Answer:
Streptomycin.
Explanation:
Antibiotics are the chemicals that inhibit the growth or may directly kill the bacteria or other pathogenic organisms. The viral infections cannot be treated by the antibiotics.
β-lactam antibiotics are the drugs that contains beta-lactam ring in its structure. This inhibits the synthesis of cellwall in bacteria and prevent the individual from the bacterial infection. Among the listed antibiotics, all antibiotics are β-lactam antibiotics except streptomycin. Streptomycin cannot be used to inhibit the bacteria.
Thus, the correct answer is option (e).
Final answer:
Streptomycin does not belong with the other options because it is not a ß-lactam antibiotic but an aminoglycoside, functioning by a different mechanism and chemical structure.
Explanation:
Among the options listed, streptomycin does not belong with the others because it is not a type of ß-lactam antimicrobial. The categories including penicillin, cephalosporin, and monobactam are all types of ß-lactam antibiotics, which are characterized by their chemical structure containing a ß-lactam ring.
This structure is crucial for their mode of action, which involves inhibiting the synthesis of the bacterial cell wall. In contrast, streptomycin belongs to the aminoglycoside class of antibiotics, which function by binding to the 30S subunit of the bacterial ribosome, thereby inhibiting protein synthesis. This difference in mechanism and chemical structure is what sets streptomycin apart from the ß-lactam antibiotics.
Hydrogen peroxide is a more robust inhibitor of bacterial growth than 70% isopropyl alcohol and Betadine. However, isopropyl alcohol and/or Betadine are used to prepare skin prior to surgery but hydrogen peroxide is not. Why might this be?
Answer:
Because it destroys healthy skin cells.
Explanation:
Hydrogen peroxide is an antiseptic that is more potent than 70% isopropyl alcohol and betadine but even then it is not used by doctors because it has a damaging effect on skin cells.
Our cells contain catalase enzyme which reacts with hydrogen peroxide and release reactive oxygen species which cause cytotoxic effect. So applying hydrogen peroxide on the wound to clean it destroys the cells and delay the healing of the wound.
Therefore due to damaging side effects of hydrogen peroxide on human cells, it is generally not used by doctors.
Binge drinking is defined for men as drinking ___________ or more drinks in one sitting; for women, who tend to weigh less and whose bodies absorb alcohol less efficiently, binge drinking is defined as ___________ drinks in one sitting.
Answer:
5 drinks for men and 4 drinks for women
Explanation:
Binge drinking can be seen as a usual situation when having fun with your friends or enjoying a social activity of any kind; however, it does not mean that the person who binge drinks is an alcoholic.
According to the National Institute on Alcohol Abuse and Alcoholism, binge drinking is considered when a man drinks 5 or more drinks and women 4 or more drinks in around 2 hours giving as a result an alcohol concentration of 0.08 grams or more.
Answer:
5 drinks for men and 4 drinks for women
Explanation:
A privately owned nursing home hires mostly Hispanic women. The hiring manager believes that only Hispanic women could "fit in" and therefore does not hire anyone who does not meet this profile. This practice is likely to beA) permissible because most of the local residents are HispanicB) discriminatory on the basis of national origin in violation of Title VIIC) permissible because of the employment-at-will doctrineD) permissible because the nursing home is a private company
Answer:
B) discriminatory on the basis of national origin in violation of Title VII
Explanation:
Title VII of the Civil Rights Act covers both private sector employers and public sectors employers, including labor organizations.
Regarding employment decisions as it relates to national origin, Title VII states that it is unlawful to use an individual’s national origin as a yardstick or use such as a basis to discriminate or disqualify a job applicant seeking employment based on his nationality. It holds that equal opportunity should be given to all applicants during employment decisions.
The practice of the manager employing only Hispanic women because he believes they "fit in" for the job, thereby depriving other women of other national origin of the same opportunity is likely discriminatory on the basis of national origin. This is a violation of the Title VII Act.

