Nursing Elites

1. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?

• A. Ca
• B. K
• C. Na
• D. Cl

Correct answer: B

Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.

2. A patient has a history of cardiac arrhythmia. A nurse has been ordered to give 2 units of blood to this patient. The nurse should take which of the following actions?

• A. Administer pain medication to the patient.
• B. Inform the patient's family about the procedure in person.
• C. Decrease the temperature of the blood to be given.
• D. Increase the temperature of the blood to be given.

Correct answer: D

Rationale: In patients with a history of cardiac arrhythmia, warming the blood before transfusion can help prevent additional arrhythmias. Cold blood can lead to arrhythmias and should be avoided. Administering pain medication (Choice A) is not directly related to the safe administration of blood. Informing the patient's family in person (Choice B) is important but not the immediate action required for safe transfusion. Decreasing the temperature of the blood to be given (Choice C) would increase the risk of cardiac arrhythmia, contrary to the goal of ensuring patient safety.

3. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.

4. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?

• A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
• B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
• C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
• D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.

Correct answer: A

Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.

5. The client with chronic pancreatitis should be taught how to monitor for which of the following possible additional problems associated with pancreatic disease?

• A. Hypertension
• B. Diabetes
• C. Hypothyroidism
• D. Graves' disease

Correct answer: B

Rationale: The correct answer is diabetes. In chronic pancreatitis, the pancreas may become unable to produce sufficient insulin, leading to diabetes. This connection underscores the importance of monitoring blood sugar levels and understanding the signs and symptoms of diabetes in clients with chronic pancreatitis. Choice A, hypertension, is not directly associated with pancreatic disease but rather with cardiovascular health. Choice C, hypothyroidism, and Choice D, Graves' disease, are unrelated to pancreatic disease and are endocrine disorders affecting the thyroid gland.
