A nurse is discussing with a colleague who is relocating to a new state and needs to find a new job there. What is the best advice the nurse can give?

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.

Choice A: Clarify that these precautions are mandated by law.
While it's important to acknowledge the legal requirements for Contact Precautions, this approach alone may not adequately address the family's emotional concerns and fears. It could potentially increase their anxiety if they feel forced to visit without understanding the reasons behind the precautions.
Choice B: Emphasize the importance of their visit to the patient.
While family support is crucial for the patient's well-being, emphasizing the importance of their visit without addressing their fears could inadvertently pressure them to visit without feeling comfortable or confident in their ability to protect themselves.
Choice C: Assure the family that they will not contract the infection.
It's not always possible to guarantee that the family won't contract the infection. Making such assurances could create a false sense of security and potentially lead to lapses in infection control practices.
Choice D: Demonstrate to the family how to prevent the spread of the disease.
Empowering the family through education and demonstration is the most effective approach. It addresses their concerns directly, promotes understanding, and instills confidence in their ability to protect themselves while visiting.
Key elements of this demonstration include:
Proper hand hygiene techniques
Use of personal protective equipment (PPE) such as gloves and gowns Safe handling of potentially contaminated items
Maintaining a safe distance from the patient when appropriate Understanding the modes of transmission for the specific disease
By providing clear guidance and allowing for practice, the nurse can help the family feel more comfortable and confident in their ability to visit safely.
Additional considerations:
Addressing the family's emotional concerns: Acknowledge their fears and provide reassurance in a compassionate and understanding manner.
Tailoring education to the family's level of understanding: Use simple language and visual aids as needed.
Encouraging questions and open communication: Create a supportive environment where the family feels comfortable asking questions and expressing their concerns.
Collaborating with other healthcare professionals: Involve infection control specialists or other relevant team members to provide additional support and expertise.
