1. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

2. During a well-child visit for their child, one of the parents with an autosomal dominant disorder tells the nurse, 'We don’t plan on having any more children, since the next child is likely to inherit this disorder.' How should the nurse respond?

• A. Explain that the risk of inheriting the disorder decreases by 50% with each child the couple has.
• B. Acknowledge that the next child will inherit the disorder since the first child did not.
• C. Encourage the couple to reconsider their decision since the inheritance pattern may be sex-linked.
• D. Confirm that there is a 50% chance of their future children inheriting the disorder.

Correct answer: D

Rationale: Confirming that there is a 50% chance of their future children inheriting the disorder is the correct response in this situation. Autosomal dominant disorders have a 50% chance of being passed on to each child. Providing accurate genetic counseling is essential to help the parents make informed decisions about family planning. Choices A, B, and C are incorrect. Choice A is inaccurate because the risk of inheriting an autosomal dominant disorder remains at 50% for each child regardless of the number of children the couple has. Choice B is not appropriate as it does not provide helpful information or support to the parents. Choice C is misleading because autosomal dominant disorders follow a specific inheritance pattern and are not sex-linked.

3. A 38-week primigravida who works at a desk job and sits at a computer for 8 hours each day tells the nurse that her feet have begun to swell. Which instruction would be most effective in preventing pooling of blood in the lower extremities?

• A. Wear support stockings.
• B. Reduce salt in her diet.
• C. Move about every hour.
• D. Avoid constrictive clothing.

Correct answer: C

Rationale: During pregnancy, especially in the third trimester, it is common for women to experience swelling due to decreased circulation. Encouraging the patient to move about every hour helps prevent blood pooling in the lower extremities by promoting circulation. This simple activity can help alleviate swelling and discomfort associated with prolonged sitting.

4. An expectant father tells the LPN/LVN he fears that his wife 'is losing her mind.' He states she is constantly rubbing her abdomen and talking to the baby, and that she actually reprimands the baby when it moves too much. What recommendation should the nurse make to this expectant father?

• A. Reassure him that these are normal reactions to pregnancy and suggest that he discuss his concerns with the childbirth education nurse.
• B. Help him understand that his wife is experiencing normal maternal behaviors and bonding with the baby, and reassure him that these actions are positive.
• C. Ask him to observe his wife's behavior carefully for the next few weeks and report any similar behavior to the nurse at the next prenatal visit.
• D. Let him know that these behaviors are part of normal maternal-fetal bonding which occur once the mother feels fetal movement.

Correct answer: D

Rationale: The father's concerns about his wife's behaviors can be addressed by explaining that behaviors like talking to the baby and responding to fetal movements are part of normal maternal-fetal bonding. These actions indicate that the mother is connecting with the baby and are positive signs of a healthy pregnancy. The nurse should reassure the father that these behaviors are common and beneficial for the mother-baby relationship during pregnancy.

5. A laboring client’s membranes rupture spontaneously. The nurse notices that the amniotic fluid is greenish-brown. What intervention should the nurse implement first?

• A. Turn the client to her left side
• B. Contact the healthcare provider
• C. Assess the fetal heart rate
• D. Check the cervical dilation

Correct answer: C

Rationale: The correct answer is to assess the fetal heart rate. When amniotic fluid is greenish-brown, it may indicate the presence of meconium, which can be concerning as it may lead to fetal distress. Assessing the fetal heart rate will help determine the well-being of the fetus and guide further actions to ensure the safety of both the mother and the baby.
