A healthcare professional is reviewing a client's laboratory report and notes that the serum calcium level is 4.0 mg/dL. The healthcare professional understands that which condition most likely caused this serum calcium level?
- A. Prolonged bed rest
- B. Renal insufficiency
- C. Hyperparathyroidism
- D. Excessive ingestion of vitamin D
Correct Answer: A
Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.

A nurse working on a med-surg unit is managing the care of four clients. The nurse should schedule an interdisciplinary conference for which of the following clients?
- A. A client who is at risk for pressure ulcers and has an albumin level of 4.2 g/dL
- B. A client with type 1 DM who uses an insulin pump
- C. A client who is receiving heparin and has an aPTT of 34 seconds
- D. A client with orthostatic hypotension receiving IV fluids
Correct Answer: C
Rationale: The nurse should schedule an interdisciplinary conference for a client who is receiving heparin and has an aPTT of 34 seconds to ensure comprehensive care coordination. In this case, the need for a conference may be to discuss potential adjustments in heparin therapy, monitor for adverse effects, or ensure proper anticoagulation levels. Choices A, B, and D do not specifically indicate the need for interdisciplinary collaboration related to the client's condition or treatment. Therefore, they are not the priority for scheduling an interdisciplinary conference.
Your patient has a blood potassium level of 9.2 mEq/L. What intervention should you anticipate for this patient?
- A. Intravenous potassium supplementation
- B. Intravenous calcium supplementation
- C. Kidney dialysis
- D. Parenteral nutrition
Correct Answer: C
Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.
Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:
- A. 1 in 85 births.
- B. 1 in 5400 births.
- C. 1 in 2700 births.
- D. 1 in 540 births
Correct Answer: A
Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
The doctor has ordered 20 cc per hour of normal saline intravenously for your pediatric patient. You will be using pediatric intravenous tubing that delivers 60 cc per drop. How many drops per minute will you administer using this pediatric intravenous set?
- A. 30 drops per minute
- B. 25 drops per minute
- C. 20 drops per minute
- D. 22 drops per minute
Correct Answer: C
Rationale: To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour. To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute. Therefore, the correct answer is 20 drops per minute. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.
