within 24 hours after birth
A newborn develops physiologic jaundice, and the mother asks the nurse why this happened. Which response by the nurse would be most accurate? "We really don't know why jaundice develops in some babies and not in others. We just know how to treat it." "There is some type of blood incompatibility between you and your baby that's causing the problem." "Because his liver is a bit immature, the baby can't break down the bilirubin as fast as needed." "Your baby must have a blocked duct near his liver that's preventing the bilirubin from being excreted."
"Because his liver is a bit immature, the baby can't break down the bilirubin as fast as needed." The newborn has physiologic jaundice, which is related to decreased bilirubin conjugation. Newborns have relatively immature livers and cannot conjugate (break down) bilirubin as fast as needed. Bilirubin overproduction is responsible for causing jaundice associated with a blood incompatibility. Impaired bilirubin excretion, such as from an obstruction in the biliary tree, also can lead to jaundice. The causes of newborn jaundice are known; jaundice usually results from one of these three mechanisms.
The nurse is assessng a newborn male in the presence of the parents and notes that he has a hypospadias. How should the nurse respond when questioned by the parents as to what this means? "His testicles have not descended into the scrotal sac." "His urinary meatus in located on the under surface of the glans." "He has fluid in the scrotal sac." "He has normal male genitalia."
"His urinary meatus in located on the under surface of the glans." The term "hypospadias" refers to the urinary meatus being abnormally located on the ventral (under) surface of the glans. There are no special terms to indicate normal genitalia. Cryptorchidism refers to undescended testes. Hydrocele refers to the collection of fluid in the scrotal sac.

The nurse helps a breastfeeding mother change the diaper of her 16-hour-old newborn after the first bowel movement. The mother expresses concern because the large amount of thick, sticky stool is very dark green, almost black in color. She asks the nurse if something is wrong. The nurse should respond to this mother's concern by: 1. telling the mother not to worry because breastfed babies have this type of stool. 2. explaining to the mother that the stool is called meconium and is expected of all newborns for the first few bowel movements. 3. asking the mother what she ate at her last meal. 4. suggesting that the mother ask her pediatrician to explain newborn stool patterns to her.
2. explaining to the mother that the stool is called meconium and is expected of all newborns for the first few bowel movements.

The mother of a 2-day-old male has been informed that her child has sepsis. The mother is distraught and says, "I should have known that something was wrong. Why didn't I see that he was so sick?" The best reply is: A. "Newborns have immature immune function at birth, and illness is very hard to detect." B. "Your mothering skills will improve with time. You should take the newborn class." C. "Your baby didn't get enough active acquired immunity from you during the pregnancy." D. "The immunity your baby gets in utero doesn't start to function until he is 4 to 8 weeks of age."
A. "Newborns have immature immune function at birth, and illness is very hard to detect." The immune system of a newborn lacks response to pyrogens and presents a limited inflammatory response; thus, the signs and symptoms of infection are often subtle and nonspecific in the newborn. This response does not address the physiology of neonatal infection and is not therapeutic because it is blaming. The mother develops active acquired immunity, which is passed to the newborn transplacentally as passive acquired immunity. This immunity is to the illnesses and infections she has had or been immunized against. The passive acquired immunity a newborn receives from its mother is effective at birth and lasts from four weeks to eight months, depending on the specific antibody.
The parents of a newborn are receiving discharge teaching. The nurse explains that the infant should have several wet diapers per day. Which statement by the parents indicates that further education is necessary? A. "Our baby was born with kidneys that are too small." B. "A baby's kidneys don't concentrate urine well for several months." C. "Feeding our baby frequently will help the kidneys function." D. "Kidney function in an infant is very different from in an adult."
A. "Our baby was born with kidneys that are too small." Size of the kidneys is rarely an issue. Counting wet diapers indicates urine output in relation to fluid intake. Frequent feeding helps maintain the fluid volume. The ability to concentrate urine develops by 3-4 months of age. The inability to concentrate urine due to limited tubular reabsorption and lower glomerular filtration rate are the main differences between kidney function in a newborn and normal adult kidney function.
The home care nurse is examining a 3-day-old infant. The skin on the child's sternum is yellow when blanched with a finger. The parents ask the nurse why jaundice occurs. The best response from the nurse is: A. "The liver of an infant is not fully mature and doesn't conjugate the bilirubin for excretion." B. "The infant received too many red blood cells after delivery because the cord was not clamped immediately." C. "The yellow color of your baby's skin indicates that you are breastfeeding too often." D. "This is an abnormal finding related to your baby's bowels not excreting bilirubin as they should."
A. "The liver of an infant is not fully mature and doesn't conjugate the bilirubin for excretion." Physiologic jaundice is a common occurrence and peaks on day 3 or 4. It happens in part because of the RBC destruction that infants experience combined with liver immaturity, which leads to less efficient conjugation of bilirubin for excretion. Frequent feeding, therefore, will decrease jaundice. Bilirubin binds to the proteins in breast milk and formula for excretion through the bowels.
During a community health class, the nurse is educating prenatal patients and their partners about normal newborn behavior. Which attendee's statement indicates that teaching was effective? "I can expect that my newborn baby: A. "Will be able to hear very well immediately after she is born." B. "Should be trained to breastfeed by being encouraged to suck on a pacifier before feedings." C. "Will have difficulty seeing me close up in the hours right after delivery." D. "Should be discouraged form sucking on a pacifier if he is bottle feeding."
A. "Will be able to hear very well immediately after she is born." Newborns have very acute hearing immediately after birth. Pacifiers should be offered to breastfed infants only after breastfeeding is well established or during prolonged times away from the mother, or when stressful or painful procedures are required. The newborn is nearsighted and has best vision at a distance of 8 to 15 inches. For bottle-fed infants, there is no reason to discourage nonnutritive sucking with a pacifier.
1. New discoveries in molecular genetics will have the greatest effect on nursing practice in the area of: a. collection and use of health histories. b. counseling clients. c. identification of gene mutations. d. use of new therapies.
ANS: A The profession of nursing will be impacted by new discoveries in molecular genetics in the areas of education, practice, and public health debates. The practice arena impacts are collection and use of health histories, learning and applying innovative biotechnologies, prevention and health education roles, and administration of new therapies.
