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 C
Explanation
Nitroglycerin transdermal patches are used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart). They work by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen.
Choice A is wrong because nitroglycerin transdermal patches cannot be used to treat an attack of angina once it has begun. They can only be used to prevent attacks of angina. If you have chest pain, you should use another form of nitroglycerin, such as sublingual tablets or spray.
Choice B is wrong because headache is a common side effect of nitroglycerin transdermal patches and does not mean that you should stop using them. However, you should tell your doctor if the headaches are severe or do not go away. You may also take acetaminophen to relieve the headache.
Choice D is wrong because you do not need to cover the patch with dry gauze when taking a shower. You may shower while you are wearing a nitroglycerin skin patch. If a patch loosens or falls off, replace it with a fresh one.
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.
