Nursing Elites

1. A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. The client weighs 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.

2. A healthcare professional is reviewing the laboratory results of a client who is receiving chemotherapy. Which of the following findings should the healthcare professional report immediately?

• A. White blood cell count of 4,500/mm³
• B. Hemoglobin level of 8 g/dL
• C. Platelet count of 90,000/mm³
• D. Serum potassium level of 3.5 mEq/L

Correct answer: C

Rationale: A platelet count of 90,000/mm³ indicates thrombocytopenia, which increases the risk of bleeding and requires immediate intervention. Thrombocytopenia can lead to serious bleeding complications, so it is crucial to address this finding promptly. A low white blood cell count (choice A) may indicate neutropenia but is not as immediately life-threatening as severe thrombocytopenia. A hemoglobin level of 8 g/dL (choice B) would require intervention but is not as urgent as addressing a critically low platelet count. A serum potassium level of 3.5 mEq/L (choice D) is on the lower side of normal but does not pose an immediate risk to the client's safety compared to severe thrombocytopenia.

3. Which assessment finding is most concerning in a patient receiving morphine?

• A. Hypotension
• B. Bradycardia
• C. Respiratory depression
• D. Hypertension

Correct answer: C

Rationale: The correct answer is C, respiratory depression. When a patient is receiving morphine, respiratory depression is the most concerning side effect because it can lead to serious complications, including respiratory arrest and even death. Monitoring the patient's respiratory status is crucial to ensure early detection of any signs of respiratory depression. Choices A, B, and D are incorrect because although hypotension, bradycardia, and hypertension can occur as side effects of morphine, they are not as immediately life-threatening as respiratory depression in this context.

4. A client has a new prescription for metformin. Which of the following client statements indicates an understanding of the teaching?

• A. ''I will take this medication at bedtime to avoid nausea.''
• B. ''I should take this medication with a full glass of water in the morning.''
• C. ''I should avoid eating foods that contain iodine.''
• D. ''I should take this medication with food to improve absorption.''

Correct answer: B

Rationale: The correct answer is B. Metformin should be taken with a full glass of water in the morning to improve absorption and prevent gastrointestinal upset. Choice A is incorrect because metformin is not typically taken at bedtime. Choice C is unrelated to metformin therapy. Choice D is incorrect because metformin is actually better absorbed when taken with or after meals.

5. A nurse is caring for a child who has cystic fibrosis and is receiving postural drainage. Which of the following actions should the nurse take?

• A. Perform the procedure after meals.
• B. Administer bronchodilators before the procedure.
• C. Hold hand flat to perform percussion.
• D. Perform the procedure twice a day.

Correct answer: C

Rationale: The correct action the nurse should take when caring for a child with cystic fibrosis receiving postural drainage is to hold the hand flat to perform percussion. This technique allows for effective chest physiotherapy. Choice A is incorrect because postural drainage should be performed before meals to prevent vomiting during the procedure. Choice B is incorrect because bronchodilators are typically administered before postural drainage to help open up the airways. Choice D is incorrect as the frequency of postural drainage may vary depending on the individual's condition, so performing it twice a day may not be appropriate for all patients.
