Which assessment finding for a patient receiving IV furosemide(Lasix) to treat stage 2 hypertension is most important to report to the health care provider?

Correct Answer: B

Rationale: Hypokalemia is a frequent adverse effect of the loop diuretics and can cause life-threatening dysrhythmias. The health care provider should be notified of the potassium level immediately and administration of potassium supplements initiated. The elevated blood glucose and BP also need collaborative intervention but will not require action as urgently as the hypokalemia. An orthostatic drop of 12 mm Hg will require intervention only if the patient is symptomatic.

Correct Answer: A

Rationale: The most appropriate expected outcome for a patient who is given the nursing diagnosis of risk for ineffective health maintenance is that he or she takes the medication as prescribed. The other listed goals are valid aspects of care, but none directly relates to the patient's role in his or her treatment regimen.

Correct Answer: D

Rationale: Hypertension often accompanies other risk factors for atherosclerotic heart disease, such as dyslipidemia (abnormal blood fat levels), obesity, diabetes, metabolic syndrome, and a sedentary lifestyle. Individuals with hypertension need to monitor their sodium intake, but hypernatremia is not a risk factor for hypertension. In many patients, heart rate does not correlate closely with BP. Potassium levels do not normally relate to BP.

Correct Answer: D

Rationale: During intense exercise, oxygen consumption of skeletal muscles can increase up to 100-fold.

Correct Answer: C

Rationale: The aorta wall is approximately 1 mm thick.
