A 52-year old female tells the nurse that she has found a painless lump in her right breast during her monthly self- examination. Which assessment finding would strongly suggest that this client's lump is cancerous?

Correct Answer: C

Rationale: The assessment finding that strongly suggests that the client's lump is cancerous is a non-mobile mass with irregular edges delineated. Generally, cancerous breast lumps tend to have irregular shapes/edges and lack mobility. This finding is concerning for malignancy because it indicates that the lump is fixed in place and possibly invading nearby tissues, which are characteristics often associated with cancerous tumors. It's essential for the client to undergo further diagnostic tests, such as a biopsy, to confirm the presence of cancer and establish a proper treatment plan.

Correct Answer: B

Rationale: A fixed nodular mass with dimpling of the overlying skin is the finding that most strongly suggests breast cancer. This presentation is concerning for an invasive carcinoma that has invaded into the surrounding tissues, leading to the dimpling of the skin. Breast cancer typically presents as a painless, hard, irregularly shaped, non-mobile mass. Dimpling of the skin overlying the mass is a sign of advanced disease and is often associated with a poor prognosis. Therefore, this finding should raise suspicion for breast cancer and prompt further evaluation and workup.

Correct Answer: D

Rationale: In newborns, intramuscular phytonadione (vitamin K) is typically administered into the vastus lateralis muscle. This muscle is located on the front of the thigh and is a commonly used site for IM injections in infants due to its large muscle mass, accessibility, and low risk of hitting major nerves or blood vessels. The vastus lateralis muscle is considered a safe and effective site for administering medications to newborns.

Correct Answer: C

Rationale: The best response by the nurse is to explain that someone will assist the patient as long as she is in the rehabilitation facility. This is important for ensuring the safety of the patient, especially considering her condition with left-sided hemiparesis resulting from a subarachnoid hemorrhage. While encouraging independence is important in rehabilitation, it should not compromise the patient's safety. The nurse should prioritize the patient's well-being and provide necessary assistance to prevent any potential falls or injuries during ambulation.aising the risk of falling or getting injured.

Correct Answer: A
