A nurse is performing a skin assessment on a client who has dark skin.
Which of the following locations on the client’s body should the nurse observe to assess for cyanosis?
Area of trauma.
Sacrum.
Shoulders.
Palms of the hands.
The Correct Answer is D

Cyanosis is a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is more difficult to detect in people who have dark skin, so the nurse should look for cyanosis in areas where the skin is thinner and the blood supply is richer, such as the palms of the hands, the lips, the gums, and around the eyes.
These areas are less affected by melanin, the pigment that gives skin its color.
Choice A is wrong because an area of trauma may have bruising or inflammation that can mask cyanosis.
Choice B is wrong because the sacrum is not a good site to assess for cyanosis in any skin tone, as it is prone to pressure ulcers and poor circulation.
Choice C is wrong because the shoulders are not a mucous membrane and may have more melanin than other areas of the body.

Correct Answer is D
Explanation
The correct answer is choice D, a noncoring needle.
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.

Explanation
The nurse should recognize the client is experiencing preterm labor due to previous preterm birth.
Preterm labor is when regular contractions begin to open the cervix before 37 weeks of pregnancy. One of the risk factors for preterm labor is having a previous preterm delivery. The client’s history indicates that her last pregnancy resulted in a preterm spontaneous vaginal birth at 30 weeks gestation. The client’s current symptoms, such as lower back pain, pinkish vaginal discharge, uterine contractions and cervical dilation, also suggest that she is in preterm labor. Therefore, the nurse should recognize that the client is experiencing preterm labor due to previous preterm birth.
BMI, blood type and blood pressure are not causes of preterm labor in this case. BMI may be associated with preterm labor if it is too high or too low, but the client’s BMI is within the normal range for pregnancy. Blood type may cause Rh incompatibility if the mother is Rh negative and the baby is Rh positive, but the client’s blood type is Rh positive. Blood pressure may cause preeclampsia if it is too high, but the client’s blood pressure is normal. Abruptio placentae is a condition where the placenta separates from the uterine wall before delivery, which can cause vaginal bleeding, abdominal pain and fetal distress. The client does not have these signs.
