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. In contrast to the contractions associated with true labor, Braxton-Hicks contractions:

• A. generally follow rupture of the amniotic sac and occur with regularity.
• B. may be intensified by activity and are accompanied by a pink discharge.
• C. do not increase in intensity and are alleviated by a change in position.
• D. consistently become stronger and are not alleviated by changing position.

Correct answer: C

Rationale: Braxton-Hicks contractions are irregular and usually do not increase in intensity. Unlike true labor contractions, they tend to alleviate with a change in position, making option C the correct choice. Choices A, B, and D are incorrect because Braxton-Hicks contractions do not follow rupture of the amniotic sac, are not intensified by activity or accompanied by a pink discharge, and do not consistently become stronger or are not alleviated by changing position.

3. Which intervention is not appropriate for the hospitalized adolescent?

• A. Allowing the adolescent to assist with procedures when possible.
• B. Encouraging them to discuss their thoughts and feelings about the hospitalization.
• C. Encouraging them to remain in the room throughout the hospitalization to ensure adequate rest periods.
• D. Encouraging peer visitation.

Correct answer: C

Rationale: Encouraging the adolescent to remain in the room throughout the hospitalization to ensure adequate rest periods is not appropriate. It is crucial for adolescents to have opportunities for physical activity and social interaction to promote their well-being during hospitalization. Allowing them to assist with procedures when possible can empower them and provide a sense of control. Encouraging discussions about their thoughts and feelings helps address their emotional needs. Facilitating peer visitation fosters social support, which is beneficial for their well-being. Therefore, choice C is the least appropriate as it restricts important aspects of the adolescent's development and coping mechanisms during hospitalization.

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. Your assessment of a 5-year-old child reveals that he is unresponsive with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min. Treatment for this child should include:

• A. high-flow oxygen via non-rebreathing mask and rapid transport.
• B. assisted ventilation with a bag-mask device and rapid transport.
• C. positive-pressure ventilation, chest compressions, and rapid transport.
• D. back slaps and chest thrusts while attempting artificial ventilations.

Correct answer: C

Rationale: In a 5-year-old child who is unresponsive with severe bradycardia and bradypnea, the priority is to provide positive-pressure ventilation to support breathing and perform chest compressions to support circulation. This child is in cardiac arrest, and the recommended treatment according to pediatric basic life support guidelines involves a combination of positive-pressure ventilation and chest compressions to maintain oxygenation and circulation. Rapid transport to a medical facility for further advanced care is crucial in this critical situation. Choices A, B, and D are incorrect because high-flow oxygen via non-rebreathing mask, assisted ventilation with a bag-mask device, and back slaps with chest thrusts are not sufficient in a cardiac arrest situation where the child requires immediate positive-pressure ventilation and chest compressions to maintain oxygenation and circulation.
