What time frame has the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) and American College of Obstetricians and Gynecologists recommended that pregnant adolescents and women who are not protected against pertussis receive the tetanus, diphtheria, and pertussis (Tdap) vaccine?

Correct Answer: A

Rationale: The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) and American College of Obstetricians and Gynecologists recommend that pregnant adolescents and women without protection against pertussis should receive the Tdap vaccine ideally between 27 and 36 weeks of gestation or postpartum before discharge from the hospital. This timeframe allows for the development of antibodies in the mother to protect her and provide passive immunity to the infant. Administering the vaccine during the first trimester (Choice D) is not recommended as the optimal time is between 27 and 36 weeks. Choice B, during the first prenatal visit, is too early for optimal protection, and Choice C, 24 hours prior to delivery, does not provide enough time for the vaccine to be effective before birth.

Correct Answer: B

Rationale: A neonate normally loses about 10% of the birth weight by age 3 to 4 days. The birth weight is usually regained by the 10th day of life. In this case, the weight loss from 3400 g to 3147 g is within the expected range. Therefore, the most appropriate action is to explain to the mother that this weight loss is within normal limits. Choice A is incorrect because supplemental feedings of formula are not indicated for this expected weight loss in a breastfed newborn. Choice C is incorrect as there is no evidence to suggest excessive weight loss at this point. Choice D is unnecessary at this stage and may not align with the current situation of normal weight loss post-birth.

Correct Answer: D

Rationale: In newborns, intramuscular vitamin K is traditionally administered into the vastus lateralis muscle. This site is preferred due to its large muscle mass and accessibility. The dorsogluteal site is not recommended for newborns due to the risk of injury to the sciatic nerve. The deltoid site is also not recommended for newborns. The rectus femoris muscle is not commonly used for intramuscular injections in newborns.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid using any latex product.' In the case of a suspected latex allergy, it is crucial to prevent exposure to latex products to avoid allergic reactions. Choice B is incorrect because there are no truly non-allergenic latex products. Choice C is irrelevant to the situation described in the question, as the child does not have asthma. Choice D is also incorrect because desensitization is not an immediate option for managing a suspected latex allergy.

Correct Answer: C

Rationale: Hypertonic solutions can damage tissues if they leak from the vein due to infiltration. It is crucial to monitor for this complication to prevent severe tissue damage. Infiltration is not solely related to the activity level of VLBW infants; it can occur due to various reasons such as vein condition, catheter placement, and fluid type. Continuous infusion pumps may not always detect infiltration, as they typically alarm for pressure changes but not all infiltration instances. Checking the infusion site regularly, preferably hourly, is essential to prevent complications like tissue damage from extravasations, fluid overload, and dehydration.
