1. One of the major functions of the kidneys in maintaining normal fluid balance is:

Correct answer: C

Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.

2. A nurse is assessing an 18-year-old female who has recently suffered a TBI. The nurse notes a slower pulse and impaired respiration. The nurse should report these findings immediately to the physician due to the possibility the patient is experiencing which of the following conditions?

Correct answer: A

Rationale: The nurse should report the slower pulse and impaired respiration to the physician immediately as they are indicative of increased intracranial pressure (ICP) following a traumatic brain injury (TBI). These signs suggest that there may be a rise in pressure within the skull, which can be a life-threatening condition requiring urgent intervention. Options B and C are unlikely in this scenario as they do not correlate with the symptoms presented. Meningitis (Option D) typically presents with different signs and symptoms, such as fever, headache, and neck stiffness, which are not described in the patient's case.

3. A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?

Correct answer: B

Rationale: The correct answer is B: Alopecia. Chemotherapy drugs like vincristine can cause alopecia, which is hair loss. This side effect can significantly impact a patient's body image. While Cushingoid appearance (A) can be a side effect of long-term steroid use, temporary or permanent sterility (C) may affect a patient's future fertility but not necessarily alter body image. Pathologic fractures (D) are not common side effects of Hodgkin's disease or its treatment and do not directly contribute to a sense of altered body image in the same way as alopecia does.

4. The nurse is caring for a client with cirrhosis of the liver and suspects that the client may be developing hepatic encephalopathy. Which assessment by the nurse suggests that the client is developing this complication?

Correct answer: A

Rationale: Asterixis, also known as flapping tremors, is a characteristic sign of hepatic encephalopathy. It is a flapping tremor of the hands when the wrists are extended, indicating neurological impairment. Hypertension and Kussmaul respirations are not directly associated with hepatic encephalopathy. Lethargy is a common symptom but not a specific sign that suggests the development of hepatic encephalopathy.

5. A patient asks a nurse the following question: Exposure to TB can be best identified with which of the following procedures?

Correct answer: B

Rationale: The Mantoux test, also known as the tuberculin skin test, is the most appropriate and accurate test to identify exposure to TB. This test involves injecting a small amount of PPD tuberculin under the top layer of the skin, and a positive reaction indicates exposure to the TB bacteria. Choice A, a chest x-ray, is useful for detecting active TB disease but not exposure. Choice C, a breath sounds examination, is not a specific test for TB exposure. Choice D, a sputum culture for Mycobacterium tuberculosis, is used to diagnose active TB infection rather than exposure.
