Correct Answer: B

Rationale: In a client with a C-6 spinal injury exhibiting shallow respirations and dyspnea, these signs could indicate respiratory compromise and potential respiratory failure. Intubation with an endotracheal tube may be necessary to secure the airway and support adequate oxygenation. Placing the client in reverse Trendelenburg position, administering pain medication, or instructing on deep breathing exercises would not directly address the urgency of the respiratory distress in this situation, making them incorrect choices.

Correct Answer: A

Rationale: The correct action for the nurse to implement in this situation is to advise the client to come to the clinic for an evaluation. Given the client's HIV-positive status and medication, it is crucial to assess the cough and fever promptly to identify the underlying cause. Increasing fluid intake (choice B) may be beneficial but does not address the need for evaluation. Taking an over-the-counter cough suppressant (choice C) may not be appropriate without knowing the cause of the symptoms. Advising the client to rest and call if the fever persists (choice D) delays the necessary evaluation and treatment.

Correct Answer: C

Rationale: The correct answer is to aspirate for blood return before injecting. This action helps ensure that the needle is not in a blood vessel, reducing the risk of injury. Using a 1-inch needle (Choice A) is a standard length for intramuscular injections but does not directly reduce the risk of injury. Selecting a large muscle for the injection (Choice B) is important for proper medication absorption but does not directly reduce the risk of injury. Massaging the injection site (Choice D) can help with medication absorption but does not reduce the risk of injury.

Correct Answer: D

Rationale: The maximum dosage the nurse should administer is 2 mg. This is calculated based on the prescription of 0.4 mg IM every 2 hours, not to exceed 5 doses. Since the medication is available in ampules containing 0.2 mg/ml, the nurse should administer 2 ml (0.2 mg/ml x 10 ml) for each dose, not exceeding 5 doses. Therefore, the nurse should limit the client's oral intake to 900 to 1,000 ml, to avoid exceeding the maximum dosage of 2 mg.

Correct Answer: A

Rationale: The correct answer is to assess the need for continued restraint. This is the most important nursing intervention as it ensures the client's safety and autonomy. Checking for urinary incontinence (Choice B) may be important but is not the priority in this situation. Determining skin integrity under the vest (Choice C) is essential but not as crucial as assessing the need for continued restraint. Performing range-of-motion exercises (Choice D) is important for client mobility but not the priority when a restraint is in place.
