Nursing Elites

1. What most influences the severity of respiratory distress syndrome (RDS)?

• A. Poor cough and gag reflex
• B. The gestational age at birth
• C. Administering high concentrations of oxygen
• D. The sex of the infant

Correct answer: B

Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.

2. A client with a history of seizures is prescribed phenytoin. Which side effect should the nurse instruct the client to report?

• A. Drowsiness
• B. Gingival hyperplasia
• C. Weight gain
• D. Blurred vision

Correct answer: B

Rationale: The correct answer is B: Gingival hyperplasia. Phenytoin is known to cause gingival hyperplasia, which is an overgrowth of gum tissue. This side effect is important to report to the healthcare provider because it can lead to oral health problems. Choice A, drowsiness, is a common side effect of many antiepileptic drugs but is not specific to phenytoin. Choice C, weight gain, is not a typical side effect of phenytoin. Choice D, blurred vision, is not a common side effect of phenytoin; it is more commonly associated with other medications.

3. During the initial assessment of an older male client with obesity and diabetes who develops intermittent claudication, which additional information obtained by the nurse is most significant?

• A. Smokes 1.5 packs of cigarettes daily.
• B. Exercises regularly.
• C. Has a high-fat diet.
• D. Consumes alcohol daily.

Correct answer: A

Rationale: The correct answer is A: 'Smokes 1.5 packs of cigarettes daily.' Smoking is a significant risk factor for peripheral arterial disease, a condition that can lead to intermittent claudication. The nicotine and other chemicals in cigarettes can damage blood vessels, leading to reduced blood flow and increased risk of developing circulation problems. Choices B, C, and D are less significant in the context of intermittent claudication. Regular exercise, a high-fat diet, and daily alcohol consumption may have health implications, but they are not as directly linked to the development of intermittent claudication in the presence of obesity, diabetes, and smoking.

4. 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.

5. In planning nursing care for a bedfast client, which factor is most likely to contribute to the development of deep vein thrombosis (DVT) in an immobile client?

• A. Atherosclerotic plaque formation.
• B. Stasis of blood flow.
• C. Endothelial damage.
• D. Atherosclerotic vessel changes.

Correct answer: B

Rationale: The correct answer is B: Stasis of blood flow. Stasis of blood flow in immobile clients increases the risk of DVT, as lack of movement can cause blood to pool and clot. Atherosclerotic plaque formation (choice A) and atherosclerotic vessel changes (choice D) are more related to arterial diseases rather than DVT. Endothelial damage (choice C) can contribute to the development of DVT, but in an immobile client, stasis of blood flow is the most significant factor.
