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.

A client with diabetes mellitus reports feeling shaky and has a blood glucose level of 60 mg/dl. What action should the nurse take?

• A. Administer 15 grams of carbohydrate
• B. Administer a glucagon injection
• C. Provide a snack with protein
• D. Encourage the client to rest

Correct Answer: A
Rationale: In the scenario described, the client is experiencing hypoglycemia with a blood glucose level of 60 mg/dl. The appropriate action for the nurse to take is to administer 15 grams of carbohydrate. Carbohydrate intake helps to rapidly raise blood sugar levels in cases of hypoglycemia. Administering a glucagon injection (Choice B) is not the initial treatment for mild hypoglycemia; it is typically used for severe hypoglycemia when the client is unable to consume oral carbohydrates. Providing a snack with protein (Choice C) is not the first-line intervention for hypoglycemia; immediate carbohydrate intake is necessary to raise blood sugar levels quickly. Encouraging the client to rest (Choice D) may be appropriate after administering the carbohydrate, but the priority is to address the low blood glucose levels by administering carbohydrates first.

A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client reports difficulty breathing. What action should the nurse take first?

• A. Increase the oxygen flow rate
• B. Instruct the client to breathe deeply and cough
• C. Check the client's oxygen saturation level
• D. Place the client in a high-Fowler's position

Correct Answer: C
Rationale: The correct action for the nurse to take first when a client with COPD reports difficulty breathing while receiving oxygen is to check the client's oxygen saturation level. This helps in determining the adequacy of oxygenation and identifying the cause of the breathing difficulty. Increasing the oxygen flow rate (Choice A) may not be appropriate without knowing the current oxygen saturation level. Instructing the client to breathe deeply and cough (Choice B) may not address the immediate need for oxygen assessment. Placing the client in a high-Fowler's position (Choice D) can help with breathing but should come after ensuring proper oxygenation.

When evaluating the preoperative teaching of a client scheduled for arthroscopic anterior cruciate ligament repair, which statement by the client indicates that the teaching was effective?

• A. I will use crutches to keep my weight off my knee
• B. I will stay home until a wheelchair is delivered
• C. I can use the trapeze bar and side rails on the bed to help me turn regularly
• D. I can put my full weight on my foot starting the day after surgery

Correct Answer: A
Rationale: The correct answer is A. Using crutches indicates an understanding of weight-bearing restrictions post-surgery. Choice B is incorrect because waiting for a wheelchair is not related to postoperative mobility instructions. Choice C is incorrect as turning in bed using the trapeze bar and side rails does not address weight-bearing restrictions. Choice D is incorrect because putting full weight on the foot immediately after surgery contradicts the need to keep weight off the knee.

The healthcare provider is caring for a client with jaundice. Which serum laboratory value is likely to be elevated for this client?

• A. Amylase
• B. Creatinine
• C. Blood urea nitrogen
• D. Bilirubin

Correct Answer: D
Rationale: Bilirubin is a key serum laboratory value that is likely to be elevated in clients with jaundice. Jaundice is characterized by a yellowish discoloration of the skin and eyes due to an excess of bilirubin, a breakdown product of hemoglobin. Elevated amylase levels are associated with pancreatic conditions, not specifically jaundice. Creatinine and blood urea nitrogen are markers of kidney function and are not directly related to jaundice.
