Explanation
(A) Digoxin should not be given to adults with an apical pulse < 60 bpm. (B) Digoxin should be given to children with an apical pulse > 100 bpm. With a pulse < 100 bpm, the medication should be withheld and the physician notified. (C) Prior to digoxin administration in both children and adults, an apical pulse should be taken for 1 full minute. Aside from the rate per minute, the nurse should note any sudden increase or decrease in heart rate, irregular rhythm, or regularization of a chronic irregular heart rhythm. (D) Early indications of digoxin toxicity, such as visual disturbances, occur rarely as initial signs in children.

(A) Partial thromboplastic time measures activity of thromboplastin, which depends on the intrinsic clotting factors deficient in children who are hemophiliacs. (B) Platelet counts are normal in hemophilia. (C) Hemophilia does not affect the complete blood count. (D) Bleeding times are normal in hemophiliacs. They measure the time interval for the bleeding from small superficial wounds to cease.

Explanation
(A) There will be no need to increase fluid intake excessively, because dumping syndrome could present a problem. (B) Followup visits every 3 weeks are not a standard recommendation. Follow-up visits will be highly individualized. (C) With removal of the stomach, intrinsic factor will no longer be produced. Intrinsic factor is necessary for vitamin B12 absorption. Parenteral injections of B12 will be needed on a monthly basis for the rest of the person's life. (D) Smaller, more frequent meals, rather than large, bulky meals, are recommended to prevent problems with dumping syndrome.

Explanation:
(A) Analgesic medication does not counteract the effects of antibiotics. (B) Analgesic medication may lower blood pressure elevated due to anxiety. (C) Analgesic medication, especially CNS depressants, is not given if there is danger of increasing ICP, because neurological changes may not be apparent. Also, further depression of the CNS is contraindicated. (D) Analgesics do not stimulate the CNS.

Explanation
(A) Kussmaul's respirations are associated with diabetic ketoacidosis, severe hemorrhage, peritonitis, renal failure, and uremia. (B) Tachypnea (respiratory rate >25 breaths/min) is often associated with fever. (C) Cheyne-Stokes respiratory pattern is most often associated with increased intracranial pressure secondary to changes in pressure in the cerebral and cerebellar areas. (D) Biot's breathing is most frequently associated with spinal meningitis.
