HESI Fundamentals Practice Test

Correct Answer: A

Rationale: After reviewing the expected outcomes identified in the plan of care, the nurse's next step should be to determine if these outcomes were realistic. This assessment helps in understanding if the goals set were achievable and appropriate for the client's condition before proceeding to compare them with current client data or modifying nursing interventions. By verifying the realism of the expected outcomes, the nurse ensures a solid foundation for further evaluation and adjustment of the care plan. Option B is incorrect because obtaining current client data comes after assessing the realism of the expected outcomes. Option C is incorrect because modifying nursing interventions should be based on the assessment of the expected outcomes' realism. Option D is incorrect as reviewing professional standards of care is important but not the immediate next step after assessing the expected outcomes' realism.

Correct Answer: B

Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse is the site for auscultation when the blood pressure cuff is applied around the thigh. Auscultating the popliteal pulse with the cuff on the lower leg is incorrect as it may lead to an inaccurate reading. Placing the client in a prone position and wrapping the cuff around the girth of the leg are acceptable practices. A systolic reading that is 20 mm Hg higher in the lower extremity compared to the arm is expected due to the difference in blood pressure between the upper and lower parts of the body.

Correct Answer: A

Rationale: Adolescents are particularly influenced by peers, so associating with non-smokers may help the student quit smoking. By being surrounded by non-smokers, the student is less likely to feel pressured to smoke and may be encouraged to adopt healthier behaviors. This intervention leverages the power of social influence to support smoking cessation efforts and create a more conducive environment for the student to quit smoking. Choices B, C, and D do not address the social aspect of smoking behavior and the influence of peers on smoking habits, making them less effective interventions in this case.

Correct Answer: C

Rationale: Coughing, vomiting, and suctioning can precipitate displacement of the tip of the small-bore feeding tube upward into the esophagus, placing the client at increased risk for aspiration. Checking the sample of fluid withdrawn from the tube (after clearing the tube with 30 ml of air) for acidic (stomach) or alkaline (intestine) values is a more sensitive method for these tubes. The nurse should assess tube placement in this way before taking any other action to ensure the tube is still in the correct position and prevent potential complications. Choice A is incorrect because further assessment is needed due to the risk of tube displacement. Choice B is incorrect as stopping the feeding and involving the family is premature without confirming tube placement. Choice D is incorrect as injecting air and auscultating for gurgling is not the recommended method to confirm tube placement.

Correct Answer: D

Rationale: In hypernatremia, there is an excess of sodium in the blood. Reviewing food labels for sodium content is crucial as it helps the client identify and avoid high-sodium foods, which can contribute to elevated sodium levels. Monitoring urine output volume may be important for other conditions but is not directly related to managing hypernatremia. Drinking water whenever thirsty is generally good advice for staying hydrated but does not specifically address the issue of high sodium levels. Using salt tablets would worsen hypernatremia by further increasing sodium intake.
