ATI Pediatric Medications Test

Correct Answer: C

Rationale: Typhoid fever is primarily spread through contaminated food and water, usually due to poor sanitation practices. The bacteria responsible for typhoid fever, Salmonella Typhi, is typically found in food or water contaminated by the feces of an infected person. Contaminated air is not a significant mode of transmission for typhoid fever, making choice A incorrect. While waterborne transmission can occur, it is through contaminated water rather than specifically mineral water, making choice B incorrect. Therefore, the correct answer is C, as contaminated food and water are the main sources of transmission for typhoid fever.

Correct Answer: C

Rationale: Chest pain is a common symptom seen in patients with pneumococcal pneumonia. It can result from inflammation of the pleura or irritation of the diaphragm due to the infection. While cough and fever are also common symptoms, chest pain is particularly significant in pneumonia cases as it can be a distressing symptom for the patient and may indicate complications or severity of the infection. Bulging fontanel, on the other hand, is more indicative of conditions affecting infants and is not typically associated with pneumococcal pneumonia in a 12-year-old boy.

Correct Answer: C

Rationale: Aortic stenosis is a condition characterized by the narrowing of the aortic valve, leading to reduced blood flow from the heart to the body. This narrowing restricts the amount of oxygenated blood that can reach various tissues, including muscles. As a result, individuals with aortic stenosis may experience exercise intolerance, as their muscles may not receive an adequate oxygen supply during physical activity. This can manifest as fatigue, shortness of breath, and overall decreased exercise capacity. Pallor (choice A) is a pale appearance that may be seen in anemia or other conditions affecting blood flow but is not specific to aortic stenosis. Hyperactivity (choice B) and gastrointestinal disturbances (choice D) are not typically associated with aortic stenosis.

Correct Answer: D

Rationale: When preparing a sibling to see their brother in the pediatric intensive care unit after a near-drowning accident, it is essential to cover tubes and wires with a sheet, wash off any existing blood, and explain what the sibling will see. This approach helps the sibling understand the situation better and prepares them emotionally for the encounter, reducing potential distress and trauma. By providing information and visual preparation, the sibling can have a more controlled and less overwhelming experience when visiting their brother in the intensive care unit. Choice A is incorrect as informing the child that this could be the last time he sees his sibling may cause unnecessary distress and anxiety. Choice B is incorrect as it dismisses the sibling's emotional response, which is essential to address in a supportive manner. Choice C is incorrect as honesty and appropriate information sharing are crucial, even in difficult situations, to help the child cope effectively with the circumstances.

Correct Answer: A

Rationale: In this scenario, the priority is to assess the child's vital signs first, including heart rate, respiratory rate, and blood pressure. These data will provide critical information on the child's current physiological status and guide further interventions. Option B, recent exposure to communicable diseases, is not the priority in an acute ingestion situation. Option C, number of immunizations received, and option D, height and weight, are important but not as critical as assessing vital signs in this immediate situation.
