1. Which anatomic malformations are associated with Tetralogy of Fallot?

A. A sub-aortic septal defect, an overriding aorta, left ventricular hypertrophy, and right ventricular outflow
B. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and left ventricular outflow
C. A sub-aortic septal defect, an overriding aorta, pulmonary atresia, and right ventricular outflow
D. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow

Correct answer: D

Rationale: Tetralogy of Fallot is characterized by a combination of four heart defects: a sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow obstruction. This leads to mixing of oxygen-poor and oxygen-rich blood, resulting in cyanosis. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not accurately describe the specific combination of anatomic malformations seen in Tetralogy of Fallot.

2. Low birth weight is defined as a newborn's weight of:

A. 2500 grams or less at birth, regardless of gestational age.
B. 1500 grams or less at birth, regardless of gestational age.
C. 2500 grams or less at birth, according to gestational age.
D. 1500 grams or less at birth, according to gestational age.

Correct answer: A

Rationale: Low birth weight is defined as 2500 grams or less at birth, regardless of gestational age. This means that any newborn weighing 2500 grams or less is considered to have a low birth weight, irrespective of how many weeks they were in the womb. Choices B, C, and D are incorrect because they specify a weight of 1500 grams or less, which is not the standard definition of low birth weight. The correct definition is 2500 grams or less, not influenced by gestational age.

3. Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:

A. 1 in 85 births.
B. 1 in 5400 births.
C. 1 in 2700 births.
D. 1 in 540 births

Correct answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

4. A nurse in the emergency department is preparing to care for a client who arrived via ambulance. The client is disoriented and has a cardiac arrhythmia. Which of the following actions should the nurse take?

A. Proceed with treatment without obtaining written consent
B. Contact the client's next of kin to obtain consent for treatment
C. Have the client sign a consent for treatment
D. Notify risk management before initiating treatment

Correct answer: A

Rationale: In emergency situations where a client is disoriented and has a cardiac arrhythmia, obtaining written consent may not be possible due to the urgency of the situation. The priority is to provide immediate treatment to ensure patient safety. Contacting the next of kin or having the client sign a consent form would cause unnecessary delays in providing critical care. Notifying risk management before initiating treatment is not the most appropriate action when dealing with a time-sensitive situation like a cardiac arrhythmia.

5. A nurse is preparing to discharge a client who requires home oxygen. The equipment company has not yet delivered the oxygen tank. Which of the following actions should the nurse take?

A. Send an oxygen tank from the facility home with the client
B. Instruct the client's family to contact the insurance provider about the oxygen equipment
C. Contact social services about the delivery of the oxygen equipment
D. Notify the provider about the delayed oxygen tank delivery

Correct answer: C

Rationale: The correct action for the nurse to take is to contact social services about the delivery of the oxygen equipment. This ensures that the necessary equipment is delivered to the client's home promptly. Choice A is incorrect because sending an oxygen tank from the facility is not a sustainable solution and may lead to legal and safety issues. Choice B is incorrect as contacting the insurance provider is not the appropriate course of action to address the delayed delivery. Choice D is also incorrect because notifying the provider about the delay may not directly lead to the timely delivery of the oxygen equipment.
