HESI Fundamentals Study Guide

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.

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: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.

Correct Answer: D

Rationale: The correct answer is to further assess the patient. 'ROM as needed' stands for Range of Motion, indicating that the patient should have their limbs moved to maintain joint flexibility and muscle strength. Before initiating any movements, it is crucial to assess the patient's current condition to determine their abilities and limitations. Restricting mobility (choice A) is not appropriate as it contradicts the purpose of ROM exercises. Realizing the patient is unable to move extremities (choice B) assumes without assessment and can lead to inappropriate care. Moving all the patient's extremities (choice C) without assessing the patient first can be harmful, as it may cause pain or injury if done incorrectly. Therefore, further assessment is necessary to provide safe and effective care.

Correct Answer: C

Rationale: The correct answer is C: Pressure injury. Prolonged sitting can lead to pressure injuries due to continuous pressure on certain body areas, reducing blood flow and causing tissue damage. While decreased subcutaneous fat, muscle atrophy, and fecal impaction are potential concerns, pressure injuries pose the greatest immediate risk as they can lead to serious complications such as tissue necrosis and infection if not addressed promptly. Decreased subcutaneous fat and muscle atrophy may develop over time with prolonged immobility but are not as acutely dangerous as a pressure injury. Fecal impaction, while uncomfortable and potentially serious, does not pose an immediate life-threatening risk compared to the development of a pressure injury.
