Explanation
(A) This change in blood pressure may not be significant and does not indicate a widening pulse pressure, a late sign of increased ICP. It is important to continue to monitor for change in blood pressure. (B) Acetaminophen may be ineffective in relieving headache after head injury. Stronger analgesics are contraindicated because they mask neurological signs and may depress the CNS. (C) Pulse rates between 68 bpm and 76 bpm are within normal limits for a 14-year-old child. It is important to monitor for a consistent drop in pulse rate, which is a late sign of increasing ICP. (D) An elevated temperature is abnormal and requires further assessment and medical intervention. The temperature may be unrelated to the head injury, but CNS infection is serious and difficult to control.

Explanation:
(A) Warm, moist heat will promote circulation and provide comfort. A sitz bath should be tried before medication is given. (B) Pain medication can be given when other comfort measures such as a sitz bath and topical applications are ineffective. (C) Kegel exercises facilitate sitting by decreasing tension on the episiotomy. They will not be effective for pain control or sustained comfort level. (D) Ice packs are appropriate to apply in the first 12 hours postdelivery to produce vasoconstriction and to reduce edema to the area.

(A) With a pneumothorax, air occupies the pleural space. Crackles or rales are heard with increased fluid or secretions and would not be present with air in the space. (B) With a pneumothorax, the client would experience tachypnea and tachycardia to compensate for the decrease in oxygenation. (C) Symptoms of pneumothorax include shortness of breath, sharp pain on the affected side with movement or coughing, asymmetrical chest expansion, and diminished or absent breath sounds on the affected side. (D) With a pneumothorax, breath sounds would be decreased on the affected side (indicates air in the pleural space).

(A) This activity is too competitive, and the manic client might become abusive toward the other clients. (B) During mania, the client's attention span is too short to accomplish this task. (C) This activity uses gross motor skills, eases tension, and expands excess energy. A staff member is better equipped to interact therapeutically with clients. (D) This activity requires the use of fine motor skills and is very tedious.

Explanation
(A) This time is incorrect because regular insulin would peak after the teenager has eaten breakfast. (B) This time is incorrect because it is after lunch when the NPH peaks. (C) Regular insulin peaks in 2-3 hours and has a duration of 4-6 hours. NPH insulin's onset is 4-6 hours and peaks in 8-16 hours. Blood sugar would peak after meals and be lowest before meals and during the night. (D) This time is incorrect because it is before the NPH and after the regular insulin peak times.
