Medical Surgical HESI 2023

Correct Answer: B

Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.

Correct Answer: D

Rationale: Administering an antipyretic is the most important intervention. The client presents with an elevated temperature, tachycardia, and tachypnea, indicating a fever. Lowering the temperature with an antipyretic is crucial to prevent complications like dehydration, altered mental status, and increased oxygen demand. While assessing lower extremity circulation and oxygen saturation are important, addressing the elevated temperature takes priority in this scenario. Incentive spirometry may be beneficial but is not the priority compared to managing the fever.

Correct Answer: B

Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). This test is used to monitor the effectiveness of heparin therapy. A complete blood count (CBC) (choice A) is not specific for monitoring heparin therapy. Prothrombin time (PT) (choice C) and International normalized ratio (INR) (choice D) are more commonly used to monitor warfarin therapy, not heparin.

Correct Answer: A

Rationale: The correct answer is A. Gout is characterized by the deposition of uric acid crystals in the synovial fluid of joints, which triggers inflammation and pain. This process is known as crystal-induced arthritis. Choice B is incorrect as gout does not involve degeneration of joint cartilage. Choice C is incorrect as gout is not caused by an infection of the joint space. Choice D is incorrect as gout does not result from increased synovial fluid but rather from the deposition of uric acid crystals.

Correct Answer: C

Rationale: The correct answer is C: Hemoglobin and hematocrit. Epoetin alfa is a medication that stimulates red blood cell production, so monitoring hemoglobin and hematocrit levels is essential to assess its effectiveness. These values reflect the oxygen-carrying capacity of the blood and can indicate if the treatment is improving anemia related to chronic kidney disease. Choices A, B, and D are incorrect. Blood urea nitrogen (BUN) and serum creatinine are indicators of kidney function, while serum potassium levels are monitored due to electrolyte imbalances commonly seen in kidney disease, but they do not directly reflect the effectiveness of epoetin alfa.
