A nurse is obtaining a weekly weight for a client who has obesity and osteoarthritis and is on a weight management program. The nurse determines that the client gained 1.36 kg (3 lb) in the past week. Which of the following statements should the nurse make?

Choice A reason: This is a correct statement, because checking the heart rate each day can help monitor the function and effectiveness of the pacemaker, and detect any signs of malfunction, such as bradycardia, tachycardia, or irregular rhythm.

Choice B reason: This is an incorrect statement, because the client still needs to take the antihypertensive medications as prescribed, even with a pacemaker. The pacemaker regulates the heart rate, but does not control the blood pressure, which can be affected by other factors, such as stress, diet, or kidney function.

Choice C reason: This is an incorrect statement, because the client should avoid stretching the arms above the head for the first few weeks after the pacemaker insertion, as it can cause dislodgment or damage to the pacemaker leads. The client should limit the arm movements and activities until the incision site heals and the provider approves.

Choice D reason: This is an incorrect statement, because the client can stand in front of a microwave oven without any risk, as long as the oven is in good working condition and does not leak radiation. The modern microwave ovens and pacemakers are designed to prevent any interference or damage. However, the client should avoid close contact with other sources of electromagnetic fields, such as metal detectors, cell phones, or MRI machines.

Choice A reason: This is the correct information, because pursed-lip breathing can help improve gas exchange by creating positive pressure in the airways, preventing air trapping and alveolar collapse, and increasing the exhalation time.

Choice B reason: This is an incorrect information, because limiting fluid intake to 1,500 ml per day can cause dehydration and thickening of the respiratory secretions, which can impair gas exchange and increase the risk of infection.

Choice C reason: This is an incorrect information, because practicing chest breathing each day can worsen gas exchange by increasing the use of accessory muscles, decreasing the diaphragmatic excursion, and reducing the lung expansion.

Choice D reason: This is an incorrect information, because wearing home oxygen to maintain an SpO2 of at least 94% can be harmful for a client who has emphysema, as it can suppress the hypoxic drive and cause carbon dioxide retention, which can lead to respiratory acidosis and coma. The client who has emphysema should wear home oxygen to maintain an SpO2 of 88% to 92%, or as prescribed by the provider.
