A nurse at an urgent care clinic is caring for a child who hit her head on the playground at school 30 minutes ago. Which of the following findings is the nurse's priority?

Choice A rationale:
Hypertension is a common manifestation of acute glomerulonephritis. The inflammation of the glomeruli in the kidneys can lead to impaired filtration, causing fluid retention and an increase in blood pressure. Monitoring the child's blood pressure is crucial to assess the severity of the condition and guide appropriate interventions.
Choice B rationale:
Dehydration is not a typical manifestation of acute glomerulonephritis. In fact, this condition often leads to fluid retention due to impaired kidney function. The child might experience edema and hypertension rather than dehydration.
Choice C rationale:
Muehrcke lines on the nails are not associated with acute glomerulonephritis. Muehrcke lines are white lines that appear horizontally across the nails and are typically indicative of hypoalbuminemia, which is not a primary feature of glomerulonephritis.
Choice D rationale:
Hypokalemia, or low potassium levels, is not a characteristic manifestation of acute glomerulonephritis. This condition primarily affects the kidneys' ability to filter waste and excess fluid, leading to fluid retention, electrolyte imbalances, and hypertension.

Choice A rationale:
A 15-year-old client who requests testing for a sexually transmitted infection (STI) is seeking healthcare related to sexual health, which is often considered confidential. In many jurisdictions, minors of a certain age (often 12 or older) have the legal right to consent to STI testing and treatment without parental consent. While education on sexual health and responsible decision-making is important, in this case, the nurse may not need to involve the parent if the legal requirements are met.
Choice B rationale:
This is the correct answer. Minors generally require parental consent for medical procedures, including biopsies. A biopsy involves a medical intervention that can carry risks, and it is important to have informed parental consent for procedures on underage clients.
Choice C rationale:
A 16-year-old client who requires prenatal care for pregnancy is not applicable in this scenario. Prenatal care is focused on managing the health and well-being of a pregnant individual and their developing fetus. The question does not provide information that suggests this situation.
Choice D rationale:
A 13-year-old client who requests contraception advice may have the right to access contraception services without parental consent, depending on local laws and regulations. Many places allow minors to access contraception services confidentially, recognizing the importance of sexual health and preventing unintended pregnancies. However, it's always important for healthcare providers to assess each situation and the applicable legal framework to determine whether parental involvement is required.
