Nursing Elites

1. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.

2. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse's decision to hold the client's scheduled antihypertensive medication?

• A. Increased urinary clearance of the multiple medications has produced diuresis and lowered the blood pressure
• B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness
• C. The additive effect of multiple medications has caused the blood pressure to drop too low.
• D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.

Correct answer: C

Rationale: When medications with a similar action are administered, an additive effect occurs that is the sum of the effects of each medication. In this case, several medications that all lower blood pressure, when administered together, resulted in hypotension.

3. The nurse determines that a client's pupils constrict as they change focus from a far object. What documentation should the nurse enter about this finding?

• A. Pupils reactive to accommodation.
• B. Nystagmus present with pupillary focus.
• C. Peripheral vision intact.
• D. Consensual pupillary constriction present.

Correct answer: A

Rationale: The correct answer is A: 'Pupils reactive to accommodation.' When pupils constrict as the client changes focus from a far object to a near one, it indicates a normal response known as accommodation. This physiological process allows the eyes to adjust their focus, and it is a healthy finding. Choice B is incorrect because nystagmus is an involuntary eye movement, not related to the change in focus. Choice C is irrelevant to the scenario and does not describe the observed finding. Choice D refers to pupillary constriction in response to light, not accommodation to changes in focus.

4. A 59-year-old male client comes to the clinic and reports his concern over a lump that 'just popped up on my neck about a week ago.' In performing an examination of the lump, the nurse palpates a large, nontender, hardened left subclavian lymph node. There is no overlying tissue inflammation. What do these findings suggest?

• A. Malignancy
• B. Infection
• C. Benign cyst
• D. Lymphadenitis

Correct answer: A

Rationale: The correct answer is A: Malignancy. A large, non-tender, hardened lymph node is a typical sign of malignancy and warrants further investigation. Choice B (Infection) is incorrect because typically in infections, lymph nodes are tender and may show signs of inflammation. Choice C (Benign cyst) is incorrect as a benign cyst would usually present as a soft, mobile lump. Choice D (Lymphadenitis) is incorrect as lymphadenitis usually presents with tender and enlarged lymph nodes due to inflammation.

5. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which clinical finding is most concerning to the nurse?

• A. Kussmaul respirations
• B. Blood glucose level of 300 mg/dl
• C. Serum potassium of 3.2 mEq/L
• D. Positive urine ketones

Correct answer: C

Rationale: The correct answer is C: Serum potassium of 3.2 mEq/L. A low serum potassium level in a client with DKA is concerning due to the risk of cardiac arrhythmias. Kussmaul respirations (choice A) are a compensatory mechanism for metabolic acidosis in DKA. A blood glucose level of 300 mg/dl (choice B) is elevated but expected in DKA. Positive urine ketones (choice D) are a classic finding in DKA and not as concerning as low serum potassium.
