WGU D444 ADULT HEALTH 1 OA V1 & V2
PRACTICE EXAM TEST BANK (2026
UPDATED) Q&AS WITH RATIONALES
This comprehensive question practice bank is meticulously
aligned with the updated 2026 Western Governors University
(WGU) D444 Adult Health 1 Objective Assessment. It delivers
high-yield multiple-choice questions covering advanced med-
surg nursing, pharmacology, and fluid/electrolyte balance,
complete with immediate bolded answers and italicized
rationales. Designed specifically to mimic Version 1 and
Version 2 exam patterns, this guide maximizes score
optimization and active recall for nursing students.
A nurse assesses a patient who is 6 hours postoperative abdominal
surgery and notes a heart rate of 115 bpm, blood pressure of 88/54
mmHg, and a urinary output of 15 mL over the past hour. Which action
should the nurse take first?
• A. Administer a scheduled dose of IV pain medication.
• B. Encourage the patient to increase oral fluid intake.
• C. Notify the healthcare provider and prepare for a fluid bolus.
• D. Document the findings as expected postoperative variations.
• Answer: C
, • Rationale: The patient is exhibiting signs of hypovolemic shock,
including tachycardia, hypotension, and oliguria. Immediate fluid
resuscitation is required to restore intravascular volume and
perfuse vital organs. Waiting or administering pain medication
without addressing hemodynamic instability could cause severe
complications.
A patient with a history of chronic obstructive pulmonary disease
(COPD) is receiving oxygen therapy via a nasal cannula at 2 L/min. The
nurse notes the patient's oxygen saturation (SpO₂) is 90%. What is the
most appropriate nursing action?
• A. Increase the oxygen flow rate to 6 L/min immediately.
• B. Maintain the current oxygen therapy and monitor respiratory
status.
• C. Switch the delivery system to a non-rebreather mask at 15
L/min.
• D. Prepare the patient for urgent endotracheal intubation.
• Answer: B
• Rationale: For patients with chronic hypercapnia, such as those
with severe COPD, the respiratory drive is often driven by hypoxia
rather than hypercapnia. Target SpO₂ levels for COPD patients are
typically between 88% and 92%. Increasing oxygen too high can
suppress their drive to breathe.
A nurse is caring for a patient diagnosed with deep vein thrombosis
(DVT) who is receiving a continuous intravenous heparin infusion. The
,patient's activated partial thromboplastin time (aPTT) is 110 seconds.
What is the priority nursing intervention?
• A. Increase the heparin infusion rate by 10%.
• B. Stop the infusion and prepare to administer protamine sulfate.
• C. Continue the infusion at the same rate and retest in 4 hours.
• D. Stop the infusion, notify the provider, and monitor for bleeding.
• Answer: D
• Rationale: A normal target therapeutic aPTT range for a patient
on heparin is typically 1.5 to 2.5 times the control value (around 60
to 80 seconds). An aPTT of 110 seconds indicates critical over-
anticoagulation, placing the patient at high risk for hemorrhage.
The infusion must be stopped and the provider notified
immediately.
A patient with Type 1 diabetes mellitus presents to the emergency
department with a blood glucose level of 450 mg/dL, positive serum
ketones, and arterial blood gas results showing a pH of 7.25. Which
provider order should the nurse implement first?
• A. Regular insulin 0.1 units/kg IV bolus.
• B. 0.9% Normal Saline infusion at 1,000 mL/hr.
• C. Subcutaneous administration of glargine insulin.
• D. Intravenous administration of sodium bicarbonate.
• Answer: B
• Rationale: In Diabetic Ketoacidosis (DKA), profound dehydration
occurs due to osmotic diuresis. Fluid resuscitation with isotonic
, saline is always the first priority to restore circulatory volume and
protect renal function before insulin therapy drops blood glucose
and shifts fluids intracellulary.
While assessing a patient with a chest tube connected to a water-seal
drainage system, the nurse notes continuous, vigorous bubbling in the
water-seal chamber. How should the nurse interpret this finding?
• A. The system is functioning normally with standard negative
pressure.
• B. The patient's lung has completely re-expanded.
• C. There is an air leak present somewhere within the system.
• D. The suction control chamber has lost its water volume.
• Answer: C
• Rationale: Intermittent bubbling in the water-seal chamber is
normal during expiration or coughing, but continuous, rapid
bubbling indicates an air leak in either the chest tube connections
or within the patient's pleural space.
A nurse is providing discharge teaching to a patient newly diagnosed
with heart failure who is prescribed furosemide. Which instruction is
vital to include?
• A. Restrict dietary intake of potassium-rich foods like bananas.
• B. Weigh yourself daily at the same time and report a gain of 3 lbs
in a day.
• C. Take the medication right before going to bed at night.
