Correct Answer: B

Rationale: During pregnancy, weight gain is expected. The client's understanding is demonstrated by acknowledging the need for alternative sexual positions due to the physiological changes, such as weight gain and a growing abdomen. This statement reflects comprehension of the teaching provided by the healthcare provider.

Correct Answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

Correct Answer: C

Rationale: The nurse should assist the client into the hands and knees position during contractions to help relieve her back pain and facilitate the rotation of the fetus from the posterior to an anterior occiput position. This position can aid in optimal fetal positioning for delivery. Choice A, performing effleurage, is a massage technique that may provide comfort but does not address the fetal position. Placing the client in lithotomy position (Choice B) may not be ideal for a client experiencing back pain due to the occiput posterior position. Applying a scalp electrode to the fetus (Choice D) is not indicated solely for addressing the client's back pain.

Correct Answer: B

Rationale: When a newborn is transferred to the nursery, the first action the nurse should take is to verify the newborn's identification. This step is crucial for ensuring the correct care is provided to the right newborn, promoting patient safety and preventing errors. Administering vitamin K (Choice C) is important but should not be the first action. Determining obstetrical risk factors (Choice D) is not the priority when the newborn is transferred to the nursery. Confirming (Choice A) and verifying (Choice B) have similar meanings, but 'verify' is a more appropriate term in this context.

Correct Answer: D

Rationale: After an amniocentesis, the priority nursing intervention is to monitor the fetal heart rate (FHR) as the greatest risk to the client and fetus is fetal death. This monitoring helps in early identification of any fetal distress or compromise, allowing prompt intervention to ensure fetal well-being. Checking the client's temperature (Choice A) is not the priority as monitoring the fetus is crucial for immediate assessment. Observing for uterine contractions (Choice B) is important but not the priority after an amniocentesis. Administering Rho(D) immune globulin (Choice C) is typically done to Rh-negative clients after procedures that may lead to fetal-maternal hemorrhage, not immediately after an amniocentesis.
