Nursing Elites

1. A two-year-old child has sustained an injury to the leg and refuses to walk. The nurse in the emergency department documents swelling of the lower affected leg. Which of the following does the nurse suspect is the cause of the child's symptoms?

• A. Possible fracture of the tibia.
• B. Bruising of the gastrocnemius muscle.
• C. Possible fracture of the radius.
• D. No anatomic injury, the child wants his mother to carry him.

Correct answer: A

Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.

2. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:

• A. Assist the client in using the bedside commode
• B. Administer stool softeners daily as prescribed
• C. Administer antidysrhythmics PRN as prescribed
• D. Maintain the client on strict bed rest

Correct answer: B

Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.

3. A nursing student caring for a 6-month-old infant is asked to collect a sample for urinalysis from the infant. How should the student collect the specimen?

• A. Catheterizing the infant using the smallest available Foley catheter
• B. Attaching a urinary collection device to the infant's perineum for collection
• C. Obtaining the specimen from the diaper by squeezing the diaper after the infant voids
• D. Noting the time of the next expected voiding and then preparing a specimen cup for the urine

Correct answer: B

Rationale: The correct method for collecting a urine sample from an infant for urinalysis is by attaching a urinary collection device to the infant's perineum. This device is a plastic bag with an adhesive opening that allows it to be secured to the perineum to collect urine. Catheterizing the infant with a Foley catheter should not be done unless specifically prescribed due to the risk of infection. Obtaining the specimen from the diaper by squeezing it after the infant voids may not provide an accurate sample for urinalysis. Trying to predict the time of the next voiding to prepare a specimen cup is not practical or reliable in ensuring an appropriate sample for urinalysis.

4. 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.

5. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:

• A. Lack of thirst
• B. Pale skin
• C. Hypertension
• D. Swollen tongue

Correct answer: D

Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.
