1. During the second week of hospitalization for intravenous antibiotic therapy, a 2-year-old toddler whose family is unable to visit often smiles easily, goes to all the nurses happily, and does not express interest in the parent when the parent does visit. The parent tells the nurse, 'I am pleased about the adjustment but somewhat concerned about my child’s reaction to me.' How should the nurse respond?
- A. The child is repressing feelings towards the parent.
- B. Routines have been established, and the child feels safe.
- C. The child has given up fighting and accepts the separation.
- D. Behavior has improved because the child feels better physically.
Correct answer: C
Rationale: The correct answer is C. The child's behavior of smiling easily, interacting happily with nurses, and showing disinterest in the parent when they visit indicates that the child has emotionally withdrawn and accepted the separation. This response suggests that the child may have given up fighting against the separation from the parent due to prolonged hospitalization. Choices A, B, and D are incorrect. Choice A about the child repressing feelings towards the parent is not supported by the scenario. Choice B about routines and feeling safe does not address the emotional aspect of the child's behavior. Choice D about improved behavior due to feeling better physically does not explain the emotional dynamics at play in the child's behavior.
2. The _____ is the inner layer of the embryo from which the lungs and digestive system develop.
- A. neural tube
- B. mesoderm
- C. endoderm
- D. umbilical cord
Correct answer: C
Rationale: The endoderm is the correct answer. It is the innermost layer of the embryo that gives rise to organs such as the lungs, digestive system, liver, and pancreas. The neural tube (Choice A) forms the brain and spinal cord, not the lungs or digestive system. Mesoderm (Choice B) develops into structures like muscles, bones, and circulatory system, not the lungs or digestive system. The umbilical cord (Choice D) serves as a connection between the embryo and the placenta, providing nutrients and oxygen, but it is not the layer from which lungs and digestive system develop.
3. When assessing a newborn infant with low set ears, short palpebral fissures, flat nasal bridge, and an indistinct philtrum, a priority maternal assessment by the nurse should be to ask about
- A. Alcohol use during pregnancy
- B. Usual nutritional intake
- C. Family genetic disorders
- D. Maternal and paternal ages
Correct answer: A
Rationale: The correct answer is A: Alcohol use during pregnancy. The physical features mentioned are indicative of fetal alcohol syndrome, a condition caused by maternal alcohol consumption during pregnancy. It is crucial for the nurse to inquire about alcohol use as it can help in diagnosing and managing the infant's condition. Choices B, C, and D are incorrect as they are not directly associated with the physical findings described in the newborn, which specifically point towards a potential history of alcohol exposure during pregnancy.
4. What is the purpose of amniocentesis?
- A. To induce abortion
- B. To detect genetic abnormalities in the fetus
- C. To determine the baby's gender
- D. To monitor fetal growth
Correct answer: B
Rationale: Amniocentesis is a diagnostic procedure used to detect genetic abnormalities in the fetus, such as chromosomal disorders like Down syndrome. It is not performed to induce abortion. The primary purpose of amniocentesis is to assess the genetic health of the fetus, not to determine the baby's gender (Choice C). While amniocentesis can provide information about the baby's health and development, it is not primarily used for monitoring fetal growth (Choice D). Therefore, the correct answer is B.
5. In what order should the PN implement these steps to provide wound care? (Place in correct order.)
- A. Don procedure gloves
- B. Remove the dressing
- C. Apply prescribed medications to the wound
- D. All of the Above
Correct answer: D
Rationale: The correct answer is 'D - All of the Above.' The PN should first don procedure gloves to maintain aseptic technique, then remove the dressing to assess the wound, and finally apply prescribed medications to the wound. This sequence ensures that non-sterile tasks like donning gloves are done before sterile tasks like applying medications, reducing the risk of wound contamination. Choices A, B, and C are all essential steps in providing effective wound care.
