After years of struggling with weight management, a middle-age man is evaluated for gastroplasty.

He has experienced difficulty with managing his diabetes mellitus and hypertension, but he is approved for surgery.

Which intervention is most important for the nurse to include in this client's plan of care?

Choice A rationale:

Correcting electrolytes that are out of normal range is a crucial goal of therapy for this client. In diabetic ketoacidosis (DKA), the body’s cells are unable to use glucose for energy due to a lack of insulin. This leads to the breakdown of fat for energy, producing ketones as a by-product. Ketones are acidic and can cause the blood’s pH to decrease, leading to metabolic acidosis. This process also leads to an increased production and excretion of electrolytes such as potassium and sodium. Therefore, correcting these electrolyte imbalances is a key goal of therapy.

Choice B rationale:

While promoting oxygenation to tissues is generally important in critical care, it is not a specific goal in the management of DKA. The primary issues in DKA are metabolic in nature, including hyperglycemia, ketosis, and acidosis.

Choice C rationale:

Preventing hyperventilation is not a specific goal in the management of DKA. Hyperventilation in DKA is a compensatory mechanism for metabolic acidosis (Kussmaul breathing). The body tries to expel more carbon dioxide to reduce the acidity of the blood.

Choice D rationale:

Reversing dehydration is another important goal of therapy for this client. In DKA, high blood glucose levels lead to osmotic diuresis, where water is drawn into the urine from the blood, leading to dehydration. This can cause hypotension and reduced tissue perfusion. Therefore, reversing dehydration through fluid replacement is a key part of treatment.

Choice E rationale:

Replacing insulin is a fundamental goal of therapy for this client. Insulin deficiency is the primary cause of DKA. Insulin allows glucose to enter cells where it can be used for energy, preventing the breakdown of fat for energy and the subsequent production of ketones.

Choice F rationale:

Providing respiratory support may be necessary in severe cases of DKA where the patient’s compensatory respiratory efforts are insufficient to maintain adequate gas exchange. However, it is not one of the primary goals of therapy in DKA management.

Medication administration is a process that involves prescribing, dispensing, and giving medications to patients. It is a critical and complex task that requires accuracy, safety, and adherence to the rights of medication administration, such as the right patient, right drug, right dose, right route, right time, right documentation, and right response.

When a male client tells the practical nurse (PN) that the pill he has been taking at home is a different color and size than the one the PN is trying to give him now, this may indicate a potential medication error or discrepancy. A medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm. A medication discrepancy is any difference between the current and previous medication regimens of a patient.

The PN should respond to the client's concern by telling him that the PN will verify that the dispensed medication is the valid prescription. This means that the PN will check the medication label, the medication order, and the medication administration record (MAR) to confirm that the medication given to the client matches the one prescribed by the healthcare provider. The PN will also compare the dispensed medication with a drug reference guide or a picture of the medication to ensure that it is the correct drug and dosage form. The PN will also report any suspected errors or discrepancies to the healthcare provider or the pharmacy for clarification or correction.

Options A, B, and D are incorrect answers, as they do not reflect the appropriate or responsible actions for the PN to take when faced with a possible medication error or discrepancy.

Option A is incorrect because explaining that the healthcare provider probably prescribed a different medication while he is hospitalized is not true or helpful, as it does not verify or resolve the issue.

Option B is incorrect because telling the client that he is probably confused since being hospitalized tends to disorient clients is rude and dismissive, as it does not acknowledge or address the client's concern.

Option D is incorrect because explaining that the pharmacy often substitutes generic equivalents for more expensive brands is not accurate or relevant, as it does not verify or resolve the issue.
