HESI LPN

1. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, “Amoxicillin (Amoxil) suspension 200 mg/5 ml.” How many ml should the nurse administer every 8 hours? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

• A. 12.5
• B. 7.5
• C. 10.0
• D. 15.0

Correct Answer: A

Rationale: To calculate the amount in ml that the nurse should administer every 8 hours, first, determine the amount of amoxicillin needed per dose. 1.5 grams daily divided by 3 doses equals 0.5 grams per dose. Since 0.5 grams is equivalent to 500 mg (1 gram = 1000 mg), and each 5 ml of the suspension contains 200 mg of amoxicillin, the nurse needs to administer (500 mg / 200 mg) * 5 ml = 12.5 ml every 8 hours. Therefore, the correct answer is 12.5 ml. Choices B, C, and D are incorrect because they do not reflect the accurate calculation based on the provided information.

2. An 18-year-old gravida 1, at 41-weeks gestation, is undergoing an oxytocin (Pitocin) induction and has an epidural catheter in place for pain control. With each of the last three contractions, the nurse notes a late deceleration. The client is repositioned, and oxygen provided, but the late decelerations continue to occur with each contraction. What action should the nurse take first?

• A. Prepare for immediate cesarean birth
• B. Turn off the oxytocin (Pitocin) infusion
• C. Notify the anesthesiologist that the epidural infusion needs to be disconnected
• D. Apply an internal fetal monitoring device and continue to monitor carefully

Correct Answer: B

Rationale: In the scenario described, the nurse notes late decelerations during contractions despite repositioning and oxygen administration. Late decelerations are often associated with uteroplacental insufficiency, which can be exacerbated by increased uterine activity stimulated by oxytocin. The initial action to manage late decelerations is to turn off the oxytocin infusion to reduce uterine stimulation. This step aims to improve fetal oxygenation and prevent further stress on the fetus. Immediate cesarean birth may be necessary if the late decelerations persist or worsen despite discontinuing the oxytocin infusion. Notifying the anesthesiologist to disconnect the epidural infusion or applying an internal fetal monitoring device are not the first-line interventions for managing late decelerations.

3. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client’s right leg?

• A. Dorsiflexes the right foot and left foot on command
• B. A 3 by 5 cm ecchymosis area on the right calf
• C. Right calf is 3 cm larger in circumference than the left calf
• D. Bilateral lower extremities have 3+ pitting edema

Correct Answer: C

Rationale: The correct answer is C because a significant difference in calf circumference between the legs is a classic sign of DVT. This is due to the obstruction of blood flow in the deep veins of the leg, leading to swelling in the affected limb. Choices A, B, and D are not typical findings of DVT. Choice A describes a neurological response, choice B indicates a bruise on the right calf, and choice D describes pitting edema in both lower extremities, which are not specific signs of DVT.

4. Before administering an intramuscular injection, the nurse's finger is stuck with the needle. Which action should the nurse take?

• A. Go to the emergency room to have blood drawn
• B. Prepare the medication using a new syringe
• C. Apply clean gloves before giving the medication
• D. Review the medical history in the client's chart

Correct Answer: B

Rationale: In this scenario, if the nurse's finger is stuck with the needle before administering the injection, the correct action is to prepare the medication using a new syringe. This step is crucial to prevent contamination and ensure the safety of the patient. Going to the emergency room to have blood drawn is unnecessary and does not address the immediate issue of contamination. Applying clean gloves is important for infection control but does not address the potential contamination from the needlestick. Reviewing the medical history in the client's chart is important for overall patient care but is not the priority in this situation where immediate action is required to prevent harm.

5. While eating at a restaurant, a gravid woman begins to choke and is unable to speak. What action should the nurse who witnesses the event take?

• A. Cardiopulmonary resuscitation with uterine tilt
• B. The Heimlich maneuver using chest thrusts
• C. The Heimlich maneuver using subdiaphragmatic thrusts
• D. Call 911 immediately then begin cardiopulmonary resuscitation

Correct Answer: C

Rationale: The correct action for the nurse to take when a pregnant woman is choking and unable to speak is to perform the Heimlich maneuver using subdiaphragmatic thrusts. This technique is recommended for a pregnant woman to prevent harm to the fetus. Option A, cardiopulmonary resuscitation with uterine tilt, is not indicated for a choking episode. Option B, the Heimlich maneuver using chest thrusts, can potentially harm the gravid uterus. Option D, calling 911 immediately before providing assistance, can lead to a delay in addressing the immediate choking emergency.
