Nursing Elites

1. The nurse is with a client when the healthcare provider explains that the biopsy classifies the results as a T1N0M0 tumor. What response should the nurse provide first?

• A. The letters represent tumor size, node involvement, and metastasis in cancer staging.
• B. The letters stand for tumor size, node involvement, and metastasis.
• C. Let me explain the cancer staging to you.
• D. Would you like further clarification on the tumor staging?

Correct answer: B

Rationale: Choice B is the correct answer as it accurately explains that the letters T, N, and M in cancer staging represent tumor size, node involvement, and metastasis, respectively. Understanding this staging system helps the client comprehend the extent and severity of the disease. Choices A, C, and D are incorrect. Choice A has the correct information but is not the most precise response. Choice C is vague and does not directly address the client's need for clarification. Choice D offers further clarification without directly addressing the initial explanation provided by the healthcare provider.

2. Which nonfood item is the most common cause of respiratory arrest in young children?

• A. Broken rattles
• B. Buttons
• C. Pacifiers
• D. Latex balloons

Correct answer: D

Rationale: The correct answer is D, Latex balloons. Latex balloons can pose a significant choking hazard to young children if inhaled, potentially leading to respiratory arrest. Broken rattles, buttons, and pacifiers are not typically known to cause respiratory arrest in young children. While these items can present choking hazards as well, the most common cause of respiratory arrest among young children is due to inhaling latex balloons.

3. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

4. A client is being treated for dehydration. Which clinical finding would indicate that treatment is effective?

• A. Dry mucous membranes
• B. Increased urine output
• C. Tachycardia
• D. Hypotension

Correct answer: B

Rationale: The correct answer is B: Increased urine output. When a client is being treated for dehydration, increased urine output is a positive indication that the treatment is effective. This signifies that the body is beginning to rehydrate and eliminate excess fluid. Choices A, C, and D are incorrect because dry mucous membranes, tachycardia, and hypotension are all associated with dehydration and would not be signs of effective treatment.

5. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.
