HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is to wear a gown when caring for the client. Shigellosis is highly contagious, and contact precautions are essential to prevent the spread of infection. Wearing gloves alone may not provide adequate protection as the client's diarrhea can contain infectious pathogens that can easily spread. Standard precautions include hand hygiene, but specific precautions for shigellosis require wearing a gown to protect against contact with infectious material. Wearing a mask and face shield are not necessary for shigellosis, as the primary mode of transmission is through the fecal-oral route, and these precautions are not indicated for this type of transmission.

Correct Answer: B

Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.

Correct Answer: A

Rationale: The correct action to take first when observing blue fingers in a client with wrist restraints is to loosen the right wrist restraint. Blue fingers indicate compromised circulation, and loosening the restraint can help restore blood flow to the area. Applying a pulse oximeter (Choice B) or palpating the right radial pulse (Choice D) may be necessary following the loosening of the restraint to assess the client's oxygen saturation and pulse. Comparing hand color bilaterally (Choice C) is important but not the immediate action needed when a circulation issue is noted in one hand.

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: 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.
