Practice HESI Fundamentals Exam

Correct Answer: C

Rationale: The correct first action for the school nurse to take when a child is injured and appears to have a fractured leg is to assess the child and the extent of the injury. This initial assessment is crucial to determine the severity of the injury before proceeding with further interventions. Option A, calling for emergency transport, should only be done after assessing the extent of the injury. Option B, immobilizing the limb and joints, is important but should come after the initial assessment. Option D, applying cold compresses, is not recommended for suspected fractures as it can exacerbate swelling and pain.

Correct Answer: A

Rationale: Correct Answer: Large doses of acetaminophen can cause liver damage, which is a known adverse effect of the medication. Acetaminophen is metabolized in the liver, and excessive amounts can overwhelm the liver's ability to process it, leading to hepatotoxicity. Renal failure (Choice B) is not typically associated with acetaminophen use. Gastric bleeding (Choice C) is more commonly linked to nonsteroidal anti-inflammatory drugs (NSAIDs) rather than acetaminophen. Heart attack (Choice D) is not a recognized adverse effect of acetaminophen, which primarily affects the liver when taken in large amounts.

Correct Answer: C

Rationale: In the scenario described, the client has a living will that declines resuscitation. Therefore, if the client arrives at the emergency department with difficulty breathing, healthcare providers would consult the living will to understand the client's wishes. Providing comfort care, which may include oxygen therapy to alleviate symptoms, aligns with the client's preferences. Option A incorrectly suggests an intervention that goes against the client's wishes. Option B is incorrect because full resuscitation efforts are not in line with the client's choice to decline resuscitation. Option D is also incorrect as it does not consider the client's living will and the need to provide care according to the documented preferences of the client.

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: The nurse should focus on decreased pain sensation and increased risk of skin impairment due to the patient's conditions. Peripheral neuropathy can lead to decreased pain sensation, making the patient more prone to injuries without realizing it. Additionally, the combination of circulatory insufficiency, peripheral neuropathy, and urinary incontinence can increase the risk of skin breakdown and impaired healing. Choices B, C, and D are incorrect because they do not address the specific issues related to the patient's diagnoses and symptoms.
