Which of the following is the function of macrophages and neutrophils?
- A. Phagocytosis
- B. Complement fixation
- C. Antibody production
- D. Suppression of autoimmunity
Correct Answer: A
Rationale: The function of macrophages and neutrophils is primarily phagocytosis, which is the process of engulfing and digesting pathogens such as bacteria, virus-infected cells, and cellular debris. Phagocytosis is a crucial defense mechanism of the immune system as it helps eliminate harmful invaders and promote tissue repair. Macrophages and neutrophils play key roles in innate immunity by recognizing, ingesting, and destroying pathogens to protect the body from infections.

The nurse is aware that a neonate of a mother with diabetes is at risk for what complication?
- A. Anemia
- B. Hypoglycemia
- C. Nitrogen loss
- D. Thrombosis
Correct Answer: B
Rationale: Neonates born to mothers with diabetes are at risk for hypoglycemia due to their exposure to high blood glucose levels in the womb. During pregnancy, the baby's pancreas produces extra insulin to handle the excess glucose from the mother, but after birth, there may be a sudden drop in blood glucose levels in the baby, leading to hypoglycemia. It is important to monitor blood glucose levels closely in these neonates and provide appropriate interventions to prevent and manage hypoglycemia. Anemia, nitrogen loss, and thrombosis are not typically associated with neonates of mothers with diabetes.
A parent of a child with acute renal failure (ARF) asks why peritoneal dialysis was chosen instead of hemodialysis. Which is the best response?
- A. Hemodialysis is not used in pediatrics.
- B. Peritoneal dialysis has no complications.
- C. Peritoneal dialysis removes fluid at a slower, more controlled rate, which minimizes complications.
- D. Peritoneal dialysis is more efficient than hemodialysis.
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Management of hypercalcemia includes all of the following actions except administration of:
- A. Fluid to dilute the calcium levels
- B. The diuretic furosemide (Lasix), without saline, to increase calcium excretion through kidneys
- C. Inorganic phosphate salts
- D. Intravenous phosphate therapy
Correct Answer: B
Rationale: While furosemide can increase calcium excretion through the kidneys, it may also exacerbate volume depletion and potentially lead to further increase in serum calcium levels. Therefore, administration of furosemide without proper saline or fluid replacement should be avoided in the management of hypercalcemia. The other options mentioned, such as giving fluids to dilute calcium levels, using inorganic phosphate salts, and providing intravenous phosphate therapy, are all appropriate measures in treating hypercalcemia.
