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: C

Rationale: The correct answer is C. In hypothyroidism, the thyroid gland is underactive, leading to symptoms like puffiness of the face and hands due to fluid retention. This occurs as a result of decreased metabolism. Options A and B are symptoms of hyperthyroidism, where the thyroid gland is overactive. Option D is a symptom of goiter, which is thyroid gland swelling, not specific to hypothyroidism. Therefore, the correct answer is C based on the characteristic symptoms of hypothyroidism.

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: General to specific assessment. In this scenario, the nurse is starting with a broad assessment of the surgical dressing and the type of drainage present, then will progress to more specific assessments based on the findings. This approach allows for a systematic and comprehensive evaluation of the patient's condition by moving from general observations to detailed examinations. Explanation: 1. General assessment: The nurse is initially assessing the overall appearance of the surgical dressing and the type of drainage. 2. Specific assessment: Based on the initial findings, the nurse will proceed to conduct more focused assessments, such as checking for signs of infection, monitoring vital signs, and assessing the surgical site for any complications. Other choices are incorrect: A: Gordon’s Functional Health Patterns - This framework focuses on assessing different aspects of an individual's health patterns, such as activity level, sleep patterns, and coping mechanisms. It is not the most appropriate approach in this situation. B: Activity-exercise pattern assessment - This type of assessment focuses

Correct Answer: B

Rationale: The correct answer is B: To prevent cerebrospinal fluid (CSF) leakage. Rationale: During a spinal block, the anesthesiologist injects anesthesia into the subarachnoid space, which contains CSF. Proper positioning ensures that the anesthesia stays in place and prevents leakage of CSF, which could lead to complications such as post-dural puncture headache. Incorrect choices: A: To prevent confusion - Irrelevant to the procedure. C: To prevent seizures leakage - Seizures are not a concern with spinal blocks. D: To prevent cardiac arrhythmias - Cardiac arrhythmias are not directly related to spinal blocks.
