A nurse is planning care of a group of clients at the beginning of their shift. Which of the following clients should the nurse care for first?

A. A client who has a history of MRSA will need antibiotics: Not all clients with a history of MRSA require antibiotics; treatment is only necessary if there is an active infection. Prophylactic antibiotics are not indicated solely based on past MRSA colonization or infection.

B. A client who has a history of MRSA can develop immunity to the infection: There is no immunity conferred by a past MRSA infection. Clients can be colonized or reinfected, and immunity does not prevent future transmission or infection.

C. A client who has a history of MRSA requires a protective environment: Protective environment precautions are used for immunocompromised clients to prevent them from acquiring infections, not for clients with MRSA history. MRSA requires standard and contact precautions, not protective isolation.

D. A client who has a history of MRSA can still transmit the infection: Clients with a history of MRSA may remain colonized and can transmit the bacteria to others, even if asymptomatic. Adhering to contact precautions and proper hand hygiene is essential to prevent spread within healthcare settings.

A. Bedtime: The client’s bedtime of 2330 has remained unchanged despite the shift in work hours, providing some stability to the circadian rhythm. A consistent bedtime typically supports sleep regulation rather than disrupting it. Although the new routine may affect sleep pressure, the bedtime is not the primary contributor to the new difficulties falling asleep.

B. Use of chronic devices: The client turns off their phone at 2230, limiting blue-light exposure well before bedtime. There is no indication of prolonged screen use or other electronic stimulation that would interfere with melatonin release. With the device turned off an hour before bed, this factor is unlikely to be influencing the client’s disrupted sleep.

C. Evening meal: The client now eats dinner late in the evening after a 1200–2000 work shift, placing the meal close to their 2330 bedtime. Eating late can increase gastrointestinal activity and delay the body’s transition into restful sleep, contributing to both difficulty falling asleep and nighttime awakenings.

D. Medication: The client’s medications ethinyl estradiol/desogestrel and ferrous sulphate have remained consistent for months without changes in timing or dosage. These medications are not known to disrupt sleep when taken as prescribed and do not coincide with the recent onset of nighttime symptoms.

E. Caffeine use: Although the client now drinks 2 to 3 cups of coffee, it is consumed early in the morning and remains outside the usual window in which caffeine impacts nighttime sleep. Morning intake allows adequate time for caffeine metabolism before bedtime. The timing makes it a less significant factor in the client’s difficulties initiating and maintaining sleep.

F. Exercise schedule: The client exercises immediately after a shift that ends at 2000, pushing vigorous activity close to bedtime. Late-evening exercise can increase sympathetic activity and core body temperature, which can interfere with the body’s ability to relax and initiate sleep.
