Correct Answer: B

Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.

Correct Answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

Correct Answer: D

Rationale: Elevated temperature is the correct finding to report immediately in a client with a history of peptic ulcer disease and abdominal pain. This could indicate a perforation or worsening of the condition, requiring prompt medical attention. Positive bowel sounds (Choice A) are a normal finding and not a cause for concern. Rebound tenderness (Choice B) is concerning but does not require immediate attention compared to an elevated temperature. Increased appetite (Choice C) is not a red flag symptom for peptic ulcer disease and can be considered a positive sign, not requiring immediate attention.

Correct Answer: A

Rationale: The correct technique for eliciting the client's patellar reflex is to tap just below the knee. This action stimulates the stretch receptors in the patellar tendon, leading to a reflex contraction of the quadriceps muscle and extension of the lower leg. Tapping on the upper thigh (Choice B) would not elicit the patellar reflex as it targets a different area. Similarly, tapping on the ankle (Choice C) or tapping on the lower leg (Choice D) would not produce the desired response associated with the patellar reflex, making them incorrect choices.

Correct Answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the drug's metabolism in the liver. Monitoring liver enzymes such as AST and ALT is crucial as they indicate liver function and damage. Prothrombin time (PT) and partial thromboplastin time (PTT) (Choice A) are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts (Choice B) are not directly related to acetaminophen poisoning. Blood urea nitrogen and creatinine levels (Choice C) assess kidney function, but liver enzymes are more specific for evaluating liver damage in acetaminophen poisoning.
