Correct Answer: B

Rationale: The Apgar score is a method for rapidly evaluating an infant's cardiorespiratory adaptation after birth. The nurse assigns scores in five areas: heart rate, respiratory effort, muscle tone, reflex response, and color, totaling the scores. A score of 8 to 10 requires no action other than supporting the infant's spontaneous efforts and observation. A score of 4 to 7 indicates the need to gently stimulate the infant by rubbing his back while administering oxygen. If the score is 1 to 3, the infant requires resuscitation. Therefore, in this scenario with an Apgar score of 6, the correct action is to gently stimulate the infant by rubbing his back while administering oxygen. Initiating cardiopulmonary resuscitation would be excessive at this point, and rechecking the score in 5 minutes may delay necessary interventions. Providing no action except to support the infant's spontaneous efforts is insufficient for a score of 6, indicating the need for stimulation and oxygen administration.

Correct Answer: B

Rationale: Some studies have shown that ginseng enhances in vitro sperm motility, making Choice B the correct response. It directly addresses the client's comments about taking ginseng and provides valuable information regarding its potential effect on sperm motility. Alternative therapies are often sought by couples struggling with infertility, and acknowledging the potential benefits of ginseng can empower the client. Choice A is incorrect as it slightly misrepresents the evidence by overgeneralizing its effectiveness. Choice C dismisses ginseng without acknowledging its potential benefits, potentially closing off a fruitful discussion with the client. Choice D, while neutral, misses the opportunity to validate the client's choice and explore further options collaboratively. It is crucial for nurses to respect clients' choices, provide accurate information, and guide them effectively in exploring different alternatives.

Correct Answer: B

Rationale: The correct answer is that the client may need to drink fluids before the test and may not void until the test has been completed. For a transabdominal ultrasound, the woman is positioned on her back with her head elevated and turned slightly to one side to prevent supine hypotension. A wedge or rolled blanket is placed under one hip to help her maintain this position comfortably. If a full bladder is necessary, the woman is instructed to drink several glasses of clear fluid 1 hour before the test and told that she should not void until the test has been completed. Warm mineral oil or transmission gel is spread over her abdomen, and the sonographer slowly moves a transducer over the abdomen to obtain a picture. The procedure typically takes 10 to 30 minutes, making choice A incorrect. Choice C is incorrect because a probe is not inserted into the vagina for a transabdominal ultrasound. Choice D is incorrect because the woman is positioned on her back with her head elevated and turned slightly to one side, not specifically on her back.

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.

Correct Answer: A

Rationale: A hepatitis B screen is performed to identify antigens in maternal blood. If antigens are present, it indicates that the mother is a carrier, and the newborn will need to receive hepatitis immune globulin and vaccine soon after birth to prevent transmission. Therefore, choice A is correct. Choices B and C are incorrect because the presence of antigens indicates a positive result, not a negative one or the absence of hepatitis B in the mother. Choice D is incorrect as it suggests the client needs to receive the hepatitis B series of vaccines, which is not the immediate action required when antigens are found in the maternal blood.
