Nursing Elites

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 prenatal visit, the nurse discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

3. A pregnant woman comes to the prenatal clinic for an initial visit. In reviewing her childbearing history, the client indicates that she has delivered premature twins, one full-term baby, and has had no abortions. Which GTPAL should the LPN/LVN document in this client's record?

• A. 3-1-2-0-3.
• B. 4-1-2-0-3.
• C. 2-1-2-1-2.
• D. 3-1-1-0-3.

Correct answer: D

Rationale: The correct GTPAL for this client is 3-1-1-0-3. G (Gravida) is 3, indicating a total of 3 pregnancies. T (Term) is 1, representing 1 full-term delivery. P (Preterm) is 1, not 2 as mentioned in the question, as twins count as one pregnancy event. A (Abortions) is 0, and L (Living) is 3, indicating 3 living children (twins count as 1). Therefore, the correct answer is 3-1-1-0-3.

4. The LPN/LVN is preparing a client with a term pregnancy who is in active labor for an amniotomy. What equipment should the nurse have available at the client's bedside?

• A. Litmus paper.
• B. Fetal scalp electrode.
• C. A sterile glove.
• D. Needle and Thread

Correct answer: C

Rationale: For performing an amniotomy, the nurse should have a sterile glove to maintain asepsis and an amniotic hook to rupture the amniotic sac. Litmus paper is not required for this procedure, and a fetal scalp electrode is used for fetal monitoring, not for an amniotomy.

5. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.