What would be a warning sign of ineffective adaptation to extrauterine life if noted when assessing a 24-hour-old breastfed newborn before discharge? A. Apical heart rate of 90 beats/min, slightly irregular, when awake and active B. Acrocyanosis C. Harlequin color sign D. Weight loss representing 5% of the newborn's birth weight
A. Apical heart rate of 90 beats/min, slightly irregular, when awake and active The heart rate of a newborn should range from 120 to 140 beats/min, especially when active. The rate should be regular with sharp, strong sounds. Acrocyanosis is a normal finding in a newborn at 24 hours of age. A harlequin sign is a normal finding related to the immature neurologic system of a newborn. A 5% weight loss is acceptable in the newborn.
The newborn at 24 hours of age has a red blood cell count of 5.4 million per ml. Which of the following entries would the nurse expect to find in the newborn's chart? A. Cord clamping delayed until pulsation ceased B. CBC drawn from the anterior surface of the left hand C. Placental abruption noted to be 80% at time of delivery D. Infant is breastfed 15-20 minutes every three hours
A. Cord clamping delayed until pulsation ceased Delayed cord clamping can cause an increase of RBC up to 61%, resulting in a slightly higher-than-average red blood cell count. Venous blood has lower red cell counts than do capillary blood samples. Maternal or fetal blood loss cause hypovolemia and low red blood cell counts (less than 5.2 million per ml). Breastfeeding does not impact red cell counts in the first day of life.
A nurse is counseling a client who is considering having genetic testing completed to determine whether she is a carrier of the gene linked to Huntingtons disease. What is the first step the nurse would take when assessing this client? a. Assess vital signs. b. Assess family history of this disorder. c. Assess clients past medical history. d. Assess current medications.
ANS: B Taking a family history is a useful place to begin when considering a genetic connection and prior to the onset of testing.
When reviewing laboratory results for a 1-day-old infant, the nurse notes that the infant's IgM antibodies are elevated. Which is the least likely cause of the infant's IgM antibody level elevation? A. Maternal-fetal transfer of IgM while in utero B. Placental leakage C. Intrauterine exposure to syphilis D. Intrauterine exposure to TORCH syndrome
A. Maternal-fetal transfer of IgM while in utero Because IgM does not normally cross the placenta, most or all of it is produced by the fetus beginning at 10 to 15 weeks' gestation. Elevated levels of IgM at birth may indicate placental leaks or, more commonly, antigenic stimulation in utero. Elevated levels of IgM at birth may indicate placental leaks. Elevations in IgM may be due to newborn exposure to an intrauterine infection such as syphilis. Elevations in IgM at birth may be due to newborn exposure to an intrauterine infection such as syphilis or TORCH syndrome (toxoplasmosis, rubella, cytomegalovirus, herpesvirus hominis type 2 infection).
A nurse is working as part of a genetic counseling team. Which of the following tasks would the nurse most likely perform? a) Complete a physical examination. b) Identify the client's support systems. c) Prepare a written summary for the client. d) Discuss the specific test findings.
Identify the client's support systems
A nurse caring for a newborn should be aware that the sensory system least mature at the time of birth is: A. Vision. B. Hearing. C. Smell. D. Taste.
A. Vision. The visual system continues to develop for the first 6 months. As soon as the amniotic fluid drains from the ear (minutes), the infant's hearing is similar to that of an adult. Newborns have a highly developed sense of smell. The newborn can distinguish and react to various tastes.
A nurse applies genetic and genomic knowledge when completing a client assessment by: a. Constructing a pedigree from a collected family history b. Identifying a client who may benefit from genetic counseling c. Referring a client to specialized genetic services d. Incorporating knowledge of genomic risk factors
ANS: A Constructing a pedigree from a collected family history demonstrates assessment in the nursing process. Identification is demonstrated by identifying a client who may benefit from genetic counseling. Referral is demonstrated by referring a client to specialized genetic services. Provision of education, care, and support is demonstrated by incorporating knowledge of genomic risk factors.
The Genetic Information Nondiscrimination Act (GINA): a. Protects individuals from discrimination based on their genetic information b. Allows health insurance companies to deny coverage for pre-existing conditions c. States employers may collect genetic information from employees as needed d. Requires employees to report genetic disorders to their employer
ANS: A GINA was designed to prohibit the improper use of genetic information in health insurance and employment. It protects individuals from discrimination based on their genetic information, prevents denial of coverage based solely on genetic predisposition to disease, and limits disclosure of genetic information.
The increasing knowledge about genetics and genomics will influence nursing practice by changing how: a. Nurses collect and use health histories b. Nursing students complete clinical experiences c. Referrals to other disciplines are made d. Ethical dilemmas are solved
ANS: A Genetics and genomics will change future practice in several areas including: how students are educated, how nurses collect and use health histories, how nurses learn and apply innovative biotechnology, how prevention and health education is provided, administration of new therapies, and public health debates.
A nurse working in the 1970s would have applied genetic concepts by: a. Providing genetic counseling to those with genetic disorders b. Educating clients about using genetic testing for risk identification c. Explaining the purposes of the Human Genome Project to clients d. Facilitating referrals for specialized genetic services for clients
ANS: A In the 1970s, nurses working in genetics provided genetic counseling to persons with genetic diseases or risk factors for such disorders. The other activities performed by the nurse did not occur until the 1990s.
A nurse uses the Codes of Ethics developed by the International Council of Nurses and the American Nurses Association when: a. Providing confidential genetic testing for a client b. Advocating for the inclusion of genetic content in a nursing curriculum c. Considering the pros and cons of an ethical dilemma d. Becoming competent in genomics
ANS: A The Codes of Ethics include in this mandate the right that people have to seek and receive genomic heath care that is nondiscriminatory, confidential, private, and that enables those served to make informed decisions.
The blueprint or code that is used to construct other components of cells is called the: a. DNA b. Gene c. Chromosome d. Base
ANS: A The DNA is the chemical inside the nucleus of the cell that has the genetic instructions for making living organisms. This can be compared to a blueprint or code that is used to construct other components of cells.
When a nurse understands the significant impact that genetic testing can have on an individual and family, the nurse is meeting a competency identified by the: a. National Coalition of Health Professional Education in Genetics (NCHPEG) b. Centers for Disease Control and Prevention c. American Nurses Association d. International Council of Nurses
ANS: A The NCHPEG identifies one competency of health care professionals as being able to understand that health-related genetic information can have social and psychological implications for individuals and families.
According to the CDCs Genomic competencies for the public health workforce, all public health workers should be able to (select all that apply): a. Demonstrate basic knowledge of the role that genomics play in disorders. b. Make appropriate referrals to those with more genomic experience. c. Counsel individuals about their genetic susceptibility for particular disorders. d. Recommend appropriate genetic screening tests for clients.
