HESI Fundamentals Study Guide Questions
Question 1 of 5
The healthcare professional is preparing to administer a medication through a nasogastric (NG) tube. Which action should the healthcare professional take to ensure proper administration?
Correct Answer: A
Rationale: Flushing the NG tube with water before and after medication administration is essential to ensure the tube is patent and prevent clogging. This action helps in clearing the tube and ensures that the medication is delivered properly. Administering medication with food (Choice B) may not be appropriate for all medications and can interfere with their absorption. Verifying tube placement by aspirating stomach contents (Choice C) is important but does not directly relate to ensuring proper medication administration. Diluting the medication with normal saline (Choice D) is not a standard practice for administering medications through an NG tube.
Question 2 of 5
During a follow-up visit, a home health nurse notices that a client with a gastrostomy tube, who receives intermittent feedings and medications, has developed diarrhea. Which of the following findings should the nurse identify as a possible cause of the diarrhea?
Correct Answer: A
Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.
Question 3 of 5
A healthcare professional is preparing to administer 0.9% sodium chloride (0.9% NaCl) 250 mL IV to infuse over 30 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
Correct Answer: C
Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL · 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.
Question 4 of 5
A client who is lactating is being taught about taking medications by a nurse. Which of the following actions should the nurse recommend to minimize the entry of medication into breast milk?
Correct Answer: C
Rationale: Taking medications immediately after breastfeeding helps minimize the amount of medication that enters breast milk. By doing so, there is a longer interval between the medication intake and the next breastfeeding session, reducing the concentration of the medication in breast milk. Options A and B are incorrect as drinking water with medication or using medications with a short half-life do not directly minimize the entry of medication into breast milk. Option D is unnecessary and wasteful as pumping and discarding breast milk before feeding is not as effective as timing medication intake with breastfeeding to reduce medication transfer into breast milk.
Question 5 of 5
A healthcare professional is preparing to inject heparin subcutaneously for a client who is postoperative. Which of the following actions should the healthcare professional take?
Correct Answer: B
Rationale: For subcutaneous injections like heparin, a 25-27 gauge needle is recommended, making choice A incorrect. The abdomen is a commonly used site for heparin injection due to its consistent absorption and convenience, making choice B the correct answer. The Z-track technique is not necessary for subcutaneous injections, making choice C unnecessary. Observing for bleb formation is not a standard practice for confirming proper placement of subcutaneous heparin, making choice D incorrect. Therefore, the correct action is to select a site on the client's abdomen for the injection.
