, synchronizing refills, and follow-up via MTM or telephone calls.
Under the Controlled Substances Act, what characterizes a Schedule I drug?
Schedule I drugs have a high potential for abuse, NO currently accepted medical use in the U.S., and lack accepted safety for use under medical supervision (e.g., heroin, LSD, marijuana federally).
Compare the abuse potential and refill rules for Schedule II versus Schedule III–IV controlled substances.
Schedule II: high abuse potential, NO refills allowed, new prescription required each time. Schedule III–IV: lower abuse potential, may be refilled up to 5 times within 6 months.
How long is a Schedule III, IV, or V prescription valid, and how many refills are permitted?
Schedule III and IV prescriptions are valid for 6 months from the date written and may be refilled up to 5 times within that period. Schedule V follows state-specific rules but federally allows refills as authorized.
What DEA form is required for ordering Schedule II controlled substances, and how is theft/loss reported?
Schedule II ordering requires DEA Form 222 (or its electronic CSOS equivalent). Theft or significant loss is reported using DEA Form 106.

What is the check-digit method for verifying a DEA number?
Add the 1st, 3rd, and 5th digits; add the 2nd, 4th, and 6th digits and multiply by 2; sum these two results. The last digit of that sum must equal the 7th (check) digit of the DEA number.
What are the required elements of a valid controlled substance prescription?
Patient name and address, date issued, drug name/strength/dosage form, quantity, directions for use, prescriber name/address/DEA number, and prescriber's manual or valid electronic signature. It must be for a legitimate medical purpose.
Under federal rules, when may a Schedule II prescription be partially filled, and what is the time limit to complete it?
A Schedule II prescription may be partially filled if the full quantity is unavailable; the remaining portion must be supplied within 72 hours. For LTCF or terminally ill patients, partial fills are allowed for up to 60 days.
What is the federal limit on pseudoephedrine sales under the Combat Methamphetamine Epidemic Act?
$3.6\ \text{g}$ per day and $9\ \text{g}$ per 30 days per purchaser, with a logbook (name, address, signature) and photo ID required, kept behind the counter.
What did the Federal Food, Drug, and Cosmetic Act (FDCA) of 1938 establish?
It required premarket proof of drug SAFETY before marketing (prompted by the sulfanilamide elixir disaster) and gave the FDA authority over drug labeling and adulteration/misbranding.
What did the 1962 Kefauver-Harris Amendment add to the FDCA?
It required proof of EFFICACY (not just safety) via adequate and well-controlled studies before marketing, and required adverse event reporting, prompted by the thalidomide tragedy.
What does HIPAA's Privacy Rule define as Protected Health Information (PHI), and what is the 'minimum necessary' standard?
PHI is individually identifiable health information held or transmitted by a covered entity. The minimum necessary standard requires limiting use, disclosure, and requests of PHI to the least amount needed to accomplish the purpose.
What does OBRA-90 require of pharmacists?
The Omnibus Budget Reconciliation Act of 1990 requires prospective drug utilization review (DUR), an offer to counsel Medicaid patients, and maintenance of patient records, before dispensing.
What is the difference between a covered entity and a business associate under HIPAA?
A covered entity is a health plan, healthcare clearinghouse, or provider who transmits health information electronically. A business associate performs services on the covered entity's behalf involving PHI and must sign a Business Associate Agreement.
Define a pharmacist's 'standard of care' and 'corresponding responsibility' for controlled substances.
Standard of care is the degree of skill and diligence a reasonably prudent pharmacist would exercise. Corresponding responsibility means the pharmacist shares legal duty with the prescriber to ensure a controlled substance prescription is issued for a legitimate medical purpose.
What is the difference between collaborative practice agreements (CPAs) and independent pharmacist prescriptive authority?
