Nursing Elites

1. The nurse is caring for a 2-day old neonate who has not passed meconium and has a swollen abdomen. The healthcare provider reviews the flat plate X-ray of the abdomen and makes a tentative diagnosis of Hirschsprung's disease. Which pathophysiological process is consistent with this neonate's clinical picture?

• A. The congenital absence of parasympathetic ganglion cells to large intestine produces no peristalsis.
• B. Pyloric obstruction causes reflux and projectile hematemesis.
• C. Partial imperforated anal opening limits passage of stools.
• D. Peristalsis moving against the intestinal obstruction causing hyperactivity of the bowel.

Correct answer: A

Rationale: Hirschsprung's disease is caused by the absence of parasympathetic ganglion cells in the large intestine, leading to a lack of peristalsis and obstruction.

2. During an examination for possible cryptorchidism in an infant, what technique should be used?

• A. Place the infant in a warm room and use a calm approach.
• B. Hold the scrotum and palpate gently.
• C. Cleanse the penis with an antiseptic-soaked pad.
• D. Position the infant in a warm room to prevent muscle contraction.

Correct answer: D

Rationale: When examining an infant for cryptorchidism, it is important to position the infant in a warm room to prevent muscle contraction, which could cause the testes to retract. Placing the infant in a side-lying position may not be necessary for this specific examination. Holding the penis or retracting the foreskin is not relevant to the assessment for cryptorchidism. Cleansing the penis with an antiseptic pad is not indicated for this examination.

3. A 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?

• A. Slowly increasing urinary output over the last week.
• B. Respiratory rate changes from the 40s to the 60s.
• C. Changes in apical heart rate from the 180s to the 140s.
• D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.

Correct answer: C

Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective. Choices A, B, and D are incorrect because they do not directly reflect the expected outcome of epoetin alfa therapy. Increasing urinary output, changes in respiratory rate, and decreasing bilirubin levels are not primary indicators of the drug's effectiveness in this context.

4. A new mother calls the nurse stating that she wants to start feeding her 6-month-old child something besides breast milk, but is concerned that the infant is too young to start eating solid foods. How should the nurse respond?

• A. Advise the mother to wait at least another month before starting any solid foods.
• B. Instruct the mother to offer a few spoons of 2 or 3 pureed fruits at each meal.
• C. Reassure the mother that the infant is old enough to eat iron-fortified cereal.
• D. Encourage the mother to schedule a developmental assessment of the infant.

Correct answer: C

Rationale: At 6 months, infants are generally ready to start eating iron-fortified cereals as their iron stores begin to deplete. Introducing iron-fortified cereals at this age helps meet the infant's nutritional needs, particularly for iron, which becomes deficient as the infant's iron reserves diminish. It is a safe and appropriate first food to introduce to infants around 6 months of age, along with continued breastfeeding or formula feeding. Choice A is incorrect because waiting another month is not necessary if the infant is 6 months old. Choice B is incorrect as introducing pureed fruits as the first food may not provide the necessary iron that the infant needs at this stage. Choice D is also incorrect as scheduling a developmental assessment is not indicated solely based on the desire to start solid foods; it is more appropriate to reassure the mother about starting iron-fortified cereal.

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.
