A nurse in a long-term care facility is collecting data from an older adult client. Which of the following findings indicates that the client might be dehydrated?

Choice A reason: Delaying ambulation until the next day is not an appropriate intervention, as it can cause stiffness, muscle weakness, or joint contractures in the affected knee. The nurse should encourage regular exercise and activity within the client's tolerance level to maintain joint mobility and function.

Choice B reason: Applying moist heat prior to ambulation is an appropriate intervention, as it can reduce pain and inflammation in the affected knee by increasing blood flow and relaxing the muscles and tendons around the joint.

Choice C reason: Using a continuous passive motion machine is not an appropriate intervention for osteoarthritis, as it is mainly used after knee replacement surgery to prevent scar tissue formation and improve range of motion in the new joint.

Choice D reason: Restricting intake of dairy products is not an appropriate intervention for osteoarthritis, as dairy products are good sources of calcium and vitamin D that can support bone health and prevent osteoporosis. The nurse should advise the client to eat a balanced diet that includes fruits, vegetables, whole grains, lean protein, and low-fat dairy products.

Choice A reason: Withholding the medication if the systolic blood pressure is less than 90 mm Hg is an appropriate action, as propranolol is a beta-blocker that can lower blood pressure and cause hypotension, which can impair tissue perfusion and cause dizziness, fainting, or shock.

Choice B reason: Requesting a dosage increase if the apical heart rate is less than 60/min is an inappropriate action, as propranolol can slow down the heart rate and cause bradycardia, which can lead to fatigue, weakness, or cardiac arrest. The nurse should monitor the apical pulse before administering propranolol and withhold it if it is less than 60/min.

Choice C reason: Informing the client to expect increased hair growth is an incorrect statement, as propranolol does not cause hypertrichosis or excessive hair growth. However, another beta-blocker, minoxidil, can cause this side effect.

Choice D reason: Administering the medication with an antacid is not an appropriate action, as antacids can interfere with the absorption of propranolol and reduce its effectiveness. The nurse should administer propranolol on an empty stomach or with food that does not contain antacids.