ANS: A, B The CDCs Genomic competencies for the public health workforce apply to all public health professionals. All public health workers should demonstrate basic knowledge and be able to make appropriate referrals. The other statements would not be true of competencies of all public health workers.
When delivering safe and effective nursing care, the nurse must consider the significance of which factor(s) in the development of disease? Select all that apply. a. Genetics b. Lifestyle c. Environment d. Technology
ANS: A, B, C The knowledge of human genetics can improve the safety, quality, and effectiveness of care for clients. It is important for nurses to understand the predisposition to disease as well as the impact of behavior and social conditions on overall community health and well-being. Many genetic disorders have an environmental link.
1. Genes that carry genetic instructions for making living organisms are subject to alterations in: (Select all that apply.) a. changes in chromosomal structure. b. changes in deoxyribonucleic acid. c. changes in ribonucleic acid. d. sequences of bases.
ANS: A, B, C, D Alterations in the usual sequence of bases [adenine (A), guanine (G), cytosine (C), and thymine (T)] that form a gene, changes in DNA or chromosomal structures are called mutations. A large number of agents are known to cause mutations. Despite three billion DNA base pairs that must be replicated in each cell division and the large number of mutagens we are exposed to, DNA replication is quite accurate because of the mechanism known as DNA repair that corrects 99.9% of initial errors.
A public health nurse is demonstrating one of the minimum competencies set forth by the National Coalition of Health Professional Education in Genetics (NCHPEG) when: a. Organizing a meeting to discuss the care of cystic fibrosis clients b. Making a referral to a genetics specialist c. Advocating for legislation to support stem cell research d. Educating a client about the results of genetic testing
ANS: B The minimum competencies for health care professionals set forth by NCHPEG are: be able to examine competence of practice, understand the social and psychological implications of health-related genetic information, and know how and when to make referrals to a genetics professional. Making a referral is the only example that is described in these competencies.
The aim of genomic medicine is a) improving predictions about individuals' susceptibility to diseases. b) cure of disease. c) cloning. d) reproduction.
Improving predictions about individuals' susceptibility to diseases
2. The National Coalition of Health Professional Education in Genetics (NCHPEG) created a red-flag tool for determining risk in closely related individuals for the most common diseases that includes: (Select all that apply.) a. close biologic relationship between parents. b. condition occurs in the gender that is least expected. c. ethnic predisposition to certain genetic disorders. d. multiple affected family members. e. onset at an earlier or later than expected age
ANS: A, B, C, D The genetic red flags developed by the NCHPEG provide an excellent tool to determine if an individual or family might be at risk. The primary red flag for the most common diseases is a large number of affected relatives who are closely related. Some of the red flags are family history of multiple affected family members with the same or related disorders, which may or may not follow an identifiable pattern in the family; onset at an early age; condition occurs in the gender that is least expected to have it; disease occurs in the absence of known risk factors; ethnic predisposition to certain genetic disorders; and a close biological relationship between parents.
A nurse is counseling a client who has just learned that she is a carrier of the BRCA-2 gene. What are potential reactions by this client? (Select all that apply) a. Feelings of guilt b. Fear of loss of insurance coverage c. Feelings of anxiety d. Fear for children
ANS: A, C, D Feelings of guilt, anxiety, and fear for future susceptibility for children are all potential reactions this client may have. The Genetic Information Nondiscrimination Act (GINA) protects clients from losing insurance benefits based upon genetic information.
4. A young female client is concerned about her risk for developing ovarian cancer and needs information that might affect her health decisions. She requests that her elderly grandmother be tested for genetic mutations. One significant challenge faced by a family member in responding to such a request is: a. anxiety about the future. b. carrier guilt. c. decreased quality of life. d. fear of blood draws.
ANS: B Genomics has influenced the availability of genetic tests which has implications for families. Individuals, families, and communities need to understand the purpose, limitations, and potential benefits and risks of a test before submitting samples for analysis. Genetic testing is now used to predict the development of genetic disorders, screening populations, confirming diagnoses, prenatal testing, and DNA testing to develop and apply individualized medical treatment.
6. A middle-aged woman, with a history of breast and ovarian cancer in her family, is concerned that a positive finding for BRACA2 gene may result in loss of her insurance coverage. The nurse should discuss protections under: a. the Affordable Care Act. b. the Genetic Information Nondiscrimination Act (GINA). c. Healthy People 2020. d. the Human Genome Project.
ANS: B The GINA of 2009 protects the public from genetic discrimination by employers or insurers. The act prevents group health plans and health insurers from denying coverage to a healthy individual or charging higher premiums based solely on genetic predisposition to disease. The legislation also prohibits employers from using an individual's genetic information when hiring, firing, or making job placement or promotion decisions.
3. The overarching themes conceptualized in the vision for the Human Genome Project embrace the relationship of genomes to: a. biology, chemistry, and medicine. b. biology, health, and society. c. ethics, medicine, and heredity. d. medicine, technology, and ethics.
ANS: B The stated goals of the Human Genome Project were determining the sequence of the three billion chemical pairs that make up human DNA; storing this information in databases; improving tools for data analysis; transferring related technologies to the private sector; and addressing the ethical, legal, and social issues (ELSI) that may arise from the genome mapping project completed in 2003 that identified 25,000 genes in human DNA.
2. In the late 1950s, Down syndrome was discovered to be caused by an extra copy of chromosome 21. This early breakthrough best describes: a. double-helix structure. b. genetics. c. genomics. d. mutation carrier.
ANS: B The term genetics is used to mean the study of the function and effect of single genes that are inherited by children from their parents—in other words, the cause of certain diseases, the genetic link.
When a nurse learns more about the Human Genome Project to better counsel families about the process of genetic testing, the nurse is learning about: a. Genetics b. Genomics c. Genes d. Genetic susceptibility
ANS: B Genomics refers to the study of individual genes to understand the structure of the genome, including the mapping of genes and sequencing the DNA.
The father of genetics is: a. Charles Darwin b. Gregor Mendel c. James Watson d. Francis Galton
ANS: B Gregor Mendel is considered to be the father of genetics. Charles Darwin expounded on theories of evolution. Francis Galton performed family studies using twins to understand the influence of heredity on various human characteristics. James Watson was the co-discoverer of DNA.
When a nurse considers that clients may not want to have genetic testing done because of the impact that it may have on future life decisions, the nurse is incorporating genetics/genomics into practice using: a. Assessment b. Identification c. Referral d. Provision of education, care, and support
ANS: B One of the ways that a nurse uses identification is by identifying ethical, cultural, and societal issues related to genetic and genomic information and technologies. Assessment is not being performed here because the nurse is not assessing a particular clients needs or history. Referral is not taking place, nor is education, care, or support of a patient.
