Question 131 pts

The nurse cares for a client diagnosed with respiratory failure. Heart rate is 124 beats per min., respiratory rate 24/min, blood pressure 168/98 mm Hg, oxygen saturation of 84% and laboratory results show a pH 7.28. The patient can be aroused, but returns to sleep quickly. High Flow Oxygen is initiated at 15 L/min. On reassessment, which findings would indicate a positive response to therapy? (Select all that apply)

Group of answer choices

The patient is somnolent.

The client's breathing requires less effort.

Blood pH is 7.26.

Oxygen saturation is 90%.

Respiratory rate is 19.

Answer 1

Respiratory failure refers to inability of the lungs to remove excess carbon dioxide from the blood and this results in hypercapnea. The low level of oxygen in the blood leads to hyperemic respiratory failure. The common etiology that results in respiratory failure are: chronic lung diseases like pneumonia,tuberculosis,chronic obstructive pulmonary disease,pulmonary embolism,cystic fibrosis these diseases affect the gas exchange and perfusion in the airs acs, nerve and muscle diseases that affect breathing,any injury to the lungs,substance abuse that depresses medulla oblongata that depresses respiration.

Low oxygen level results in lack of perfusion in the vital organs. It leads to cyanosis,shortness of breath, tachypnea and confusion. Oxygen therapy needed to meet additional demand of the lungs. High flow oxygen therapy improves the presence of oxygen in the lungs and reduces SOB there by increasing vital organs perfusion.

The patient can be aroused, but returns to sleep quickly. High Flow Oxygen is initiated at 15 L/min. On reassessment, which findings would indicate a positive response to therapy? (Select all that apply)

The correct options are :

The client's breathing requires less effort: it indicates there is lessen air hunger and there is adequate oxygen present inside the lungs for perfusion.

Oxygen saturation is 90%. It refers to percentage of oxygen saturated with hemoglobin, A marked improvement of oxygen concentration from 84% to 90% indicates adequate oxyhemoglobin.

Respiratory rate is 19. It indicates less strenous breathing.
