A nurse is preparing to insert an IV catheter for a client.
Which of the following actions should the nurse plan to take?
Select a site on the client’s dominant arm
Apply a tourniquet below the venipuncture site
Elevate the client’s arm prior to insertion
Choose a vein that is palpable and straight
The Correct Answer is D
The correct answer is choice D. The nurse should choose a vein that is palpable and straight for IV catheter insertion.
This will facilitate the insertion of the catheter and reduce the risk of complications such as infiltration, phlebitis, or hematoma. A straight vein will also allow the catheter to be inserted up to the hub, which reduces the risk of contamination along the length of the catheter.
Choice A is wrong because selecting a site on the client’s dominant arm can interfere with the client’s mobility and increase the risk of dislodging the catheter. The nurse should choose a site on the client’s non-dominant arm, preferably on the hand or forearm.
Choice B is wrong because applying a tourniquet below the venipuncture site will impede blood flow and make it harder to locate a suitable vein. The nurse should apply a tourniquet above the venipuncture site, about 10 to 15 cm from the insertion site.
Choice C is wrong because elevating the client’s arm prior to insertion will decrease venous filling and make it harder to palpate a vein. The nurse should lower the client’s arm below the level of the heart to increase venous distension.
Normal ranges for IV catheter size and insertion angle depend on several factors, such as the type and duration of therapy, the condition and size of the vein, and the age and preference of the client.
In general, smaller gauge catheters (20 to 24) are preferred for peripheral IV therapy, and larger gauge catheters (14 to 18) are used for rapid fluid administration or blood transfusion. The insertion angle can vary from 10 to 30 degrees, depending on the depth and location of the vein.

Correct Answer is A
Explanation
The correct answer is choice A. Deep tendon reflexes 2+. This indicates that the client is receiving the therapeutic effect of magnesium sulfate, which is to prevent seizures by reducing neuromuscular excitability.
Magnesium sulfate is a mineral that is given intravenously to women with preeclampsia, a condition of high blood pressure and protein in the urine during pregnancy, to reduce the risk of seizures or eclampsia. It can also prolong pregnancy for up to two days, allowing drugs that speed up the baby’s lung development to be administered.
Choice B is wrong because 1+ proteinuria via urine dipstick is not a therapeutic effect of magnesium sulfate, but a sign of preeclampsia.
Proteinuria indicates that the kidneys are not working properly and are leaking protein into the urine. Magnesium sulfate does not improve the outcomes for the baby and can cause side effects such as respiratory depression for the mother.
Choice C is wrong because pulse rate 100/min is not a therapeutic effect of magnesium sulfate, but a possible side effect.
Magnesium sulfate can cause vasodilation, which lowers blood pressure and increases heart rate. A normal pulse rate for an adult is between 60 and 100 beats per minute. A pulse rate higher than 100 beats per minute may indicate tachycardia, which can be caused by various factors such as anxiety, dehydration, fever, infection, or medication.
Choice D is wrong because urine output 20 mL/hr is not a therapeutic effect of magnesium sulfate, but a sign of kidney failure. A normal urine output for an adult is between 800 and 2000 mL per day, or about 30 to 80 mL per hour. A urine output lower than 30 mL per hour may indicate oliguria, which can be caused by various factors such as dehydration, blood loss, shock, or kidney damage. Magnesium sulfate can cause renal toxicity if given in high doses or for prolonged periods.
Correct Answer is A
Explanation
Explanation:
"I will use a cool-mist vaporizer in my baby's room." This statement demonstrates an understanding of the teaching. Using a cool-mist vaporizer can help maintain moisture in the air and alleviate nasal congestion in infants.
Incorrect:
B- "I will leave my baby's bib on while he is sleeping." This statement indicates a lack of understanding. It is not safe to leave a bib on an infant while they are sleeping as it can pose a suffocation risk.
C- "I will leave the plastic covering on the crib mattress." This statement indicates a lack of understanding. The plastic covering on the crib mattress should be removed as it can pose a suffocation hazard.
D- "I will lay my baby's head on a pillow while he is in the crib." This statement indicates a lack of understanding. Pillows should not be used in the crib for infants as they can increase the risk of suffocation and SIDS (Sudden Infant Death Syndrome).