A nurse is counseling a client whose genetic test results show a genetic susceptibility for breast cancer. The most appropriate statement by the nurse would be: a. You should discuss hormone replacement therapy with your physician. b. You are at an increased risk to develop breast cancer. c. You should have a bilateral mastectomy as soon as possible. d. You should tell all of your siblings and children to get tested.
ANS: B Persons with a genetic susceptibility are at increased risk for developing the disease. Although the client may choose to have a bilateral mastectomy and recommend genetic testing to other family members, the most important thing to relay to the client is that having a genetic susceptibility does not mean that one will automatically have the disease.
Which type of body tissue have the highest risk for cancer development
Any tissue that retains the ability to divide
What are the scores for an Apgar score?
Appearance 0=blue 1=pink with blue extremities 2=completely pink Pulse 0=none 1= <100 BPM 2= >100 BPM Grimace 0=none 1=grimacing 2=vigorous cry Activity 0=flaccid 1=some flexion 2=well flexed Respiratory 0=Absent 1=Slow 2=Crying with normal RR
The best response from a nurse when counseling a client who is considering purchasing a genetic testing kit from a vendor advertised on the Internet would be: a. It is illegal to purchase genetic testing kits from Internet vendors. b. It will be important to follow up with a health care provider after receiving your results. c. Many times online vendors experience inaccuracies with their results. d. Internet vendors use the latest technology to perform these tests.
ANS: B The most important aspect of genetic testing is the counseling that occurs with the testing. Purchasing genetic testing kits on the Internet makes it easy for the public to access, but leaves a health care professional out of the testing process. Meeting with a health care professional is important to counsel a client about the implications and indications for such testing.
3. A client's concern about hereditary cancer syndrome can be influenced by the limitations of current testing methods and factors related to: (Select all that apply.) a. absolute risk. b. adoption. c. family size. d. family interest. e. GINA.
ANS: B, C Current methods of testing do not detect all of the mutations that can occur in some diseases including hereditary cancer syndrome-related genes. If a mutation is detected, it does not confirm an absolute risk of cancer but a need for high-risk management. Additionally, an inherited syndrome may not be evident for someone from a small family; someone who is adopted; or someone who is not informed about their family's history of disease or cause of death. Most hereditary cancer syndromes are inherited in an autosomal dominant pattern with variable expression and incomplete penetrance (mutation in one member of the gene pair). Both men and women carry, pass on to children, and inherit these mutations. For mutation carriers, the hereditary cancer syndrome can be mild or more severe. Whether cancer ever develops, the site at which it develops, or the seriousness of the cancer can vary among different people with the same mutation, even within the same family.
7. A nurse in a community health clinic reviews a client's health history and includes a family health history across three generations, noting any diseases with a genetic basis. The nurse is detecting or defining risk in low-risk groups for potential referral for diagnostic testing. This is an example of: a. genetic testing. b. primary prevention. c. secondary prevention. d. tertiary prevention
ANS: C When a nurse reviews the health history, the nurse observes for any disease that may have a genetic basis and if found, immediately refers the person or family to the appropriate health care provider. The goal of screening is to detect or define risk in low-risk groups and identify those people who should have diagnostic testing.
Which question would be the most appropriate for the nurse to ask when eliciting information about a clients genetic history? a. Have any of your family members ever completed genetic testing? b. Do any of your family members have a genetic disorder? c. What medical problems have your parents and grandparents experienced? d. What environmental exposures have you had?
ANS: C A clients family medical history is important to obtain in order to consider the clients potential risk for genetic diseases and disorders. The best way to obtain this information is to ask an open-ended question about past medical history of parents and grandparents.
. Which statement regarding mutations is true? a. Mutations in the DNA sequence occur on a regular basis. b. Mutagens are a result of a mutation. c. Environmental factors can be linked to many mutations. d. Spontaneous mutations occur because of environmental exposure.
ANS: C A large number of agents are known to cause mutations. These mutations are attributed to known environmental causes. DNA replication is very accurate, thus, mutations do not occur on a regular basis. Mutagens are the factors that cause mutations. Spontaneous mutations occur naturally during DNA replication.
Which role of the nurse will be most important in the future practice of providing genomic nursing care? a. Direct caregiver b. Educator c. Advocate d. Referral agent
ANS: C Although the nurse will use all of these roles when providing genomic nursing care, the most important role will be that of advocate. Nurses will increasingly provide guidance on policy discussions and ethical issues that relate to confidentiality, privacy, and commercialization. This is the nursing role of advocate.
One of the main goals of the Human Genome Project was: a. Providing physicians with a national database for information related to genetic disorders b. Developing new medications that can be used in genetics research c. Addressing ethical, legal, and social issues related to this research d. Improving the ability to accurately test for genetic disorders
ANS: C The goals of the Human Genome Project were to determine the sequences of the base pairs in human DNA; improve tools for data analysis; transfer related technologies to the private sector; and address the ethical, legal, and social issues that may arise.
5. Cleft lip and/or palate, a common congenital malformation, is often inherited and influenced by environmental factors, therefore it is referred to as a(n): a. extra chromosome expression. b. gene mutation. c. lifetime exposure phenomenon. d. multifactorial disease.
ANS: D Multifactorial diseases or those caused by gene and environment interaction influence disease risk, health conditions, and the therapies used to treat disease. Multifactorial disorders tend to occur in families and include such common inherited congenital malformations as cleft lip and palate, neural tube defects, and congenital heart disease.
Which statement would be most appropriate for the nurse to make when assisting a family in compiling a family health history? a. When you have completed this history, it will not need to be updated. b. Looking back at two generations of biological relatives will be sufficient. c. The purpose of completing a family history is to decrease genetic susceptibility. d. A family history is a useful tool when considering your future health risks.
ANS: D A family history is a useful tool to help families know about their health risks and prevent disease in themselves and their close relatives. It is recommended that families develop a three generation history and update it on a regular basis. Completion of a family history will not decrease genetic susceptibility; rather it will make families more aware of what that susceptibility may be.
What should an infants mean arterial pressure be?