Flow of air____________.
a. directly proportional to the resistance, and flow decreases as the pressure of the system increases.
b. is directly proportional to the resistance, and flow increases as the resistance of the system increases.
c. is directly proportional to a pressure gradient, and flow increases as the resistance of the system increases.
d. None of the answers are correct.
e. is directly proportional to a pressure gradient, and flow decreases as the resistance of the system increases.
Answer:
E. is directly proportional to a pressure gradient, and flow decreases as the resistance of the system increases.
Explanation:
The correct answer is:
the flow of air is directly proportional to a pressure gradient, and flow decreases as the resistance of the system increases
Airflow is directly proportional to pressure gradient and inversely proportional to system resistance, which means as resistance increases, airflow decreases.
Explanation:The flow of air is directly proportional to a pressure gradient and inversely proportional to the resistance of the system. As the pressure increases, the flow will also increase, provided that the resistance remains constant. However, if the resistance increases, the flow will decrease. This principle is analogous to Ohm's law in electricity, where current is inversely proportional to resistance. In terms of fluid dynamics, Bernoulli's equation indicates that if pressure is constant and kinetic energy per unit volume increases, the potential energy per unit volume must decrease. Therefore, applying this understanding to the given options, the correct answer is e. is directly proportional to a pressure gradient, and flow decreases as the resistance of the system increases.

A 6-year-old boy has just come in from school and wants a snack. The mother is trying to maintain a heart-healthy diet for him by following the Dietary Guidelines for Americans. What would be the best snack the mother could give him?
Answer: yogurt and banana oat cookies
Explanation: yogurt is a good source of protein and is high in calcium for healthy bones and some contain some helpful bacteria for the kids digestive system while banana oat cookies get their sweetness from mashed banana instead of refined sugar which is prone to causing diabetes.
A heart-healthy snack for a 6-year-old should include fresh fruits, vegetables, low-fat dairy, and whole grains while avoiding added sugars and fats. Engaging the child in snack selection and preparation can encourage healthy eating habits. It's beneficial to keep these healthy snacks easily accessible.
For a 6-year-old child adhering to the Dietary Guidelines for Americans, the best snack would integrate components from different food groups while avoiding high sugar and high-fat options. Offering a variety of nutrient-dense foods is pivotal. Suitable snacks could include washed and chopped fresh vegetables like celery and carrots, "grab-and-go" fruits such as apples or bananas, low-fat dairy products like yogurt without added sugars, or whole-grain crackers. It is beneficial to have these healthy snacks readily accessible for children to encourage heart-healthy eating habits from a young age.
It is important to ensure that snacks for children provide necessary nutrition without leading to overfeeding. Engaging the child in selecting and preparing their snacks, perhaps by letting them choose their favorite fruits or vegetables at the store or by assisting in washing or arranging the snacks, can make snack-time both educational and enjoyable. This approach not only teaches children about healthy eating habits but also about kitchen safety and meal planning.
Therefore, snacks that are low in sugars and fats and high in nutrients, like fresh fruits and unsweetened dairy products, alongside whole grains and vegetables are aligned with the heart-healthy diet recommendations for children. Engaging children in the process helps to establish these patterns early on, laying the groundwork for lifelong healthy eating habits.

Put the events associated with the mechanism of action of cholera in the correct sequential order.
1. Adenylyl cyclase is turned on, producing cAMP.
2. Cholera binds to intestinal cells.
3. CFTR channels are opened, increasing Cl-diffusion into the lumen of the intestine.
4. Cholera is brought into the cell via endocytosis.
Answer:
2,4,1 and 3.
Explanation:
Cholera toxin is an epidemic disease caused by the bacteria. This mainly causes watery diarrhea and results in the extreme loss of fluid from the body and causes electrolyte deficiency in the body.
The cholera is a toxin is produced by the bacteria. This toxin has the ability to enter in the intestinal cells. This enters into the cell by the endocytic process. This toxin causes he activation of cAMP in the body. cAMP activates the protein kinase A, this causes the opening of CFTR channel. This channel opens the chloride diffusion and results in the loss of chlorine ions from the body.
Thus, the correct order is 2,4,1 and 3.

