A male client tells the home health nurse that he has started taking magnesium hydroxide and aluminum hydroxide to treat occasional heartburn. It is most important for the nurse to review the client's medical history regarding the presence of which disorder?

A) Teach the client self-injection skills for daily subcutaneous administration: Insulin glargine is a long-acting insulin that is typically administered once daily via subcutaneous injection. Teaching the client how to properly administer insulin injections is crucial for managing type 2 diabetes effectively. Proper technique and routine are essential for ensuring correct dosing and preventing complications.

B) Demonstrate how to select dose based on before-meal blood sugar readings: Insulin glargine is not used for adjusting doses based on pre-meal blood sugar readings; it provides a steady baseline of insulin coverage throughout the day. Dose adjustments for type 2 diabetes are generally not based on meal-time glucose readings with long-acting insulin.
C) Explain to the family how to inject this medication for severe hypoglycemia: Insulin glargine is used to maintain long-term glucose control and is not typically used in emergency situations like severe hypoglycemia. Emergency treatment for severe hypoglycemia generally involves glucose administration rather than insulin injections.
D) Provide information on increasing medication dosage if ketoacidosis occurs: Insulin glargine is not adjusted based on acute conditions such as ketoacidosis. Management of diabetic ketoacidosis involves more immediate insulin and fluid management strategies, and dosage adjustments should be guided by a healthcare provider, not based on routine discharge instructions.

A) Pull up 30 units from the 70/30 vial, but only administer one third: The 70/30 insulin vial contains a mixture of 70% isophane (NPH) insulin and 30% regular insulin. If 30 units of this mixture are drawn, the actual amount of regular insulin would be 30% of 30 units, which equals 9 units. This does not equate to the 10 units of regular insulin required, making this option inaccurate for precise dosing.
B) Withdraw ten units regular insulin from the 70/30 vial: The 70/30 vial provides a fixed ratio of regular to NPH insulin. Extracting 10 units from this vial would not yield exactly 10 units of regular insulin; instead, it would include both types in the specified ratio, leading to an incorrect dosage of regular insulin.
C) Withhold the dose until insulin regular is available on the unit: Since the 70/30 vial contains a mixture and not solely regular insulin, it is necessary to withhold the dose until a vial of regular insulin is available. This ensures that the precise amount of regular insulin needed is administered, avoiding the imprecision and potential errors that could arise from using a mixed insulin vial.
D) Obtain a new vial of regular insulin and withdraw ten units: While obtaining a new vial of regular insulin is the correct approach for ensuring accurate dosing, the option of withdrawing ten units directly from a vial of regular insulin is not feasible if the current medication available is a mixture. This option assumes that the correct type of insulin is already available for use.
