A nurse is preparing to initiate IV therapy for a client.
Which of the following sites should the nurse use to place the peripheral IV catheter?
Dominant antecubital basilic vein.
Nondominant dorsal venous arch.
Dominant distal dorsal vein.
Nondominant forearm basilic vein
The Correct Answer is D
This site is preferred for peripheral IV catheter placement because it is comfortable, has good blood flow, and has a lower risk of complications than the dominant arm or the antecubital fossa.
Choice A is wrong because the dominant antecubital basilic vein is more prone to dislodgement, thrombosis, and thrombophlebitis due to frequent movement of the elbow joint.
Choice B is wrong because the nondominant dorsal venous arch is a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.
Choice C is wrong because the dominant distal dorsal vein is also a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.

Correct Answer is B
Explanation
According to the CDC, people with severe, life-threatening allergies to any ingredient in a flu vaccine (other than egg proteins) should not get that vaccine. However, people with egg allergy can get a flu vaccine. The CDC also states that people who have had a severe allergic reaction to a dose of influenza vaccine should not get that flu vaccine again and might not be able to receive other influenza vaccines. Therefore, a nurse should report an egg allergy to the provider as a possible contraindication to receiving the vaccine.
Choice A is wrong because shellfish is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice C is wrong because milk is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice D is wrong because peanuts are not an ingredient in a flu vaccine and are not a contraindication to receiving the vaccine.
Correct Answer is A
Explanation
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.
