HESI Fundamentals Exam

Correct Answer: C

Rationale: Shortness of breath is the most concerning assessment finding in a client with a history of atrial fibrillation. It can indicate a worsening of the condition, pulmonary edema, or the development of a complication such as heart failure. A blood pressure of 150/90 mmHg, while elevated, is not as immediately concerning as respiratory distress in this context. An irregular heart rhythm is expected in atrial fibrillation and may not necessarily be a new or concerning finding. Fatigue is a common symptom in atrial fibrillation but is not as acutely concerning as shortness of breath, which may indicate compromised oxygenation and circulation.

Correct Answer: A

Rationale: Weight loss is a common finding in clients with hyperthyroidism due to increased metabolic activity. Hyperthyroidism leads to an overactive thyroid gland, which results in an increased metabolic rate and often leads to weight loss despite a normal or increased appetite. Cold intolerance (Choice B) is more commonly associated with hypothyroidism, where the body's processes slow down. Bradycardia (Choice C) is a slow heart rate, which is not typically seen in hyperthyroidism; rather, tachycardia or an increased heart rate is more common. Dry skin (Choice D) is also not a typical finding in hyperthyroidism, as the skin is more likely to be warm and moist due to increased metabolic activity.

Correct Answer: B

Rationale: The correct way to transcribe the dosage of three tenths of a milligram of levothyroxine IV STAT is 0.3 mg. When expressing decimals less than 1, there should be a leading zero before the decimal point. Choice A is incorrect (.3 mg) because it lacks the leading zero. Choice C (0.30 mg) is incorrect as it includes a trailing zero after the decimal point, which is unnecessary. Choice D (3/10 mg) is incorrect as it presents the dosage as a fraction, which is not the standard format for transcribing medication dosages. Therefore, B (0.3 mg) is the most appropriate and accurate way to document this prescription on the client's medical record.

Correct Answer: B

Rationale: Auscultating lung sounds is crucial for assessing the extent of congestion in a client with CHF. The presence of crackles or wheezing can indicate fluid accumulation in the lungs, a common complication of CHF. Monitoring urine output (Choice A) is important to assess renal function but is not the priority in this situation. While assessing the apical pulse (Choice C) and checking blood pressure (Choice D) are important in managing CHF, they do not provide immediate information about the respiratory status and congestion level in the lungs, making auscultating lung sounds the most critical 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.
