Nokea
An instructor is developing a plan for a class of nursing students on various skin disorders. When describing urticaria, what would the 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, not type IV. When triggered, histamine release leads to vasodilation, causing characteristic wheals. Wheals are typically followed by erythema. The rash in urticaria is pruritic and does blanch with pressure, unlike the nonpruritic rash described in choice D. Therefore, the most appropriate description of urticaria includes histamine release and vasodilation, as stated in choice B.

What behavior does a toddler subjected to prolonged hospitalization with limited parental visits typically exhibit?
- A. Cheerful interactions with staff members
- B. Indications of sadness throughout the day
- C. Excessive crying when parents are not present
- D. Limited emotional response to the environment
Correct Answer: D
Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits often exhibit a limited emotional response to the environment. This behavior is a common coping mechanism in young children facing such situations. While cheerful interactions with staff members (choice A) may occur occasionally, the overall response tends to be subdued. Indications of sadness throughout the day (choice B) and excessive crying when parents are not present (choice C) are less typical in this scenario, as the child may have learned to suppress emotions due to the challenging circumstances.
What is an early sign of congestive heart failure that the nurse should recognize?
- A. tachypnea
- B. bradycardia
- C. inability to sweat
- D. increased urinary output
Correct Answer: A
Rationale: Tachypnea is an early sign of congestive heart failure that nurses should recognize. Tachypnea refers to rapid breathing, which can be an indication of the body's attempt to compensate for decreased cardiac output in congestive heart failure. Bradycardia (choice B) is a slow heart rate and is not typically associated with congestive heart failure. Inability to sweat (choice C) and increased urinary output (choice D) are not specific early signs of congestive heart failure and are not typically recognized as such.
The healthcare provider is admitting a child with a Wilms tumor. Which is the initial assessment finding associated with this tumor?
- A. abdominal swelling
- B. weight gain
- C. hypotension
- D. increased urinary output
Correct Answer: A
Rationale: Abdominal swelling is a classic presentation and often the first noticeable sign of a Wilms tumor. This occurs due to the tumor mass in the kidney, leading to abdominal distension. Weight gain (Choice B) is less likely as a presenting symptom compared to abdominal swelling. Hypotension (Choice C) is not typically associated with a Wilms tumor unless complications like bleeding or shock occur. Increased urinary output (Choice D) is not a typical finding for Wilms tumor; instead, patients may present with hematuria or urinary symptoms.
The nurse is caring for a 12-year-old boy with idiopathic thrombocytopenia. The nurse is providing discharge instructions about home care and safety recommendations to the boy and his parents. Which response indicates a need for further teaching?
- A. We should avoid aspirin and medications like ibuprofen.
- B. He can resume participation in football in 2 weeks.
- C. Swimming would be a great activity.
- D. Our son cannot take any antihistamines.
Correct Answer: B
Rationale: Choice B indicates a need for further teaching because participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are correct. Avoiding aspirin and medications like ibuprofen helps prevent bleeding complications. Swimming is a safe physical activity that can be recommended. Antihistamines do not pose a significant risk in this case and can be used if needed.
At 0345, you receive a call for a woman in labor. Upon arriving at the scene, you are greeted by a very anxious man who tells you that his wife is having her baby 'now.' This man escorts you into the living room where a 25-year-old woman is lying on the couch in obvious pain. After determining that delivery is not imminent, you begin transport. While en route, the mother tells you that she feels the urge to push. You assess her and see the top of the baby's head bulging from the vagina. What is your most appropriate first action?
- A. Allow the head to deliver and check for the location of the cord.
- B. Advise your partner to stop the ambulance and assist with the delivery.
- C. Tell the mother to take short, quick breaths until you arrive at the hospital.
- D. Prepare the mother for an emergency delivery and open the obstetrics kit.
Correct Answer: B
Rationale: In this scenario, the most appropriate first action is to advise your partner to stop the ambulance and assist with the delivery. When the baby's head is visible and delivery is imminent, it is crucial to provide immediate assistance to ensure the safety of both the mother and the baby. Allowing the head to deliver and checking for the location of the cord (Choice A) may delay necessary actions during an imminent delivery. Instructing the mother to take short, quick breaths (Choice C) is not suitable as active delivery is already in progress. Preparing the mother for an emergency delivery and opening the obstetrics kit (Choice D) is not the most immediate action needed when the baby's head is already visible and delivery is imminent.
