A client arrives at the emergency department with chest pain after taking sildenafil.
Based on the client's history, which medication should the nurse withhold?

Choice A rationale:

The client being the oldest of their siblings is not a contributing factor related to the development of conduct disorder. Family dynamics such as birth order may have some influence on personality traits, but they are not a primary factor in the development of conduct disorder.

Choice B rationale:

The fact that the client's father lives in the client's home is a family dynamic, but it does not necessarily contribute to the development of conduct disorder. Other factors related to parenting style, communication, and family interactions play a more significant role in the development of conduct disorder.

Choice C rationale:

The client's mother having asthma is a medical condition and not a family dynamic that directly contributes to the development of conduct disorder. Conduct disorder is more closely associated with social, environmental, and psychological factors.

Choice D rationale:

The presence of several siblings in the family dynamic can contribute to the development of conduct disorder. Increased family size can lead to competition for attention and resources, which may affect the child's behavior and interactions. Sibling relationships and family dynamics are crucial in shaping a child's behavior and psychological well-being.

Choice A rationale:

Nosocomial transmission in the medical area. Rationale: Nosocomial transmission refers to infections that are acquired in healthcare settings. While it's essential for healthcare professionals to be aware of this risk, the client's presentation of diarrhea in a hurricane disaster area is more likely due to environmental factors rather than hospital-acquired infection.

Choice B rationale:

Food contamination from floodwaters. Rationale: In the aftermath of a hurricane, floodwaters can carry contaminants and pathogens, leading to food contamination. This is a significant concern, and the nurse should educate the client about the potential risks associated with consuming food exposed to floodwaters. However, the primary source of contamination for diarrhea is typically waterborne pathogens, which is addressed in choice C.

Choice C rationale:

Drinking water contaminated by sewage. Rationale: During natural disasters like hurricanes, sewage systems can become compromised, leading to the contamination of drinking water sources. This contamination poses a significant risk for diarrheal illnesses, as sewage often contains harmful pathogens. Therefore, the nurse should consider this as the most probable source of the client's exposure.

Choice D rationale:

Close living quarters at evacuation centers. Rationale: Close living quarters in evacuation centers can contribute to the spread of infectious diseases, including diarrheal illnesses. However, in this scenario, the client's chief complaint is diarrhea, and the nurse should prioritize investigating potential sources of waterborne contamination, as this aligns more closely with the client's symptoms.
