HESI Fundamentals Exam

Correct Answer: A

Rationale: The correct answer is A. Taking warfarin at the same time every day is essential to maintain a consistent blood level of the medication. This statement indicates that the client understands the teaching about the importance of consistency in medication timing. Choice B, regarding using a soft-bristled toothbrush, is not directly related to warfarin therapy and does not assess the client's understanding of warfarin administration. Choice C suggesting taking warfarin at bedtime is incorrect; it is generally recommended to take warfarin at the same time each day to avoid variations in drug levels. Choice D about avoiding foods high in vitamin K is relevant as vitamin K can interfere with warfarin's anticoagulant effects. However, it is not the best indicator of understanding the teaching on medication timing, which is crucial for warfarin efficacy.

Correct Answer: B

Rationale: The correct answer is B. Asking the client if they want to schedule prayer times during the day demonstrates respect and consideration for Islamic practices. Providing halal options (choice A) is important for dietary requirements in Islam, but it may not address the client's spiritual needs. Avoiding discussing care in front of the client's family (choice C) is not directly linked to Islamic practices and may not necessarily enhance cultural responsiveness. Offering daily communion (choice D) is associated with Christian religious practices, not Islamic practices, and may not meet the client's religious needs.

Correct Answer: A

Rationale: When a client is using a nasal cannula for oxygen therapy, the areas prone to skin damage are the tops of the ears and around the nostrils. The pressure exerted by the cannula on these areas can lead to skin breakdown, so it is important for the nurse to observe these sites for any signs of damage. The correct answer is 'Tops of the ears.' Choices 'Bridge of the nose' and 'Over the cheeks' are not typically areas where skin damage related to the cannula would occur, making them incorrect choices.

Correct Answer: A

Rationale: Paralytic ileus is a condition where there is a temporary paralysis of the bowel, leading to absent bowel sounds and abdominal distention. This occurs because the bowel is not functioning properly to propel contents, resulting in a lack of bowel sounds. Absent bowel sounds with distention are typical findings in paralytic ileus. Hyperactive bowel sounds with pain are more indicative of increased motility and are not expected in paralytic ileus. Normal bowel sounds with cramping may be seen in other conditions, such as gastroenteritis. Diminished bowel sounds with tenderness are not typical findings in paralytic ileus.

Correct Answer: B

Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.
