Nursing Elites

1. An infant who has had diarrhea for 3 days is admitted in a lethargic state and is breathing rapidly. The parent states that the baby has been ingesting formula, although not as much as usual, and cannot understand the sudden change. What explanation should the nurse give the parent?

• A. Cellular metabolism is unstable in young children.
• B. The proportion of water in the body is less than in adults.
• C. Renal function is immature in children until they reach school age.
• D. The extracellular fluid requirement per unit of body weight is greater than in adults.

Correct answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.

2. The nurse is assessing a 9-year-old girl with a history of tuberculosis at age 6 years. She has been losing weight and has no appetite. The nurse suspects Addison disease based on which assessment findings?

• A. Arrested height and increased weight
• B. Thin, fragile skin and multiple bruises
• C. Hyperpigmentation and hypotension
• D. Blurred vision and enuresis

Correct answer: C

Rationale: In a child with suspected Addison disease, the presence of hyperpigmentation (bronzing of the skin) and hypotension are key clinical findings. Hyperpigmentation is due to increased ACTH stimulation, resulting in melanocyte stimulation. Hypotension occurs due to decreased aldosterone production and subsequent sodium loss. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease; thin, fragile skin and multiple bruises are more indicative of conditions like Cushing's syndrome; blurred vision and enuresis are not typically associated with Addison disease.

3. 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.

4. During a physical examination of an infant with Down syndrome, what anomaly should the healthcare provider assess the child for?

• A. Bulging fontanels
• B. Stiff lower extremities
• C. Abnormal heart sounds
• D. Unusual pupillary reactions

Correct answer: C

Rationale: Infants with Down syndrome are at increased risk of congenital heart defects. Therefore, assessing for abnormal heart sounds is crucial during the physical examination. Bulging fontanels are not typically associated with Down syndrome and may indicate increased intracranial pressure. Stiff lower extremities are not a common finding in Down syndrome and may suggest other musculoskeletal issues. Unusual pupillary reactions are not typically linked to Down syndrome and may be indicative of neurological problems instead.

5. What explanation should be given to a parent about the purpose of a tetanus toxoid injection for their child?

• A. Passive immunity is conferred for life.
• B. Long-lasting active immunity is conferred.
• C. Lifelong active natural immunity is conferred.
• D. Passive natural immunity is conferred temporarily.

Correct answer: B

Rationale: The correct answer is B: 'Long-lasting active immunity is conferred.' Tetanus toxoid injection provides long-lasting active immunity by stimulating the body to produce its own antibodies. Choice A is incorrect because tetanus toxoid injection does not provide passive immunity. Choice C is incorrect because the immunity conferred by the vaccine is not natural but artificially induced. Choice D is incorrect as the immunity provided by the tetanus toxoid injection is active, not passive.
