The nurse is aware the early indicator of hypoxia in the unconscious client is:

Cyanosis

Restlessness

Increased respirations

Hypertension

Answer and Explanation

The Correct Answer is B

A.   Cyanosis is a late sign of hypoxia, occurring when oxygen saturation is significantly low. It's often visible in the mucous membranes and skin.
B.   Restlessness is often one of the earliest signs of hypoxia. As oxygen levels decrease, the brain becomes deprived of oxygen, leading to changes in mental status, including restlessness, confusion, and agitation.
C.   Increased respirations (tachypnea) can be a sign of hypoxia, but it's often a later response as the body attempts to compensate for decreased oxygen levels.
D.   Hypertension is not a typical sign of hypoxia. In fact, severe hypoxia can lead to hypotension as blood pressure decreases.

Correct Answer is D

Explanation

A. Congenital cataracts are present at birth and are relatively rare. In older adults, cataracts are primarily associated with age-related changes rather than congenital factors.
B. While certain medications used to treat asthma, like corticosteroids, can contribute to the development of cataracts, asthma itself is not a direct cause of cataracts. This connection is not strong enough to be considered a common cause.
C. While eye injuries can lead to cataract formation, they are not the most common cause, especially in the older adult population. Most cataracts develop due to age-related changes rather than trauma.
D. The most prevalent cause of cataracts, especially in older adults, is aging. As people get older, changes in the lens of the eye can lead to clouding, resulting in cataracts. Factors like UV exposure, smoking, and certain medical conditions may also contribute, but aging is the primary and most common factor.

A. Apply topical corticosteroids to decrease inflammation. B. Maintain contact precautions. C. Examine child under a wood lamp for possible spread of lesions. D. Carefully remove dressings to not dislodge damaged skin, crusts, and debris.

Correct Answer is B

Explanation

A. Topical corticosteroids are not typically used for impetigo, as it's a bacterial infection.
B. Impetigo is highly contagious, so contact precautions are essential to prevent the spread of infection. This includes wearing gloves and a gown when providing direct care, and using dedicated equipment for the child.
C. A wood lamp is used to examine the skin for fungal infections, not bacterial infections like impetigo.
D. Impetigo typically doesn't require dressings. If dressings are used, they should be removed gently to avoid further skin damage.
