(A) Chorioamnionitis is an inflammation of the chorion and amnion that is generally associated with premature or prolonged rupture of membranes. (B) Postterm deliveries have not been shown to increase the risk of chorioamnionitis unless there has been prolonged rupture of membranes. (C) Pyelonephritis is a kidney infection that develops in 20%-40% of untreated maternal UTIs. (D) Maternal dehydration, though of great concern, is not related to chorioamnionitis.

Explanation
(A, B, C) Although all of the lab data are abnormal and although these values are decreased in aplastic anemia, the disorder is defined by severe deficits in red cell, white cell, and platelet counts. (D) Aplastic anemia is typically defined in terms of abnormalities of red blood cell count, usually <1 million, white cell count <2,000, and thrombocytes <20,000.

Explanation
(A) Crackles are caused by air moving through moisture in the small airways and occur with pulmonary edema. Paradoxical chest wall movement occurs with flail chest when a segment of the thorax moves outward on inspiration and inward on expiration. (B) Decreased breath sounds occur when a lung is collapsed or partially collapsed. Chest pain with movement occurs with rib fractures. (C) Rhonchi are caused by air moving through large fluid-filled airways. Frothy sputum may occur with pulmonary edema. (D) Wheezing is caused by fluid in large airways already narrowed by mucus or bronchospasm. Dry cough could indicate a cardiac problem.

(A)
The client may be anxious and hyperresponsive to stimuli but not necessarily restless.
(B)
This is not a physiological response to an elevated blood pressure in PIH. (C) The nurse must know the nursing measures that decrease the potential for convulsions. A quiet, darkened room decreases stimuli and promotes rest. (D) External stimuli might induce a convulsion but are not annoying to the client with PIH.
