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: 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: During a standing assessment, the healthcare professional should observe the patient laterally. In a normal body alignment, the head is erect, and the spinal curves align in a reversed 'S' pattern, aiding in maintaining balance and posture. Choice B is incorrect because hips and shoulders should be level and not form an 'S' pattern when observed posteriorly. Choice C is incorrect as the position of the arms is not a key indicator of body alignment. Choice D is incorrect as the feet should be shoulder-width apart with toes pointing forward for optimal balance and stability.

Correct Answer: D

Rationale: Crackles in the lungs are concerning because they indicate pulmonary congestion, a serious complication of congestive heart failure. The presence of crackles suggests fluid accumulation in the lungs, requiring immediate attention to prevent respiratory distress and worsening heart failure. While shortness of breath on exertion, weight gain, and orthopnea are common signs and symptoms of heart failure, crackles specifically point to acute pulmonary edema or worsening congestion, making them the most concerning finding in this scenario.

Correct Answer: A

Rationale: Pharyngeal diphtheria is transmitted via droplets, primarily through respiratory secretions. Therefore, droplet precautions are necessary to prevent the spread of the infection. Droplet precautions involve wearing a surgical mask, goggles, and a gown when within three feet of the client. Contact precautions are used for diseases transmitted by direct or indirect contact; airborne precautions are for diseases transmitted through airborne particles; protective precautions are not a standard precaution type.
