One of the clinical manifestations of chronic renal failure is uremic frost. Which best describes this term?
- A. Deposits of urea crystals in urine
- B. Deposits of urea crystals on skin
- C. Overexcretion of blood urea nitrogen
- D. Inability of body to tolerate cold temperatures
Correct Answer: B
Rationale: Uremic frost is a term used to describe the presence of urea crystals on the skin of individuals with chronic renal failure. As kidney function declines in chronic renal failure, the body is unable to effectively excrete waste products such as urea. Urea can then be deposited on the skin when sweating, leading to the formation of white or frost-like crystals, giving the appearance of "uremic frost." This condition is a visible indicator of severe kidney dysfunction and the buildup of waste products in the body.

The nurse knows that Parkinson's disease a progressive neurologic disorder is characterized by:
- A. Bradykinesia
- B. Tremor
- C. Muscle rigidity
- D. All of the above
Correct Answer: D
Rationale: Parkinson's disease is a progressive neurologic disorder that is characterized by a triad of symptoms known as the classic Parkinsonian triad. These symptoms include bradykinesia (slowness of movement), tremor (involuntary shaking), and muscle rigidity (stiffness of the muscles). Therefore, all of the given choices are correct in describing the characteristics of Parkinson's disease.
A 14-year-old boy and his parents are concerned about bilateral breast enlargement. The nurse's discussion of this should be based on which statement?
- A. This is usually benign and temporary.
- B. This is usually caused by Klinefelter syndrome.
- C. Administration of estrogen effectively reduces gynecomastia.
- D. Administration of testosterone effectively reduces gynecomastia.
Correct Answer: A
Rationale: The correct statement is that bilateral breast enlargement in a 14-year-old boy is usually benign and temporary. This condition, known as gynecomastia, is commonly seen during puberty due to hormonal changes. It typically resolves on its own without the need for intervention. It is important for the nurse to reassure the boy and his parents that this is a normal occurrence and should not be a cause for major concern. It is crucial to address any underlying anxieties and provide education on the natural course of puberty-related changes.
A school nurse is conducting vision and hearing testing on fifth-grade children. Which level of prevention is the nurse demonstrating?
- A. Primary
- B. Secondary
- C. Tertiary
- D. Health promotion
Correct Answer: B
Rationale: The school nurse conducting vision and hearing testing on fifth-grade children is demonstrating the secondary level of prevention. Secondary prevention involves identifying and treating health conditions early to prevent their progression. In this scenario, the nurse's aim is to detect any existing vision or hearing problems in the children at an early stage so that appropriate interventions can be initiated to prevent further impairment or complications. This aligns with the goals of secondary prevention, which focuses on early detection, prompt intervention, and minimizing the impact of a health condition.
A 10-mo-old boy has a left suprarenal mass. Surgery is accomplished with complete removal of the mass as well as the non-adherent lymph nodes; surgical biopsies are taken during surgery. The histology reveals poorly differentiated neuroblastoma with microscopic ipsilateral lymph nodes involvement. The contralateral lymph nodes are negative. Of the following, the BEST therapeutic approach for this infant is
- A. chemotherapy
- B. radiotherapy
- C. concomitant chemo-radiotherapy
- D. chemotherapy followed by radiotherapy
Correct Answer: A
Rationale: Complete resection with microscopic residual disease typically warrants adjuvant chemotherapy.
