HESI Fundamentals Exam

Correct Answer: C

Rationale: The nurse's priority should be to eliminate safety hazards from the client's environment as it directly reduces the risk of falls. Addressing environmental hazards is an immediate and crucial step in preventing falls. While completing a fall-risk assessment is important to understand the client's risk factors, educating the client and family about fall risks is essential for prevention, and ensuring the use of assistive aids is crucial for safety, eliminating safety hazards takes precedence as it directly mitigates the risk of falls.

Correct Answer: B

Rationale: The correct answer is B: Bruit. A bruit is a blowing sound indicating turbulent blood flow, often heard over the aorta. Choices A, C, and D are incorrect. A gallop is a cardiac sound resembling the sound of a galloping horse. A thrill is a vibration felt on palpation, and a murmur is a swooshing or whooshing sound heard during auscultation of the heart or blood vessels. In this scenario, the blowing sound over the aorta specifically indicates a bruit, which signifies turbulent blood flow and should be further assessed by the healthcare provider.

Correct Answer: A

Rationale: When a client is using a nasal cannula for oxygen therapy, the areas prone to skin damage are the tops of the ears and around the nostrils. The pressure exerted by the cannula on these areas can lead to skin breakdown, so it is important for the nurse to observe these sites for any signs of damage. The correct answer is 'Tops of the ears.' Choices 'Bridge of the nose' and 'Over the cheeks' are not typically areas where skin damage related to the cannula would occur, making them incorrect choices.

Correct Answer: A

Rationale: Inspection is the initial step in abdominal assessment as it allows the healthcare professional to visually observe any abnormalities or signs of bloating. Palpation, auscultation, and percussion are subsequent assessment techniques that follow inspection. Palpation involves feeling for tenderness, masses, or organ enlargement; auscultation is listening for bowel sounds; and percussion is used to assess the density of underlying tissues or detect the presence of fluid or air in the abdomen. In the context of a client reporting bloating, the first step should be visual inspection to gather initial information. Palpation, auscultation, and percussion come after inspection to provide a more comprehensive assessment.

Correct Answer: C

Rationale: The correct technique for using a flow-oriented incentive spirometer involves breathing in slowly and deeply to raise the ball or piston. This action helps to expand the lungs and improve lung function. Option A is incorrect as coughing deeply after each use is not part of using the spirometer. Option B is incorrect as holding the breath for 10 seconds is not the correct instruction for using the spirometer. Option D is incorrect as exhaling forcefully before using the spirometer is not the appropriate step in using this device.
