A nurse is caring for a client who has an implanted venous access port.
Which of the following should the nurse use to access the port?
butterfly needle
An angiocatheter
A 25-gauge needle
A noncoring needle
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A reason
Abdomen area is not appropriate: Assessing skin turgor on the abdomen is not commonly performed. The abdomen may not be the most accurate site for assessing skin turgor, especially in older adults, as it can be influenced by factors such as body fat distribution.
Choice B reason:
Shoulder are is not appropriate: The shoulder is not a typical site for assessing skin turgor. It is generally not used for this purpose, as it may not provide reliable results
Choice C reason:
Stomach is not the correct answer.: Assessing skin turgor on the stomach is also not commonly performed. The abdomen or stomach may not be the most accurate site for assessing skin turgor, especially in older adults.
Choice D reason
When assessing skin turgor in an older adult client, the nurse should lift the skin on the neck to evaluate its elasticity and hydration status. Skin turgor is a measure of skin's elasticity and is commonly used as an indicator of hydration in both adults and older adults.
To assess skin turgor, the nurse will gently pinch a small amount of skin on the back of the client's hand or the front of the chest (sternum). However, since the options listed do not include these areas, the closest alternative for an older adult would be the neck.
Correct Answer is A
Explanation
- Answer and explanation.
The correct answer is choice A. Increased Hct.
Hct stands for hematocrit, which is the percentage of red blood cells (RBCs) in the blood.
A client who received 2 units of packed RBCs should have an increased Hct because they have more RBCs in their blood volume. The normal range for Hct is 38% to 50% for males and 36% to 44% for females.
Choice B is wrong because decreased Hgb means decreased hemoglobin, which is the protein that carries oxygen in the RBCs.
A client who received 2 units of packed RBCs should have an increased Hgb because they have more hemoglobin in their blood. The normal range for Hgb is 13.5 to 17.5 g/dL for males and 12 to 15.5 g/dL for females.
Choice C is wrong because increased platelets means increased thrombocytes, which are the cells that help with blood clotting.
A client who received 2 units of packed RBCs should not have an increased platelet count because they did not receive platelets in the transfusion. The normal range for platelets is 150,000 to 400,000/mm^3.
Choice D is wrong because decreased WBC count means decreased leukocytes, which are the cells that fight infection and inflammation.
A client who received 2 units of packed RBCs should not have a decreased WBC count because they did not receive WBCs in the transfusion. The normal range for WBC count is 4,500 to 11,000/mm^3.
