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. Edema (swelling due to fluid accumulation) is not a primary manifestation of scabies. While secondary infections can lead to localized swelling, edema is not characteristic of scabies itself.
B. Maceration refers to the softening and breaking down of skin resulting from prolonged exposure to moisture. While it can occur if the skin is scratched and becomes wet, it is not a primary clinical manifestation of scabies.
C. Redness (erythema) can occur due to scratching and irritation, but it is not the defining feature of scabies. While some redness may be present, it is not the primary symptom that indicates scabies infestation.
D. The primary clinical manifestation of scabies is intense pruritus (itching), which is often worse at night. The itching is a result of an allergic reaction to the mites and their waste products, leading to discomfort and a strong urge to scratch.

A. Fever of more than 104°F and anorexia B. Headache and photophobia C. Fatigue. night sweats, and hemoptysis D. Chest and lower back pain

Correct Answer is C

Explanation

A. While fever and anorexia can occur with active TB, a fever of more than 104°F is uncommon. Typically, TB may cause a low-grade fever rather than such a high temperature. Anorexia is also present, but this option does not fully capture the classic symptoms of active TB.
B. These symptoms are not typical of tuberculosis. Headaches and photophobia are more associated with conditions affecting the central nervous system, such as meningitis or migraines. They do not specifically relate to active TB.
C. These symptoms are classic indicators of active tuberculosis. Fatigue and night sweats are common, and hemoptysis (coughing up blood) is a serious symptom that can occur in pulmonary TB. This combination of symptoms is a hallmark of the disease and would prompt further investigation.
D. While chest pain can occur due to lung involvement in TB, lower back pain is not a typical symptom of pulmonary TB. Chest pain might be experienced, but it is not as definitive as the other symptoms associated with active TB.
