The nurse notes that a client has ataxi

Plantar flexion

Romberg

Achilles reflex

Patellar reflex

Answer and Explanation

The Correct Answer is B

Choice A reason: Plantar flexion is not a test that the nurse uses to gain more information about this client's gait because it is a movement of the foot that points the toes downward, not a measure of balance or coordination.

Choice B reason: Romberg is a test that the nurse uses to gain more information about this client's gait because it is a measure of balance and proprioception, which are often impaired in ataxiA. The test involves asking the client to stand with their feet together and arms at their sides, first with their eyes open and then with their eyes closed, while observing for swaying or fallinG.

Choice C reason: Achilles reflex is not a test that the nurse uses to gain more information about this client's gait because it is a measure of the reflex response of the calf muscle when the Achilles tendon is tapped, not a measure of balance or coordination.

Choice D reason: Patellar reflex is not a test that the nurse uses to gain more information about this client's gait because it is a measure of the reflex response of the quadriceps muscle when the patellar tendon is tapped, not a measure of balance or coordination.

Correct Answer is B

Explanation

Choice A reason: Advances in surgical techniques and procedures have improved the quality of life and survival rates for many patients, but they are not the main factor for the increase in life expectancy in the twentieth century.

Choice B reason: Sanitation and other public health activities, such as vaccination, safe water supply, sewage disposal, and food safety, have reduced the incidence and mortality of infectious diseases, which were the leading causes of death in the past. These activities have had a significant impact on increasing life expectancy in the twentieth century.

Choice C reason: Technology increases in the field of medical laboratory research have enabled better diagnosis and treatment of diseases, but they are not the primary reason for the increase in life expectancy in the twentieth century.

Choice D reason: Use of antibiotics to fight infections has saved many lives and prevented complications from bacterial diseases, but they are not the most important factor for the increase in life expectancy in the twentieth century. Moreover, antibiotics were not widely available until after World War II, which means they did not contribute much to the increase in life expectancy before that perioD.

A. A negative-pressure isolation room B. A positive-pressure isolation room C. A private room D. A semi-private room with a client who has pediculosis capitis

Correct Answer is C

Explanation

Choice A reason: A negative-pressure isolation room is not appropriate for this client because it is used for clients who have airborne infections that can spread through small droplets that remain suspended in the air, such as tuberculosis, measles, or chickenpox. Scabies is a skin infection that is spread by direct contact with infested skin or clothinG.

Choice B reason: A positive-pressure isolation room is not appropriate for this client because it is used for clients who have compromised immune systems and need protection from environmental contaminants, such as bone marrow transplant recipients, burn victims, or organ transplant recipients. Scabies is not caused by environmental contaminants, but by parasitic mites that burrow under the skin.

Choice C reason: A private room is appropriate for this client because it prevents contact transmission of scabies to other clients or stafF. The client should also have dedicated equipment and linens, and wear gloves and gown when leaving the room. The room should be thoroughly cleaned and disinfected after the client's dischargE.

Choice D reason: A semi-private room with a client who has pediculosis capitis is not appropriate for this client because it increases the risk of cross-contamination between the two clients. Pediculosis capitis is a head lice infestation that can also be spread by direct contact with infested hair or personal items.