Approximately equal to the age in gestational weeks
Julia age 32 is BRCA1 +, which is known to greatly increase the risk for breast and ovarian CA. She was tested because her mom who had ovarian CA was BRCA1 + . Julia has decided to have both her ovaries removed because she believes that in her family, being BRCA1+ increases the risk for ovarian CA only. How should a genetic counselor respond
Clarify that a BRCA1 mutation does not preferentially express ovarian CA over breast CAin any given family
While collecting a medical history, a client reports having a family history positive for Huntingtons disease. However, the client states he does not want to have genetic testing performed. The nurse recognizes that one reason a client may refuse genetic testing is because of the: a. Impact it may have on obtaining health insurance in the future b. Legal consequences that may result c. Inaccuracy of the results that are obtained d. Decreased quality of life that may occur if the results are positive
ANS: D Barriers to genetic testing are: some individuals do not have an insurance carrier that reimburses for genetic testing, a high-deductible insurance policy, and feelings that testing may decrease the quality of life and increase anxiety for the future if the results were positive. Others may also feel guilty about passing along a disease to children and grandchildren.
An example of a multifactorial disorder is: a. Measles b. Hepatitis B c. Eczema d. Type I diabetes
ANS: D Disorders that are influenced by multiple factors including genetics/genomics, environment, lifestyle, and other factors are considered to be multifactorial.
A nurse implements the principles of the Personalized Health Care Initiative in practice by: a. Educating clients that multiple factors influence the development of disease b. Counseling clients about the results of genetic testing c. Lobbying for legislation to support genetic research d. Protecting clients from discrimination based on the results of genetic testing
ANS: D The goals of the Personal Health Care Initiative are to link clinical and genomic information to support personalized health care, protect individuals from discrimination-based or unauthorized use of genetic information, ensure the accuracy and clinical validity of genetic tests performed for medical application purposes, and develop common policies for access to genomic databases for federally-sponsored programs.
Which factor would demonstrate physiologic respiratory adaptation to extrauterine life in a newborn infant? Rapid respirations following a cesarean birth to eliminate fetal fluids Abrupt temperature change upon delivery, causing a cry Increase in oxygen levels and decrease in CO2 levels, stimulating respirations Taking a breath within 3 minutes of delivery with stimulation
Abrupt temperature change upon delivery, causing a cry Respiratory adaptation following birth is seen in an infant that responds with a strong cry following thermal changes, such as those the newborn experiences going from the warm uterus to the cold outside air. The first breath should occur within the first few moments after birth, not after 3 minutes. The rapid decrease in oxygen and increase in the CO2 levels, not the reverse, serves as stimulation for respirations. Tachypnea following a cesarean birth does not demonstrate respiratory adaptation but may indicate fluid retention and complications.
Which of the following physical assessment findings indicates a need for further evaluation? Hypertonia Absence of the rooting reflex Brisk knee jerk Plantar flexion
Absence of the rooting reflex Rationale: Absence or delayed disappearance of reflexes will always be a concern and a reason to refer for developmental screening. Newborns tend to have more hypertonia than hypotonia. Hypotonia would be a definite need for a referral. Brisk knee jerk and plantar flexion should be found upon exam of the newborn. Evaluation; Physiological Integrity; Analysis
During pregnancy the fetus has protection through moms vaccinations which form antibodies. This is what type of immunity
Active acquired immunity
Activity decreases, decreases HR and RR, deep sleep 2-4 hours, difficult to arouse, no interest in feeding, likely not to void or stool, 30 minutes after delivery
Activity to sleep phase
What target cultural population is a priority for the nurse to educate about prevention of hypertension? a) African Americans b) Hispanics c) Native Americans d) Italian Americans
African Americans
The nurse encourages bonding when a baby is in which stage of the sleep-wake cycle?
Alert
A patient born at 27 weeks gestation develops grunting, nasal flaring, and decreased oxygenation. Based on the patient's gestational age, there is more than likely a deficiency in surfactant. Surfactant is critical for: Development of the bronchi or bronchioles in the lungs. Absorption and reabsorption of additional lung secretions. Preventing the exchange of oxygen and carbon dioxide. Alveolar stability.
Alveolar stability. Rationale: Surfactant prevents the alveoli from completely collapsing with each expiration, thus promoting lung expansion. Other options are important for inspiratory and expiratory cycles, but are not pertinent in the discussion of functioning alveoli of the lung. Diagnosis; Physiological Integrity; Analysis
Birth does what to systemic vascular resistance and what to pulmonary resistance?
Increases systemic vascular resistance and decreases pulmonary vascular resistance
The nurse is teaching new parents how to dress their newborn. Which statements indicate that teaching has been effective? (Select all that apply.) A. "We should make sure that we keep our home air-conditioned so the baby doesn't overheat." B. "It is important that we dry the baby off as soon as we give him a bath or shampoo his hair." C. "When we change the baby's diaper, we should change any wet clothing or blankets, too." D. "If the baby's body temperature gets too low, he will warm himself up without any shivering." E. "Our baby will have a much faster rate of breathing if he is not dressed warmly enough."
B. "It is important that we dry the baby off as soon as we give him a bath or shampoo his hair." C. "When we change the baby's diaper, we should change any wet clothing or blankets, too." D. "If the baby's body temperature gets too low, he will warm himself up without any shivering." E. "Our baby will have a much faster rate of breathing if he is not dressed warmly enough." Babies need to be kept warm. Cold ambient temperatures will increase the oxygen consumption of a newborn and can lead to respiratory distress. Drying a wet baby prevents evaporation, one mechanism of heat loss. Changing wet clothing or blankets immediately prevents evaporation, one mechanism of heat loss. Non-shivering thermogenesis is the mechanism used by newborns to warm themselves. A neonate with a low body temperature will increase oxygen consumption, which can lead to respiratory distress.
An examiner who discovers unequal movement or uneven gluteal skinfolds during the Ortolani maneuver: A. Tells the parents that one leg may be longer than the other, but they will equal out by the time the infant is walking. B. Alerts the physician that the infant has a dislocated hip. C. Informs the parents and physician that molding has not taken place. D. Suggests that if the condition does not change, surgery to correct vision problems might be needed.
B. Alerts the physician that the infant has a dislocated hip. This is an inappropriate statement that may result in unnecessary anxiety for the new parents. The Ortolani maneuver is a technique for checking hip integrity. Unequal movement suggests that the hip is dislocated. The physician should be notified. Molding refers to movement of the cranial bones and has nothing to do with the infant's hips. The Ortolani maneuver is not a technique used to evaluate visual acuity in the newborn. This maneuver checks hip integrity.
