The patient inhales and exhales quickly through pursed lips.

The patient inhales deeply through the nose and exhales quickly through pursed lips.

The patient inhales deeply through the nose and exhales slowly through pursed lips.

The patient inhales deeply through pursed lips and exhales quickly through the nose.

Answer and Explanation

The Correct Answer is C

A. Inhaling and exhaling quickly through pursed lips does not achieve the intended purpose of pursed-lip breathing. This technique is designed to promote slower, controlled breathing to prevent airway collapse and improve oxygen exchange.

B. Exhaling quickly through pursed lips negates the benefits of pursed-lip breathing. The purpose of this technique is to prolong exhalation, reducing air trapping and improving ventilation.

C. Inhaling deeply through the nose and exhaling slowly through pursed lips is the correct technique for pursed-lip breathing. This method helps maintain open airways, reduces dyspnea, and promotes relaxation.

D. Inhaling deeply through pursed lips and exhaling quickly through the nose is not consistent with proper pursed-lip breathing. The inhalation should be through the nose, and exhalation should be slow and controlled through pursed lips.

Correct Answer is C

Explanation

Explanation

A. Urinary output of 80 mL/hour is not concerning and indicates adequate renal function.
B. Urinary output of 12 mL/hour is very low and may indicate renal insufficiency or dehydration, requiring immediate intervention.
C. A blood potassium level of 2.5 mEq/L is critically low and requires discontinuation of the diuretic to prevent life-threatening arrhythmias.
D. A blood potassium level of 2.9 mEq/L is also low and would be concerning, though not as critical as
2.5 mEq/L. It may still necessitate withholding the medication and addressing electrolyte imbalances.