Answer:
a. iron-fortified infant rice cereal
Explanation:
It's okay to feed babies with foods that are rich in iron, but rice cereal is not always the best option. Still, out of the given choices, this one is the healthiest alternative. The rice cereal that is rich in iron is a good way to provide your baby with it, since they are born with reserves of it, but they start to use them once they're 6 months and older. Babies that are breastfed, need an alternative, as formula is rich in iron and parents wouldn't have to worry about it. The iron found in cereal is not absorbed well and that's why expert suggest that once a baby starts to eat solid food, it's better to feed them with poultry, tofu, red meat, beans, pasta, etc.

"Helena believes that people with psychological disorders are suffering from diseases that have physical causes that can be diagnosed, treated, and sometimes even cured. Helena believes in the _____ model of psychological disorders"
Answer:
Helena believes in the medical model of psychological disorders"
Explanation:
The medical model of psychological disorders is based on psychiatry, which is a branch form medicine. Psychiatry has a therory that sustains that psychological dissorders have organic causes. There for the way they treat pacients is with medication. Medical vision of treatment belives in the possibility of curing someone with medication as other medical problem. There are medicine for anxiety or depression, or psycosis. This means medicine help treat the syntoms, so that they can be control or managed.
Helena believes in the biomedical model of psychological disorders, which approaches these disorders similarly to physical diseases, using medication and other physical treatments.
Explanation:Helena believes that people with psychological disorders are suffering from diseases that have physical causes that can be diagnosed, treated, and sometimes even cured. Helena believes in the biomedical model of psychological disorders. The biomedical model treats psychological disorders as it would any physical disease, often relying on medication and other physical treatments to address these conditions. This model contrasts with other approaches that may include cultural systems, psychoneuroimmunology, and the biopsychosocial model, which consider psychological, social, and cultural factors in the diagnosis and treatment of psychological disorders.
Cultural attitudes towards psychological disorders vary significantly across different societies. For example, the treatment and societal integration of conditions like schizophrenia and gender dysphoria can vary between cultures such as those in the United States, Thailand, and Japan. Understanding these cultural dynamics is an essential aspect of the field of medical anthropology.

An infection control nurse has identified a problem related to infection control procedures on a medical unit that has a high census of clients diagnosed with tuberculosis. The nurse has decided to conduct an in-service education program for the staff about the required transmission-based precautions. The nurse determines that the program was successful based on which statement by the staff?
Answer and Explanation:
Tuberculosis is an infectious and transmissible disease that primarily affects the lungs, although it can affect other organs and / or systems. The disease is caused by the Mycobacterium tuberculosis or Koch's bacillus. It is an air spread disease and occurs from the inhalation of aerosols from the airways during the speech, sneezing, or coughing of people with active tuberculosis, who release aerosol-containing particles into the air that contain the bacillus.
With the initiation of treatment, transmission tends to decrease gradually and, generally, after 15 days of treatment, it is greatly reduced. However, control measures should be implemented such as covering the mouth with the arm or handkerchief when coughing, keeping the environment well ventilated and with plenty of sunlight. The bacillus is sensitive to sunlight, and air circulation enables dispersion of infecting particles. Thus, ventilated environments with direct natural light reduce the risk of transmission.
So the program was sucessful if the number of patients decreased, as the disease can be controlled veru easily by that measures controls listed above.
The success of the in-service education program would be apparent if the staff can thoroughly articulate and properly carry out tuberculosis transmission precautions like special ventilation, using masks, strict hand hygiene, diligent sterilization of medical equipment and stringent isolation procedures.
Explanation:The ability of the staff to articulate and properly implement tuberculosis transmission precautions such as maintaining special ventilation in rooms, using masks, careful hand hygiene, diligent sterilization of equipment, and stringent isolation procedures of patients, indicates the success of the in-service education program. The staff should also know how to respond if a potential transmission or breakdown in the infection control protocol occurs, which includes seeking immediate medical consultation and patient management. Furthermore, understanding how to adopt special protocols, including the use of personal protective equipment and practicing preventive measures such as immediate disinfection upon entry and exit, is crucial in preventing the transmission of tuberculosis and other infectious diseases.
