A 17-year-old pregnant client who is gravida 1, para 0, is at 36 weeks' gestation. Based on the nurse's knowledge of the maternal physiological changes in pregnancy, which of these findings would be of concern?

  1. Complaints of dyspnea
  2. Edema of face and hands
  3. Pulse of 65 bpm at 8 weeks, 73 bpm at 36 weeks
  4. Hematocrit 39%

Answer(s): B

Explanation:

(A) Dyspnea is a common complaint during the third trimester owing to the increasing size of the uterus and the resulting pressure against the diaphragm. (B) Edema of the face, hands, or pitting edema after 12 hours of bed rest may be indicative of preeclampsia and would be of great concern to the healthcare provider. (C) An increase in heart rate of 10­15 bpm is a normal physiological change in pregnancy due to the multiple hemodynamic changes. (D) A hematocrit value of 39% is within the normal range. A value <35% would indicate anemia.

The physician prescribes a medical regimen of isoniazid, rifampin, and vitamin B6 for a tuberculosis client.

  3. Improves nutritional status
  4. Reduces peripheral neuropathy

Answer(s): D

Explanation:

(A) Vitamin B6does not enhance the activity of isoniazid. (B) Vitamin B6does not enhance the activity of rifampin. (C) A vitamin alone does not improve nutritional status. (D) Isoniazid leads to Vitamin B6deficiency, which is manifested as peripheral neuropathy.
