Practice HESI Fundamentals Exam

Correct Answer: B

Rationale: The correct answer is B. Clients with GERD should avoid coffee as it can relax the lower esophageal sphincter and exacerbate symptoms. Limiting coffee consumption to the morning hours may not be sufficient, as coffee can still contribute to GERD symptoms throughout the day. Choices A, C, and D are all appropriate strategies for managing GERD symptoms. Avoiding large meals before bedtime, elevating the head of the bed while sleeping, and steering clear of spicy and acidic foods are all recommended practices to help alleviate GERD symptoms. Therefore, the client's statement in option B indicates a need for further teaching to completely address dietary modifications for managing GERD.

Correct Answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

Correct Answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg � 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

Correct Answer: A

Rationale: Acknowledging that the client's wife is supporting the arm correctly is the appropriate nursing action in this scenario. By doing so, the nurse reinforces correct technique and promotes confidence. Choice B is incorrect as the issue is not about maintaining warmth. Choice C is incorrect as gripping directly under the joint is not necessary in this case. Choice D is incorrect as instructing to grip directly over the joint may not provide the best support for passive range-of-motion exercises.

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.
