Correct Answer: B

Rationale: The correct answer is B (4 hours) because parenteral ampicillin should be administered within 1 hour of mixing. This is crucial to ensure efficacy and prevent bacterial growth in the solution. Choice A (1 hour) is incorrect because it does not allow enough time for administration after mixing. Choice C (2 hours) is also incorrect as it exceeds the recommended time limit. Choice D (8 hours) is incorrect as it exceeds the safe window for administration post-mixing, increasing the risk of bacterial contamination and reduced effectiveness. Thus, the optimal timeframe for administering parenteral ampicillin after mixing is within 4 hours to maintain its therapeutic benefits.

Correct Answer: C

Rationale: The correct answer is C: Cold sensitivity. Severe anemia leads to decreased oxygen delivery to tissues, causing symptoms like pallor, fatigue, and dyspnea on exertion due to the body compensating for low oxygen levels. Cold sensitivity is not a common symptom associated with anemia. The other choices are directly related to severe anemia due to the lack of oxygen delivery to tissues.

Correct Answer: B

Rationale: The correct answer is B because a client's medical history of allergy to iodine or seafood is crucial for urinary diversion assessment to prevent potential adverse reactions during procedures involving contrast media or seafood-based medications. It is essential to ensure the client's safety and avoid any allergic reactions. Choice A is incorrect because assessing sexual function is not directly related to urinary diversion assessment. Choice C is also incorrect as urinary diversion does not typically affect nervous control. Choice D is irrelevant to the assessment of a client undergoing urinary diversion.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons, muscles, or glands. Its structure allows for the rapid transmission of electrical signals. Rationale: 1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect. 2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect. 3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen therapy. This is the priority intervention because a high temperature and diaphoresis indicate potential respiratory distress. Oxygen therapy can help improve oxygenation and support respiratory function. Providing frequent linen changes (B) is important for hygiene but not the priority. Fluid intake (C) is essential but not as urgent as addressing respiratory distress. Maintaining complete bed rest (D) may be necessary but addressing oxygenation takes precedence in this case.
