Explanation
(A) The physician should be notified as problems arise, but in this case, the nurse can attempt to irrigate the Foley catheter first and call the physician if irrigation is unsuccessful. Notifying the physician of problems is a subsequent nursing intervention. (B) This answer is correct. Assessing catheter patency and irrigating as prescribed are the initial priorities to maintain continuous bladder irrigation. Manual irrigation will dislodge blood clots that have blocked the catheter and prevent problems of bladder distention, pain, and possibly fresh bleeding. (C) The Foley catheter would not be changed as an initial nursing intervention, but irrigation of the catheter should be done as ordered to dislodge clots that interfere with patency. (D) Even though the client complains of increasing suprapubic pain, administration of a prescribed narcotic analgesic is not the initial priority. The effect of the medication may mask the symptoms of a distended bladder and lead to more serious complications.

(A, B, D) Intermediate-acting and long-acting preparations contain materials that increase length of absorption time from the subcutaneous tissues but cause the preparation to be cloudy and unsuitable for IV use. Human insulin must be given SC. (C) Only regular insulin can be given IV.

Explanation
(A) Tubular support, such as that received with a Jobst garment, applies tension of 10-20 mm Hg. This amount of uniform pressure is necessary to prevent or reduce hypertrophic scarring. Clients typically wear a pressure garment for 6-12 months during the recovery phase of their care. (B) Pressure garments have no ambulatory assistive properties. (C) Pressure garments can worsen the psychological impact of burn injury, especially if worn on the face. (D) Pressure garments do not normalize fluid status.

(A) Local anesthetics do temporarily relieve the pain but leave an unpleasant taste and numb feeling that are not conductive to eating. (B) Such a diet is less irritating to the damaged mucosa and is easier for the child to tolerate. (C) This intervention is helpful if the child has only anorexia. It does not work if the type and texture of the food increase oral discomfort. (D) Lemon glycerin swabs and milk of magnesia dry the oral mucosa and should be avoided.

Explanation:
(A, B, C) Clinical manifestations of right-sided heart failure are weakness, peripheral edema, jugular venous distention, hepatomegaly, jaundice, and elevated central venous pressure. (D) Clinical manifestations of left- sided heart failure are left ventricular dysfunction, decreased cardiac output, hypotension, and the backward failure as a result of increased left atrium and pulmonary artery pressures, pulmonary edema, and rales.
