Adult Health Med Surg Nursing Test Banks

Correct Answer: B

Rationale: Normal saline is the preferred solution for wound irrigation because it is isotonic and will not damage healthy tissue or delay wound healing. It helps to remove debris and pathogens from the wound, promoting a clean environment for healing. Sterile water can be used if normal saline is not available, but it may cause cellular damage if used in large volumes. Hydrogen peroxide and Betadine solution are not recommended for wound irrigation as they can be cytotoxic to the tissues and interfere with the wound healing process. It's important for the nurse to use evidence-based practice and follow recommended guidelines to promote optimal wound healing outcomes.

Correct Answer: A

Rationale: The clinical presentation of gross hematuria, flank pain, palpable abdominal mass, along with imaging findings of a large heterogeneous renal mass with necrosis and calcifications are highly suggestive of renal cell carcinoma (RCC). RCC is the most common type of kidney cancer in adults. The presence of necrosis and calcifications are characteristic features of RCC. Imaging modalities such as CT scans or MRI can confirm the diagnosis by showing the typical features of RCC, including a solid mass with areas of necrosis and calcifications. It is important to further evaluate this patient, likely with a biopsy, to confirm the diagnosis and determine the extent of the disease for appropriate management.

Correct Answer: C

Rationale: The symptoms of polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) are classic signs of diabetes mellitus. In this case, the presence of hyperglycemia (high blood sugar) and glycosuria (glucose in the urine) further support the diagnosis of diabetes mellitus. Insulin deficiency or resistance in diabetes leads to impaired glucose utilization and excessive glucose in the bloodstream, causing the classic symptoms observed in the patient. Hyperthyroidism, hypothyroidism, and Cushing's syndrome do not typically present with the hallmark symptoms of polyuria, polydipsia, and polyphagia associated with uncontrolled diabetes mellitus.

Correct Answer: C

Rationale: Ethnographic research allows researchers to be neutral observers because it involves immersing oneself in the culture or community being studied without imposing their own biases or preconceptions. Ethnographers aim to understand the perspectives and behaviors of the people they are studying by observing them in their natural environment and engaging in participant observation. This approach enables researchers to gain insights into the social and cultural context of their subjects without influencing the outcomes or reactions. By maintaining neutrality and objectivity, ethnographic researchers can produce more authentic and unbiased results.

Correct Answer: C

Rationale: Naloxone, also known by the brand name Narcan, is used to reverse the effects of opioid overdose. Opioids can cause respiratory depression, sedation, and other signs of toxicity. Administering naloxone can quickly reverse these effects, restoring the patient's breathing and consciousness. This makes it the appropriate choice for reversing all signs of toxicity related to opioids. Digibind (Digoxin) is used to reverse toxicity from digoxin specifically. Atropine sulfate is used for bradycardia. Diazepam (Valium) is a benzodiazepine used for anxiety, seizures, and muscle relaxation, not for reversing toxicity.
