Case-Based Nursing Practice & Detailed Explanations
Question 1: A 72-year-old male with a history of Type 2 Diabetes Mellitus
presents to the clinic with a non-healing ulcer on his right heel. The wound is
3cm x 2cm, with visible tendon and bone at the base, and there is no
surrounding erythema or edema. The patient has a diminished dorsalis pedis
pulse. Which stage of the wound healing process is primarily impaired in this
patient, leading to the chronicity of this wound?
A. Hemostasis
B. Inflammatory
C. Proliferative
D. Maturation
CORRECT ANSWER: B. Inflammatory
Rationale: The chronicity of wounds, particularly in diabetic patients with peripheral
vascular disease, is often due to a prolonged or dysregulated inflammatory phase. The
lack of erythema and edema, despite the presence of a severe wound, is a classic sign of
impaired inflammation and a reduced ability to fight infection and initiate the
subsequent proliferative phase. While maturation is the final phase, the primary
impairment is the failure to progress from inflammation.
Question 2: A 45-year-old female with a history of systemic lupus
erythematosus (SLE) presents with complaints of bilateral hand pain, stiffness,
and swelling in her proximal interphalangeal (PIP) and metacarpophalangeal
(MCP) joints for the past two months. Which pathophysiological process best
explains the joint manifestations in this patient?
A. Deposition of monosodium urate crystals in the joint space.
B. Autoantibody-mediated immune complex deposition leading to synovitis.
C. Degenerative changes in the articular cartilage from mechanical stress.
D. A bacterial infection leading to purulent joint fluid.
CORRECT ANSWER: B. Autoantibody-mediated immune complex deposition
leading to synovitis.
Rationale: SLE is a systemic autoimmune disease characterized by the production of
autoantibodies against nuclear and cytoplasmic antigens. These form immune
complexes that deposit in various tissues, including the synovium of joints, leading to an
inflammatory response (synovitis). This results in the non-erosive arthritis commonly
,seen in SLE. Option A describes gout, C describes osteoarthritis, and D describes septic
arthritis.
Question 3: A premature neonate in the NICU develops respiratory distress
syndrome (RDS). The primary underlying cause of this condition is a
deficiency of which substance, leading to increased alveolar surface tension
and atelectasis?
A. Surfactant
B. Alpha-1 antitrypsin
C. Immunoglobulin A
D. Elastin
CORRECT ANSWER: A. Surfactant
Rationale: Respiratory Distress Syndrome in premature infants is caused by a deficiency
of pulmonary surfactant, a lipoprotein complex produced by Type II alveolar cells.
Surfactant reduces surface tension within the alveoli, preventing their collapse at end-
expiration (atelectasis). Without sufficient surfactant, the alveoli collapse, leading to
severe hypoxemia and respiratory failure. Alpha-1 antitrypsin deficiency is a cause of
emphysema in adults.
Question 4: A 65-year-old male is diagnosed with a new onset of tonic-clonic
seizures. An MRI of the brain reveals a solitary, well-circumscribed, extra-
axial mass arising from the dura mater. Which type of intracranial tumor is
most consistent with these findings?
A. Glioblastoma multiforme
B. Astrocytoma
C. Meningioma
D. Metastatic adenocarcinoma
CORRECT ANSWER: C. Meningioma
Rationale: Meningiomas are the most common primary brain tumors and are typically
benign, slow-growing, and extra-axial (arising from the meninges, specifically the
arachnoid cells). They are often well-circumscribed and attached to the dura.
Glioblastoma multiforme and astrocytomas are intra-axial tumors arising from glial cells.
Metastatic tumors can be extra-axial, but a solitary, well-circumscribed mass attached to
the dura is highly characteristic of a meningioma.
Question 5: A patient with chronic kidney disease (CKD) is found to have a
hemoglobin level of 8.5 g/dL and a hematocrit of 25%. The primary
pathophysiological mechanism for this anemia is:
,A. Increased destruction of red blood cells.
