WGU D444 ADULT HEALTH 1 OA EXAM 300 ACTUAL
QUESTIONS AND CORRECT ANSWERS WITH
RATIONALE LATEST UPDATE ALREADY GRADED A+
ASSURED PASS
The WGU D444 Adult Health 1 OA Exam is a comprehensive, Next Generation
NCLEX-style assessment for nursing students covering essential medical-surgical
nursing concepts. It evaluates clinical judgment across major body systems,
including cardiovascular, respiratory, endocrine, renal, gastrointestinal,
neurological, and musculoskeletal disorders, as well as fluid and electrolyte
imbalances and perioperative care. The exam features multiple-choice, select-all-
that-apply, bow-tie, and case study questions that test prioritization, delegation,
and critical thinking. Candidates must demonstrate the ability to apply nursing
interventions, interpret laboratory values, identify medication side effects, and
recognize complications. A thorough understanding of pathophysiology,
pharmacology, and evidence-based practice is essential for success on this
objective assessment.
Section 1: Cardiovascular Disorders
1. A patient is admitted with chest pain, diaphoresis, and nausea. What is the
priority nursing action?
A) Administer sublingual nitroglycerin
B) Obtain a 12-lead EKG
C) Administer aspirin
D) Apply oxygen
Answer: C
Rationale: Aspirin is a priority because it is an antiplatelet agent that reduces
mortality in acute myocardial infarction by preventing further clot formation. It
should be administered immediately upon suspicion of acute coronary syndrome,
along with obtaining a rapid EKG and other interventions .
,2. A patient prescribed digoxin reports nausea, vomiting, and seeing yellow halos
around lights. What is the priority nursing action?
A) Administer the next dose as scheduled
B) Hold the dose and assess the apical pulse
C) Encourage the patient to eat a small snack
D) Notify the provider immediately
Answer: B
Rationale: Nausea, vomiting, and visual disturbances (yellow-green halos) are
classic signs of digoxin toxicity. The nurse should hold the dose, assess the apical
pulse, and then notify the provider based on assessment findings .
3. A patient with heart failure and a low-sodium diet selects which meal indicating
understanding of teaching?
A) Canned soup and crackers
B) Fresh fruits and vegetables
C) Processed cheese sandwich
D) Pickles and deli meat
Answer: B
Rationale: Fresh fruits and vegetables are naturally low in sodium and are
appropriate choices for a low-sodium diet. Canned soup, processed cheese, pickles,
and deli meats are high in sodium and should be avoided .
4. A patient is prescribed a beta-blocker for hypertension. The nurse should
monitor for which side effect?
A) Tachycardia
B) Bradycardia and hypotension
C) Hyperglycemia
D) Bronchodilation
Answer: B
Rationale: Beta-blockers decrease heart rate and cardiac output, leading to
bradycardia and hypotension. Patients should be monitored for dizziness, fatigue,
and signs of heart block .
5. A patient with chronic heart failure is prescribed metoprolol succinate. Which
assessment finding requires the nurse to hold the medication?
A) Heart rate of 68 beats per minute
B) Blood pressure of 130/80 mmHg
C) Heart rate of 54 beats per minute
D) Respiratory rate of 16 breaths per minute
,Answer: C
Rationale: Metoprolol is a beta-blocker that decreases heart rate. The medication
should be held if the heart rate is below 60 beats per minute (or per provider order),
as bradycardia can indicate excessive beta-blockade .
6. A patient with hypertension is prescribed lisinopril. The nurse should monitor
for which adverse effect?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Hypomagnesemia
Answer: A
Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing
aldosterone secretion, leading to decreased potassium excretion. Patients should
have potassium levels monitored regularly .
7. A patient with a history of myocardial infarction is prescribed a statin. The
primary purpose of this medication is to:
A) Reduce blood pressure
B) Lower LDL cholesterol
C) Prevent blood clots
D) Improve heart rate
Answer: B
Rationale: Statins are HMG-CoA reductase inhibitors that lower LDL cholesterol
and reduce the risk of cardiovascular events. They are a cornerstone of secondary
prevention after MI .
8. A patient with heart failure is experiencing dyspnea at rest. The nurse should
position the patient in which position?
A) Supine position
B) High-Fowler's position
C) Prone position
D) Left lateral position
Answer: B
Rationale: High-Fowler's position (sitting upright) reduces venous return to the
heart, decreases pulmonary congestion, and improves breathing in patients with
heart failure .
9. A patient with infective endocarditis is at risk for which complication?
A) Heart failure
, B) Systemic embolization
C) Valve destruction
D) All of the above
Answer: D
Rationale: Infective endocarditis can lead to heart failure (from valve damage),
systemic embolization (from vegetations breaking off), and valve destruction.
Prompt antibiotic therapy is essential .
10. A patient with deep vein thrombosis is prescribed heparin. Which laboratory
value should the nurse monitor to evaluate therapeutic effect?
A) PT/INR
B) aPTT
C) Platelet count
D) Hemoglobin
Answer: B
Rationale: Heparin therapy is monitored using the activated partial thromboplastin
time (aPTT). The therapeutic goal is typically 1.5 to 2.5 times the normal value .
11. A patient on warfarin has an INR of 4.5. The nurse should:
A) Administer the next dose as ordered
B) Hold the dose and notify the provider
C) Administer vitamin K immediately
D) Increase the next dose
Answer: B
Rationale: The therapeutic INR range for most indications is 2.0 to 3.0. An INR of
4.5 indicates supratherapeutic anticoagulation and increased bleeding risk,
requiring the dose to be held and the provider to be notified .
12. A patient with peripheral artery disease reports leg pain that occurs with
walking and resolves with rest. This is known as:
A) Rest pain
B) Intermittent claudication
C) Venous insufficiency
D) Neuropathic pain
Answer: B
Rationale: Intermittent claudication is ischemic muscle pain that occurs with
exercise and resolves with rest. It is a hallmark symptom of peripheral artery
disease caused by atherosclerosis .
