The fat-soluble vitamins include all of the following EXCEPT: A) A B) B C) K D) D
What is B. Vitamin B is not a fat-soluble vitamin. The fat-soluble vitamins are transported in the chylomicrons of the lymph; vitamin A undergoes a preliminary step of esterification with free fatty acid (usually palmitic acid) in the gastrointestinal mucosa, and is then transported via the chylomicrons of the lymph. To remember the fat-soluble vitamins, use the mnemonic AADEK.

All of the following statements about cerebrovascular disease are TRUE EXCEPT: A) Stroke mortality, which declined by 46% between 1968 and 1981, stabilized in the 1980's B) Auscultation for carotid bruits and non-invasive testing for carotid stenosis are routine screening procedures recommended by the U.S. Preventive Services Task Force (USPSTF) C) Advanced age is the most important risk factor for stroke D) Studies have shown increases in both stroke incidence and stroke mortality among smokers
What is B Screening for hypertension is recommended at regular intervals for men and women 16-64 years of age. However, the USPSTF found insufficient evidence to recommend for or against either auscultation for carotid bruits or non-invasive testing for carotid stenosis except in high-risk or symptomatic patients.

At what age does the USPSTF recommend that males begin routine screening for prostate cancer using prostate specific antigen (PSA) testing or digital rectal examination (DRE)? A) 40 years-old B) 50 years-old C) 60 years-old D) None of the above
What is D The U.S. Preventive Services Task Force (USPSTF) concludes that the evidence is insufficient to recommend for or against routine screening for prostate cancer using prostate specific antigen (PSA) testing or digital rectal examination (DRE). The USPSTF found good evidence that PSA screening can detect early-stage prostate cancer but mixed and inconclusive evidence that early detection improves health outcomes. Screening is associated with important harms, including frequent false-positive results and unnecessary anxiety, biopsies, and potential complications of treatment of some cancers that may never have affected a patient's health. The USPSTF concludes that evidence is insufficient to determine whether the benefits outweigh the harms for a screened population.

Regarding tuberculosis (TB), which of the following control strategies provides the best control? A) Elimination of the reservoir B) Prevention of spread of disease by good handwashing and personal hygiene C) Avoidance of contact with potential reservoirs D) Administration of a chemoprophylactic agent to kill the agent
What is D Isoniazid prophylaxis is given to patients with a positive skin test for TB to prevent re-activation of latent infection and secondary spread to others.

All of the following are true regarding vitamin K EXCEPT: A) Rich sources include green leafy vegetables, such as broccoli, spinach, brussel sprouts, and turnip greens, B) Vitamin K deficiency may lead to hemorrhaging caused by hypoprothrombinemia, C) Vitamin K is a fat-soluble vitamin, D) Vitamin K deficiency is not a major cause of worldwide morbidity and mortality of breast-fed newborns
What is D. Newborn infants are at increased risk for vitamin K deficiency because breast milk is low in vitamin K, very little vitamin K is transported across the placenta, prothrombin production by the neonatal liver is immature, and the fetal gut is sterile so that the normal intestinal flora responsible for synthesizing vitamin K are not typically present during the first few days of life. Adults at risk for vitamin K deficiency include those with diseases interfering with fat absorption or on prolonged antibiotic or TPN therapy.

The U.S. Preventive Services Task Force (USPSTF) strongly recommends that clinicians routinely screen all sexually active women aged ____ years and younger (and other asymptomatic women at increased risk for infection) for chlamydial disease. A) 24 B) 39 C) 34 D) 39
What is A The U.S. Preventive Services Task Force (USPSTF) strongly recommends that clinicians routinely screen all sexually active women aged 24 years and younger, and other asymptomatic women at increased risk for infection, for chlamydial infection. The USPSTF found good evidence that screening women at risk for chlamydial infection reduces the incidence of pelvic inflammatory disease and fair evidence that community-based screening reduces prevalence of chlamydial infection. The USPSTF concludes that the benefits of screening substantially outweigh the potential harms. Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen in the United States. There are estimated to be 3 million new infections each year. Chlamydial infection can cause urethritis, cervicitis, pelvic inflammatory disease (PID), and result in ectopic pregnancy, infertility, and chronic pelvic pain in women. In men, chlamydial infection can cause nongonococcal urethritis and acute epididymitis, and result in infertility, chronic prostatitis, reactive arthritis, and urethral strictures. In pregnant women, chlamydial infection is associated with adverse pregnancy outcomes, including preterm delivery and postpartum endometritis; perinatal transmission to infants can cause neonatal conjunctivitis and pneumonia. Chlamydial infection increases the risk of acquiring HIV infection. 70% to 90% of women and a large percentage of men with chlamydial infection are asymptomatic. The prevalence of asymptomatic infection varies widely depending on the population tested and individual characteristics and risk factors, ranging from 4% to 12% among female family planning clinic patients, 9% among female Army recruits, and 2% to 7% among female college students. Significant declines in prevalence have been noted over the last 10 years in areas where screening programs have been in place.

Prophylaxis with isoniazid (INH) for subclinical TB infection is recommended for all of the following groups EXCEPT: A) Individuals with AIDS or HIV infection B) Individuals with silicosis C) Nursing mothers D) Patients with unstable hepatic function

Symptoms of deficiency include progressive, symmetric paresthesias of the hands and feet, spasticity and ataxia of the legs, and loss of proprioception and vibratory senses.
What is vitamin B12. Pernicious anemia results from reduced absorption of vitamin B-12 (also referred to as cyanocobalamin) caused by impaired secretion of intrinsic factor from the gastric mucosa. Vitamin B-12 deficiency is associated with macrocytic anemia. The neurologic signs and symptoms are due to degenerative changes of the dorsal and lateral columns of the spinal cord. Dietary sources of vitamin B-12 include organ meats such as liver, shellfish such clams and oysters, certain fishes, poultry, eggs, and to some extent, milk and milk products.

Considered an elevated blood lead level in children ages 1-5 years old (must also get units correct).
What is 5 micrograms per deciliter. CDC: Experts now use a reference level of 5 micrograms per deciliter to identify children with blood lead levels that are much higher than most children’s levels. This new level is based on the U.S. population of children ages 1-5 years who are in the highest 2.5% of children when tested for lead in their blood. This reference value is based on the 97.5th percentile of the National Health and Nutrition Examination Survey (NHANES)’s blood lead distribution in children.
