The CDC recommends employing food and water precautions to avoid infectious diseases from contaminated food and water. Which of the following precautions are recommended to avoid traveler's diarrhea (select all that apply) A) Food should be fully cooked food and served hot. B) Avoid salads and unpasteurized milk products, including cheese and yogurt. C) Raw fruits and vegetables need not be avoided. D) Alcohol-based sanitizers are effective against all pathogens. E) Contaminated tap water can cause infection if inadvertently inhaled while showering.

A, B, and E. Contaminated food and water can transmit a variety of infectious diseases to travelers, including shigellosis, E. coli infection, bacillary dysentery, cryptosporidiosis, hepatitis A, norovirus, and typhoid fever. They can also be a source of infection for cholera and diseases caused by parasites. Many of these diseases are transmitted by the fecal-oral route, including swallowing and inhaling aerosols or droplets. Travelers should select food carefully and avoid raw or undercooked meat, fish, and shellfish. If the sanitation and hygiene are inadequate in a region, travelers should avoid salads, uncooked vegetables, and unpasteurized milk, milk products, and fruit juices. In these areas, travelers should only eat food that is fully cooked and served hot or fruit that has been washed in clean water and peeled by the person who is eating it. Raw fruits and vegetables should be avoided unless peeled, and eggs should be thoroughly cooked. Travelers should thoroughly wash their hands with soap and water before eating and after using the bathroom, changing diapers, or after coming into direct contact with preschool-aged children, animals, or feces. Alcohol-based sanitizers should be used when soap and water are not available, but they are not effective against norovirus and cryptosporidium. C. FALSE: Raw fruits and vegetables should be avoided. If eaten, they should be peeled by the person who will consume them. D. FALSE: Alcohol-based sanitizers are not effective against norovirus or cryptosporidium. All alcohol-based sanitizers should contain >60% alcohol.

Which of the following OTC medications can be used for motion sickness (select all that apply)? A) Dimenhydrinate B) Promethazine C) Diphenhydramine D) Meclizine E) Scopolamine

A, C, and D. TRUE: Dimenhydrinate is Dramamine. Meclizine is Bonine. These are anticholinergic agents that are sold over the counter to prevent motion sickness. They should be taken before travel. Cyclizine (Marezine) is another OTC anticholinergic agent used to treat motion sickness. Diphenhydramine (Benadryl) is a first-generation antihistamine that can be useful for treating nausea and prevention of motion sickness. Patients should be informed that these agents are sedating and should not use them while consuming alcohol or taking other central nervous system depressants. They also should not drive or operate heavy machinery when taking these agents. B. FALSE: Promethazine is only available by prescription. E. FALSE: Scopolamine is only available by prescription.

What is the quantification of the course of toxicant absorption, distribution, biotransformation, and excretion? A) Toxicokinetics B) Toxicodynamics C) Bioavailability D) Biological half-life

A. Toxicodynamics refers to the effects of toxicants and their metabolites on body systems. Half-life is the time it takes for a toxicant to lose half of its activity. Bioavailability is a subcategory of absorption.

Which model is a prospective, hospital-based system designed to standardize units of hospital activity in order to link prices? A) Medicare Severity-Diagnosis Related Groups B) International Statistical Classification of Diseases and Related Health Problems C) Resource-Based Relative Value Scale D) Ambulatory Payment Classifications

A. TRUE: Diagnosis-related groups (DRGs) were designed to describe all types of patient care in an acute care hospital. The classification of groups allows hospitals to manage costs and allows payors, such as Medicare, to bind reimbursements to DRGs.

Which of the following is incorrect with regards to screening for sexually transmitted diseases (STDs)? A) All patients being evaluated for STDs should be offered counseling and testing for HIV. B) Asymptomatic women with risk factors for STDs should be screened for gonococcal or chlamydial infections. C) HIV-infected patients should be screened annually for N. gonorrhoeae. D) Pregnant women should be screened for Chlamydia trachomatis. E) All sexually active women and pregnant women need to be screened for herpes infections.

ANSWER: E. E. This is the incorrect (false) statement: The US Preventive Services Task Force (USPSTF) recommends against routine serologic screening for herpes simplex virus (HSV) in asymptomatic pregnant women and in asymptomatic adolescents and adults. According to the 2010 CDC treatment guidelines for STDs, all patients being evaluated for STDs should be offered HIV testing. All women with risk factors for STDs should be screened for a gonococcal or chlamydial infection annually. Hepatitis B screening should be offered to men who have sex with men (MSM), patients with a history of multiple sex partners, or those who abuse intravenous drugs. It is recommended that sexually active MSM undergo annual testing for N. gonorrhoeae, Chlamydia trachomatis, HIV, and syphilis. Pregnant women should be screened for Chlamydia trachomatis, HIV, hepatitis B, and syphilis infections. Patients with HIV should be screened annually for N. gonorrhoeae, Chlamydia trachomatis, syphilis, hepatitis B, and hepatitis C. Local and state public health departments should be kept informed of chancroid, Chlamydia trachomatis, N. gonorrhoeae, acute hepatitis B and C, HIV, and syphilis.

