A 12-month-old boy weighed 8 lb 2 oz at birth. What weight should the nurse expect him to be now?

Correct Answer: C

Rationale: Infants typically triple their birth weight by 12 months. For an 8-lb infant, that would be approximately 24 lb.

Correct Answer: B

Rationale: Recognizable external genitalia are formed by 14 weeks, not 12 weeks.

Correct Answer: C

Rationale: Pyelonephritis is a bacterial infection of the kidney. One of the key indicators of pyelonephritis is the presence of pyuria, which refers to white blood cells in the urine. White blood cells in the urine suggest inflammation and infection in the urinary tract, particularly in the kidneys. Therefore, the presence of pyuria supports a diagnosis of pyelonephritis. Myoglobinuria (choice A) is the presence of myoglobin in the urine and is associated with muscle breakdown, not specifically with pyelonephritis. Ketonuria (choice B) refers to the presence of ketones in the urine and may be seen in conditions such as diabetic ketoacidosis. A low white blood cell count (choice D) is not typically associated with pyelonephritis, as an infection would generally result in an elevated white blood cell count in response to the infection.

Correct Answer: B

Rationale: Clear liquids are gentle on the liver and help minimize digestive stress during hepatitis.

Correct Answer: C

Rationale: Etoposide is known to be associated with secondary AML due to its potential to induce chromosomal abnormalities.
