HESI Exit Exam RN Capstone

Correct Answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

Correct Answer: D

Rationale: The correct answer is D. Assessing skin turgor is crucial as tented skin turgor indicates dehydration, which can be worsened by antidiarrheal medications like diphenoxylate. Providing fluids is essential to address dehydration in this client. Monitoring fluid intake (choice A) is important, but assessing skin turgor takes precedence in this situation. Obtaining a stool sample for testing (choice B) could be necessary for diagnostic purposes but is not the immediate priority. Administering a laxative (choice C) is contraindicated in this case as it can worsen the client's condition by further exacerbating fluid loss.

Correct Answer: C

Rationale: A pulse oximetry reading of 88 indicates hypoxia, which is a serious condition requiring immediate intervention. Adequate oxygenation is crucial for the client's well-being. Choices A and B are normal findings after endotracheal intubation. Hearing bilateral breath sounds and seeing mist in the T-piece indicate proper functioning of the endotracheal tube. While choice D may indicate an issue with speaking due to the endotracheal tube, it is not as critical as the hypoxia indicated by the low pulse oximetry reading.

Correct Answer: D

Rationale: The correct answer is to increase the humidity of the oxygen source. This action helps thin thick secretions, making them easier to clear from the tracheostomy tube. Increasing fluid intake (Choice A) can be beneficial in some cases but addressing humidity is more specific to managing thick secretions in a client with a tracheostomy. Tracheal suctioning (Choice B) should be done after attempting to thin the secretions with increased humidity. Administering a mucolytic agent (Choice C) is a possible intervention but typically comes after addressing humidity and before resorting to suctioning to avoid unnecessary invasiveness.

Correct Answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.
