(A) An anticonvulsant effect is the goal of drug therapy for PIH. However, we would not
want to increase the vasoconstriction that is already present. This would make the symptoms more severe. (B) An anticon-vulsant effect and vasodilation are the desired outcomes when administering this drug. (C) An anticonvulsant effect is the goal of drug therapy for PIH; however, hypertensive drugs would increase the blood pressure even more. (D) An anticonvulsant effect is the goal of drug therapy for PIH. MgSO4is not classified as an antiemetic. Antiemetics are not indicated for PIH treatment.

(A) These changes are common characteristics of dementia. (B) Parkinson's disease affects the muscular system. Progressive memory changes are not presenting symptoms.

Explanation/Reference:
Explanation:
(A) This is the correct method of teaching diaphragmatic breathing, which allows full lung expansion to increase oxygenation, prevent atelectasis, and move secretions up and out of the lungs to decrease risk of pneumonia. (B) Quick, short breaths do not allow for full lung expansion and movement of secretions up and out of the lungs. Quick, short breaths may lead to O2 depletion, hyperventilation, and hypoxia. (C) Expelling breaths through the nose does not allow for full lung expansion and the use of diaphragmatic muscles to assist in moving secretions up and out of the lungs. (D) Inhaling and exhaling at a rate of 20-24 times/min does not allow time for full lung expansion to increase oxygenation. This would most likely lead to O2 depletion and hypoxia.

(A) Polymerase chain reaction is the laboratory technique specific for Lyme disease. (B) Heterophil antibody test is used to diagnose mononucleosis. (C) Lyme disease does not decrease the serum calcium level. (D) Lyme disease does not increase the serum potassium level.

(A) Tetracycline should be avoided during tooth development because it interferes with enamel formation and dental pigmentation. (B) Milk interferes with the absorption of tetracyclines. (C) Children older than 9 years or past the tooth development stage may be given tetracycline.
