A nurse is assessing for cyanosis in a client who has dark skin. Which of the following sites should the nurse examine to identify cyanosis in this client?
Dorsal surface of the foot
Dorsal surface of the hand
Pinnae of the ears
Conjunctivae
The Correct Answer is D
A) The dorsal surface of the foot is not the most reliable site to assess for cyanosis in individuals with dark skin because the skin pigmentation can mask the bluish tint that indicates reduced oxygenation.
B) Similarly, the dorsal surface of the hand may not clearly show cyanosis due to the thickness and pigmentation of the skin, which can obscure the color change.
C) The pinnae of the ears may also not be the best indicator of cyanosis in dark-skinned individuals because peripheral areas like the ears can be affected by environmental temperatures, leading to misleading color changes.
D) The conjunctivae, however, are a mucous membrane where the skin pigmentation does not affect visibility. Therefore, it is an appropriate site for assessing cyanosis as it allows for the observation of subtle changes in color that indicate hypoxia. This is why the conjunctivae are the correct site to examine for cyanosis in a client with dark skin.

Correct Answer is ["B","C","D","E","F"]
Explanation
A. Potassium level is incorrect because it is within the normal range and does not affect wound healing directly.
B. Prealbumin level is correct because it is low, indicating malnutrition and poor protein intake, which are essential for tissue repair and immune function.
C. History of diabetes mellitus is correct because it causes impaired blood flow, increased risk of infection, and delayed inflammatory response, which all hinder wound healing.
D. History of hyperlipidemia is correct because it causes atherosclerosis and reduced blood supply to the affected area, which limits oxygen and nutrient delivery to the wound.
E. Wound infection is correct because it increases inflammation, tissue damage, and metabolic demands, which prolong the healing process and may lead to complications.
F. Decreased pedal perfusion is correct because it indicates poor circulation to the lower extremities, which impairs wound healing by reducing oxygen and nutrient delivery to
the wound.
G. Fasting blood glucose is incorrect because it is not a direct cause of delayed wound healing, but rather a reflection of the client's diabetes management. However, high blood glucose levels can impair wound healing by affecting blood flow, immune function, and collagen synthesis.
Correct Answer is B
Explanation
A. Lactated Ringer's is a balanced electrolyte solution, but it contains sodium in a similar concentration to normal serum levels. It is not appropriate for a client with hypernatremia, as it could further increase their sodium levels.
B. 0.45% sodium chloride, also known as half-normal saline, is a hypotonic solution with a lower concentration of sodium than normal serum levels. It can help to lower the sodium levels in a client with hypernatremia by diluting the excess sodium in the body.
C. Dextrose 5% in 0.9% sodium chloride is a hypertonic solution that contains both dextrose and sodium. It would not be appropriate for a client with hypernatremia, as it could exacerbate the condition.
D. Dextrose 10% in water is a hypertonic solution with a high concentration of dextrose.
It does not contain sodium, but it is still a hypertonic solution and not appropriate for a client with hypernatremia.
