Nursing Elites

1. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

2. A charge nurse notices that two staff nurses are not taking meal breaks during their shifts. Which of the following actions should the nurse take first?

• A. Discuss time management strategies with the nurses
• B. Provide coverage for the nurses' breaks
• C. Determine the reasons the nurses are not taking scheduled breaks
• D. Review policies for taking scheduled breaks

Correct answer: C

Rationale: The correct answer is to determine the reasons the nurses are not taking scheduled breaks. This action is crucial as it allows the charge nurse to understand the underlying causes for the behavior. By identifying the reasons, the nurse can then address the root of the issue effectively. Option A is incorrect because discussing time management strategies may not address the specific reasons for not taking breaks. Option B is incorrect as providing coverage for breaks does not address the underlying cause of the issue. Option D is also incorrect as reviewing policies should come after understanding the reasons for the behavior.

3. A client is in DKA, secondary to infection. As the condition progresses, which of the following symptoms might the nurse see?

• A. Kussmaul's respirations and a fruity odor on the breath
• B. Shallow respirations and severe abdominal pain
• C. Decreased respirations and increased urine output
• D. Cheyne-Stokes respirations and foul-smelling urine

Correct answer: A

Rationale: In diabetic ketoacidosis (DKA), as the condition progresses, the body tries to compensate for the acidic environment by increasing the respiratory rate, leading to Kussmaul's respirations. The accumulation of ketones in the body causes a fruity odor on the breath. Option A is correct because Kussmaul's respirations and a fruity odor on the breath are classic signs of DKA. Option B is incorrect because shallow respirations are not typically seen in DKA, and severe abdominal pain is more commonly associated with conditions like pancreatitis. Option C is incorrect as decreased respirations are not a typical finding in DKA, and increased urine output is more commonly seen in conditions like diabetes insipidus. Option D is incorrect because Cheyne-Stokes respirations are not characteristic of DKA, and foul-smelling urine is not a prominent symptom in this condition.

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.
