Explanation:
(A) This statement is entirely false. (B) Phantom pain may be caused by nerves continuing to carry sensation to the brain even though the limb is removed. It is real, intense, and should be treated as ordinary pain would. (C) Although the cause of phantom pain is still unknown, thesemeasures may promote the relief of any type of pain, not just phantom pain. (D) Phantom pain is not caused by trauma, spasms, and edema and will not be relieved by decreasing edema.

Explanation
(A) Respiratory acidosis is the result of problematic ventilation. Plasma pH decreases, while plasma PCO2 and plasma HCO3 increase. (B) Respiratory alkalosis results from increased respiratory rate and depth. Plasma pH increases, while plasma PCO2 and plasma HCO3 decrease. (C) Metabolic acidosis occurs when there is strong acid gain in the body. Plasma pH, PCO2, and HCO3 decrease. (D) Increased risk for metabolic alkalosis is due to a loss of hydrogen ions; depletion of potassium, sodium, and chloride when vomiting occurs. Plasma pH and plasma PCO2 increase; plasma HCO3 may decrease and then increase to compensate.

(A) With the slight and mild hard of hearing, auditory training is beneficial. (B) Speech is the most difficult task because it is learned by visual and auditory stimulation, imitation, and reinforcement. (C, D) Lip reading and signing are aimed at establishing communicative skills, but they are learned more easily by visual stimulation.

Explanation:
(A) Anemia and vomiting are not cardinal signs of diabetes insipidus. (B) Polyuria and polydipsia are the cardinal signs of diabetes insipidus. (C) Irritability relieved by feeding water, not formula, is a common sign, but not the cardinal sign, of diabetes insipidus. (D) Hypothermia and azotemia are signs, but not cardinal signs, of diabetes insipidus.

Section: Questions Set D
Explanation:
(A) The refrigerated cool mist tent creates a cool, moist environment. The child as well as bedding and clothing may become dampened. Monitoring the temperature of the child will ensure warmth and prevent chilling. (B) Only a low-grade fever is expected in laryngotracheobronchitis. (C) Febrile seizures are not expected with the low-grade fever. (D) Inflammation of the mucosal lining in the respiratory tract can cause airway obstruction.
However, monitoring the child's temperature would not prevent airway obstruction.
