HESI Fundamentals Study Guide

Correct Answer: A

Rationale: In a situation where a client is found unresponsive on the floor, the nurse's first priority is to establish an airway. This is crucial to ensure that the client can breathe adequately and receive oxygen. Without a patent airway, the client's oxygenation and ventilation may be compromised, leading to serious consequences. Calling for assistance is important, but establishing an airway takes precedence as it directly impacts the client's ability to breathe. Checking the client's pulse and blood pressure can be done after ensuring a clear airway. Performing CPR is not the immediate action needed unless the client's breathing and pulse are absent after the airway has been secured.

Correct Answer: C

Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL � 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.

Correct Answer: C

Rationale: During a thoracic examination, normal findings should include resonance, which is the expected sound when percussing the thorax. Resonance indicates healthy lung tissue and air-filled spaces. Abnormal findings such as rhonchi and crackles suggest issues like lung congestion or inflammation. Tactile fremitus refers to vibrations felt on the chest wall during palpation and is not typically assessed during percussion and auscultation of the thorax.

Correct Answer: D

Rationale: The correct answer is D, Parenteral albumin (Albuminar). Parenteral albumin is not typically indicated for dehydration resulting from diarrhea. In this case, fluid replacement therapy with intravenous fluids such as parenteral half normal saline would be more appropriate. Oral psyllium and oral potassium supplement are not the primary interventions for managing dehydration due to watery diarrhea. Oral psyllium is a fiber supplement used for constipation rather than diarrhea. Oral potassium supplements may be necessary if potassium levels are low due to dehydration, but the priority is fluid replacement. Therefore, choices A and B are less relevant in this scenario.

Correct Answer: A

Rationale: The correct answer is A because severe pain can hinder the client's ability to participate effectively in learning. Pain can be distracting and may prevent the client from focusing on acquiring new information or skills. Choice B is incorrect because asking for a demonstration shows an interest in learning and readiness to understand the exercises. Choice C is incorrect as inquiring about potential complications indicates the client's engagement in understanding the procedure and its outcomes, demonstrating readiness to learn. Choice D is incorrect as agreeing to the procedure does not necessarily reflect a lack of readiness to learn. The client may still be open to receiving information about postoperative care, indicating a level of readiness to learn despite agreeing to the surgery.
