HESI Fundamentals Practice Exam

Correct Answer: D

Rationale: To determine the drops per minute for the client, first convert the client's weight from pounds to kilograms: 182/2.2 = 82.73 kg. Calculate the dosage by multiplying 5 mcg by the client's weight in kg: 5 mcg/kg/min 82.73 kg = 413.65 mcg/min. Find the concentration of the solution in mcg/ml by dividing 250 ml by 50,000 mcg (50 mg): 250 ml/50,000 mcg = 200 mcg/ml. As the client needs 413.65 mcg/min and the solution is 200 mcg/ml, the client should receive 2.07 ml per minute. Finally, using the drip factor of 60 gtt/ml, multiply the ml per minute by the drip factor: 60 gtt/ml 2.07 ml/min = 124.28 gtt/min, which rounds to 124 gtt/min. Therefore, the client should receive 124 drops per minute. Choice D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate calculation based on the client's weight, dosage, concentration of the solution, and drip factor.

Correct Answer: B

Rationale: During a fire evacuation, it is crucial for ambulatory clients to be reminded to walk carefully down the stairs. This helps ensure the safety of the client by preventing falls or injuries during the evacuation process. Directing the client to proceed cautiously down the stairs until reaching a lower floor provides necessary guidance to promote a safe evacuation process. Choice A is incorrect because assigning unlicensed assistive personnel to transport the client via a wheelchair may delay the evacuation process and increase the risk of injury. Choice C is incorrect as it distracts the ambulatory client from evacuating safely by involving them in assisting another client. Choice D is incorrect as opening fire doors may not be the most appropriate action at that moment; prioritizing safe evacuation procedures for ambulatory clients is essential.

Correct Answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

Correct Answer: D

Rationale: The correct instruction for a UAP caring for a client with MRSA under contact precautions is to don a gown and gloves when entering the client's room. This precaution is essential to prevent the spread of MRSA and protect both the client and the healthcare worker from potential infection. Choice A is incorrect because visitors should not be restricted solely based on contact precautions. Choice B is incorrect as wearing sterile gloves is not necessary, standard precautions with regular gloves are sufficient. Choice C is incorrect because the client wearing a mask is not a standard practice for contact precautions; it is the healthcare worker who should take preventive measures.

Correct Answer: C

Rationale: Limiting saturated fat from animal food sources to no more than 4 ounces per week is an important diet modification for lowering cholesterol. To be effective in reducing cholesterol, the client should exercise 30 minutes per day, or at least 4 to 6 times per week. Red meat and all proteins do not need to be eliminated to lower cholesterol, but should be restricted to lean cuts of red meat and smaller portions. The low density lipoproteins need to decrease rather than increase.
