HESI Fundamentals Study Guide Questions
Question 1 of 5
A healthcare professional is reviewing a client's fluid and electrolyte status. Which of the following findings should the healthcare professional report to the provider?
Correct Answer: D
Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.
Question 2 of 5
A client has recently started using a behind-the-ear hearing aid. Which of the following statements should the nurse identify as an indication that the client understands the use of this assistive device?
Correct Answer: D
Rationale: The correct answer is D because removing the hearing aid before taking a shower is essential to prevent water damage, as moisture can harm the device. Choice A is incorrect because behind-the-ear hearing aids do allow for fine-tuning of volume. Choice B is incorrect because exercise may cause the hearing aid to shift position, so it's important to ensure it stays secure. Choice C is incorrect because hearing a whistling sound when inserting the hearing aid may indicate improper placement or fit.
Question 3 of 5
A healthcare professional is preparing to assess a patient for orthostatic hypotension. Which piece of equipment will the professional obtain to assess for this condition?
Correct Answer: C
Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.
Question 4 of 5
The healthcare provider is assessing an immobile patient for deep vein thromboses (DVTs). Which action will the healthcare provider take?
Correct Answer: B
Rationale: The correct action when assessing an immobile patient for deep vein thromboses (DVTs) is to measure the calf circumference of both legs. This helps in detecting swelling or changes that may indicate the presence of a DVT. Removing elastic stockings every 4 hours (Choice A) is not necessary and can disrupt circulation. Lightly rubbing the lower leg for redness and tenderness (Choice C) can potentially dislodge a clot if present. Dorsiflexing the foot while assessing for patient discomfort (Choice D) is not a specific assessment for DVT and may not provide relevant information in this context.
Question 5 of 5
While providing care to a group of patients, which patient should the nurse prioritize seeing first?
Correct Answer: A
Rationale: The nurse should prioritize seeing the patient with a hip replacement on prolonged bed rest reporting chest pain and dyspnea first. This patient is at higher risk for deep vein thrombosis due to prolonged bed rest, which can lead to a life-threatening embolus. Chest pain and dyspnea could also indicate a potential pulmonary embolism, which requires immediate assessment and intervention. The other patients, while requiring care, do not present with symptoms that suggest an immediate life-threatening situation, making them lower priority at this time. Therefore, option A is the correct choice as it addresses a potentially critical condition that requires immediate attention.