A CPA delegates defined clinical functions (initiate, modify, or monitor therapy) to a pharmacist under a physician's protocol. Independent authority (varies by state) allows pharmacists to prescribe certain products like naloxone, contraceptives, or immunizations via statewide protocol without a specific physician agreement.
What are the 'five rights' of medication administration used in error prevention?
Right patient, right drug, right dose, right route, and right time. Some frameworks add right documentation, right reason, and right response.
What is a key system-level strategy to prevent medication errors using forcing functions?
A forcing function physically prevents an error from occurring (e.g., tubing connectors that don't fit the wrong port, removing concentrated KCl from floor stock, barcode scanning that won't proceed on a mismatch).
Rank the medication-error prevention strategies from most to least effective in the hierarchy of controls.
Most effective: forcing functions and constraints, then automation/computerization, then standardization/protocols, then reminders/checklists, then education/information. Least effective relies on human vigilance alone.
What are look-alike/sound-alike (LASA) drugs, and give a classic example pair.
LASA drugs have names that look or sound similar, risking mix-ups. Examples: hydroxyzine/hydralazine, vinblastine/vincristine, metFORMIN/metRONIDAZOLE, and DOPamine/DOBUTamine.
What is tall man lettering and how does it reduce errors?
Tall man lettering uses mixed-case letters to highlight the differing portions of LASA drug names (e.g., predniSONE vs prednisoLONE), making visual differences more salient to reduce selection errors.
What are the five steps of a root cause analysis (RCA)?
1) Identify and form a team after an event, 2) gather data and reconstruct the timeline, 3) identify contributing factors and the root cause(s) by asking 'why' repeatedly, 4) develop and implement corrective actions, 5) measure and monitor effectiveness.
What is the difference between a sentinel event, an adverse drug event, and a near miss?
A sentinel event causes death or serious harm and triggers mandatory review. An adverse drug event is harm from a medication. A near miss (close call) is an error caught before reaching the patient or before causing harm.
What is the PDSA cycle in continuous quality improvement?
Plan (define objective and change), Do (test the change on a small scale), Study (analyze results against predictions), Act (adopt, adapt, or abandon). It is iterated rapidly for continuous improvement.
What is the difference between common-cause and special-cause variation in CQI?
Common-cause variation is inherent random fluctuation within a stable process. Special-cause variation arises from a specific, identifiable, non-random source and signals the process is out of control, requiring investigation.
Define pharmacovigilance and the purpose of post-marketing (Phase IV) surveillance.
Pharmacovigilance is the science of detecting, assessing, and preventing adverse drug effects. Phase IV surveillance monitors approved drugs in real-world use to detect rare, long-term, or population-specific adverse events not seen in trials.
What is the FDA MedWatch program, and is reporting mandatory for pharmacists?
MedWatch is the FDA's voluntary reporting system for adverse events, product problems, and medication errors. Reporting is voluntary for healthcare professionals but mandatory for manufacturers.
Rank these study designs by strength of evidence: case report, cohort study, randomized controlled trial, systematic review/meta-analysis.
From strongest to weakest: systematic review/meta-analysis of RCTs > randomized controlled trial > cohort study > case-control study > case series/case report > expert opinion.
What distinguishes a cohort study from a case-control study in direction and outcome measure?
A cohort study follows exposed vs unexposed forward in time and yields relative risk (incidence). A case-control study starts with diseased vs non-diseased and looks backward at exposure, yielding an odds ratio.
What does a p-value represent, and what does $p < 0.05$ conventionally indicate?
The p-value is the probability of observing results as extreme as those obtained if the null hypothesis were true. $p < 0.05$ means there is less than a $5\%$ chance the result is due to random chance, conventionally deemed statistically significant.
How do you interpret a 95% confidence interval for a relative risk or odds ratio?
If the $95\%$ CI for a ratio (RR or OR) crosses $1.0$, the result is not statistically significant. For a difference in means, significance is lost if the CI crosses $0$.
Which statistical test is appropriate for comparing means of two independent groups versus three or more groups?
