Nursing Elites

1. The nurse is reviewing the laboratory test results of a child with Addison's disease. What would the nurse expect to find?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In Addison's disease, adrenal insufficiency leads to decreased aldosterone production. The decreased aldosterone results in impaired sodium reabsorption and potassium excretion, leading to hyperkalemia. Hypernatremia (Choice A) is unlikely because sodium reabsorption is impaired. Hyperglycemia (Choice C) is not a typical lab finding in Addison's disease. Hypercalcemia (Choice D) is not associated with Addison's disease; rather, it can be seen in conditions like hyperparathyroidism.

2. A nurse is teaching the parents of a toddler about the signs and symptoms of lead poisoning. Which symptom should the nurse emphasize?

• A. Abdominal pain
• B. Constipation
• C. Irritability
• D. Frequent urination

Correct answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers and should be emphasized to parents. Lead poisoning can manifest with various symptoms, but irritability is particularly common in children exposed to lead. Abdominal pain (Choice A) is not a typical symptom of lead poisoning in toddlers. While constipation (Choice B) can occur, it is less specific and less common than irritability. Frequent urination (Choice D) is not a typical symptom associated with lead poisoning in toddlers and is less relevant for parents to recognize in this context.

3. A nurse is teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about blood glucose monitoring. What should the nurse emphasize?

• A. Checking blood glucose levels before meals and at bedtime
• B. Using a lancet device to obtain blood samples
• C. Using urine test strips for monitoring
• D. Recognizing signs of hypoglycemia

Correct answer: A

Rationale: Checking blood glucose levels before meals and at bedtime is essential in managing type 1 diabetes mellitus as it helps in monitoring blood sugar levels at different times of the day and adjusting insulin doses accordingly. Option B about using a lancet device to obtain blood samples is a technique rather than an emphasis on monitoring frequency. Option C suggesting the use of urine test strips is incorrect as urine test strips are not recommended for accurate real-time monitoring of blood glucose levels in type 1 diabetes. Option D, recognizing signs of hypoglycemia, is important but not the primary emphasis when educating about blood glucose monitoring.

4. A group of students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?

• A. Regulation of water balance
• B. Hormonal secretion
• C. Cellular metabolism
• D. Growth stimulation

Correct answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

5. Why might a healthcare provider question a health care provider's order for a tap water enema for a 6-month-old infant with suspected Hirschsprung disease?

• A. The result could lead to loss of necessary nutrients.
• B. It could cause a fluid and electrolyte imbalance.
• C. It could increase the fear of intrusive procedures.
• D. The result could cause shock from a sudden drop in temperature.

Correct answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas are unlikely to lead to loss of necessary nutrients. Choice C is incorrect as it does not directly relate to the physiological risk of tap water enemas. Choice D is incorrect as shock from a sudden drop in temperature is not a common concern with tap water enemas.
