Nursing Elites

1. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

2. A 35-year-old female client has just been admitted to the post-anesthesia recovery unit following a partial thyroidectomy. Which statement reflects the nurse's accurate understanding of the expected outcome for the client following this surgery?

• A. Supplemental hormonal therapy will probably be unnecessary.
• B. The thyroid will regenerate to a normal size within a few years.
• C. The client will be restricted from eating seafood.
• D. The remainder of the thyroid will be removed at a later date.

Correct answer: C

Rationale: After a partial thyroidectomy, the client may be advised to avoid eating seafood due to its high iodine content, which can affect the thyroid function. Choice A is incorrect because after a partial thyroidectomy, supplemental hormonal therapy may be necessary. Choice B is incorrect as the thyroid does not regenerate after a partial thyroidectomy. Choice D is incorrect; the remaining portion of the thyroid is not typically removed at a later date unless there are specific medical reasons to do so.

3. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

4. A male client reports the onset of numbness and tingling in his fingers and around his mouth. Which lab test is important for the nurse to review before contacting the healthcare provider?

• A. Capillary glucose
• B. Urine specific gravity
• C. Serum calcium
• D. White blood cell count

Correct answer: C

Rationale: The correct answer is C: Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia. Serum calcium levels should be reviewed as they play a crucial role in diagnosing and managing hypocalcemia. Option A, capillary glucose, is not relevant to the symptoms described. Option B, urine specific gravity, is not typically used to assess numbness and tingling. Option D, white blood cell count, is unrelated to the symptoms presented by the client.

5. A client with end-stage renal disease (ESRD is scheduled for hemodialysis. Which laboratory value should the nurse monitor closely before the procedure?

• A. Serum creatinine
• B. Serum potassium
• C. Serum sodium
• D. Hemoglobin

Correct answer: B

Rationale: Before hemodialysis in a client with end-stage renal disease (ESRD), monitoring serum potassium closely is crucial. ESRD patients are at risk of hyperkalemia, which can lead to severe cardiac complications. Checking serum potassium levels helps in assessing and managing this electrolyte imbalance. Serum creatinine (Choice A) is a marker of kidney function but is not the most critical value to monitor before hemodialysis. Serum sodium (Choice C) may be affected in renal disease, but potassium is a more crucial electrolyte to monitor. Hemoglobin (Choice D) is essential for assessing anemia in ESRD but is not the primary focus before hemodialysis.
