Correct Answer: B

Rationale: Nagele's rule is a method used to estimate the date of delivery for pregnant clients. The rule involves subtracting 3 months and adding 7 days to the date of the first day of the last normal menstrual period, then adjusting the year. Subtracting 3 months from August 30, 2013, brings the date to May 30, 2013; adding 7 days results in June 6, 2013. Finally, after correcting the year, the estimated date of delivery is June 6, 2014. Therefore, the correct answer is June 6, 2014. Choices A, C, and D are incorrect because they do not follow the accurate calculation based on Nagele's rule.

Correct Answer: C

Rationale: The most common indication for amniocentesis in the third trimester is the determination of fetal lung maturity. This assessment is essential to evaluate the fetus's readiness for extrauterine life. Checking for alpha-fetoprotein (AFP) in the amniotic fluid is more commonly associated with midtrimester amniocentesis to identify chromosomal abnormalities. Assessing for intrauterine infection is not a primary reason for amniocentesis in the third trimester. While checking fetal cells for chromosomal abnormalities is a common indication for midtrimester amniocentesis, it is not the most common indication in the third trimester.

Correct Answer: B

Rationale: After circumcision, a yellow crust may form over the circumcision site, which is a normal part of healing and should not be removed. The mother should be reassured that this crust is to be expected. Yellow crusting or discharge is not indicative of an infection, and there is no need to notify the pediatrician. Checking the infant's temperature every 2 hours is unnecessary and may cause unnecessary alarm to the mother.

Correct Answer: D

Rationale: To test the cochlear portion of the acoustic nerve (cranial nerve VIII), the nurse should have the client close their eyes and indicate when a ticking watch is heard as the nurse moves the watch closer to the client's ear. This action assesses the client's ability to perceive auditory stimuli, as the cochlear portion of the acoustic nerve is responsible for hearing. Choices A, B, and C are incorrect. Asking the client to raise their eyebrows to check for symmetry is a method to test the facial nerve (cranial nerve VII). Asking the client to clench their teeth and palpating the masseter muscles tests the motor component of the trigeminal nerve. Having the client identify light and sharp touch on both sides of the face is a way to test the sensory component of the trigeminal nerve (cranial nerve V).

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.
