Lymphocytes that originate from stem cells in the bone marrow pass through the thymus gland where they mature and develop into activated T-lymphocytes, able to respond to antigens elsewhere in the body. 2. Answer c. A drug’s half-life is the time required for the level of that drug in serum to decrease from 100% to 50%; thus, it relates to how long the drug remains effective in the blood stream. A drug with a shorter half-life needs to be administered more often or manufactured in an extended- or time-released form. 3. Answer A. An emmetropic eye is an eye that can sufficiently refract light rays from an object 6 m away to focus a clear image on the retina. All the others are disorders or abnormalities of vision. 4. Answer A. The abbreviation YAG (yttrium aluminum garnet) is seen in association with many modern surgical lasers, most commonly linked with holmium (Ho:LAG), neodymium (Nd:YAG), and erbium (Er:YAG). It is also seen in combination with a manufacturer or product name, as in Lasertek YAG, Lumonics YAG, and Carl Zeiss YAG. 5. Answer c. The ciliary body is the thickest portion of the vascular tunic, one of three tunic layers of the wall of the eyeball. It extends from the ora serata to a point just behind the sclerocorneal junction. The ciliary body consists of the ciliary processes and the ciliary muscle. 6. Answer b. The other value ranges provided are for: (A) ammonia, (C) bicarbonate, (D) BUN. 7. Answer c. Candida albicans, is yeast that necessitates treatment with an antifungal medication, such as clotrimazole. This active ingredient interferes with fungal cell membranes and prohibits the production of ergosterol, essential to the stability of the cell membrane. 8. Answer b. Ipsilateral refers to being on the same side, so in this case, the only region that would be found on the same side (left) would be the left hypochondriac region. 9. Answer A. Eicosanoids and triglycerides are both lipids, dipeptides are amino acid pairs necessary in the formation of proteins, and monosaccharides are simple sugars, or carbohydrates. 10. Answer b. Often a precursor to TMJ, requiring the use of a mouth guard, bruxism is the compulsive act of grinding or clenching one’s teeth, typically at night. Most patients are not aware of the compulsion but do develop symptoms of headache, pain in the jaw, and neck stiffness as a result. 11. Answer A.

Brovana is a longacting beta2-agonist used long-term to control symptoms of chronic obstructive pulmonary disease, administered through a standard jet nebulizer. 13. Answer D. Normal levels of serum potassium are 3.7 to 5.2 mEq/L. 14. Answer b. Normal levels of serum sodium are 135 to 145 mEq/L. 15. Answer c. Rocky Mountain spotted fever, ehrlichiosis, and anaplasmosis are tick-borne rickettsial diseases (TBRD) and are transmitted bacterium, not viruses. These three diseases are common in the United States, along with some emerging diseases such as the Rickettsia parkeri infection. Lyme disease is also a bacterium, but not rickettsial; it is caused by Borrelia burgdorferi. 16. Answer c. It may not seem like much of a difference, but even slight abnormalities in the electrolytes can cause big problems. In this case, a potassium level of 7 is considered hyperkalemic and can lead to EKG abnormalities such as peaked T waves, prolongation of the PR interval, an absent P wave with widening of the QRS complex, and finally ventricular tachycardia or fibrillation. 17. Answer c. An anesthesiologist uses the American Society of Anesthesiologists grade (ASA) to assess the patient’s risk associated with anesthesia and surgery. An excellent article explaining the different levels is here: http://www.ispub.com/ostia/index. php?xmlFilePath=journals/ija/vol15n1/ asa.xml 18. Answer c.
