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.

Answer and Explanation

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 A

Explanation

The correct answer is Choice A.

Choice A rationale

Ignoring temper tantrums is an effective strategy for managing this behavior. By not giving attention to the tantrum, the child learns that this behavior will not achieve the desired outcome. This approach helps reduce the frequency and intensity of tantrums over time.

Choice B rationale

Restraining the child physically during a temper tantrum can escalate the situation and may cause injury to the child or the caregiver. It is not recommended as a strategy for managing temper tantrums.

Choice C rationale

Distracting the child by offering to play a game can be an effective strategy for preventing tantrums, but it is not the best approach once a tantrum has already started. Ignoring the tantrum is more effective in reducing the behavior over time.

Choice D rationale

Telling the child that temper tantrums are not acceptable may not be effective during the tantrum itself. The child is unlikely to be receptive to verbal reasoning during a tantrum. Ignoring the tantrum is a more effective strategy. .

A. Temper tantrums are a type of learning disability. B. You should leave the room while the tantrum is happening. C. You should get a psychological consult for the temper tantrums. D. Temper tantrums are the toddler’s attempt to gain control of a situation.

Correct Answer is D

Explanation

The correct answer is Choice D.

Choice A rationale

Temper tantrums are not a type of learning disability. They are a normal part of toddler development and are a way for toddlers to express frustration and assert independence.

Choice B rationale

Leaving the room while a tantrum is happening is not recommended. It is important for parents to stay calm and present, providing a safe environment for the child. Ignoring the tantrum while staying nearby can help the child learn to self-regulate.

Choice C rationale

Psychological consults are not typically necessary for temper tantrums. Temper tantrums are a normal part of development and usually decrease as the child learns to communicate and manage emotions better.

Choice D rationale

Temper tantrums are indeed the toddler’s attempt to gain control of a situation. Toddlers often have tantrums when they are unable to express their needs or when they are frustrated by their lack of control over their environment. Understanding this can help parents respond appropriately and support their child’s emotional development.
