Nursing Elites

1. A client has just been diagnosed with active tuberculosis. Which of the following nursing interventions should the nurse perform to prevent transmission to others?

• A. Begin drug therapy within 72 hours of diagnosis
• B. Place the client in a positive-pressure room
• C. Initiate standard precautions
• D. Place the client in a negative-pressure room

Correct answer: D

Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.

2. In children suspected to have a diagnosis of diabetes, which one of the following complaints would be most likely to prompt parents to take their school-age child for evaluation?

• A. Polyphagia
• B. Dehydration
• C. Bedwetting
• D. Weight loss

Correct answer: C

Rationale: The correct answer is 'Bedwetting.' One of the initial symptoms of type 1 diabetes in children is bedwetting. Parents are likely to notice bedwetting in a school-age child, prompting them to seek evaluation. Polyphagia (excessive hunger) and weight loss are also common symptoms of diabetes but may not be as readily noticeable to parents compared to bedwetting. Dehydration is a consequence of diabetes rather than an early symptom that would prompt parents for evaluation.

3. A client had a closed reduction of a fractured right wrist followed by the application of a fiberglass cast 12 hours ago. Which finding requires immediate attention?

• A. Capillary refill of fingers on right hand is 3 seconds
• B. Skin warm to touch and normally colored
• C. Client reports prickling sensation in the right hand
• D. Slight swelling of fingers of right hand

Correct answer: C

Rationale: A prickling sensation in the right hand is indicative of compartment syndrome, a serious condition that can lead to tissue damage and impaired circulation. Immediate attention is required to prevent complications. Capillary refill of 3 seconds, warm and normally colored skin, and slight swelling of fingers are expected findings after a closed reduction and casting. These findings do not typically indicate a critical issue and can be managed with routine monitoring.

4. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

5. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?

• A. Anesthesia reaction
• B. Hyperglycemia
• C. Hypoglycemia
• D. Diabetic ketoacidosis

Correct answer: C

Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.
