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.

Answer and Explanation

The Correct Answer is D

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 B

Explanation

Bradypnea is abnormally slow breathing, which can be a sign of life-threatening respiratory depression caused by morphine. Respiratory depression is the most serious adverse effect of morphine and can lead to coma and death if not treated promptly. Therefore, the nurse should monitor the child’s respiratory rate and oxygen saturation closely and be prepared to administer naloxone, an opioid antagonist, if needed.

Choice A is wrong because euphoria is a feeling of intense happiness or well-being that is a common side effect of morphine.

Euphoria is not a priority finding and does not indicate a serious complication of morphine.

Choice C is wrong because constipation is a common and chronic side effect of morphine that affects the gastrointestinal system.

Constipation can cause discomfort and complications such as bowel obstruction, but it is not a priority finding compared to respiratory depression.

Choice D is wrong because sedation is another common side effect of morphine that affects the central nervous system.

Sedation can impair the child’s level of consciousness and ability to respond to stimuli, but it is not as urgent as respiratory depression.

A. Nausea. B. Polyhydramnios. C. Uterine tenderness. D. Spotting.

Correct Answer is D

Explanation

Placenta previa is a condition where the placenta implants in the lower part of the uterus, partly or completely covering the cervical opening.

This can cause painless, bright red vaginal bleeding, usually in the third trimester. Spotting is a sign of placenta previa and should be reported to the provider immediately. Choice A is wrong because nausea is not a specific finding of placenta previa.

Nausea can occur in normal pregnancy or in other conditions such as hyperemesis gravidarum or preeclampsia.

Choice B is wrong because polyhydramnios is not a finding of placenta previa.

Polyhydramnios is a condition where there is too much amniotic fluid in the uterus, which can cause complications such as preterm labor, cord prolapse, or fetal malformations.

Choice C is wrong because uterine tenderness is not a finding of placenta previa.

Uterine tenderness is a sign of abruptio placentae, which is a condition where the placenta separates from the uterine wall before delivery.

This can cause severe abdominal pain, dark red vaginal bleeding, and fetal distress.
