A nurse is caring for a client who requires isolation for active pulmonary tuberculosis. Which of the following precautions should the nurse include when creating a sign to post outside of the client's room? (Select all that apply.)

A. Contacting the pharmacy might be a good step in some cases, but if the nurse has identified a dosage that is three times higher than usual, it's crucial to address this directly with the prescribing provider first.
B. Asking another nurse to verify is a reasonable step, but ultimately, it's the responsibility of the nurse who identifies the discrepancy to take action.
C. Informing the charge nurse and administering the dose without questioning the provider's order could potentially put the client at risk if the dosage is indeed too high.
D. Contacting the provider to question the dosage is the most appropriate immediate action. It's crucial to seek clarification from the provider regarding the unusually high dosage to ensure the safety and well-being of the client. This step ensures that the client receives the correct and safe medication dosage.

a. Hypertension and crackles:

While hypertension can be associated with various conditions, such as cardiovascular diseases or stress, it is not directly related to the cessation of TPN infusion.

Crackles in the lungs are often indicative of fluid accumulation or inflammation, commonly seen in conditions like pneumonia or heart failure. They are not typically associated with the interruption of TPN infusion.

b. Fever and chills:

Fever and chills can be symptoms of infection or inflammatory processes in the body. However, they are not specifically related to the interruption of TPN infusion.

In the context of TPN cessation, the focus would be on metabolic changes rather than infectious processes.

c. Excessive thirst and urination:

Excessive thirst and urination are classic symptoms of hyperglycemia, which can occur when TPN, particularly if it contains a high glucose concentration, is abruptly interrupted.

When TPN infusion stops, there is no longer a continuous supply of glucose to the body, leading to increased blood glucose levels and subsequent polyuria (excessive urination) and polydipsia (excessive thirst) as the body tries to eliminate excess glucose.

d. Shakiness and diaphoresis:

Shakiness and diaphoresis (excessive sweating) are classic symptoms of hypoglycemia, which can occur if TPN, particularly if it contains a high concentration of insulin, is abruptly interrupted.

TPN solutions often contain glucose and insulin to maintain proper blood glucose levels. If the infusion is stopped suddenly, there may be a rapid decline in blood glucose levels, leading to hypoglycemia, which manifests as shakiness, diaphoresis, confusion, and other neuroglycopenic symptoms.
