Correct Answer: B

Rationale: The correct answer is to emphasize emptying the child's mouth in any case of possible poisoning. This action is crucial to prevent further ingestion of the poisonous substance. Choice A is incorrect because calling the Poison Control Center should be one of the first steps, not waiting until the situation is identified. Choice C is incorrect as moving the child may spread or exacerbate the effects of the toxic substance. Choice D is incorrect because inducing vomiting can be harmful if the poison is a hydrocarbon, as it may lead to aspiration.

Correct Answer: A

Rationale: The correct answer is A: Cotton balls. Cotton balls are not suitable for tracheostomy care due to the risk of lint and contamination. When performing tracheostomy care, sterile supplies such as sterile gloves, a suction catheter, and tracheostomy tubes are essential. Sterile gloves are needed to maintain asepsis, a suction catheter is necessary for airway clearance, and tracheostomy tubes are crucial for maintaining a patent airway. Cotton balls should be avoided to prevent introducing lint or fibers into the tracheostomy site, which can lead to infection or airway obstruction.

Correct Answer: C

Rationale: Cough with bloody sputum is a hallmark symptom of tuberculosis and is highly concerning as it indicates active disease. Hemoptysis (coughing up blood) is associated with tuberculosis infection in the lungs. While night sweats and weight loss are common symptoms of tuberculosis, they are less specific than coughing with bloody sputum. Fatigue is a nonspecific symptom that can be present in various conditions and is not specific to tuberculosis.

Correct Answer: B

Rationale: The correct answer is B: Moist sterile non-adherent dressing. A moist sterile non-adherent dressing is suitable for covering a neural tube defect and would not require further intervention. This type of dressing helps prevent the dressing from sticking to the wound, minimizing trauma during dressing changes. Choice A, Telfa dressing with antibiotic ointment, is not ideal for a neural tube defect as the ointment may not be necessary and can complicate wound care. Choice C, dry sterile dressing that is occlusive, is not recommended for a neural tube defect as it may not provide the necessary environment for proper wound healing. Choice D, sterile occlusive pressure dressing, is excessive for a neural tube defect and may cause unnecessary pressure on the wound site.

Correct Answer: A

Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.
