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. The parents of a 6-week-old infant who was born without an immune system ask a nurse why their baby is still so healthy. How should the nurse reply?

• A. Exposure to pathogens during this time can be limited.
• B. Some antibodies are produced by the infant’s colonic bacteria.
• C. Antibodies are passively received from the mother through the placenta and breast milk.
• D. Fewer antibodies are produced by the fetal thymus during the eighth and ninth months of gestation.

Correct answer: C

Rationale: The correct answer is C. Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially. Choice A is incorrect because a 6-week-old infant born without an immune system would not be able to limit exposure to pathogens effectively. Choice B is incorrect as antibodies produced by colonic bacteria are not a significant source of immunity in infants. Choice D is incorrect as the fetal thymus primarily plays a role in T cell development rather than antibody production during gestation.

3. A 2-year-old child who was admitted to the hospital for further surgical repair of a clubfoot is standing in the crib, crying. The child refuses to be comforted and calls for the mother. As the nurse approaches the crib to provide morning care, the child screams louder. Knowing that this behavior is typical of the stage of protest, what is the most appropriate nursing intervention?

• A. Use comforting measures while holding the child.
• B. Fill the basin with water and bathe the child.
• C. Sit by the crib and bathe the child later when the anxiety decreases.
• D. Postpone the bath for a day because a child this upset should not be traumatized further.

Correct answer: C

Rationale: During the stage of protest, children may display distress when separated from their primary caregiver. Sitting by the crib and providing comfort when the child is less anxious is an appropriate intervention. Choice A is incorrect because attempting to hold the child while they are in distress may escalate the situation. Choice B is inappropriate as it ignores the child's emotional distress and proceeds with a task that can wait. Choice D is not the best option as postponing the bath for a day is not necessary; instead, addressing the child's emotional needs promptly is crucial in this situation.

4. A child has coarctation of the aorta. What does the nurse expect to identify when taking the child’s vital signs?

• A. A weak radial pulse
• B. An irregular heartbeat
• C. A bounding femoral pulse
• D. An elevated radial blood pressure

Correct answer: A

Rationale: When a child has coarctation of the aorta, the nurse would expect to identify a weak radial pulse when taking the child's vital signs. Coarctation of the aorta results in a narrowing of the aorta, leading to reduced blood flow and a weakened pulse. An irregular heartbeat (Choice B) is less likely to be associated with coarctation of the aorta. Similarly, a bounding femoral pulse (Choice C) is not typically observed with this condition. An elevated radial blood pressure (Choice D) is less common as coarctation of the aorta usually causes decreased blood pressure in the lower extremities due to the aortic narrowing.

5. 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, which refers to rapid breathing, is an early sign of congestive heart failure. In heart failure, the heart's inability to pump efficiently can lead to fluid accumulation in the lungs, causing the child to breathe faster to try to compensate for the decreased oxygen exchange. Bradycardia (slow heart rate) is not typically associated with congestive heart failure; instead, it may indicate a different issue. Inability to sweat is not a common early sign of congestive heart failure. Increased urinary output is not a typical early sign of congestive heart failure; instead, it may be a sign of other conditions like diabetes or kidney issues.
