Nursing Elites

1. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?

• A. Metabolic acidosis
• B. Respiratory acidosis
• C. Respiratory alkalosis
• D. Metabolic alkalosis

Correct answer: C

Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.

2. The healthcare provider is caring for a 3-year-old child who is hospitalized with dehydration. The child is now receiving IV fluids and has started to produce urine. What is the best indicator that the child’s dehydration is improving?

• A. The child’s urine output has increased
• B. The child’s skin turgor is normal
• C. The child’s weight has increased
• D. The child’s vital signs are stable

Correct answer: A

Rationale: An increase in urine output is a reliable indicator that the child's hydration status is improving. Adequate urine output signifies that the kidneys are functioning properly and that the body is effectively eliminating waste and excess fluids, indicating improved hydration levels. The other options are not as direct indicators of hydration status. Skin turgor and weight changes can be influenced by various factors, and stable vital signs do not specifically reflect hydration status.

3. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

4. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
• B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
• C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
• D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles

Correct answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.

5. An adolescent female who comes to the school clinic is reluctant to confide her concerns to the practical nurse (PN). The PN tells the teen that confidentiality and privacy are maintained unless a life-threatening situation arises. Which principle supports the PN's response?

• A. The adolescent should be encouraged to seek help outside of the school clinic.
• B. Disclosures from the adolescent should be kept confidential.
• C. Honest information ensures establishing a trusting relationship.
• D. Minor adolescents should not be encouraged to disclose private concerns.

Correct answer: C

Rationale: The correct principle supporting the practical nurse's response is that honest information ensures establishing a trusting relationship. By assuring confidentiality and privacy to the adolescent unless there is a life-threatening situation, the practical nurse fosters an environment where the teen feels safe to share their concerns openly. This approach helps build trust, encouraging effective communication and support for the adolescent's well-being. Choices A, B, and D are incorrect because encouraging seeking help outside the school clinic, keeping disclosures confidential, and discouraging minor adolescents from sharing private concerns do not address the immediate need to build trust and ensure the well-being of the adolescent in a school setting.
