A community health nurse is planning to use web-based information resources in the care of a client who is undergoing dialysis. Which of the following criteria should the nurse consider when selecting appropriate resources for the client?

Choice A reason: This is incorrect. Clostridium difficile is a bacterium that causes an infection of the colon, which can result in diarrhea, abdominal pain, and fever¹. Clostridium difficile is transmitted by contact with fecal matter or contaminated surfaces². Therefore, it requires contact precautions, not airborne precautions³.

Choice B reason: This is incorrect. Influenza is a viral infection that affects the respiratory tract, causing symptoms such as fever, cough, sore throat, and muscle aches⁴. Influenza is transmitted by respiratory droplets that are generated by coughing, sneezing, or talking⁵. Therefore, it requires droplet precautions, not airborne precautions³.

Choice C reason: This is correct. Disseminated herpes zoster is a widespread form of shingles that affects multiple areas of the skin and can involve the internal organs⁶. Shingles is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox⁷. Disseminated herpes zoster is transmitted by airborne particles that contain the virus, or by direct contact with the lesions⁶. Therefore, it requires airborne precautions, as well as contact precautions³.

Choice D reason: This is incorrect. Respiratory syncytial virus (RSV) is a common respiratory virus that causes mild to severe infections of the lungs and airways, especially in infants and young children⁸. RSV is transmitted by respiratory droplets, or by contact with contaminated surfaces or secretions⁹. Therefore, it requires contact precautions, and sometimes droplet precautions, but not airborne precautions³.

Choice A reason: Assessing the bladder for distention is an important action, but not the first one. The nurse should first check the uterine tone and position, as a boggy or displaced uterus can indicate uterine atony, the most common cause of postpartum hemorrhage.

Choice B reason: Massaging the client's fundus is the first action to take. The nurse should apply firm, circular pressure to the fundus to stimulate uterine contractions and reduce bleeding. The nurse should also monitor the amount and character of lochia.

Choice C reason: Preparing to administer a prescribed oxytocic preparation is a necessary action, but not the first one. The nurse should first attempt to control the bleeding by massaging the fundus and assessing the bladder. If the bleeding persists, the nurse should administer medications such as oxytocin, methylergonovine, or carboprost to enhance uterine contractions.

Choice D reason: Assessing the client's blood pressure is an important action, but not the first one. The nurse should first manage the bleeding by massaging the fundus and preparing to administer medications. The nurse should also monitor the client's vital signs, including blood pressure, pulse, and temperature, for signs of shock or infection
