Correct Answer: C

Rationale: The correct answer is C. Addressing the absence of three staff members should be the nurse manager's priority as it directly impacts staffing levels and patient care. This situation can lead to staffing shortages, affecting patient safety and workload distribution. Option A, lack of transport assistance, although important, can be addressed after ensuring adequate staffing. Option B involves a client's preference and can be addressed by assigning care appropriately. Option D, a disagreement between two nurses, is important but can be addressed after ensuring adequate staffing and patient care.

Correct Answer: A

Rationale: The correct answer is A: Social worker. A social worker can assist the parent in finding resources to afford the nebulizer. While a pharmacist may provide information about medications and devices, they may not have direct resources to address financial concerns. A respiratory therapist focuses on respiratory care but may not specialize in financial assistance. Referring to child protective services is not appropriate in this scenario as the parent's inability to afford a nebulizer does not indicate neglect or abuse.

Correct Answer: B

Rationale: Cultural differences are a common barrier to effective communication in healthcare. When individuals from different cultures interact in healthcare settings, varying communication styles, beliefs, values, and language barriers can hinder effective communication. This can lead to misunderstandings, misinterpretations, and ultimately impact the quality of care provided. Active listening (choice A) is a communication skill that helps improve understanding and can actually enhance communication. Clear language (choice C) is essential for effective communication and can help overcome barriers, rather than being a barrier itself. Empathy (choice D) is important in healthcare to understand patients' emotions and perspectives, but it is not a common barrier to effective communication.

Correct Answer: B

Rationale: The expected date of delivery is calculated by adding 9 months and 7 days to the last menstrual period. For April 20th, the expected date is January 27th. Therefore, the correct answer is B. Choice A, January 20th, is incorrect as it does not account for the additional 7 days. Choice C, January 29th, and Choice D, January 31st, are also incorrect as they do not consider the standard calculation method for estimating the due date.

Correct Answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.
