A hepatitis B screen is performed on a pregnant client, and the results indicate the presence of antigens in the client's blood. On the basis of this finding, the nurse makes which determination?
- A. Hepatitis immune globulin and vaccine will be administered to the newborn infant soon after birth
- B. The results are negative.
- C. The results indicate that the mother does not have hepatitis B
- D. The client needs to receive the hepatitis B series of vaccines.
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.

Which of the following vaccines are not part of the regular schedule of immunizations for children?

While performing a physical assessment on a 6-month-old infant, the nurse observes head lag. Which of the following nursing actions should the nurse perform first?
- A. Ask the parents to allow the infant to lie on his stomach to promote muscle development.
- B. Notify the physician because a developmental or neurological evaluation is indicated.
- C. Document the findings as abnormal in the nurse's notes.
- D. Explain to the parents that their child is likely to have developmental delays.
Correct Answer: B
Rationale: Head lag should be completely resolved by 4 months of age. Continuing head lag at 6 months of age indicates the need for further developmental or neurological evaluation. Laying the infant on his stomach promotes muscle development of the neck and shoulder muscles, but because of the age of this child, a referral should be the first action. The findings are abnormal for a 6-month-old infant. Significant head lag can be seen in infants with Down syndrome and hypoxia, as well as neurological and other metabolic disorders. While some of these disorders might include developmental delays, stating this to the parents without a proper evaluation can cause unnecessary distress. The priority is to identify the cause of the head lag through a medical evaluation before discussing potential outcomes with the parents.
A nurse demonstrates the procedure for bathing a newborn to a new mother. The next day, the nurse watches as the mother bathes the infant. The nurse determines that the mother is performing the procedure correctly if the mother performs which action?
- A. Uses a cotton-tipped swab to carefully clean inside the infant's nose
- B. Uncovers only the body part being washed
- C. Washes the diaper area first
- D. Washes the infant's chest first
Correct Answer: B
Rationale: When bathing a newborn, it is crucial to follow a specific sequence for thorough cleaning and safety. The correct sequence includes starting with the eyes and face, then moving to the external ear, areas behind the ears, neck, hands, arms, legs, and finally the diaper area. Keeping the infant warm is essential, so only the body part being washed should be uncovered. Using a cotton-tipped swab to clean inside the infant's nose is not recommended due to the risk of injury if the infant moves suddenly. Washing the diaper area first is incorrect as it should be done towards the end of the bath to prevent contamination. Washing the infant's chest first is also incorrect as it deviates from the recommended bathing sequence for a newborn.
A woman in labor whose cervix is not completely dilated is pushing strenuously during contractions. Which method of breathing should the nurse encourage the woman to perform to help her overcome the urge to push?
- A. Holding her breath and using the Valsalva maneuver
- B. Blowing repeatedly in short puffs
- C. Cleansing breaths
- D. Deep inspiration and expiration at the beginning and end, respectively, of each contraction
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.
When a client who is having trouble conceiving says to the nurse, 'I have started taking ginseng,' the best response by the nurse is:
- A. "There is some evidence that ginseng may enhance in vitro sperm motility."?
- B. "Some studies show that ginseng enhances in vitro sperm motility."?
- C. "Ginseng is not proven to be effective for infertility; have you considered other options?"?
- D. "It's probably not going to hurt you, but it's also probably not going to help. Let's look at some other alternatives."?
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.
