Correct Answer: A

Rationale: Using Naegele's rule, to calculate the expected delivery date, you add one year, subtract three months, and add seven days to the first day of the last menstrual period. If the last menstrual period was in October, adding one year gives October of the following year. Subtracting three months gives July, and adding seven days gives the expected delivery date of July 11th. Therefore, the correct answer is 711. Choice B (1011) is incorrect as it doesn't follow Naegele's rule calculations. Choices C (411) and D (1211) are also incorrect as they do not align with the correct application of Naegele's rule.

Correct Answer: D

Rationale: An absolute neutrophil count of 75/mm³ is critically low and places the client at high risk for infection, necessitating immediate intervention. Neutropenia increases susceptibility to infections, making it essential to report this finding promptly. The other options, such as pain level in pleurisy, drainage amount from a drain, and heart rate postoperatively, are important but do not indicate an immediate life-threatening condition that requires urgent provider notification.

Correct Answer: A

Rationale: The correct answer is A: WBC 3,000/mm³. A WBC count of 3,000/mm³ indicates neutropenia, which is a condition characterized by a low level of white blood cells, specifically neutrophils. Neutropenia increases the risk of infection and requires immediate medical attention, especially in clients undergoing chemotherapy. Reporting this result to the provider promptly is crucial for further evaluation and intervention. Choices B, C, and D are within normal ranges and do not pose an immediate risk to the client's health. Hemoglobin of 12 g/dL, platelet count of 250,000/mm³, and serum sodium of 140 mEq/L are all normal values and would not typically require immediate reporting unless there are specific concerns related to the individual client's condition.

Correct Answer: D

Rationale: The correct answer is D: 'This medication helps decrease swelling and mucus production.' Montelukast is used for long-term asthma management as it helps reduce inflammation and mucus production in the airways. It is not appropriate for acute asthma attacks. Choice A is incorrect because montelukast is not a rescue medication for acute attacks. Choice B is incorrect because montelukast is not specifically taken before exercise. Choice C is incorrect because montelukast is usually taken regularly, not just for a short duration.
