IntroductionThe purpose of this comprehensive assessment is to evaluate and predict readiness for professional nursing licensure. It
systematically assesses foundational knowledge, critical thinking, and clinical judgment across the lifespan. The evaluation utilizes standard
multiple-choice and complex scenario-based questions to replicate the rigorous environments of high-stakes licensing boards. Key areas of
focus include patient prioritization, regulatory compliance, legal-ethical boundaries, and safe medication administration. By emphasizing
real-world clinical application and evidence-based decision-making, this exam-style guide serves as a diagnostic tool to identify knowledge
gaps, reinforce nursing competencies, and ensure safe, high-quality patient care in diverse healthcare settings.
SECTION ONE
Question 1
A nurse is planning care for a client who is prescribed a continuous intravenous infusion of heparin for a deep-vein thrombosis. Which of the
following laboratory values should the nurse monitor to adjust the heparin dosage?
A. Prothrombin time (PT)
B. International Normalized Ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Platelet count
🟢 C. Activated partial thromboplastin time (aPTT)
🔴 RATIONALE: The aPTT is utilized to monitor the therapeutic effectiveness of continuous unconjugated heparin infusions. The
therapeutic range is typically 1.5 to 2.5 times the normal control value. PT and INR are used to monitor oral warfarin therapy. Platelet counts
are monitored to detect heparin-induced thrombocytopenia, but are not used to titrate the heparin dosage.
Question 2
A nurse in an emergency department is assessing a client who reports a sudden onset of severe right lower quadrant abdominal pain,
nausea, and vomiting. The client's temperature is 38.4 C (101.1 F). Which of the following interventions should the nurse anticipate
executing first?
A. Administering an intravenous opioid analgesic
B. Initiating intravenous fluid resuscitation
C. Preparing the client for an abdominal ultrasound
D. Obtaining a surgical consultation
🟢 B. Initiating intravenous fluid resuscitation
🔴 RATIONALE: Using the airway, breathing, circulation (ABC) framework, maintaining circulatory volume and stability is the priority when a
client exhibits signs of acute inflammation or potential infection/perforation (such as appendicitis). Fluid resuscitation ensures adequate
,organ perfusion before diagnostic testing or surgical intervention. Pain management and diagnostic imaging are important but follow airway
and circulatory stabilization.
Question 3
A nurse is preparing to administer regular insulin and NPH insulin in the same syringe to a client who has type 1 diabetes mellitus. Which of
the following actions should the nurse take first?
A. Draw up the NPH insulin into the syringe
B. Inject air into the regular insulin vial
C. Draw up the regular insulin into the syringe
D. Inject air into the NPH insulin vial
🟢 D. Inject air into the NPH insulin vial
🔴 RATIONALE: The correct sequence for mixing insulin is to inject air into the cloudy (NPH) vial first, without letting the needle touch the
solution, then inject air into the clear (regular) vial. Next, the nurse immediately withdraws the regular insulin, followed by withdrawing the
NPH insulin. This prevents contamination of the short-acting insulin with the intermediate-acting insulin.
Question 4
A nurse is evaluating an older adult client who was admitted with a diagnosis of dehydration. Which of the following findings is the most
reliable indicator of fluid volume status recovery in this client?
A. Moist mucous membranes
B. Increased skin turgor on the forearm
C. Stable daily weight measurements
D. Decreased serum sodium levels
🟢 C. Stable daily weight measurements
🔴 RATIONALE: Daily weight measurements taken at the same time, using the same scale, and wearing similar clothing provide the most
accurate and objective measurement of fluid volume changes. Skin turgor is unreliable in older adults due to a natural loss of skin elasticity.
Mucous membranes can be affected by mouth breathing or medications, making them less reliable than weight.
Question 5
A nurse is caring for a client who is 2 hours postoperative following a total thyroidectomy. Which of the following assessment findings
represents the highest priority risk to the client?
A. Muscle tremors and tingling around the mouth
B. Laryngeal stridor and respiratory distress
C. Pain rating of 7 on a 0-to-10 scale
D. Serosanguineous drainage on the surgical dressing
🟢 B. Laryngeal stridor and respiratory distress
🔴 RATIONALE: Airway obstruction due to edema, hemorrhage, or bilateral laryngeal nerve damage is a life-threatening complication
following a thyroidectomy. Laryngeal stridor indicates airway compromise and requires immediate emergency intervention. Muscle tremors
(hypocalcemia) are critical but subordinate to an active airway emergency.
