HESI Fundamentals Practice Test

Correct Answer: B

Rationale: Administering 100% oxygen before and after suctioning is crucial to prevent hypoxia, which can occur during tracheal suctioning. Hypoxia can lead to serious complications, making the provision of oxygen essential in maintaining adequate oxygenation levels for the patient undergoing tracheal suctioning. Choice A is incorrect because using a water-soluble lubricant is not directly related to the essential nursing action during tracheal suctioning. Choice C is incorrect as ensuring that the suction catheter is open during insertion is a basic requirement and not the essential action for oxygenation. Choice D is incorrect because assisting the client to assume a semi-Fowler's position is beneficial for comfort and airway alignment but is not as crucial as administering oxygen to prevent hypoxia.

Correct Answer: B

Rationale: Engaging in moderate exercise for 30 minutes daily is a crucial lifestyle modification for managing hypertension. Regular physical activity helps lower blood pressure, improve cardiovascular health, and overall well-being. It is recommended to engage in activities like brisk walking, cycling, or swimming to achieve these benefits. Choices A, C, and D are incorrect. Limiting sodium intake, avoiding a diet high in saturated fats, and reducing alcohol consumption are also important lifestyle modifications for hypertension management, but engaging in moderate exercise is the most appropriate initial instruction for this client.

Correct Answer: B

Rationale: Kussmaul respirations (B) are a deep and labored breathing pattern associated with diabetic ketoacidosis (DKA) and are expected in this condition. While oliguria (A), fruity odor on the breath (C), and elevated blood glucose level (D) are also signs of DKA, Kussmaul respirations are more specific and critical to the condition, indicating severe metabolic acidosis.

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: B

Rationale: Acknowledging the client's feelings with empathy is essential in the early stage of adjustment to a colostomy surgery. By saying 'It must be difficult to have this kind of surgery,' the nurse validates the client's emotions and opens up a channel for further communication. Choice A is incorrect because agreeing with the client's denial is not therapeutic and may hinder acceptance. Choice C is inappropriate as it disregards the client's emotional state and autonomy. Choice D involves the surgeon and is not the nurse's role in addressing the client's emotional needs.
