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 C
Explanation
This is because the eyes of a deceased client do not close naturally and may remain open after death. Holding them shut for a few seconds helps to keep them closed and prevent drying of the corneas. This also gives a more peaceful appearance to the client’s body for the family visit.
Choice A is wrong because crossing the client’s arms across their chest is not a standard postmortem care procedure. It may also interfere with the placement of identification tags on the wrists.
Choice B is wrong because placing the client in a high-Fowler’s position is not necessary or appropriate for postmortem care. The client should be placed in a supine position with the head of the bed elevated to prevent livor mortis (purple discoloration of the skin) on the face.
Choice D is wrong because removing the client’s dentures from their mouth is not recommended for postmortem care. The dentures should be left in place to maintain the shape of the face and prevent the jaw from dropping.
Normal ranges are not applicable for this question as it does not involve any physiological measurements.
Correct Answer is D
Explanation
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.
