A patient with HIV-1 has experienced a sudden decline in health status accompanied by a significant increase in viral load. What is the first action the nurse should take?

Choice A rationale:
Incorrect. Deep-breathing exercises could potentially worsen stridor. Stridor is a high-pitched, wheezing sound caused by a partial obstruction of the upper airway. Deep breathing can increase airflow through the narrowed airway, making the stridor more pronounced and potentially worsening the obstruction. In severe cases, it could lead to complete airway obstruction and respiratory distress.
Risk of aggravation: Deep-breathing exercises could aggravate the underlying cause of stridor, such as laryngeal edema or vocal cord dysfunction, by increasing inflammation or muscle tension in the airway.
Delay in definitive treatment: Focusing on deep-breathing exercises might delay more definitive interventions, such as intubation, which might be necessary to secure the airway and prevent respiratory failure.
Choice B rationale:
Incorrect. While albuterol nebulizer therapy can be helpful for bronchospasm, it is not the first-line treatment for stridor. Stridor is typically caused by an upper airway obstruction, and albuterol primarily targets the lower airways (bronchioles).
Limited effectiveness: Albuterol might not be effective in reducing stridor caused by upper airway obstruction, as it does not directly address the narrowing of the airway.
Potential for adverse effects: Albuterol can cause tachycardia, tremors, and anxiety, which could further complicate the patient's condition.
Choice C rationale:
Not the most immediate action. While calling a Rapid Response might be necessary if the patient's condition deteriorates, the first priority is to secure the airway and ensure adequate ventilation.
Time-consuming: Activating a Rapid Response team can take several minutes, and the patient's condition might not allow for that delay.
Choice D rationale:
Prioritizes airway management: Intubation is the most effective way to secure the airway and ensure adequate ventilation in a patient with stridor. It bypasses the obstruction and allows for controlled delivery of oxygen and ventilation.
Addresses potential for deterioration: Stridor can rapidly progress to complete airway obstruction, so prompt preparation for intubation is crucial to prevent respiratory failure.
Involves the primary healthcare provider: Consulting the primary health care provider ensures timely decision-making, appropriate medication administration (such as sedatives or paralytics for intubation), and coordination of care.

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.
