An adult male was diagnosed with stage IV lung cancer three weeks ago.

His wife approaches the nurse and asks how she will know that her husband's death is imminent because their two adult children want to be there when he dies.

Which is the best response by the nurse?

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.

Choice A rationale:

Procure platelet products from the blood bank. Rationale: Procuring platelet products from the blood bank is a specialized task that requires specific training and authorization. It should be performed by licensed healthcare providers, such as nurses or physicians, rather than unlicensed assistive personnel (UAP).

Choice B rationale:

Titrate oxygen to the prescribed parameters. Rationale: Titrating oxygen to prescribed parameters requires clinical judgment and assessment skills, which are beyond the scope of practice for UAP. This task should be performed by licensed nurses or respiratory therapists.

Choice C rationale:

Monitor an intravenous infusion rate on an established schedule. Rationale: This is the correct answer. UAP can be trained to monitor intravenous (IV) infusion rates on an established schedule for clients who do not require complex adjustments. It is within their scope of practice to ensure that the IV is running at the prescribed rate and to report any abnormalities or concerns to the nursing staff.

Choice D rationale:

Insert a urinary catheter for an uncomplicated client. Rationale: Inserting a urinary catheter is a specialized nursing procedure that should only be performed by licensed nurses or healthcare providers. It is not within the scope of practice for UAP, even for uncomplicated cases.
