HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can lead to bradycardia. Bradycardia is a common adverse effect associated with digoxin toxicity. Blood pressure of 140/90 mmHg, respiratory rate of 20 breaths per minute, and blood glucose level of 150 mg/dL are within normal limits and would not warrant withholding the medication or contacting the healthcare provider in this context. Therefore, a heart rate of 55 beats per minute would prompt the nurse to withhold digoxin and notify the healthcare provider.

Correct Answer: B

Rationale: The correct answer is B because as a witness, the nurse's primary responsibility is to confirm that the signature on the preoperative consent form belongs to the client. The nurse is not confirming the client's understanding of the procedure (Choice A), but rather the authenticity of the signature. Choice C is incorrect because the nurse is not responsible for verifying that the procedure has been explained, but rather confirming the client's signature. Similarly, Choice D is incorrect because the nurse's role as a witness is not to ensure the client is aware of potential complications, but to verify the signature.

Correct Answer: A

Rationale: The correct answer is to flush the tube before and after each medication administration. This helps prevent clogging and ensures the medication is delivered properly. Mixing medications with enteral feeding (choice B) is incorrect as medications should be administered separately. Pushing tablets through the tube (choice C) is not recommended as they should be properly dissolved before administration. Mixing all crushed medications before dissolving them in water (choice D) is incorrect; medications should be dissolved individually to avoid interactions or inconsistencies in dosages.

Correct Answer: B

Rationale: Placing the client's arm in a dependent position is the correct action when inserting a peripheral IV catheter for an older adult client. This position helps veins dilate due to gravity, facilitating easier insertion of the IV catheter. Choice A is incorrect because catheters are typically inserted at a lower angle, around 10-30 degrees. Choice C is unnecessary unless excessive hair impedes the insertion process. Choice D is incorrect as veins in the hand are generally smaller and more prone to complications, making them less ideal for IV therapy in older adults.

Correct Answer: A

Rationale: The correct statement for the nurse to make to the client is to 'Donate autologous blood before the surgery.' Autologous blood donation involves collecting and storing the client's own blood for potential use during surgery, which significantly reduces the risk of transfusion-related infections. This option directly addresses the client's concern about infection risk. Requesting a specific blood type from a donor (Choice B) is not as effective in reducing infection risk compared to autologous blood donation. Using blood from a family member (Choice C) carries the risk of transfusion reactions and infections due to compatibility issues. Accepting allogeneic blood without concerns (Choice D) does not address the client's specific concern about infection risk and is not the most appropriate option in this situation.
