NR507 / NURSING EXAMS (CHAMBERLAIN UNIVERSITY) FINAL
EXAM| ACTUAL EXAM QUESTIONS AND CORRECT ANSWERS
WITH COMPLETE EXPLANATIONS 2026| ALREADY GRADE A+.
1. A nurse practitioner is assessing a patient with suspected heart failure.
Which biomarker is most specific for diagnosing heart failure
exacerbation?
A. Troponin I
B. B-type natriuretic peptide (BNP)
C. C-reactive protein (CRP)
D. Creatine kinase-MB (CK-MB)
Correct Answer: B
Explanation: BNP is released in response to ventricular stretch and is
highly specific for heart failure. Troponin indicates myocardial injury,
CRP indicates inflammation, and CK-MB is related to myocardial
infarction.
2. Which antihypertensive medication is contraindicated in pregnancy?
A. Labetalol
B. Methyldopa
C. Lisinopril
D. Nifedipine
Correct Answer: C
Explanation: ACE inhibitors like lisinopril are teratogenic and
contraindicated in pregnancy. Labetalol, methyldopa, and nifedipine are
considered safer alternatives.
3. A patient presents with polyuria, polydipsia, and polyphagia. Which
diagnostic test confirms diabetes mellitus?
A. Random glucose 150 mg/dL
B. Fasting glucose 110 mg/dL
C. HbA1c 6.0%
D. Fasting glucose ≥126 mg/dL
Correct Answer: D
Explanation: A fasting glucose ≥126 mg/dL confirms diabetes. The other
values fall below diagnostic thresholds.
,4. Which electrolyte imbalance is most commonly associated with cardiac
arrhythmias?
A. Hypernatremia
B. Hypokalemia
C. Hypercalcemia
D. Hypophosphatemia
Correct Answer: B
Explanation: Potassium plays a key role in cardiac conduction.
Hypokalemia can cause dangerous arrhythmias.
5. A patient taking warfarin should be monitored using which laboratory
test?
A. aPTT
B. INR
C. Platelet count
D. Hemoglobin
Correct Answer: B
Explanation: INR is used to monitor warfarin therapy. aPTT is used for
heparin.
6. Which condition is characterized by decreased TSH and increased T3/T4
levels?
A. Hypothyroidism
B. Hyperthyroidism
C. Thyroiditis
D. Goiter
Correct Answer: B
Explanation: Hyperthyroidism suppresses TSH due to negative feedback
and increases T3/T4 levels.
7. A nurse identifies Kussmaul respirations. This is most commonly
associated with:
A. Respiratory alkalosis
B. Metabolic acidosis
C. Respiratory acidosis
D. Metabolic alkalosis
Correct Answer: B
, Explanation: Kussmaul respirations are deep, rapid breaths seen in
metabolic acidosis, especially DKA.
8. Which medication is first-line for acute anaphylaxis?
A. Diphenhydramine
B. Epinephrine
C. Prednisone
D. Albuterol
Correct Answer: B
Explanation: Epinephrine is the first-line treatment for anaphylaxis due
to its rapid reversal of airway constriction and hypotension.
9. A patient with COPD should avoid which medication?
A. Albuterol
B. Ipratropium
C. Propranolol
D. Tiotropium
Correct Answer: C
Explanation: Non-selective beta-blockers like propranolol can worsen
bronchoconstriction in COPD.
10.Which lab finding is indicative of iron deficiency anemia?
A. Increased ferritin
B. Decreased TIBC
C. Increased hemoglobin
D. Decreased ferritin
Correct Answer: D
Explanation: Iron deficiency anemia presents with low ferritin and high
TIBC.
11.A patient presents with sudden unilateral weakness and slurred speech.
What is the priority action?
A. Administer aspirin
B. Check blood glucose
C. Initiate stroke protocol
D. Perform MRI
, Correct Answer: C
Explanation: Immediate stroke protocol is critical to assess eligibility for
thrombolytics.
12.Which vaccine is contraindicated in immunocompromised patients?
A. Influenza (inactivated)
B. MMR
C. Pneumococcal
D. Hepatitis B
Correct Answer: B
Explanation: MMR is a live vaccine and contraindicated in
immunocompromised patients.
13.Which medication class is most effective for reducing mortality in heart
failure?
A. Loop diuretics
B. ACE inhibitors
C. Calcium channel blockers
D. Nitrates
Correct Answer: B
Explanation: ACE inhibitors improve survival in heart failure patients.
14.What is the most common cause of community-acquired pneumonia?
A. Staphylococcus aureus
B. Streptococcus pneumoniae
C. Klebsiella pneumoniae
D. Mycoplasma pneumoniae
Correct Answer: B
Explanation: Streptococcus pneumoniae is the leading cause of
community-acquired pneumonia.
15.Which condition is associated with a “butterfly rash”?
A. Psoriasis
B. Lupus
C. Rosacea
D. Dermatitis
