Correct Answer: D

Rationale: The correct answer is D. Decreased frequency of ventricular tachycardia (VT) episodes indicates that the lidocaine infusion is effectively managing the ventricular tachycardia. Stabilization of BP ranges (choice A) may not directly correlate with the therapeutic response to lidocaine for VT. Cessation of chest pain (choice B) may indicate pain relief but does not specifically address the effectiveness of lidocaine for VT. Reduced heart rate (choice C) is not a direct indicator of the response to lidocaine for managing VT.

Correct Answer: C

Rationale: The correct answer is C: Fever, irritability, pulling on the ear. Clinical manifestations of otitis media commonly include fever, irritability, and children may show signs of pulling or rubbing their ears. Choices A, B, and D are incorrect. Choice A includes wheezing and vomiting, which are not typical symptoms of otitis media. Choice B includes coughing, rhinorrhea, and headache, which are more commonly associated with upper respiratory infections rather than otitis media. Choice D includes wheezing, cough, and drainage in the ear canal, which are not typical clinical manifestations of otitis media.

Correct Answer: B

Rationale: Administering intravenous antibiotics is the priority when caring for a client with suspected meningitis. The prompt administration of antibiotics is crucial to treat bacterial meningitis and prevent potential complications. Isolating the client in a private room may be necessary to prevent the spread of infection, but antibiotic administration takes precedence. Obtaining a throat culture and performing a chest x-ray are important diagnostic measures, but they do not address the immediate need for antibiotic therapy in suspected bacterial meningitis.

Correct Answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.

Correct Answer: D

Rationale: After rehydration, it is important to offer foods that are nonirritating to the bowel to the child. Bananas and rice are considered the best options as they are least likely to irritate the gastrointestinal tract. Apricots, peaches, and applesauce are fruits that may cause GI irritation, while milk, including chocolate milk, can also be irritating to the bowel. Therefore, the optimal choice for a child recovering from diarrhea would be bananas and rice.
