TOPIC 1: SMALL CELL LUNG CANCER
8 Questions • 9.5% of Exam • Focuses on the characteristics, treatment, and prognosis of small cell lung cancer.
QUESTION 1
Parathyroid Function
Correct Answer: Produce Parathyroid Hormone and regulate Serum Calcium (Ca+)
Rationale: The parathyroid hormone plays a crucial role in maintaining serum calcium levels by stimulating the release of
calcium from bones, increasing its absorption in the intestine, and promoting its reabsorption in the kidneys, thus regulating
its concentration in the blood.
This regulatory function is essential for various physiological processes, including muscle contraction, nerve impulse
transmission, and bone mineralization, highlighting the importance of parathyroid hormone in calcium homeostasis.
QUESTION 2
Sickle Cell Disease Treatments
Correct Answer: * Hydroxyurea - decrease pain and decrease need for transfusion
* Hydration - to expand circulatory volume and clear clumps
* 02 - to increase 02 carrying capacity
* Kids should get all vaccines to avoid illness which can exacerbate sickle cell crisis pain.
Rationale: Hydroxyurea is a correct answer because it helps to decrease the frequency and severity of sickle cell crises by
reducing the production of abnormal hemoglobin, thus decreasing the need for transfusions and alleviating pain. The other
options, hydration, 02, and vaccinations, are also correct because they address specific needs in the management of sickle
cell disease, including increasing circulatory volume, enhancing oxygen delivery, and preventing infections that can
exacerbate symptoms.
QUESTION 3
Human Leukocyte Antigen (hla-b*5801) Allele adverse affect on Zyloprim (Allopurinol)
Correct Answer: * If allele is positive then patient will potentially develop life-threatening reaction to Zyloprim
(Allopurinol) which is used to treat gout, kidney stones, or increased uric acid
* MONITOR LIVER FUNCTION HEPATOTOXICITY.
Rationale: The hla-b*5801 allele is associated with an increased risk of severe liver toxicity when taking Zyloprim
(Allopurinol), a medication used to treat various conditions. This is why monitoring liver function is crucial for patients with
this allele to prevent potential lifethreatening reactions, making the given statement a correct answer to the question.

QUESTION 4
If patient fails COPD treatment with LABA, what should you try next?
Correct Answer: LABA + LAMA
Long acting beta agonist + Long acting muscarinic agonist.
Rationale: The addition of a long-acting muscarinic agonist (LAMA) to a long-acting beta agonist (LABA) treatment is a
logical next step because it targets the bronchodilatory effects of both the beta-2 receptors and the muscarinic receptors,
providing comprehensive bronchodilation and symptom relief. This combination is supported by clinical trials that have
demonstrated improved lung function and reduced exacerbations in patients with chronic obstructive pulmonary disease
(COPD) who have failed monotherapy with a LABA.
QUESTION 5
Worst prognosis of all lung cancers
Correct Answer: Small Cell
* Survival time if untreated = 8% at 5 years.
Rationale: Small Cell Lung Cancer has the worst prognosis because it grows and spreads rapidly, often by the time
symptoms appear, making it challenging to treat effectively. The 8% survival rate at 5 years indicates that most patients with
untreated Small Cell Lung Cancer will not survive long after diagnosis, highlighting its aggressive nature.
QUESTION 6
Small Cell Lung Carcinoma (SCLCs)
Correct Answer: * Most common neuroendocrine lung tumor; 15% of all lung CA but 25% of lung CA deaths
* Most tumors start in central part of lung
* Most caused by tobacco smoking
* Rapid growth & metastasize early and widely.
Rationale: The provided description matches the characteristics of Small Cell Lung Carcinoma (SCLC) because it highlights
the tumor's aggressive nature, rapid growth, and early metastasis, which are hallmarks of SCLC. This aggressive behavior,
combined with its high prevalence and mortality rate, particularly among smokers, further supports the identification of SCLC
as the correct answer.
