Question 1 of 5
At 10 weeks gestation, a primigravida asks the nurse what is occurring developmentally with her baby. Which response by the nurse is correct?
Correct Answer: C
Rationale: The correct answer is C: The kidneys are making urine. At 10 weeks gestation, the baby's kidneys start to form and become functional, producing urine. This is a crucial milestone in the baby's development as it signifies the beginning of the urinary system functioning. The other answer choices are incorrect because:
A) The skin is still thin and translucent at this stage, fat formation occurs later in pregnancy.
B) The eyelids typically remain fused shut until around 27 weeks gestation.
D) The heart begins to form early in pregnancy, usually by 4 weeks gestation.
Question 2 of 5
A client asks the nurse about the benefits of breastfeeding. Which response by the nurse provides the most accurate information?
Correct Answer: C
Rationale: The correct answer is C: Breast milk is easier to digest than formula. Breast milk is specifically designed to be easily digested by infants, leading to less digestive issues compared to formula. This is important for the baby's overall health and well-being.
Choice A is incorrect because weight loss varies among individuals and should not be the primary reason for breastfeeding.
Choice B is incorrect as breast milk contains the right balance of nutrients but not necessarily a greater amount of protein compared to formula.
Choice D is incorrect as breastfeeding is not a reliable method of contraception.
Question 3 of 5
A women in her first trimester contracts rubella. How is the fetus likely to be affected?
Correct Answer: B
Rationale: The correct answer is B: Heart defects and cataracts. Rubella infection in the first trimester can lead to congenital rubella syndrome, causing heart defects and cataracts in the fetus. Rubella can disrupt fetal development during this critical period.
Choices A, C, and D do not directly correlate with the effects of rubella infection in the first trimester. Reproductive and urinary defects are not commonly associated with rubella. Spinal cord and skeletal defects are more commonly linked to neural tube defects or genetic conditions. Polydactyly and club feet are not typically caused by rubella infection during pregnancy.
Question 4 of 5
Which is a major difference in the clinical manifestation of adolescents with anorexia nervosa compared to bulimia?
Correct Answer: C
Rationale: The major difference between adolescents with anorexia nervosa and those with bulimia is body image distortion. Clients with anorexia see themselves as being overweight no matter how underweight they become. Clients with bulimia see their weight realistically but have psychological problems that manifest in an eating disorder. Both disorders may involve binge eating and purging, but body image perception is a distinguishing factor.
Question 5 of 5
A nurse monitors fetal well-being by means of an external monitor. At the peak of the contractions, the fetal heart rate has repeatedly dropped 30 beats/min below the baseline. Late decelerations are suspected and the nurse notifies the physician. Which is the rationale for this action?
Correct Answer: D
Rationale: The correct answer is D. Late decelerations are associated with uteroplacental insufficiency, leading to fetal hypoxia. This occurs due to poor oxygen exchange at the placenta during contractions, resulting in a delayed recovery of the fetal heart rate after the contraction peaks. Repeated late decelerations indicate ongoing fetal distress and the need for immediate intervention to prevent further compromise.
Choices A and B are incorrect as they describe different types of decelerations.
Choice C is incorrect as late decelerations are indeed associated with hypoxia. However, they are related to uteroplacental insufficiency rather than the strength of maternal contractions.
Choice D provides the most accurate explanation of late decelerations and their significance in indicating fetal distress.
