A nurse is assisting with the admission of a client who has meningococcal pneumonia. Which of the following isolation precautions should the nurse initiate?

Choice A reason: Moderate fatigue typically encourages sleep as the body naturally seeks rest to recover. However, if fatigue is excessive, it might lead to an overtired state where the patient finds it difficult to relax and fall asleep. Normal ranges of physical activity and resulting fatigue can actually promote better sleep patterns by helping to regulate the body's natural sleep-wake cycle.

Choice B reason: The ability to talk about the day's events can be therapeutic and help in reducing stress levels. It allows the patient to process emotions and experiences, potentially leading to a calmer state of mind which is conducive to sleep. This is particularly true if the conversation is positive or neutral rather than rehashing stressful or traumatic events.

Choice C reason: The presence of pain is a significant factor that can disrupt sleep. Pain can make it difficult for a person to find a comfortable position for sleep, and it can cause frequent awakenings or prevent the patient from falling asleep altogether. Pain management should be a priority in patient care, especially at night, to facilitate better sleep. For instance, arthritis pain can be particularly disruptive due to joint discomfort, and addressing this with appropriate pain relief can greatly improve sleep quality.

Choice D reason: While unfamiliar stimuli can disrupt sleep, their absence is not typically a factor that would negatively affect sleep patterns. In fact, a lack of unfamiliar stimuli, meaning a quiet and consistent environment, is generally beneficial for sleep as it reduces the chances of disturbances.

Choice A reason: Scarlet fever is caused by a bacterium that produces a toxin leading to a rash. It is typically spread through respiratory droplets, and while standard precautions are necessary, an N95 respirator is not required.

Choice B reason: Tuberculosis is an airborne infectious disease that requires the use of an N95 respirator to protect against inhaling the bacteria, especially in cases of pulmonary tuberculosis. This type of respirator filters out at least 95% of airborne particles, including Mycobacterium tuberculosis.

Choice C reason: Mycoplasmal pneumonia, also known as "walking pneumonia," is caused by Mycoplasma pneumoniae and is typically less severe than other types of bacterial pneumonia. Standard precautions, including the use of surgical masks, may be sufficient unless there is a risk of aerosol-generating procedures.

Choice D reason: Scabies is caused by a mite that burrows into the skin. It is spread through direct skin-to-skin contact, and an N95 respirator is not needed for protection against scabies.
