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. When preventing cardiac arrest in infants and small children, the primary focus should be on:

• A. Providing immediate transport.
• B. Ensuring adequate ventilation.
• C. Keeping the child warm.
• D. Avoiding upsetting the child.

Correct answer: B

Rationale: The correct approach to prevent cardiac arrest in infants and small children is to ensure adequate ventilation. In these cases, maintaining proper oxygenation and ventilation is crucial for sustaining life. Providing immediate transport, keeping the child warm, or avoiding upsetting the child are important considerations but ensuring adequate ventilation takes precedence in preventing cardiac arrest and supporting the child's vital functions.

3. Which of the following are clinical types of diarrhoea EXCEPT?

• A. Acute watery
• B. Bloody diarrhoea
• C. Persistent diarrhoea
• D. Secretory diarrhoea

Correct answer: D

Rationale: Secretory diarrhoea is not a clinical type but a distinct mechanism of diarrhoea characterized by increased electrolyte secretion. Acute watery, bloody, and persistent diarrhoea are recognized clinical types associated with different underlying causes and pathophysiologies. Acute watery diarrhoea is common in infectious gastroenteritis, bloody diarrhoea can be caused by inflammatory conditions or infections, and persistent diarrhoea typically lasts for more than 14 days due to various reasons like infections, malabsorption, or inflammatory bowel diseases.

4. A child was brought to the emergency department with complaints of nausea, vomiting, and fruity-scented breath. The resident on duty diagnosed the child with diabetic ketoacidosis. Which of the following should the nurse expect to administer?

• A. Potassium chloride IV infusion.
• B. Dextrose 5% IV infusion.
• C. Ringer's Lactate.
• D. Normal saline IV infusion

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is a state of dehydration and electrolyte imbalance. Normal saline is the initial fluid of choice to help restore intravascular volume and improve electrolyte balance. It also helps to correct acidosis. Potassium chloride IV infusion is commonly added to the treatment regimen once kidney function is confirmed to prevent hypokalemia. Dextrose 5% IV infusion is not the first-line treatment for DKA as it can worsen hyperglycemia. Ringer's Lactate is not typically used as the initial fluid for managing DKA as it contains potassium and could worsen hyperkalemia.

5. 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.
