Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. This is the most important nursing intervention for a client with severe dehydration because IV fluids provide rapid rehydration and help restore electrolyte balance efficiently. Monitoring vital signs (choice B) is important but not as crucial as providing immediate fluid replacement. Providing oral rehydration (choice C) may not be effective for severe dehydration as the client may have difficulty absorbing fluids orally. Administering oxygen (choice D) is not directly related to treating dehydration, so it is not the most important intervention in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Kidney function tests. In diabetic nephropathy, the kidneys are affected, leading to impaired kidney function. Monitoring kidney function tests such as serum creatinine and glomerular filtration rate is crucial to assess the progression of the disease and guide treatment. Blood pressure measurement (B) is important in managing diabetic nephropathy but does not directly assess kidney function. Blood glucose levels (C) are essential in managing diabetes overall but do not specifically address nephropathy. Urine output monitoring (D) is important for assessing kidney function but does not provide as comprehensive information as kidney function tests.

Correct Answer: B

Rationale: The correct answer is B: "I can wear tight shoes to avoid blisters." Tight shoes can increase pressure on the feet, leading to blisters and worsening neuropathy symptoms. A: Inspecting feet daily is important to catch any issues early. C: Walking barefoot can increase the risk of injuries. D: Maintaining blood glucose levels within target range is crucial for managing diabetic neuropathy. In summary, the incorrect choices either provide important preventive measures or focus on key aspects of diabetes management, while the correct choice suggests a harmful behavior that can exacerbate neuropathy symptoms.

Correct Answer: D

Rationale: The correct answer is D: Huntington's chorea. Huntington's chorea is a genetic disorder characterized by involuntary, writhing, and twisting movements of the face and limbs, known as chorea. This is due to degeneration of certain brain cells. Epilepsy (A) involves seizures, not specific movements. Parkinson's (B) is characterized by tremors and rigidity, not chorea. Multiple sclerosis (C) affects the central nervous system, causing a variety of symptoms, but not typically chorea.

Correct Answer: C

Rationale: The correct answer is C: Ashen, grey, or dull. In patients of African descent, skin characteristics may appear ashen, grey, or dull when experiencing shock due to reduced blood flow and oxygen delivery. This is because the skin may appear pale or lacking in color due to decreased perfusion. The other choices are incorrect because: A: Ruddy blue - Ruddy blue skin color is not typically associated with shock in patients of African descent. B: Generalized pallor - Generalized pallor refers to an overall paleness of the skin, which is not commonly seen in patients of African descent during shock. D: Patchy areas of pallor - Patchy areas of pallor suggest uneven skin color changes, which are not typically characteristic of shock in patients of African descent.
