Nursing Elites

1. The health care provider writes an order for bacteriologic testing for a patient who has a positive tuberculosis skin test. Which action should the nurse take?

• A. Teach about the reason for the blood tests.
• B. Schedule an appointment for a chest x-ray.
• C. Teach about the need to get sputum specimens for 2 to 3 consecutive days.
• D. Instruct the patient to expectorate three specimens as soon as possible.

Correct answer: C

Rationale: The correct action for the nurse to take is to teach the patient about the need to collect sputum specimens for 2 to 3 consecutive days for bacteriologic testing for M. tuberculosis. It is important to obtain these specimens on different days rather than all at once. Blood tests are not used for tuberculosis testing, so teaching about blood tests is not relevant. While a chest x-ray is important in tuberculosis diagnosis, it is not a bacteriologic test. The appearance on a chest x-ray alone is not sufficient to diagnose TB as other diseases can have similar findings.

2. What is the priority nursing diagnosis for a patient experiencing a migraine headache?

• A. Acute pain related to biologic and chemical factors
• B. Anxiety related to change in or threat to health status
• C. Hopelessness related to deteriorating physiological condition
• D. Risk for side effects related to medical therapy

Correct answer: A

Rationale: The priority nursing diagnosis for a patient experiencing a migraine headache is 'Acute pain related to biologic and chemical factors.' Migraine headaches are characterized by severe throbbing pain, often accompanied by sensitivity to light and sound. Addressing the acute pain is crucial to improve the patient's comfort and quality of life. Choices B, C, and D are not the priority nursing diagnoses for a patient with a migraine headache. Anxiety, hopelessness, and risk for side effects may not be as urgent as managing the acute pain associated with a migraine.

3. A client is admitted for a head injury. His body is lying in an abnormal position and the physician states he is exhibiting decorticate posturing. Based on this assessment, the nurse can expect to find the client with:

• A. The legs extended and rotated internally; the elbow, wrists, and fingers flexed
• B. The legs pulled toward the chest; the head bent back at a 30-degree angle
• C. The back arched; the arms and legs extended and rigid
• D. The legs extended and rotated externally; the head turned to the right or the left

Correct answer: A

Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.

4. A nurse admits a 3-week-old infant to the special care nursery with a diagnosis of bronchopulmonary dysplasia. As the nurse reviews the birth history, which data would be most consistent with this diagnosis?

• A. Gestational age assessment suggested growth retardation
• B. Meconium was cleared from the airway at delivery
• C. Phototherapy was used to treat Rh incompatibility
• D. The infant received mechanical ventilation for 2 weeks

Correct answer: D

Rationale: The correct answer is 'The infant received mechanical ventilation for 2 weeks.' Bronchopulmonary dysplasia is a condition primarily caused by therapies like positive-pressure ventilation used in the treatment of lung disease. This leads to lung damage and subsequent respiratory problems. Choices A, B, and C are not consistent with the diagnosis of bronchopulmonary dysplasia. Gestational age assessment suggesting growth retardation is more indicative of intrauterine growth restriction, clearing meconium from the airway at delivery is related to potential respiratory issues at birth, and phototherapy for Rh incompatibility is unrelated to bronchopulmonary dysplasia.

5. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?

• A. IgA
• B. IgD
• C. IgE
• D. IgG

Correct answer: D

Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.
