When initiating oxygen per mask to a client who is short of breath, the nurse hears a loud hissing sound after inserting the flowmeter into the wall outlet. Which should the nurse do next?

Assess the position of the mask on the client's face.

Release and reinsert the flowmeter in the wall outlet.

Attach the flowmeter to a humidification canister.

Adjust the flow rate to the prescribed liters per minute.

Answer and Explanation

The Correct Answer is B

Choice A reason: Assessing the position of the mask on the client's face is not the priority action. The mask may be well-fitted, but the oxygen delivery may be compromised by the faulty connection of the flowmeter.

Choice B reason: Releasing and reinserting the flowmeter in the wall outlet is the best action as it may correct the problem of the loose or misaligned connection. The nurse should ensure that the flowmeter is securely attached and that the oxygen is flowing properly.

Choice C reason: Attaching the flowmeter to a humidification canister is not necessary for oxygen delivery per mask. Humidification is usually added for high-flow oxygen devices such as nasal cannula or face tent.

Choice D reason: Adjusting the flow rate to the prescribed liters per minute is not the appropriate action. The flow rate may be correct, but the oxygen delivery may be impaired by the hissing sound indicating a leak or obstruction.

Correct Answer is A

Explanation

Choice A reason: Smoking cessation is the most important lifestyle modification for the nurse to encourage. Smoking is a major risk factor for cardiac disease, as it increases blood pressure, heart rate, and oxygen demand, and damages the blood vessels and the heart muscle. Quitting smoking can reduce the risk of cardiac disease by 50% within one year.

Choice B reason: Regular exercise is a beneficial lifestyle modification for the nurse to encourage, but not the most important one. Exercise can improve cardiovascular fitness, lower blood pressure, and reduce body weight, but it does not eliminate the harmful effects of smoking on the heart and blood vessels.

Choice C reason: A low-fat diet is a helpful lifestyle modification for the nurse to encourage, but not the most important one. A low-fat diet can lower cholesterol levels and prevent atherosclerosis, but it does not reverse the damage caused by smoking to the heart and blood vessels.

Choice D reason: Stress reduction is a useful lifestyle modification for the nurse to encourage, but not the most important one. Stress can trigger the release of hormones that increase blood pressure, heart rate, and oxygen demand, and can also lead to unhealthy behaviors such as smoking, overeating, and alcohol abuse. However, stress reduction alone does not address the direct effects of smoking on the heart and blood vessels.

A. Remove the basin of water from the client's bed immediately. B. Add skin cream to the basin of water while the foot is soaking. C. Remind the UAP to dry between the client's toes completely. D. Advise the UAP that this procedure is damaging to the skin.

Correct Answer is A

Explanation

Choice A reason: This is the correct action as it prevents the risk of spillage, scalding, or infection. The basin of water should not be placed on the bed, but on a bedside table or stand. The nurse should also check the temperature of the water and the condition of the client's foot.

Choice B reason: This is an incorrect action as it may cause irritation or allergic reaction. The skin cream should not be added to the basin of water, but applied after the foot is dried and inspected. The nurse should also verify the type and amount of skin cream to be used.

Choice C reason: This is an important action, but not the priority. The UAP should dry between the client's toes completely to prevent fungal growth or maceration. The nurse should also monitor the UAP's technique and provide feedback.

Choice D reason: This is an inaccurate statement. The procedure of soaking the client's foot in a basin of warm water is not damaging to the skin, if done properly and safely. The nurse should explain the rationale and benefits of the procedure to the UAP.
