Nursing Elites

1. A charge nurse is observing a newly licensed nurse prepare a sterile field. Which of the following actions should the charge nurse identify as contaminating the sterile field?

• A. The nurse opens the sterile field on a wet surface.
• B. The nurse turns away from the sterile field.
• C. The nurse uses a non-sterile glove to touch the sterile field.
• D. The nurse touches the edge of the sterile drape with her hand.

Correct answer: A

Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.

2. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?

• A. Decreased calcium
• B. Elevated potassium
• C. Increased sodium
• D. Low hemoglobin

Correct answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

3. During a peripheral vascular assessment, a healthcare professional places the bell of the stethoscope on a client's neck and hears an audible vascular sound associated with turbulent blood flow. This sound indicates which of the following?

• A. Narrowed arterial lumen
• B. Distended jugular veins
• C. Impaired ventricular contraction
• D. Asynchronous closure of the aortic and pulmonic valve

Correct answer: A

Rationale: The correct answer is A: Narrowed arterial lumen. Arterial bruits are abnormal sounds caused by turbulent blood flow through narrowed or occluded arteries. This turbulent flow creates a blowing sound, which is heard as an arterial bruit. Distended jugular veins (choice B) are typically associated with venous issues, not arterial abnormalities. Impaired ventricular contraction (choice C) and asynchronous closure of the aortic and pulmonic valve (choice D) are not directly related to the audible vascular sound described in the scenario.

4. A mother of a child with a neural tube defect asks the nurse what she can do to decrease the chances of having another baby with a neural tube defect. What is the best response by the nurse?

• A. Folic acid should be taken before and after conception.
• B. Multivitamin supplements are recommended during pregnancy.
• C. A well-balanced diet promotes normal fetal development.
• D. Increased dietary iron improves the health of mother and fetus.

Correct answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

5. The nurse admits a 7 year-old to the emergency room after a leg injury. The x-rays show a femur fracture near the epiphysis. The parents ask what will be the outcome of this injury. The appropriate response by the nurse should be which of these statements?

• A. The injury is expected to heal quickly because of thin periosteum.
• B. In some instances the result is a retarded bone growth.
• C. Bone growth is stimulated in the affected leg.
• D. This type of injury shows more rapid union than that of younger children.

Correct answer: B

Rationale: A fracture near the epiphysis can result in retarded bone growth, so this should be communicated to the parents.
