The nurse is aware that the following laboratory values support a diagnosis of pyelonephritis?
- A. Myoglobinuria
- B. Ketonuria
- C. Pyuria
- D. Low white blood cell (WBC) count
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.

A client has been receiving chemotherapy to treat cancer. Which assessment finding suggests that the client has developed stomatitis (inflammation of the mouth)?
- A. White, cottage cheese-like patches on the
- B. Red, open sores on the oral mucosa
- C. Rust-colored sputum
- D. Yellow tooth discoloration
Correct Answer: B
Rationale: Stomatitis is a common side effect of chemotherapy characterized by inflammation and irritation of the mucous membranes in the mouth. This can present as red, painful sores or ulcers on the oral mucosa. The presence of red, open sores in the mouth is indicative of stomatitis and warrants assessment and intervention to manage discomfort and prevent infection in the oral cavity. The other options are not typically associated with stomatitis in the context of chemotherapy.
In the presence of coma or unconsciousness, the major therapeutic measure includes:
- A. Maintenance of a clear airway
- B. Good nursing care
- C. Retention of catheter
- D. All of the above
Correct Answer: A
Rationale: In the presence of coma or unconsciousness, maintaining a clear airway is the major therapeutic measure to ensure adequate breathing and oxygenation. A clear airway is vital for the patient's survival and should be the priority to prevent respiratory distress or failure. Providing good nursing care is important for overall patient well-being, but ensuring a clear airway is crucial for immediate life support. Retention of a catheter is not a major therapeutic measure in the context of coma or unconsciousness unless specifically indicated for monitoring or treatment of underlying conditions. Therefore, the most critical intervention in this scenario is the maintenance of a clear airway.
The beta subunit of human chorionic gonadotropin (HCG) is a useful surface marker in some malignant germ cell tumors (GCTs); it is secreted by syncytiotrophoblasts. In which of the following GCTs this surface marker is characteristically elevated?
- A. teratoma
- B. germinoma
- C. endodermal sinus tumor
- D. embryonal carcinoma
Correct Answer: D
Rationale: Embryonal carcinoma is strongly associated with elevated beta-HCG levels.
