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?
A. Dorsal surface of the foot
The dorsal surface of the foot may not be the best site for assessing cyanosis in a client with dark skin. Cyanosis can be more challenging to detect in individuals with darker skin tones due to the presence of melanin, which can mask the bluish color associated with cyanosis.
B. Dorsal surface of the hand
The dorsal surface of the hand is also not the most reliable site for assessing cyanosis in a client with dark skin. Again, the presence of melanin can make it more challenging to identify cyanosis in this area.
C. Pinnae of the ears
The pinnae of the ears is considered one of the more reliable sites for assessing cyanosis in individuals with dark skin. The skin in this area is thinner, and it is less affected by the presence of melanin. Therefore, any bluish discoloration may be more noticeable.
D. Conjunctivae
Examining the conjunctivae is a valid way to assess for cyanosis in individuals with all skin tones, including those with dark skin. However, this option does not specifically address the challenge of assessing cyanosis in a client with dark skin.

Full Explanation
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.

A nurse is preparing to perform hand hygiene. Which of the following actions should the nurse take?
A. Rub hands and arms to dry.
Rubbing hands and arms to dry is not the correct action for hand hygiene. After applying soap, hands should be rinsed thoroughly with water and then dried using a clean towel or air dryer.
B. Adjust the water temperature to feel hot.
Adjusting the water temperature to feel hot is not recommended for hand hygiene.Water that is too hot can be uncomfortable and may even cause skin irritation. The water should be comfortably warm.
C. Apply 4 to 5 mL of liquid soap to the hands.
Applying 4 to 5 mL of liquid soap to the hands is the correct action. This provides an adequate amount of soap to create a good lather for effective handwashing.
D. Hold the hands higher than the elbows.
Holding the hands higher than the elbows is not a necessary step for hand hygiene.The focus should be on thoroughly cleaning the hands, not on the position of the hands in relation to the elbows.

A nurse is teaching a client who has constipation. Which of the following should the nurse discuss as causes of constipation? (Select all that apply.)
A. Increased fiber in the diet
Increased fiber in the diet is not a cause of constipation, but rather a preventive measure that can help promote regular bowel movements by adding bulk and softness to the stool.
B. Ignoring the urge to defecate
Ignoring the urge to defecate is a cause of constipation, as it can lead to hardening and accumulation of fecal matter in the colon, resulting in difficulty and pain during defecation.
C. Inadequate fluid intake
Inadequate fluid intake is a cause of constipation, as it can contribute to dehydration and reduced stool moisture, making it harder and drier to pass.
D. Increased activity
Increased activity is not a cause of constipation, but rather a beneficial factor that can stimulate intestinal motility and facilitate bowel elimination.
E. Excessive laxative use
Excessive laxative use is a cause of constipation, as it can interfere with the normal functioning of the colon and cause dependence, leading to decreased bowel tone and reduced peristalsis.

C. Implementation
The Implementation phase involves carrying out the care plan. While it is important to be aware of allergies during this phase to ensure the safe administration of treatments, the initial identification of allergies occurs in the assessment phase.
D. Evaluation
The Evaluation phase involves assessing the client's response to interventions and determining if goals have been met. While allergies are relevant in evaluating the client's response to certain treatments, they are initially identified during the assessment phase.
