Correct Answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available.

Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask.
Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask.
Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

Correct Answer: A

Rationale: Institute seizure precautions. The severity of the acute phase of AGN is variable and unpredictable; therefore, a child with edema, hypertension, and gross hematuria may be subject to complications, and anticipatory preparation such as seizure precautions is needed. Weighing the child twice per shift may be necessary for monitoring fluid balance but is not specifically related to the complications of AGN. Encouraging the child to eat protein-rich foods is important for overall nutrition but does not directly address the potential complications of AGN. Relieving boredom through physical activity is beneficial for overall well-being but is not the priority in this situation where seizure precautions are essential.

Correct Answer: C

Rationale: When a toddler is choking on a piece of food and appears blue, it indicates airway obstruction. The appropriate initial action should be to perform 5 abdominal thrusts. This technique can help dislodge the obstructing object and clear the airway. Initiating mouth-to-mouth resuscitation is not recommended as the first step in a choking emergency, especially in children. Giving water may not be effective and can worsen the situation by causing further blockage. Calling the emergency response team should be considered if the abdominal thrusts are unsuccessful in clearing the airway.

Correct Answer: B

Rationale: After an endoscopic procedure with general anesthesia, the priority nursing consideration is to not offer fluids, food, or any oral intake to the patient. Endoscopies involve passing a tube through the mouth into the esophagus or upper GI. Anesthesia is often given to inactivate the gag reflex, making the patient vulnerable to aspiration. Raising the siderails of the patient's bed is important for safety but not the immediate priority. Checking the patient's temperature may be important but is not the priority immediately after the procedure. Teaching the patient to avoid aspirin or NSAIDS is important for post-procedure care but is not the priority immediately after the endoscopic procedure.

Correct Answer: D

Rationale: Acute glomerulonephritis (AGN) is generally considered an immune-complex disease in response to a previous B-hemolytic streptococcal infection, typically occurring 4 to 6 weeks prior. It is not an infectious disease but a noninfectious renal condition.
Therefore, the parent's belief that the child 'caught' the disease is inaccurate.
Choice A is incorrect because AGN is not a direct streptococcal infection involving the kidney tubules but an immune response to a prior streptococcal infection.
Choice B is incorrect as AGN is not easily transmissible in schools and camps.
Choice C is incorrect as AGN is not usually associated with chronic respiratory infections but with a previous streptococcal infection.
