Correct Answer is C

Explanation

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.

A. Oral (PO) B. Intravenous (IV) C. Intramuscular (M) D. Subcutaneous (SC)

Correct Answer is A

Explanation

A. The first-pass effect refers to the metabolism of a drug in the liver before it reaches systemic circulation. This primarily affects oral medications, as they are absorbed through the gastrointestinal tract and first pass through the liver.
B. Intravenous (IV) drugs bypass the first-pass effect as they are directly introduced into the bloodstream.
C. Intramuscular (IM) and D. Subcutaneous (SC) routes also bypass the first-pass effect since the drug enters the bloodstream without passing through the liver initially.
