1. In the management of heart failure, which diuretic is preferred due to its demonstrated significant mortality reduction in patients with heart failure?

• A. Furosemide (Lasix)
• B. Hydrochlorothiazide (HydroDIURIL)
• C. Spironolactone (Aldactone)
• D. Mannitol (Osmitrol)

Correct answer: C

Rationale: Spironolactone, a potassium-sparing diuretic, is the preferred choice in heart failure due to its cardio-protective effect, leading to reduced mortality in patients with heart failure. It is used to manage both hypertension and edema, making it a valuable option in heart failure treatment.

2. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

3. Which is the priority nursing assessment when providing care for an infant at risk for dehydration?

• A. Urine output
• B. Urine specific gravity
• C. Vital signs
• D. Daily weight

Correct answer: D

Rationale: The correct answer is Daily weight. Daily weight is a crucial assessment in infants at risk for dehydration because changes in weight can indicate fluid balance and dehydration status. It is essential to monitor daily weight to promptly identify and manage dehydration in infants.

4. A healthcare professional is assessing an infant who has heart failure. Which of the following findings should the healthcare professional expect?

• A. Weight gain
• B. Bounding pulses
• C. Hyperactivity
• D. Increased urine output

Correct answer: A

Rationale: In infants with heart failure, one of the key manifestations is weight gain due to fluid retention. The heart's inability to pump effectively can lead to fluid buildup in the body, causing weight gain. Bounding pulses, hyperactivity, and increased urine output are not typically associated with heart failure in infants. Bounding pulses are associated with conditions like aortic regurgitation, hyperactivity can be a sign of other issues, and increased urine output is not a common finding in heart failure.

5. While caring for four different pediatric clients, which child is at the highest risk for dehydration?

• A. 7-year-old child with migraine headaches
• B. 4-year-old child with a broken arm
• C. 2-year-old child with cellulitis of the left leg
• D. 18-month-old child with tachypnea

Correct answer: D

Rationale: The 18-month-old child with tachypnea is at the highest risk for dehydration due to increased insensible water loss associated with rapid breathing.