Question 6
,A nurse is reviewing the laboratory results of a client who is receiving a continuous intravenous infusion of magnesium sulfate for
preeclampsia. The magnesium level is 9.0 mEq/L. Which of the following clinical findings should the nurse expect?
A. Hyperreflexia and tremors
B. Absence of deep tendon reflexes
C. Tachycardia and hypertension
D. Increased respiratory rate
🟢 B. Absence of deep tendon reflexes
🔴 RATIONALE: A magnesium level of 9.0 mEq/L is elevated above the therapeutic range (typically 4 to 7 mEq/L). Signs of magnesium
toxicity include diminished or absent deep tendon reflexes, bradypnea, hypotension, bradycardia, and central nervous system depression.
Question 7
A nurse is caring for a client who is in the active stage of labor and notes late decelerations on the fetal monitor strip. Which of the following
actions should the nurse perform first?
A. Administer oxygen via a nonrebreather mask
B. Increase the rate of the maintenance intravenous fluids
C. Turn the client onto her left side
D. Discontinue the oxytocin infusion
🟢 C. Turn the client onto her left side
🔴 RATIONALE: Late decelerations indicate uteroplacental insufficiency. The first action the nurse should take is to reposition the client to
her side (preferably left side) to alleviate uterine pressure on the inferior vena cava, which maximizes placental perfusion. Other
interventions like stopping oxytocin, increasing IV fluids, and applying oxygen are appropriate but occur immediately after repositioning.
Question 8
A nurse is assessing a client who has a chest tube connected to a water-seal drainage system. The nurse notes continuous bubbling in the
water-seal chamber. How should the nurse interpret this finding?
A. The system is operating normally
B. There is an active air leak in the system
C. The suction pressure is set too high
D. The client's lung has fully re-expanded
🟢 B. There is an active air leak in the system
🔴 RATIONALE: Continuous bubbling in the water-seal chamber indicates an air leak within the system or at the insertion site. Intermittent
bubbling is expected during expiration or coughing when air exits the pleural space. Continuous bubbling requires systematic checking of
the connections to locate and correct the leak.
Question 9
A charge nurse is observing a newly licensed nurse perform tracheostomy care for a client. Which of the following actions by the newly
licensed nurse requires intervention?
A. Cleaning the inner cannula with sterile normal saline
B. Applying a non-split gauze dressing under the tracheostomy flange
, C. Cutting a standard sterile gauze pad to fit around the tracheostomy tube
D. Securing new tracheostomy ties before removing the old ones
🟢 C. Cutting a standard sterile gauze pad to fit around the tracheostomy tube
🔴 RATIONALE: Cutting standard gauze pads is prohibited because loose fibers or threads from the cut edges can be aspirated into the
trachea, causing infection or irritation. Specially manufactured pre-split tracheostomy dressings should be utilized instead.
Question 10
A nurse is preparing to administer an intramuscular injection to an infant who is 6 months old. Which of the following anatomical sites should
the nurse select?
A. Dorsogluteal
B. Ventrogluteal
C. Vastus lateralis
D. Deltoid
🟢 C. Vastus lateralis
🔴 RATIONALE: The vastus lateralis muscle is the preferred and safest site for intramuscular injections in infants under 12 months of age
because it is the most developed muscle mass and avoids major nerves and blood vessels.
Question 11
A nurse is reinforcing teaching with a client who has a new prescription for sublingual nitroglycerin tablets for the management of angina
pectoris. Which of the following instructions should the nurse include?
A. Swallow the tablet with a full glass of water if pain persists
B. Take up to 5 tablets at 10-minute intervals for chest pain
C. Place one tablet under the tongue at the onset of chest pain
D. Store the medication in a clear plastic container in the refrigerator
🟢 C. Place one tablet under the tongue at the onset of chest pain
🔴 RATIONALE: Sublingual nitroglycerin must be placed under the tongue at the immediate onset of chest pain. It should not be swallowed.
The client can take one tablet every 5 minutes for a maximum of 3 doses; if pain does not improve or worsens after the first dose,
emergency services should be called. The medication must be stored in its original dark glass vial to prevent degradation from light and
moisture.
Question 12
A nurse is assessing a client who is 12 hours postoperative following an abdominal hysterectomy. Which of the following findings should the
nurse report to the provider immediately?
A. Urinary output of 20 mL/hr over the past 2 hours
B. Serosanguineous drainage on the abdominal dressing
C. Decreased bowel sounds in all four quadrants
D. White blood cell count of 11,000/mm³
