Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

Correct Answer: B

Rationale: The correct answer is B: Blurring of vision. This is typically the first symptom of a cataract because the clouding of the lens causes light to scatter, leading to blurred vision. Dry eyes (A) and eye pain (C) are not typically associated with cataracts. Loss of peripheral vision (D) is more commonly seen in conditions like glaucoma. In summary, blurring of vision is the hallmark symptom of cataracts due to lens clouding, distinguishing it from other eye conditions.

Correct Answer: B

Rationale: The correct answer is B: Administering platelets, as ordered to maintain an adequate platelet count. In ITP, the client has low platelet count leading to risk of bleeding. Administering platelets helps raise platelet levels and prevent bleeding complications. Teaching coughing and deep-breathing techniques (A) is important for preventing respiratory infections but not directly related to ITP. Giving aspirin (C) is contraindicated as it can further decrease platelet count. Administering stool softeners (D) is important for preventing straining but not specific to managing ITP.

Correct Answer: A

Rationale: The correct answer is A because exercising the bitten extremity can increase the spread of the venom. Choice B is correct as poisonous snake bites typically leave two fang marks. Choice C is correct as immediate severe pain and swelling are common symptoms of a poisonous snake bite. Choice D is incorrect as a tourniquet should not be used for snake bites as it can lead to complications such as tissue damage and increased risk of infection.

Correct Answer: A

Rationale: The correct answer is A: A complete thyroidectomy also. In the case of a cold nodule, which indicates potential malignancy, a total thyroidectomy is warranted to remove the entire thyroid gland to prevent the spread of cancer. A partial thyroidectomy, as in choices B and C, would not be sufficient in addressing malignancy. Administering thyroid medication, as in choice D, would not be appropriate for treating malignancy. Therefore, the correct approach is to perform a total thyroidectomy to ensure complete removal of the affected gland and to address both hyperthyroidism and potential malignancy.

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.
