1. a teacher who provides opportunities for children to master challenges and to become independent is creating a pro-social environment. reducing mental health issues. reducing aggression. creating a stress-free environment. 2. which of the following is not an effect of toxic stress? may cause developmental delays hormone, such as cortisol, increase heart rate increase may cause reaction to higher thresholds of stress 3. when a child behaves in a way that is not typical of his or her age and developmental level, it is difficult for a teacher to know if there is a mental health problem because appropriate behaviors might be learned with more experience and practice. observed behaviors cannot be reliably linked to mental health status. teachers are rarely qualified to identify mental health issues. most atypical behavior can be attributed to cultural differences. 4. a teacher who learns that a child recently lost a sibling and talks to the parents about how they manage behavior at home is employing a(n) promotion strategy. functional assessment. attachment strategy. transformation strategy. 5. arianna is feeling frustrated. to her learn to interact appropriately with others, her teacher, who encourages pro-social behavior, talks to arianna about her skills, and provides puzzles that challenge her. accomplishments. feelings, and brainstorms ways to ease her frustration. friends and how much they love her. 6. which of the following is not a goal of conducting a functional assessment? finding ways to prevent the problem behavior completing documentation for the health record teaching the child appropriate behaviors determining why a problem behavior occurs 7. according to the pyramid model supporting social emotional competence in infants and young children, which of the following is an example of a nurturing and responsive relationship? provide to children with mental issues. adults attend carefully to children’s cues. there are opportunities for children to appropriately express feelings. teach friendship skills. 8. how can mental health affect a child’s development? mental health has an indirect relationship to cognitive learning. mental health is tied to children’s perceptual well-being. lack of mental health diminishes children’s response to stress. a lack of mental health can affect the architecture of the brain. 9. teaching a child to recognize and describe feeling is an example of nurturing and responsive relationships. targeted social emotional supports. intensive intervention. high-quality, supportive environments. 10. a preschool teacher spots three-year-old alexandra angrily throwing a ball at logan, and the teacher intervenes by offering to play catch with alexandra while letting her know that throwing toys is not appropriate. this is an example of a(n) promotion strategy. clinical intervention. engagement strategy. transformation strategy.

The herpes viruses are important enveloped dna viruses that cause disease in vertebrates and in some invertebrates such as oysters. some of the human forms are herpes simplex virus (hsv) types i and ii, causing facial and genital lesions, and the varicella zoster virus (vsv), causing chicken pox and shingles. each of these three actively infects nervous tissue. primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. the virus can later reactivate, replicate again, and infect others. in electron micrographs of hsv infection, it can be seen that the intact virus initially reacts with cell surface proteoglycans, then with specific receptors. this is later followed by viral capsids docking with nuclear pores. afterward, the capsids go from being full to being "empty." which of the following best fits these observations? a) viral capsids are needed for the cell to become infected; only the capsids enter the nucleus. b) the viral envelope is not required for infectivity, since the envelope does not enter the nucleus. c) only the genetic material of the virus is involved in the cell's infectivity, and is injected like the genome of a phage. d) the viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus.

A46-year-old man with a history of hypertension and hypercholesterolemia visits the physician for a routine followup. the patient's job involves a lot of travelling, and he admits to occasionally forgetting to take his medications with him when he travels. he complains of several episodes of chest pain in the past few months. the pain is sharp in nature, mainly over his lower chest and epigastrium, and tends to come on when walking. he believes these episodes are due to indigestion and has been taking antacids. there is a family history of heart disease, and his father died of a heart attack at age 48. on physical examination, his blood pressure is 150/80 mmhg and heart rate is 86/min. his lungs are clear to auscultation. cardiac auscultation reveals normal rate and rhythm, without rubs, gallops, or murmurs. there is no pedal oedema. he is sent for an exercise stress test. five minutes into the test, he develops st depression of 3mm in leads v1-v5. the st segment depression is greater than 0.12 seconds in duration and the stress test is stopped. which of the following is the most appropriate next step in management? - coronary angiography- holter monitor- no further tests are required- repeat stress test with thallium- upper gastrointestinal endoscopy
