2026–2027 | NCLEX-STYLE PRACTICE QUESTIONS, VERIFIED ANSWERS &
DETAILED RATIONALES STUDY GUIDE
DOCUMENT OVERVIEW
• This comprehensive study guide contains 200 verified NCLEX-style practice
questions with detailed rationales to strengthen your clinical reasoning, test-taking
strategies, and content mastery across all major nursing domains tested on the RN
ATI Capstone Proctored Exam.
• Use this material by working through questions systematically, reviewing
rationales carefully for both correct and incorrect options, timing yourself to build
speed and accuracy, and retaking questions you miss to identify knowledge gaps
before your proctored assessment.
Question 1
A 45-year-old client with chronic hypertension is prescribed lisinopril, an ACE
inhibitor. Which side effect should the nurse instruct the client to report
immediately?
A) A dry cough that develops within the first few weeks of therapy
B) Increased appetite and mild weight gain
C) Angioedema affecting the lips, tongue, or airway
D) Slightly elevated potassium levels on routine labs
E) Mild dizziness upon standing in the morning
CORRECT ANSWER: C - Angioedema affecting the lips, tongue, or airway
,Rationale: Angioedema is a serious, potentially life-threatening adverse reaction to
ACE inhibitors that requires immediate medical intervention. While a dry cough is a
common side effect that clients should expect, angioedema signals an allergic
response and can obstruct the airway. The other options are either expected
findings (dry cough, dizziness) or require monitoring but are not immediate threats
requiring urgent reporting.
Question 2
A 68-year-old male client with type 2 diabetes is receiving metformin 1000 mg
twice daily. Which assessment finding would most concern the nurse and
require holding the medication?
A) Fasting blood glucose of 145 mg/dL
B) Serum creatinine of 1.8 mg/dL indicating reduced renal function
C) Mild gastrointestinal distress reported during initial therapy
D) HbA1c of 7.2% indicating improved glycemic control
E) Slight weight loss of 3 pounds over one month
CORRECT ANSWER: B - Serum creatinine of 1.8 mg/dL indicating reduced renal
function
Rationale: Metformin is contraindicated in clients with significant renal impairment
because it increases the risk of lactic acidosis, a life-threatening condition. A serum
creatinine of 1.8 mg/dL indicates moderate to severe renal dysfunction, and the
medication should be held until renal function is reassessed. The nurse should
notify the provider. Mild GI distress is expected and often resolves; improved
HbA1c reflects therapeutic success; and mild weight loss is acceptable.
Question 3
,A 52-year-old female client undergoing chemotherapy for breast cancer
develops severe nausea and vomiting despite receiving ondansetron. Which
intervention should the nurse implement first?
A) Administer a second antiemetic medication from a different drug class
B) Ensure the client's NPO status and assess hydration and electrolyte levels
C) Notify the provider and continue current antiemetic regimen without changes
D) Provide ice chips and encourage small sips of clear liquids
E) Reposition the client and provide a calm, quiet environment
CORRECT ANSWER: B - Ensure the client's NPO status and assess hydration
and electrolyte levels
Rationale: When breakthrough nausea/vomiting occurs despite an antiemetic, the
first nursing priority is to assess for dehydration and electrolyte imbalances
(especially hypokalemia and hyponatremia), which are immediate health threats.
While environmental comfort measures and NPO status are important, assessment
of hydration status takes priority. The nurse should notify the provider, but
assessment precedes notification. Adding another antiemetic may be necessary,
but only after the provider is informed and current status is evaluated.
Question 4
A 78-year-old client with heart failure is prescribed digoxin. The nurse reviews
the client's electrolyte panel and notes a potassium level of 3.1 mEq/L. What
is the nurse's priority action?
A) Administer the scheduled digoxin dose and monitor heart rate closely
B) Hold the digoxin dose and notify the provider immediately
C) Increase dietary potassium intake and recheck levels in 24 hours
D) Give the digoxin with a potassium supplement simultaneously
E) Decrease the digoxin dose by half and reassess in 4 hours
, CORRECT ANSWER: B - Hold the digoxin dose and notify the provider
immediately
Rationale: Hypokalemia (K+ 3.1 mEq/L; normal 3.5–5.0) significantly increases the
risk of digoxin toxicity and dangerous cardiac arrhythmias. Digoxin and potassium
have an inverse relationship—low potassium increases digoxin levels in the serum.
The nurse must hold the dose and immediately notify the provider so potassium
can be repleted before continuing digoxin therapy. Administering the dose despite
low potassium places the client at immediate risk for toxicity.
Question 5
A 40-year-old client admitted to the psychiatric unit for depression and
suicidal ideation is started on sertraline, an SSRI. On day 3, the client's family
reports increased agitation, restlessness, and suicidal thoughts. What is the
nurse's most appropriate response?
A) Reassure the family that this is normal and will resolve within 1 week
B) Discontinue the medication immediately to prevent worsening
C) Notify the provider immediately; increased suicidal ideation is a black box
warning concern
D) Increase the dose to achieve faster therapeutic effect
E) Switch to a different SSRI with fewer side effects
CORRECT ANSWER: C - Notify the provider immediately; increased suicidal
ideation is a black box warning concern
Rationale: SSRIs carry an FDA black box warning for increased suicidality,
particularly in young adults and during initial therapy (first 2 weeks). Activation
syndrome (agitation, restlessness, increased suicidal thoughts) can occur early in
SSRI therapy. Although this can be temporary, increased suicidal ideation during
the first week of therapy must be reported to the provider immediately. The
medication should not be discontinued abruptly (risk of discontinuation syndrome),
