Correct Answer: B

Rationale: The correct answer is B. Compartment syndrome is a serious condition that can occur following trauma or surgery, leading to compromised neurovascular status in the affected limb. Symptoms include pain, paresthesia (tingling sensation), and diminished pulses. If left untreated, compartment syndrome can result in tissue damage and potential loss of limb function. Options A, C, and D are incorrect because they do not directly address the neurovascular compromise associated with compartment syndrome.

Correct Answer: B

Rationale: In this scenario, if the nurse's finger is stuck with the needle before administering the injection, the correct action is to prepare the medication using a new syringe. This step is crucial to prevent contamination and ensure the safety of the patient. Going to the emergency room to have blood drawn is unnecessary and does not address the immediate issue of contamination. Applying clean gloves is important for infection control but does not address the potential contamination from the needlestick. Reviewing the medical history in the client's chart is important for overall patient care but is not the priority in this situation where immediate action is required to prevent harm.

Correct Answer: C

Rationale: Ineffective breathing pattern is the highest priority nursing problem for a client with Guillain-Barre syndrome due to the potential risk of respiratory failure. As the paralysis ascends, it can affect the muscles needed for breathing, leading to respiratory compromise. Addressing this problem promptly is crucial to prevent respiratory distress and failure. Choices A, B, and D are also important nursing problems in Guillain-Barre syndrome, but ensuring effective breathing takes precedence over coping, nutrition, and mobility due to the immediate threat it poses to the client's life.

Correct Answer: C

Rationale: The correct answer is C. Some salt substitutes can be high in potassium, which may not be suitable for clients with heart failure. Option A is correct as using lemon juice and herbs for flavoring is a good low-sodium alternative. Option B is also correct as canned soups and frozen dinners are typically high in sodium content. Option D is correct as checking food labels for sodium content is an essential part of managing a low-sodium diet. Therefore, the client's statement about using salt substitutes needs correction as it can introduce high levels of potassium, which may not be recommended for individuals with heart failure.

Correct Answer: C

Rationale: In this scenario, the client needs to avoid weight-bearing on the left leg. A 4-point crutch gait involves using both crutches and both legs, making it more appropriate for weight-bearing restrictions. Encouraging the use of a 3-point gait (choice A) would not provide adequate support for the client's condition. While using a wheelchair (choice B) could be an option, instructing the client in a 4-point crutch gait would promote mobility while adhering to weight-bearing restrictions. A 2-point crutch gait (choice D) involves using both crutches and one leg, which is not suitable for avoiding weight-bearing on the left leg.
