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 a thick coat of calamine lotion over open lesions. B. Give diphenhydramine by mouth. C. Apply a cool cloth to the rash. D. Give ibuprofen or acetaminophen.

Correct Answer is C

Explanation

A. While calamine lotion can be soothing and help alleviate itching, applying a thick coat over open lesions is not advisable. It may not allow the skin to breathe and can potentially lead to further irritation or infection. Therefore, while this option has some merit, it is not the priority intervention.
B. Diphenhydramine (Benadryl) is an antihistamine that can help relieve itching. This option can be beneficial for managing pruritus and may help the child sleep better. However, while it can be useful, there are other interventions that can provide immediate comfort more effectively.
C. Applying a cool cloth to the rash is an immediate and effective way to provide comfort and relieve itching. The coolness can soothe inflamed skin and reduce the urge to scratch, which helps prevent secondary infections.
D. While giving ibuprofen or acetaminophen can help reduce fever and discomfort associated with varicella, it does not specifically address pruritus. These medications are helpful for pain management but are not the best choice for alleviating itching directly.
