- A. 120/70 mmHg
- B. 135/85 mmHg
- C. 130/80 mmHg
- D. 125/75 mmHg
Correct Answer: A
Rationale: Home night BP 120/70 fits normal, not 130+ creepers. Nurses clock this chronic sleep dip.

The most common and significant symptom associated with cancer and associated treatments, which has a long term impact on quality of life, as reported by patients, is:
- A. Anorexia
- B. Alopecia
- C. Pain
- D. Fatigue
Correct Answer: D
Rationale: Cancer's top drag fatigue saps QOL long-term, outlasting appetite, hair, or pain woes. Nurses hear this, a chronic weary king.
A 54-year-old has a diagnosis of breast cancer and is tearfully discussing her diagnosis with the nurse. The patient states, 'They tell me my cancer is malignant, while my coworker's breast tumor was benign. I just don't understand at all.' When preparing a response to this patient, the nurse should be cognizant of what characteristic that distinguishes malignant cells from benign cells of the same tissue type?
- A. Slow rate of mitosis of cancer cells
- B. Different proteins in the cell membrane
- C. Differing size of the cells
- D. Different molecular structure in the cells
Correct Answer: B
Rationale: Malignant breast cancer cells flaunt tumor-specific antigens (e.g., CEA) on their membranes, unlike benign ones from the same tissue think of it as a wanted' sign for the immune system. Mitosis isn't slow it's fast in malignant cells. Size varies, not the defining split. Molecular structure shifts, but membrane proteins are the standout marker. Nurses use this to explain why her cancer's a threat those antigens tag it as invasive, a core oncology lesson for scared patients piecing it together.
You are caring for a patient with esophageal cancer. Which task could be delegated to the nursing assistant?
- A. Assist the patient with oral hygiene
- B. Observe the patient's response to feedings
- C. Facilitate expression of grief or anxiety
- D. Initiate daily weights
Correct Answer: A
Rationale: Delegating tasks in nursing hinges on scope of practice. Assisting with oral hygiene is a basic care activity nursing assistants are trained to perform, supporting hygiene needs in esophageal cancer patients who may struggle with swallowing. Observing responses to feedings requires clinical judgment to assess tolerance or complications, a nurse's responsibility. Facilitating emotional expression involves therapeutic communication skills beyond an assistant's training, critical for addressing cancer-related distress. Initiating daily weights implies deciding when to start, requiring understanding of fluid status assistants can weigh patients but not initiate the process independently. Oral hygiene delegation optimizes care efficiency, aligns with assistants' capabilities, and frees nurses for higher-level assessments, ensuring safe, effective management of this patient's complex needs.
A 50-year-old patient, body weight 98 kg and height 1.82 m, has been diagnosed with type 2 diabetes based on increased fasting blood glucose levels (8.2 and 7.9 mmol/L). This gave the patient such a shock that he started a strict calorie-restricted diet. Two weeks later, his fasting blood glucose is 6.8 mmol/L and he has lost 1 kg. Question: What is the most likely explanation for the sharp reduction of the blood glucose level and the limited reduction in weight of only ±1%?
- A. The insulin-stimulated glucose uptake in muscle tissue has increased
- B. The insulin-stimulated inhibition of hepatic glucose production has increased
- C. The insulin-stimulated uptake of free fatty acids in muscle tissue has increased
- D. The insulin-stimulated inhibition of glycerol production in the liver has increased
Correct Answer: B
Rationale: Type 2's glucose drop calorie cut reins in liver's sugar spill, insulin works better there. Muscle uptake helps, fat shifts less, glycerol's minor liver's the quick fix, weight lags nurses see this, a chronic tweak.
There are several mechanisms through which AGEs can lead to increased oxidative stress. Question: Which AGE-induced mechanism supposedly plays an important role in the development of oxidative stress in endothelial cells?
- A. Crosslinking of matrix proteins
- B. Induction of apoptosis
- C. Intracellular glycation by methylglyoxal
- D. All three statements provided above are correct
Correct Answer: C
Rationale: AGEs spark stress methylglyoxal's indoor glycation fries cells, outpacing crosslinking or death calls. Key in endothelium, a chronic oxidative kick nurses target this mess.
