A. Status epilepticus 
B. Myoclonic seizure
C. Absence Seizure
D. Tonic-clonic Seizure
E. Simple seizure

A. Epinephrine 
B. Clonidine 
C. Phenylephrine
D. Terbutaline 
E. Dipivefrin 

Answer: D. Terbutaline

15. The maximum daily dose of Acetaminophen for no longer than 10 days for pain is following?
A. 660 mg
B. 1200 mg
C. 2000 mg
D. 4000 mg

Answer: D. 4000 mg

16. Which one of the following would occur as a result of the inhibition of Na/K/ATPase?
a) Decreased intracellular Na concentration
b) Increased intracellular K concentration
c) Increased intracellular Ca concentration
d) Increased Na-glucose cotransport
e) Increased Na-Ca exchange

Answer: c) Increased intracity Ca concentration
The answer is C, inhibition of Na/K ATPase leads to an increase in intracellular Na concentration, increased intracellular Na then leads to decreased Na gradient across the cell membrane, thereby inhibiting the Ca/Na exchange and causing an increase in intracellular Ca concentration. This is the basis of the major mechanism of action of cardiac glycosides like Digoxin.

17. The rate of conduction of action potentials along a nerve will be increased by:
a) Stimulating the Na-K Pump
b) Inhibiting the Na-K Pump
c) Decreasing the diameter of the nerve
d) Myelinating the nerve
e) Lengthening the nerve fiber

Answer: d) Myelinating the nerve
The answer is D, myelin insulates the nerve thus increasing conduction velocity; action potentials can only be generated at the nodes of Ranvier, where there are breaks in the insulation. The activity of the Na/K pump does not directly affect the conduction or formation of action potentials. Decreasing nerve diameter would increase internal resistance and therefore slow down conduction velocity.

18. A patient diagnosed with type 2 diabetes is administered an oral dose of 0.1 mg chlorpropamide, an insulin secretagogue, and weak acid with a pKa of 5.0. What is the quantity of chlorpropamide absorbed at ph 2.0 from the stomach?

B. 05 mg
C. 50 μg
D. 90 μg
E. 9 μg

Answer: E. 9 μg

21. Process in which phagocytosis is enhanced by the deposit of ------------- e.g antibody or compliment component C3b on the surface of antigen?
A. Opsonins, Opsonization
B. Paratope
C. Plasma Cells 
D. Selection tolerance 
E. Natural killer cell 

Answer: A. Opsonins, and process is called Opsonisation 
Paratope: Antigen binding Site also known as antibody combining site on an antibody. Consists of interaction between the Vh and Vl domains of the antibody.

22. Undifferentiated cells found in the bone marrow and fatal liver that gives rise to nearly every leukocyte(immune cell) found in the body?
A. Mitogen
B. MHC haplotype
C. Lysozyme 
D. Commensal
E. Hematopoietic stem cells 

Answer: E. Hematopoietic stem cells 
Mitogen: Molecule that causes cells to undergo cells division 
MHC haplotype: major histocompatibility complex MHC genes both class I and class II expressed by an individual.
Lysozyme: A family of enzymes that breakdown walls of bacteria, especially gram positive bacteria.
Commensal: Normal microbial flora of digestive tract and skin. A Commensal relationship bw a microorganism and it's host is  one which the microorganisms benefits and host neither is harmed nor benifits.
