The practical nurse (PN) is assigned to care for a client with Guillain-Barré syndrome (GBS). Which problem has the highest priority for this client's care?

Choice A reason: Assessing urine for ketones is an important step in diagnosing diabetic ketoacidosis (DKA), a serious complication of diabetes. Ketones are produced when the body breaks down fat for energy due to a lack of insulin. High levels of ketones in the urine can indicate DKA. However, while this is a necessary assessment, it is not the immediate priority. The most urgent action is to measure the blood glucose to determine if hyperglycemia is present, which is a key indicator of DKA.
Choice B reason: Auscultating breath sounds is an important assessment to evaluate the client's respiratory status. Deep, rapid respirations (Kussmaul respirations) are often associated with DKA as the body attempts to compensate for metabolic acidosis. While auscultating breath sounds is valuable, it is not the first action to take. The primary concern is to confirm hyperglycemia, which is a critical step in diagnosing and managing DKA.
Choice C reason: Elevating the head of the bed can help improve the client's comfort and respiratory function, especially if they are experiencing difficulty breathing. However, this action does not directly address the underlying issue of hyperglycemia and potential DKA. While it can be part of supportive care, the immediate priority is to measure the blood glucose levels to assess the severity of the condition and initiate appropriate treatment.
Choice D reason: Measuring the blood glucose is the most critical and immediate action. Deep, rapid respirations and a fruity breath odor are classic signs of DKA, a life-threatening condition that requires prompt diagnosis and treatment. By measuring the blood glucose, the practical nurse can confirm hyperglycemia and initiate interventions to manage blood sugar levels, such as insulin administration and fluid replacement. Early detection and treatment are essential to prevent complications and stabilize the client’s condition.

Choice A reason: Sputum is the most appropriate specimen to collect prior to the initiation of antibiotic therapy in a client with suspected pneumonia. Sputum cultures can help identify the specific bacteria or other pathogens causing the infection, allowing for targeted antibiotic therapy. Collecting the sputum sample before starting antibiotics ensures that the culture results are not influenced by the medication, leading to more accurate identification of the causative agent and more effective treatment.
Choice B reason: Urine is not the appropriate specimen to collect for diagnosing pneumonia. While urine cultures can be useful for diagnosing urinary tract infections or detecting certain pathogens through urine antigen tests, they are not relevant to identifying the etiology of a respiratory infection like pneumonia. The focus should be on obtaining samples directly from the respiratory system.
Choice C reason: A throat smear can be useful for diagnosing upper respiratory tract infections, such as strep throat, caused by Group A Streptococcus. However, it is not the most relevant test for diagnosing pneumonia, which affects the lower respiratory tract. A sputum sample is more appropriate for identifying the pathogens responsible for pneumonia.
Choice D reason: Blood cultures can be useful for detecting bacteremia or septicemia, especially in severe cases of pneumonia where the infection has spread to the bloodstream. However, they are not the primary method for identifying the specific cause of pneumonia. Blood cultures are typically used in conjunction with other tests, such as sputum cultures, to provide a comprehensive diagnosis.
