Nursing Elites

1. A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?

• A. Start oxygen at 2 L/min
• B. Initiate cardiac monitoring
• C. Initiate seizure precautions
• D. Keep the patient on bed rest

Correct answer: B

Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.

2. 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.

3. A client with DM has an above-knee amputation because of severe peripheral vascular disease. Two days following surgery, when preparing the client for dinner, what is the nurse's primary responsibility?

• A. Check the client's serum glucose level
• B. Assist the client out of bed to the chair
• C. Place the client in a high-Fowler's position
• D. Ensure that the client's residual limb is elevated

Correct answer: A

Rationale: The correct answer is to check the client's serum glucose level. In a client with diabetes who just had surgery, monitoring the serum glucose level is crucial to ensure proper management of the condition. This helps in preventing complications related to blood sugar fluctuations. Assisting the client out of bed may be important but not the primary responsibility at this time. Placing the client in a high-Fowler's position or ensuring the residual limb is elevated are important interventions for comfort and circulation but are not the primary concern in this scenario.

4. Most water leaves the body by way of the:

• A. Lungs
• B. Intestines
• C. Skin
• D. Kidneys

Correct answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.

5. Select the criteria that is accurately paired with its indication of birth weight or gestational age.

• A. Low birth weight: The neonate's weight is less than 1,500 g at the time of delivery.
• B. Appropriate for gestational age: The neonate's weight ranges from the 10th to the 90th percentile.
• C. Large for gestational age: The neonate's weight is above the 99th percentile.
• D. Small for gestational age: The neonate's weight is below the 20th percentile.

Correct answer: B

Rationale: Appropriate for gestational age (AGA) indicates a neonate's weight ranging from the 10th to the 90th percentile. This range signifies that the baby's weight is within the normal range for their gestational age. Choices A, C, and D provide inaccurate information about the criteria and do not correctly correspond to the indicated birth weight or gestational age. Low birth weight typically refers to a weight below 2,500 g, large for gestational age above the 90th percentile, and small for gestational age below the 10th percentile.
