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. The nurse is performing tuberculosis (TB) skin tests in a clinic that has many patients who have immigrated to the United States. Which question is most important for the nurse to ask before the skin test?

• A. Is there any family history of TB?
• B. How long have you lived in the United States?
• C. Do you take any over-the-counter (OTC) medications?
• D. Have you received the bacille Calmette-Guerin (BCG) vaccine for TB?

Correct answer: D

Rationale: It is crucial for the nurse to inquire about whether the patient has received the bacille Calmette-Guerin (BCG) vaccine for TB before performing the skin test. Patients who have received the BCG vaccine can have a positive Mantoux test, leading to the need for alternative screening methods, such as a chest x-ray, to determine TB infection. While family history of TB and length of time in the United States are relevant factors, they do not directly impact the decision to perform the TB skin test. Asking about over-the-counter medications, unless relevant to TB treatment, is not as critical as assessing BCG vaccination status.

3. A patient in the emergency room has a fractured left elbow and presents with an unequal radial pulse, swelling, and numbness in the left hand after waiting for 5 hours. What is the nurse's priority intervention?

• A. Place the patient in a supine position
• B. Ask the patient to rate his pain on a scale of 1 to 10.
• C. Wrap the fractured area with a snug dressing
• D. Start an IV in the other arm.

Correct answer: D

Rationale: The correct answer is to start an IV in the other arm. In this scenario, the patient is showing signs of Acute Compartment Syndrome, a serious condition that occurs due to increased pressure within a muscle compartment, leading to decreased blood flow and potential tissue damage. Starting an IV is crucial as the patient may require emergency surgery, such as a fasciotomy, to relieve the pressure and prevent further complications. Placing the patient in a supine position, asking about pain levels, or wrapping the fractured area, though important, are not the priority interventions in this critical situation where immediate medical intervention is necessary to prevent irreversible damage or loss of limb.

4. Which of the following measures would be appropriate for a nurse to teach the parent of a nine-month-old infant about diaper dermatitis?

• A. Use only cloth diapers that are rinsed in bleach
• B. Do not use occlusive ointments on the rash
• C. Use commercial baby wipes with each diaper change
• D. Discontinue a new food that was added to the infant's diet just prior to the rash

Correct answer: D

Rationale: Diaper dermatitis can be caused by various factors, one of which includes introducing new foods to the infant's diet. Discontinuing the new food that was added just before the rash can help identify and eliminate the potential cause. Options A and C are not directly related to addressing the cause of diaper dermatitis. While using cloth diapers rinsed in bleach may be a preventive measure for diaper dermatitis, it is not addressing a specific cause. Option B, advising against using occlusive ointments on the rash, may actually be beneficial in managing diaper dermatitis, but it does not address the cause of the condition.

5. A patient is scheduled for a computed tomography (CT) of the chest with contrast media. Which assessment finding should the nurse immediately report to the health care provider?

• A. Patient is claustrophobic.
• B. Patient is allergic to shellfish.
• C. Patient recently used a bronchodilator inhaler.
• D. Patient is not able to remove a wedding band.

Correct answer: B

Rationale: The correct answer is that the patient is allergic to shellfish. This is crucial because the contrast media used in CT scans is iodine-based, and individuals with iodine allergies, such as those allergic to shellfish, are at risk of adverse reactions. It is important to identify and address this allergy to prevent potential complications. The other options do not directly impact the safety or effectiveness of the CT scan with contrast media. Claustrophobia can be managed with patient support, the recent use of a bronchodilator inhaler does not typically affect the CT procedure, and not being able to remove a wedding band is not a critical concern for the scan itself.
