Nursing Elites

1. The health care provider is treating a child with meningitis with a course of antibiotic therapy. When should the nurse expect the child to be out of isolation?

• A. When the course of antibiotics is complete
• B. When a negative CNS culture is obtained
• C. When the antibiotics have been initiated for 24 hours
• D. When the child has no symptoms of the disease

Correct answer: C

Rationale: The correct answer is C because a child with bacterial meningitis should be isolated for at least 24 hours until antibiotic therapy has been initiated. This period allows the antibiotics to start working against the infection, reducing the risk of spreading it to others. Choice A is incorrect because isolation is not solely based on completing the course of antibiotics; the initiation is crucial. Choice B is incorrect as waiting for a negative CNS culture may take longer and delay necessary precautions. Choice D is incorrect as symptom resolution does not guarantee the eradication of the infection and may still pose a risk of transmission.

2. What is the major criterion for diagnosing cognitive impairment in a child?

• A. An IQ of 75 or less
• B. Subaverage functioning
• C. An IQ of 70 or less
• D. Onset before 18

Correct answer: C

Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.

3. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?

• A. 16 ml/hour.
• B. 18 ml/hour.
• C. 20 ml/hour.
• D. 22 ml/hour.

Correct answer: C

Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.

4. The nurse is assessing a client who has herpes zoster. Which question will allow the nurse to gather further information about this condition?

• A. Has everyone at home already had varicella?
• B. Have the antifungal creams been effective?
• C. Do your family members share combs and brushes?
• D. Do you have any dry patches on your feet and hands?

Correct answer: A

Rationale: The correct answer is A: 'Has everyone at home already had varicella?' Herpes zoster (shingles) is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. By knowing if others at home had varicella (chickenpox), the nurse can assess the risk of transmission and provide appropriate guidance. Choice B is incorrect because antifungal creams are not effective for herpes zoster, which is a viral infection. Choice C is irrelevant to herpes zoster as it pertains to sharing personal items that may transmit head lice or certain skin infections. Choice D is also unrelated as it focuses on dry patches, not typical manifestations of herpes zoster which presents as a painful rash.

5. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.