The nurse helps a breastfeeding mother change the diaper of her 16-hour-old newborn after the first bowel movement. The mother expresses concern since the large amount of thick, sticky stool is very dark green, almost black in color. She asks the nurse if something is wrong. The nurse should respond to this mother's concern by: A. Telling the mother not to worry since all breastfed babies have this type of stool. B. Explaining to the mother that the stool is called meconium and is expected of all newborns for the first few bowel movements. C. Asking the mother what she ate at her last meal. D. Suggesting that the mother ask her pediatrician to explain newborn stool patterns to her.
B. Explaining to the mother that the stool is called meconium and is expected of all newborns for the first few bowel movements. This type of stool is the first stool that all newborns, not just breastfed babies, have. At this early age this type of stool (meconium) is typical of both bottle-fed and breastfed newborns. The mother's nutritional intake is not responsible for the appearance of meconium stool. The nurse is fully capable of and responsible for teaching a new mother about the characteristics of her newborn, including expected stool patterns.
The nurse notes that, when placed on the scale, the newborn immediately abducts and extends the arms, and the fingers fan out with the thumb and forefinger forming a "C." This response is known as a: A. Tonic neck reflex. B. Moro reflex. C. Cremasteric reflex. D. Babinski reflex.
B. Moro reflex. Tonic neck reflex refers to the "fencing posture" a newborn assumes when supine and turns the head to the side. These actions show the Moro reflex. The cremasteric reflex refers to retraction of testes when chilled. The Babinski reflex refers to the flaring of the toes when the sole is stroked.
The newborn's nurse should alert the health care provider when which newborn reflex assessment findings are seen? (Select all that apply.) A. Newborn turns head toward stimulus when eliciting rooting reflex. B. Newborn's fingers fan out when palmar reflex checked. C. Newborn forces tongue outward when tongue touched. D. Newborn exhibits symmetric abduction and extension of arms, and fingers form "C" when Moro reflex elicited. E. Newborn's toes hyperextend with dorsiflexion of big toe when sole of foot stroked upward along lateral aspect.
B. Newborn's fingers fan out when palmar reflex checked. The baby's fingers should curl around the examiner's fingers when eliciting the palmar reflex. When eliciting rooting reflex, the characteristic response is for the baby to turn head toward stimulus and open mouth. Extrusion is elicited by touching tongue, and newborn's tongue is forced outward. The newborn should elicit symmetric abduction and extension of the arms and fingers form a "C" with the Moro reflex. The Babinski reflex is elicited by stroking upward along the lateral aspect on the sole of the feet. The expected response is hyperextension of the toes with dorsiflexion of the big toe.
A newborn male, estimated to be 39 weeks of gestation, would exhibit: A. Extended posture when at rest. B. Testes descended into scrotum. C. Abundant lanugo over his entire body. D. Ability to move his elbow past his sternum.
B. Testes descended into scrotum. The newborn's good muscle tone will result in a more flexed posture when at rest. A full-term male infant will have both testes in his scrotum and rugae on his scrotum. The newborn will exhibit only a moderate amount of lanugo, usually on his shoulders and back. The newborn would have the inability to move his elbow past midline.
Which intervention would be the best way for the nurse to prevent heat loss in a newborn while bathing? Limit the bathing time to 5 minutes. Bathe the baby in water between 90 and 93 degrees. Bathe the baby under a radiant warmer. Postpone breastfeeding until after the initial bath.
Bathe the baby under a radiant warmer. Bathing a newborn under a radiant warmer helps to prevent heat loss. To minimize the effects of cold stress during the bath, the nurse should also prewarm blankets, dry the child completely to prevent heat loss from evaporation, encourage skin-to-skin contact with the mother, promote early breastfeeding, used heated and humidified oxygen, and defer bathing until the newborn is medically stable. Limiting the length of time spent bathing the baby is secondary to maintaining the baby's body temperature. Having warm water is also important but is irrelevant if the baby is not kept warm under a warmer.
A nurse working as part of a genetics counseling team is preparing a presentation for a career day discussion at a local college of nursing. When describing the genomic framework for nursing, which of the following would the nurse include as being most important? a) Experiencing first-hand providing care for a wide range of genetic conditions b) Having a thorough understanding of the various technologies available c) Being keenly aware of one's own attitudes and assumptions about genetics and genomics d) Obtaining in-depth knowledge about the variety of cultural beliefs related to the causes of illness
Being keenly aware of one's own attitudes and assumptions about genetics and genomics
How are malignant rumors different from benign tumors
Benign tumors have totally normal features, and malignant tumors have totally abnormal features
What are mongolian spots?
Bluish discoloration over buttocks and base of spine. Benign and will usually fade in 1-2 years. Document this to avoid later confusion with bruises.
The nurse needs to draw blood via heel stick for a newborn screening examination. How can the nurse use understanding of the newborn's heat production physiology to promote blood collection?
By applying a warm pack to the heel before attempting to draw blood
The nurse manager of the neonatal intensive care unit is preparing a handout for parents of ill newborns. Which statement should the nurse include? A. Newborns can eliminate excess fluid as quickly as an adult. B. The kidneys are fully functional by 30 weeks' gestation. C. Neonates have a tendency to become dehydrated. D. Sugar is rarely present in the urine of a newborn.
C. Neonates have a tendency to become dehydrated. Neonates cannot concentrate their urine or pull water back into the vascular volume, and thus can become dehydrated easily. Newborns have difficulty eliminating excess fluid because of their relatively low glomerular filtration rate. Full nephron function doesn't develop until 34-36 weeks. Tubular reabsorption of glucose, sodium, amino acids, and bicarbonate is limited in newborns. Glucosuria therefore develops.
A new grandfather is marveling over his 12-hour-old newborn grandson. Which statement indicates that the grandfather needs additional education? A. "I can't believe he can already digest fats, carbohydrates, and proteins." B. "It is amazing that his whole digestive tract moves things along at birth." C. "Incredibly, his stomach capacity is already a cupful when he was born." D. "He will lose some weight but then miraculously regain it by about 10 days."
C. "Incredibly, his stomach capacity is already a cupful when he was born." A newborn's stomach capacity is only 20-40 ml; overfeeding of bottle-fed infants tends to cause regurgitation and abdominal discomfort, exhibited by crying. At birth, neonates can digest fats, simple carbohydrates, and proteins. Gastric emptying and intestinal peristalsis occur during in utero life; the first bowel movement usually occurs in the first day of life. Neonates lose 5-10 % of their birth weight in the first days after life, especially if they are breastfed. They should have regained the lost weight and should be back to their birth weight by 10 days of age.
