A nurse is teaching an in-service about cancer at a staff meeting. Which of the following information should the nurse include about adenocarcinoma?

"Pancreatic cancer doesn't usually present as an adenocarcinoma."

"Colorectal adenocarcinomas tend to have high treatment response rates."

"Many brain tumors are adenocarcinomas."

"Most prostate cancers are slow-growing adenocarcinomas."

Answer and Explanation

The Correct Answer is D

A. "Pancreatic cancer doesn't usually present as an adenocarcinoma.": Pancreatic cancer most commonly arises from the exocrine glands and is typically classified as an adenocarcinoma. It is the most frequent histological type found in pancreatic malignancies.
B. "Colorectal adenocarcinomas tend to have high treatment response rates.": Treatment response in colorectal adenocarcinoma depends heavily on the stage at diagnosis. While early-stage tumors may respond well, advanced stages often have lower responsiveness and poorer outcomes.
C. "Many brain tumors are adenocarcinomas.": Primary brain tumors are typically glial in origin, such as astrocytomas or glioblastomas. Adenocarcinomas rarely originate in the brain and are more often found in epithelial tissues like the lungs, colon, or prostate.
D. "Most prostate cancers are slow-growing adenocarcinomas.": Prostate cancer most often originates from glandular tissue and is classified as an adenocarcinoma. These tumors commonly progress slowly, especially in older adults, and may be monitored for years without requiring aggressive treatment.

Correct Answer is A

Explanation

A. U waves on electrocardiogram: Hypokalemia affects cardiac conduction and is typically reflected on an ECG by the presence of prominent U waves. These appear after the T wave and are considered a classic finding in hypokalemia.
B. Hyperventilation: Hyperventilation is more commonly associated with respiratory alkalosis or anxiety, not directly with hypokalemia. In fact, hypokalemia can cause muscle weakness that might lead to hypoventilation rather than hyperventilation.
C. Syncope: Although severe electrolyte imbalances can contribute to syncope, it is not a specific or reliable early indicator of hypokalemia. Cardiac arrhythmias are more directly associated with low potassium.
D. Bradypnea: Bradypnea is not a common manifestation of hypokalemia. Respiratory muscle weakness from severe hypokalemia may cause shallow breathing, but not specifically a slow respiratory rate.

A. Reports pain as 5 on a scale of 0 to 10 B. Been on bedrest for 3 days C. Last bowel movement 2 days ago D. Consumed 35% of meals for 12 hr

Correct Answer is B

Explanation

A. "Reports pain as 5 on a scale of 0 to 10": While pain is an important concern, it is not the most immediate issue in this case. The nurse should first assess for factors that could contribute to complications or more severe issues.
B. "Been on bedrest for 3 days": Prolonged bedrest increases the risk of complications such as deep vein thrombosis (DVT), pulmonary embolism, or muscle atrophy. This is the priority because the client may be at risk for serious complications due to immobility.
C. "Last bowel movement 2 days ago": While constipation can cause discomfort, it is not as urgent as the risk posed by prolonged bedrest. This issue can be addressed once other more serious complications have been ruled out.
D. "Consumed 35% of meals for 12 hr": Poor nutrition is important to monitor, but it is not the immediate concern in this case. The focus should be on potential complications related to immobility, such as clot formation or respiratory issues.
