Correct Answer: C

Rationale: The correct answer is C: Sensorineural hearing loss. Hearing aids are most effective for sensorineural hearing loss as they amplify sound signals to compensate for damage to the inner ear hair cells or auditory nerve. This type of hearing loss is due to problems in the inner ear or auditory nerve, which can be partially compensated for by using hearing aids. The other choices, A: Conductive, B: Mixed, and D: Central, are not as effectively improved by hearing aids. Conductive hearing loss is usually due to problems in the outer or middle ear, which can often be treated with medical or surgical interventions. Mixed hearing loss involves a combination of conductive and sensorineural components, and may require a combination of interventions. Central hearing loss is due to problems in the central auditory pathways in the brain, and is not typically improved by hearing aids.

Correct Answer: A

Rationale: Step 1: Phenytoin is an anticonvulsant used to prevent seizures. Step 2: Anticonvulsants are often given before surgery to reduce the risk of seizures during and after the procedure. Step 3: In the context of intracranial surgery, controlling seizures is crucial to prevent complications like increased intracranial pressure. Step 4: Therefore, administering phenytoin before surgery helps in reducing the risk of seizures before and after the procedure. Summary: - Option B (avoid intraoperative complications) is too broad and doesn't directly relate to the use of phenytoin. - Option C (reduce cerebral edema) is not the primary indication for phenytoin in this scenario. - Option D (prevent postoperative vomiting) is not a common reason for administering phenytoin before intracranial surgery.

Correct Answer: C

Rationale: The correct answer is C: Neck vein distention. In SIADH, there is excess release of antidiuretic hormone leading to water retention and dilutional hyponatremia, causing fluid overload. This can manifest as neck vein distention due to increased venous pressure. Tetanic contractions (A) and weight loss (B) are not typical complications of SIADH; tetany is more associated with hypocalcemia and weight loss is not a common manifestation. Polyuria (D) is actually the opposite of what is seen in SIADH, which is characterized by water retention and concentrated urine.

Correct Answer: A

Rationale: Step-by-step rationale for why answer A is correct: 1. Assessing respiratory status is crucial during a choking incident to identify if the resident is unable to breathe. 2. In this scenario, the resident's inability to breathe indicates a life-threatening problem requiring immediate intervention. 3. CPR is initiated based on the assessment of the resident's breathing difficulty, emphasizing the critical nature of identifying a life-threatening issue. 4. The assessment of respiratory status directly informs the nurse's actions to address the immediate danger of choking. Summary: - Choice A is correct as assessing respiratory status helps identify life-threatening issues like choking. - Choice B is incorrect as the primary focus is on immediate intervention, not establishing a database. - Choice C is incorrect as the assessment is not for skill practice but for identifying a critical situation. - Choice D is incorrect as the goal is not to facilitate breathing but to address the immediate life-threatening problem.

Correct Answer: B

Rationale: Step 1: Activity intolerance is defined as insufficient physiological or psychological energy to endure or complete required or desired daily activities. Step 2: In the scenario, the patient experiences shortness of breath when getting out of bed, indicating decreased ability to tolerate physical activity. Step 3: This shortness of breath is a defining characteristic of activity intolerance as it reflects the patient's limited ability to perform activities of daily living. Step 4: Other symptoms like decreased oral intake, decreased oxygen saturation, and productive cough may be related to other health issues but are not specific to activity intolerance. Step 5: Therefore, choice B is the correct answer as it includes a key defining characteristic of activity intolerance, while other choices do not directly relate to the concept.