The new father asks the nurse to describe what his baby will experience while sleeping and awake. The best response is: A. "Babies have several sleep and alert states. Keep watching and you'll notice them." B. "You may have noticed that your child was in an alert awake state for an hour after his birth." C. "Newborns have two stages of sleep: deep or quiet sleep and rapid eye movement sleep." D. "Birth is hard work for babies; it takes them a week or two to recover and become more awake."
C. "Newborns have two stages of sleep: deep or quiet sleep and rapid eye movement sleep." This statement is true. Teaching the parents how to detect the two sleep stages helps them tune in to their infant's behavioral states. Although it is true that babies have several sleep and alert states, the wording of this response is condescending and not therapeutic. This is not the best response. Although this statement is true, it does not respond to the father's question about sleeping now. Recovery from the birth process only takes a day or two. During that time, feedings should take place when the baby is in an alert state.
A telephone triage nurse gets a call from a postpartum patient who is concerned about jaundice. The patient's newborn is 37 hours old. What data should the nurse gather first? A. Stool characteristics B. Fluid intake C. Skin color D. Bilirubin level
C. Skin color Yellow coloration of the skin and sclera is a sign of physiologic jaundice that appears after the first 24 hours postnatally. Inspection of the skin would be the first step in assessing for jaundice. The stool characteristic of green coloration indicates excretion of bilirubin. Inadequate fluid intake can predispose an infant toward becoming jaundiced and is best determined by the number of wet diapers per day. Skin color begins to appear yellow once the serum levels of bilirubin are about 4-6 mg/dL.
The nurse is planning an educational presentation on hyperbilirubinemia for nursery nurses. Which statement is most important to include in the presentation? A. Conjugated bilirubin is eliminated in the conjugated state. B. Unconjugated bilirubin is neurotoxic and cannot cross the placenta. C. Total bilirubin is the sum of the direct and indirect levels. D. Antibiotics decrease the incidence of hyperbilirubinemia.
C. Total bilirubin is the sum of the direct and indirect levels. This is true. Conjugated bilirubin is also referred to as direct, while unconjugated bilirubin is also referred to as indirect. Conjugated bilirubin can be transformed back into unconjugated bilirubin prior to excretion by β-glucuronidase enzyme if gut bacteria have not transformed it into urobilinogen. Unconjugated bilirubin is neurotoxic but crosses the placenta during fetal life for the maternal GI system to conjugate and excrete. Because of the role of gut bacteria in converting conjugated bilirubin into urobilinogen, neonates who have been administered antibiotics have an increased incidence of hyperbilirubinemia.
Which type of genetic test would be used to detect the possibility of Down syndrome? a) DNA analysis b) Complete blood count (CBC) c) Chromosomal analysis d) Hemoglobin electrophoresis

Cystic fibrosis
Which assessment findings indicate the newborn is cold stressed and burning brown fat to produce heat? (Select all that apply.)
Hypoglycemia Metabolic acidosis Respiratory distress
During a post conference, nursing students are simulating physical assessment of the newborn using a model. Throughout the simulated assessment, students describe each of their actions. Which nursing student's statement indicates the need for further teaching? A. "I measured the newborn's blood pressure using the Doppler technique." B. "I auscultated the infant's heart tones for one minute." C. "I palpated peripheral pulses in all the newborn's extremities." D. "I obtained the infant's heart rate by observing the cardiac monitor."
D. "I obtained the infant's heart rate by observing the cardiac monitor." Physical assessment of the newborn's heart rate requires auscultation of the apical pulse for a full minute. The measurement of blood pressure is best accomplished by using the Doppler technique with a size- and weight-appropriate cuff over the brachial artery. Apical pulse rates should be obtained by auscultation for a full minute, preferably when the newborn is asleep. Peripheral pulses of all extremities should also be evaluated to detect any inequalities or unusual characteristics.
A postpartum patient calls the nursery to report that her 3-day-old newborn has passed a bright green stool. The nurse's best response is: A. "Take your newborn to the pediatrician." B. "There may be a possible food allergy." C. "Your newborn has diarrhea." D. "This is a normal occurrence."
D. "This is a normal occurrence." By the third day of life, the newborn's stools appear brown to green in color. It is not necessary for the patient to take her newborn to the pediatrician. The green color of stool is not due to food allergies. The green color of stool is not characterized as diarrhea, but is a transitional stool that consists of part meconium and part fecal material.
The nurse is reviewing charts of newborns. Which infant requires immediate intervention? A. 24-hour-old term male with total bilirubin level of 2.0 B. 3-day-old term bottle-fed female with bilirubin of 11.0 C. 2-week-old post-term breastfed male with bilirubin of 10.0 D. 12-hour-old preterm female exhibiting icterus and lethargy
D. 12-hour-old preterm female exhibiting icterus and lethargy Jaundice is an indication of hyperbilirubinemia and is not an expected finding in the first day of life. Lethargy can be a sign of kernicterus developing. Preterm infants are more likely to develop jaundice. Total bilirubin levels under 3.0 are expected in the first 24 hours of life. Physiologic jaundice peaks between days 3 and 5; a total bilirubin level of 11.0 is not treated with phototherapy, regardless of feeding method. Breast milk jaundice peaks at 2-3 weeks of age and commonly presents with a total bilirubin level of 5.0-10.0.
The nurse is assessing a newborn at 1 hour of age. Which finding requires an immediate intervention? A. Respiratory rate 60, crackles present bilaterally B. Pulse rate 145, systolic murmur heard C. Mean blood pressure 55 mm Hg D. Pauses in respiration lasting 30 seconds
D. Pauses in respiration lasting 30 seconds Pauses in respirations greater than 20 seconds are considered episodes of apnea and require further intervention. Respiratory rate is normal; crackles are commonly heard in the first few hours after birth as the infant reabsorbs the fluid in the lungs present at birth. This pulse rate is normal. Systolic murmurs are very unlikely to indicate serious pathology and are usually caused by incomplete closure of the ductus arteriosus or foramen ovale. This is a normal blood pressure finding in an infant at 1 hour of life.
When weighing a newborn, the nurse should: A. Leave its diaper on for comfort. B. Place a sterile scale paper on the scale for infection control. C. Keep hand on the newborn's abdomen for safety. D. Weigh the newborn at the same time each day for accuracy.
D. Weigh the newborn at the same time each day for accuracy. The baby should be weighed without a diaper or clothes. Clean scale paper is acceptable; it does not need to be sterile. The nurse's hand should be above, not on, the abdomen for safety. Weighing a newborn at the same time each day allows for accurate weights.

