Nursing Elites

1. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

2. A physician orders a serum creatinine for a hospitalized client. The nurse should explain to the client and his family that this test:

• A. is normal if the level is 4.0 to 5.5 mg/dl.
• B. can be elevated with increased protein intake.
• C. is a better indicator of renal function than the BUN.
• D. reflects the fluid volume status of a person

Correct answer: C

Rationale: A serum creatinine level should be 0.7 to 1.5 mg/dl, and it does not vary with increased protein intake, so it is a better indicator of renal function than the BUN. Choice A is incorrect as a serum creatinine level of 4.0 to 5.5 mg/dl is not normal. Choice B is incorrect as serum creatinine is not affected by increased protein intake. Choice D is incorrect as serum creatinine primarily reflects renal function, not fluid volume status.

3. Teaching about the importance of avoiding foods high in potassium is most crucial for which client?

• A. a client receiving diuretic therapy
• B. a client with an ileostomy
• C. a client with metabolic alkalosis
• D. a client with renal disease

Correct answer: D

Rationale: Clients with renal disease are prone to hyperkalemia due to impaired kidney function, making it crucial for them to avoid foods high in potassium to prevent further complications. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk of hypokalemia. These individuals should actually consume foods high in potassium to replenish the electrolyte lost through diuresis, ileostomy output, or metabolic alkalosis.

4. A central venous pressure reading of 11cm/H(2)O of an IV of normal saline is determined by the nurse caring for the patient. The patient has a diagnosis of pericarditis. Which of the following is the most applicable?

• A. The patient has a condition of hypovolemia.
• B. Not enough fluid has been given to the patient.
• C. Pericarditis may cause pressures greater than 10cm/H(2)O with testing of CVP.
• D. The patient may have a condition of arteriosclerosis.

Correct answer: C

Rationale: A central venous pressure reading above 10cm/H(2)O may indicate a condition of pericarditis, as the inflammation and fluid accumulation around the heart can lead to elevated pressures. Choices A, B, and D are incorrect. Hypovolemia would typically result in lower CVP readings, not higher. Not enough fluid given would also lead to lower CVP levels. Arteriosclerosis is not directly related to CVP readings in the context of pericarditis.

5. A violation of a patient's confidentiality occurs if two nurses are discussing client information in which of the following scenarios?

• A. With a physical therapist treating the patient
• B. With a social worker planning for discharge
• C. With another nurse on duty to plan for break time
• D. In the hallway outside the patient's room

Correct answer: D

Rationale: The correct answer is 'In the hallway outside the patient's room.' Discussing client information in a public area like a hallway can potentially breach patient confidentiality as it increases the risk of unauthorized individuals overhearing sensitive information. Choices A, B, and C involve discussing client information with other healthcare professionals in appropriate settings, which are more likely to maintain patient confidentiality compared to discussing in a public space like a hallway. Option D is the correct choice because it highlights a scenario where patient information is at higher risk of exposure to unauthorized individuals, hence violating patient confidentiality.
