Fundamentals of Nursing HESI
1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
2. A nurse enters a client's room and finds her on the floor. The client's roommate reports that the client was trying to get out of bed and fell over the bedrail onto the floor. Which of the following statements should the nurse document about this incident?
- A. ''Incident report completed.''
- B. ''Client climbed over the bedrails.''
- C. ''Client found lying on the floor.''
- D. ''Client was trying to get out of bed.''
Correct answer: C
Rationale: The correct answer is C: ''Client found lying on the floor.'' In this situation, the nurse should document factual, objective information without making assumptions. Stating that the client was found lying on the floor directly reflects what was observed. Choice A, ''Incident report completed,'' is not a statement about the incident itself and does not provide relevant information. Choice B, ''Client climbed over the bedrails,'' introduces unnecessary speculation and assumption which should be avoided when documenting incidents. Choice D, ''Client was trying to get out of bed,'' focuses on the client's behavior rather than the objective observation of the client's position when found.
3. During an admission assessment, a healthcare professional finds a client's radial pulse rate to be 68/min and the simultaneous apical pulse to be 84/min. What is the client’s pulse deficit (per minute)?
- A. 16
- B. 12
- C. 6
- D. 14
Correct answer: A
Rationale: The pulse deficit is calculated by finding the difference between the apical and radial pulse rates. In this case, the difference is 84 - 68 = 16. This indicates that there is a pulse deficit of 16 beats per minute. Choices B, C, and D are incorrect as they do not accurately reflect the difference between the two pulse rates.
4. A healthcare professional is assessing a client’s extraocular eye movements. Which of the following should the professional do?
- A. Instruct the client to follow a finger through the six cardinal positions of gaze.
- B. Hold a finger 46 cm (18 in) away from the client’s eyes.
- C. Ask the client to cover their right eye during assessment of the left eye.
- D. Position the client 6.1 m (20 feet) away from the Snellen chart.
Correct answer: A
Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action when assessing extraocular eye movements. This technique assesses the movement of the eyes in all directions and helps to test cranial nerves 3, 4, and 6, which control eye movements. Choice B is incorrect as the distance mentioned is not relevant for assessing extraocular eye movements. Choice C is incorrect as both eyes need to be assessed independently. Choice D is incorrect as positioning the client 6.1 m (20 feet) away from the Snellen chart is related to visual acuity testing, not extraocular eye movements.
5. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?
- A. Muscle weakness
- B. Joint pain
- C. Vision changes
- D. Skin rash
Correct answer: A
Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).
