Community Health HESI Study Guide
1. Which one of the following statements, if made by the client, indicates teaching about Inderal (propranolol) has been effective?
- A. ''I may experience seizures if I stop the medication abruptly.''
- B. ''I may experience an increase in my heart rate for a few weeks.''
- C. ''I can expect to feel nervousness the first few weeks.''
- D. ''I can have a heart attack if I stop this medication suddenly.''
Correct answer: D
Rationale: The correct answer is D. Stopping Inderal (propranolol) abruptly can cause rebound hypertension, angina, and even a myocardial infarction (heart attack), so it is crucial to taper off the medication under medical supervision. Choices A, B, and C are incorrect because they do not reflect the serious consequences associated with abrupt discontinuation of propranolol.
2. 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.
3. A nurse in a pediatric unit is preparing to administer medication to a child. What should the nurse do to ensure the correct dosage?
- A. Check the child's weight
- B. Verify the medication order with a pharmacist
- C. Consult the child's parents
- D. Double-check the dosage calculations with another nurse
Correct answer: D
Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.
4. Which techniques should be used to administer an intradermal (ID) injection for a Mantoux test to screen for tuberculosis (TB)? Select all that apply.
- A. Observe for an intradermal bleed after the antigen is injected
- B. Select an ID site using the volar surface of the forearm
- C. Use a 26 or 27-gauge needle with a length of 1/4 to 5/8 inches on a 1 ml calibrated syringe
- D. Ensure that the needle is inserted into the skin with the bevel up
Correct answer: A
Rationale: Observing for an intradermal bleed after the antigen is injected is a proper technique for an ID injection. This is important to confirm the correct placement of the injection. Choice B is correct because the recommended site for an ID injection for a Mantoux test is the volar surface of the forearm. Choice C is incorrect because the standard needle size for an ID injection is usually 26 or 27 gauge with a length of 1/4 to 5/8 inches, not 25 gauge with a length of 1/2 inch. Choice D is incorrect because the needle should be inserted into the skin with the bevel facing up, not down.
5. A client has a terminal diagnosis and their health is declining. The client requests information about advance directives. Which of the following responses should the nurse make?
- A. Offering to discuss advance directives and provide brochures respects the client's request and provides information.
- B. Informing the client that advance directives are not necessary at this time is incorrect as they play a crucial role in end-of-life care.
- C. Scheduling a meeting with the family to discuss advance directives is not the most appropriate response as the client directly requested information.
- D. Directing the client to ask their provider about advance directives does not directly address the client's request for information.
Correct answer: A
Rationale: When a client with a terminal illness asks about advance directives, it is essential to provide the information they seek. Choice A is the correct response as it acknowledges the client's request and offers to discuss advance directives while providing additional resources in the form of brochures. This approach empowers the client to make informed decisions about their end-of-life care. Choices B, C, and D are incorrect because they do not directly address the client's request or provide the information the client is seeking. Choice B dismisses the importance of advance directives, which are crucial in end-of-life care planning. Choice C involves the family unnecessarily when the client directly requested information. Choice D deflects the responsibility back to the client to seek information from their provider instead of addressing their immediate request.
