Correct Answer: D

Rationale: The correct initial action is to notify the healthcare provider of the child's status. The presenting symptoms described, such as irritability, thick muffled voice, croaking on inspiration, being hot to the touch, sitting leaning forward, tongue protruding, drooling, and suprasternal retractions, are indicative of epiglottitis, a potentially life-threatening condition. Immediate medical attention is crucial in such cases. While preparing for an X-ray or examining the throat may be necessary, the priority is to ensure prompt evaluation and intervention by the healthcare provider. Collecting a sputum specimen is not relevant in this situation and would cause unnecessary delay. Therefore, the nurse should prioritize communication with the healthcare provider to expedite appropriate management and treatment.

Correct Answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

Correct Answer: A

Rationale: The 1-4 day period after Xanax withdrawal is critical as it poses the highest risk of life-threatening seizures. Alprazolam is a benzodiazepine, and sudden cessation can lead to severe withdrawal symptoms. The patient's visible tremors, fear, pacing, and cognitive impairment indicate a state of heightened distress and potential seizure risk. Placing the patient on a stretcher with raised bed rails is essential for seizure precautions, ensuring safety and preventing injury during a potential seizure. Offering water and food, reassuring the patient, or informing the physician about Xanax withdrawal are not immediate priorities compared to managing the risk of seizures in this high-risk situation.

Correct Answer: C

Rationale: Vomiting undigested food that is not bile stained and constipation are classic symptoms of pyloric stenosis. Stools that are ribbon-like and a child who is eating poorly are signs of congenital megacolon (Hirschsprung's disease). An infant who suddenly becomes pale, cries out, and draws the legs up to the chest is demonstrating physical signs of intussusception. Crying during the evening hours, appearing to be in pain, eating well, and gaining weight are clinical manifestations of colic.

Correct Answer: D

Rationale: Various factors can lead to altered levels of consciousness in a patient. Alcohol consumption can depress the central nervous system and cause changes in consciousness. Electrolyte imbalances, such as hyponatremia or hypernatremia, can disrupt brain function and affect consciousness. Infections, especially those affecting the brain like encephalitis, can also lead to alterations in consciousness. Therefore, all of the choices provided - Alcohol, Electrolytes, and Infection - can potentially cause changes in the level of consciousness. Remember the acronym AEIOU-TIPPS to recall common causes of decreased level of consciousness, including Alcohol, Electrolytes, and Infection, among others.
