*Introduction*
*The purpose of this exam is to assess the clinical competency, critical thinking skills, and
theoretical knowledge essential for professional nursing practice. The assessment evaluates
a candidate’s ability to apply foundational nursing concepts to real-world healthcare
scenarios, ensuring safe and effective patient care. Utilizing a rigorous multiple-choice and
scenario-based structure, the exam emphasizes clinical judgment, decision-making, and
adherence to legal and ethical standards. Candidates must demonstrate proficiency in
prioritizing care, interpreting diagnostic data, and managing complex patient needs. This
evaluation serves as a comprehensive measurement of readiness for entry-level nursing
practice and professional healthcare delivery.*
SECTION ONE: QUESTIONS 1–100
1. A nurse is caring for a client with hyperkalemia. Which assessment finding should the
nurse prioritize? A. Muscle cramps B. Irregular heart rate C. Generalized weakness D.
Abdominal cramping
B. Irregular heart rate Explanation: Hyperkalemia significantly affects cardiac
electrical conduction, making cardiac arrhythmias the most life-threatening complication
that requires immediate intervention.
, 2. A nurse is preparing to administer digoxin to a client with heart failure. What is the
priority nursing action? A. Check the serum potassium level B. Assess the apical pulse
for one full minute C. Ensure the client has taken their diuretic D. Monitor the client
for visual disturbances
B. Assess the apical pulse for one full minute Explanation: Digoxin slows the heart
rate; therefore, the nurse must verify the apical pulse is within safe limits (usually above 60
bpm) before administration to prevent toxicity.
3. Which finding in a newborn indicates a need for further evaluation by the healthcare
provider? A. Acrocyanosis B. Grunting on expiration C. Presence of Epstein pearls D.
Molding of the head
B. Grunting on expiration Explanation: Grunting is a sign of respiratory distress in a
newborn and necessitates immediate clinical assessment to prevent further complications.
4. A client reports severe pain in the right lower quadrant with rebound tenderness.
Which condition should the nurse suspect? A. Cholecystitis B. Appendicitis C.
Diverticulitis D. Pancreatitis
B. Appendicitis Explanation: Right lower quadrant pain accompanied by rebound
tenderness (McBurney’s point) is a classic clinical manifestation of appendicitis.
5. A nurse is educating a client on the use of warfarin. Which food item should the
client be instructed to limit? A. Bananas B. Green leafy vegetables C. Whole grains D.
Citrus fruits
B. Green leafy vegetables Explanation: Green leafy vegetables are high in Vitamin K,
which is the antidote to warfarin; consistent or excessive intake can decrease the
effectiveness of the anticoagulant.
6. Which stage of Erikson’s psychosocial development is the toddler in? A. Trust vs.
Mistrust B. Autonomy vs. Shame and Doubt C. Initiative vs. Guilt D. Industry vs.
Inferiority
B. Autonomy vs. Shame and Doubt Explanation: According to Erikson, toddlers (ages
1-3) are in the Autonomy vs. Shame and Doubt stage, where they begin to assert their
independence.
7. A client with type 1 diabetes is found unconscious and diaphoretic. What is the
nurse's priority action? A. Administer subcutaneous insulin B. Check the client’s
capillary blood glucose C. Provide a glass of orange juice D. Notify the primary
healthcare provider
, B. Check the client’s capillary blood glucose Explanation: The nurse must first
confirm the hypoglycemic state before initiating treatment, as other conditions can mimic
these symptoms.
8. A nurse is caring for a client with a chest tube. The nurse notes continuous bubbling
in the water seal chamber. What does this indicate? A. Normal lung re-expansion B. A
leak in the chest tube system C. The need for increased suction D. Proper drainage of
pleural fluid
B. A leak in the chest tube system Explanation: Continuous bubbling in the water
seal chamber suggests air is entering the system from an external source, indicating a leak.
