1. When admitting a client diagnosed with active tuberculosis to isolation, which infection control measures should the nurse implement?
- A. Negative pressure environment
- B. Contact precautions
- C. Droplet precautions
- D. Protective environment
Correct answer: A
Rationale: The correct answer is A: Negative pressure environment. Tuberculosis is transmitted through airborne particles, so a negative pressure room is essential to prevent the spread of the bacteria. Choice B, contact precautions, are used for infections spread by direct or indirect contact, not for tuberculosis. Choice C, droplet precautions, are for infections transmitted through respiratory droplets, not airborne particles like tuberculosis. Choice D, protective environment, is used for protecting immunocompromised patients from outside pathogens, not for preventing the spread of tuberculosis.
2. The nurse administers an oral antiviral to a client with shingles. Which finding is most important for the nurse to report to the healthcare provider?
- A. Decreased white blood cell count
- B. Pruritus and muscle aches
- C. Elevated liver function tests
- D. Vomiting and diarrhea
Correct answer: C
Rationale: The correct answer is C: Elevated liver function tests. When administering antivirals, especially orally, monitoring liver function tests is crucial as it may indicate liver toxicity. This finding should be reported promptly to the healthcare provider to prevent further complications. Choice A, decreased white blood cell count, may be expected with certain antivirals but is not the most critical finding in this scenario. Pruritus and muscle aches (choice B) are common side effects of antivirals and do not require immediate reporting. Vomiting and diarrhea (choice D) are also common side effects that may not be as concerning as elevated liver function tests.
3. A client who is bleeding after a vaginal delivery receives a prescription for methylergonovine (Methergine) 0.4 mg IM every 2 hours, not to exceed 5 doses. The medication is available in ampules containing 0.2 mg/ml. What is the maximum dosage in mg that the nurse should administer to this client? (Enter numeric value only)
- A. 2
- B. 3
- C. 4
- D. 5
Correct answer: A
Rationale: To calculate the maximum dosage in mg that the nurse should administer, multiply the dose per administration (0.4 mg) by the maximum number of doses allowed (5 doses): 0.4 mg/dose * 5 doses = 2 mg. Therefore, the nurse should administer a maximum dosage of 2 mg to the client. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
4. A client with diabetes mellitus tells the nurse that she uses cranberry juice to help prevent urinary tract infection. What instruction should the nurse provide?
- A. Ensure to drink sugar-free cranberry juice
- B. Drinking cranberry juice does not prevent infection
- C. Cranberries do not affect insulin levels
- D. Excessive cranberry juice consumption can lead to constipation
Correct answer: B
Rationale: The correct answer is B: Drinking cranberry juice does not prevent urinary tract infections and should not be relied upon as a preventive measure. While cranberry juice is often associated with preventing UTIs, there is limited scientific evidence to support this claim. Choice A is incorrect because the sugar content in cranberry juice is not the main concern when discussing its role in preventing UTIs. Choice C is incorrect as there is no significant evidence to suggest cranberries affecting insulin levels. Choice D is incorrect as constipation is not a typical side effect of consuming cranberry juice; however, excessive consumption may lead to gastrointestinal discomfort.
5. The healthcare provider prescribed furosemide for a 4-year-old child with a ventricular septal defect. Which outcome indicates to the nurse that this pharmacological intervention was effective?
- A. Urine specific gravity changing from 1.021 to 1.031
- B. Daily weight decrease of 2 pounds (0.9 kg)
- C. Blood urea nitrogen (BUN) increasing from 8 to 12 mg/dl (2.9 to 4.3)
- D. Urinary output decreasing by 5 ml/hour
Correct answer: B
Rationale: The correct answer is B. A daily weight decrease of 2 pounds (0.9 kg) is the most appropriate outcome to indicate the effectiveness of furosemide in a child with a ventricular septal defect. Furosemide is a diuretic medication that helps reduce fluid retention. Therefore, a decrease in weight reflects a reduction in fluid volume, which is the desired effect of furosemide. Choices A, C, and D are incorrect because changes in urine specific gravity, blood urea nitrogen (BUN) levels, and urinary output do not directly reflect the effectiveness of furosemide in this context.
