Explanation:
(A) High Fowler position decreases venous return to the heart and permits greater lung expansion so that oxygenation is maximized. (B) Lying on the left side may improve perfusion to the left lung but does not promote lung expansion. (C) Sitting in a chair will decrease venous return and promote maximal lung expansion. However, clients with pulmonary edema can deteriorate quickly and require intubation and mechanical ventilation. If a client is sitting in achair when this deterioration happens, it will be difficult to intervene quickly. (D) The supine with feet elevated position increases venous return and will worsen pulmonary edema.

Explanation:
(A) This answer is an incorrect application of the GTPAL method.
One prior pregnancy was a preterm birth at 36 weeks (T =1, P= 1; not T = 2). (B) This answer is an incorrect application of the GTPAL method. The client is currently pregnant for the third time (G = 3, not 2), one prior pregnancy was preterm (T= 1, P= 1; not T= 2), and she has had no prior abortions (A =0). (C) This answer is the correct application of GTPAL method. The client is currently pregnant for the third time (G =3), her first pregnancy ended at term (>37 weeks) (T = 1), her second pregnancy ended preterm 20-
33 weeks) (P = 1), she has no history of abortion (A=0), and she has two living children (L = 2). (D) This answer is an incorrect application of the GTPAL method. The client is currently pregnant for the third time (G =3, not 2).
