A nurse is positioning a client for a cesarean birth. To prevent a compromise in placental blood flow during the intraoperative period, which of the following actions should the nurse take?

Insert a pillow under the client’s knees.

Position the client in reverse Trendelenburg.

Assist the client in the lithotomy position.

Place a wedge under one of the client’s hips.

Answer and Explanation

The Correct Answer is D

This is because placing a wedge under one of the hips can help prevent compression of the inferior vena cava by the uterus, which can compromise placental blood flow and cause fetal hypoxia. Placing a wedge under the hip can also help reduce the risk of maternal hypotension, which can also affect fetal oxygenation.
Choice A is wrong because inserting a pillow under the client’s knees can increase the risk of thromboembolism, which is a potential complication of cesarean birth.
Choice B is wrong because positioning the client in reverse Trendelenburg can increase the risk of maternal aspiration, which is another potential complication of cesarean birth.
Choice C is wrong because assisting the client into the lithotomy position can also compress the inferior vena cava and reduce placental blood flow. The lithotomy position is also not necessary for cesarean birth, as the baby is delivered through an incision in the abdomen and uterus.

Correct Answer is D

Explanation

A noncoring needle is a special type of needle that has a beveled tip and a side hole. It is designed to prevent damage to the port’s septum, which is the soft silicone top that serves as the vein access point. A noncoring needle also reduces the risk of infection and clotting.

Choice A is wrong because a butterfly needle is a small, winged needle that is used for peripheral venous access, not for accessing a port. A butterfly needle can damage the port’s septum and cause leakage or infection.

Choice B is wrong because an angiocatheter is a thin, plastic tube that is inserted into a vein using a needle.

It is used for short-term IV therapy, not for accessing a port. An angiocatheter can also damage the port’s septum and cause complications.

Choice C is wrong because a 25-gauge needle is too small to access a port.

A 25-gauge needle is typically used for subcutaneous injections, not for intravenous injections. A 25-gauge needle can also clog the port or cause hemolysis (breakdown of red blood cells).

Normal ranges for ports vary depending on the type and size of the port, but generally they have a reservoir diameter of 1.5 to 2.5 cm, a catheter length of 40 to 60 cm, and a catheter diameter of 0.8 to 1.2 mm. Ports are usually flushed with saline or heparin solution every 4 to 6 weeks when not in use to prevent clotting.

A. Administer a fluid bolus. B. Initiate continuous bladder irrigation. C. Obtain a urine specimen for culture and sensitivity. D. Clamp the catheter tubing for 30 min.

Correct Answer is A

Explanation

The client has signs of dehydration and oliguria, which are low urine output and dark yellow urine. A fluid bolus can help restore the fluid balance and improve the renal perfusion. The normal urine output for an adult is 0.5-1.5 mL/kg/hr, and the client’s urine output is only 25 mL/hr, which is below the minimum acceptable level. Dark yellow urine can indicate a high concentration of waste products and a low intake of fluids.

Choice B is wrong because continuous bladder irrigation is used to prevent or treat blood clots in the bladder after surgery or injury, not to increase urine output.

Choice C is wrong because a urine specimen for culture and sensitivity is used to diagnose a urinary tract infection, which is not the most likely cause of the client’s low urine output.

The client does not have other symptoms of infection, such as fever, pain, or cloudy urine.

Choice D is wrong because clamping the catheter tubing for 30 min can cause urinary retention, bladder distension, and increased risk of infection.

It can also interfere with the accurate measurement of urine output.
