Question

Which of the following may cause peptic ulcer disease?

Answer 1

Correct Answers:

Helicobacter pylori infection

Rationale :

💎 H. pylori colonizes the gastric mucosa and produces urease, generating ammonia that alkalinizes the microenvironment and disrupts mucosal defenses.

💎The organism triggers chronic inflammation (gastritis) and increases gastrin release, promoting acid secretion that contributes to gastric and duodenal ulcers.

💎Eradication of H. pylori (e.g., PPI + two antibiotics) significantly reduces ulcer recurrence, underscoring its causal role in peptic ulcer disease.

💎Diagnostic tests such as the urea breath test, stool antigen, or biopsy-based methods confirm active infection.

💎Recognizing H. pylori as a major etiology guides targeted therapy and long-term prevention of ulcer complications like bleeding and perforation.

Answer 2

Correct Answers:

Homeostasis is a steady and dynamic state within the body

Rationale :

🔷Homeostasis refers to a dynamic equilibrium—internal conditions are kept within narrow ranges despite external changes.

🔷It is maintained by feedback mechanisms, primarily negative feedback (e.g., temperature, glucose, and pH regulation).

🔷The term emphasizes constancy through change, not stasis; variables fluctuate around set points to keep physiology stable.

🔷Key examples include insulin–glucagon balance, baroreceptor-mediated blood pressure control, and ventilatory regulation of CO₂.

🔷Understanding this concept helps nurses anticipate compensatory responses and identify when regulation fails (instability).

Answer 3

Correct Answers:

Ventricles contract and blood is ejected from the heart

Rationale :

🔶Systole begins with ventricular contraction, raising pressure and closing the AV valves (S1).

🔶As pressure exceeds the aortic and pulmonary pressures, the semilunar valves open and stroke volume is ejected.

🔶The phase is governed by preload, afterload, and contractility, which determine ejection fraction and cardiac output.

🔶Systole ends when ventricular pressure falls below great vessel pressure, leading to semilunar valve closure (S2).

🔶Accurate identification of systole is essential when correlating heart sounds, pulses, and blood pressure dynamics.

Answer 4

Correct Answers:

Left-sided facial droop

Rationale :

🟣A right cerebral hemisphere stroke typically causes contralateral (left-sided) motor and facial deficits due to corticospinal and corticobulbar tract crossing.

🟣Findings often include left hemiparesis, left facial droop, and left hemisensory loss.

🟣Right hemisphere injury commonly produces spatial–perceptual deficits, inattention/neglect of the left side, and impulsivity.

🟣Speech is often relatively spared unless there is atypical language lateralization, but prosody may be affected.

🟣Early recognition of a contralateral facial droop helps localize the lesion and expedite reperfusion decisions.

Answer 5

Correct Answers:

Alcohol use

Rationale :

🟠Chronic alcohol exposure is a leading cause of chronic pancreatitis, driving toxic–metabolic injury and proteinaceous ductal plugs with calcifications.

🟠Repeated inflammation leads to fibrosis, progressive exocrine insufficiency (steatorrhea, malabsorption), and eventual endocrine failure (diabetes).

🟠Patients often report recurrent epigastric pain radiating to the back, weight loss, and fat-soluble vitamin deficiencies.

🟠Imaging may show pancreatic calcifications and ductal irregularities, consistent with long-standing alcohol-related damage.

🟠Management centers on alcohol cessation, pancreatic enzyme replacement, nutrition support, and pain control.

Answer 6

Correct Answers:

Increased head size

Rationale :

🟢Acromegaly (excess growth hormone after epiphyseal closure) causes acral and craniofacial enlargement, including increased head size and frontal bossing.

🟢Patients develop coarse facial features, mandibular prognathism, macroglossia, and enlarged hands/feet.

🟢Soft-tissue overgrowth can deepen the voice, cause sleep apnea, and produce organomegaly (e.g., cardiomegaly).

🟢Metabolic effects include insulin resistance and elevated IGF-1, the key biomarker for diagnosis.

🟢Untreated disease increases cardiovascular risk; therapy targets the pituitary adenoma (surgery, medication, or radiation).

Answer 7

Correct Answers:

The damaged kidney is unable to secrete erythropoietin

Rationale :

🔵In ESRD/CKD, the kidney’s peritubular interstitial cells fail to produce adequate erythropoietin (EPO).

🔵Low EPO leads to reduced bone marrow erythropoiesis, causing a normocytic, normochromic anemia.

🔵Consequences include fatigue, decreased exercise tolerance, and higher cardiovascular strain.

🔵Management often requires erythropoiesis-stimulating agents plus assessment of iron stores (ferritin, TSAT) and iron supplementation as needed.

🔵Correcting EPO deficiency improves quality of life and reduces transfusion requirements in CKD.

Answer 8

Correct Answers:

7.35 to 7.45

Rationale :

✅Normal arterial blood pH is 7.35–7.45, reflecting tightly controlled acid–base homeostasis.

✅Deviations below 7.35 indicate acidemia, and above 7.45 indicate alkalemia, each with specific respiratory or metabolic etiologies.

✅Buffer systems (bicarbonate, proteins, phosphate) and renal and respiratory compensation maintain this range.

✅The Henderson–Hasselbalch relationship (HCO₃⁻/PaCO₂) explains the interplay between kidneys and lungs.

✅Sustained pH disturbances impair enzyme function, cardiac rhythm, and CNS activity, requiring prompt evaluation.

Answer 9

Correct Answers:

Superficial bum

Rationale :

🌞 A superficial (first-degree) burn involves only the epidermis, as seen in most sunburns.

🌞Clinical features include erythema, tenderness, and dry skin without blisters; capillary refill is brisk.

🌞Healing is typically rapid (3–6 days) with no scarring, though transient desquamation may occur.

🌞Management focuses on cool compresses, oral analgesics, and hydration of the skin; topical antimicrobials are not usually required.

🌞Education targets UV protection (sunscreen, clothing, shade) to prevent deeper burns and photodamage.

Answer 10

Correct Answers:

Jaundice

Rationale :

🟡Jaundice denotes yellow discoloration of tissues from elevated bilirubin, with scleral icterus being a classic early sign.

🟡Causes span prehepatic (hemolysis), intrahepatic (hepatocellular injury), and posthepatic (cholestasis/obstruction) mechanisms.

🟡Evaluation includes LFTs, fractionated bilirubin, and, when indicated, imaging for biliary obstruction.

🟡In the clinical context of abdominal distention and nausea, concomitant liver or biliary pathology should be considered.

🟡Prompt recognition guides appropriate workup and targeted management to prevent complications like cholestatic pruritus or coagulopathy.
