A nurse is caring for a client who has hyponatremia and is receiving an infusion of a prescribed hypertonic solution.
Which of the following findings should indicate to the nurse that the treatment is effective?
Improved cognition.
Cardiac arrhythmias absent.
Decreased vomiting.
Absent Chvostek’s sign.
The Correct Answer is A
Hyponatremia is a condition where the sodium level in the blood is too low, which can cause confusion, lethargy, seizures, and coma. A hypertonic solution is a fluid that has a higher concentration of solutes than the blood, which can help raise the sodium level and reduce the brain swelling caused by hyponatremia. Therefore, improved cognition indicates that the treatment is effective.
Choice B. Cardiac arrhythmias absent.
Cardiac arrhythmias are not a common symptom of hyponatremia unless it is severe or rapid in onset.
Therefore, their absence does not necessarily indicate that the treatment is effective.
Choice C. Decreased vomiting.
Vomiting can be a cause or a consequence of hyponatremia, depending on the underlying condition.
Decreased vomiting may indicate that the patient is less nauseated, but it does not reflect the sodium level or the brain status.
Choice D. Absent Chvostek’s sign.
Chvostek’s sign is a facial twitching that occurs when tapping on the cheek, which indicates hypocalcemia (low calcium level).
It is not related to hyponatremia or hypertonic solution.
Normal ranges for sodium are 135 to 145 mEq/L and for calcium are 8.5 to 10.5 mg/dL.

Correct Answer is B
Explanation
Albumin is a protein that helps maintain fluid balance in the body by drawing water into the blood vessels. Albumin infusion can increase the blood volume and blood pressure in patients who are in shock due to fluid loss or sepsis.
Choice A is wrong because albumin infusion does not decrease protein levels in the body.
Albumin is a protein itself and adding it to the blood increases the protein concentration.
Choice C is wrong because oxygen saturation of 96% is normal and does not indicate any improvement or deterioration in the patient’s condition.
Choice D is wrong because PaCO2 of 30 mm Hg is low and indicates respiratory alkalosis, which can be caused by hyperventilation, fever, or anxiety. Albumin infusion does not affect PaCO2 levels directly.
Correct Answer is ["A","B"]
Explanation
Fluticasone is an inhaled steroid that prevents the symptoms of asthma by decreasing inflammation in the airways. It is not used to treat a sudden asthma attack.
Some additional information to explain why the other choices are wrong are:
Choice C is wrong because soaking the inhaler in water after use can damage the device and affect its performance.
Choice D is wrong because fluticasone is not a rescue inhaler that can be used as needed for shortness of breath.It is a controller inhaler that should be used regularly as prescribed by the doctor.
Choice E is wrong because shaking the device prior to administration is not necessary for a fluticasone metered-dose inhaler (MDI).However, it is recommended for fluticasone inhalation powder (Flovent Diskus). Some normal ranges that may be applicable are:
The usual dose of fluticasone MDI for adults and children 12 years and older is 55 to 232 mcg twice a day.The usual dose of fluticasone MDI for children 4 to 11 years old is 30 mcg twice a day. The maximum dose of fluticasone MDI for adults and children 12 years and older is 1000 mcg twice a day.
