A nurse is reinforcing teaching with a client who is scheduled for a thallium scan. When talking with the client about this procedure, which of the following statements should the nurse give?

Choice A reason: Resting before meals helps reduce fatigue and ensures that the client has the energy to eat, which is important for maintaining nutrition in COPD patients.

Choice B reason: The correct answer is b because drinking plenty of beverages with meals can cause the client to feel full too quickly, reducing their intake of nutrient-dense foods. It is better to drink fluids between meals to ensure adequate nutrition.

Choice C reason: Eating five or six small meals each day helps prevent overeating and reduces the work of breathing, making it easier for COPD clients to maintain adequate nutrition without feeling overly full or short of breath.

Choice D reason: Increasing protein intake is important for COPD clients to maintain muscle mass and strength, which are crucial for respiratory function and overall health.

Choice A reason: An apical pulse rate different than the radial pulse rate is known as a pulse deficit, which can indicate atrial fibrillation or other cardiac arrhythmias, but it is not related to paradoxical blood pressure or constrictive pericarditis.

Choice B reason: An increase in heart rate by 20% when standing is indicative of orthostatic hypotension, not paradoxical blood pressure. This condition involves a drop in blood pressure upon standing, leading to a compensatory increase in heart rate.

Choice C reason: A drop in systolic BP by 20 mm Hg when moving from a lying to a sitting position is another indicator of orthostatic hypotension, not paradoxical blood pressure.

Choice D reason: The correct answer is d because a drop in systolic BP of more than 10 mm Hg on inspiration, known as pulsus paradoxus, is a characteristic finding in constrictive pericarditis. This occurs due to the impaired filling of the heart during inspiration, leading to a significant drop in systolic blood pressure.
