Correct Answer: A

Rationale: The correct answer is A: Antihistamines. Labyrinthitis is an inner ear condition often caused by inflammation or infection. Antihistamines help reduce symptoms like vertigo and dizziness by decreasing inflammation and fluid buildup in the inner ear. Anti-inflammatories (choice B) may help with inflammation but are not as effective for inner ear conditions. Antispasmotics (choice C) are not typically used for treating labyrinthitis. Antiemetics (choice D) are used to control nausea and vomiting, which can be symptoms of labyrinthitis but do not address the underlying cause.

Correct Answer: C

Rationale: The correct answer is C: Weak, slow pulse. Circulatory overload typically presents with signs of fluid volume excess, such as moist gurgling respirations, distended neck veins, dyspnea, and coughing. A weak, slow pulse is not a characteristic sign of circulatory overload, as the heart rate may actually be elevated due to the increased fluid volume. Therefore, a weak, slow pulse would not be likely to occur in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Right ventricular hypertrophy. Elevated pulmonary vascular pressures lead to increased resistance in the pulmonary circulation, causing the right ventricle to work harder to pump blood to the lungs. Over time, this can result in hypertrophy of the right ventricle as it adapts to the increased workload. Left atrial atrophy (A) and right atrial atrophy (C) are unlikely as the atria are not directly affected by elevated pulmonary pressures. Left ventricular hypertrophy (B) is not the correct choice as it typically occurs in response to systemic hypertension, not pulmonary hypertension.

Correct Answer: A

Rationale: The correct answer is A because taking a laxative like Senokot can affect the results of an IVP by altering bowel motility and potentially causing inaccurate imaging. Choice B is related to bladder sensation, which is not directly relevant to an IVP. Choice C indicates a possible allergic reaction to mussels, which is unrelated to the procedure. Choice D mentions headaches, which are also not directly linked to an IVP. In summary, only choice A directly impacts the accuracy of the IVP results, making it the most concerning statement for Nurse Aura.

Correct Answer: B

Rationale: The correct answer is B: Patient expectations. In a nursing health history, the nurse focuses on understanding the patient's expectations, needs, and preferences to provide patient-centered care. This step is essential for building rapport, establishing trust, and tailoring care plans to meet the patient's individual needs. Incorrect choices: A: Nurse’s concerns - This is not the primary focus during a nursing health history. The nurse should prioritize understanding the patient's perspective. C: Current treatment orders - While important, this is typically addressed during the assessment phase, not specifically in the nursing health history. D: Nurse’s goals for the patient - The nurse's goals should align with the patient's goals, making understanding the patient's expectations crucial.
