Question 1: A nurse is caring for a client with heart failure who has developed sudden onset
of dyspnea, tachycardia, and crackles in both lung fields. Which action should the nurse
prioritize first?
A. Administer the prescribed furosemide IV push
B. Place the client in high Fowler's position
C. Obtain a stat chest x-ray
D. Notify the healthcare provider immediately
CORRECT ANSWER: B. Place the client in high Fowler's position
Rationale: Using the ABC (Airway, Breathing, Circulation) priority framework, positioning the
client in high Fowler's position optimizes lung expansion and improves oxygenation
immediately. While administering diuretics, obtaining diagnostics, and notifying the provider
are important interventions, they do not take precedence over the immediate, independent
nursing action of improving the client's breathing status.
Question 2: A nurse is reviewing the medication administration record for a client prescribed
warfarin. Which laboratory value should the nurse monitor to evaluate the therapeutic effect
of this medication?
A. Platelet count
B. Prothrombin time (PT) and International Normalized Ratio (INR)
C. Activated partial thromboplastin time (aPTT)
D. Bleeding time
CORRECT ANSWER: B. Prothrombin time (PT) and International Normalized Ratio (INR)
Rationale: Warfarin is a vitamin K antagonist that affects the extrinsic pathway of coagulation.
PT and INR are the specific laboratory tests used to monitor warfarin therapy, with a
therapeutic INR typically ranging from 2.0 to 3.0 for most indications. aPTT monitors heparin
therapy, platelet count assesses for thrombocytopenia, and bleeding time is not used for
anticoagulation monitoring.
Question 3: A nurse is delegating tasks to an assistive personnel (AP). Which task is
appropriate for the nurse to delegate to the AP?
A. Assessing a client's pain level using a pain scale
B. Teaching a client about postoperative deep breathing exercises
C. Measuring and recording a client's vital signs
D. Evaluating a client's response to a newly prescribed medication
CORRECT ANSWER: C. Measuring and recording a client's vital signs
Rationale: According to the five rights of delegation, tasks that are routine, predictable, and do
not require clinical judgment can be delegated to assistive personnel. Measuring vital signs falls
within the AP's scope of practice. Assessment, teaching, and evaluation require the knowledge,
skill, and judgment of a licensed nurse and cannot be delegated.
Question 4: A nurse is caring for a client who is 2 hours postoperative following a total hip
arthroplasty. Which finding should the nurse report to the healthcare provider immediately?
,A. Pain level of 6 on a scale of 0 to 10
B. Slight swelling and bruising at the incision site
C. Sudden shortness of breath and chest pain
D. Temperature of 37.8° C (100° F)
CORRECT ANSWER: C. Sudden shortness of breath and chest pain
Rationale: Sudden shortness of breath and chest pain in a postoperative orthopedic client are
classic signs of pulmonary embolism, a life-threatening complication requiring immediate
intervention. Pain, expected postoperative swelling, and a low-grade fever are common
findings after surgery and do not require immediate provider notification unless they worsen
significantly.
Question 5: A nurse is preparing to administer insulin glargine and insulin aspart to a client
with type 1 diabetes mellitus. Which action should the nurse take?
A. Mix both insulins in the same syringe before administration
B. Administer insulin glargine first, followed by insulin aspart in separate injections
C. Administer insulin aspart first, followed by insulin glargine in separate injections
D. Shake the insulin glargine vial vigorously before drawing up the dose
CORRECT ANSWER: B. Administer insulin glargine first, followed by insulin aspart in separate
injections
Rationale: Insulin glargine is a long-acting basal insulin that should never be mixed with other
insulins because it has an acidic pH that can alter the action of other insulins. It must be
administered as a separate injection. Insulin aspart is a rapid-acting insulin typically given
before meals. Insulin glargine should not be shaken, as this can damage the protein structure.
Question 6: A nurse is assessing a client with suspected meningitis. Which finding is a classic
sign of meningeal irritation?
A. Positive Babinski reflex
B. Positive Brudzinski's sign
C. Negative Kernig's sign
D. Absent gag reflex
CORRECT ANSWER: B. Positive Brudzinski's sign
Rationale: Brudzinski's sign is a classic indicator of meningeal irritation, characterized by
involuntary flexion of the hips and knees when the nurse flexes the client's neck. Kernig's sign
(resistance to knee extension with hip flexed) is also indicative. A positive Babinski reflex
indicates upper motor neuron damage, and gag reflex assessment evaluates cranial nerve
function, not meningeal irritation.
Question 7: A nurse is caring for a client who is receiving a blood transfusion. Fifteen minutes
after the transfusion begins, the client reports chills and back pain. Which action should the
nurse take first?
A. Administer acetaminophen as prescribed
B. Stop the transfusion and keep the vein open with normal saline
C. Obtain a urine specimen to check for hemoglobin
D. Notify the healthcare provider immediately
CORRECT ANSWER: B. Stop the transfusion and keep the vein open with normal saline
,Rationale: Chills and back pain are early signs of an acute hemolytic transfusion reaction, a
medical emergency. The priority action is to stop the transfusion immediately to prevent
further infusion of incompatible blood, while maintaining venous access with normal saline for
potential medication administration. Notifying the provider and obtaining specimens are
important subsequent actions but do not precede stopping the transfusion.
