Nursing Elites

1. What is an important nursing responsibility when a dysrhythmia is suspected?

• A. order an immediate electrocardiogram
• B. count the radial pulse every 1 minute for five times
• C. count the apical pulse for 1 full minute, and compare the rate with the radial pulse rate
• D. have someone else take the radial pulse simultaneously with the apical pulse

Correct answer: C

Rationale: When a dysrhythmia is suspected, an important nursing responsibility is to count the apical pulse for 1 full minute and then compare this rate with the radial pulse rate. This method helps in identifying dysrhythmias as it allows for a direct comparison of the heart's rhythm at two different pulse points. Ordering an immediate electrocardiogram (Choice A) may be necessary but should not be the first step. Counting the radial pulse multiple times (Choice B) is not as accurate as comparing rates directly. Having someone else take the radial pulse simultaneously (Choice D) may introduce errors and inconsistencies in the measurement.

2. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted as an autosomal recessive trait.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.

3. A child is admitted with extensive burns. The nurse notes burns on the child’s lips and singed nasal hairs. The nurse should suspect that the child has a(n)

• A. chemical burn
• B. inhalation injury
• C. electrical burn
• D. hot-water scald

Correct answer: B

Rationale: Burns on the lips and singed nasal hairs are indicative of an inhalation injury. This suggests that the child has likely inhaled hot gases or smoke, leading to damage in the respiratory tract. Choice A, chemical burn, is incorrect because the symptoms described are more aligned with inhalation rather than direct contact with chemicals. Choice C, electrical burn, is incorrect as there are no mentions of contact with an electrical source. Choice D, hot-water scald, is also incorrect as the presentation of burns on the lips and singed nasal hairs is not characteristic of scald injuries.

4. A 7-year-old child has an altered mental status, high fever, and a generalized rash. You perform your assessment and initiate oxygen therapy. En route to the hospital, you should be most alert for:

• A. vomiting
• B. seizures
• C. combativeness
• D. respiratory distress

Correct answer: B

Rationale: In a pediatric patient presenting with altered mental status, high fever, and a generalized rash, seizures are a significant concern. Febrile seizures can occur in children with high fevers and may lead to further complications. It is crucial to monitor for seizures and be prepared to manage them promptly. Vomiting, combativeness, and respiratory distress are also important considerations in pediatric patients; however, given the clinical presentation described, seizures take priority as they are a common complication in this scenario.

5. What clinical manifestation of tetralogy of Fallot should the nurse expect when caring for children with this diagnosis?

• A. Slow respirations
• B. Clubbing of fingers
• C. Decreased RBC counts
• D. Subcutaneous hemorrhages

Correct answer: B

Rationale: The correct answer is B: Clubbing of fingers. Clubbing of fingers is a common manifestation in children with tetralogy of Fallot due to chronic hypoxia. This condition causes the fingertips and nails to enlarge, creating a bulbous or club-like appearance. Slow respirations (Choice A) are not a typical clinical manifestation of tetralogy of Fallot. Decreased RBC counts (Choice C) may be seen in conditions like anemia but are not specific to tetralogy of Fallot. Subcutaneous hemorrhages (Choice D) are not a characteristic clinical manifestation of tetralogy of Fallot.
