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
This will help reduce swelling and discomfort caused by the infiltration of fluid into the tissues. Elevating the extremity also promotes venous return and prevents further fluid accumulation.
Choice A is wrong because applying pressure to the IV site can increase the risk of tissue damage and infection.
Pressure can also obstruct blood flow and cause thrombophlebitis.
Choice C is wrong because slowing the infusion rate will not stop the infiltration of fluid into the tissues.
Slowing the infusion rate can also delay the delivery of medication or fluid to the client.
Choice D is wrong because flushing the IV catheter can worsen the infiltration of fluid into the tissues.
Flushing the IV catheter can also introduce air or bacteria into the bloodstream and cause complications.
Normal ranges for peripheral IV infusion are dependent on the type and volume of fluid, the size and location of the catheter, and the condition of the client. Generally, peripheral IV infusion rates should not exceed 100 mL/hr for adults and 60 mL/hr for children.
Correct Answer is C
Explanation
Urticaria, also known as hives, is a common sign of an allergic reaction to penicillin. An allergic reaction is an abnormal response of the immune system to the drug. Other signs and symptoms of penicillin allergy may include skin rash, itching, fever, swelling, shortness of breath, wheezing, runny nose, itchy eyes, and anaphylaxis. Anaphylaxis is a rare but life-threatening condition that affects multiple body systems and requires immediate emergency treatment.
Choice A is wrong because pallor is not a typical sign of an allergic reaction to penicillin.
Pallor means pale skin and may be caused by other conditions such as anemia or shock.
Choice B is wrong because bradycardia is not a typical sign of an allergic reaction to penicillin.
Bradycardia means slow heart rate and may be caused by other conditions such as heart block or medication side effects.
Choice D is wrong because dyspepsia is not a typical sign of an allergic reaction to penicillin.
Dyspepsia means indigestion and may be caused by other conditions such as gastritis or peptic ulcer.