In which circumstance is a test for cure recommended after treatment of an uncomplicated gonorrhea infection? A) If the patient is a male who has sex with men B) If treatment was with a cefixime-based regimen C) If infection was asymptomatic at the time of diagnosis D) If the initial diagnosis was made without culture

B. Uncomplicated gonorrhea infections treated with a ceftriaxone-containing combination regimen do not require a test of cure if the patient has no further symptoms. However, a test of cure should be performed if an alternate treatment regimen is used. Men who have sex with men have a higher prevalence of resistant infection.

How long after leaving an endemic area should a traveler continue to take chloroquine for malaria prophylaxis? A) 3 days B) 1 week C) 4 weeks D) 8 weeks

C. Chloroquine prophylaxis should begin 1 week prior to exposure and end 4 weeks following exposure. Mefloquine and doxycycline are also continued for 4 weeks after exposure. Atovaquone-proguanil and primaquine only need to be continued for 1 week following exposure.

When designing a study to investigate the effects of gender and geographic location on weight, which of the following measurement scales describes the variables of weight and gender, respectively? A) Ratio, ordinal B) Nominal, interval C) Ratio, nominal D) Ordinal, nominal

C. Ratio, nominal. Explanation: Weight is measured on a ratio scale, which has a zero point, allows ranking, and contains equal intervals. Gender is measured on a nominal scale, which places people or things into categories that are mutually exclusive but not ordered. The other choices are wrong becase: (A) Gender is a nominal or categorical variable. (B) The orders are reversed. An interval variable is a measurement where the difference between 2 values has meaning, but there is no absolute zero. A ratio scale is a type of interval scale. (D) In ordinal variables, the order is important, but the interval differences between values are not equal. Ordinal scales give no information about the difference in quantity between variables.

Researchers are designing a randomized trial and would like to estimate the sample size that will be needed. What information is needed in order to make this calculation? A) Loss to follow-up rate B) Treatment compliance rate C) Level of statistical significance D) Disease prevalence in population

All patients should be decontaminated before any treatment or stabilization after radiation exposure. TRUE or FALSE?

FALSE Patients should be stabilized then decontaminated, beginning with the removal of clothing. After the patient has been stabilized, he or she should be surveyed with alpha and Geiger counters to evaluate radioactivity, which should be documented on an anatomic chart and used to determine the sequence of decontamination of intact skin. Decontamination should begin with debridement of open wounds.

Prussian blue should be administered to patients potentially exposed to radioactive iodine. TRUE or FALSE?

A county's public health department is currently investigating a recent outbreak of measles in the community. Eight individuals have developed measles since the outbreak began. Which additional factor would be needed in order to calculate an attack rate? A) Number of people vaccinated against measles B) Number of people with previous measles infection C) Number of people exposed to 1 of 8 affected individuals D) Number of people at risk for measles infection

D. Attack rate is defined as the number of people in whom a certain illness develops divided by the total number of people at RISK.

Which of the following changes occurs with exposure to high altitude in air travel? A) Significant reductions in atmospheric pressure begin to occur at 10,000 feet above sea level. B) Increased temperature can contribute to increased physiological consequences of altitude. C) At the same altitude, barometric pressure at the equator is lower than at distances from the equator. D) Barometric pressure is the primary determinant of the partial pressure of oxygen in inspired air. E) FiO2 decreases with altitude

D. Barometric pressure is the primary determinant of the partial pressure of oxygen in inspired air (PiO2). It decreases with altitude but increases in hyperbaric environments at depth. The fraction of oxygen in inspired air does not change with altitude. The relationship between barometric pressure, FiO2, and PiO2 is expressed as PiO2 = FiO2 x barometric pressure. In addition, the PiO2 is reduced by the partial pressure of water vapor that is obtained during transport of air into the lungs (47 mmHg). This relationship is expressed as PiO2 = 0.21 - (barometric pressure - 47 mmHg). A. FALSE: Significant reductions in atmospheric pressure occur beyond a critical height of 2500 meters or 8200 feet in altitude. B. FALSE: Factors that increase the physiological consequences of altitude include decreased temperature and deteriorating weather. C. FALSE: Because of a large mass of cold air above the equator, the barometric pressure at a given altitude is higher at the equator than at distances from the equator. E. FALSE: The FiO2 is the same at all altitudes. The partial pressure of oxygen changes with altered barometric pressure.

A drug was approved for the treatment of depression in adults 2 years ago. Since then, there have been several case reports of neutropenia in patients taking the drug. Researchers are now planning a clinical trial to further evaluate any association between the drug and neutropenia. What is the most appropriate classification for this trial, according to US Food and Drug Administration (FDA) standards? A) Phase I B) Phase II C) Phase III D) Phase IV

D. Phase IV testing is also known as post-marketing surveillance and is used to further monitor and study drugs that have already been approved.