Two independent group means: independent (unpaired) Student's t-test. Three or more group means: ANOVA. Paired/repeated measurements on the same subjects: paired t-test.
Define Type I and Type II errors in hypothesis testing.
Type I error ($\alpha$): rejecting a true null hypothesis (false positive). Type II error ($\beta$): failing to reject a false null hypothesis (false negative). Power $= 1 - \beta$.
How are absolute risk reduction (ARR) and number needed to treat (NNT) calculated?
$$ARR = \text{control event rate} - \text{treatment event rate}$$ $$NNT = \frac{1}{ARR}$$ NNT is rounded up to the next whole number; lower NNT means greater treatment benefit.
How is relative risk (RR) calculated and interpreted?
$$RR = \frac{\text{incidence in exposed}}{\text{incidence in unexposed}}$$ $RR = 1$ means no effect, $RR > 1$ indicates increased risk, and $RR < 1$ indicates a protective effect. Relative risk reduction $= 1 - RR$.
What is the difference between relative risk reduction and absolute risk reduction, and why does it matter?
Relative risk reduction expresses the proportional decrease and can appear large even when baseline risk is small. Absolute risk reduction reflects the actual difference in event rates, giving a truer sense of clinical benefit (e.g., $50\%$ RRR from $2\%$ to $1\%$ is only $1\%$ ARR, $NNT=100$).
In critical appraisal, what does intention-to-treat (ITT) analysis mean and why is it preferred?
ITT analyzes participants in the groups to which they were randomized regardless of adherence or dropout. It preserves randomization, prevents bias, and gives a conservative, real-world estimate of effect, unlike per-protocol analysis.
What is the difference between statistical significance and clinical significance?
Statistical significance ($p<0.05$) indicates a result is unlikely due to chance, but with large samples even trivial effects can be significant. Clinical significance asks whether the effect size is large enough to meaningfully change patient care.
According to the CDC adult immunization schedule, who should receive the herpes zoster (Shingrix) and pneumococcal vaccines?
Recombinant zoster (Shingrix) is recommended as 2 doses for adults $\geq 50$ years. Pneumococcal vaccination (PCV15/PCV20/PCV23) is recommended for all adults $\geq 65$ years and younger adults with risk conditions.
What are the standard intramuscular injection sites and needle considerations for adult vaccine administration?
Adult IM vaccines are given in the deltoid using a $22\text{–}25$ gauge, $1\text{–}1.5$ inch needle at a $90^{\circ}$ angle. Subcutaneous vaccines (e.g., MMR, varicella) use a $23\text{–}25$ gauge $5/8$ inch needle at a $45^{\circ}$ angle in the upper arm fat.
What is the recommended childhood DTaP and MMR vaccination schedule timing?
DTaP is given at 2, 4, 6, and 15–18 months and 4–6 years (5 doses). MMR is given at 12–15 months and 4–6 years (2 doses).
What are the 5 A's framework for smoking cessation counseling?
Ask (about tobacco use), Advise (to quit), Assess (willingness to quit), Assist (with a quit plan/pharmacotherapy), and Arrange (follow-up). For unwilling patients, the 5 R's (Relevance, Risks, Rewards, Roadblocks, Repetition) are used.
Which first-line pharmacotherapies are used for smoking cessation, and what is a key contraindication of bupropion?
First-line: nicotine replacement therapy (patch, gum, lozenge), varenicline (Chantix), and bupropion SR. Bupropion is contraindicated in patients with seizure disorders or eating disorders due to lowered seizure threshold.
What validated screening tools are used for alcohol and substance use, and what does a positive CAGE score suggest?
AUDIT and CAGE screen for alcohol use; DAST and the single-item NIDA screen for drugs. A CAGE score $\geq 2$ (out of 4: Cut down, Annoyed, Guilty, Eye-opener) suggests problematic drinking warranting further assessment.
