A nurse is assessing a day-old infant for jaundice. Which of the following is the best method for this?

Correct Answer: A

Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.

Correct Answer: D

Rationale: The correct answer is D: Using the deltoid muscle for administration. Administering parenteral iron in the deltoid muscle is not recommended due to the risk of irritation and pain. The Z-track method (choice A) is preferred to prevent staining and irritation of the skin when administering irritating medications like iron. Using an air bubble (choice B) to avoid withdrawing medication into subcutaneous tissue is a common practice to ensure accurate administration. Not massaging the injection site (choice C) is also a standard practice to prevent potential irritation or bleeding at the injection site.

Correct Answer: C

Rationale: The Apgar score is based on five components: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the infant has a heart rate over 100 (2 points), is crying (2 points indicating good respiratory effort), resists the catheter (2 points for good reflex irritability), but has acrocyanosis (partial point deduction of 1). Thus, the Apgar score at one minute after birth would be 8. Choice A is incorrect as the given signs indicate a higher score. Choice B is incorrect as the signs described support a score above 6. Choice D is incorrect as it represents a perfect score which is not the case here due to acrocyanosis.

Correct Answer: B

Rationale: Orthodox Jews follow dietary laws (Kashrut) that prohibit mixing meat and dairy products in the same meal. This restriction is known as 'not mixing milk and meat.' Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because being an Orthodox Jew does not mean they can eat any food unless it is Yom Kippur, avoid meat on Ash Wednesday, or are necessarily vegetarian.

Correct Answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.
