The nurse is aware that the following laboratory values support a diagnosis of pyelonephritis?

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: D

Rationale: Risk for obesity does not necessarily fall by 6 years.

Correct Answer: C

Rationale: The nurse should emphasize the leading cause of death topic related to firearm homicide to a group of African-American boys ranging in age from 15 to 19 years. This population is at a higher risk of being victims of firearm violence due to various socio-economic factors and systemic issues. By addressing the issue of firearm homicide, the nurse can provide important information on violence prevention, conflict resolution strategies, and community resources to help keep these young males safe. This education can potentially help reduce the risk of injury or death from firearm-related incidents within this vulnerable population.

Correct Answer: B

Rationale: Gay and lesbian adolescents are at a particularly high risk for suicide. Research has shown that sexual minority youth, such as gay, lesbian, bisexual, and transgender adolescents, are at a higher risk for suicide due to the stress, discrimination, and lack of acceptance they may face. It is important for the school nurse to address the unique risk factors and challenges faced by LGBTQ+ adolescents when discussing suicide prevention in order to provide appropriate support and resources.

Correct Answer: B

Rationale: The most likely serum sodium (Na) value for this patient would be within the normal range which is typically between 135-145 mEq/L. A value of 155mEq/L would be considered hypernatremia, which is an elevated level of sodium in the blood, and is not a likely serum sodium value in this case. A level of 110mEq/L would be extremely low and indicate hyponatremia, while a level of 165mEq/L would be dangerously high and could indicate severe hypernatremia. Therefore, option B, 155mEq/L, falls within the normal range and is the most likely serum sodium value for this patient.
