1. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:
- A. Increases peripheral vascular resistance
- B. Decreases arterial blood flow away from the heart
- C. It's a common resting position when a child is tachycardic
- D. Increases the workload of the heart
Correct answer: A
Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.
2. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?
- A. Sodium bicarbonate from renal compensation
- B. Potassium from cell death
- C. Glucose from carbohydrate metabolism
- D. Ketone bodies from fat metabolism
Correct answer: D
Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.
3. What is the appropriate technique for performing two-rescuer CPR on a 4-year-old child?
- A. 15 compressions to 2 ventilations, compressing the sternum with your thumbs, and delivering at least 100 compressions per minute.
- B. 30 compressions to 2 ventilations, compressing the chest one third the depth of the chest, and delivering each breath over 1 second.
- C. 15 compressions to 2 ventilations, compressing the sternum with the heel of your hand, and ventilating until visible chest rise occurs.
- D. 30 compressions to 2 ventilations, compressing the sternum with the heel of both hands, and delivering each breath over 1 to 2 seconds.
Correct answer: C
Rationale: When performing two-rescuer CPR on a 4-year-old child, the appropriate technique involves 15 compressions to 2 ventilations. Compressions should be done by pressing the child's sternum with the heel of your hand. Ventilations should be given until visible chest rise occurs. This technique ensures effective CPR delivery for a child in need of resuscitation.
4. Which statement best describes direct contact as a mode of pathogen transmission?
- A. Transmission through large aerosols produced by sneezing or coughing
- B. Transfer of an infectious agent by suspended air particles from a reservoir to a host
- C. Transmission of infectious agents carried by dust
- D. Transmission through skin-to-skin contact or body fluids
Correct answer: D
Rationale: Direct contact transmission occurs when pathogens are spread through skin-to-skin contact or body fluids. This mode of transmission includes activities like touching, kissing, or sexual contact where infectious agents can pass directly from one person to another. It does not involve large aerosols, suspended air particles, or dust as carriers of the pathogen.
5. Sometimes, people with congestive heart failure develop arrhythmias of the heart. These irregular rhythms can be conducive to developing a blood clot. Physicians frequently treat people with 'blood thinning' medicines that require regulation of the density of the blood. Which of these is the name for a blood-thinner?
- A. Erythromycin
- B. Tetracycline
- C. Warfarin
- D. Amoxicillin
Correct answer: C
Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.
