1. Which cardiac defects are associated with tetralogy of Fallot?
- A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
- B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
- C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
- D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect
Correct answer: C
Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.
2. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the health care provider?
- A. 100 to 150 mL
- B. 155 to 250 mL
- C. 255 to 360 mL
- D. 365 to 500 mL
Correct answer: B
Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL to prevent overdistension and potential harm. Choice A (100 to 150 mL) is too low and may not be effective in achieving the desired outcome. Choices C (255 to 360 mL) and D (365 to 500 mL) exceed the safe range for a 2-year-old child and can lead to overdistension, electrolyte imbalance, or other complications. Therefore, the correct answer is B.
3. The nurse is caring for a child who has been admitted for a sickle cell crisis. What would the nurse do first to provide adequate pain management?
- A. Administer a nonsteroidal anti-inflammatory drug (NSAID) as ordered.
- B. Use guided imagery and therapeutic touch.
- C. Administer meperidine as ordered.
- D. Initiate pain assessment with a standardized pain scale.
Correct answer: D
Rationale: Initiating pain assessment with a standardized pain scale is crucial in effectively managing pain during a sickle cell crisis. This initial step helps the nurse understand the severity of the pain, which guides subsequent interventions. Administering medications, such as NSAIDs or meperidine, should only be done after a thorough pain assessment to ensure appropriate and individualized treatment. Using guided imagery and therapeutic touch may be beneficial as adjunct interventions, but they should not replace the essential first step of assessing the pain level accurately.
4. When administering IV fluids to a dehydrated infant, what intervention is most important at this time?
- A. Continuing the prescribed flow rate
- B. Monitoring the intravenous drop rate
- C. Calculating the total necessary intake
- D. Maintaining the fluid at body temperature
Correct answer: B
Rationale: Monitoring the intravenous drop rate is the most crucial intervention when administering IV fluids to a dehydrated infant. This ensures that the correct amount of fluids is being delivered to the infant at the appropriate rate. While continuing the prescribed flow rate (Choice A) may be important, it does not allow for real-time adjustments that may be necessary during the infusion. Calculating the total necessary intake (Choice C) should have been determined before initiating IV therapy. Maintaining the fluid at body temperature (Choice D) is important for patient comfort but is not as critical as ensuring the proper administration of fluids.
5. 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.
