The school nurse is preparing a presentation on the importance of physical activity for elementary school students. Which benefit should the nurse emphasize?

Correct Answer: A

Rationale: The correct answer is A: Improved academic performance. Physical activity has been shown to improve academic performance by enhancing concentration and cognitive function. This benefit is particularly important for elementary school students who are developing foundational skills. Choice B, increased social interactions, while important for overall development, may not directly relate to the academic aspect that the nurse is focusing on. Choice C, enhanced physical strength, is a valid benefit of physical activity but may not be as relevant to academic performance as the ability to concentrate and learn. Choice D, better sleep patterns, is also a valuable outcome of physical activity but is not as directly linked to academic performance as improved cognitive function.

Correct Answer: C

Rationale: A temperature of 102°F (38.9°C) is the most important assessment finding to report to the healthcare provider in a client with pancreatitis and a history of alcoholism. Fever in this context can indicate infection, which is a serious complication requiring immediate intervention. Nausea and vomiting (choice A) are common symptoms of pancreatitis but may not require immediate intervention unless severe. Epigastric pain radiating to the back (choice B) is a classic symptom of pancreatitis and should be addressed, but a fever takes precedence. Mild jaundice (choice D) may be present in pancreatitis but is not as urgent as a high temperature signaling possible infection.

Correct Answer: C

Rationale: In a client with a head injury, being drowsy but still arousable can be a sign of increased intracranial pressure, which necessitates immediate intervention. This presentation may indicate a deterioration in neurological status, requiring prompt assessment and management to prevent further complications. Choices A, B, and D are not indicative of an immediate need for intervention in this scenario. A Glasgow Coma Scale (GCS) score of 15 indicates the highest level of consciousness; pupils being equal and reactive to light suggest intact cranial nerve function, and memory loss about the injury event is common in head injuries and does not necessarily warrant immediate intervention.

Correct Answer: D

Rationale: The correct answer is D because participating in contact sports can increase the risk of injury and bleeding in a client receiving warfarin therapy. Warfarin is a blood thinner, and activities with a higher risk of injury should be avoided to prevent bleeding complications. Choices A, B, and C are all correct statements for a client on warfarin therapy. Avoiding foods high in vitamin K helps maintain consistent anticoagulation levels, using a soft toothbrush and an electric razor reduces the risk of bleeding gums and cuts, and keeping appointments for blood tests ensures proper monitoring of the client's international normalized ratio (INR) levels.

Correct Answer: B

Rationale: The correct answer is B: Furosemide (Lasix). Furosemide is a diuretic that promotes fluid loss, and giving it before hemodialysis can lead to excessive fluid loss during the treatment, potentially causing hypovolemia. Withholding furosemide until after the dialysis session helps in preventing this complication. Choices A, C, and D are incorrect because calcium carbonate, spironolactone, and multivitamins are not typically contraindicated before hemodialysis in clients with chronic renal failure.
