The nurse is caring for a client with diabetes insipidus. The nurse should anticipate the administration of:

Correct Answer: D

Rationale: The correct answer is D: vasopressin (Pitressin). In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), which leads to excessive urination and thirst. Vasopressin is a synthetic form of ADH that helps regulate water balance by reducing urine output. Therefore, administering vasopressin would help manage the symptoms of diabetes insipidus. Insulin (A) is used for diabetes mellitus, not diabetes insipidus. Potassium chloride (B) is used to correct potassium imbalances, not specific to diabetes insipidus. Furosemide (Lasix) (C) is a diuretic that increases urine output, which would worsen the symptoms of diabetes insipidus.

Correct Answer: B

Rationale: Step 1: The scenario describes Toni minimizing her visual problems, planning advanced degrees, seeking full-time jobs, and wanting more children. Step 2: Choice B is correct because it recognizes Toni's behavior as a coping mechanism to deal with her illness. Step 3: Minimizing visual problems and focusing on future goals can be a way for Toni to maintain a positive outlook and cope with her challenges. Step 4: Choices A, C, and D are incorrect because they do not address Toni's behavior as a coping mechanism. Choice A mentions euphoria, which is not supported by the scenario. Choice C and D do not acknowledge Toni's coping mechanism but instead focus on different aspects like disease process and physical functioning.

Correct Answer: B

Rationale: The correct answer is B: A hypothermia blanket. This is important because hypothermia can lead to complications such as shivering, increased risk of infection, and altered drug metabolism. Checking for the hypothermia blanket ensures Mrs. Zeno's temperature is regulated, promoting safety. A: A tracheostomy set is not directly related to Mrs. Zeno's immediate safety unless she has a tracheostomy in place. C: An intravenous set-up is important for administering medications, fluids, or blood products, but it is not directly related to Mrs. Zeno's safety at the bedside. D: A syringe and edrophonium HCl(Tensilon) is specific to a diagnostic test for myasthenia gravis, which may not be relevant to Mrs. Zeno's current condition or safety.

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.