Which of the following patients should be screened for colorectal cancer with a fecal immunochemical test (FIT), according to the United States Preventive Services Task Force (USPSTF)? A) A 45-year-old male with 20 pack-year history of tobacco use B) A 78-year-old male with diabetes C) An 87-year-old male whose father died of colon cancer at age 85 D) A 55-year-old male who had a negative colonoscopy 4 years earlier E) A 56-year-old male who had a negative flexible sigmoidoscopy at age 50

E. The USPSTF recommends screening for colorectal cancer in all individuals after age 50 and continuing until age 75. The median age at diagnosis is 68 years. Colorectal cancer is most frequently diagnosed among adults ages 65-74 years; the median age at death from colorectal cancer is 68 years. There are a variety of screening modalities with recommendations. For patients who choose to be screened with flexible sigmoidoscopy, the USPSTF recommends flexible sigmoidoscopy every 5 years or every 10 years in combination with FIT. Evidence has shown that flexible sigmoidoscopy alone reduces deaths from colorectal cancer and, when combined with FIT, reduces colorectal cancer-specific mortality even more. The USPSTF also recommends aspirin use for the primary prevention of cardiovascular disease and colorectal cancer in average-risk adults. A. FALSE: The USPSTF did not review specific populations at risk, but for most adults, the most important risk factor is older age. The recommendations are for screening starting at age 50. B. FALSE: The USPSTF recommends that the decision to screen for colorectal cancer in adults ages 76-85 years should be made after taking into account the patient's overall health and prior screening history. C. FALSE: The USPSTF does not recommend routine screening in individuals over age 86. In addition, a family history of colorectal cancer at an early age is a risk factor. D. FALSE: Colonoscopy is indicated every 10 years as a screening method.

Cost-benefit analysis compares different interventions and outcomes relative to _____?

Expected benefits minus the total cost of implementation. Cost-benefit analysis is a technique to assist with decision making. In a cost-benefit analysis, expected benefits of an intervention or project are subtracted from the total cost of implementation, measured in monetary units.

The US Preventive Services Task Force advises against screening men and nonpregnant women for asymptomatic bacteriuria. TRUE or FALSE?

TRUE The US Preventive Services Task Force advises against screening men and nonpregnant women for asymptomatic bacteriuria; there is adequate evidence to suggest that screening is ineffective in improving clinical outcomes. In older adults with chronic urinary incontinence, ABU can be difficult to differentiate from symptomatic UTI. In such cases, delaying treatment for 1 week while offering supportive treatment such as increased fluid intake is an acceptable therapeutic option. Up to 50% of women with UTI will have symptom relief or show spontaneous improvement in 1 week without antibiotics.

Over the course of a month, a physician gives all his patients a cancer screening test that he developed in his clinic's lab. Thirty patients test positive, but when he has the patients undergo the gold standard diagnostic test, only 20 of them actually have cancer. What is the positive predictive value of his screening test?

The positive predictive value is the proportion of patients who test positive who actually have the disease. In this case, 20 out of 30 patients who tested positive have the disease (20/30 = 0.67, or 67%).

Toxoplasma gondii causes infections in immunosuppressed patients, but those who are immunocompetent are usually asymptomatic. It is transmitted through the ingestion of infectious oocysts that may come from cat litter that is contaminated with cat feces.

Which Type of error refers to the failure to reject the null hypothesis when a difference exists?

Type II error. (conclude there is no difference when there is) Explanation: The failure to reject the null hypothesis when a true difference exists in the larger population refers to a type II error. The null hypothesis states that the difference between 2 groups is the result of random chance alone. The alternate hypothesis states that differences within a sample are influenced by a non-random cause. Beta refers to the probability of making a Type II error. Type I error (conclude there is a difference when there is not) refers to the rejection of the null hypothesis when no true difference exists in the population. Confounding refers to errors made as a result of the researcher failing to account for an extraneous variable that directly or inversely correlates with both the dependent and independent variables. Statistical power refers to the likelihood that a study will detect an effect when there is an effect present. It is the probability that a test will reject a false null hypothesis and is inversely related to the probability of making a type II error. Alpha refers to the probability of making a type I error.

Yellow fever vaccination YF-VAX contraindications include...

Women who are breastfeeding should not receive the vaccine. Patients with hypersensitivity to gelatin, eggs, or chicken products should not receive this vaccine. Patients who are taking Enbrel or Humira should not receive the vaccine. Explanation: YF-VAX is a live viral vaccine. It is given in a single dose 10 days or more before travel, but some individuals may require a booster dose after 10 years. This includes patients who are immunocompromised, pregnant women, and those with increased exposure. This vaccine is contraindicated in patients with hypersensitivity to egg or chick embryo protein or gelatin; infants <9 months; patients with acute or febrile disease; and immunosuppressed patients, including those with HIV infection, leukemia, lymphoma, thymic disease, generalized malignancy, or immunosuppression due to drugs or radiation. It is also contraindicated in breastfeeding women. It should be used with caution in adults older than 60 years of age, according to ACIP guidelines, as there is an increased risk of vaccine-associated neurologic disease. Pregnant women should avoid use unless travel to a high-risk area is unavoidable since they may not produce an adequate immune response to the vaccine.
