A client receiving a continuous heparin infusion has the following
laboratory results:
aPTT: 124 seconds
Platelets: 226,000/mm³
Hemoglobin: 13.8 g/dL
INR: 1.1
Which action is most appropriate?
A. Continue infusion
B. Increase dose
C. Stop infusion
D. Give vitamin K - Correct Answer - C. Stop infusion
An aPTT of 124 seconds is significantly above the therapeutic range
(typically 60–80 seconds depending on protocol). The infusion should
be held and the provider notified. Vitamin K reverses warfarin, not
heparin.
A nurse assesses four postoperative clients. Which client should be seen
first?
A. Total knee replacement with pain 7/10
pg. 1
,B. Colectomy with urine output 40 mL/hr
C. Thyroidectomy reporting tingling around the mouth
D. Hip replacement requesting assistance to ambulate - Correct Answer -
C. Thyroidectomy reporting tingling around the mouth
Perioral tingling may indicate hypocalcemia caused by accidental
parathyroid injury following thyroid surgery and can rapidly progress to
laryngospasm or seizures.
A client with diabetic ketoacidosis has these laboratory findings:
Glucose: 612 mg/dL
Potassium: 5.8 mEq/L
pH: 7.18
Bicarbonate: 11 mEq/L
Which provider prescription should the nurse anticipate first?
A. Regular insulin infusion
B. Potassium chloride IV
C. Sodium bicarbonate IV
D. Dextrose 5% infusion - Correct Answer - A. Regular insulin infusion
After fluid resuscitation, continuous IV regular insulin is the primary
treatment for DKA. Potassium is initially elevated because of acidosis
but typically falls once insulin therapy begins.
A telemetry monitor displays the following rhythm:
Regular rhythm
Rate 168/min
pg. 2
,Narrow QRS
P waves not visible
The client reports palpitations but remains alert with a blood pressure of
118/72 mmHg.
Which intervention is appropriate?
A. Defibrillation
B. Vagal maneuver
C. Epinephrine
D. CPR - Correct Answer - B. Vagal maneuver
Stable supraventricular tachycardia should initially be treated with vagal
maneuvers, followed by adenosine if unsuccessful. Defibrillation is
reserved for pulseless rhythms.
A client with pneumonia receiving IV antibiotics suddenly becomes
restless. Assessment findings include:
RR 34/min
SpO₂ 83%
BP 146/88 mmHg
HR 124/min
Which action has the highest priority?
A. Repeat temperature
B. Increase oxygen
C. Encourage fluids
D. Obtain sputum sample - Correct Answer - B. Increase oxygen
pg. 3
, The client demonstrates worsening hypoxemia. Improving oxygenation
is the immediate priority before additional diagnostic interventions.
A client admitted with an ischemic stroke developed symptoms 90
minutes ago. Assessment reveals:
BP 174/94 mmHg
Glucose 112 mg/dL
CT scan: No hemorrhage
NIH Stroke Scale: 9
Which treatment should the nurse anticipate?
A. Aspirin only
B. Alteplase
C. Mannitol
D. Warfarin - Correct Answer - B. Alteplase
The client meets common criteria for thrombolytic therapy: symptom
onset within the treatment window, absence of intracranial hemorrhage,
and blood pressure below exclusion thresholds.
A client with acute decompensated heart failure arrives in the emergency
department with severe dyspnea. Assessment reveals crackles
throughout both lung fields, oxygen saturation 86% on room air, blood
pressure 176/92 mmHg, heart rate 118/min, and pink frothy sputum.
Which intervention should the nurse implement first?
A. Furosemide IV
B. High-Fowler's
C. Echocardiogram
pg. 4
