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. What finding would the nurse expect to assess in a child with hypothyroidism?

A. Nervousness
B. Heat intolerance
C. Smooth velvety skin
D. Weight gain

Correct answer: D

Rationale: In a child with hypothyroidism, weight gain is a typical finding due to the slowed metabolism associated with the condition. This occurs because thyroid hormone levels are insufficient to regulate metabolism effectively. Choices A, B, and C are not typically associated with hypothyroidism. Nervousness is more commonly seen in conditions like hyperthyroidism, where there is an excess of thyroid hormones. Heat intolerance may be seen in hyperthyroidism as well, where the body's metabolism is increased. Smooth velvety skin is a characteristic finding in conditions like Cushing's syndrome, where there is excess cortisol production.

3. The parents of a newborn with phenylketonuria (PKU) need help and support in adhering to specific dietary restrictions. They ask the nurse, “How long will our child have to be on this diet?” How should the nurse respond?

A. “We are still not sure; you should discuss this with your health care provider.”
B. “If your baby does well, foods containing protein can gradually be introduced.”
C. “Your child needs to be on this diet at least through adolescence and into adulthood.”
D. “This is a lifelong problem, and it is recommended that dietary restrictions must be continued.”

Correct answer: D

Rationale: The correct answer is D: “This is a lifelong problem, and it is recommended that dietary restrictions must be continued.” PKU requires a lifelong adherence to a specific diet low in phenylalanine to prevent cognitive and developmental issues. Phenylalanine buildup can lead to irreversible damage, making it crucial for individuals with PKU to maintain dietary restrictions throughout their lives. Choices A, B, and C are incorrect because they do not address the lifelong nature of dietary restrictions necessary for PKU management.

4. What is the primary treatment for minimal change nephrotic syndrome?

A. corticosteroids
B. antihypertensive agents
C. long-term diuretics
D. increased fluids to promote diuresis

Correct answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome due to their immunosuppressive effects, which help reduce proteinuria and control the disease progression. Antihypertensive agents are not the primary treatment for this condition and are typically used to manage hypertension that may result from nephrotic syndrome. Long-term diuretics are not indicated in the treatment of minimal change nephrotic syndrome as they do not address the underlying cause. Increasing fluids to promote diuresis is not a recommended treatment for minimal change nephrotic syndrome, as it can exacerbate edema and fluid overload in these patients.

5. 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: The correct action in this scenario is to advise your partner to stop the ambulance and assist with the delivery. When the mother feels the urge to push and you see the baby's head bulging from the vagina, it indicates an imminent delivery. Stopping the ambulance allows for a safer environment for the delivery of the baby and ensures that immediate assistance can be provided to both the mother and the newborn. Allowing the head to deliver before checking for the cord (Choice A) may delay necessary interventions in case of complications. Instructing the mother to take short, quick breaths (Choice C) is not appropriate when the baby's head is already visible. Preparing for an emergency delivery and opening the obstetrics kit (Choice D) is important but should come after stopping the ambulance and assisting with the imminent birth.
