A child is brought to the emergency department experiencing an anaphylactic reaction to a bee sting. While an airway is being established, the nurse should prepare which medication for immediate administration?

Correct Answer: C

Rationale: In the management of anaphylaxis, the immediate medication of choice for administration is epinephrine. Epinephrine is a potent vasoconstrictor and bronchodilator which helps restore blood pressure and open up the airways during an anaphylactic reaction. It is the first-line treatment to reverse the potentially life-threatening effects of an allergic reaction. Other medications, like diphenhydramine or dobutamine, may be used as adjuncts later in the treatment, but epinephrine is crucial for immediate administration to stabilize the child's condition.

Correct Answer: D

Rationale: Sensitivity = (True positives / Truly infected) * 100 = (83 / 100) * 100 = 83%.

Correct Answer: C

Rationale: Nurse Galina should recognize an open anterior fontanel as a normal finding in a 2-year-old child. The anterior fontanel is a soft spot on a baby's skull where the skull bones have not yet fused together. It usually closes by the time a child is 18 to 24 months old. The open fontanel at 2 years of age is within the normal range of closure, and it is not a cause for concern in this case. No need to notify the doctor, look for other signs of abuse, or ask about a family history of Tay-Sachs disease based on this finding.

Correct Answer: A

Rationale: In preparing a 52-year-old male patient like Mr. Umali for a barium enema to evaluate acute ulcerative colitis, the nurse can expect that he will be contraindicated with cathartics. Cathartics, which are substances that induce bowel movements, are generally contraindicated in patients being evaluated for acute colitis as they can exacerbate the condition and cause additional discomfort. In contrast, using oil retention enemas or radiopaque tablets may not be suitable for a patient with acute ulcerative colitis. Positioning in a high Fowler's position following the procedure is not related to the preparation for a barium enema in this case.

Correct Answer: E

Rationale: Hepatitis C infection is not a recognized risk factor for hepatoblastoma.
