Medical Surgical Huntington Disease #5

Question

A client is admitted with Huntington’s disease. The client’s parents asked the nurse how the diagnosis was made. What is the nurse’s best response?

Answers

  1. A positive family history of Huntington’s disease.
    • Rationale:

      This answer is correct because Huntington’s disease is a genetic inherited condition, therefore the disease is passed to the offspring by one parent. Diagnosis of Huntington’s disease includes a family history, clinical presentation of symptoms, and genetic testing of the person for chromosome 4.

  2. Clinical presentation of the client's symptoms.
    • Rationale:

      This answer is correct because Huntington’s disease can be diagnosed through clinical presentation of the client’s symptoms. Symptoms of Huntington’s disease may include: difficulty concentrating, lapses in memory, depression, hopelessness, stumbling, mood swings, irritability, aggressive behaviors, involuntary movements, loss of muscle control, fidgeting, and weight loss.

  3. Genetic testing the client for chromosome 4.
    • Rationale:

      This answer is correct because diagnosing Huntington’s disease is usually done through diagnostic testing such as genetic testing the client for chromosome 4. A single defective gene on chromosome 4 causes the disease. The defect is autosomal dominant meaning once the parent has developed Huntington’s disease, the offspring will eventually develop the disease.

  4. Having a cat scan of the head and body.
    • Rationale:

      This answer is not correct because a cat scan of the head and body do not reveal the problem with Huntington’s disease. Diagnosis of Huntington’s disease includes a family history, clinical presentation of symptoms, and genetic testing of the person for chromosome 4.

  5. Having an MRI of the brain.
    • Rationale:

      This answer is not correct because diagnosis of Huntington’s disease is not made by having an MRI of the brain. Diagnosis of Huntington’s disease includes a family history, clinical presentation of symptoms, and genetic testing of the person for chromosome 4.

Overview

Diagnosis of Huntington’s disease includes a family history, clinical presentation of symptoms, and genetic testing of the person for chromosome 4. Huntington’s disease is a genetic inherited condition where brain nerve cells over time break down causing cognition, psychiatric, and movement problems.

Explanation

Learning Outcomes

Huntington’s disease is a genetic inherited condition where brain nerve cells over time break down causing cognition, psychiatric, and movement problems. Symptoms of Huntington’s disease may include: difficulty concentrating, lapses in memory, depression, hopelessness, stumbling, mood swings, irritability, aggressive behaviors, involuntary movements, loss of muscle control, fidgeting, and weight loss. Diagnosing Huntington’s disease is usually done through diagnostic testing such as genetic testing the client for chromosome 4. A positive family history of Huntington’s disease would indicate that the client had the disease. Clinical presentation of the client’s symptoms is another way of diagnosing Huntington’s disease.

Test Taking Tip

Listen to the instructions given about taking the test. When you receive the test, read through the entire test once before answering any question. Relax and take a few deep breaths before beginning the test. Be sure you have properly studied to have the adequate recall needed for the test.
