1. 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.

2. Management for a woman presenting with a prolapsed umbilical cord includes all of the following, EXCEPT:

• A. lifting the baby's head off the umbilical cord.
• B. placing the mother in a position that elevates her hips.
• C. ensuring that the cord stays moist during transport.
• D. relieving pressure off the cord by gently pulling on it.

Correct answer: D

Rationale: In cases of prolapsed umbilical cord, it is crucial to manage the situation promptly. The correct steps include lifting the baby's head off the umbilical cord to reduce pressure, placing the mother in a position that elevates her hips to relieve pressure on the cord, and ensuring that the cord stays moist. Pulling on the cord is not recommended as it can further compromise fetal circulation and should be avoided. Therefore, relieving pressure off the cord by gently pulling on it is not a recommended management approach in cases of prolapsed umbilical cord.

3. 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.

4. After an advanced airway device has been inserted in a 6-month-old infant in cardiopulmonary arrest, you should deliver ventilations at a rate of:

• A. 10 to 12 breaths/min.
• B. 12 to 20 breaths/min.
• C. 6 to 8 breaths/min.
• D. 8 to 10 breaths/min.

Correct answer: D

Rationale: The appropriate ventilation rate for an infant with an advanced airway is 8 to 10 breaths per minute.

5. Are most children with hypertension asymptomatic?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is true. In many cases, children with hypertension do not show any symptoms, making it challenging to diagnose them. Regular blood pressure checks are crucial to detect hypertension early, as it can have serious health implications if left untreated. Choice B is incorrect because most children with hypertension do not exhibit symptoms, hence being asymptomatic. Choices C and D are empty as they do not provide additional options.
