A charge nurse is teaching new staff members about factors that increase a client’s risk to become violent.

Which of the following risk factors should the nurse include as the best predictor of future violence?

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.

The correct answer is choicea. Swelling of the face.

Choice A rationale:

Swelling of the face can be a sign of preeclampsia, a serious condition that requires immediate medical attention.Preeclampsia can lead to complications for both the mother and the baby if not managed properly.

Choice B rationale:

Urinary frequency is a common symptom during pregnancy due to hormonal changes and the growing uterus pressing on the bladder.It is generally not a cause for concern unless accompanied by other symptoms like pain or burning during urination.

Choice C rationale:

Faintness upon rising, also known as orthostatic hypotension, is common in pregnancy due to changes in blood circulation.It can often be managed by rising slowly and ensuring adequate hydration.

Choice D rationale:

Bleeding gums are common during pregnancy due to hormonal changes that increase blood flow to the gums, making them more sensitive and prone to bleeding.Good oral hygiene can help manage this symptom.
