Section: Questions Set G
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) This response will help to prevent the occurrence of postural hypotension, a common side effect of this drug and a common reason for falls. (B) Although walking is an excellent exercise, it is not specific to the reduction of risks associated with diuretic therapy. (C) Clients on diuretic therapy are generally taught to ensure that their fluid intake is at least 2000-3000 mL daily, unless contraindicated. (D) Aspirin is a safe drug to take along with furosemide.

Explanation/Reference:
Explanation:
(A) These signs are seen in pulmonic stenosis or in response to pulmonary congestion and edema and mitral stenosis. (B) These signs are seen primarily in mitral stenosis or as a late sign in aortic stenosis after left ventricular failure. (C) These signs are seen primarily in right-sided heart valve dysfunction. (D) Left ventricular hypertrophy occurs to increase muscle mass and overcome the stenosis; left ventricular pressures increase as left ventricular volume increases owing to insufficient emptying.

Section: Questions Set G
Explanation:
(A) Cathartic drugs promote evacuation of intestinal contents. (B) The client undergoing intestinal surgery is at increased risk for infection from large numbers of anaerobic bacteria that inhabit the intestines. Administering antibiotics prophylactically can reduce the client's risk for infection. (C) Antibiotics are indicated in the treatment of infections and have no effect on emotions. (D) Antipyretics are useful in the treatment of elevated temperatures. Antibiotics would have an effect on infection, which causes temperature elevation, but would not directly affect such an elevation.

(A) Instilling a cool solution does not significantly lower the body temperature during peritoneal dialysis. (B) Warmed solution does help dilate the peritoneal blood vessels, facilitating the exchange of fluids. (C) Warming the dialysate does not decrease the risk of peritoneal infection. Sterile technique decreases this risk. (D) Relaxing the abdominal muscles does not facilitate peritoneal dialysis.
