Test Bank Pharmacology and the Nursing Process

Correct Answer: A

Rationale: The correct answer is A because the nurse is using data validation by comparing the time of the last dressing change with the appearance of old and new drainage. This process ensures that the decision to remove the wound dressing is based on accurate and relevant information. By assessing both the time of the last dressing change and the characteristics of the drainage, the nurse is validating the need for the intervention. Option B is incorrect because administering pain medicine based solely on a patient's report of increased pain without further validation does not demonstrate data validation. Option C is incorrect as the nurse immediately requesting an order of potassium without further assessment of the patient's condition is not an example of data validation. Option D is incorrect as elevating a leg cast based solely on a patient's report of decreased mobility without further assessment does not involve data validation.

Correct Answer: A

Rationale: Step 1: Vitamin K is essential for the synthesis of clotting factors in the liver. Step 2: A splenectomy increases the risk of bleeding due to decreased platelet sequestration. Step 3: Preoperative Vitamin K injection helps correct any clotting deficiencies. Summary: - Choice B is incorrect as Vitamin K does not prevent infection. - Choice C is incorrect as Vitamin K does not directly promote healing. - Choice D is incorrect as Vitamin K does not dry secretions.

Correct Answer: C

Rationale: Rationale: 1. Insulin is a hormone produced by beta cells of the pancreas. 2. Beta cells are responsible for monitoring blood glucose levels and secreting insulin in response to high glucose levels. 3. Insulin helps regulate blood glucose by facilitating glucose uptake into cells. 4. Adenohypophysis secretes other hormones, not insulin. 5. Alpha cells of the pancreas secrete glucagon, not insulin. 6. Parafollicular cells of the thyroid secrete calcitonin, not insulin. Summary: Choice C is correct because insulin is indeed secreted from the beta cells of the pancreas. Choices A, B, and D are incorrect as they do not secrete insulin or are related to other hormones.

Correct Answer: B

Rationale: Step 1: Keeping the neck in midline helps prevent compression of the lymphatic vessels in the neck, reducing the risk of impaired skin integrity in Hodgkin's disease. Step 2: This position also helps maintain proper blood flow and lymphatic drainage in the neck area. Step 3: Trimming nails short, using mild soap, and supporting bony prominences are not directly related to preventing impaired skin integrity in Hodgkin's disease. Summary: Choice B is correct as it directly addresses the specific risk factor of impaired skin integrity in Hodgkin's disease, while the other choices are not as relevant to this particular concern.

Correct Answer: A

Rationale: The correct answer is A: Measure intake and output. Monitoring intake and output is crucial in assessing electrolyte imbalances and dehydration in clients with neurologic deficits. Electrolyte imbalances can lead to neurological complications, so accurate monitoring is essential. Mini-mental status and Glasgow Coma scale are assessments of mental status, not electrolyte balance. Vital signs can provide some information, but intake and output measurement is more specific for assessing electrolyte imbalances and dehydration.
