Practice HESI Fundamentals Exam

Correct Answer: A

Rationale: An albumin level below 3.5 g/dL indicates protein deficiency, which can impair wound healing and contribute to pressure ulcer formation. Hemoglobin level and WBC count are not directly associated with pressure ulcers. Blood glucose level, while important for overall health, is not specifically linked to pressure ulcer development.

Correct Answer: D

Rationale: Using surgical asepsis when performing nasal tracheal suctioning is crucial to prevent infection. Choice A is incorrect because the suction catheter should be held with the dominant hand to ensure better control and precision during the procedure. Choice B is incorrect as suctioning should be applied for no longer than 10 to 15 seconds to avoid trauma to the mucous membranes. Choice C is incorrect as the catheter should be disposed of properly after single-use to prevent cross-contamination and infection.

Correct Answer: B

Rationale: A saturated abdominal dressing is a critical finding that may indicate active bleeding or wound complications. Immediate intervention is necessary to prevent further complications, such as hypovolemic shock or infection. Absent bowel sounds, though abnormal, are a common post-operative finding and do not require immediate intervention. Pain level of 8/10 can be managed effectively with appropriate pain control measures and does not indicate an urgent issue. A temperature of 100.4�F is slightly elevated but may be a normal post-operative response to surgery and does not typically require immediate intervention unless accompanied by other concerning signs or symptoms.

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: 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.
