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 10-15 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.

Explanation
(A) The nurse may never discontinue a central line without a physician's order. (B) The nurse may never initiate a peripheral IV without a physician's order except in an emergency situation. (C) The nurse should always document findings and alert the physician to the findings as well. The physician may then initiate a new central line and order the current central line to be discontinued. (D) Besides cleaning and redressing, the nurse should always document the findings.

Explanation:
(A) FHT should be monitored continuously with an induction of labor; this is an accepted standard of care.
(B) The physician should be notified, but this is not the first intervention the nurse should do. (C) The standard of care for an induction according to the Association of Women's Health, Obstetric, and Neonatal Nurses and American College of Obstetrics and Gynecology is that contractions should not exceed 60 seconds in an induction. Inductions should simulate normal labor; 70-second contractions during the latent phase (3 cm) are not the norm. The next contractions can be longer and increase risks to the mother and fetus. (D) Contractions lasting 60-90 seconds during transition are typical; this provides a good distractor.
The nurse needs to be knowledgeable of the phases and stages of labor.

Section: Questions Set D
Explanation:
(A) Zinc oxide is not usually applied to inflamed areas because it contributes to sweat retention. (B) Talcum powder is of questionable benefit and poses a hazard of accidental inhalation. (C) Removing the diaper and exposing the area to air and light facilitate drying and healing. (D) Infants may be sensitive to one or more agents in the wet "wipes." It is better to simply clean with a wet cloth.

Section: Questions Set A
Explanation:
(A, B, D) These occur in both tension pneumothorax and open pneumothorax. (C) The tension pneumothorax acts like a one-way valve so that the pneumothorax increases with each breath. Eventually, it occupies enough space to shift mediastinal tissue toward the unaffected side away from the midline. Tracheal deviation, movement of point of maximum impulse, and decreased cardiac output will occur. The other three options will occur in both types of pneumothorax.
