(A)Oxytocin may not be necessary if the bladder is emptied and if the uterus remains firm, midline, and at about U11 after massage. (B) The same rationale as for answer "A" applies.
(C)A full bladder is the most common cause of uterine atony. If the bladder is full, it should be emptied and the uterus reassessed before further intervention. (D) If the bladder is full, the uteruswill not stay contracted or return to a normal position. Overly vigorous massage also encourages uterine atony.

Explanation/Reference:
Explanation:
(A) Maintaining bed rest helps to decrease the O2 needs of the tissues, which decreases dyspnea and workload on the respiratory system. (B) The semi-Fowler or high-Fowler position is necessary to aid in lessening pressure on the diaphragm from the abdominal organs, which facilitates comfort and easier breathing patterns. (C) Cerebral hypoxia causes the client with pneumonia to be increasingly irritable and restless and results from the client not obtaining enough O2 to meet metabolic needs. (D) Proper hydration facilitates liquefaction of mucus trapped in the bronchioles and alveoli and enhances expectoration. Unless contraindicated, a reasonable amount of IV fluids to be administered is at least 2.5-3 liters in a 24-hour period.

(A) Hematomas, which are the result of damage to a vessel wall without laceration of the
tissue, are a cause, though not the most frequent cause. (B) Coagulation disorders are among the causes of postpartal hemorrhage, but they are less common. (C) The most frequent causes of hemorrhage in the postpartal period are related to an interference with involution of the uterus. Uterine atony is the most frequent cause, occurring in the first 24 hours after delivery. (D) Retained placental fragments are also a cause, although these bleeds usually occur 7-14 days after delivery.

Explanation
(A) Bright red sputum with streaks is associated with pneumonia caused by gram-negative bacteria, such asKlebsiellapneumonia. (B) Pneumococcal pneumonia, caused by gram-positive bacteria, has a characteristic productive cough with green or rust-colored sputum. (C) Green-colored sputum is more characteristic ofPseudomonasthan of gram-positive bacterial pneumonia. (D) Pink-tinged and frothy sputum is more characteristic of pulmonary edema than of gram-positive bacterial pneumonia.

Explanation
(A) This response uses the principle of reality orientation by the nurse telling the client that he or she does not see anything, but it does recognize his feelings. (B) This response does not make it clear that the nurse does not see anyone else in the room, and the nurse leaves the client alone to continue hallucinating. (C) This response leaves room for doubt; the nurse is further confusing the client by this statement. (D) This response reinforces the hallucination and implies that the nurse sees his mother, too.
