HESI RN Exit Exam

Correct Answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

Correct Answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

Correct Answer: A

Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant in assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Excessive sleepiness and difficulty feeding can be signs of hypothyroidism in infants. Asking about the infant's sleepiness and feeding pattern is crucial in assessing for hypothyroidism. Choice A is incorrect because immunizations are not directly related to hypothyroidism. Choice C is about feeding method and not specific to hypothyroidism. Choice D is unrelated as it asks about relatives with birth defects, which does not directly assess the infant's condition.

Correct Answer: A

Rationale: In a 60-year-old female client with a family history of ovarian cancer and an abdominal mass, further evaluation involving surgery may be needed to rule out ovarian cancer. The presence of an abdominal mass raises suspicion for a possible malignancy, and a negative Pap smear result does not rule out ovarian cancer. A pelvic exam alone may not provide sufficient information to confirm or rule out ovarian cancer. Continuing Pap smear evaluations every six months or waiting for one additional negative Pap smear in six months is not appropriate in this scenario, as the abdominal mass requires immediate attention and further evaluation.