A routine hematocrit level is drawn on a newborn immediately after delivery and is found to be 68%. What may have contributed to this abnormally high hematocrit level? Delayed cord clamping Leukocytosis Hypovolemia Congenital heart defect
Delayed cord clamping Correct answer: Blood volume increases by approximately 50% with delayed cord clamping; this increase is reflected by a rise in hematocrit level to about 65%. Congenital heart defects, leukocytosis, and hypovolemia are not related at all to high hematocrit levels. Diagnosis; Physiological Integrity; Analysis

When do the vast majority of trisomies occur?
During oogenesis
How does early feeding lower the newborn's risk of developing jaundice?
Early feeding promotes peristalsis and passing of meconium. Meconium is high in unconjugated bilirubin, so the longer it is in the intestines, the more bilirubin is absorbed back into circulation
The nurse reviews the laboratory results of a 1-hour-old newborn. Which finding does the nurse need to report to the provider immediately?
Elevated bilirubin

The nurse would least likely be responsible for which of the following? a) Advocating for confidentiality of the results b) Obtaining the client's family history c) Educating the client about the testing procedures d) Informing the client about the testing results
Informing the client about the testing results
When does the mucosal barrier mature in infants and what is the significance?
It is mature by 4-6 months. Before this, the barrier is very permeable and can allow bacteria and other harmful substances into systemic circulation
A nurse does an initial assessment on a newborn and notes a pulsation over the anterior fontanelle that corresponds with the newborn's heart rate. How would the nurse interpret this? This finding is normal if the pulsation can also be palpated in the posterior fontanelle. If the fontanelle feels full, then this is normal. This is an abnormal finding and needs to be reported immediately. It is normal to feel pulsations that correlate with the newborn's heart rate over the anterior fontanelle.
It is normal to feel pulsations that correlate with the newborn's heart rate over the anterior fontanelle.
What should be told to the pt who have been found to have genetic mutation that increase the risk of colon cancer and says he does not want any of his family to know about their result
It is not required that you tell anyone about this Renault, However because your sibling and children may also be at risk for common cancer, you should think about how this information might help them
The nursing instructor is teaching a class on the physiologic properities involved with the birthing process. The instructor determines the session is successful when the students correctly match surfactant with which function? It expands the lungs with breaths. It keeps alveoli from collapsing with breaths. It allows oxygen to move in the lungs. It removes fluid from the lungs.
It keeps alveoli from collapsing with breaths.
Best description of the genetic contribution to onset of autism
Known causes of autism spectrum include copy number variants and chromosomal problems
Which objective data best indicates that the ductus arteriosus of a newborn has not closed? Temperature instability ranging from 36.5°C to 38.5°C. Rapid heart rates between 180 and 220 beats per minute. Labile oxygen saturations with occasional apnea/bradycardia spells. Low blood pressure and blood pressure means.
Labile oxygen saturations with occasional apnea/bradycardia spells. Correct answer: Closing of the ductus arteriosus does not directly affect heart rate, blood pressure, or body temperature. It does affect shunting of the blood, causing unstable oxygen saturations and resulting in possible apneic and bradycardic episodes. Assessment; Physiological Integrity; Analysis

After teaching nursing students about autosomal-dominant and autosomal-recessive inherited disorders, the instructor determines that the teaching was successful when the class identifies which of the following as true about autosomal-dominant inherited conditions? a) The percentage of people with a trait who manifest it is variable. b) The severity of the manifestations often varies in degrees. c) Horizontal transmission is more commonly seen in families. d) Males and females are equally affected by this pattern of inheritance.
Males and females are equally affected by this pattern of inheritance.
What is the end result of hypothermia in infants?
Metabolic acidosis
To create a neutral thermal environment for a newborn immediately after delivery, the nurse should consider: Minimal stimulation, and place under the radiant warmer bed. Place newborn with extremities extended and relaxed, and place hat over newborn's head. Deep suction every hour while under the radiant warmer bed. Place newborn with extremities extended and relaxed under the radiant warmer bed.
Minimal stimulation, and place under the radiant warmer bed. Correct answer: A newborn should never be suctioned hourly. Minimal stimulation is suggested to conserve heat and energy (perform grouped cares). The newborn should be placed in a flexed position to decrease exposed surface tension, decreasing amount of heat lost. Implementation; Health Promotion and Maintenance; Application
The nurse is assisting with the admission of a newborn boy to the nursery. The nurse notes what appears to be bruising on the left upper outer thigh of htis dark-skinned infant. Which documentation should the nurse provide? Mongolian spot noted on left upper outer thigh Harlequin sign noted on left upper outer thigh Birth trauma noted on left upper outer thigh Mottling noted on left upper outer thigh
Mongolian spot noted on left upper outer thigh A mongolian spot is bluish-black areas of discoloration on the back and buttocks or extremities of dark-skinned newborns. The Harlequin sign refers to the dilation of blood vessels on only one side of the body, giving the newborn the appearance of wearing a clown suit. Mottling occurs when the lips, hands, and feet appear blue from immature peripheral circulation. Birth trauma is a possibility, however, there would be notations of an incident and the possibly other injuries would be noted.
The nurse is conducting an assessment on a newborn and witnesses a startled response with the extension of the arms and legs. The nurse should document this as which response? Tonic neck Fencing Moro Rooting
Moro The Moro reflex is also known as the startle reflex. When the infant is startled, they extend their arms and legs away from the body. The fencing reflex is also called the tonic neck reflex and is a total body assessment. The rooting reflex assesses the infant's ability to "look" for food.
A nurse is preparing a presentation for a local community group about familial Alzheimer's disease. As part of the presentation, the nurse is planning to discuss the possible genetic basis for this condition.

A breast-feeding patient is attempting to soothe a 2-day-old crying newborn. The patient finds a pacifier and places it in the newborn's mouth. What is the nurse's best response? Coating the pacifier with honey will make the pacifier more desirable to the infant. Pacifiers are discouraged completely because of difficulties noted weaning infants after one year of life. Discuss different styles and shapes of pacifiers with the patient to determine which pacifier works best for the infant. Pacifiers are discouraged due to a phenomenon called nipple confusion.
Pacifiers are discouraged due to a phenomenon called nipple confusion. Rationale: Pacifiers should be offered to breast-fed infants only after breast-feeding is well established. If the pacifier is offered too soon, a phenomenon called nipple confusion may occur in the breast-fed infant. Never coat the pacifier with sugary substances. Pacifiers are encouraged once breast-feeding is well established. Planning; Health Promotion and Maintenance; Application
