1. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

2. A client is brought into the emergency department after finishing a course of antibiotics for a urinary tract infection. The client is experiencing dyspnea, chest tightness, and agitation. Her blood pressure is 88/58, she has generalized hives over her body, and her lips and tongue are swollen. After the nurse calls for help, what is the next appropriate action?

• A. Start an IV and administer a 1-liter bolus of Lactated Ringer's solution
• B. Administer 0.3 mg of 1:1000 epinephrine IM
• C. Administer 15 mg diphenhydramine IM
• D. Monitor the client until help arrives

Correct answer: B

Rationale: A client experiencing an anaphylactic reaction will likely present with rash or hives, swelling of the lips, face, or tongue, hypotension, or dyspnea. In this scenario, the client is showing signs of anaphylaxis with dyspnea, chest tightness, hives, hypotension, and swelling of the lips and tongue. The next appropriate action would be to administer 0.3 mg of 1:1000 epinephrine intramuscularly. Epinephrine helps relax the muscles of the airway, improve breathing, and increase oxygenation, which is crucial in managing anaphylaxis. Starting an IV and administering fluids can be important but not the immediate priority. Diphenhydramine may be used as an adjunct therapy but should not delay the administration of epinephrine in the acute phase of anaphylaxis. Monitoring the client without providing immediate treatment can lead to a worsening of the anaphylactic reaction, potentially resulting in a life-threatening situation.

3. What intervention should the nurse implement while a client is having a grand mal seizure?

• A. Open the jaw and place a bite block between the teeth
• B. Try to place the client on his side
• C. Restrain the client to prevent injury
• D. Place pillows around the client

Correct answer: B

Rationale: During a grand mal seizure, the client is at risk of injury due to severe, involuntary muscle spasms and contractions. It is crucial for the nurse to avoid restraining the client or inserting objects into their mouth, as these actions may lead to further harm. Placing the client on their side can help facilitate the drainage of oral secretions and assist in maintaining an open airway, reducing the risk of aspiration. Restraint should be avoided as it can exacerbate muscle contractions and increase the risk of injury. Placing pillows around the client may not provide adequate support or protection during the seizure, making it a less effective intervention compared to positioning the client on their side.

4. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.

5. A 7-year-old child is seen in a clinic, and the pediatrician documents a diagnosis of nighttime (nocturnal) enuresis. What information should the nurse provide to the parents?

• A. Nighttime (nocturnal) enuresis does not respond to treatment.
• B. Nighttime (nocturnal) enuresis is caused by a psychiatric problem.
• C. Nighttime (nocturnal) enuresis requires surgical intervention to improve the problem.
• D. Nighttime (nocturnal) enuresis is usually outgrown without therapeutic intervention.

Correct answer: D

Rationale: Nighttime (nocturnal) enuresis is common in children and is characterized by a child who has never been dry at night for extended periods. Most children eventually outgrow bedwetting without therapeutic intervention. This condition is due to the child being unable to sense a full bladder and not awakening to void, often related to delayed maturation of the central nervous system. It is important for parents to understand that nighttime (nocturnal) enuresis is not caused by a psychiatric problem, does not typically require surgical intervention, and usually resolves on its own over time.
