Regular exercise.

Stress reduction.

Smoking cessation.

Low-fat diet.

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect because regular exercise is a beneficial lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a greater impact on reducing the risk of cardiovascular events and mortality.

Choice B Reason: This is incorrect because stress reduction is a helpful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a more direct effect on improving the function and structure of the blood vessels and heart.

Choice C Reason: This is correct because smoking cessation is the most important lifestyle modification for preventing and managing cardiac disease, as smoking is a major modifiable risk factor that can cause atherosclerosis, hypertension, arrhythmias, thrombosis, and myocardial infarction.

Choice D Reason: This is incorrect because a low-fat diet is a useful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a stronger influence on lowering the levels of cholesterol and inflammation in the blood.

Correct Answer is B

Explanation

Choice A Reason: This is incorrect because palpating the suprapubic region for distention can be inaccurate and unreliable, as it can be affected by factors such as obesity, abdominal muscle tone, and bowel gas.

Choice B Reason: This is correct because scanning the client's bladder after voiding can measure the post-void residual urine volume, which indicates the amount of urine left in the bladder after urination. A high post-void residual urine volume can indicate urinary retention.

Choice C Reason: This is incorrect because reviewing the chart for number of voids over last 24 hours can provide information about the frequency of urination, but not the amount or completeness of urination.

Choice D Reason: This is incorrect because evaluating the client for urinary incontinence can assess the involuntary loss of urine, but not the ability to empty the bladder completely.

A. Decrease the flow rate to 1 L/minute. B. Place padding around the cannula tubing. C. Apply lubricant to the cannula tubing. D. Discontinue the use of the nasal cannula.

Correct Answer is B

Explanation

Choice A Reason: This is incorrect because decreasing the flow rate to 1 L/minute can compromise the client's oxygenation and worsen hypoxia. The client's oxygen saturation level is below the normal range of 95% to 100%.

Choice B Reason: This is correct because placing padding around the cannula tubing can prevent pressure ulcers and skin breakdown caused by friction and irritation from the tubing.

Choice C Reason: This is incorrect because applying lubricant to the cannula tubing can increase the risk of infection and inflammation of the nasal mucosa. Lubricant should be applied sparingly to the nares only if needed.

Choice D Reason: This is incorrect because discontinuing the use of the nasal cannula can endanger the client's life and cause respiratory failure. The client needs supplemental oxygen to maintain adequate oxygenation.
