HESI Fundamentals Exam
1. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?
- A. 80
- B. 8
- C. 21
- D. 25
Correct answer: C
Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.
2. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Place the tablet under your tongue and let it dissolve completely.
- C. Swallow the tablet whole with a glass of water.
- D. Chew the tablet for faster relief.
Correct answer: B
Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to place the tablet under the tongue and let it dissolve completely. This route of administration allows for rapid absorption of the medication through the oral mucosa, providing quick relief for angina symptoms. Option A, taking the medication with food, is incorrect as nitroglycerin should be taken sublingually, not with food. Option C, swallowing the tablet whole with water, is incorrect as sublingual tablets should not be swallowed whole. Option D, chewing the tablet for faster relief, is also incorrect as chewing the tablet can lead to rapid absorption and potential adverse effects rather than a controlled release for angina relief.
3. When teaching adult cardiopulmonary resuscitation (CPR) to a group of newly licensed nurses, what should the charge nurse instruct as the initial response in CPR?
- A. Confirm unresponsiveness
- B. Check for a pulse
- C. Begin chest compressions
- D. Call for emergency help
Correct answer: A
Rationale: The correct initial response in CPR is to confirm unresponsiveness. This step is crucial to ensure that the person actually needs CPR before proceeding with further actions. Checking for unresponsiveness is essential to determine if the individual is in need of immediate assistance. Checking for a pulse or beginning chest compressions without confirming unresponsiveness could waste valuable time and potentially harm the individual. Calling for emergency help is important, but it should follow the confirmation of unresponsiveness to ensure timely activation of emergency services.
4. A nurse overhears a colleague informing a client that he will administer her medication by injection if she refuses to swallow her pills. The nurse should recognize that the colleague is committing which of the following torts?
- A. Defamation - harming someone's reputation through false statements.
- B. Malpractice - professional negligence or misconduct.
- C. Assault - threatening to cause harm to someone.
- D. Battery - intentional harmful or offensive physical contact.
Correct answer: C
Rationale: In this scenario, the colleague's action of informing the client that he will administer medication by injection if she refuses to swallow her pills constitutes assault. Assault is the act of threatening harm that causes fear of imminent harm. It does not involve physical contact but rather the apprehension of an imminent harmful or offensive act. Defamation, choice A, is incorrect as it involves harming someone's reputation through false statements. Malpractice, choice B, is also incorrect as it refers to professional negligence or misconduct in performing duties. Battery, choice D, is not the correct answer as it involves intentional harmful or offensive physical contact with the person.
5. When should the client administer the inhaler-delivered medication to demonstrate correct use of the inhaler?
- A. Immediately after exhalation.
- B. During the inhalation.
- C. At the end of three inhalations.
- D. Immediately after inhalation.
Correct answer: B
Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.
