Correct Answer: B

Rationale: Step 1: Guillain-Barre Syndrome (GBS) is characterized by a rapid onset of weakness and tingling sensations in the legs. Step 2: Paresthesia refers to abnormal sensations like tingling or numbness, which is a common initial neurological symptom of GBS. Step 3: Absent tendon reflexes may occur in GBS due to muscle weakness but are not typically the initial symptom. Step 4: Dysrhythmias and transient hypertension are not typical symptoms of GBS and are not associated with its initial presentation. In summary, choice B is correct as paresthesia of the legs is a hallmark initial neurological symptom of Guillain-Barre Syndrome, while choices A, C, and D are incorrect as they do not align with the typical presentation of GBS.

Correct Answer: A

Rationale: The correct answer is A. Transporting specimens of body fluid in leakproof containers reduces the risk of exposure to HIV/AIDS. This precaution ensures that any potentially infectious material is securely contained. Choice B is incorrect as fusion inhibitors are not prescribed for reducing occupational risks. Choice C is incorrect as it does not directly address reducing occupational risks related to HIV/AIDS. Choice D is incorrect as it is essential for a nurse to clean the client's room, but with proper precautions in place to prevent exposure to bodily fluids.

Correct Answer: B

Rationale: The correct answer is B: Block beta stimulation in the heart. Propranolol is a beta-blocker that works by blocking the beta receptors in the heart, which reduces the heart's workload and oxygen demand, making it an effective treatment for angina. By blocking beta stimulation, propranolol helps to decrease heart rate, blood pressure, and myocardial contractility. This ultimately improves oxygen supply to the heart muscle. Explanation for other choices: A: Act as a vasoconstrictor - Propranolol does not act as a vasoconstrictor; it actually can cause vasodilation in some cases. C: Act as a vasodilator - Propranolol is not primarily a vasodilator; its main action is to block beta stimulation in the heart. D: Increase the heart rate - Propranolol actually decreases heart rate by blocking beta receptors in the heart.

Correct Answer: C

Rationale: The correct answer is C: Eating. Chewing food can trigger trigeminal nerve pain due to the movement and pressure applied on the nerve. The other choices (A: Sleeping, B: Reading, D: Cooking) do not involve the same level of jaw movement and pressure on the trigeminal nerve, thus are less likely to aggravate the pain. Therefore, eating is the most likely action to worsen trigeminal neuralgia symptoms in this scenario.

Correct Answer: A

Rationale: Rationale: 1. A: Blood pressure apparatus is essential to monitor for any signs of bleeding or clot formation after carotid angioplasty. 2. B: IV infusion stand is important but not the priority for immediate postoperative monitoring. 3. C: Call bell is important for the client to call for assistance but not the priority for immediate postoperative care. 4. D: Endotracheal intubation is not necessary after a carotid angioplasty and is not a priority item for bedside care. Summary: Monitoring blood pressure is crucial for detecting complications post carotid angioplasty. IV stand, call bell, and endotracheal intubation are important but not the priority in this scenario.
