Correct Answer: C

Rationale: The correct answer is C: Computed tomography with contrast solution. This procedure involves the use of contrast agents that can trigger anaphylaxis due to the patient's allergic reaction to the contrast solution. Contrast solutions contain substances like iodine, which can cause severe allergic reactions in some individuals. Anaphylaxis is a life-threatening allergic reaction that can occur rapidly and requires immediate intervention. Assessing the risk for anaphylaxis during this procedure is crucial to prevent any potential harm to the patient. Incorrect choices: A: Administration of the measles-mumps-rubella (MMR) vaccine - While allergic reactions can occur with vaccines, the risk of anaphylaxis with MMR vaccine is lower compared to the contrast solution used in CT scans. B: Rapid administration of intravenous fluids - Rapid IV fluid administration can cause fluid overload or electrolyte imbalances, but it is not typically associated with triggering anaphylaxis. D: Administration of nebulized bronchodil

Correct Answer: D

Rationale: The correct answer is D: MRI. MRI is the most appropriate test for diagnosing spinal cord compression from a tumor as it provides detailed images of soft tissues, including the spinal cord and surrounding structures. It can accurately identify the location, size, and extent of the tumor. Anterior-posterior x-ray (A) is not as detailed and may not clearly show soft tissue abnormalities. Ultrasound (B) is not typically used for imaging the spinal cord and may not provide sufficient information. Lumbar puncture (C) is used to collect cerebrospinal fluid and is not helpful for diagnosing spinal cord compression from a tumor.

Correct Answer: B

Rationale: The correct answer is B: Montelukast (Singulair). Montelukast is a leukotriene receptor antagonist that helps prevent asthma exacerbations by reducing inflammation in the airways. It is used as a maintenance medication to control and prevent asthma symptoms. Diphenhydramine (A) is an antihistamine used for allergies, not asthma prevention. Albuterol sulfate (C) is a rescue inhaler used for acute asthma symptoms, not prevention. Epinephrine (D) is used for severe allergic reactions (anaphylaxis), not asthma prevention.

Correct Answer: B

Rationale: The correct answer is B: Flex head with chin tuck. This position helps prevent aspiration by closing off the airway during swallowing. Flexing the head and tucking the chin promotes safe swallowing and reduces the risk of choking. Placing food on the left side (choice C) is not relevant to addressing the patient's symptoms. Positioning in semi-Fowler's (choice A) may not directly address the swallowing difficulty. Offering fruit juice (choice D) does not address the patient's specific feeding needs and may not be safe if the patient has swallowing difficulties.

Correct Answer: C

Rationale: Step 1: Trigeminal neuralgia involves severe facial pain, often triggered by touch or movement. Step 2: Rubbing the eye on the affected side can trigger pain due to the trigeminal nerve involvement. Step 3: Therefore, advising the patient to avoid rubbing the eye on the affected side is crucial to prevent pain exacerbation and potential injury. Step 4: Choices A, B, and D are incorrect as they do not directly address the risk of injury related to trigeminal neuralgia.
