Rationale: The correct answer is A: Diaphoresis. Diaphoresis, which refers to excessive sweating, is a classic symptom of hypoglycemia. Instructing the client to monitor for diaphoresis is crucial as it can help them recognize and address hypoglycemic events promptly. Polyuria (excessive urination), abdominal pain, and thirst are not typical signs of hypoglycemia. Polyuria is more commonly associated with conditions like diabetes mellitus, while abdominal pain and thirst are not specific indicators of low blood sugar levels.

Correct Answer: C

Rationale: 1 cm of water in the water seal chamber is insufficient to ensure proper functioning of the chest tube. The water seal chamber typically requires a water level of 2 cm. Tidaling with spontaneous respirations (choice A) is an expected finding indicating proper functioning. Having the drainage collection chamber 1/3 full (choice B) is within the normal range. A suction chamber pressure of -20 cm H2O (choice D) is an appropriate level for chest tube drainage.

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: C

Rationale: In cases of magnesium sulfate toxicity, calcium gluconate is the antidote as it helps reverse the effects. Positioning the client supine (Choice A) may not directly address magnesium sulfate toxicity. Administering dextrose 5% (Choice B) is not the correct intervention for magnesium sulfate toxicity. Methylergonovine IM (Choice D) is used to manage postpartum hemorrhage, not magnesium sulfate toxicity.
