Nursing Diagnosis01:22

Nursing Diagnosis

3.9K
Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.
The nursing diagnosis focuses on evidence-based...

Electrical Current01:10

Electrical Current

7.1K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

Documentation of Nursing Diagnosis

1.7K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Formulating and Validating Nursing Diagnosis I

3.7K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.

Significance of Displacement Current01:27

Significance of Displacement Current

5.8K
A displacement current is analogous to a real current in Ampère's law, participating in Ampère's law the same way as the usual conduction current. However, it is produced by a changing electric field. Displacement current is defined in terms of a time-varying electric field, and also has an associated displacement current density. By adding a term accounting for displacement current, Maxwell modified the existing Ampère's law, which is now called generalized Ampère's law.

Summary
This summary is machine-generated.

Pleomorphic liposarcoma is a rare and aggressive soft tissue cancer. Diagnosis relies on identifying lipoblasts, which can be challenging due to their scarcity and similarity to other tumors.

Area of Science:

  • Oncology
  • Pathology
  • Soft Tissue Sarcomas

Background:

  • Pleomorphic liposarcoma is the rarest and most aggressive subtype of liposarcoma.
  • Typically affects deep soft tissues in adult extremities.
  • Lacks specific immunohistochemical or molecular markers, complicating diagnosis.

Purpose of the Study:

  • To provide an updated overview of pleomorphic liposarcoma's clinicopathologic features.
  • To discuss diagnostic challenges, including lipoblast identification and differential diagnosis.
  • To review morphologic variants and the utility of small biopsy samples.

Main Methods:

  • Review of existing literature on pleomorphic liposarcoma.
  • Analysis of clinicopathologic features, including morphology and diagnostic criteria.
  • Comparison with differential diagnoses, such as dedifferentiated liposarcoma.

Main Results:

  • Lipoblasts are the sole diagnostic criterion but are often scarce or focal.
  • Distinguishing pleomorphic liposarcoma from other pleomorphic sarcomas is difficult.
  • Small biopsy samples present additional diagnostic challenges.

Conclusions:

  • Accurate diagnosis of pleomorphic liposarcoma requires careful evaluation of lipoblasts.
  • Awareness of differential diagnoses and morphologic variants is crucial.
  • The role of small biopsy analysis in diagnosing this aggressive sarcoma is highlighted.
