A nurse is caring for an adolescent who states, "I failed my math exam because the teacher doesn't like athletes." The nurse should identify that the adolescent is using which of the following defense mechanisms?

Choice A rationale:

Grapes are a choking hazard for toddlers due to their small size and round shape. Young children can easily choke on grapes if they are not cut into smaller pieces or grapes are not adequately supervised during consumption. Educating parents and caregivers about cutting grapes into smaller, more manageable pieces is crucial to prevent choking incidents.

Choice B rationale:

Oranges (choice B) are generally not considered a high choking hazard for toddlers. However, parents and caregivers should still exercise caution and cut oranges into small, manageable pieces to reduce the risk of choking.

Choice C rationale:

Potatoes (choice C) can be a choking hazard for toddlers if not prepared and served appropriately. It is essential to cut potatoes into small, soft pieces and ensure that toddlers are supervised during mealtime to prevent choking incidents.

Choice D rationale:

Corn (choice D) can also pose a choking hazard for toddlers, especially if served on the cob. To minimize the risk, parents and caregivers should cut corn into small, bite-sized pieces or remove it from the cob before serving to young children.

Choice A rationale:

Increasing the client's intake of oral fluids may not address the underlying issue of crackles in the bases of the lungs, shortness of breath, and a respiratory rate of 24/min. This client likely has fluid accumulation in the lungs, and simply increasing fluid intake could exacerbate the problem. It's important to assess and manage the client's fluid balance carefully.

Choice B rationale:

Instructing the client to cough every 4 hours may not be sufficient for managing the client's symptoms, especially if there is fluid in the lungs. Coughing alone may not adequately clear the airways. More intensive interventions are needed.

Choice C rationale:

The correct action is to "Maintain the client in high-Fowler's position." High-Fowler's position helps improve lung expansion and oxygenation by allowing the client to sit up at an angle, which reduces pressure on the diaphragm and improves lung mechanics. This position can help alleviate symptoms such as crackles and shortness of breath in clients with heart failure.

Choice D rationale:

Encouraging the client to ambulate to loosen secretions may not be appropriate in this case. Ambulation is generally encouraged for clients with adequate oxygenation and mobility. If the client has severe respiratory distress, it's crucial to address that issue first before considering ambulation.
