Explanation
(A) Vitamin B6does not enhance the activity of isoniazid. (B) Vitamin B6does not enhance the activity of rifampin. (C) A vitamin alone does not improve nutritional status. (D) Isoniazid leads to Vitamin B6deficiency, which is manifested as peripheral neuropathy.

(A)
Ice creates a dramatic temperature change in the tissue, which can cause further thermal injury. (B) Charred clothing should not be removed from wound first. This creates further tissue damage. Debridement is not the first nursing action. (C) Applying silver sulfadiazine cream first insulates heat in injured tissue and increases potential for infection.
(D)
Emergency care of a thermal burn is immersing both legs in cool water. Cool water permits gradual temperature change and prevents further thermal damage.

Explanation
(A) Suggesting that a client increase a medication dosage is an inappropriate (and illegal) nursing action. This action requires a physician's order. (B) To suggest that a client decrease a medication dosage is an inappropriate (and illegal) nursing action. This action requires a physician's order. (C) This response is an appropriate independent nursing action. Because motorrestlessness can also be a side effect of cogentin, the nurse may suggest that the client try taking the drug early in the day rather than at bedtime. (D) Certain medications can cause gastric irritation and may be taken with food or milk to prevent this side effect.

(A) Women with pregnancy-induced hypertension have a reduced plasma volume secondary to venous vessel constriction, not hypovolemia; therefore, sodium restriction is not recommended. It is suggested that these women avoid extremely salty foods. (B) Drinking six to eight glasses of water per day facilitates optimal fluid volume and renal perfusion, but it will not decrease the venous vessel constriction of pregnancy-induced hypertension. (C) Carbohydrate needs increase during pregnancy, specifically during the second and third trimesters, but they have not been linked to pregnancy-induced hypertension. (D) Loss of urinary protein (proteinuria) is associated with increased permeability of the large protein molecules with pregnancy-induced hypertension.Additional dietary protein also helps increase the plasma colloidal osmotic pressure. Diets deficient in protein have been linked to pregnancy-induced hypertension.

Explanation:
(A) The AIDS virus cannot be transmitted to the donor through the blood donation procedure. (B) The test for the AIDS virus is not absolutely foolproof; therefore, it is not wise for a person with known risk factors to donate blood. (C) It takes time for antibodies to the AIDS virus to develop. An infected individual could donate contaminated blood without it testing positive for the virus. (D) For reasons of confidentiality, information about individuals infected with AIDS is not made public.
