Question:

A physician orders 40 mg of lisinopril for a hypertensive patient. The floor stock lisinopril is tablets that are 20 mg each. How many tablets of lisinopril should the nurse administer?

Answer:

D / H x Q = X D (desired DOSE) / H (strength on HAND) x Q (Quantity) = X (unknown quantity) 40 / 20 x 1 = X 2 x 1 = 2 Therefore, to provide the ordered 40 mg of lisinopril, the nurse should administer (2) 20 mg tablets.

Answer:

SBAR communication is an organized way to present information quickly and completely. SBAR stands for situation, background, assessment, and recommendation. SBAR is an excellent method for nurses to communicate changes in patient condition to physicians or other providers and facilitate intervention. S: "I am concerned about Mr. J's breathing." B: "Mr. J's breathing has become more labored this shift." A: "At the beginning of the shift, Mr. J's respiratory rate was 12, his respirations were even and unlabored and his breath sounds were clear to auscultation. Now, his respiratory rate is 28, his breaths shallow with poor chest rise, and wheezing is present in all lung fields." R: "I believe Mr. J needs oxygen and a STAT breathing treatment."

Question:

How does the human diaphragm function with relation to breathing?

Inactive
Kim C.
Answer:

The diaphragm is a dome-shaped muscle at the bottom of the lungs. It separates the chest cavity from the abdominal cavity and is the primary muscle of respiration (breathing). At rest, the diaphragm is convex, or dome-shaped. When the diaphragm contracts--or moves downward away from the lungs--it becomes concave or U-shaped. This creates a vacuum inside the chest cavity that results in inspiration (breathing in) through the mouth and/or nose. At the the end of inspiration, the diaphragm relaxes and returns to its dome shape which pushes air back out of the lungs through the mouth and/or nose. This is expiration (breathing out).
