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: C

Rationale: The indirect Coombs test is performed to detect Rh-positive antibodies in the mother's blood. In cases where the mother is Rh-negative and the baby is Rh-positive, the mother may develop antibodies against the baby's blood cells, which can lead to hemolytic disease of the newborn. Choice A is incorrect because kernicterus is a complication of severe jaundice, not directly assessed by the indirect Coombs test. Choice B is incorrect as the test aims to detect Rh-positive antibodies, not Rh-negative antibodies in the newborn's blood. Choice D is incorrect as the test is focused on detecting antibodies in the mother's blood, not the newborn's.

Correct Answer: A

Rationale: The correct answer is A: Respiratory distress. Assessing for respiratory distress is the priority when evaluating a newborn after a cesarean delivery. Newborns born via cesarean section are at higher risk for respiratory complications, making it crucial to monitor their breathing and ensure proper oxygenation immediately after birth. Choice B, hypothermia, is important too but assessing breathing takes precedence to ensure adequate oxygen supply. Choices C and D, accidental lacerations and acrocyanosis, are not the immediate priorities following a cesarean delivery.

Correct Answer: B

Rationale: After an amniotomy, the priority nursing action is to assess the fetal heart rate pattern. This is crucial to monitor for any signs of fetal distress, as changes in the fetal heart rate could indicate potential complications related to the procedure. Observing the color and consistency of the fluid (Choice A) is important but not the priority over assessing fetal well-being. Assessing the client's temperature (Choice C) and evaluating the client for chills and increased uterine tenderness (Choice D) are not immediate priorities following an amniotomy.

Correct Answer: D

Rationale: The correct sequence of maternal changes during pregnancy is as follows: Amenorrhea (absence of menstrual periods), Goodell's sign (softening of the cervix), Quickening (first fetal movements felt by the mother), and Lightening (baby descending into the pelvis). These changes occur at different stages of pregnancy and are important indicators of fetal development and maternal adaptation. Choice A is correct as it is the initial change indicating possible pregnancy. Choices B, C, and D follow in the correct order of occurrence during pregnancy. Choices B, C, and D are incorrect as they do not follow the correct sequence of maternal changes.
