1. How should fluid balance be assessed in a patient with heart failure?

A. Monitor daily weight
B. Monitor input and output
C. Check for edema
D. Monitor blood pressure

Correct answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.

2. A healthcare professional is reviewing the medical record of a client scheduled for a CT scan with contrast media. The healthcare professional should identify which of the following findings as a contraindication to the procedure?

A. White blood cell count of 6,000/mm³
B. Urine specific gravity of 1.025
C. History of asthma
D. History of allergy to shellfish

Correct answer: D

Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.

3. A nurse is caring for a client who has a new diagnosis of hypothyroidism. Which of the following findings should the nurse expect?

A. Weight gain.
B. Bradycardia.
C. Tachycardia.
D. Heat intolerance.

Correct answer: B

Rationale: The correct answer is B: Bradycardia. Bradycardia, or a slow heart rate, is a common finding in clients with hypothyroidism because of the decreased metabolic rate associated with this condition. Weight gain is also a common symptom of hypothyroidism due to the metabolic changes, making choice A incorrect. Tachycardia, or a rapid heart rate, is typically seen in hyperthyroidism, not hypothyroidism, so choice C is incorrect. Heat intolerance is more commonly associated with hyperthyroidism rather than hypothyroidism, making choice D incorrect.

4. A nurse is caring for a client who has diaper dermatitis. Which of the following actions should the nurse take?

A. Apply zinc oxide ointment to the irritated area
B. Wipe stool from the skin using store-bought baby wipes
C. Apply talcum powder to the irritated area
D. Apply a warm compress to the irritated area

Correct answer: A

Rationale: Correct answer: Applying zinc oxide ointment to the irritated area is the most appropriate action for diaper dermatitis. Zinc oxide is a barrier cream that helps protect the skin and promote healing. Choice B is incorrect because using store-bought baby wipes may contain chemicals or fragrances that can further irritate the skin. Choice C is incorrect as talcum powder can also worsen the condition by drying out the skin. Choice D is incorrect because a warm compress is not typically used for diaper dermatitis; it may provide relief for other conditions but is not the best option for diaper dermatitis.

5. What is the priority intervention for a patient with dehydration?

A. Administer IV fluids
B. Monitor intake and output
C. Administer oral fluids
D. Provide electrolyte replacement

Correct answer: A

Rationale: The correct answer is to administer IV fluids. This intervention is the priority as it helps rapidly restore hydration in patients with dehydration by delivering fluids directly into the bloodstream. Monitoring intake and output (choice B) is important but comes after providing immediate fluid resuscitation. Administering oral fluids (choice C) may not be sufficient for a patient with dehydration who requires rapid rehydration. Providing electrolyte replacement (choice D) is essential but often follows fluid resuscitation to correct any electrolyte imbalances resulting from dehydration.
