Section: Questions Set D
Explanation:
(A) HIV is transmitted through unprotected sexual contact. (B) Condoms are an effective barrier to prevent HIV transmission. (C) HIV is not easily transmitted by casual contact. (D) HIV can be transmitted intrauterinely at the time of delivery, and by breast-feeding.

(A) High Fowler position decreases venous return to the heart and permits greater lung expansion so that oxygenation is maximized. (B) Lying on the left side may improve perfusion to the left lung but does not promote lung expansion. (C) Sitting in a chair will decrease venous return and promote maximal lung expansion. However, clients with pulmonary edema can deteriorate quickly and require intubation and mechanical ventilation. If a client is sitting in achair when this deterioration happens, it will be difficult to intervene quickly. (D) The supine with feet elevated position increases venous return and will worsen pulmonary edema.

Explanation/Reference:
Explanation:
(A) Bleeding, bruising, and hemorrhage may occur due to injury but are not classic signs of ischemia. (B) An increase in serum levels of creatinine, alkaline phosphatase, and aspartate transaminase is related to the disruption of muscle integrity. (C) Classic signs of ischemia related to vascular injury secondary to long bone fractures include the five "P's": pain, pallor, pulselessness, paresthesia, and paralysis. (D) Generalized swelling, pain, and diminished functional use with muscle rigidity and crepitus are common clinical manifestations of a fracture but not ischemia.

(A) Discomfort with ankle dorsiflexion is not expected with meningitis. (B) Spinal flexion, flexing the neck or the hips with legs extended, causes discomfort if the meninges are irritated. (C) Discomfort with wrist flexion is not expected with meningitis. (D) Rotating the cervical spine may cause discomfort with meningitis, but pain with flexion is more indicative of meningeal irritation.

Section: Questions Set C
Explanation:
(A) Bed rest will be ordered for 8-12 hours postprocedure. Flexing of the leg at the arterial puncture site will occur if the client gets out of bed, and this is contraindicated after arteriography. (B) The client will be able to eat as soon as he is alert enough to swallow safely and that will depend on what medications are used for sedation during the procedure. (C) Oozing at the arterial puncture site is not normal and should be closely evaluated. (D) The leg where the arterial puncture occurred must be kept straight for 8-12 hours to minimize the risk of bleeding.
