A client presents to a clinic complaining of a leg ulcer that isn't healing; subsequent diagnostic testing suggests osteomyelitis. The nurse is aware the most common pathogen to cause osteomyelitis is which pathogen?
Staphylococcus aureus
Escherichia coli
Proteus mirabilis
Pseudomonas aeruginosa
None of the above
The Correct Answer is A
Choice A reason: Staphylococcus aureus is the most common pathogen to cause osteomyelitis, as it is a gram-positive bacterium that can invade the bone through the bloodstream, a wound, or a surgical site. It can cause acute or chronic inflammation and infection of the bone and bone marrow.
Choice B reason: Escherichia coli is not the most common pathogen to cause osteomyelitis, as it is a gram-negative bacterium that is usually found in the gastrointestinal tract. It can cause urinary tract infections, diarrhea, or sepsis, but it is not a frequent cause of bone infections.
Choice C reason: Proteus mirabilis is not the most common pathogen to cause osteomyelitis, as it is a gram-negative bacterium that is usually found in the urinary tract. It can cause urinary tract infections, kidney stones, or septicemia, but it is not a common cause of bone infections.
Choice D reason: Pseudomonas aeruginosa is not the most common pathogen to cause osteomyelitis, as it is a gram-negative bacterium that is usually found in moist environments. It can cause skin infections, pneumonia, or septic shock, but it is not a frequent cause of bone infections.
Choice E reason: None of the above is not a correct choice, as there is one option that matches the most common pathogen to cause osteomyelitis.

Correct Answer is A
Explanation
Choice A reason: This statement is incorrect and indicates the need for further education. Failure to rescue is not the ability of the nurse to save a client's life, but the inability or failure to do so. It is defined as the death of a hospitalized client who experienced a potentially preventable complication.
Choice B reason: This statement is correct and does not indicate the need for further education. Failure to rescue includes the failure of the nurse to report changes in a client's condition to the provider, which could delay the diagnosis and treatment of the complication.
Choice C reason: This statement is correct and does not indicate the need for further education. Failure to rescue is the failure to recognize a client's condition is deteriorating, which could lead to missed opportunities for intervention and prevention of adverse outcomes.
Choice D reason: This statement is correct and does not indicate the need for further education. Failure to rescue involves the lack of managing complications, which could result in increased morbidity and mortality.
Correct Answer is C
Explanation
Choice A reason: Transferring from sitting to standing position is not a high-risk activity for hip dislocation, as long as the client follows the proper precautions, such as keeping the operated leg slightly forward, using a chair with armrests, and avoiding twisting or pivoting the hip.
Choice B reason: Straining during a bowel movement is not a direct risk factor for hip dislocation, but it may cause constipation, which is a common problem after surgery. The nurse should educate the client on the importance of adequate hydration, fiber intake, and stool softeners to prevent constipation and reduce the need for straining.
Choice C reason: Bending down to put socks on is a risky activity for hip dislocation, as it violates the hip precautions of avoiding flexing the hip more than 90 degrees, adducting the hip, or internally rotating the hip. The nurse should instruct the client to use assistive devices, such as a sock aid or a long-handled reacher, to put on socks or shoes without bending the hip.
Choice D reason: Turning in bed with an abductor pillow in place is a safe activity for hip dislocation, as the abductor pillow helps to maintain the alignment and stability of the hip joint. The nurse should teach the client to use the abductor pillow while in bed for the first few weeks after surgery, and to turn from side to side with the assistance of a caregiver.
Choice E reason: Crossing the legs or ankles is a dangerous activity for hip dislocation, as it causes the hip to move out of its normal position. The nurse should remind the client to keep the legs apart at all times, and to use a pillow or a wedge between the legs when lying on the side.
