1. Following delivery, the nurse places the newborn under a radiant heat warmer. Which of the following is this action used to prevent?
- A. Cold stress
- B. Hyperthermia
- C. Dehydration
- D. Hypoxia
Correct answer: A
Rationale: Placing the newborn under a radiant heat warmer is used to prevent cold stress. Cold stress in newborns can lead to increased oxygen consumption and energy expenditure as the body tries to maintain its temperature, potentially resulting in hypoglycemia and metabolic acidosis if not addressed. The radiant warmer helps maintain the infant's body temperature, reducing the risk of cold stress and its complications. Choices B, C, and D are incorrect because the primary purpose of using a radiant warmer in this scenario is to prevent cold stress specifically, not hyperthermia, dehydration, or hypoxia.
2. What is the nurse's next action after a laboring client's membranes have just ruptured?
- A. Assess fetal heart rate pattern
- B. Monitor uterine contractions
- C. Administer oxygen
- D. Prepare for delivery
Correct answer: A
Rationale: After a laboring client's membranes have ruptured, the nurse's immediate priority is to assess the fetal heart rate pattern. This assessment is crucial to ensure the fetus is not in distress, especially to rule out umbilical cord compression that could affect blood flow to the fetus. While monitoring uterine contractions is important, assessing the fetal heart rate takes precedence in this situation as it directly reflects the fetus's well-being. Administering oxygen may be necessary later depending on the fetal status, and preparing for delivery should only occur if the assessment indicates fetal distress or other complications. Therefore, the correct next action for the nurse is to assess the fetal heart rate pattern.
3. A nurse is assessing a newborn and notes that the infant has yellow-tinged skin. Which of the following is the priority nursing action?
- A. Assess the infant's bilirubin levels
- B. Initiate phototherapy
- C. Monitor the infant's temperature
- D. Encourage breastfeeding
Correct answer: A
Rationale: Yellow-tinged skin (jaundice) in a newborn can indicate hyperbilirubinemia. The priority action is to assess the infant's bilirubin levels to determine the severity of the jaundice and the need for further interventions, such as phototherapy. Initiating phototherapy (choice B) is premature without knowing the actual bilirubin levels. Monitoring the infant's temperature (choice C) is important but not the priority in this situation. Encouraging breastfeeding (choice D) is beneficial but not the priority when dealing with jaundice in a newborn.
4. A client who has been prescribed oral contraception receives education from a nurse. Which of the following client statements indicates a need for further education?
- A. If I miss one pill, I'll take it as soon as possible
- B. If I miss two pills, I'll double up for two days
- C. If I miss three pills, I'll double up each day until back on schedule
- D. I'll use an alternative form of contraception if I miss more than two pills
Correct answer: C
Rationale: The correct course of action after missing oral contraceptive pills depends on how many pills are missed. If three pills are missed, the client should not 'double up' but rather follow the manufacturer's instructions and use an alternative form of contraception until the next cycle. Taking too many pills at once increases the risk of side effects without restoring contraceptive protection. Choices A, B, and D demonstrate understanding of the correct actions to take after missing a pill or two, emphasizing the importance of not doubling up but following specific guidelines to maintain effectiveness and safety.
5. A nurse is providing education to a client in the first trimester of pregnancy. What information should the nurse include regarding the cause of indigestion and heartburn?
- A. Estrogen causes increased appetite
- B. Progesterone causes relaxation of the cardiac sphincter allowing acid to reflux
- C. HCG hormone leads to increased gastric acidity
- D. The uterus compresses the stomach early in pregnancy
Correct answer: B
Rationale: The correct answer is B. Progesterone causes relaxation of the smooth muscles in the body, including the cardiac sphincter. This relaxation allows stomach acid to reflux into the esophagus, leading to heartburn during pregnancy. Choices A, C, and D are incorrect because they do not directly relate to the physiological mechanism that causes heartburn during pregnancy. Estrogen causing increased appetite (Choice A) is not directly linked to heartburn. HCG hormone increasing gastric acidity (Choice C) is not the primary cause of heartburn during pregnancy. The uterus compressing the stomach early in pregnancy (Choice D) may contribute to feelings of fullness or bloating but is not the main cause of heartburn.
