ATI PN Pharmacology Proctored 200 MOST TESTED QUESTIONS
A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the
following laboratory tests should the nurse review prior to administration?
a. Partial thromboplastin time (PTT)
b. Total iron-binding capacity
c. White blood cell count
d. Prothrombin time (PT)
✔️ Correct Answer: D
Rationale:
Prothrombin time (PT) is the appropriate laboratory test to monitor prior to warfarin
administration (Option D). Warfarin is an anticoagulant that prolongs PT by inhibiting
vitamin K-dependent clotting factors (II, VII, IX, X). The International Normalized Ratio
(INR) is calculated from PT and is used to standardize results across laboratories. The
therapeutic INR range for most indications is 2.0 to 3.0.
Option A is incorrect because PTT monitors heparin therapy, not warfarin. Option B is
incorrect because total iron-binding capacity assesses iron status. Option C is incorrect
because white blood cell count evaluates infection or immune response.
,A nurse is caring for a group of clients. Which of the following situations requires an
incident report?
a. A client experiences a seizure
b. A client vomits after receiving an oral medication
c. A client receives their insulin 1 hour before scheduled
d. A client receives their meal tray 20 minutes late
✔️ Correct Answer: C
Rationale:
An incident report should be completed when a medication is administered at the
wrong time (Option C). Administering insulin 1 hour before the scheduled time
constitutes a medication administration error that must be documented through the
incident reporting system. This deviation from the prescribed schedule could result in
hypoglycemia and requires evaluation to prevent recurrence.
Option A is incorrect because a seizure is a clinical event that should be documented in
the medical record but does not necessarily require an incident report unless it results
from an error. Option B is incorrect because vomiting after oral medication is a client
response, not a system error requiring an incident report. Option D is incorrect because
a 20-minute delay in meal delivery is a service issue that should be addressed but
typically does not warrant an incident report.
A nurse is assessing a client who has received oxycodone. The nurse notes that the
client's respiratory rate is 8 breaths per minute. The nurse should identify that which of
the following is the pathophysiology for the client's respiratory rate?
a. Oxycodone blocks the sodium channel, suspending nerve conduction
b. Oxycodone promotes vasodilation of cranial arteries
c. Oxycodone causes central nervous system depression
d. Oxycodone inhibits prostaglandin synthesis
✔️ Correct Answer: C
Rationale:
Oxycodone causes central nervous system depression (Option C), which is the
pathophysiological mechanism for the client's decreased respiratory rate of 8 breaths
per minute. Opioids bind to mu receptors in the brainstem, particularly in the medullary
respiratory center, suppressing the respiratory drive. This CNS depression results in
decreased respiratory rate and depth, which can be life-threatening.
, Option A is incorrect because sodium channel blockade is the mechanism of action for
local anesthetics and some antiarrhythmics, not opioids. Option B is incorrect because
vasodilation of cranial arteries is the mechanism for some antimigraine medications.
Option D is incorrect because prostaglandin synthesis inhibition is the mechanism for
NSAIDs, not opioids.
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via
intermittent IV bolus over 30 minutes. The drop factor of the manual IV tubing is 15
gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
(Round the answer to the nearest whole number.)
✔️ Correct Answer: 50 gtt/min
Rationale:
To calculate the IV flow rate in drops per minute (gtt/min), the nurse must divide the
total volume (100 mL) by the total time in minutes (30 minutes) and multiply by the
drop factor (15 gtt/mL). The calculation is as follows: (100 mL ÷ 30 minutes) × 15 gtt/mL
= 3.33 mL/min × 15 = 50 gtt/min. The nurse should set the manual IV infusion to deliver
50 gtt/min.
A nurse is preparing to transcribe a prescription for a client that reads "ondansetron 8
mg by mouth every 12 hr PRN." Which of the following parts of the prescription should
the nurse clarify with the provider?
a. Dose
b. Route
c. Frequency
d. Reason
✔️ Correct Answer: D
Rationale:
The "reason" for the PRN (as needed) prescription should be clarified with the provider
(Option D). A complete PRN prescription must include the specific indication for
administration. Without a clear reason, the nurse cannot appropriately assess whether
the medication should be given. The prescription should specify what symptoms warrant
administration, such as "PRN nausea" or "PRN vomiting."
