A nurse is caring for a client who is postoperative following knee arthroplasty and has a new prescription for enoxaparin 1mg/kg subcutaneous. The client weighs 185 lb. How many mg should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. "Pyelonephritis increases a person's risk for kidney damage." - Pyelonephritis is a bacterial infection of the renal parenchyma and renal pelvis, typically caused by the ascent of bacteria from the lower urinary tract into the kidneys. If left untreated, it can lead to kidney damage, including scarring of the renal tissue and impaired kidney function.

B. "Pyelonephritis is an infection of the lower urinary tract." - This statement is incorrect. Pyelonephritis specifically involves the upper urinary tract, affecting the kidneys. In contrast, infections of the lower urinary tract (such as cystitis) affect the bladder and urethra.

C. "Pyelonephritis often causes no symptoms in affected clients." - This statement is incorrect. Pyelonephritis typically presents with symptoms such as fever, chills, flank pain, painful urination (dysuria), and frequent urination. Clients with pyelonephritis usually experience noticeable symptoms.

D. "Pyelonephritis is most often caused by Staphylococcus saprophyticus." - This statement is incorrect. While Staphylococcus saprophyticus is a common cause of urinary tract infections, pyelonephritis is more commonly caused by gram-negative bacteria, such as Escherichia coli, which often ascend from the lower urinary tract into the kidneys.

A. Avoiding the use of ice packs to treat muscle pain - While ice packs can cause skin damage in older adults with thinning skin, it is not the most appropriate response to the question. Protecting against shearing injuries is a more direct and specific concern related to thinning skin.

B. Protecting older adults against excessive sweat accumulation - Excessive sweat accumulation can lead to skin irritation, but this option does not directly address the issue of thinning skin as the primary concern in the question.

C. By protecting older adults against shearing injuries
Thinning skin in older adults makes them more vulnerable to skin injuries, especially shearing injuries. Shearing occurs when the skin is pulled in one direction while the underlying bone and tissues are pulled in the opposite direction. This can lead to skin tears and other wounds, which can be painful and slow to heal in older adults. Nurses should take special precautions to prevent shearing injuries, such as using lift sheets or sliding devices when moving patients, and ensuring that patients are repositioned frequently to reduce friction and shearing forces.

D. Avoiding the use of lotion on older adults' skin - Proper moisturization of the skin is important, especially in older adults, to prevent dryness and skin breakdown. Avoiding lotion is not a recommended practice; instead, choosing appropriate, non-irritating lotions can help maintain skin integrity.
