Nursing Elites

1. 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.

2. The nurse notes that a child has lost 8 pounds after 4 days of hospitalization for acute glomerulonephritis. This is most likely the result of

• A. poor appetite
• B. increased potassium intake
• C. reduction of edema
• D. restriction to bed rest

Correct answer: C

Rationale: The correct answer is C: reduction of edema. In acute glomerulonephritis, weight loss is often a result of the reduction of edema. Acute glomerulonephritis causes fluid retention and edema due to kidney inflammation. As the inflammation resolves with treatment, the kidneys can excrete excess fluid, leading to weight loss. Choices A, B, and D are incorrect. Poor appetite, increased potassium intake, and restriction to bed rest are not typically the primary reasons for weight loss in acute glomerulonephritis.

3. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

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

• A. Administer 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 immediately after clearing the airway to prevent hypothermia, which can lead to complications in newborns. Administering free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after ensuring the newborn's warmth. Obtaining an APGAR score is important but can be done after ensuring the newborn is kept warm and stable.

5. When assessing a child with suspected bacterial meningitis, what clinical manifestation is the nurse likely to observe?

• A. Photophobia
• B. High fever
• C. Rash
• D. Nasal congestion

Correct answer: B

Rationale: The correct answer is B: High fever. In bacterial meningitis, a high fever is a common clinical manifestation due to the body's inflammatory response to the infection. While photophobia (choice A) is also a common symptom in meningitis, it is not as specific as a high fever. Rash (choice C) is more commonly associated with viral infections or other conditions, rather than bacterial meningitis. Nasal congestion (choice D) is not a typical clinical manifestation of bacterial meningitis and is more commonly seen in respiratory infections. Therefore, when assessing a child with suspected bacterial meningitis, the nurse is most likely to observe a high fever as a key clinical manifestation.
