Correct Answer: C

Rationale: The correct answer is 'Devices that apply pressure alone are available over the counter.' Acupressure over the Neiguan acupuncture point can be used as a complementary alternative therapy to relieve nausea during pregnancy. It can be performed with devices that apply pressure alone, which are available over the counter. Acupressure devices that apply electrical impulses over this point require a prescription. It is not safe to try any type of complementary alternative therapy during pregnancy, as some may be harmful to the mother and fetus. Therefore, the nurse should instruct the client about the availability of over-the-counter pressure devices for acupressure, which are generally safe to use.

Correct Answer: C

Rationale: After delivery, bradycardia (pulse rate 50-70 beats/min) may occur, reflecting the large amount of blood returning to the central circulation after delivery of the placenta. The increase in central circulation results in increased stroke volume, allowing a slower heart rate to provide adequate maternal circulation. A pulse rate of 55 beats/min falls within the normal range post-delivery, so there is no need to notify the healthcare provider immediately. It is important for the client to remain on bed rest in the immediate postpartum period to prevent complications. While range-of-motion exercises are beneficial for a client on bed rest, it is not the priority based on the data provided. Therefore, the most appropriate nursing action is to document the finding for accurate record-keeping and monitoring of the client's condition.

Correct Answer: C

Rationale: The correct answer is 'One-half.' According to the MyPlate food plan, at least half of the grains consumed daily should be whole grains. This ensures a well-balanced and healthy diet. Choices A, B, and D are incorrect because they do not align with the dietary recommendation provided by the MyPlate food plan. One-quarter, one-third, and two-thirds do not represent the appropriate proportion of whole grains as advised by the plan, which emphasizes the importance of including a significant portion of whole grains in one's diet.

Correct Answer: C

Rationale: During the fourth stage of labor, the woman's vital signs should be assessed every 15 minutes during the first hour. An increasing pulse rate is an early sign of excessive blood loss, as the heart beats faster to compensate for reduced blood volume. The blood pressure decreases as blood volume diminishes, but this is a later sign of hypovolemia. The most common reason for excessive postpartum bleeding is a uterus that is not firmly contracting and compressing open vessels at the placental site. Therefore, the nurse should check the client's uterine fundus for firmness, height, and positioning. Checking the uterine fundus is the priority action as it helps determine if the client is bleeding excessively. Notifying the registered nurse immediately is not necessary unless the cause of bleeding is unclear and needs further intervention. Continuing to check vital signs without addressing the potential issue will delay necessary intervention. Documenting findings is important, but not the immediate priority when faced with a potential emergency situation like postpartum hemorrhage.

Correct Answer: B

Rationale: If a woman pushes strenuously before the cervix is completely dilated, she risks injury to the cervix and the fetal head. Blowing prevents closure of the glottis and breath-holding, helping overcome the urge to push strenuously. The woman would be encouraged to blow repeatedly, using short puffs, when the urge to push is strong. This breathing technique allows for controlled exhalation and helps prevent unnecessary pushing. Cleansing breaths (deep inspiration and expiration at the beginning and end of each contraction) are encouraged during the first stage of labor to provide oxygenation and reduce myometrial hypoxia and to promote relaxation. Holding her breath and using the Valsalva maneuver (choice A) is not recommended as it can increase intra-abdominal pressure and decrease venous return, potentially compromising fetal oxygenation. Deep inspiration and expiration at the beginning and end of each contraction (choice D) are more suitable for relaxation and oxygenation purposes rather than managing the urge to push.
