The nurse is examining an elderly client and notes an exaggerated curvature of the thoracic spine.
The nurse should document this finding as which of the following?
Lordosis.
Scoliosis.
Spinal dysplasia.
Kyphosis.
The Correct Answer is D
Choice A rationale
Lordosis refers to an excessive inward curvature of the lumbar spine, often referred to as swayback. This condition causes the lower back to arch more than normal, leading to a prominent abdomen and buttocks. Lordosis does not affect the thoracic spine and does not cause an exaggerated curvature in that region.
Choice B rationale
Scoliosis is a lateral curvature of the spine that results in an S- or C-shaped curve. It can occur in the thoracic, lumbar, or cervical regions of the spine. Scoliosis involves a sideways deviation rather than an exaggerated curvature in the thoracic spine.
Choice C rationale
Spinal dysplasia is a broad term that refers to various congenital abnormalities affecting the development of the spine. It includes conditions such as spina bifida, kyphosis, and scoliosis, each with distinct characteristics. The term itself does not specify an exaggerated thoracic curvature.
Choice D rationale
Kyphosis is an exaggerated outward curvature of the thoracic spine, resulting in a rounded or hunched back appearance. This condition is common in elderly individuals and can be caused by factors such as osteoporosis, vertebral fractures, or degenerative changes. It leads to a noticeable forward bend of the upper back.

Correct Answer is D
Explanation
Choice A rationale
Atrial depolarization refers to the electrical activation of the atria, which is depicted by the P wave on an ECG, not the T wave. The P wave represents the contraction phase of the atria as it pumps blood into the ventricles. Therefore, this option is incorrect for the T wave.
Choice B rationale
Atrial repolarization is the process of the atria returning to their resting state. This repolarization is generally obscured by the QRS complex on an ECG and is not associated with the T wave. Thus, this answer choice is also incorrect.
Choice C rationale
Ventricular depolarization is represented by the QRS complex on an ECG. It indicates the ventricles are contracting to pump blood to the lungs and the rest of the body. Therefore, it does not correlate with the T wave.
Choice D rationale
Ventricular repolarization is indicated by the T wave on an ECG. This phase signifies the ventricles returning to their resting state after the contraction. It is the correct answer as it accurately reflects the T wave's function.
Correct Answer is A
Explanation
Choice A rationale
Pallor refers to the pale appearance of the skin due to decreased blood flow or decreased hemoglobin levels. It is often seen in conditions such as anemia, where there is a reduced number of red blood cells or hemoglobin, leading to a lack of the red-pink tones normally present in healthy skin.
Choice B rationale
Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is often seen in respiratory or cardiovascular conditions where there is a decrease in oxygen levels. Cyanosis does not describe the absence of red-pink tones from decreased hemoglobin.
Choice C rationale
Jaundice refers to a yellow discoloration of the skin and eyes due to elevated levels of bilirubin in the blood. It is often seen in liver conditions or hemolysis. Jaundice is not related to decreased hemoglobin levels or the absence of red-pink tones in the skin.
Choice D rationale
Erythema refers to redness of the skin caused by increased blood flow to the capillaries in the dermis. It is often associated with inflammation, infection, or skin irritation. Erythema indicates increased blood flow, not decreased hemoglobin levels.
