Fundamentals of Nursing HESI

Correct Answer: D

Rationale: During a patient assessment, critical thinking is a priority because a patient's condition can change rapidly, necessitating continuous critical thinking and adaptation of nursing interventions. While foot care, daily bathing, and hygiene needs are important components of patient care, they may not always take precedence over critical thinking, which guides the nurse in making timely and appropriate decisions based on the patient's current condition and needs. Therefore, critical thinking stands out as the most crucial principle during patient assessments.

Correct Answer: A

Rationale: The correct advice for a client feeling dizzy upon standing after taking a diuretic for hypertension is to avoid standing up too quickly. Diuretics can lead to orthostatic hypotension, causing dizziness upon sudden position changes. Increasing fluid intake can exacerbate the issue by further lowering blood pressure. Eating more salt might counteract the diuretic's effects but is not the primary intervention for orthostatic hypotension. Compression stockings are more relevant for venous insufficiency than for orthostatic hypotension.

Correct Answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

Correct Answer: A

Rationale: The correct answer is walking briskly. Weight-bearing exercises, such as brisk walking, are recommended for individuals at risk for osteoporosis because they help maintain bone mass and prevent bone loss. Riding a bicycle and performing isometric exercises are not weight-bearing activities, and therefore, may not provide the same bone-strengthening benefits as walking. High-impact aerobics can increase the risk of fractures in individuals with osteoporosis due to the high level of impact involved.

Correct Answer: D

Rationale: The correct answer is D: 'I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or other medications that increase the risk of bleeding. Choices A, B, and C are correct statements that show understanding of warfarin therapy, such as the importance of avoiding foods high in vitamin K, taking medication consistently, and using a soft toothbrush to prevent gum bleeding.
