Correct Answer: B

Rationale: An apical heart rate of 130/min is within the expected range for a newborn. It is not necessary to seek verification from another nurse, call the provider for further assessment, or prepare for NICU transport based on this heart rate. Documenting the heart rate as an expected finding is the appropriate action in this situation as it falls within the normal range for a newborn's heart rate.

Correct Answer: C

Rationale: An elevated temperature in a woman with ruptured membranes may indicate infection. Assessing the odor of the amniotic fluid can help determine if chorioamnionitis (an infection of the amniotic fluid) is present. This assessment is crucial to guide further interventions and management of the client's condition. Options A, B, and D are incorrect. Rechecking the client's temperature in 4 hours does not address the immediate concern of potential infection. Administering glucocorticoids intramuscularly is not indicated based solely on an elevated temperature. Preparing the client for an emergency cesarean section is premature and not supported by the information provided.

Correct Answer: A

Rationale: Vitamin K is typically administered in the vastus lateralis muscle of a newborn to prevent bleeding disorders. The vastus lateralis muscle is the preferred site for IM injections in infants due to its size and accessibility, allowing for easy and safe administration. The ventrogluteal and dorsogluteal sites are more commonly used in adults due to better muscle mass and less risk of injury to nearby structures. The deltoid muscle is typically used for older children and adults for IM injections, as it is a well-developed muscle suitable for injections in these populations.

Correct Answer: B

Rationale: The basal body temperature should be taken every morning before arising as it provides the most accurate reading. This time ensures consistency and eliminates variations that may occur throughout the day due to activities or environmental factors. Choice A is incorrect because ovulation can vary among individuals, and checking temperature on specific days may not align with the actual ovulation day. Choice C is incorrect as there is no direct correlation between intercourse and basal body temperature. Choice D is incorrect because taking the temperature before going to bed does not provide a consistent baseline reading.

Correct Answer: A

Rationale: Painless red vaginal bleeding is a hallmark sign of placenta previa. In this condition, the placenta partially or completely covers the cervical opening, leading to painless, bright red bleeding due to the separation of the placenta from the uterine wall. Other types of bleeding, such as those associated with abdominal pain or mucus passage, are more indicative of conditions like placental abruption rather than placenta previa. Therefore, choices B, C, and D are incorrect as they describe findings more consistent with placental abruption rather than placenta previa.
