The nurse caring for patients admitted for infectious diseases understands what information about emerging global diseases and bioterrorism?

Rationale for Choice A: Ensuring the client is warm
While maintaining client warmth is important for comfort and to prevent hypothermia, it is not the immediate priority upon arrival in the postoperative unit. Thermoregulation can be addressed after more urgent assessments have been completed.
Rationale for Choice B: Participating in hand-off report
A thorough hand-off report is essential for continuity of care, but it does not take precedence over assessing the client's immediate physiological status. The nurse can gather information from the report while simultaneously performing essential assessments.
Rationale for Choice C: Checking the surgical dressings
Monitoring surgical dressings is a crucial aspect of postoperative care, but it does not take priority over assessing fluid and blood output. Excessive bleeding or fluid shifts can rapidly compromise the client's hemodynamic stability and require prompt intervention.
Rationale for Choice D: Assessing fluid and blood output
This is the priority action for several reasons:
Monitoring for Hemorrhage: Early detection of excessive bleeding is crucial to prevent hypovolemic shock, a life-threatening complication. Postoperative bleeding can occur internally or externally, and prompt assessment of fluid and blood output allows for timely interventions to control bleeding and maintain hemodynamic stability.

Assessing Fluid Balance: Maintaining fluid balance is essential for optimal organ function and electrolyte balance. Postoperative clients are at risk for fluid imbalances due to blood loss, fluid shifts, and the use of diuretics or IV fluids. Assessing fluid intake and output helps to identify and address fluid imbalances early.
Evaluating Renal Function: Urine output is a key indicator of renal function. Postoperative clients are at risk for acute kidney injury due to factors such as hypotension, blood loss, and nephrotoxic medications. Assessing urine output helps to detect early signs of kidney dysfunction and initiate appropriate interventions.
Guiding Fluid and Blood Product Replacement: The assessment of fluid and blood output provides essential information to guide the administration of fluids and blood products as needed. This ensures that the client's fluid status and oxygen-carrying capacity are maintained within safe parameters.
Therefore, assessing fluid and blood output takes priority as it allows the nurse to identify and address potential life- threatening complications promptly, as well as guide interventions to maintain fluid balance and organ function.

Choice A rationale:
Metabolic alkalosis is a condition characterized by an increase in the pH of the blood due to an excess of bicarbonate (HCO3-) in the body. It is not typically caused by severe diarrhea. In fact, diarrhea can often lead to a loss of bicarbonate, which can contribute to metabolic acidosis.
Causes of metabolic alkalosis include: excessive vomiting, use of diuretics, and excessive intake of alkali such as antacids. Clinical manifestations of metabolic alkalosis include: muscle twitching, paresthesias, seizures, confusion, and lethargy.
Choice B rationale:
Respiratory alkalosis is a condition characterized by a decrease in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to an increase in blood pH. It is caused by hyperventilation, which removes excess CO2 from the body. Severe diarrhea does not typically cause hyperventilation.
Causes of respiratory alkalosis include: anxiety, hyperventilation syndrome, high altitude sickness, and pulmonary embolism. Clinical manifestations of respiratory alkalosis include: lightheadedness, dizziness, paresthesias, palpitations, and tetany.
Choice C rationale:
Respiratory acidosis is a condition characterized by an increase in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to a decrease in blood pH. It is caused by hypoventilation, which prevents the body from removing enough CO2. Severe diarrhea does not typically cause hypoventilation.
Causes of respiratory acidosis include: chronic obstructive pulmonary disease (COPD), pneumonia, asthma, and neuromuscular disorders.
Clinical manifestations of respiratory acidosis include: headache, confusion, somnolence, and coma.
Choice D rationale:
Metabolic acidosis is a condition characterized by a decrease in the pH of the blood due to an excess of acid in the body or a loss of bicarbonate. Severe diarrhea can lead to metabolic acidosis through several mechanisms:
Loss of bicarbonate in the stool: Diarrhea often contains a significant amount of bicarbonate, which can be lost from the body in large amounts during severe diarrheal episodes. This loss of bicarbonate can lead to a decrease in the blood's pH, resulting in metabolic acidosis.
Dehydration: Severe diarrhea can also lead to dehydration, which can concentrate acids in the blood and contribute to metabolic acidosis.
Lactic acidosis: In some cases, severe diarrhea can also cause lactic acidosis, a type of metabolic acidosis that occurs when there is a buildup of lactic acid in the body. This can happen due to impaired circulation or tissue hypoxia, which can occur as a complication of severe diarrhea.
