HESI Fundamentals Practice Exam

Correct Answer: B

Rationale: After ensuring the correct placement of the NGT, the nurse should flush the tube with water to prevent any obstructions and ensure proper medication delivery. Flushing the tube is essential before, after, and in between each medication administration. Clamping the tube for 20 minutes should be done after all medications are administered to prevent clogging. Administering medications as prescribed and preparing medications by crushing tablets and dissolving them in sterile water should only be done after the tube has been appropriately flushed to maintain its patency and effectiveness.

Correct Answer: C

Rationale: To assess fever patterns accurately, the nurse should measure the client's temperature at regular intervals. This approach helps in identifying the pattern of fever spikes and fluctuations, which can provide valuable information for diagnostic and treatment purposes. Assessing for flushed, warm skin or documenting circadian rhythms may not directly reveal the fever pattern, while varying temperature measurement sites could lead to inconsistent readings. Therefore, measuring temperature at regular intervals is the most appropriate intervention to identify fever patterns in this scenario.

Correct Answer: A

Rationale: When a person is struck by lightning, it can cause an electrical shock that may affect the heart rhythm. Therefore, assessing pulse characteristics is crucial as lightning can act as a natural defibrillator. Monitoring the pulse rate and regularity will help determine if there are any cardiac abnormalities that need immediate attention. Open airway, entrance and exit wounds, and cervical spine injury assessments are also important but assessing pulse characteristics takes precedence in this situation to address potential cardiac issues.

Correct Answer: D

Rationale: To determine the drops per minute for the client, first convert the client's weight from pounds to kilograms: 182/2.2 = 82.73 kg. Calculate the dosage by multiplying 5 mcg by the client's weight in kg: 5 mcg/kg/min 82.73 kg = 413.65 mcg/min. Find the concentration of the solution in mcg/ml by dividing 250 ml by 50,000 mcg (50 mg): 250 ml/50,000 mcg = 200 mcg/ml. As the client needs 413.65 mcg/min and the solution is 200 mcg/ml, the client should receive 2.07 ml per minute. Finally, using the drip factor of 60 gtt/ml, multiply the ml per minute by the drip factor: 60 gtt/ml 2.07 ml/min = 124.28 gtt/min, which rounds to 124 gtt/min. Therefore, the client should receive 124 drops per minute. Choice D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate calculation based on the client's weight, dosage, concentration of the solution, and drip factor.

Correct Answer: A

Rationale: In obtaining a lie-sit-stand blood pressure reading, it is crucial for the healthcare professional to stay with the client while the client is standing. This action is the most important as it ensures client safety during the procedure. Recording findings, keeping the blood pressure cuff on the same arm, and monitoring pulse rate are all important tasks, but staying with the client while standing takes priority to prevent any potential falls or adverse events. By staying with the client, the healthcare professional can promptly address any signs of dizziness or instability, ensuring a safe environment for the client throughout the procedure.
