A child has an avulsed (knocked-out) tooth. In which medium should the nurse instruct the parents to place the tooth for transport to the dentist?
A dry, clean jar.
Warm salt water.
Cold milk.
Cold water.
The Correct Answer is C
The correct answer is choice C.
Choice C rationale:
Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.
Choice A rationale:
Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.
Choice B rationale:
Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.
Choice D rationale:
Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.

Correct Answer is B
Explanation
The correct answer is choice B. Administer supplemental oxygen before and after suctioning.
Choice A rationale:
Expect symptoms of respiratory distress when suctioning. While respiratory distress can occur during and after suctioning, it is not the main nursing consideration. The primary goal is to minimize any potential complications and ensure the child's safety during the procedure, which can be achieved by following appropriate guidelines.
Choice B rationale:
Administer supplemental oxygen before and after suctioning. Correct Answer. Administering supplemental oxygen before and after suctioning is crucial to maintain adequate oxygenation during and after the procedure. Suctioning can temporarily decrease oxygen levels and cause desaturation, especially in a child who has undergone heart surgery. Providing supplemental oxygen helps prevent hypoxia and supports respiratory function.
Choice C rationale:
Perform suctioning at least every hour. Frequent suctioning at least every hour is not a standard nursing practice, especially for a child who has had heart surgery. Suctioning should only be performed as needed based on the child's clinical condition, and excessive suctioning can irritate the airway and lead to complications.
Choice D rationale:
Suction for no longer than 30 seconds at a time. While limiting the duration of suctioning is important to prevent hypoxia and trauma to the airway, the specific duration of 30 seconds is not a universal rule. Suctioning should be performed for the shortest effective duration to minimize the risk of complications, but the optimal time can vary based on the child's condition and the type of suctioning being used.
Correct Answer is D
Explanation
The correct answer is choice D. "Currant jelly" stools.
Choice A rationale:
Loose, foul-smelling stools are not characteristic of intussusception. Intussusception is a condition in which a part of the intestine invaginates into another part, causing obstruction. This obstruction often leads to "currant jelly" stools, which are composed of mucus, blood, and sloughed intestinal tissue. Loose stools might be associated with other gastrointestinal issues but are not a hallmark of intussusception.
Choice B rationale:
Ribbon-like stools are characteristic of intussusception. When a section of the intestine telescopes into another section, it can cause the stool to be squeezed into a ribbon-like shape as it passes through the narrowed portion. This description aligns with the pathophysiology of intussusception.
Choice C rationale:
Hard stools positive for guaiac indicate the presence of blood in the stool, but this finding is not specific to intussusception. Guaiac testing detects occult blood, which could be present in various gastrointestinal conditions, including bleeding ulcers or diverticulitis, and not exclusively in intussusception.
Choice D rationale:
"Currant jelly" stools are characteristic of intussusception. As mentioned earlier, these stools are the result of the obstruction and subsequent damage to the intestinal lining, leading to the presence of blood, mucus, and sloughed tissue. This description is a classic sign of intussusception and should raise suspicion for this condition.
