Correct Answer: C

Rationale: The correct answer is that the level of the drug is 100 ml at 8 AM and is 80 ml at noon. With a basal rate of 10 mL per hour, a total of 40 mL should have been infused by noon, leaving only 60 mL in the container. Any amount greater than 60 mL at noon indicates that the pump is not functioning properly. Therefore, the finding of 80 mL at noon suggests the pump is not delivering the expected medication volume. Choices A and B are related to the client's symptoms and may indicate the need for pain management assessment but do not specifically indicate pump malfunction. Choice D, where the level drops to 50 mL at noon, would actually indicate that the pump is working effectively, as the expected volume has been delivered.

Correct Answer: D

Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.

Correct Answer: B

Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.

Correct Answer: B

Rationale: Bell's Palsy is characterized by the dysfunction of the Facial nerve, which is cranial nerve VII. This dysfunction leads to facial muscle weakness or paralysis, not affecting the arms. Choice A is incorrect as Bell's Palsy specifically involves facial muscles, not the arms. Choice C is incorrect as it incorrectly associates Bell's Palsy with a different condition, Cerebral Palsy. Choice D is incorrect as Bell's Palsy is not a side effect of a stroke but rather a distinct condition with its own etiology.

Correct Answer: B

Rationale: Amenorrhea is the correct term for the absence of menstrual periods in a woman of childbearing age. It is typically defined as no menstruation for at least three consecutive cycles or six months. Oligomenorrhea refers to infrequent or irregular menstrual periods rather than complete absence. Menorrhagia is characterized by excessive menstrual bleeding, not the absence of menstruation. Metrorrhagia involves irregular, acyclic bleeding between menstrual periods, which is different from the absence of menstruation.
