Correct Answer: B

Rationale: In schizophrenia, clients often display an inability to identify common objects due to cognitive impairment. This is known as associative agnosia, where individuals struggle to recognize familiar objects, faces, or sounds. Choices A, C, and D are not typically associated with schizophrenia. Decreased level of consciousness is more indicative of conditions like head trauma or drug overdose. Poor problem-solving ability may be seen in various mental health disorders but is not specific to schizophrenia. Preoccupation with somatic disturbances is more commonly seen in somatic symptom disorders or somatic delusions, not a typical finding in schizophrenia.

Correct Answer: A

Rationale: Administering oxygen is the most appropriate intervention for a patient with confusion post-surgery because it helps alleviate confusion caused by potential hypoxia. In a post-surgical setting, confusion can be a sign of decreased oxygen levels in the blood due to various reasons such as respiratory depression, decreased lung function, or other complications. Administering oxygen can quickly address hypoxia, improving oxygenation to the brain and reducing confusion. Repositioning the patient, administering IV fluids, or performing a neurological assessment are not the primary interventions for confusion related to hypoxia post-surgery.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions as it helps reverse the symptoms rapidly by constricting blood vessels, increasing heart rate, and opening airways. Antihistamines (Choice B) may help with mild allergic reactions but are not effective for severe cases. Corticosteroids (Choice C) are used to reduce inflammation and are typically not the first-line treatment for acute severe allergic reactions. Administering oxygen (Choice D) may be necessary to support breathing in severe cases, but epinephrine is the primary treatment to reverse the allergic reaction symptoms.

Correct Answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

Correct Answer: C

Rationale: The correct action for a nurse caring for a client with deep vein thrombosis (DVT) is to apply warm compresses to the affected extremity. Warm compresses help reduce swelling and pain in clients with DVT. Administering thrombolytics (Choice A) is not typically done without specific orders due to the risk of bleeding. Massaging the affected extremity (Choice B) can dislodge blood clots and lead to complications. Placing the client in a supine position with the legs elevated (Choice D) may increase the risk of clot dislodgment.
