Fundamentals of Nursing HESI

1. What is the rate of delivery in mL/hr if a total volume of 750 mL is infused over a period of 7 hours?

A. 107 mL/hr.
B. 107 mL/hr.
C. 107 mL/hr.
D. 107 mL/hr.

Correct answer: A

Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.

2. The healthcare provider retrieves hydromorphone 4mg/mL from the Pyxis MedStation, an automated dispensing system, for a client who is receiving hydromorphone 3 mg IM every 6 hours PRN for severe pain. How many mL should the healthcare provider administer to the client?

A. 0.75 mL
B. 1 mL
C. 0.8 mL
D. 1.2 mL

Correct answer: C

Rationale: The correct dosage calculation is to divide the prescribed dose by the concentration of the medication to determine the volume needed. In this case, 3 mg (prescribed dose) divided by 4 mg/mL (concentration) equals 0.75 mL. Therefore, the healthcare provider should administer 0.75 mL of hydromorphone to the client. Choices A, B, and D are incorrect because they do not accurately calculate the required volume based on the prescription and concentration provided.

3. During a patient assessment, which principle should be a priority?

A. Foot care is always important.
B. Daily bathing is always important.
C. Hygiene needs are always important.
D. Critical thinking is always important.

Correct answer: D

Rationale: During a patient assessment, critical thinking is a priority because a patient's condition can change rapidly, necessitating continuous critical thinking and adaptation of nursing interventions. While foot care, daily bathing, and hygiene needs are important components of patient care, they may not always take precedence over critical thinking, which guides the nurse in making timely and appropriate decisions based on the patient's current condition and needs. Therefore, critical thinking stands out as the most crucial principle during patient assessments.

4. A client with a history of seizures is prescribed phenytoin (Dilantin). Which statement should the LPN/LVN include when teaching the client about this medication?

A. Do not take the medication with milk to avoid reduced absorption.
B. Brush and floss your teeth regularly to prevent gum disease.
C. Avoid taking antacids within 2 hours of the medication.
D. Report any unusual bleeding or bruising to the healthcare provider.

Correct answer: C

Rationale: The correct answer is to avoid taking antacids within 2 hours of phenytoin. Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. Choice A is incorrect because phenytoin should not be taken with milk, as it may decrease its absorption. Choice B is unrelated to the medication and focuses on dental hygiene. Choice D is important but not directly related to phenytoin; it is more relevant to monitoring for adverse effects of the medication.

5. An assistive personnel tells the nurse, 'I am unable to find a large blood pressure cuff for a client who is obese. Can I just use the regular cuff if I can get it to stay on?' The nurse replies that taking the blood pressure of a morbidly obese client with a regular blood pressure cuff will result in a reading that is:

A. Low
B. High
C. Inaccurate
D. Unaffected

Correct answer: B

Rationale: Using a regular blood pressure cuff on a morbidly obese client will lead to a falsely high blood pressure reading. This occurs because the cuff is not appropriately sized for the client's arm circumference, resulting in increased pressure on the artery and an inaccurate high reading. Choice A is incorrect because the reading will be falsely high, not low. Choice C is incorrect as the reading will not be accurate with an incorrectly sized cuff. Choice D is incorrect because the reading will be affected by using the wrong cuff size.