Question 8: A nurse is developing a plan of care for a client with chronic obstructive
pulmonary disease (COPD). Which intervention should the nurse include to promote effective
airway clearance?
A. Encourage fluid intake of 3 to 4 liters per day if not contraindicated
B. Administer oxygen at 4 L/min via nasal cannula continuously
C. Position the client supine with the head of bed flat
D. Teach the client to cough forcefully and frequently
CORRECT ANSWER: A. Encourage fluid intake of 3 to 4 liters per day if not contraindicated
Rationale: Adequate hydration helps liquefy pulmonary secretions, making them easier to
expectorate and promoting airway clearance in clients with COPD. Oxygen should be titrated
carefully in COPD clients to avoid suppressing the hypoxic drive (typically 1-2 L/min). High
Fowler's or tripod positioning optimizes breathing. Forceful coughing can cause airway collapse
in COPD; huff coughing or controlled coughing techniques are preferred.
Question 9: A nurse is caring for a client who is experiencing an acute panic attack. Which
intervention is the priority?
A. Teach the client deep breathing exercises
B. Stay with the client and provide a calm, quiet environment
C. Administer a prescribed benzodiazepine immediately
D. Encourage the client to discuss the triggers of the panic attack
CORRECT ANSWER: B. Stay with the client and provide a calm, quiet environment
Rationale: During an acute panic attack, the client experiences intense fear and loss of control.
The priority nursing intervention is to provide safety, remain present, and reduce
environmental stimuli to help the client regain a sense of security. Teaching, medication
administration, and exploring triggers are appropriate after the acute episode subsides and the
client is more receptive.
Question 10: A nurse is assessing a client with a stage 3 pressure injury on the sacrum. Which
finding should the nurse expect?
A. Intact skin with non-blanchable redness
B. Full-thickness skin loss with visible subcutaneous fat
C. Full-thickness skin and tissue loss with exposed bone
D. Partial-thickness skin loss with a shallow open ulcer
CORRECT ANSWER: B. Full-thickness skin loss with visible subcutaneous fat
Rationale: A stage 3 pressure injury involves full-thickness skin loss where subcutaneous fat
may be visible, but bone, tendon, or muscle are not exposed. Stage 1 presents with intact skin
and non-blanchable redness. Stage 2 involves partial-thickness loss. Stage 4 includes full-
thickness tissue loss with exposed bone, tendon, or muscle.
, Question 11: A nurse is reviewing the laboratory results for a client with chronic kidney
disease. Which finding requires immediate intervention?
A. Serum potassium 5.8 mEq/L
B. Serum creatinine 2.1 mg/dL
C. Blood urea nitrogen (BUN) 28 mg/dL
D. Hemoglobin 10.2 g/dL
CORRECT ANSWER: A. Serum potassium 5.8 mEq/L
Rationale: A potassium level of 5.8 mEq/L indicates hyperkalemia, which can cause life-
threatening cardiac dysrhythmias and requires immediate intervention such as administration
of calcium gluconate, insulin with glucose, or sodium polystyrene sulfonate. Elevated creatinine
and BUN are expected in chronic kidney disease. Anemia (low hemoglobin) is common but not
immediately life-threatening.
Question 12: A nurse is caring for a client who is 36 weeks gestation and reports a sudden
gush of fluid from the vagina. Which action should the nurse take first?
A. Assess the fetal heart rate
B. Test the fluid with nitrazine paper
C. Place the client in a side-lying position
D. Notify the healthcare provider immediately
CORRECT ANSWER: A. Assess the fetal heart rate
Rationale: A sudden gush of fluid suggests rupture of membranes, which increases the risk for
umbilical cord prolapse and fetal compromise. The priority is to assess fetal well-being by
checking the fetal heart rate to detect any signs of distress. While testing the fluid, positioning,
and notifying the provider are important, fetal assessment takes precedence using the ABC and
fetal safety priorities.
Question 13: A nurse is administering medications to a client and discovers that a prescribed
dose was already given by the previous nurse. Which action should the nurse take first?
A. Document the error in the client's medical record
B. Assess the client for adverse effects
C. Notify the healthcare provider immediately
D. Complete an incident report
CORRECT ANSWER: B. Assess the client for adverse effects
Rationale: Following a medication error, the nurse's first priority is client safety. Assessing the
client for any adverse effects or signs of overdose addresses immediate physiological needs.
After ensuring client stability, the nurse should notify the provider, document appropriately,
and complete an incident report per facility policy.
Question 14: A nurse is caring for a client with a new diagnosis of tuberculosis. Which
transmission-based precaution should the nurse implement?
A. Contact precautions
B. Droplet precautions
C. Airborne precautions
D. Standard precautions only
CORRECT ANSWER: C. Airborne precautions
