Nursing Elites

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. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

3. The nurse is assessing a client who has a new cast on the left arm. Which finding should the nurse report to the healthcare provider immediately?

• A. Client reports itching under the cast
• B. Client reports pain at the cast site
• C. Client reports swelling of the fingers
• D. Client reports warmth over the casted area

Correct answer: C

Rationale: Swelling of the fingers can indicate compromised circulation, which is a serious concern in a client with a new cast. It could suggest the development of compartment syndrome, a condition where increased pressure within the muscles can lead to impaired blood flow. This can result in tissue damage and should be addressed promptly. Itching under the cast, pain at the cast site, and warmth over the casted area are common findings after cast application and may not necessarily indicate an urgent issue requiring immediate reporting to the healthcare provider.

4. What assessment technique should the nurse use to monitor a client for a common untoward effect of phenytoin (Dilantin)?

• A. Bladder palpation
• B. Inspection of the mouth
• C. Blood glucose monitoring
• D. Auscultation of breath sounds

Correct answer: B

Rationale: The correct answer is B: Inspection of the mouth. This assessment technique is crucial for monitoring gingival hyperplasia, a common side effect of phenytoin. Bladder palpation (choice A) is not relevant to monitoring for phenytoin's side effects. Blood glucose monitoring (choice C) is important for clients with diabetes but is not specifically related to phenytoin. Auscultation of breath sounds (choice D) is more relevant for assessing respiratory conditions, not side effects of phenytoin.

5. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.
