PN ATI Comprehensive Predictor

Correct Answer: D

Rationale: Administering analgesics on a scheduled basis for the first 24 hours is crucial to ensure adequate pain control in the immediate postoperative period. Choice A is incorrect because clear liquids are typically initiated gradually and advanced as tolerated but not specifically at 6 hours post-surgery. Choice B is incorrect as cromolyn nebulizer solution is not indicated for postoperative pain management in this scenario. Choice C is incorrect as applying a warm compress may not be appropriate for the operative site after appendicitis surgery and can potentially increase the risk of infection.

Correct Answer: B

Rationale: The correct answer is B: 'As soon as the client awakens in the morning.' Sputum specimens should be collected early in the morning to obtain a concentrated sample. This timing ensures that the specimen is less diluted, providing a more accurate analysis. Choices A, C, and D are incorrect as they do not align with the optimal timing for collecting a sputum specimen, which is in the morning.

Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

Correct Answer: C

Rationale: The correct answer is to monitor the client's fluid and electrolyte levels. When caring for a client with dehydration, it is crucial to assess and monitor their fluid and electrolyte status to guide appropriate interventions. Administering antiemetics may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink oral rehydration solutions is beneficial but may not be the immediate priority if the client is severely dehydrated. Administering intravenous fluids may be necessary based on the assessment of fluid and electrolyte levels, making monitoring these levels the priority intervention.

Correct Answer: C

Rationale: Choice C is the correct answer. During a colonoscopy, clients are typically sedated, so they do not feel any pain during the procedure. Choices A, B, and D are incorrect. Clients are usually required to stop eating and drinking at least 24 hours before a colonoscopy, and there are specific dietary restrictions that need to be followed before the procedure to ensure a successful examination.
