Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?
- A. skin
- B. adipose tissue
- C. skeletal muscle
- D. myocardium
Correct Answer: D
Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.

According to Erikson, which developmental task is a toddler confronting when they develop 'a will of his own' and 'acts as if he can control others'?
- A. Trust versus mistrust
- B. Autonomy versus doubt and shame
- C. Initiative versus guilt
- D. Industry versus inferiority
Correct Answer: B
Rationale: According to Erikson, the correct developmental task for a toddler who has developed 'a will of his own' and 'acts as if he can control others' is Autonomy versus doubt and shame. Toddlers at this stage are asserting their wills and realizing they can control others, which is part of developing autonomy. However, they may also experience doubt and shame if their assertiveness is met with disapproval. Trust versus mistrust is the developmental task of the infant, where the main focus is on developing trust in the caregiver. Initiative versus guilt is the developmental task of the preschool-age child, emphasizing the balance between taking initiative and feeling guilty. Industry versus inferiority is the developmental task of the school-age child, focusing on competence and self-esteem.
A nurse in a day-care setting is planning play activities for 2- and 3-year-old children. Which toys are most appropriate for these activities?
- A. Finger paints and card games
- B. Blocks and push-pull toys
- C. Videos and cutting-and-pasting toys
- D. Simple board games and puzzles
Correct Answer: B
Rationale: The most appropriate toys for 2- and 3-year-old children in a day-care setting are blocks and push-pull toys. Toddlers enjoy objects of different textures like clay, sand, finger paints, and bubbles, as well as push-pull toys, large balls, and sand and water play. They also like activities such as blocks, painting, coloring with large crayons, large puzzles, and playing with trucks or dolls. Finger paints and card games may be more suitable for older children. Videos and cutting-and-pasting toys are generally more appropriate for preschoolers. Blocks and push-pull toys are beneficial for young children as they help in developing fine motor skills, hand-eye coordination, spatial awareness, and creativity. These toys also encourage imaginative play and problem-solving, making them ideal choices for toddlers.
A nurse helps a young adult conduct a personal lifestyle assessment. The nurse carefully reviews the assessment with the young adult for which reason?
- A. Young adults may ignore physical symptoms and postpone seeking health care
- B. Young adults are unable to afford health insurance
- C. Young adults are at risk for a serious illness
- D. Young adults are exposed to hazardous substances
Correct Answer: A
Rationale: The corrected answer is A: Young adults may ignore physical symptoms and postpone seeking health care. Young adults are usually quite active, experience severe illnesses less commonly than members of older age groups, tend to ignore physical symptoms, and often postpone seeking health care. Clients in this developmental stage may benefit from a personal lifestyle assessment to identify habits that increase the risk for various chronic diseases. Choice B is incorrect because the ability to afford health insurance is not the primary reason for conducting a personal lifestyle assessment. Choice C is incorrect because young adults are not inherently at higher risk for serious illness compared to other age groups. Choice D is incorrect because exposure to hazardous substances is not the main focus when conducting a personal lifestyle assessment.
During a well-baby examination, the nurse measures the head circumference, and it is the same as the chest circumference. On the basis of this measurement, what action should the nurse take?
- A. Document these measurements in the infant's health care record.
- B. Tell the mother that the infant is growing faster than expected.
- C. Suggest to the health care provider that a skull x-ray be performed.
- D. Report the presence of hydrocephalus to the health care provider.
Correct Answer: A
Rationale: The head circumference growth rate during the first year is approximately 0.4 inches (1 cm) per month. By 10 to 12 months of age, the infant's head and chest circumferences are equal. In this case, where the head circumference matches the chest circumference, it is a normal finding in infants around 10-12 months. Therefore, the most appropriate action is to document these measurements in the infant's health care record. Suspecting hydrocephalus or suggesting a skull x-ray would be premature and not indicated based on this measurement. Similarly, telling the mother that the infant is growing faster than expected is not accurate and could cause unnecessary concern.
What is one of the main goals of Healthy People 2010?
- A. reduction of health care costs
- B. elimination of health disparities
- C. investigation of substance abuse
- D. determination of an acceptable morbidity rate
Correct Answer: C
Rationale: The main goal of Healthy People 2010 is the elimination of health disparities among the U.S. population. This initiative outlines specific objectives to improve the overall health of Americans by addressing disparities in health outcomes. Choice A, reduction of health care costs, is not the primary goal of Healthy People 2010, although it may be a beneficial outcome. Choice C, investigation of substance abuse, is not a main goal of Healthy People 2010; while substance abuse may be a factor in health disparities, the primary focus is on broader disparities. Choice D, determination of an acceptable morbidity rate, is not the main focus of Healthy People 2010; instead, it aims to address health disparities in different population groups.
