A nurse is preparing to administer vancomycin 500 mg via intermittent IV infusion every 6 hr. Available is vancomycin 500 mg in 0.9% sodium chloride 100 mL to infuse over 2 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

Choice A rationale:

Instructing the client's loved ones that the client should not have fresh flowers in their room (Choice A) is not a necessary action for rubella isolation. Rubella is transmitted through respiratory droplets, and the prohibition of fresh flowers is not a relevant precaution.

Choice B rationale:

Wearing a surgical mask when within 0.9 m (3 feet) of the client (Choice B) is the correct action. Rubella is an airborne disease, and wearing a surgical mask helps prevent the spread of infectious respiratory droplets to the nurse and other individuals.

Choice C rationale:

Placing the client in a room with negative-airflow pressure (Choice C) is not specifically indicated for rubella isolation. Negative-airflow pressure rooms are typically used for diseases that require strict airborne precautions, such as tuberculosis.

Choice D rationale:

Instructing the client that visitors will not be allowed while they are in isolation (Choice D) is not entirely accurate for rubella isolation. While isolation precautions are necessary, visitors can enter the room if they are properly protected, including wearing masks and following infection control protocols.

Choice A rationale:

Increased sensitivity to touch is not an expected physiological change associated with aging. Older adults often experience decreased sensitivity to touch due to changes in nerve endings and decreased skin elasticity. This can lead to decreased sensation rather than increased sensitivity.

Choice B rationale:

Decreased peripheral circulation is an expected physiological change associated with aging. With age, blood vessels can become less elastic and more narrow, leading to reduced blood flow to the extremities. This can result in cold extremities, delayed wound healing, and increased vulnerability to skin breakdown. Nurses should assess for signs of impaired circulation in older adult clients and provide appropriate interventions to prevent complications.

Choice C rationale:

Decreased airway resistance is not an expected physiological change associated with aging. Older adults often experience increased airway resistance due to changes in lung elasticity and chest wall compliance. This can lead to decreased lung function and a higher risk of respiratory issues such as pneumonia and bronchitis.

Choice D rationale:

Increased appetite is not an expected physiological change associated with aging. In fact, many older adults experience a decrease in appetite due to factors such as changes in metabolism, decreased sense of taste and smell, and underlying health conditions. This reduced appetite can contribute to malnutrition and weight loss in the elderly population.
