HESI RN Exit Exam 2024 Capstone

Correct Answer: C

Rationale: The correct answer is C: Applying oxygen therapy at a high flow rate. In clients with COPD, high levels of supplemental oxygen can suppress the hypoxic drive to breathe, leading to carbon dioxide retention and respiratory depression. Oxygen therapy must be administered cautiously to prevent worsening respiratory status. Administering narcotics for pain relief (Choice A) can be necessary but should be done judiciously. Encouraging fluid intake (Choice B) and assisting with deep breathing exercises (Choice D) are generally beneficial interventions for clients with COPD and should not require the same level of caution as high-flow oxygen therapy.

Correct Answer: B

Rationale: The correct answer is B. Using nitroglycerin as needed, every 5 minutes, up to 3 doses, is the appropriate management for angina at rest. This helps dilate blood vessels, improving blood flow to the heart. Choice A is incorrect because chest pain that persists at rest should be addressed immediately, not waiting for 30 minutes. Choice C is incorrect as avoiding physical activity is not a recommended approach during an angina episode. Choice D is incorrect because nitroglycerin should be used during chest pain episodes, not as a preventive measure before physical activity.

Correct Answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.

Correct Answer: B

Rationale: In this scenario, the nurse should first start an intravenous fluid bolus. This intervention is crucial in addressing severe dehydration associated with diabetic ketoacidosis, a life-threatening complication of type 1 diabetes. Administering intravenous insulin (Choice A) is important but should follow fluid resuscitation. Obtaining a blood glucose level (Choice C) is necessary but not as urgent as addressing the dehydration. Administering an antiemetic (Choice D) is not the priority in this situation.

Correct Answer: B

Rationale: Verifying the correct placement of a nasogastric tube before each feeding is essential to prevent aspiration and ensure that the tube is properly positioned in the stomach or intestine. This action is a priority to maintain client safety. Flushing the tube with water every 4 hours is important for tube patency but is not the priority over verifying placement. Securing the tube with tape and keeping the head of the bed elevated are crucial but are considered secondary measures compared to confirming the correct tube placement.
