HESI CAT Exam Quizlet

HESI LPN

1. Which instruction is most important for the client who receives a new prescription for risedronate sodium to treat osteoporosis?

A. Remain upright for 30 minutes after taking the medication
B. Increase intake of foods rich in vitamin D
C. Begin a low-impact exercise routine
D. Take the medication with a full glass of water

Correct answer: A

Rationale: The most important instruction for a client receiving risedronate sodium to treat osteoporosis is to remain upright for 30 minutes after taking the medication. Risedronate sodium can cause esophageal irritation, and staying upright helps prevent this side effect. While increasing vitamin D intake, starting a low-impact exercise routine, and taking the medication with a full glass of water are all beneficial for managing osteoporosis, the immediate need is to prevent esophageal irritation caused by risedronate sodium.

2. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?

A. 5
B. 10
C. 15
D. 20

Correct answer: A

Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.

3. An older adult male is admitted with complications related to chronic obstructive pulmonary disease (COPD). He reports progressive dyspnea that worsens on exertion, and his weakness has increased over the past month. The nurse notes that he has dependent edema in both lower legs. Based on these assessment findings, which dietary instruction should the nurse provide?

A. Restrict daily fluid intake
B. Eat meals at the same time daily
C. Maintain a low-protein diet
D. Limit the intake of high-calorie foods

Correct answer: A

Rationale: Dependent edema in both lower legs is a sign of fluid overload, which can exacerbate dyspnea in patients with COPD. Restricting daily fluid intake can help reduce the edema and alleviate breathing difficulties. A low-protein diet is not necessary unless there are specific renal concerns. Eating meals at the same time daily or limiting high-calorie foods is not directly associated with addressing fluid overload and dyspnea in COPD patients.

4. A client who had an intraosseous (IO) cannula placed by the healthcare provider for emergent fluid resuscitation is complaining of severe pain and numbness below the IO site. The skin around the site is pale and edematous. What action should the nurse take first?

A. Discontinue the IO infusion
B. Administer an analgesic via the IO site
C. Elevate the extremity with the IO site
D. Notify the healthcare provider

Correct answer: A

Rationale: The correct action for the nurse to take first is to discontinue the IO infusion. The client's symptoms of severe pain, numbness, pale skin, and edema below the IO site suggest a complication, such as extravasation or compartment syndrome. By discontinuing the infusion, further harm can be prevented. Administering an analgesic via the IO site or elevating the extremity would not address the underlying issue and could potentially worsen the condition. Notifying the healthcare provider can be done after stopping the infusion to seek further guidance or intervention.

5. Based on the information provided in this client’s medical record during labor, which intervention should the nurse implement?

A. Apply oxygen at 10 L per minute via mask
B. Stop the oxytocin infusion
C. Turn the client to the right lateral position
D. Continue monitoring the progress of labor

Correct answer: C

Rationale: Turning the client to the right lateral position is essential as it can improve fetal oxygenation and uterine blood flow, promoting better labor outcomes. This intervention helps relieve pressure on blood vessels, enhancing blood flow to the placenta and improving oxygen supply to the fetus. Applying oxygen at a specific rate may not address the underlying issue of compromised blood flow and oxygenation. Stopping the oxytocin infusion is not the priority unless medically indicated as it can affect labor progression. While monitoring the progress of labor is important, actively addressing the compromised fetal oxygenation and uterine blood flow by changing the client's position takes precedence in this scenario.
