and Influenza Insights | William Paterson

1. Which of the following is a primary clinical manifestation of iron-deficiency anemia?
A. Splenomegaly
B. Pallor of the skin and mucous membranes
C. High blood pressure
D. Increased energy levels
Answer: B
Rationale: Pallor occurs because there is a reduced amount of oxyhemoglobin in the blood.
This leads to a pale appearance in the skin, nail beds, and conjunctiva. It is one of the most
common physical signs used to identify suspected anemia in a clinical setting.
2. Which neurotransmitter is most commonly targeted by Selective Serotonin Reuptake
Inhibitors (SSRIs) used in treating depression?
A. Dopamine
B. Acetylcholine
C. GABA
D. Serotonin
,Answer: D
Rationale: SSRIs work by blocking the reabsorption of serotonin into neurons. This makes
more serotonin available to improve transmission of messages between neurons.
Increasing serotonin levels often helps improve mood and emotional balance in patients
with depression.
3. What is the primary mode of transmission for the Influenza virus?
A. Respiratory droplets
B. Contaminated water
C. Direct blood contact
D. Skin-to-skin contact
Answer: A
Rationale: Influenza is primarily spread through large-particle respiratory droplets
produced when an infected person coughs or sneezes. These droplets can land in the
mouths or noses of people who are nearby. It is less common but possible for the virus to
be spread via contaminated surfaces.
4. Pernicious anemia is caused by a deficiency in which of the following?
A. Vitamin C
B. Vitamin D
C. Vitamin B12
, D. Iron
Answer: C
Rationale: Pernicious anemia is specifically a type of vitamin B12 deficiency anemia. It
occurs when the body cannot absorb enough B12 due to a lack of intrinsic factor in the
stomach. Without B12, the body cannot make enough healthy red blood cells, leading to
megaloblastic changes.
5. In the DSM-5 criteria for Major Depressive Disorder, how long must symptoms persist to
warrant a diagnosis?
A. At least 2 weeks
B. At least 1 week
C. At least 3 days
D. At least 6 months
Answer: A
Rationale: The clinical diagnosis of Major Depressive Disorder requires symptoms to be
present for at least a two-week period. These symptoms must represent a change from
previous functioning. At least one of the symptoms must be either depressed mood or loss
of interest/pleasure.
6. Which age group is generally considered at high risk for complications from Influenza?
A. Adults aged 18 to 25
