The nurse provides care for a client with deep partial-thickness burns. What could cause a reduced hematocrit (Hct) in this client?

Correct Answer: B

Rationale: A reduced hematocrit (Hct) in a client with deep partial-thickness burns can be primarily caused by volume overload with hemodilution. In patients with burns, there is an initial shift of fluid from the intravascular space to the interstitial space, leading to a decreased intravascular volume. In response to this hypovolemia, there is an increased release of antidiuretic hormone (ADH) and aldosterone, resulting in retention of water and sodium. This volume overload leads to hemodilution, where the proportion of red blood cells to plasma decreases, causing a reduction in hematocrit levels. This scenario is a common occurrence in clients with burn injuries and helps explain the reduced hematocrit in this client.

Correct Answer: C

Rationale: The nursing diagnosis that takes the highest priority for a client in a late stage of AIDS with signs of AIDS-related dementia is Ineffective cerebral tissue perfusion. This diagnosis is prioritized because AIDS-related dementia is associated with changes in brain function due to HIV affecting the brain tissues. Ensuring adequate cerebral perfusion is crucial to maintaining brain function and preventing further deterioration. Monitoring and addressing any factors that could affect cerebral perfusion, such as blood pressure, oxygenation, and circulation, are essential in managing this condition. Other nursing diagnoses are also important, but addressing ineffective cerebral tissue perfusion should be the highest priority in this situation to prevent further complications related to neurological function.

Correct Answer: B

Rationale: Pulmonary complications are the most common problem in caring for AIDS patients due to Pneumocystis pneumonia, also known as Pneumocystis jirovecii pneumonia or PCP. PCP is an opportunistic infection caused by the fungus Pneumocystis jirovecii, previously known as Pneumocystis carinii. This particular type of pneumonia is a prevalent and potentially life-threatening infection in individuals with weakened immune systems, such as those with AIDS. PCP is a major cause of morbidity and mortality in AIDS patients due to the compromised immune system's inability to effectively fight off the infection. Prompt diagnosis and treatment of PCP are crucial in the care of AIDS patients to improve outcomes and reduce the risk of respiratory complications.

Correct Answer: A

Rationale: During the Schilling test, which is used to evaluate the absorption of vitamin B12 in the gastrointestinal system, the essential nursing intervention is to collect urine samples 24-48 hours after the client has received nonradioactive B12. The test involves administering both radioactive and nonradioactive forms of vitamin B12 to the client. The client's ability to absorb the vitamin B12 is assessed by measuring the amount of labeled B12 in the urine over the specified time period. This helps in diagnosing conditions such as pernicious anemia or malabsorption of vitamin B12. Blood samples are not typically collected for this test, and allowing fluid consumption is important to keep the client hydrated. The client does not need to lie down in a specific position for an extended period following nonradioactive B12 administration.
