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 patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving?

• A. Blood pressure (BP) is less than 140/90 mm Hg.
• B. Patient reports decreased exertional dyspnea
• C. Heart rate is between 60 and 100 beats/minute
• D. Patient's chest x-ray indicates clear lung fields

Correct answer: B

Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.

3. Which of the following techniques can help to prevent skin irritation or breakdown around a tracheostomy site?

• A. Manage secretions by providing suction on a regular basis
• B. Cleanse the site daily with a mixture of povidone-iodine and water
• C. Avoid using tube ties to secure the tube
• D. None of the above

Correct answer: A

Rationale: Excess secretions from the tracheostomy tube can collect near the stomal opening and cause skin breakdown. Management of secretions through regular suctioning will keep the area clean and dry, minimizing skin irritation. Choice B, cleansing the site daily with povidone-iodine and water, is incorrect as it may lead to skin irritation due to the harshness of povidone-iodine. Choice C, avoiding tube ties to secure the tube, is also incorrect as securing the tube is essential for stability. Choice D, 'None of the above,' is incorrect as managing secretions through suctioning is crucial in preventing skin irritation.

4. Diabetic patients are more prone to ____________ than other people without this chronic disorder.

• A. infection
• B. increased oxygen saturation
• C. low fibrinogen
• D. constipation

Correct answer: A

Rationale: Diabetic patients are more prone to infection than other people without this chronic disorder. Diabetes weakens the immune system and impairs the body's ability to fight off infections, making individuals with diabetes more susceptible to various types of infections. Increased oxygen saturation, low fibrinogen, and constipation are not directly related to diabetes or the increased infection risk associated with the condition. Increased oxygen saturation is actually a positive health indicator, low fibrinogen levels are not a common issue in diabetes, and constipation is not a primary concern when comparing diabetic patients to others without the condition.

5. A patient is deciding whether they should take the live influenza vaccine (nasal spray) or the inactivated influenza vaccine (shot). The nurse reviews the client's history. Which condition would NOT contraindicate the nasal (live vaccine) route of administration?

• A. The patient takes long-term corticosteroids
• B. The patient is not feeling well today
• C. The patient is 55 years old
• D. The patient has young children

Correct answer: D

Rationale: The correct answer is that the patient has young children. Having young children is not a contraindication for the live influenza vaccine unless the children are immunocompromised, which is not mentioned. Choice A, the patient taking long-term corticosteroids, is a contraindication for the live vaccine due to potential immunosuppression. Choice B, the patient not feeling well today, is a general precaution for vaccination and not a contraindication specific to the live influenza vaccine. Choice C, the patient being 55 years old, is not a contraindication for the live vaccine unless there are other specific medical conditions present.
