A client taking rosuvastatin presents with severe weakness and difficulty moving. What condition might the nurse suspect?

The scenario describes a client on rosuvastatin experiencing severe weakness and difficulty moving, which raises suspicion for rhabdomyolysis. This condition is a serious side effect associated with the use of statins, including rosuvastatin. Rhabdomyolysis occurs when there is significant muscle damage, leading to the release of muscle cell contents into the bloodstream, which can be harmful to the kidneys and other organs.

The symptoms of rhabdomyolysis often include severe muscle pain, weakness, and swelling, as well as symptoms like dark-colored urine due to the presence of myoglobin. Given the specific symptoms presented, it aligns strongly with rhabdomyolysis rather than other options.

Other conditions such as cholecystitis and cholelithiasis are related to gallbladder issues and are less likely to present with muscle weakness and mobility difficulties. Pruritis, which refers to severe itching, is also not consistent with the muscle-related symptoms described. Understanding these specifics helps categorize the symptoms accurately, confirming rhabdomyolysis as the condition of concern in this scenario.
