, WGU D236 OBJECTIVE ASSESSMENT AND PRACTICE EXAM WITH 100 QUESTIONS AND
ANSWERS
1. A patient's medical record indicates a staph skin infection that led to a boil on
the buttock region. Symptoms include redness, swelling, and pus formation.
Which additional symptom is most likely to be present?
• a) Cold to touch
• b) Warm to touch
• c) Cyanotic skin
• d) Dry, flaky skin
• Answer: b) Warm to touch
• Rationale: Inflammation causes vasodilation, leading to increased blood
flow and localized warmth.
2. A patient presents with anemia, jaundice, fever, and malaise caused by
destruction of red blood cells. Which infectious disease is most consistent with
these findings?
• a) Typhoid
• b) Malaria
• c) Influenza
• d) Tuberculosis
• Answer: b) Malaria
• Rationale: Malaria parasites destroy red blood cells, causing hemolytic
anemia and jaundice.
3. A patient sustains a second-degree burn on the left arm. The skin appears red
and swollen, and the patient reports significant pain. Which additional finding is
most expected?
• a) Skin blisters
• b) Complete loss of sensation
, • c) Painless eschar formation
• d) Black, leathery skin
• Answer: a) Skin blisters
• Rationale: Second-degree burns (partial thickness) involve the epidermis
and dermis, characterized by blister formation.
4. A 45-year-old male presents with elevated blood glucose levels and
complaints of frequent urination. Laboratory results reveal insulin resistance.
Which pathophysiological mechanism most commonly underlies this condition?
• a) Autoimmune destruction of beta cells
• b) Decreased sensitivity of insulin receptors
• c) Excessive secretion of glucagon
• d) Impaired glycogen breakdown
• Answer: b) Decreased sensitivity of insulin receptors
• Rationale: Type 2 diabetes results primarily from insulin resistance in
peripheral tissues.
5. Which electrolyte imbalance is most often seen in patients with adrenal
insufficiency (Addison's disease)?
• a) Hypernatremia
• b) Hyperkalemia
• c) Hypocalcemia
• d) Hypophosphatemia
• Answer: b) Hyperkalemia
• Rationale: Aldosterone deficiency leads to sodium loss and potassium
retention.
6. A patient with left-sided heart failure is likely to exhibit which clinical
manifestation first?
, • a) Peripheral edema
• b) Jugular venous distention
• c) Pulmonary congestion
• d) Hepatomegaly
• Answer: c) Pulmonary congestion
• Rationale: Left-sided failure causes increased pulmonary venous pressure
before systemic symptoms appear.
7. Which of the following is the most common cause of secondary
hypertension?
• a) Chronic kidney disease
• b) Cushing's syndrome
• c) Hyperthyroidism
• d) Primary aldosteronism
• Answer: a) Chronic kidney disease
• Rationale: CKD impairs blood volume and sodium regulation, making it the
most frequent cause.
8. During an acute asthma attack, airway obstruction is primarily due to:
• a) Fibrosis of alveolar walls
• b) Loss of surfactant
• c) Bronchial smooth muscle constriction and mucus production
• d) Destruction of elastic tissue
• Answer: c) Bronchial smooth muscle constriction and mucus production
• Rationale: Asthma involves bronchoconstriction, mucosal edema, and
mucus hypersecretion.
9. Which immune cell type is primarily responsible for antibody production?
• a) T-helper cells
