Nursing Elites

1. A nurse is caring for a client receiving theophylline for chronic obstructive pulmonary disease (COPD). Which of the following client findings indicates the need for immediate intervention?

• A. Productive cough
• B. Drowsiness
• C. Vomiting
• D. Polyuria

Correct answer: D

Rationale: Polyuria is a sign of theophylline toxicity and requires immediate intervention. Theophylline toxicity can lead to serious complications, and polyuria is a concerning symptom that indicates the need for urgent medical attention. Productive cough, drowsiness, and vomiting are common side effects of theophylline but are not typically indicative of immediate life-threatening issues like polyuria in the context of theophylline toxicity.

2. A healthcare provider is preparing to administer a measles, mumps, and rubella (MMR) vaccine to an adult client. Which of the following is a contraindication to this vaccine?

• A. The possibility of pregnancy within 4 weeks
• B. Client allergy to strawberries
• C. Client history of genital herpes
• D. The possibility of overseas travel in the next month

Correct answer: A

Rationale: The correct answer is A. Pregnancy or the possibility of pregnancy within 4 weeks is a contraindication for receiving the MMR vaccine. Choice B, client allergy to strawberries, is not a contraindication to the MMR vaccine. Choice C, client history of genital herpes, is not a contraindication for the MMR vaccine. Choice D, the possibility of overseas travel in the next month, is not a contraindication to the MMR vaccine.

3. A client receiving epoetin alfa therapy for anemia is being monitored for therapeutic effects. Which of the following laboratory values indicates the medication is effective?

• A. White blood cell count
• B. Hematocrit
• C. Platelet count
• D. Red blood cell count

Correct answer: B

Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity. Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.

4. A nurse is administering metformin to a client with type 2 diabetes. Which of the following adverse effects should the nurse monitor for in this client?

• A. Diarrhea
• B. Hyperglycemia
• C. Hypoglycemia
• D. Lactic acidosis

Correct answer: D

Rationale: The correct answer is D, Lactic acidosis. Lactic acidosis is a rare but serious adverse effect of metformin use. Metformin is not known to cause hyperglycemia or hypoglycemia. Diarrhea is a common gastrointestinal side effect of metformin but is not as serious as lactic acidosis, which requires immediate medical attention.

5. A nurse is reviewing a client's medication regimen. Which of the following medications places the client at increased risk for digoxin toxicity?

• A. Calcium channel blockers
• B. Potassium-sparing diuretics
• C. Beta blockers
• D. Loop diuretics

Correct answer: D

Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.
