Suggestions of use

Authors do not recommend using poor knowledge as a tag for a problem for the following reasons:

  • Deficient knowledge is not a true human response.
    • “Answer” suggests behavior or action, while deficient knowledge is simply a state.
  • Deficient knowledge does not necessarily describe a state of health.
  • Deficient knowledge does not necessarily describe a problem.
    • Nursing diagnoses should reflect an alteration of functioning, but poor knowledge only indicates that the person lacks certain knowledge, not that their operation has changed as a result of such lack of knowledge.
    • Poor knowledge can contribute to several responses to problems such as anxiety, alteration in relating or familiarizing, self -care or ineffective coping deficit. Therefore, it can be used effectively as the etiology of a nursing diagnosis (for example, risk of injury or trauma, regarding the lack of knowledge of the correct use of the safety belt during pregnancy or anxiety related to the lack of knowledge on procedures related to bone marrow aspiration).
    • If poor knowledge is used as part of the problem of a nursing diagnosis, an objective should be: “The patient acquires knowledge about …”. This makes the nursing professional dedicate to information instead of focusing on the behaviors derived from the lack of knowledge of the patient, reinforcing the belief that the supply of information will change the behavior and solve the problems.
    • On the other hand, when poor knowledge is used as etiology, it directs attention to behaviors that indicate insecurity, conflict when making decisions, anxiety, etc. It is convenient to keep the difference in nursing care suggested by the following diagnoses:
    • Poor knowledge (bone marrow aspiration) related to the lack of previous experience
    • Anxiety related to poor knowledge (marrow aspiration
    • bone)
    • Educating the patient is an important intervention for most patients and in all nursing diagnoses (for example, constipation, ineffective breastfeeding). Therefore it is not necessary, or desirable, that there is a diagnosis of poor knowledge in the care plan of each patient. Nursing professionals must include education as one of the nursing interventions for all other diagnoses they do.
    • Some patients, such as a newly diagnosed diabetic, require many teachings to acquire the necessary self -care skills.
    • These special teaching plans should be part of the routine of standard care plans for these patients, and should not require an individual nursing diagnosis. However, if the institution does not have a standardized plan or protocol, it will be necessary to write an individualized teaching plan. Even in that case, poor knowledge should be used as the etiology of an answer, for example, risk of ineffective health management (diabetes management) related to poor knowledge (medicines, diet, exercise and dermatological care) secondary to the new diagnosis .
    • In case of being used, poor knowledge should describe conditions in which the patient needs new or additional knowledge. It should not be used for problems related to patient learning inability (for example, poor knowledge related to great anxiety about the result of surgery). Rakel and Bulechek (1990) propose a diagnosis of situational learning disability: learning inability or disability of situational learning: lack of motivation to learn for problems like these. However, these labels are not included in Nanda-I.
    • At least two studies have shown that deficient knowledge is one of the most used (erroneous) diagnoses in nursing (Gordon, 1985; Lambert and Jones, 1989). It is possible that this is due, in part, to a premature diagnosis: it is easy to recognize poor knowledge, qualify it as a problem and not see beyond the human response to that lack of knowledge. The misuse of this diagnosis is also due to the wrong belief that information will change human behavior.
