A client with a history of cardiac dysrhythmias is admitted to the hospital with the diagnosis of dehydration. The nurse should anticipate that the physician will order;

Correct Answer: B

Rationale: Step-by-step rationale for choice B being correct: 1. Dehydration leads to electrolyte imbalances, which can exacerbate cardiac dysrhythmias. 2. Small frequent intake of fluids like juices, broth, or milk helps in gradual rehydration without overwhelming the cardiovascular system. 3. This approach allows for better absorption of fluids and nutrients, promoting hydration without causing sudden shifts in electrolyte levels. Summary of why other choices are incorrect: A: Just drinking a glass of water every hour may not address electrolyte imbalances or provide adequate hydration for a client with cardiac dysrhythmias. C: NG replacement may not be necessary if the client can tolerate oral intake, and it is more invasive than needed. D: A rapid IV infusion may lead to sudden changes in electrolyte levels, potentially worsening the dysrhythmias.

Correct Answer: C

Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used. Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly. Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride. Summary: - Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration. - Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride. - Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.

Correct Answer: D

Rationale: The correct answer is D. Epinephrine, when applied locally, constricts blood vessels, reducing blood flow and slowing down bleeding. This vasoconstrictive effect helps control nosebleeds effectively. Choice A is incorrect because although epinephrine can raise blood pressure, it is not the primary mechanism for treating nosebleeds. Choice B is incorrect as epinephrine's bronchodilation effect is not relevant in this context. Choice C is incorrect as while promoting blood clotting is beneficial, epinephrine primarily acts by vasoconstriction to control bleeding.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Acute bronchitis is characterized by inflammation of the bronchial tubes. 2. An initial sign of acute bronchitis is a nonproductive cough due to irritation of the bronchial tubes. 3. Anorexia and labored breathing may occur later as the condition progresses. 4. Gastric ulceration is not typically associated with acute bronchitis. Therefore, choice A (Nonproductive cough) is the correct answer as it aligns with the characteristic symptom of acute bronchitis, while the other choices are not typically observed in the initial stages of the condition.

Correct Answer: A

Rationale: The correct answer is A: Naturally acquired passive immunity. This type of immunity occurs when antibodies are passed from mother to baby through the placenta or breast milk, providing temporary protection. The baby does not produce its antibodies, hence it is passive. Choice B, naturally acquired active immunity, involves the body producing its antibodies after exposure to a pathogen. Choice C, artificially acquired passive immunity, involves receiving preformed antibodies from an external source. Choice D, artificially acquired active immunity, involves the body producing antibodies in response to vaccination.
