Comprehensive NCLEX Review
Question 1: A nurse is caring for a client who is receiving a
continuous IV infusion of heparin. Which laboratory value should
the nurse monitor to evaluate the therapeutic effect of this
medication?
A. Prothrombin time (PT)
B. International Normalized Ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Bleeding time
CORRECT ANSWER: C. Activated partial thromboplastin time
(aPTT)
Rationale: The activated partial thromboplastin time (aPTT) is the standard
laboratory test used to monitor the therapeutic effect of unfractionated
heparin. The therapeutic range for aPTT is typically 1.5 to 2.5 times the
control value. PT and INR are used to monitor warfarin therapy, not
heparin. Bleeding time assesses platelet function and primary hemostasis,
not the intrinsic coagulation pathway affected by heparin .
Question 2: A client with chronic kidney disease has a serum
potassium level of 6.2 mEq/L. Which electrocardiogram (ECG)
change should the nurse expect to observe?
A. Prominent U waves
B. ST segment depression
C. Tall, peaked T waves
D. Prolonged QT interval
CORRECT ANSWER: C. Tall, peaked T waves
Rationale: Hyperkalemia, defined as a serum potassium level greater than
5.0 mEq/L, causes characteristic ECG changes including tall, peaked T
,waves. As hyperkalemia worsens, the QRS complex may widen and the P
wave may flatten or disappear. Prominent U waves are associated with
hypokalemia. ST segment depression can occur with hypokalemia or
myocardial ischemia .
Question 3: A nurse is preparing to administer a medication that is
highly protein-bound. The client has hypoalbuminemia. Which
effect should the nurse anticipate?
A. Decreased pharmacological effect of the medication
B. Increased free drug concentration and risk of toxicity
C. Rapid renal excretion of the medication
D. No change in drug response
CORRECT ANSWER: B. Increased free drug concentration and risk
of toxicity
Rationale: When a medication is highly protein-bound, it attaches to
albumin in the bloodstream. In hypoalbuminemia, there are fewer binding
sites available, resulting in an increased concentration of free (unbound)
drug. Only the free drug is pharmacologically active, so this increases both
the therapeutic effect and the risk of adverse effects or toxicity .
Question 4: A client is prescribed oral morphine for chronic pain
but reports inadequate relief. The nurse explains that a significant
portion of the drug is inactivated before reaching systemic
circulation. Which phenomenon accounts for this?
A. Protein binding
B. First-pass effect
C. Blood-brain barrier
D. Renal clearance
CORRECT ANSWER: B. First-pass effect
Rationale: The first-pass effect occurs when orally administered
medications are absorbed through the gastrointestinal tract and transported
via the portal vein to the liver, where a significant portion is metabolized
before entering systemic circulation. This reduces bioavailability and is why
some medications require higher oral doses or alternative routes. Protein
binding affects drug distribution, not initial metabolism. The blood-brain
barrier limits drug entry into the central nervous system .
,Question 5: A nurse is caring for a client who experienced a
needlestick injury from a used hollow-bore needle. What is the
nurse's first action?
A. Report the incident to the supervisor
B. Complete an incident report
C. Wash the site with soap and water
D. Obtain the source client's medical history
CORRECT ANSWER: C. Wash the site with soap and water
Rationale: The immediate priority after a needlestick injury is to wash the
exposed area thoroughly with soap and water to reduce the risk of
transmission of bloodborne pathogens. After immediate first aid, the nurse
should report the exposure according to occupational health protocol for
risk assessment, source testing, and possible post-exposure prophylaxis.
Documentation and incident reporting follow the initial washing .
Question 6: A client with Clostridioides difficile infection requires
care. Which hand hygiene method should the nurse use after
providing care?
A. Alcohol-based hand rub
B. Soap and water
C. Iodine-based surgical scrub
D. No hand hygiene is required if gloves were worn
CORRECT ANSWER: B. Soap and water
Rationale: Clostridioides difficile spores are not reliably killed by alcohol-
based hand rubs. The mechanical action of washing with soap and water is
required to physically remove the spores from the hands. Contact
precautions are also indicated, and environmental cleaning with a
sporicidal agent is necessary. Wearing gloves does not eliminate the need
for hand hygiene after glove removal .
Question 7: A nurse is caring for a client with suspected pulmonary
tuberculosis. Which personal protective equipment should the
nurse wear when entering the client's room?
A. Surgical mask
B. Fit-tested N95 respirator
, C. Face shield only
D. Gown and gloves only
CORRECT ANSWER: B. Fit-tested N95 respirator
Rationale: Tuberculosis is transmitted via airborne particles, requiring
airborne precautions. A fit-tested N95 respirator or equivalent is required to
filter out infectious airborne particles. A standard surgical mask does not
provide adequate protection against airborne transmission. Gown and
gloves are not sufficient without respiratory protection for airborne
precautions .
Question 8: A nurse is preparing to administer medications. Which
action best promotes medication safety?
A. Administering medications from memory
B. Leaving prepared medications at the bedside for later administration
C. Using at least two client identifiers before administration
D. Asking another client to identify the medication recipient
CORRECT ANSWER: C. Using at least two client identifiers before
administration
Rationale: Using at least two approved client identifiers (such as name and
date of birth) before medication administration is a critical safety practice
that prevents wrong-client errors. Administering from memory bypasses
safety verification. Leaving medications unattended can lead to
administration errors. Asking another client to identify the recipient is
unsafe and violates confidentiality .
Question 9: A client begins having a generalized tonic-clonic
seizure while in bed. What is the nurse's priority action?
A. Restrain the client's extremities
B. Insert a tongue blade into the mouth
C. Protect the client from injury and maintain the airway
D. Administer oral medication immediately
CORRECT ANSWER: C. Protect the client from injury and maintain
the airway
Rationale: During a seizure, the priority is to protect the client from injury
by lowering the bed, removing nearby objects, and padding the side rails.
The nurse should turn the client to the side to maintain a patent airway and
