Correct Answer: D

Rationale: Correct! A calcium level of 8.0 mg/dL indicates hypocalcemia. Hypocalcemia can lead to increased neuromuscular excitability, manifesting as tingling of the extremities. Choices A, B, and C are incorrect findings associated with other electrolyte imbalances or conditions and are not typically related to hypocalcemia. Constipation is commonly seen in hypokalemia, absent deep-tendon reflexes are associated with hypermagnesemia, and nausea and vomiting are more indicative of hypercalcemia.

Correct Answer: D

Rationale: Managing a patient with sepsis requires a multi-faceted approach. Administering IV antibiotics is crucial to combat the underlying infection. Monitoring vital signs such as heart rate, blood pressure, respiratory rate, and temperature helps assess the patient's response to treatment and identify any deterioration. Administering fluids is essential to maintain adequate blood pressure and organ perfusion. Therefore, all the options are integral components of sepsis management, making 'All of the above' the correct answer. Choices A, B, and C are all essential in the comprehensive care of a patient with sepsis. Omitting any of these aspects can lead to suboptimal outcomes, as each plays a critical role in addressing different aspects of sepsis management.

Correct Answer: B

Rationale: When a nurse assesses a client with signs of delirium, the priority in determining the cause should be focusing on fluid and electrolyte imbalances. Delirium can often be linked to imbalances in these essential elements, making it crucial to address them promptly. While medication history, psychosocial stressors, and environmental factors can also contribute to delirium, they should be assessed after addressing fluid and electrolyte imbalances due to their immediate impact on cognitive function.

Correct Answer: D

Rationale: The correct answer is D because the inability to perform activities of daily living, such as opening a milk carton, suggests difficulties with fine motor skills. Occupational therapists specialize in helping individuals regain independence in such tasks. Choices A, B, and C do not specifically address fine motor skills related to activities of daily living, therefore not warranting an occupational therapy referral. Choice A mentions lifting the arm, which involves gross motor skills rather than fine motor skills. Choice B involves holding a pencil, which is more related to hand dexterity and strength rather than fine motor skills. Choice C, opening a milk carton, could be related to fine motor skills but is not as clear-cut as the inability described in Choice D, where the frustration is explicitly about the inability to perform a daily living task.

Correct Answer: D

Rationale: After surgery, key signs of infection include redness, swelling, and fever. Redness and swelling can indicate inflammation at the surgical site, while fever is a systemic response to infection. Choosing 'All of the above' (Option D) is the correct answer because all three signs are commonly associated with post-surgical infections. Options A, B, and C are incorrect as each of them individually can be a sign of infection, but considering all three together provides a more comprehensive assessment for post-operative infection.
