Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. A parent tells the nurse in the emergency department, 'My 3-year-old has had a fever for several days and has been vomiting.' After instituting ordered measures to reduce the fever, what nursing action is most important?

• A. Preventing shivering
• B. Restricting oral fluids
• C. Measuring output hourly
• D. Taking vital signs hourly

Correct answer: A

Rationale: Preventing shivering is crucial in this scenario as it can increase body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat through muscle activity, which can elevate the body temperature. Restricting oral fluids (choice B) is inappropriate as maintaining hydration is vital, especially in cases of fever and vomiting. Measuring output hourly (choice C) and taking vital signs hourly (choice D) are important nursing actions but not the most critical in this case where preventing shivering takes precedence.

3. A 4-year-old fell from a third-story window and landed on her head. She is semiconscious with slow, irregular breathing and bleeding from her mouth. After performing a jaw-thrust maneuver with simultaneous stabilization of her head, what should you do next?

• A. suction the oropharynx
• B. insert a nasopharyngeal airway
• C. initiate positive pressure ventilations
• D. place the patient in the recovery position

Correct answer: A

Rationale: In this scenario, the 4-year-old is presenting with signs of airway compromise due to the fall. After performing a jaw-thrust maneuver to open the airway while stabilizing the head to prevent further injury, the next step should be to suction the oropharynx. Suctioning helps to clear any blood or secretions from the mouth and throat, ensuring a clear airway for proper breathing. Inserting a nasopharyngeal airway or initiating positive pressure ventilations would be premature without first ensuring the airway is clear. Placing the patient in the recovery position is not indicated at this point as the focus should be on managing the airway.

4. A child with a diagnosis of appendicitis is scheduled for surgery. What preoperative intervention is important for the nurse to perform?

• A. Administering antibiotics
• B. Maintaining strict NPO status
• C. Encouraging fluid intake
• D. Monitoring for signs of infection

Correct answer: B

Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is maintaining strict NPO (nothing by mouth) status. This is crucial to reduce the risk of aspiration during anesthesia induction and prevent potential complications during surgery. Administering antibiotics may be a part of the treatment plan but is not a preoperative intervention. Encouraging fluid intake is contraindicated preoperatively to avoid delays in surgery and complications related to anesthesia. Monitoring for signs of infection is important postoperatively to assess for any complications that may arise due to the surgical procedure.

5. After clearing the airway of a newborn who is not in distress, what is the most important action for you to take?

• A. Apply free-flow oxygen
• B. Clamp and cut the cord
• C. Keep the newborn warm
• D. Obtain an APGAR score

Correct answer: C

Rationale: Keeping the newborn warm is crucial as newborns are at high risk of hypothermia due to their large body surface area and limited subcutaneous fat. Hypothermia can lead to complications such as respiratory distress, hypoglycemia, and metabolic acidosis. Providing warmth helps maintain the newborn's body temperature and supports physiological processes, promoting overall well-being. Applying free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after addressing the immediate need for warmth. Obtaining an APGAR score is important for assessing the newborn's overall condition but ensuring warmth takes precedence to prevent complications related to hypothermia.
