A nurse is reviewing the laboratory results of a client who was hyperventilating during a panic attack.
Which of the following arterial blood gas values should the nurse expect?
pH 7.50 and HCO3 31 mm Hg.
pH 7.30 and HCO3 19 mm Hg.
pH 7.47 and PaCO2 31 mm Hg.
pH 7.32 and PaCO2 50 mm Hg.
The Correct Answer is C
The correct answer is: C.
Choice A reason: A pH of 7.50 and HCO3 of 31 mm Hg suggest a metabolic alkalosis due to the high bicarbonate level. However, during a panic attack, hyperventilation leads to respiratory alkalosis, not metabolic, due to the excessive exhalation of CO2, which is not consistent with this option.
Choice B reason: A pH of 7.30 and HCO3 of 19 mm Hg indicate a metabolic acidosis due to the low bicarbonate level. This is not typically associated with hyperventilation during a panic attack, which usually causes respiratory alkalosis, characterized by a decrease in CO2 levels and an increase in pH.
Choice C reason: A pH of 7.47 and PaCO2 of 31 mm Hg are indicative of respiratory alkalosis, which is expected during hyperventilation as a result of a panic attack. Hyperventilation causes a decrease in carbon dioxide (PaCO2) levels, leading to an increase in pH. The normal ranges for arterial blood gases are: pH 7.35-7.45, PaCO2 35-45 mm Hg, and HCO3 22-26 mEq/L.
Choice D reason: A pH of 7.32 and PaCO2 of 50 mm Hg suggest respiratory acidosis due to the elevated PaCO2 level. This would be more consistent with hypoventilation, which is not the case during a panic attack where hyperventilation occurs.

Correct Answer is A
Explanation
Choice A rationale:
Restricting visitation is an essential intervention during an influenza outbreak in a long-term care facility. Influenza is highly contagious and can spread rapidly among residents and staff in a close environment like a long-term care facility. By limiting visitation, the facility can reduce the risk of introducing the virus from the outside and help contain the outbreak. This is a preventive measure to protect vulnerable residents from exposure to the virus.
Choice B rationale:
Providing prophylactic antibiotics for clients who have been exposed to influenza is not a recommended intervention. Influenza is caused by a virus, not bacteria, so antibiotics are ineffective in preventing or treating the infection. Antibiotics should only be used to treat bacterial infections, not viral ones. Inappropriate use of antibiotics can lead to antibiotic resistance and other adverse effects.
Choice C rationale:
Implementing airborne precautions for clients who have influenza is not typically necessary. Influenza primarily spreads through respiratory droplets when an infected person coughs or sneezes. Standard precautions, such as proper hand hygiene and wearing masks when in close contact with infected individuals, are usually sufficient to prevent the spread of the virus. Airborne precautions are typically reserved for diseases that are transmitted through the airborne route, like tuberculosis.
Choice D rationale:
Assigning healthcare personnel to nondirect care activities for 24 hours after developing influenza symptoms is not a recommended intervention. While it's important for healthcare personnel to stay home when they are sick to prevent the spread of the virus, 24 hours may not be a necessary duration. The standard guideline for healthcare workers with influenza is to stay home until they are fever-free for at least 24 hours without the use of fever-reducing medications.
Correct Answer is C
Explanation
Choice A rationale:
Taking hydrochlorothiazide on an empty stomach is not a requirement for this medication. Hydrochlorothiazide is a diuretic used to treat conditions like hypertension and edema. It can be taken with or without food, and food may help reduce stomach upset for some individuals.
Choice B rationale:
Muscle weakness is an adverse effect of hydrochlorothiazide. Therefore, it is not an expected outcome. Hydrochlorothiazide is a thiazide diuretic, and one of its common side effects is potassium loss through increased urine output. This can lead to muscle weakness and cramping. The nurse should educate the client about the signs and symptoms of low potassium and the importance of including potassium-rich foods in their diet.
Choice C rationale:
Increasing daily intake of foods high in potassium is essential information to include in the teaching for a client taking hydrochlorothiazide. Thiazide diuretics like hydrochlorothiazide can cause potassium depletion, which may result in adverse effects like muscle weakness, cramping, and cardiac dysrhythmias. Therefore, advising the client to consume potassium-rich foods, such as bananas, oranges, and potatoes, can help counteract the potassium loss associated with the medication.
Choice D rationale:
Taking the medication at bedtime is not a specific requirement for hydrochlorothiazide. Thiazide diuretics can be taken at various times of the day, depending on the client's preferences and when they are most compliant with their medication regimen. The timing of administration should be consistent to maintain the medication's effectiveness.
