Nursing Elites

1. 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.

2. A client is admitted to the emergency department with symptoms of arm numbness, chest pain, and nausea/vomiting. The examining healthcare provider believes that the client has experienced an acute myocardial infarction (AMI) within the past three hours and would like to initiate tissue plasminogen activator (tPA) therapy. Which client history findings contraindicate the use of tPA?

• A. Treats hypoglycemia with an oral hypoglycemic agent.
• B. Had a cerebrovascular hemorrhage 2 months ago.
• C. Current age 65, father died of MI at 55.
• D. Report of being intolerant of medication that contains aspirin.

Correct answer: B

Rationale: A history of cerebrovascular hemorrhage is a contraindication for tPA therapy due to the risk of bleeding. Choice A is incorrect because treating hypoglycemia with an oral hypoglycemic agent is not a contraindication for tPA therapy. Choice C is incorrect as age and family history of MI do not contraindicate the use of tPA. Choice D is incorrect as being intolerant of medication containing aspirin is not a contraindication for tPA therapy.

3. 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.

4. Which is a long-term complication of cleft lip and palate?

• A. Cognitive impairment
• B. Altered growth and development
• C. Faulty dentition
• D. Physical abilities

Correct answer: C

Rationale: The correct answer is C, 'Faulty dentition.' The older child with cleft lip and palate may experience psychological difficulties due to the cosmetic appearance of the defect, issues with impaired speech, and faulty dentition. This can lead to problems with dental alignment, crowding, missing or malformed teeth, and other dental issues. Choices A, B, and D are incorrect as cognitive impairment, altered growth and development, and physical abilities are not typically considered long-term complications of cleft lip and palate.

5. What are the clinical manifestations of otitis media?

• A. Earache, wheezing, vomiting
• B. Coughing, rhinorrhea, headache
• C. Fever, irritability, pulling on ear
• D. Wheezing, cough, drainage in ear canal

Correct answer: C

Rationale: The correct answer is C: Fever, irritability, pulling on the ear. Clinical manifestations of otitis media commonly include fever, irritability, and children may show signs of pulling or rubbing their ears. Choices A, B, and D are incorrect. Choice A includes wheezing and vomiting, which are not typical symptoms of otitis media. Choice B includes coughing, rhinorrhea, and headache, which are more commonly associated with upper respiratory infections rather than otitis media. Choice D includes wheezing, cough, and drainage in the ear canal, which are not typical clinical manifestations of otitis media.
