HESI Fundamental Practice Exam
1. A healthcare professional is preparing to insert an IV catheter into a client’s arm prior to initiating IV fluid therapy. Which of the following interventions should the healthcare professional implement to prevent infection?
- A. Thread the catheter up to the hub
- B. Use a sterile technique throughout the procedure
- C. Clean the insertion site with alcohol only
- D. Use gloves but not a mask during the procedure
Correct answer: B
Rationale: Using a sterile technique throughout the procedure is essential to prevent infection when inserting an IV catheter. This includes maintaining aseptic conditions, using sterile equipment, and following proper hand hygiene practices. Choice A is incorrect because threading the catheter up to the hub does not specifically address infection prevention. Choice C is incorrect as cleaning the insertion site with alcohol only may not provide adequate disinfection, as it is essential to use an antiseptic solution to reduce microbial load. Choice D is incorrect as wearing gloves alone is not sufficient protection against infection; a mask should also be worn to prevent the spread of microorganisms through respiratory secretions.
2. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?
- A. Inhibits pepsin production
- B. Stimulates hydrochloric acid production
- C. Delays stomach emptying time
- D. Reduces hydrochloric acid production
Correct answer: B
Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.
3. A nurse manager is overseeing the care on a unit. Which of the following should the nurse manager identify as a violation of HIPAA guidelines?
- A. A nurse who is caring for a client reviews the client's medical chart with the nursing student who is working with the nurse.
- B. A nurse asks a nurse from another unit to assist with her documentation.
- C. A nurse who is caring for a client returns a call to the client's durable power of attorney for health care designee to discuss the client's care.
- D. A nurse discusses a client's status with the physical therapist who is caring for the client at the bedside.
Correct answer: B
Rationale: The correct answer is B. HIPAA guidelines specify that only healthcare professionals directly involved in a patient's care should access their medical information. Asking a nurse from another unit to assist with documentation involves sharing patient information with someone not directly caring for the patient, which violates HIPAA guidelines. Choices A, C, and D involve individuals directly involved in the client's care, making them appropriate actions in line with HIPAA regulations. Choice A involves educating a nursing student under the supervision of the nurse, which is permissible. Choice C involves communicating with the client's designated healthcare decision-maker, which is also allowed under HIPAA. Choice D involves discussing the client's status with another healthcare professional directly involved in the client's care, which is within HIPAA guidelines.
4. A healthcare professional is reviewing a plan of care for a client who was admitted with dehydration as a result of prolonged watery diarrhea. Which prescription should the healthcare professional question?
- A. Oral psyllium (Metamucil)
- B. Oral potassium supplement
- C. Parenteral half normal saline
- D. Parenteral albumin (Albuminar)
Correct answer: D
Rationale: The correct answer is D, Parenteral albumin (Albuminar). Parenteral albumin is not typically indicated for dehydration resulting from diarrhea. In this case, fluid replacement therapy with intravenous fluids such as parenteral half normal saline would be more appropriate. Oral psyllium and oral potassium supplement are not the primary interventions for managing dehydration due to watery diarrhea. Oral psyllium is a fiber supplement used for constipation rather than diarrhea. Oral potassium supplements may be necessary if potassium levels are low due to dehydration, but the priority is fluid replacement. Therefore, choices A and B are less relevant in this scenario.
5. A nurse is caring for a client who has a surgical wound. Which of the following laboratory values places the client at risk for poor wound healing?
- A. Serum albumin 3 g/dL
- B. Total lymphocyte count 2400/mm3
- C. HCT 42%
- D. HGB 16 g/dL
Correct answer: A
Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.
