The parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide these parents?
- A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
- B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
- C. The lack of the protein dystrophin in the mother can impact the XXX muscle groups of males.
- D. Spinal cord damage due to birth trauma during a breech vaginal birth weakens the muscles.
Correct Answer: A
Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder, meaning the gene mutation causing DMD is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if the X chromosome they inherit from their mother carries the mutated gene, they will develop DMD. Females have two X chromosomes, so they are carriers of the gene but are usually not affected by the disease. Therefore, the nurse should explain to the parents that DMD is an inherited X-linked recessive disorder that primarily affects male children in the family.

A 6-year-old with heart failure (HF) gained 2 pounds in the last 24 hours. Which intervention is more important for the nurse to implement?
- A. Graph the daily weight for the past week.
- B. Decrease IV flow rate.
- C. Assess bilateral lung sounds.
- D. Restrict intake of oral fluids.

A client who is 32 weeks' gestation comes to the women's health clinic and reports nausea and vomiting. On examination, the nurse notes that the client has an elevated blood pressure. Which action should the nurse implement next?
- A. Inspect the client's face for edema.
- B. Ascertain the frequency of headaches.
- C. Evaluate for a history of cluster headaches.
- D. Observe and time the client's contractions.
Correct Answer: A
Rationale: Inspecting the client's face for edema is crucial to assess for preeclampsia, a serious condition characterized by high blood pressure during pregnancy. Edema, particularly facial edema, can be a significant indicator of preeclampsia, prompting the need for further evaluation and management to ensure the well-being of both the client and the unborn child.
A pregnant woman in her first trimester is experiencing watery vaginal discharge. What should the nurse tell her?
- A. Inform her that it is normal.
- B. Advise her to see a doctor immediately.
- C. Suggest using panty liners.
- D. Suggest a change in diet.
Correct Answer: A
Rationale: Informing the pregnant woman that watery vaginal discharge is normal during the first trimester is crucial to providing reassurance and reducing anxiety. This discharge, known as leukorrhea, is common during pregnancy due to increased estrogen levels and increased blood flow to the pelvic area. It helps maintain a healthy balance of bacteria in the vagina and protects the birth canal from infection. Advising the woman to see a doctor immediately may cause unnecessary alarm, while suggesting the use of panty liners can help manage the discharge comfortably. Suggesting a change in diet is not relevant to addressing watery vaginal discharge in this scenario.
A client who had her first baby three months ago and is breastfeeding her infant tells the nurse that she is currently using the same diaphragm that she used before becoming pregnant. What information should the nurse provide this client?
- A. Use an alternative form of contraception until a new diaphragm is obtained.
- B. After weaning, the diaphragm should be resized.
- C. Avoid intercourse during ovulation until the diaphragm size is reassessed.
- D. If weight gain during pregnancy was no more than 20 pounds, the diaphragm is safe to use.

The healthcare provider notes on the fetal monitor that a laboring client has a variable deceleration. Which action should the healthcare provider implement first?
- A. Assess cervical dilation.
- B. Change the client's position.
- C. Administer oxygen via facemask.
- D. Turn off the oxytocin infusion.
Correct Answer: B
Rationale: Changing the client's position is the priority intervention for variable decelerations as it can relieve pressure on the umbilical cord, potentially resolving the deceleration and improving fetal oxygenation. Assessing cervical dilation, administering oxygen via facemask, and turning off the oxytocin infusion are important interventions but addressing the fetal distress caused by variable decelerations takes precedence.