B. Decreased production of erythropoietin.
C. Acute blood loss from uremic platelet dysfunction.
D. Iron deficiency from poor dietary intake.
CORRECT ANSWER: B. Decreased production of erythropoietin.
Rationale: The kidneys are the primary site of erythropoietin (EPO) production. In CKD,
the damaged renal parenchyma fails to produce adequate EPO, leading to a
hypoproliferative anemia. While blood loss, iron deficiency, and increased destruction
can occur, the primary mechanism is the failure of EPO production. This is
characterized by a normochromic, normocytic anemia.
Question 6: A 58-year-old male with a history of hypertension and
hyperlipidemia presents with sudden-onset, painless vision loss in his left eye.
Funduscopic examination reveals a pale, edematous retina with a cherry-red
spot at the fovea. This clinical picture is most consistent with which of the
following?
A. Retinal detachment
B. Open-angle glaucoma
C. Central retinal artery occlusion
D. Diabetic retinopathy
CORRECT ANSWER: C. Central retinal artery occlusion
Rationale: The classic presentation of a central retinal artery occlusion (CRAO) is
sudden, painless, monocular vision loss. Funduscopic findings include a pale, milky-
white retina due to ischemia and edema, with a characteristic "cherry-red spot" at the
fovea, which appears red because the choroidal circulation is preserved and visible
through the thin macula. This is often caused by an embolus from atherosclerotic carotid
artery disease.
Question 7: A patient with a history of peptic ulcer disease is prescribed a non-
selective NSAID for chronic back pain. Which pathophysiological mechanism
is responsible for the increased risk of gastric ulcer formation associated with
this medication?
A. Increased gastric acid secretion.
B. Inhibition of prostaglandin synthesis.
C. Decreased gastric mucosal blood flow.
D. Overgrowth of Helicobacter pylori.
CORRECT ANSWER: B. Inhibition of prostaglandin synthesis.
, Rationale: NSAIDs inhibit cyclooxygenase (COX) enzymes, which are necessary for the
synthesis of prostaglandins. Prostaglandins are crucial for maintaining the integrity of
the gastric mucosal barrier by stimulating mucus and bicarbonate secretion and
promoting mucosal blood flow. The inhibition of prostaglandin synthesis leaves the
gastric mucosa vulnerable to damage from gastric acid, leading to ulceration. H. pylori is
a separate risk factor, not directly caused by NSAIDs.
Question 8: A 35-year-old woman with Graves' disease is being evaluated for
an ophthalmopathy. The exophthalmos seen in this condition is primarily
caused by:
A. A primary tumor of the optic nerve.
B. Increased intraocular pressure from aqueous humor buildup.
C. Edema and hypertrophy of extraocular muscles due to an autoimmune inflammatory
reaction.
D. A deficiency of thyroid hormone leading to myxedema.
CORRECT ANSWER: C. Edema and hypertrophy of extraocular muscles due to
an autoimmune inflammatory reaction.
Rationale: Graves' ophthalmopathy is an autoimmune condition where the fibroblasts
and adipocytes in the retro-orbital tissues are targeted by the same immune processes
that cause hyperthyroidism. This leads to inflammation, edema, and hypertrophy of the
extraocular muscles and an increase in orbital fat, pushing the eyeball forward
(exophthalmos). It is not due to a tumor, glaucoma, or myxedema (which causes
periorbital edema, not exophthalmos).
Question 9: A 6-year-old child is brought to the emergency department with
acute onset of stridor, a barking cough, and fever. The most likely diagnosis is
viral laryngotracheobronchitis (croup). The primary site of airway obstruction
in this condition is the:
A. Bronchioles
B. Alveoli
C. Subglottic area of the larynx
D. Mainstem bronchi
CORRECT ANSWER: C. Subglottic area of the larynx
Rationale: Croup, or acute laryngotracheobronchitis, is characterized by inflammation
and edema in the subglottic region of the larynx. Because the subglottic area is the
narrowest part of the pediatric airway, even mild edema can cause significant
obstruction, leading to the classic inspiratory stridor and barking cough. Bronchioles
and alveoli are affected in conditions like bronchiolitis and pneumonia.
