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.
During chemotherapy, an oncology client has a nursing diagnosis of impaired oral mucous membrane related to decreased nutrition and immunosuppression secondary to the cytotoxic effects of chemotherapy. Which nursing intervention is most likely to decrease the pain of stomatitis?
- A. Recommending that the client discontinue chemotherapy
- B. Providing a solution of hydrogen peroxide and water for use as a mouth rinse
- C. monitoring the client's platelet and leukocyte counts
- D. Checking regularly for signs and symptoms of stomatitis
Correct Answer: B
Rationale: Providing a solution of hydrogen peroxide and water for use as a mouth rinse is most likely to decrease the pain of stomatitis. Stomatitis is inflammation of the oral mucous membranes and can be quite painful for oncology clients undergoing chemotherapy. Using a solution of hydrogen peroxide and water as a mouth rinse can help reduce the risk of infection and promote healing of the mucous membranes, thereby decreasing the pain associated with stomatitis. This intervention helps to maintain oral hygiene and prevent further complications, making it an effective way to manage the client's symptoms while undergoing chemotherapy. It is important to note that discontinuing chemotherapy would not be a recommended intervention as it is the primary treatment for the client's cancer. Monitoring platelet and leukocyte counts and checking for signs and symptoms of stomatitis are important aspects of care, but providing a mouth rinse would directly address the pain and discomfort experienced by the client.
Which is true of a Wilms tumor? (Select all that apply.)
- A. It is also referred to as neuroblastoma.
- B. It is most commonly seen between the ages of 2 and 5 years.
- C. It can occur on its own or be associated with congenital anomalies.
- D. It is a slow-growing tumor.
Correct Answer: C
Rationale: Wilms tumor typically occurs in children aged 2-5 years and may be associated with congenital anomalies. It is not the same as neuroblastoma, and its prognosis is generally good with treatment.
A patient has hand-foot syndrome related to his sickle cell anemia. What findings does the nurse expect to see as the patient is assessed?
- A. Unequal growth of fingers and toes.
- B. Purplish discoloration of hands and feet.
- C. Webbing between fingers and toes.
- D. Deformities of the wrists and ankles.
Correct Answer: B
Rationale: Hand-foot syndrome, also known as dactylitis, is a common manifestation of sickle cell anemia. It is characterized by painful swelling and inflammation of the hands and feet, often resulting in a purplish discoloration due to decreased blood flow and oxygen delivery to the affected areas. This condition typically affects the soft tissues and joints of the hands and feet, leading to pain, swelling, and limited mobility. Unequal growth of fingers and toes, webbing between fingers and toes, and deformities of the wrists and ankles are not typically associated with hand-foot syndrome in sickle cell anemia.
