– What risk factors for type 2 DM are present in this patient?

– What information (signs, symptoms, laboratory values) support the diagnosis

of type 2 DM?

-what is the therapeutic objective for treating this patient?

-what are the goals of this patient’s diabetes?

-considering his other medical problems, what other treatment goals should be

established?

     3& 4    Therapeutic Alternatives Optimal Plan

-what nonpharmacologic therapies might be useful in the management of this patient?

-what feasible pharmacotherapeutic alternatives are available for the treatment of

this patient’s DM?  -identify the factors that will influence your choice of initial therapy?

  -outline a complete pharmacotherapeutic plan to manage this patient’s current

problems including

  1. Drug name, dose & dosage, form, route, frequency, duration and purpose.
  2. Identify the medication classification
  3. Mechanism of action
  4. Major adverse effects and side effects
  5. Contraindications
  6. Safety alerts and precautions
  7. Determination of clinical efficacy

What clinical guideline/standard of practice guidelines support your medication selection? State the specific clinical guideline used.  How do these guidelines relate to your patient? Include dosage, patient variables, follow up, diagnostic tests, and maintenance regimens.

What changes in therapy would you recommend if your initial plan fails to

achieve adequate glycemic control?

Outcome Evaluation

5          -what clinical and laboratory parameters will you monitor to evaluate glycemic efficacy and to detect or prevent adverse effects?

– The patient’s physician suggested that he obtain a blood glucose meter for self testing.  What are the health care provider’s responsibilities with respect to patients and self monitoring of blood glucose (SMBG)?

 

-identify at least four potential situations in which the information provided by SMBG would be useful to patients and healthcare provoders.

-what factors should be considered in the selection of appropriate blood glucose

meter?

Patient Education

6. What information should be provided to this patient about diabetes and its treatment to enhance compliance, ensure successful therapy, minimize adverse and prevent future complications?

-how would you educate the patient regarding how and when to check his blood

glucose?

-what over the counter products could be recommended for patient to use in treating hypoglycemic episodes?

-list several potential sources of error in SMBG?

  1. Follow Up questions

-when starting a patient on insulin, the use of combination oral

antihyperglycemics agents and insulin affords several advantages over switching entirely to insulin.

  1. what are the advantages of adding insulin to existing therapies with oral agents?
  2. list an appropriate method of starting insulin therapy to adequately control

fasting hyperglycemia in patients on combination agents.
