A nasogastric (NG) tube inserted preoperatively is attached to low, intermittent suctions. A client with an NG tube exhibits these symptoms: He is restless; serum electrolytes are Na 138, K 4.0, blood pH 7.53. This client is most likely experiencing:

  1. Hyperkalemia
  2. Hyponatremia
  3. Metabolic acidosis
  4. Metabolic alkalosis

Answer(s): D

Explanation:

(A) Sodium level is within normal limits. (B) Sodium level is within normal limits. (C) pH level is consistent with alkalosis. (D) With an NG tube attached to low, intermittent suction, acids are removed and a client will develop metabolic alkalosis.

A client with severe PIH receiving MgSO4 is placed in a quiet, darkened room. The nurse bases this action on the following understanding:

  1. The client is restless.
  2. The elevated blood pressure causes photophobia.
  3. Noise or bright lights may precipitate a convulsion.
  4. External stimuli are annoying to the client with PIH.

Answer(s): C

Explanation:

(A) The client may be anxious and hyperresponsive to stimuli but not necessarily restless. (B) This is not a physiological response to an elevated blood pressure in PIH. (C) The nurse must know the nursing measures that decrease the potential for convulsions. A quiet, darkened room decreases stimuli and promotes rest. (D) External stimuli might induce a convulsion but are not annoying to the client with PIH.
