Nursing Elites

1. The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?

• A. Inflammation of the mucous membrane & bronchospasm
• B. Increased mucus production and bronchoconstriction
• C. Allergic reactions and hyperventilation
• D. Airway narrowing and decreased lung capacity

Correct answer: A

Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.

2. The healthcare provider prescribes a fluid challenge of 0.9% sodium chloride 1,000 ml to be infused over 4 hours. The IV administration set delivers 10gtt/ml. How many gtt/minute should the nurse regulate the infusion? (Enter a numeric value only. If rounding is required, round to the nearest whole number.)

• A. 42
• B.
• C.
• D.

Correct answer: A

Rationale: To calculate the rate: (1000 ml / 4 hours) = 250 ml/hour; (250 ml/hour) / (60 minutes/hour) = 4.17 ml/minute; (4.17 ml/minute) * (10 gtt/ml) = 41.7 gtt/minute, rounded to 42 gtt/minute. Therefore, the nurse should regulate the infusion at 42 gtt/minute to deliver the prescribed fluid challenge accurately. The other choices are incorrect as they do not reflect the correct calculation based on the given information.

3. A child with heart failure (HF) is taking digitalis. Which sign indicates to the nurse that the child may be experiencing digitalis toxicity?

• A. Tachycardia
• B. Dyspnea
• C. Vomiting
• D. Muscle cramps

Correct answer: C

Rationale: Vomiting is a common sign of digitalis toxicity and should be closely monitored. While tachycardia is a common sign of heart failure, it is not typically associated with digitalis toxicity (Choice A). Dyspnea (Choice B) and muscle cramps (Choice D) are not specific signs of digitalis toxicity and can be present in other conditions. Therefore, the presence of vomiting should raise concerns about digitalis toxicity in the child with heart failure.

4. 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.

5. A client with leukemia who is receiving myelosuppressive chemotherapy has a platelet count of 25,000/mm3. Which intervention is most important for the nurse to include in this client’s plan of care?

• A. Monitor for signs of activity intolerance
• B. Require visitors to wear respiratory masks
• C. Assess urine and stool for occult blood
• D. Obtain client’s temperature q4 hours

Correct answer: C

Rationale: The correct answer is to assess urine and stool for occult blood. With a low platelet count, there is an increased risk of bleeding. Monitoring for occult blood is essential to detect any signs of internal bleeding. Choices A, B, and D are not the priority interventions in this situation. While monitoring for signs of activity intolerance, requiring visitors to wear respiratory masks, and obtaining the client's temperature are important aspects of care, they are not as critical as assessing for occult blood in a client with a low platelet count.
