Practice HESI Fundamentals Exam

Correct Answer: D

Rationale: As death approaches, decreased muscle tone and other signs like decreased blood pressure, irregular breathing patterns, cold extremities, and decreased urine output are common. Warm extremities (choice B) would not be expected as circulation may be compromised. Increased urine output (choice C) is unlikely as organ function declines. A regular breathing pattern (choice A) is also unlikely as irregular breathing patterns are common near death.

Correct Answer: C

Rationale: The correct answer is C. Clothes becoming tighter across the abdomen is indicative of an abdominal mass, a common presentation in neuroblastoma. This symptom should be followed up on further as it aligns with the diagnosis. Choices A, B, and D are less specific to neuroblastoma. Weight loss and listlessness (Choice A) can be nonspecific symptoms, while dark yellow urine in small amounts (Choice B) may suggest dehydration or other conditions. Muscle weakness and unsteadiness (Choice D) could point towards various neurological or muscular issues but are not as directly related to neuroblastoma as the symptom described in Choice C.

Correct Answer: B

Rationale: The correct answer is B: Renal stones. Renal calculi are calcium stones that can form in the renal pelvis or pass through the ureters. Immobilized patients, who have hypercalcemia, are at increased risk for developing renal stones. Monitoring for signs and symptoms of renal stones is crucial in this patient population. Choices A, C, and D are incorrect because although they are potential complications in immobilized patients, they are not directly associated with hypercalcemia and do not match the scenario described in the question.

Correct Answer: A

Rationale: The correct answer is A: Absence of a pulse. Prior to initiating chest compressions during CPR, it is essential to confirm the absence of a pulse. Chest compressions are indicated when there is no detectable pulse as it signifies cardiac arrest. Checking for a pulse is a critical step to ensure that CPR is performed on individuals who truly require it. Choices B, C, and D are incorrect because focusing on the presence of a pulse, respiratory rate, or blood pressure before starting chest compressions can delay life-saving interventions in a person experiencing cardiac arrest.

Correct Answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.
