A nurse is assessing a client who has asthma.
Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?
Conjunctivae.
Soles of the feet.
Oral mucosa.
Ear lobes.
The Correct Answer is C
The correct answer is Choice C.
Choice A rationale
The conjunctivae, the mucous membranes that cover the front of the eye and line the inside of the eyelids, can show signs of cyanosis. However, they are not the most reliable indicator of central cyanosis. Central cyanosis is best observed in areas with a rich blood supply and thin skin, where the bluish discoloration due to low oxygen levels in the blood is more apparent.
Choice B rationale
The soles of the feet are not a reliable indicator of central cyanosis. Peripheral cyanosis, which affects the extremities, can occur due to poor circulation or cold temperatures and does not necessarily indicate central cyanosis. Central cyanosis is more accurately assessed in areas with a high concentration of blood vessels and thin skin.
Choice C rationale
The oral mucosa, including the lips and tongue, is the most reliable indicator of central cyanosis. This area has a rich blood supply and thin skin, making it easier to observe the bluish discoloration caused by low oxygen levels in the blood. Central cyanosis is a sign of significant hypoxemia and requires prompt medical attention.
Choice D rationale
The ear lobes are not the most reliable indicator of central cyanosis. While they can show signs of cyanosis, they are not as accurate as the oral mucosa. The ear lobes may be affected by peripheral cyanosis, which can occur due to factors like cold temperatures or poor circulation, rather than central cyanosis.

Correct Answer is B
Explanation
The correct answer is Choice B.
Choice A rationale
Notifying the health care provider immediately may be necessary if the bleeding is severe or persistent. However, in the case of small amounts of blood, it is important to continue assessing for bleeding to determine if the situation worsens. Immediate notification may not be necessary for minor bleeding.
Choice B rationale
Continuing to assess for bleeding is the best intervention for a child spitting up small amounts of blood after a tonsillectomy. This allows the nurse to monitor the situation and determine if the bleeding is worsening or if it resolves on its own. It is important to keep the child calm and avoid any actions that could exacerbate the bleeding.
Choice C rationale
Encouraging the child to cough can increase the risk of further bleeding. Coughing can dislodge clots and cause additional trauma to the surgical site. It is important to keep the child calm and avoid actions that could worsen the bleeding.
Choice D rationale
Suctioning the back of the throat can cause additional trauma to the surgical site and increase the risk of bleeding. It is important to avoid invasive procedures and continue to assess for bleeding. If the bleeding worsens, further medical intervention may be necessary.
Correct Answer is D
Explanation
The correct answer is D. My child will take the enzymes to help digest the fat in foods.
Choice A rationale
Taking pancreatic enzymes following meals is not effective. The enzymes need to be taken with meals to aid in the digestion of food as it is being consumed.
Choice B rationale
Pancreatic enzymes are not taken to improve metabolism. They are specifically prescribed to aid in the digestion of fats, proteins, and carbohydrates in children with cystic fibrosis.
Choice C rationale
Taking pancreatic enzymes 2 hours before meals is not effective. The enzymes need to be taken with meals to ensure they are present in the digestive tract when food is being digested.
Choice D rationale
Taking pancreatic enzymes helps digest the fat in foods. Children with cystic fibrosis have difficulty digesting fats due to the thick mucus that blocks the pancreatic ducts, preventing the release of digestive enzymes
