1. A client is receiving a low dose of dopamine (Intropin) IV for the treatment of hypotension. Which indicator reflects that the medication is having the desired effect?
- A. Increased heart rate
- B. Increased urinary output
- C. Increased blood pressure
- D. Increased respiratory rate
Correct answer: C
Rationale: Increased blood pressure is the desired effect of administering dopamine (Intropin) to treat hypotension. Dopamine acts by stimulating adrenergic receptors, leading to vasoconstriction and increased cardiac output. This results in an elevation of blood pressure. Choices A, B, and D are incorrect as they do not directly reflect the therapeutic action of dopamine in treating hypotension. Increased heart rate may indicate the body compensating for low blood pressure, increased urinary output is more related to kidney function, and increased respiratory rate is often seen in response to respiratory issues, not the action of dopamine on hypotension.
2. A 9-year-old boy with tetralogy of Fallot is being discharged following a cardiac catheterization. Which discharge instruction should the nurse provide the parents?
- A. Do not allow the child to return to school for at least one month
- B. Notify the healthcare provider if there is any drainage at the catheterization site
- C. Monitor the child's temperature and report any elevation
- D. Observe for any changes in the child's color or energy level
Correct answer: B
Rationale: The correct answer is to notify the healthcare provider if there is any drainage at the catheterization site. Drainage at the site can be a sign of infection, which needs prompt evaluation and treatment. Choices A, C, and D are not as crucial as identifying and reporting any drainage, which is more directly related to potential complications post-cardiac catheterization.
3. The nurse assesses a client who is receiving an infusion of 5% dextrose in water with 20 mEq of potassium chloride. The client has oliguria and a serum potassium level of 6.5 mEq/L. What action should the nurse implement first?
- A. Notify the healthcare provider of the laboratory results
- B. Decrease the rate of the IV infusion
- C. Stop the infusion
- D. Administer sodium polystyrene sulfonate (Kayexalate)
Correct answer: C
Rationale: The correct action for the nurse to implement first is to stop the infusion. Stopping the infusion is crucial to prevent further potassium from being administered, which can exacerbate the client's hyperkalemia. Notifying the healthcare provider of the laboratory results (Choice A) can be done after taking immediate action to stop the infusion. Decreasing the rate of the IV infusion (Choice B) may not be sufficient to address the high potassium level quickly. Administering sodium polystyrene sulfonate (Kayexalate) (Choice D) is not the initial action for managing hyperkalemia; stopping the potassium infusion takes precedence.
4. A client with diabetes mellitus reports feeling dizzy and has a blood glucose level of 50 mg/dl. What action should the nurse take first?
- A. Administer 1 mg of glucagon intramuscularly
- B. Provide 15 grams of carbohydrate
- C. Check the client's blood pressure
- D. Notify the healthcare provider
Correct answer: B
Rationale: Providing 15 grams of carbohydrate is the initial action to treat hypoglycemia. When a client with diabetes mellitus experiences symptoms of hypoglycemia, such as dizziness and with a blood glucose level of 50 mg/dl, the immediate priority is to raise their blood sugar levels quickly. Administering carbohydrates, such as fruit juice or glucose tablets, is the recommended first step to reverse hypoglycemia. Administering glucagon intramuscularly is usually reserved for severe hypoglycemia when the client is unconscious or unable to swallow. Checking the client's blood pressure is important but not the primary intervention for hypoglycemia. Notifying the healthcare provider can be done after the immediate management of hypoglycemia.
5. The nurse is preparing to administer an IM injection to a 6-month-old child. Which injection site is best for the nurse to use?
- A. Vastus lateralis
- B. Deltoid
- C. Ventrogluteal
- D. Dorsogluteal
Correct answer: A
Rationale: The vastus lateralis is the preferred site for IM injections in infants due to muscle development. In infants under 1 year old, the vastus lateralis muscle in the thigh is often used for IM injections due to its size and development. The deltoid muscle is typically used for adults, and the ventrogluteal and dorsogluteal sites are more commonly used for older children and adults. Therefore, the best choice for administering an IM injection to a 6-month-old child is the vastus lateralis.
