An important role of the nurse in ambulatory settings and schools is the identification of communicable diseases for treatment and the prevention of spread. What is an important component related to the first period of the contagiousness of disease?

Correct Answer: C

Rationale: The prodromal period is the interval between the early manifestations of the disease and the time when the overt clinical syndrome is evident. Most communicable diseases are contagious during this time. Identifying the prodromal stage is crucial for early intervention and preventing the spread of the disease. While the source and causative agent are important aspects of disease control, recognizing the early signs in the prodromal stage allows the nurse to take timely actions. Constitutional symptoms occur during the active disease phase, indicating that the child has already been contagious, and early intervention opportunities may have passed.

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.

Correct Answer: D

Rationale: The priority action for the nurse when the apnea monitor alarm sounds on a neonate is to assess the infant for color and the presence of respirations. This initial assessment helps determine the infant's respiratory status and the need for immediate intervention. Providing tactile stimulation or administering oxygen should only be done after assessing the infant's respiratory status. Investigating possible causes of a false alarm comes after ensuring the infant's well-being through the initial assessment.
