Which of the ff is the primary sign of breast cancer?

Correct Answer: D

Rationale: The correct answer is D: A painless mass in the breast. This is the primary sign of breast cancer because most breast cancers present as painless lumps or masses. This is due to the abnormal growth of cells forming a tumor. Other choices (A, B, C) are also signs of breast cancer, but they are not as common or primary as the presence of a painless mass. A bloody discharge from the nipple (A) can be a sign of a benign condition or cancer, but it is not the most common presentation. Nipple retraction (B) and dimpling of the skin over the lesion (C) can also be signs of breast cancer, but they usually occur in later stages of the disease. Therefore, the presence of a painless mass in the breast is the primary sign that should raise suspicion for breast cancer.

Correct Answer: C

Rationale: The correct answer is C: Muscle weakness. Metolazone is a diuretic that can lead to low potassium levels, causing muscle weakness. Instructing the patient to report muscle weakness is crucial to prevent any potential serious complications. Numb hands, gastrointestinal distress, and nightmares are not commonly associated with metolazone and do not pose as immediate risks as muscle weakness does. It is essential to prioritize the most critical side effect to ensure the patient's safety and well-being.

Correct Answer: B

Rationale: The correct answer is B. A semiprivate room with one or two consistent caregivers is the most therapeutic setting for an agitated head-injured patient. Here's the rationale: 1. Consistency: Having one or two consistent caregivers provides the patient with a stable and familiar environment, which can help reduce agitation. 2. Privacy: A semiprivate room offers more privacy compared to a day room or a ward, which can help minimize external stimuli and promote relaxation. 3. Individualized care: In a semiprivate room, caregivers can focus more on the specific needs of the patient, leading to better management of agitation. 4. Reduced distractions: Being in a semiprivate room minimizes distractions and noise, which can be overwhelming for an agitated head-injured patient. Summary: A, C, and D are incorrect because they do not offer the same level of consistency, privacy, individualized care, and reduced distractions as a semiprivate room with one

Correct Answer: C

Rationale: The correct answer is C: High fluid intake. Adequate hydration helps prevent calcium from becoming concentrated in the urine, reducing the risk of calcium stone formation. Increased fiber intake (choice A) may help prevent other types of stones but not specifically calcium stones. Increased protein intake (choice B) can actually increase calcium excretion, potentially increasing the risk of calcium stone formation. Zinc intake (choice D) does not directly impact calcium stone formation. In summary, high fluid intake is crucial for preventing the precipitation of calcium renal stones due to its role in diluting urine and preventing calcium concentration.

Correct Answer: D

Rationale: The correct answer is D: The client is experiencing a mild overdosage. Tinnitus is a common symptom of aspirin toxicity. Aspirin overdose can lead to tinnitus due to its ototoxic effects. This occurrence indicates that the client may be taking too much aspirin, resulting in toxicity. The other choices (A, B, C) are incorrect because tinnitus is not a normal side effect of aspirin working correctly, upper GI bleed, or a metallic taste in the mouth.
