HESI CAT Exam Questions
Question 1 of 5
A client complains of paresthesia in the fingers and toes and experiences hand spasms when the blood pressure cuff is inflated. Which serum laboratory finding should the nurse expect to find when assessing the client?
Correct Answer: C
Rationale: The correct answer is C: Low serum calcium. Hand spasms and paresthesia are indicative of potential hypocalcemia, which is characterized by low serum calcium levels. Elevated serum calcium (Choice A) is not consistent with the symptoms described. Low serum magnesium (Choice B) and elevated serum potassium (Choice D) are not typically associated with hand spasms and paresthesia.
Question 2 of 5
The nurse is performing a peritoneal dialysis exchange on a client with chronic kidney disease (CKD). Which assessment finding should the nurse report to the healthcare provider?
Correct Answer: A
Rationale: Cloudy dialysate fluid can indicate peritonitis, a serious complication of peritoneal dialysis. Peritonitis is an urgent condition that requires immediate evaluation and treatment. Reporting this finding promptly is crucial to prevent further complications. Choices B, C, and D are not indicative of peritonitis and do not require immediate reporting to the healthcare provider. Complaining of slight shortness of breath, having a greater return volume, and experiencing abdominal fullness and cramping are common occurrences during peritoneal dialysis and do not necessarily indicate an emergent issue.
Question 3 of 5
A client admitted to the intensive care unit with syndrome of inappropriate antidiuretic hormone (SIADH) has developed osmotic demyelination. Which intervention should the nurse implement first?
Correct Answer: B
Rationale: Frequent reorientation is crucial for clients with neurological impairments from osmotic demyelination to prevent confusion and assist with orientation. It helps maintain a proper sense of time, place, and person, reducing disorientation. Patching one eye (Choice A) is not a priority intervention for osmotic demyelination and does not address the immediate need for reorientation. Range of motion exercises (Choice C) may be important for overall care, but reorientation takes precedence due to its impact on neurological functioning. Evaluating swallow (Choice D) is not the primary intervention needed for osmotic demyelination; it is essential but not the first priority.
Question 4 of 5
The healthcare provider prescribes a fluid challenge of 0.9% sodium chloride 1,000 ml to be infused over 4 hours. The IV administration set delivers 10gtt/ml. How many gtt/minute should the nurse regulate the infusion? (Enter a numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: A
Rationale: To calculate the rate: (1000 ml / 4 hours) = 250 ml/hour; (250 ml/hour) / (60 minutes/hour) = 4.17 ml/minute; (4.17 ml/minute) * (10 gtt/ml) = 41.7 gtt/minute, rounded to 42 gtt/minute. Therefore, the nurse should regulate the infusion at 42 gtt/minute to deliver the prescribed fluid challenge accurately. The other choices are incorrect as they do not reflect the correct calculation based on the given information.
Question 5 of 5
A mother brings her child, who has a history of asthma, to the emergency room. The child is wheezing and speaking one word between each breath. The child is anxious, tachycardic, and has labored respirations. Which assessment is most important for the nurse to obtain?
Correct Answer: C
Rationale: The correct answer is C because knowing the last dose and type of rescue inhaler used helps assess if the child has received adequate treatment and if further intervention is needed. This information is crucial in managing an acute asthma exacerbation. Choice A, the type of inhaler the child typically uses, is less critical during an emergency. Choice B, the frequency of rescue inhaler use during the week, is important for general asthma management but does not provide immediate guidance in the acute situation. Choice D, the type of allergen exposure or trigger, is more relevant for preventive strategies and does not directly impact the immediate treatment of the child's acute asthma attack.
