Correct Answer: C

Rationale: The blood glucose level for a newborn infant should remain greater than 40 mg/dL to prevent permanent brain damage. When dealing with low blood glucose in a newborn, the most appropriate initial action is to contact the registered nurse. The nurse will obtain prescriptions regarding feeding the infant with low blood glucose and follow agency policies on feeding infants in such conditions. It is common practice to feed the infant if the glucose level is 40 mg/dL or less. Asking the registered nurse to draw another blood sample in 2 hours and repeating the test is not the most appropriate immediate action, as timely intervention is crucial in this situation. Contacting the healthcare provider may cause unnecessary delays since the registered nurse is usually the first point of contact for immediate actions in this scenario. Documenting the results in the newborn's medical record is essential, but it is not the initial step in managing low blood glucose in a newborn.

Correct Answer: B

Rationale: A rubella titer of less than 1:8 indicates that the client is not immune to rubella. In such cases, retesting will be necessary during the pregnancy. If the client is found to be non-immune, rubella immunization is required post-delivery. Therefore, choices A, C, and D are incorrect. Choice A suggests exposure, which cannot be confirmed by the titer result. Choice C wrongly implies that the client has not developed immunity, which is not accurate. Choice D is incorrect as the titer result is not within the normal immune range.

Correct Answer: D

Rationale: The correct answer is 'Absence of accelerations after fetal movement.' In a nonreactive (nonreassuring) stress test, the monitor recording would not show accelerations after fetal movement within a 40-minute period. This absence of accelerations indicates a nonreactive result. Choices A, B, and C describe different patterns of fetal heart rate accelerations that are not indicative of a nonreactive result in a nonstress test, making them incorrect. Choice A describes the characteristics of a reactive (reassuring) result, where there should be at least two fetal heart accelerations within a 20-minute period, peaking at least 15 beats/min above the baseline, and lasting 15 seconds from baseline to baseline. Choice B incorrectly states 'Accelerations without fetal movement,' which is contradictory. Choice C describes an acceleration response to fetal movement, which does not signify a nonreactive result.

Correct Answer: A

Rationale: When a nurse notes accelerations from the baseline rate of the fetal heart rate, particularly when they occur with fetal movement, it is considered a reassuring sign. This indicates a healthy response to fetal activity. Reassuring signs in FHR monitoring include an average rate between 120 and 160 beats/min at term, a regular rhythm with slight fluctuations, accelerations from the baseline rate (often associated with fetal movement), and the absence of decreases from the baseline rate. Choices B, C, and D are incorrect because accelerations in FHR with fetal movement are not indicative of the need to contact the physician, fetal distress, or a nonreassuring sign. These signs would typically be associated with other abnormal FHR patterns that would warrant further assessment and intervention.

Correct Answer: A

Rationale: When preparing the physical environment for an interview with a client, it is crucial to ensure the client's comfort. Setting the room temperature at a comfortable level is essential for the client's well-being. Additionally, providing privacy, sufficient lighting, and removing distractions are crucial factors. It is recommended to maintain a distance of around 4 to 5 feet between the client and the nurse. Seating should be arranged so that the client and nurse are at eye level to facilitate effective communication and prevent barriers. Placing a chair across from the nurse's desk may create a physical barrier, positioning the client to face a strong light can be uncomfortable and distracting, and setting up seating so that the client and nurse are not at eye level may impede effective communication.