9. When assessing a client with fluid volume excess, which finding is expected? A.
Decreased blood pressure B. Distended neck veins C. Dry mucous membranes D.
Concentrated urine
B. Distended neck veins Explanation: Fluid volume excess leads to increased venous
pressure, which frequently manifests as jugular vein distension.
10. A client is prescribed phenytoin for seizure control. Which patient education is most
important? A. Take the medication on an empty stomach B. Maintain meticulous oral
hygiene C. Limit intake of protein-rich foods D. Expect dark-colored urine
B. Maintain meticulous oral hygiene Explanation: Phenytoin is known to cause
gingival hyperplasia; frequent dental visits and good oral hygiene are required to mitigate
this side effect.
11. Which acid-base imbalance would the nurse expect in a client with prolonged
vomiting? A. Metabolic acidosis B. Metabolic alkalosis C. Respiratory acidosis D.
Respiratory alkalosis
B. Metabolic alkalosis Explanation: Prolonged vomiting causes a loss of hydrochloric
acid from the stomach, leading to a rise in serum pH and metabolic alkalosis.
12. A nurse is caring for a client with a history of hypertension. Which medication class is
typically first-line? A. Beta-blockers B. ACE inhibitors C. Calcium channel blockers D.
Loop diuretics
B. ACE inhibitors Explanation: ACE inhibitors are frequently the first-line treatment
for hypertension due to their efficacy in reducing systemic vascular resistance and protecting
the kidneys.
13. What is the primary purpose of an incentive spirometer? A. To measure vital capacity
B. To prevent atelectasis C. To reduce oxygen demand D. To deliver aerosolized
medication
, B. To prevent atelectasis Explanation: Incentive spirometry encourages deep
breathing, which helps expand alveoli and prevents the collapse of lung tissue (atelectasis)
post-operatively.
14. A nurse is teaching a client about the DASH diet. Which nutrient should be
restricted? A. Potassium B. Calcium C. Sodium D. Magnesium
C. Sodium Explanation: The DASH (Dietary Approaches to Stop Hypertension) diet
emphasizes the restriction of sodium to lower blood pressure.
15. In a client with meningitis, which isolation precaution is required? A. Contact B.
Airborne C. Droplet D. Standard only
C. Droplet Explanation: Meningitis caused by organisms like Neisseria meningitidis is
transmitted through large droplets; therefore, droplet precautions are necessary.
16. Which of the following is a sign of lithium toxicity? A. Polyuria B. Coarse hand
tremors C. Mild nausea D. Weight gain
B. Coarse hand tremors Explanation: While fine tremors are a common side effect of
lithium, coarse tremors are a classic indicator of lithium toxicity and require immediate
clinical attention.
17. A nurse identifies a pressure ulcer on a client’s sacrum that shows full-thickness skin
loss. How is this staged? A. Stage 1 B. Stage 2 C. Stage 3 D. Stage 4
C. Stage 3 Explanation: A Stage 3 pressure ulcer involves full-thickness skin loss with
damage to or necrosis of subcutaneous tissue.
18. A client is receiving a blood transfusion and develops chills and fever. What is the
priority action? A. Slow the infusion rate B. Stop the transfusion immediately C.
Administer an antihistamine D. Document the finding in the chart
B. Stop the transfusion immediately Explanation: Chills and fever during a
transfusion are signs of a febrile non-hemolytic or hemolytic reaction; the infusion must be
stopped immediately to prevent further harm.
19. Which assessment is priority for a client following a thyroidectomy? A. Assessing the
ability to swallow B. Checking for Chvostek’s sign C. Monitoring for tachycardia D.
Evaluating vocal quality
B. Checking for Chvostek’s sign Explanation: Thyroidectomy carries a risk of
accidental removal of the parathyroid glands, which leads to hypocalcemia; Chvostek’s sign
assesses for tetany secondary to low calcium.
20. A nurse is planning care for a client with dementia. What is the best strategy? A.
Confront the client when they are confused B. Provide a consistent, structured
