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: B

Rationale: The client should be advised to avoid foods rich in milk and cream. Although they provide temporary relief, dairy products, especially milk, stimulate gastric acid secretion, which can exacerbate the symptoms of a duodenal ulcer. Encouraging the client to drink milk (Choice A) would be counterproductive and could worsen the condition. Instructing the client to take antacids (Choice C) may provide symptomatic relief but does not address the root cause of the issue. Advising the client to monitor their symptoms (Choice D) is vague and does not provide specific guidance on managing the duodenal ulcer. Therefore, the best action is to review with the client the need to avoid foods rich in milk and cream to ensure proper ulcer management.

Correct Answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.

Correct Answer: D

Rationale: A decrease in respiratory rate indicates that the client's breathing is becoming more stable, which suggests an improvement in their condition. Respiratory rate is a critical indicator of respiratory status and oxygenation. Increased white blood cell count (choice A) suggests ongoing infection, crackles on lung auscultation (choice B) indicate fluid in the lungs, and productive cough with green sputum (choice C) may indicate persistent infection or airway inflammation, which do not necessarily reflect improvement in pneumonia.

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.
