Practice HESI Fundamentals Exam

Correct Answer: B

Rationale: Correct placement of an NG tube is confirmed by aspirating gastric fluid, which indicates that the tube is in the stomach. An x-ray can help visualize tube placement, but it alone does not confirm correct placement. Flushing the tube with sterile water without resistance indicates patency but not necessarily correct placement. The absence of coughing or choking does not confirm tube placement and is more related to the client's comfort during the procedure.

Correct Answer: A

Rationale: Addressing the client's daily needs and concerns is a priority to help alleviate anxiety and ensure the client understands the immediate post-MI care. Daily needs and concerns encompass basic aspects like comfort, hygiene, emotional support, and overall well-being, which are crucial in the early recovery phase post-MI. Discussing cardiac rehabilitation, medication and diet guidelines, or activity and rest guidelines are important topics but addressing immediate personal needs and concerns takes precedence to establish a supportive and informative care environment.

Correct Answer: A

Rationale: Choice A, '8 oz of ice chips,' is the correct answer. 8 oz is equivalent to approximately 240 mL, and since 1 oz is roughly equal to 30 mL, 8 oz would be approximately 240 mL. Since the question specifies 120 mL of fluid, this option does not match. Choices C and D, '1 cup of broth,' do not equate to 120 mL. A standard cup is approximately 240 mL, which is double the amount mentioned in the question. Therefore, choice A is the most accurate representation of 120 mL of fluid intake.

Correct Answer: B

Rationale: The most appropriate initial approach to correct the behavior of improper hand washing by a staff nurse is to discuss what the nurse knows about proper hand hygiene. This approach helps in identifying any knowledge gaps the nurse may have and provides an opportunity to educate and correct the behavior. Option A is not the best choice as simply reminding the nurse about the importance of hand washing may not address the underlying issue of knowledge or technique. Option C, providing a review of the hand washing policy, may be necessary but is not the most immediate step to take. Option D, referring the nurse to the infection control nurse, is premature and may not be necessary if the issue can be resolved through education and communication first.

Correct Answer: B

Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action to assess extraocular eye movements effectively. This technique evaluates the function of the six extraocular muscles and cranial nerves III, IV, and VI. Positioning the client 6.1 m away from the Snellen chart is more relevant for visual acuity testing. Asking the client to cover their right eye during the assessment is not necessary for evaluating extraocular movements. Holding a finger at a specific distance in front of the client's eye is not an appropriate method for assessing extraocular eye movements.
