Nursing Elites

1. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?

• A. Apical heart rate of 60 beats/min
• B. Sweating across the forehead
• C. Poor sucking effort
• D. Respiratory rate of 30 breaths/min

Correct answer: A

Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.

2. The practical nurse administered carbidopa-levodopa to a client diagnosed with Parkinson's disease. Which outcome by the client would indicate a therapeutic response?

• A. Decreased blood pressure
• B. Lessening of tremors
• C. Increased salivation
• D. Increased attention span

Correct answer: B

Rationale: The correct answer is B: Lessening of tremors. Carbidopa-levodopa increases the amount of levodopa to the CNS, providing more dopamine to the brain. Increased dopamine levels help alleviate Parkinson's symptoms such as tremors, involuntary movements, and gait abnormalities. Choices A, C, and D are incorrect as carbidopa-levodopa is not expected to have a direct effect on blood pressure, salivation, or attention span in the context of treating Parkinson's disease.

3. A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client's history, the nurse determines the client has been self-administering St. John's wort, an herbal preparation, on the advice of a friend. What information is most significant about this finding?

• A. Wort can decrease plasma concentration of Cyclospora
• B. Wort can decrease plasma concentration of Tacrolimus
• C. Wort can decrease plasma concentration of Cyclosporine
• D. Wort can decrease plasma concentration of Mycophenolate

Correct answer: C

Rationale: The most significant information about the client self-administering St. John's wort, an herbal preparation, is that it can decrease the plasma concentration of Cyclosporine. St. John's wort is known to reduce the efficacy of Cyclosporine, which is a common immunosuppressant drug used to prevent transplant rejection. Choices A, B, and D are incorrect because St. John's wort does not affect the plasma concentration of Cyclospora, Tacrolimus, or Mycophenolate.

4. Escitalopram is prescribed for a 16-year-old adolescent client who is clinically depressed. Five days later, the parent tells the practical nurse (PN) that the drug is not working because their child is not feeling any better. Which explanation should the PN provide?

• A. It takes 1 to 4 weeks for antidepressant medications to become effective.
• B. The dosage may need to be increased; I will contact your health care provider.
• C. Depression is difficult to treat with drugs alone. Therapy sessions would enhance their effectiveness.
• D. Based on your child's response to this drug, the health care provider is reviewing your medication regimen.

Correct answer: A

Rationale: Antidepressant medications typically require 1 to 4 weeks to reach their full therapeutic effect. It is crucial to educate the family that during the initial week of treatment, the child may experience heightened anxiety. Therefore, it is important to wait for the medication to take its full course before assessing its effectiveness.

5. A client undergoing hemodialysis for chronic kidney disease is taking the medication erythropoietin. The nurse should reinforce instructions to explain for which reason this medication is prescribed?

• A. This drug prevents infections associated with dialysis.
• B. This drug prevents deep vein thrombosis in older clients.
• C. This drug helps stimulate the production of red blood cells.
• D. This drug helps balance the level of phosphorus in the body.

Correct answer: C

Rationale: Erythropoietin is prescribed to stimulate the production of red blood cells. Clients undergoing hemodialysis often develop anemia due to end-stage renal disease. Erythropoietin helps correct this anemia by stimulating red blood cell production. It is not used to prevent infections associated with dialysis, prevent deep vein thrombosis, or balance phosphorus levels in the body.
