HESI Fundamentals Study Guide

Correct Answer: B

Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.

Correct Answer: A

Rationale: The correct answer is A: Hypotension. Heat stroke is characterized by elevated body temperature, which can lead to hypotension (low blood pressure) due to dehydration and vasodilation. Bradycardia (slow heart rate) and clammy skin are not typical findings in heat stroke. Bradypnea (slow breathing) is also not a common feature of heat stroke. Therefore, hypotension is the most likely cardiovascular manifestation seen in a client with heat stroke.

Correct Answer: A

Rationale: In a client with paralytic ileus, absent bowel sounds with distention are expected due to decreased or absent bowel motility. This is a key characteristic of paralytic ileus, where the bowel is unable to contract and move contents along the digestive tract. Hyperactive bowel sounds (choice B) are more indicative of increased peristalsis, which is not typically seen in paralytic ileus. Normal bowel sounds (choice C) may not be present in a client with paralytic ileus. High-pitched bowel sounds (choice D) are not typically associated with paralytic ileus. Therefore, the correct assessment finding in this scenario is absent bowel sounds with distention.

Correct Answer: A

Rationale: Before administering morphine sulfate, it is crucial to measure the client's vital signs to ensure that the client is stable and safe to receive the medication. This step helps identify any contraindications or abnormalities that could affect the administration of morphine. Assessing the client's pain level (choice B) is important, but ensuring the client's physiological stability takes precedence. Verifying the morphine order with another nurse (choice C) and checking the client's last dose of morphine (choice D) are important steps but are not the priority before administering the medication.
