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. When preparing a class on newborn care for expectant parents, what content should be taught concerning the newborn infant born at term gestation?

• A. Milia are white marks caused by sebaceous glands and typically resolve within 2 to 4 weeks.
• B. Meconium is the first stool and is typically dark green or black in color.
• C. Vernix caseosa is a white, cheesy substance mainly found in skin folds, providing a protective layer.
• D. Pseudostrabismus in newborns usually self-resolves without the need for intervention.

Correct answer: C

Rationale: Vernix caseosa is a white, cheesy substance that acts as a protective barrier on the skin of newborns, particularly present in skin folds. It helps to prevent dehydration and protect the delicate skin of the newborn from the amniotic fluid in utero. Educating expectant parents about the presence and function of vernix caseosa can help them understand the importance of its preservation during the immediate postnatal period. Choices A, B, and D are incorrect as they do not directly relate to the protective function of vernix caseosa in newborns. Milia are small, white bumps on the skin due to blocked oil glands, meconium is the first stool of a newborn and is typically dark green or black in color, and pseudostrabismus refers to false appearance of misalignment of the eyes, which usually resolves on its own without intervention.

3. A father watching the admission of his newborn to the nursery notices that eye ointment is placed in the infant's eyes. He asks what is the purpose of the ointment. The nurse would be correct in stating that the purpose of the ointment is:

• A. Prevent eye infection.
• B. Dilate the pupil so the red reflex can be visualized.
• C. Clear the infant's vision.
• D. Prevent herpes infection.

Correct answer: A

Rationale: The correct answer is A: Prevent eye infection. Eye ointment, usually containing erythromycin, is applied to prevent neonatal conjunctivitis, which can be caused by bacteria present in the birth canal. It is not used to dilate the pupil, clear the infant's vision, or prevent herpes infection.

4. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.

5. The healthcare provider is preparing to give an enema to a laboring client. Which client requires the most caution when carrying out this procedure?

• A. A gravida 6, para 5 who is 38 years of age and in early labor.
• B. A 37-week primigravida who presents at 100% effacement, 3 cm cervical dilation, and a -1 station.
• C. A gravida 2, para 1 who is at 1 cm cervical dilation and a 0 station admitted for induction of labor due to postdates.
• D. A 40-week primigravida who is at 6 cm cervical dilation and the presenting part is not engaged.

Correct answer: D

Rationale: The client at 40 weeks of gestation with a 6 cm cervical dilation and a presenting part that is not engaged requires the most caution during an enema procedure. An unengaged presenting part increases the risk of cord prolapse, which can be a serious complication during the procedure. This situation demands careful attention to prevent potential complications and ensure the safety of the client and fetus. Choice A is incorrect as being in early labor does not pose the same level of risk as an unengaged presenting part. Choice B describes a client at 37 weeks with signs of early labor but does not indicate the same level of risk as an unengaged presenting part. Choice C involves a client at 1 cm cervical dilation and a 0 station with no mention of an unengaged presenting part, making it a less critical situation compared to an unengaged presentation, as in Choice D.
