INTRODUCTION
WGU D444 Adult Health 1 is an adult medical-surgical nursing course at Western Governors
University. Publicly available course materials identify D444 as Adult Health 1 and show
preparation centered on adult patient assessment, clinical judgment, disease processes, nursing
interventions, pharmacology, and evaluation of patient outcomes. (Studocu)
The course is intended for nursing students developing the knowledge and clinical-reasoning
skills required to care for adult patients with acute and chronic health alterations. The available
D444 study materials emphasize cardiovascular and respiratory disorders, gastrointestinal and
hepatic conditions, renal and endocrine disorders, neurologic and sensory problems, infections,
fluid and electrolyte disturbances, and medication management. (Docsity)
Mastery of Adult Health 1 is important because medical-surgical nursing requires nurses to
integrate assessment findings, laboratory results, medications, pathophysiology, safety
considerations, and prioritization rather than simply recognize isolated disease facts. D444
preparation materials specifically emphasize clinical prioritization and application of nursing
knowledge to patient scenarios. (Studocu)
Important format note: I could not verify an official public source establishing a 200-question
D444 Objective Assessment or an official D444 percentage blueprint. Therefore, the 200-
question set below is an original comprehensive practice examination, not a reproduction of
an actual WGU assessment. Public sources describe D444 as an Objective Assessment, but third-
party materials vary in their reported question counts and should not be treated as an official
blueprint. (Naxlex)

QUESTIONS 1-200
Q1: A nurse is caring for a client admitted with acute decompensated heart failure. The
client has dyspnea, bilateral crackles, an oxygen saturation of 86% on room air, and pink
frothy sputum. Which intervention should the nurse implement first?
A) Obtain the client's daily weight
B) Place the client in high-Fowler position and administer prescribed oxygen
C) Restrict the client's oral fluids to 1,000 mL/day
D) Administer the scheduled oral potassium supplement
,Correct Answer: B
Rationale: The client has severe pulmonary congestion with impaired oxygenation, making
airway and breathing the immediate priorities. High-Fowler positioning improves lung
expansion and decreases venous return, while prescribed oxygen addresses hypoxemia. Daily
weight and fluid restriction are important interventions but do not immediately correct the life-
threatening oxygenation problem. Potassium administration does not address the acute
respiratory compromise and could be unsafe without current laboratory data.
Q2: A client with chronic obstructive pulmonary disease is receiving oxygen at 2 L/min by
nasal cannula. The client becomes increasingly somnolent, and the respiratory rate
decreases from 20/min to 10/min. Which action should the nurse take first?
A) Increase oxygen flow to 6 L/min
B) Assess the client's respiratory status and obtain an arterial blood gas as prescribed
C) Remove the oxygen immediately
D) Encourage the client to drink fluids
Correct Answer: B
Rationale: New somnolence and decreasing respiratory rate may indicate worsening
hypercapnia and respiratory failure. The nurse should immediately reassess respiratory status
and obtain objective data such as an ABG. Increasing oxygen substantially without assessment
may worsen ventilation-perfusion problems in some susceptible clients. Oxygen should not be
abruptly discontinued in a hypoxemic client. Hydration does not address the immediate
respiratory deterioration.
Q3: A client with pneumonia has a temperature of 39.1°C (102.4°F), respiratory rate of
30/min, and oxygen saturation of 89%. The provider prescribes a sputum culture and
broad-spectrum antibiotics. Which action should the nurse perform first?
A) Administer the antibiotic
B) Obtain the sputum specimen before administering the antibiotic
C) Encourage oral fluids
D) Place the client in Trendelenburg position
Correct Answer: B
Rationale: When a sputum culture is ordered before antimicrobial therapy, the specimen should
ideally be obtained first so antibiotics do not reduce the likelihood of identifying the causative
organism. Antibiotic therapy should then be started promptly. Fluids may assist secretion
clearance but are secondary. Trendelenburg positioning can impair respiratory mechanics and
is inappropriate for this client.
, Q4: A client with cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding
best indicates that the medication is producing the intended therapeutic effect?
A) Urine output increases
B) Mental status improves and the client has regular soft stools
C) Abdominal girth decreases rapidly
D) Serum albumin returns to normal
Correct Answer: B
Rationale: Lactulose decreases intestinal ammonia absorption by promoting conversion of
ammonia to ammonium and increasing fecal elimination. Improved cognition and a pattern of
regular soft stools indicate therapeutic response. Increased urine output is not the principal
therapeutic outcome. Lactulose does not rapidly reverse ascites or normalize albumin
production.
Q5: A client with chronic kidney disease has a serum potassium level of 6.8 mEq/L and
reports muscle weakness. Which finding requires the nurse's immediate attention?
A) Serum creatinine of 4.2 mg/dL
B) BUN of 68 mg/dL
C) New peaked T waves on the ECG
D) Mild ankle edema
Correct Answer: C
Rationale: Severe hyperkalemia can cause life-threatening cardiac dysrhythmias. Peaked T
waves are an important ECG manifestation of hyperkalemia and require immediate intervention.
Elevated creatinine and BUN are expected with significant renal dysfunction, while mild edema
is concerning but less immediately life-threatening than electrical cardiac instability.
Q6: A client with diabetic ketoacidosis has a glucose level of 520 mg/dL, pH 7.18, and
bicarbonate of 11 mEq/L. Which prescription should the nurse anticipate as an initial
priority?
A) Administer long-acting insulin only
B) Begin isotonic IV fluid replacement
C) Restrict fluids
D) Administer oral sodium bicarbonate
Correct Answer: B
Rationale: Significant dehydration from osmotic diuresis is a major component of DKA. Initial
management generally includes rapid isotonic fluid replacement, followed by insulin and
electrolyte management. Long-acting insulin alone is not appropriate for acute DKA. Fluid
